Why This Is the Most Litigated Area of GST: ITC is the backbone of GST — the mechanism that prevents cascading tax and reduces business costs. Yet Section 17(5) creates a long list of situations where ITC is categorically denied. Every year, crores of rupees in ITC are wrongly claimed (leading to demands) or wrongly denied (leaving money on the table). The Safari Retreats saga — a Supreme Court victory reversed by retrospective legislation — shows how volatile this area can be. This guide covers every blocked credit, every exception, and every landmark development through May 2026.

1. ITC — The Foundation: Conditions Under Section 16
Before examining blocked credits, understand that ITC can be claimed ONLY when ALL four conditions under Section 16(1) and 16(2), CGST Act are simultaneously met:
| Condition | Requirement |
|---|---|
| 1. Possession of tax invoice | Must hold a valid tax invoice, debit note, or other prescribed document § 16(2)(a) |
| 2. Goods/services received | Must have actually received the goods or services (or deemed receipt per bill-to-ship-to arrangements) § 16(2)(b) |
| 3. Tax actually paid | The supplier must have paid the GST to the government (verified via GSTR-2B from January 2022) § 16(2)(c) |
| 4. GST return filed | The recipient must have filed their own GST return § 16(2)(d) |
| 5. Within time limit | Claimed before 30 November of the following financial year or date of annual return (GSTR-9) filing, whichever is earlier § 16(4) |
Even if all five conditions are met, ITC is still unavailable if the item falls under Section 17(5) — the blocked credit provisions. Section 17(5) is a non-obstante clause that overrides Section 16(1). The Supreme Court confirmed in Safari Retreats that Section 17(5) is constitutionally valid.
2. Section 16(4): The Time Limit Trap for ITC Claims
Even legitimate, un-blocked ITC must be claimed within the time limit. Missing this is irreversible — there is no provision for condonation of delay.
Section 16(4), CGST Act — Time Limit:
A registered person shall not take input tax credit in respect of any invoice or debit note for supply of goods or services after the thirtieth day of November following the end of the financial year to which such invoice or debit note pertains OR the date of furnishing of the annual return (GSTR-9), whichever is earlier.
A registered person shall not take input tax credit in respect of any invoice or debit note for supply of goods or services after the thirtieth day of November following the end of the financial year to which such invoice or debit note pertains OR the date of furnishing of the annual return (GSTR-9), whichever is earlier.
| Invoice FY | Last date to claim ITC (if GSTR-9 filed by 31 Dec) | What happens after? |
|---|---|---|
| FY 2024-25 (April 2024 – March 2025) | 30 November 2025 OR date of GSTR-9 for FY 24-25, whichever earlier | ITC permanently lost |
| FY 2025-26 (April 2025 – March 2026) | 30 November 2026 OR date of FY 25-26 GSTR-9 | ITC permanently lost after that date |
🆕 Finance Act 2024 — Supplier-Side Amendment to § 16(2)(c):
If a supplier files their GSTR-1 after the applicable due date (e.g., a rectified/amended return or late filing), the recipient can still claim ITC once the supplier’s tax actually reflects in the recipient’s GSTR-2B — provided the recipient’s own time limit under § 16(4) has not expired. This amendment addresses situations where good-faith recipients were losing ITC purely because their supplier was tardy in filing.

This amendment addresses situations where good-faith recipients were losing ITC purely because their supplier was tardy in filing.
⚖️ Supreme Court — Safari Retreats (Oct 2024) on Section 16(4):
The Supreme Court upheld the constitutional validity of Section 16(4). The court held that the legislature has full competence to impose time limits on ITC claims as a fiscal policy measure, and this does not violate fundamental rights. There is no constitutional protection for delayed ITC claims — the time limit is final.

3. Section 17(5): The Master List of Blocked Credits
Section 17(5) categorically denies ITC on the following — regardless of business purpose:
| Clause | Category Blocked | Exceptions (ITC Allowed) |
|---|---|---|
| § 17(5)(a) | Motor vehicles for transport of persons (capacity ≤ 13 including driver) | Supply of such vehicles; passenger transport business; driving school |
| § 17(5)(aa) | Vessels and aircraft | Supply; transport of passengers/goods; training on navigation/flying |
| § 17(5)(ab) | Insurance, maintenance, repair of blocked vehicles/vessels/aircraft | Same exceptions as (a) and (aa) |
| § 17(5)(b)(i) | Food and beverages, outdoor catering | Same category as outward supply; obligatory under any law |
| § 17(5)(b)(ii) | Beauty treatment, health services, cosmetic and plastic surgery | Same category as outward supply |
| § 17(5)(b)(iii) | Membership of clubs, health and fitness centres | No exception |
| § 17(5)(b)(iv) | Rent-a-cab, life insurance, health insurance | Same category as outward supply; obligatory under any law |
| § 17(5)(b)(v) | Travel benefits to employees on vacation (LTA/LTC) | No exception |
| § 17(5)(c) | Works contract services for construction of immovable property (not plant and machinery) | Further supply of works contract; plant and machinery construction |
| § 17(5)(d) | Goods and services for construction of immovable property on own account (not plant and machinery) | Plant and machinery; not on own account |
| § 17(5)(e) | Goods or services for personal consumption | None |
| § 17(5)(f) | Goods lost, stolen, destroyed, written off, disposed as gift or free samples | None |
| § 17(5)(g) | Tax paid under composition scheme (§ 10); tax paid under § 74 (fraud/evasion); § 129 (detention); § 130 (confiscation) | None |
4. Motor Vehicles — When ITC is Blocked and When Allowed
This is the most frequently encountered blocked credit for most businesses. The rule — and its exceptions — must be precisely understood.
When ITC is BLOCKED § 17(5)(a) CGST
Motor vehicles designed for transportation of persons with seating capacity of 13 or fewer persons (including driver). This includes:
- Cars, SUVs (hatchbacks, sedans, MPVs — all personal passenger cars)
- Two-wheelers (motorcycles, scooters used for business visits)
- Employee pickup vehicles with ≤12+1 capacity
When ITC IS Allowed — Exceptions
| Situation | ITC Available? | Example |
|---|---|---|
| Business of further supply of such vehicles | ✅ Yes | Car dealer (Maruti showroom) buys cars for resale → ITC on cars purchased for stock |
| Business of transportation of passengers | ✅ Yes | Ola/Uber fleet operator, bus operator, taxi company → ITC on vehicles used for hire |
| Business of imparting training on driving | ✅ Yes | Driving school buys cars for training → ITC available |
| IT company buys car for MD | ❌ No | Passenger car for internal use → blocked regardless of business purpose |
| Pharma company buys bikes for sales reps | ❌ No | Two-wheelers for business travel → blocked |
| Bus company buys 50-seater bus | ✅ Yes | Seating >13 passengers → NOT covered under § 17(5)(a) → ITC allowed |
| Renting of motor car (passenger ≤13) to body corporate | ❌ Depends | If car is hired from a supplier who charges 18% GST on forward charge → ITC available to recipient. If paid under RCM at 5% → ITC available on RCM payment. |
The 13-person rule explained:
Only vehicles with seating capacity of 13 OR FEWER (including driver) are blocked. A mini-bus with 20 seats = seating capacity of 20 = NOT blocked under § 17(5)(a). A typical office car (5-seater) = 5 including driver = blocked. A large van with 14 seats (13 passengers + driver) = exactly at the boundary — 14 total including driver → NOT blocked (the cap is “not more than 13” including driver).

A large van with 14 seats (13 passengers + driver) = exactly at the boundary — 14 total including driver → NOT blocked (the cap is “not more than 13” including driver).
5. Vessels & Aircraft — ITC Rules § 17(5)(aa) CGST
ITC on vessels and aircraft is blocked — similar to motor vehicles — with the same exceptions for commercial use:
| Asset | ITC Blocked? | Exception |
|---|---|---|
| Private aircraft (corporate jet) | ❌ Blocked | Only if company’s business is transporting passengers/goods or training on flying |
| Luxury yacht (corporate hospitality) | ❌ Blocked | If used commercially for passenger transport — ITC available |
| Commercial airline’s aircraft | ✅ ITC Available | Airline’s core business is transportation of passengers → exception applies |
| Cargo shipping vessel (logistics company) | ✅ ITC Available | Business of transporting goods → exception applies |
| Flying school aircraft | ✅ ITC Available | Training on flying → exception applies |
6. Insurance, Servicing & Repairs of Blocked Vehicles § 17(5)(ab) CGST
The block extends beyond the vehicle purchase to all related services — if the vehicle itself is blocked, ITC on its:
- General insurance (comprehensive/third-party)
- Servicing and maintenance (periodic service, oil change, tyre replacement)
- Repair costs (accident repair, bodywork)
- Annual maintenance contracts
…is also blocked. The same exceptions apply — if the vehicle qualifies for ITC (seating >13, commercial transport, etc.), the insurance/maintenance ITC is also available.
Company Car — Complete ITC Block
ABC Pvt. Ltd. purchases a Toyota Fortuner (7-seater) for its CEO at ₹55 lakh. It also pays ₹60,000 annual insurance and spends ₹15,000 on quarterly servicing.
- ITC on Fortuner purchase (28% GST on car = ₹12.68L approx): BLOCKED
- ITC on insurance (18% GST = ₹10,800): BLOCKED
- ITC on servicing (18% GST = ₹2,700/quarter): BLOCKED
- Total ITC denied: ~₹12.82L for purchase year + ₹21,600/year for running costs
7. Food, Beverages & Outdoor Catering — Categorical Block § 17(5)(b)(i) CGST
ITC on food and beverages is blocked regardless of business purpose — even if feeding employees is a legal obligation or productivity measure.
| Expense | ITC Status | Reason |
|---|---|---|
| Office canteen (employee meals) | ❌ Blocked | Food supply — even to employees — blocked unless the business’s own outward supply is food |
| Client entertainment — restaurant bills | ❌ Blocked | Business meal — blocked completely |
| Conference/training meals (outdoor catering) | ❌ Blocked | Outdoor catering — explicitly blocked |
| Factory canteen (mandatory under Factories Act) | ❌ Blocked | Exception: ITC allowed IF maintaining the canteen is obligatory under any law — but CBIC circulars have been restrictive on this exception’s scope |
| Hospital buying food for patients | ✅ Allowed | Hospital’s outward supply includes food to patients — same category exception applies |
| Restaurant buying food ingredients | ✅ Allowed | Business of further supply of food — exception applies |
| Airline buying in-flight meals | ✅ Allowed | Airline provides meals as part of service — outward supply exception |
⚠️ Factory canteen — the “obligatory under law” controversy:
Section 46 of the Factories Act mandates canteens in factories with 250+ workers. Many manufacturers claimed ITC on factory canteen expenses citing this legal obligation — and the “obligatory under any law” exception in § 17(5)(b). CBIC Circular 172/04/2022-GST clarified that ITC on canteen services is available if it’s mandatorily required under law, but only for the amount the employer pays — not the subsidised employee contribution portion. Several AAR rulings have gone both ways. This remains a litigation zone.

8. Beauty Treatment, Health Services, Cosmetic & Plastic Surgery § 17(5)(b)(ii) CGST
ITC on beauty treatment, health services, cosmetic and plastic surgery is blocked. Exception: if the business’s own outward supply is the same service.
| Expense | ITC Status |
|---|---|
| Corporate gym membership for employees | ❌ Blocked (also club membership — § 17(5)(b)(iii)) |
| Employee health checkup (annual) | ❌ Blocked (health service) |
| Cosmetic surgery for an employee (covered by company) | ❌ Blocked |
| Beauty parlour chain buys beauty products/services for its own salon | ✅ Allowed (outward supply is same category) |
| Hospital providing plastic surgery services | ✅ Allowed (further supply exception) |
| Pre-employment medical test for new hire | ❌ Blocked — even if business necessity, health service is categorically blocked |
9. Life Insurance & Health Insurance — Post-Rationalization Position § 17(5)(b)(iv) CGST
ITC on life insurance and health insurance for employees is blocked under § 17(5)(b)(iv) — unless:
- The business’s own outward supply is insurance services (insurance companies); OR
- It is obligatory under any law (e.g., ESIC-equivalent, mandatory employee insurance under some regulations)
🆕 September 2025 — Life Insurance Now Exempt from GST:
Following the 56th GST Council, individual life insurance (term, ULIP, endowment) is now exempt from GST. This means employers who buy group term life insurance for employees will no longer pay GST on the premium — eliminating the ITC question on life insurance for most companies.
Health insurance remains taxable at 18% — ITC remains blocked for employer-paid employee health insurance under § 17(5)(b)(iv), subject to exceptions. The government’s proposal to exempt health insurance from GST was under consideration as of May 2026 but not yet implemented.

ESIC context: Companies with employees registered under ESIC (Employees’ State Insurance Corporation) pay ESIC contributions — which are not GST and have no ITC implication. But additional mediclaim/health insurance provided voluntarily by employers attracts 18% GST — and that GST is blocked ITC for the employer.
10. Travel Benefits — LTA and Vacation Travel for Employees § 17(5)(b)(v) CGST
Travel benefits extended to employees on vacation or on leave — specifically Leave Travel Allowance (LTA) / Leave Travel Concession (LTC) reimbursements — are blocked. There is no exception to this block.
- ✗ GST on air tickets reimbursed under LTA — ITC blocked
- ✗ GST on hotel stays booked for LTA trips — ITC blocked
- ✓ Business travel (not vacation) — air tickets, hotels for work travel — ITC allowed (not vacation, not “travel benefits on leave”)
- ✓ Travel agency services for booking business travel — ITC allowed
The LTA ITC trap: During COVID, the government introduced the LTC Cash Voucher Scheme allowing employees to spend LTA money on goods/services instead of travel. Several companies tried to claim ITC on these purchases — courts held the block still applied as the underlying entitlement was a “travel benefit on vacation.”
11. Works Contract Services for Immovable Property — Section 17(5)(c)
§ 17(5)(c) CGST blocks ITC on works contract services received for the construction of an immovable property (other than plant and machinery). Two exceptions:
- Further supply of works contract: If a sub-contractor receives works contract services and uses them to further supply works contract services to the main contractor — ITC is available. This preserves the ITC chain in sub-contracting.
- Plant and machinery: If the works contract is for construction of plant and machinery — ITC is available (see Section 12 below for the Safari Retreats controversy on what qualifies as “plant and machinery”).
Works Contract ITC — Who Gets It and Who Doesn’t
| Party | Transaction | ITC Status |
|---|---|---|
| NHAI (building a highway for itself) | Receives works contract from ABC Construction | ❌ Blocked — NHAI is constructing immovable property “on its own account” |
| ABC Construction (main contractor) | Receives sub-contract works from XYZ Civil | ✅ Allowed — ABC is using works contract services to further supply works contract to NHAI |
| XYZ Civil (sub-contractor) | Receives materials supply (not works contract) for the project | ✅ Allowed — materials are inputs for further works contract supply |
| IT company building its own office | Pays contractor for office construction | ❌ Blocked — building own immovable property; no works contract exception applies |
12. Construction of Immovable Property — Section 17(5)(d): The Safari Retreats Complete Story
This is the most litigated, most legally eventful, and most rapidly evolving area of GST ITC law. The timeline from 2024 to 2025 reads like a legal thriller.
12.1 The Original Provision — What Section 17(5)(d) Said
Original Section 17(5)(d), CGST Act (2017 to Sept 2025):
ITC shall not be available in respect of goods or services or both received by a taxable person for construction of an immovable property (other than plant or machinery) on his own account including when such goods or services or both are used in the course or furtherance of business.
ITC shall not be available in respect of goods or services or both received by a taxable person for construction of an immovable property (other than plant or machinery) on his own account including when such goods or services or both are used in the course or furtherance of business.
The key exception was “plant or machinery.” If a structure qualified as a “plant” OR as “machinery” — ITC was available. The definition of “plant and machinery” in the Explanation to Section 17 excluded land, buildings, and civil structures. But the question was: can a building itself be a “plant”?
12.2 The Safari Retreats Judgment — Supreme Court (3 October 2024)
⚖️ Chief Commissioner of CGST v. Safari Retreats Pvt. Ltd. [Supreme Court, 3 October 2024]:
Background: Safari Retreats built a shopping mall and claimed ITC on all goods/services used in construction. The Revenue denied ITC citing § 17(5)(d). The Orissa High Court ruled in Safari’s favour — allowing ITC on the ground that the mall qualified as “plant” (a structure used in the course of business).
Supreme Court held:

The Orissa High Court ruled in Safari’s favour — allowing ITC on the ground that the mall qualified as “plant” (a structure used in the course of business).
Supreme Court held:
- Section 17(5)(c) and (d) are constitutionally valid — Parliament has the power to restrict ITC as fiscal policy
- Section 16(4)’s time limit is also valid
- The word “plant” in “plant or machinery” must be interpreted using a functionality test — does the structure function as a plant in the business? If a building is the very apparatus by which the business operates (like a cold storage for a refrigeration company, or a dry dock for a ship repair company), it may qualify as “plant”
- Remanded the individual case back to the High Court to apply the functionality test to Safari’s mall
12.3 Finance Act 2025 — Retrospective Amendment (w.e.f. 1 July 2017)
⚠️ Finance Act 2025, Section 119 — Amendment to § 17(5)(d) — RETROSPECTIVE FROM 1 JULY 2017:
The Finance Act 2025, enacted after the 55th GST Council recommendation, amended Section 17(5)(d) by replacing the words “plant or machinery” with “plant and machinery.”
The single word change — from “or” to “and” — has enormous legal consequences:
• “Plant or machinery”: A structure could qualify if it was a “plant” OR if it was “machinery” — giving flexibility
• “Plant and machinery”: A structure must be BOTH plant AND machinery to qualify — far harder to satisfy
Effective date: The amendment was made retrospective from 1 July 2017 — the date GST was introduced. This effectively nullifies the Safari Retreats judgment, all related High Court rulings that followed it, and any ITC claims made based on that interpretation — for the entire history of GST.
CBIC notified 1 October 2025 as the enforcement date for this and other Finance Act 2025 amendments to the CGST Act.

12.4 Review Petition Dismissed — Supreme Court (22 May 2025)
⚖️ Safari Retreats Review Petition — Supreme Court (22 May 2025):
After the retrospective amendment nullified their victory, Safari Retreats filed a review petition before the Supreme Court. On 22 May 2025, the Supreme Court dismissed the review petition — upholding Parliament’s authority to make retrospective amendments.
Current position: The legislative amendment stands. The Safari Retreats interpretation of “plant or machinery” allowing ITC on commercial buildings built for renting is effectively overruled.

12.5 Agratas Energy AAR Ruling (November 2025) — Post-Amendment Clarity
⚖️ Agratas Energy Storage Solutions Pvt. Ltd. v. ARA, Gujarat (AAR, November 2025):
Agratas (a Tata Sons subsidiary) sought ITC on construction costs for a battery cell manufacturing factory on a 50-year leased plot in GIDC, Ahmedabad. They argued: (a) the factory building qualifies as “plant and machinery,” (b) the land lease itself should get ITC.
AAR held: With the Finance Act 2025 retrospective amendment replacing “plant or machinery” with “plant and machinery,” the earlier Safari Retreats reasoning no longer applies. The construction is of an immovable property — ITC is blocked. Even ITC on land lease payments incurred during construction cannot be claimed — if the purpose of the lease is tied to construction of the immovable property, § 17(5)(d) applies.
Lesson for large industrial projects: Even factory buildings, warehouses, and manufacturing facilities — if constructed as immovable property — cannot claim ITC on construction costs under the current amended law.

12.6 What “Plant and Machinery” Means Now
The Explanation to Section 17 of the CGST Act defines “plant and machinery” as:
Definition — “Plant and Machinery” (Explanation to § 17, CGST Act):
Apparatus, equipment, and machinery fixed to earth by foundation or structural support that are used for making outward supply of goods or services or both, and includes such foundation and structural support but EXCLUDES:
Apparatus, equipment, and machinery fixed to earth by foundation or structural support that are used for making outward supply of goods or services or both, and includes such foundation and structural support but EXCLUDES:
- Land, building or any other civil structure
- Telecommunication towers
- Pipelines laid outside the factory premises
| Asset | Plant and Machinery? | ITC on Construction? |
|---|---|---|
| Manufacturing equipment (lathe, press, CNC machine) | ✅ Yes — apparatus/equipment | ✅ ITC available on supply/installation |
| Factory building (structure housing equipment) | ❌ No — civil structure excluded | ❌ Blocked (§ 17(5)(d)) |
| Cold storage unit (functional refrigeration system) | Contested — depends on whether classified as apparatus or civil structure | Uncertain — seek specific AAR/circular guidance |
| Telecommunication tower | ❌ Excluded explicitly | ❌ Blocked |
| Pipeline inside factory | ✅ Generally Yes | ✅ ITC available (within factory premises) |
| Pipeline outside factory | ❌ Excluded explicitly | ❌ Blocked |
| Solar panel installation on rooftop | ✅ Equipment/apparatus | ✅ ITC on solar panels and installation service |
| Office building being constructed | ❌ Civil structure | ❌ Blocked |
| Shopping mall built for renting | ❌ Civil structure (post-Finance Act 2025) | ❌ Blocked (Safari Retreats reversal) |
13. Personal Consumption & Non-Business Use — Section 17(5)(e)
ITC is blocked on goods or services received for personal consumption. This applies when goods/services are used by the proprietor, partners, directors, or employees for personal — non-business — purposes.
- ✗ Mobile phone purchased by company for director’s personal use
- ✗ Furniture for residential quarters of employees
- ✗ Groceries or personal items bought by company for proprietor’s family
- ✓ Mobile phone for sales team (business use) — ITC allowed
- ✓ Laptop for employees doing company work — ITC allowed
When goods/services serve both business and personal purposes (e.g., a company phone used for personal calls too), Rule 42 applies — ITC must be proportionately reversed based on the ratio of exempt/personal use to total use. Maintain usage logs for such assets.
14. Lost, Stolen, Destroyed & Written-Off Goods — Section 17(5)(f)
ITC is blocked on goods that are:
- Lost — goods that go missing from inventory
- Stolen — theft at warehouse, in transit, etc.
- Destroyed — fire, flood, natural disasters
- Written off — obsolete, expired, damaged beyond use
- Disposed of as gifts or free samples — samples given to customers/dealers
Practical compliance requirement:
When such events occur, the ITC already claimed on these goods must be reversed in GSTR-3B Table 4(B)(2). If ITC was not yet claimed, it cannot be claimed. If already availed — reverse immediately in the tax period of discovery/write-off.
Documentation required: FIR (for theft), insurance claim documents (for fire/flood), stock-taking records (for losses), write-off entries in books with board approval. GST audits specifically look for ITC reversal on written-off stocks.

Free samples — the marketing cost trap: Pharmaceutical companies giving drug samples, FMCG companies distributing free trial products, tech companies giving trial hardware — ALL must reverse ITC on these free samples. The cost of the ITC reversal is effectively part of the marketing cost. Budget for this when planning sample distribution campaigns.
15. Composition Tax, Section 74 Penalties — Section 17(5)(g)
ITC is blocked on:
- Tax paid under the composition scheme (Section 10) — composition levy is paid by the dealer and cannot be credited anywhere
- Tax paid under Section 74 — demands raised in cases involving fraud, suppression, or wilful misstatement. The penalty/demand tax cannot generate ITC
- Tax paid under Section 129 — tax paid at the time of detention and release of goods/vehicles
- Tax paid under Section 130 — tax paid at the time of confiscation proceedings
Policy rationale: Tax paid as a consequence of evasion or non-compliance (§ 74, 129, 130) should not generate ITC — that would effectively reward evasion. Similarly, composition tax paid by small dealers has no ITC chain to create.
16. Employee Benefits — What’s Blocked, What’s Allowed
Employee-related expenditure is one of the most complex areas — some attract blocked ITC, some are fully eligible, some are partially eligible:
| Expense | ITC Status | Basis |
|---|---|---|
| Employee health insurance premium (mediclaim) | ❌ Blocked | § 17(5)(b)(iv) — health insurance blocked |
| Group term life insurance (pre-Sept 2025) | ❌ Blocked | § 17(5)(b)(iv) — life insurance blocked |
| Group term life insurance (post-Sept 2025) | N/A — EXEMPT | Life insurance now GST-exempt — no GST, no ITC issue |
| ESIC / PF contributions | N/A | Not GST — no ITC angle |
| Employee uniforms (required for business) | ✅ Allowed | Business purpose; not personal use; not in blocked list |
| Safety equipment (helmets, boots, gloves) | ✅ Allowed | Business/statutory requirement; not blocked |
| Mobile phones provided to sales team | ✅ Allowed | Business tool — ITC allowed; partial reversal if personal use |
| Office canteen (factory < 250 workers) | ❌ Blocked | § 17(5)(b)(i) — food blocked; not “obligatory” below 250-worker threshold |
| Office canteen (factory ≥ 250 workers, Factories Act obligation) | Contested | CBIC Circular 172 allows it if obligatory; but AAR rulings vary |
| Annual company trip for employees (vacation) | ❌ Blocked | § 17(5)(b)(v) — travel benefit on vacation |
| Business conference travel for employees | ✅ Allowed | Business travel, not vacation — outside § 17(5) scope |
| Car provided to employee (seating ≤ 13) | ❌ Blocked | § 17(5)(a) — motor vehicle blocked |
| Club membership for employee | ❌ Blocked | § 17(5)(b)(iii) — club membership explicitly blocked, no exception |
17. The 180-Day Payment Rule — Reversal Under Section 16(2) / Rule 37
This is one of the most operationally challenging ITC reversal requirements — and one of the most frequently missed by businesses that operate on long credit cycles. The rule is simple: if you don’t pay your supplier within 180 days of the invoice date, you must reverse the ITC you claimed on that invoice.
Section 16(2)(b), CGST Act 2017 read with Rule 37, CGST Rules:
A registered person shall reverse the ITC availed in respect of any invoice or debit note if the value of supply (goods/services cost) AND the tax thereon (GST amount) are not paid to the supplier within 180 days from the date of the invoice.
The reversed amount must be added to the output tax liability in the return for the month following the month in which the 180-day period expires.
A registered person shall reverse the ITC availed in respect of any invoice or debit note if the value of supply (goods/services cost) AND the tax thereon (GST amount) are not paid to the supplier within 180 days from the date of the invoice.
The reversed amount must be added to the output tax liability in the return for the month following the month in which the 180-day period expires.
The 180-Day Timeline
| Event | Date/Deadline |
|---|---|
| Invoice issued by supplier | Day 0 — clock starts |
| ITC claimed by recipient in GSTR-3B | Any month within the time limit |
| Last date to pay supplier (value + GST) | Day 180 from invoice date |
| If not paid by Day 180 — ITC reversal due | In GSTR-3B for the month following expiry of 180-day period |
| Payment eventually made after Day 180 | Re-avail ITC in the GSTR-3B of the month of actual payment |
Critical Points on the 180-Day Rule
- Both value AND tax must be paid: Paying only the base amount without the GST component — or only the GST without the base — does not satisfy the 180-day condition. Both must be paid.
- Applies to goods AND services: Unlike the Service Tax era where a 3-month rule applied only to services, GST’s 180-day rule covers both goods and services.
- Partial payment — partial retention: If you pay 60% of the invoice value (including proportionate GST) within 180 days, you can retain 60% of the ITC and must reverse only the remaining 40%.
- Interest on late reversal: If you don’t reverse within the prescribed period, interest at 18% p.a. runs from the date ITC was originally availed to the date of reversal — not from Day 180.
- Re-availment is permanent: Once you pay the supplier (even after 180 days), you can re-claim the ITC. The reversal is temporary.
180-Day Rule — Worked Example
Scenario: Company ABC receives a services invoice from XYZ Consultants for ₹5 lakh + 18% GST (₹90,000). Invoice date: 1 April 2025. ABC claims ITC of ₹90,000 in April 2025 GSTR-3B.
| Date | Event | Action |
|---|---|---|
| 1 April 2025 | Invoice date | ITC of ₹90,000 claimed in April 2025 GSTR-3B |
| 28 September 2025 | 180-day deadline (180 days from 1 Apr) | ABC has NOT paid XYZ. Must reverse ITC. |
| 20 October 2025 | GSTR-3B for September due (Table 4B2) | Reverse ₹90,000 ITC + pay interest at 18% p.a. from April to October = ~₹90,000 × 18% × 6/12 = ₹8,100 interest |
| 15 November 2025 | ABC finally pays XYZ ₹5.9L | Re-avail ₹90,000 ITC in November 2025 GSTR-3B (Table 4A5) |
ABC ends up with ₹8,100 in irrecoverable interest cost purely due to delayed payment. For large-value invoices — especially in infrastructure, manufacturing, and long-credit-cycle businesses — this interest cost compounds significantly.
⚠️ Policy critique (December 2025):
A Lexology analysis from December 2025 noted that the 180-day rule was designed to curb fraudulent ITC on fake invoices — but has become a blanket compliance burden on genuine businesses with normal commercial credit cycles (60–120 days). In sectors like infrastructure, government contracting, and pharmaceuticals with distributor credit, the 180-day rule creates repeated reversal-re-availment cycles even for perfectly legitimate transactions. Industry bodies are seeking either exemption for B2B industries with standard credit terms or a shorter re-availment period without interest obligation. As of May 2026, no amendment has been made — the rule remains in its current form.

18. Rule 37A — Reversal When Supplier Doesn’t File GSTR-3B
Rule 37A (inserted by CGST Amendment Rules, 2022) adds another reversal obligation: if your supplier claimed to have paid GST but actually did not file their GSTR-3B (and hence did not pay tax to the government), you must reverse the ITC you took on that supplier’s invoice.
Rule 37A, CGST Rules 2017 — Trigger:
If a registered person has availed ITC on an invoice that appears in their GSTR-2B, and the corresponding supplier does NOT file GSTR-3B for that period by 30 September of the following financial year — the recipient must reverse that ITC by 30 November of that year.
If the supplier subsequently files their GSTR-3B and pays the tax, the recipient can re-avail the ITC in the return for the month in which the supplier’s GSTR-3B is filed.

If the supplier subsequently files their GSTR-3B and pays the tax, the recipient can re-avail the ITC in the return for the month in which the supplier’s GSTR-3B is filed.
Rule 37A Compliance Timeline
| Event | Deadline |
|---|---|
| Supplier must file GSTR-3B (e.g., for FY 2025-26 invoices) | By 30 September 2026 |
| If supplier hasn’t filed by 30 Sept — recipient must reverse ITC | By 30 November 2026 (in Table 4B2 of GSTR-3B) |
| Interest if reversal not done by 30 November | 18% p.a. from date of original ITC availing |
| Supplier files GSTR-3B after 30 Sept (even in 2027 or later) | Recipient may re-avail ITC in the month supplier files |
| Section 16(4) time limit | Re-availment must be within the ITC time limit — 30 November of the relevant FY or GSTR-9 date |
Practical supplier monitoring practice:
Download your GSTR-2B every month. For every invoice in your GSTR-2B, the system confirms the supplier filed GSTR-1 (so the invoice is reflected). But Rule 37A is about the supplier filing GSTR-3B (actually paying the tax). The GST portal should ideally flag mismatches — but practical tracking requires:

- Including a contractual clause requiring suppliers to maintain GST compliance and share return filing proof quarterly
19. Rule 42 — Complete Mixed-Use ITC Reversal Formula
When a business makes both taxable and exempt (or non-business) supplies, ITC on common inputs and input services cannot be fully claimed. Rule 42 provides the precise formula to calculate the reversal.
Step 1: Classify All ITC into Four Categories
| Category | What It Covers | Treatment |
|---|---|---|
| T1 (Exclusively blocked) | ITC on goods/services blocked under Section 17(5) — cars, food, construction, etc. | Reverse entirely. Cannot be claimed. |
| T2 (Exclusively for exempt supplies) | Inputs used exclusively to make exempt outward supplies | Reverse entirely. |
| T3 (Exclusively for non-business / personal use) | Inputs used entirely for personal purposes | Reverse entirely. |
| T4 (Exclusively for taxable supplies including zero-rated) | Inputs 100% used for taxable or zero-rated (export) supplies | Full ITC available — no reversal. |
| T5 (Common credit) | Remaining ITC — inputs used for both taxable AND exempt/personal supplies | Apply Rule 42 formula below. |
Step 2: Apply the Rule 42 Reversal Formula
Rule 42 Formula for Common ITC (T5):
D1 = T5 × (E + N) / F
Where:
T5 = Total common ITC (after excluding T1, T2, T3, T4)
E = Aggregate value of exempt supplies during the tax period
N = Aggregate value of non-business supplies
F = Total aggregate turnover in the state (all supplies)
D2 = 5% × T5 (flat reversal for personal/non-business use — an absolute reversal)
Total ITC reversal = D1 + D2
Net ITC available from common pool = T5 − D1 − D2
D1 = T5 × (E + N) / F
Where:
T5 = Total common ITC (after excluding T1, T2, T3, T4)
E = Aggregate value of exempt supplies during the tax period
N = Aggregate value of non-business supplies
F = Total aggregate turnover in the state (all supplies)
D2 = 5% × T5 (flat reversal for personal/non-business use — an absolute reversal)
Total ITC reversal = D1 + D2
Net ITC available from common pool = T5 − D1 − D2
Rule 42 Calculation — Insurance Company with Mixed Supplies
ABC Insurance Ltd. offers both taxable (general insurance) and exempt (life insurance) products. Monthly details:
| Parameter | Amount |
|---|---|
| Total ITC in GSTR-2B this month | ₹10,00,000 |
| T1 — Blocked (vehicles, food) | ₹1,50,000 → Reverse entirely |
| T2 — Exclusively for life insurance (exempt) | ₹1,00,000 → Reverse entirely |
| T4 — Exclusively for general insurance (taxable) | ₹3,00,000 → Full ITC available |
| T5 — Common ITC | ₹10L − ₹1.5L − ₹1L − ₹3L = ₹4,50,000 |
| Exempt turnover (life insurance premium) | ₹40,00,000 |
| Total turnover | ₹1,00,00,000 |
| D1 = ₹4,50,000 × (₹40L / ₹1 crore) | ₹1,80,000 → Reverse |
| D2 = 5% × ₹4,50,000 | ₹22,500 → Reverse |
| Net ITC from common pool = ₹4,50,000 − ₹1,80,000 − ₹22,500 | ₹2,47,500 |
| Total monthly ITC available = T4 + Net T5 = ₹3,00,000 + ₹2,47,500 | ₹5,47,500 |
Annual Reconciliation of Rule 42
The monthly Rule 42 calculation uses a provisional ratio based on the preceding year’s exempt/taxable split. At the end of each financial year, the actual annual ratio must be calculated and the cumulative reversal adjusted:
- If actual exempt ratio > provisional ratio → Additional reversal required (report in March GSTR-3B and GSTR-9)
- If actual exempt ratio < provisional ratio → Excess reversal can be re-availed (credit back to Electronic Credit Ledger)
- This annual true-up must also be reflected in GSTR-9 (Annual Return)
⚠️ Most businesses with mixed supply skip the annual true-up. Monthly Rule 42 reversal based on provisional ratios + no annual adjustment = either under-reversal (tax demand in audit) or over-reversal (leaving credit unclaimed). Annual reconciliation is not optional — it is required under Rule 42(2) and reported in GSTR-9.
20. Rule 43 — Capital Goods ITC Reversal Methodology
For capital goods (plant, machinery, equipment, IT assets) used for making both taxable and exempt supplies, ITC is handled differently from regular inputs:
Step 1: Classify Capital Goods
| Category | Treatment |
|---|---|
| Capital goods exclusively for non-business / personal use | No ITC — fully blocked |
| Capital goods exclusively for exempt supplies | No ITC — fully reversed |
| Capital goods exclusively for taxable supplies | Full ITC available immediately |
| Capital goods used for both taxable + exempt supplies | Apply Rule 43 methodology below |
Step 2: The Rule 43 Calculation Mechanism
Rule 43 — Capital Goods Mixed Use:
Total ITC on capital good = Tc
Monthly credit = Tc / 60 (ITC spread over 60 months = 5 years)
For each month:
ITC to reverse = (Tc / 60) × D1 ratio from Rule 42 for that month
(Where D1 ratio = Exempt turnover / Total turnover for the month)
Net monthly ITC from capital good = (Tc / 60) × (1 − D1 ratio)
Total ITC on capital good = Tc
Monthly credit = Tc / 60 (ITC spread over 60 months = 5 years)
For each month:
ITC to reverse = (Tc / 60) × D1 ratio from Rule 42 for that month
(Where D1 ratio = Exempt turnover / Total turnover for the month)
Net monthly ITC from capital good = (Tc / 60) × (1 − D1 ratio)
Rule 43 — Machinery Used for Both Taxable and Exempt Supplies
XYZ Pharma buys a ₹60 lakh manufacturing machine. ITC = ₹6 lakh (10% GST). Machine used for both taxable drugs and exempt medicines (50:50 on average).
| Item | Calculation | Amount |
|---|---|---|
| Monthly ITC from machine | ₹6,00,000 / 60 months | ₹10,000/month |
| Exempt turnover ratio (monthly) | 50% (₹50L exempt / ₹1 crore total) | 50% |
| Monthly reversal | ₹10,000 × 50% | ₹5,000/month reversed |
| Monthly ITC retained | ₹10,000 − ₹5,000 | ₹5,000/month available |
| Over 60 months — total ITC available | ₹5,000 × 60 | ₹3,00,000 (50% of ₹6L total ITC) |
If the exempt ratio changes (say Pharma’s exempt supply reduces to 30%), the Rule 43 monthly reversal adjusts accordingly — making Rule 43 a dynamic, month-by-month calculation throughout the asset’s 5-year period.
Capital Goods Transferred, Sold or Written Off
- If capital goods are sold/transferred — ITC for remaining months (60 minus months used) must be reversed in the month of disposal
- If capital goods are destroyed / written off — ITC for remaining useful life must be reversed per Rule 43 + Section 17(5)(f)
- If capital goods are converted from taxable to exempt use — prospective Rule 43 reversal applies for the remaining months
21. Rule 44 — ITC Reversal on Registration Cancellation & Switching to Composition
On Cancellation of GST Registration
When GST registration is cancelled (voluntary or forced), the registered person must reverse ITC on all goods/assets held on the date of cancellation:
Rule 44, CGST Rules — ITC Reversal on Cancellation:
A registered person whose registration is cancelled must reverse ITC on:
(a) Inputs held in stock (raw materials, goods for resale)
(b) Inputs contained in semi-finished and finished goods in stock
(c) Capital goods and plant & machinery — at the higher of:
(i) ITC taken reduced by 5% per quarter from date of purchase, OR
(ii) Tax on transaction value (current market value) of such capital goods
A registered person whose registration is cancelled must reverse ITC on:
(a) Inputs held in stock (raw materials, goods for resale)
(b) Inputs contained in semi-finished and finished goods in stock
(c) Capital goods and plant & machinery — at the higher of:
(i) ITC taken reduced by 5% per quarter from date of purchase, OR
(ii) Tax on transaction value (current market value) of such capital goods
This reversal is reported in GSTR-10 (Final Return) which must be filed within 3 months of cancellation or the cancellation order date, whichever is earlier.
On Switching to Composition Scheme
A taxpayer switching from regular scheme to composition scheme must reverse ITC on stock held on the date of opting in — using Form ITC-03 (within 60 days of opting). Refer to Blog 3 on Composition Scheme for the full ITC-03 process.
On Goods Becoming Exempt
If goods that were earlier taxable become exempt (due to a new notification), the registered supplier must reverse ITC on stock of such goods held on the date the exemption takes effect. The reversal must be done in the GSTR-3B for the month the exemption applies.
22. GSTR-3B Table 4 — How to Report Every Type of ITC Reversal
GSTR-3B Table 4 is the central point for all ITC reporting. Getting this right is critical — incorrect Table 4 entries are the primary source of GST scrutiny notices.
| Table | What Goes Here | Examples |
|---|---|---|
| Table 4(A)(1) | ITC available — Imports of goods | IGST paid at customs on imported goods |
| Table 4(A)(2) | ITC available — Imports of services | IGST paid under RCM on foreign services (Google Ads, AWS) |
| Table 4(A)(3) | ITC available — Inward supplies under RCM (domestic) | ITC on GTA RCM, lawyer RCM, director sitting fees RCM |
| Table 4(A)(4) | ITC available — Input Service Distributor (ISD) | ITC distributed by HO to branches via ISD mechanism |
| Table 4(A)(5) | ITC available — All other ITC (domestic B2B purchases) | Regular purchase invoices appearing in GSTR-2B |
| Table 4(B)(1) ← REVERSAL | PERMANENT reversals — cannot be re-availed | Section 17(5) blocked credits (cars, food, construction), Rule 42 reversals, Rule 43 reversals |
| Table 4(B)(2) ← REVERSAL | TEMPORARY reversals — can be re-availed later | Rule 37 (180-day non-payment), Rule 37A (supplier non-filing), Section 16(2)(b) (goods not received), Section 16(2)(c) (supplier non-payment) |
| Table 4(C) | Net ITC available = 4(A) minus 4(B) | Auto-calculated — credited to Electronic Credit Ledger |
| Table 4(D)(1) | Re-claimed ITC previously reversed under 4(B)(2) | ITC re-availed after 180-day payment; after supplier files GSTR-3B |
| Table 4(D)(2) | Ineligible ITC per GSTR-2B (informational — not affecting ECL) | Invoices in GSTR-2B that are ineligible under § 17(5) |
⚠️ Most common Table 4 error — Wrong column for reversal type:
Many businesses put ALL reversals in Table 4(B)(1). This is wrong — permanent and temporary reversals must be separated:
• Section 17(5) blocked credits → Always in 4(B)(1) — these can NEVER be re-availed
• 180-day non-payment, supplier non-filing → Always in 4(B)(2) — these can be re-availed later
Misclassifying a temporary reversal as 4(B)(1) means you’ve permanently written off ITC that you could have recovered — a real financial loss.

| ITC on Google Ads RCM (import of services) | ₹54,000 | 4(A)(3) |
| ITC on company car purchase (blocked § 17(5)(a)) | ₹3,20,000 | 4(B)(1) → Permanent reversal |
| ITC on office canteen catering (blocked § 17(5)(b)) | ₹45,000 | 4(B)(1) → Permanent reversal |
| ITC on invoice unpaid >180 days (vendor C) | ₹28,000 | 4(B)(2) → Temporary reversal |

| Net ITC credited to ECL (Table 4C) | ₹3,41,000 | 8L + 54k − 3.2L − 45k − 28k − 1.2L |
23. Re-Availment of Reversed ITC — What Can Come Back
Not all reversals are permanent. This table summarises which reversed ITC can be re-claimed and under what conditions:
| Reversal Reason | Can Re-Avail? | Condition for Re-Availment | GSTR-3B Table |
|---|---|---|---|
| 180-day non-payment (Rule 37) | ✅ Yes | Pay supplier the value + GST amount | Table 4(D)(1) |
| Supplier non-filing of GSTR-3B (Rule 37A) | ✅ Yes | Wait for supplier to file their GSTR-3B; ITC appears in your GSTR-2B | Table 4(D)(1) |
| Goods not received (§ 16(2)(b)) | ✅ Yes | Actual receipt of goods/services | Table 4(D)(1) |
| Rule 42 reversal (provisional monthly) | ✅ Partial | Annual true-up — if actual exempt ratio less than provisional | Table 4(D)(1) / GSTR-9 |
| Rule 43 reversal (capital goods) | ✅ Partial | Annual true-up — if exempt ratio decreases | GSTR-9 adjustment |
| Section 17(5) blocked credits | ❌ Never | Cannot be re-availed under any circumstance | N/A |
| ITC on lost/stolen/destroyed goods (§ 17(5)(f)) | ❌ Never | Once goods are lost — ITC is gone | N/A |
| ITC on composition levy (§ 17(5)(g)) | ❌ Never | Not reclaimable | N/A |
| ITC reversed on switching to composition (ITC-03) | ✅ Partial | Upon exit from composition — file ITC-01 for opening stock ITC | ITC-01 |
Key principle — permanent vs temporary:
Section 17(5) reversals are PERMANENT — they go to Table 4(B)(1) and can never return. Rule 37, Rule 37A, and Section 16(2)(b)/(c) reversals are TEMPORARY — they go to Table 4(B)(2) and can come back in Table 4(D)(1). Rule 42/43 reversals sit in between — permanent for the period but subject to annual true-up adjustment.

24. Banking Companies, Financial Institutions & NBFCs — Special 50% ITC Rule Rule 38, CGST Rules
Banks, NBFCs, and financial institutions face a unique ITC restriction unlike any other sector. Due to the complexity of separating taxable financial services from exempt services, Rule 38 provides a simplified option:
Rule 38, CGST Rules — Banking and Financial Institutions:
A banking company or a financial institution (including NBFC) engaged in supplying services by way of accepting deposits, extending loans, or advances may avail ITC to the extent of 50% of the eligible ITC on all inputs and input services in the relevant month and the rest shall lapse.
This is an optional flat 50% reversal. The bank can alternatively apply Rule 42 (proper apportionment based on turnover ratios) if that’s more beneficial.
A banking company or a financial institution (including NBFC) engaged in supplying services by way of accepting deposits, extending loans, or advances may avail ITC to the extent of 50% of the eligible ITC on all inputs and input services in the relevant month and the rest shall lapse.
This is an optional flat 50% reversal. The bank can alternatively apply Rule 42 (proper apportionment based on turnover ratios) if that’s more beneficial.
| Approach | Calculation | When Beneficial |
|---|---|---|
| Rule 38 — Flat 50% option | Claim only 50% of total eligible ITC; reverse 50% | When exempt supply ratio > 50% of total supplies; or when calculation complexity is a concern |
| Rule 42 — Turnover-based apportionment | Calculate exact exempt ratio; reverse proportionately | When actual exempt ratio < 50% — retains more ITC |
Once Rule 38 (50%) option is chosen for a year, it cannot be changed mid-year. Banks and NBFCs must evaluate at the start of each financial year which method will result in better ITC retention and commit to it. Large banks with significant retail liability (exempt deposits) vs significant taxable fee income need to model both options carefully.
25. Common ITC Reversal Mistakes and How to Fix Them
| Mistake | Risk | Fix |
|---|---|---|
| Not tracking 180-day payment deadlines for supplier invoices | Interest on reversal from day of ITC claim; demand in audit | Maintain an invoice ageing register; set 150-day alerts for all unpaid supplier invoices |
| Putting 180-day reversal in Table 4(B)(1) instead of 4(B)(2) | Permanently forfeiting re-claimable ITC | All Rule 37 reversals go to 4(B)(2); re-avail in 4(D)(1) after payment |
| Not doing Rule 42 calculation monthly (doing it only annually) | Annual lump reversal creates interest liability; GSTR-9 mismatch | Calculate Rule 42 every month; report in Table 4(B)(1); adjust at year-end |
| Not doing annual Rule 42/43 true-up in GSTR-9 | Discrepancy between GSTR-3B aggregate and GSTR-9; notice | Run annual ratio calculation; report excess/shortfall in GSTR-9 Tables 7 and 12 |
| Not reversing ITC on stock when switching to composition | ITC-03 non-filing penalty; demand for un-reversed ITC | File ITC-03 within 60 days of opting for composition with accurate stock list |
| Not reversing ITC on write-offs in the right month | Interest from date of write-off to date of reversal | Reverse ITC in the same GSTR-3B period as the stock is written off in books |
| Banking company defaulting to Rule 42 when Rule 38 (50%) gives more ITC | Under-claiming ITC; overpaying GST | Annual modelling exercise; opt for most beneficial method by April |
| Not re-availing ITC after supplier files pending GSTR-3B (Rule 37A) | Leaving money on table — ITC lost through inaction | Monitor supplier filing status quarterly; re-avail in Table 4(D)(1) once they comply |
The ITC Reversal Reconciliation — A Business-Critical Annual Exercise:
Every business with any exempt supplies, blocked credit categories, or long credit cycles should conduct an annual ITC reversal reconciliation before filing GSTR-9. This involves:
Every business with any exempt supplies, blocked credit categories, or long credit cycles should conduct an annual ITC reversal reconciliation before filing GSTR-9. This involves:
- Listing all reversals done in GSTR-3B across all months (4(B)(1) + 4(B)(2))
- Recalculating Rule 42 on annual turnover ratios vs monthly provisional ratios
- Identifying any missed reversals (to proactively correct before audit)
- Identifying over-reversals (to re-avail ITC that was unnecessarily surrendered)
- Reconciling with GSTR-9 disclosure and audit report (GSTR-9C for >₹5 crore turnover)
26. GSTR-2B and ITC Matching — Current Framework
From January 2022, ITC claims must be matched with GSTR-2B — the auto-generated, system-calculated ITC statement. Key rules:
- ITC can only be claimed on invoices/debit notes that appear in your GSTR-2B
- No provisional ITC — all ITC must be GSTR-2B-matched before claiming
- If a supplier’s invoice doesn’t appear in your GSTR-2B (supplier hasn’t filed GSTR-1), you cannot claim ITC — even if you hold the invoice and received the goods/services
- Rule 36(4): No buffer — 0% provisional ITC above GSTR-2B (the old 5% provisional buffer was removed)
Supplier non-compliance = your ITC loss:
If your supplier doesn’t file GSTR-1 on time, their invoices don’t appear in your GSTR-2B. You lose ITC on those invoices — at least temporarily. Remedy: (1) Pay only after verifying supplier’s GSTR-1 filing history, (2) Include a contract clause making payment subject to GST compliance verification, (3) Follow up with non-compliant suppliers immediately after the 11th of every month.

27. Common ITC Mistakes That Attract GST Notices
| Mistake | Risk | Prevention |
|---|---|---|
| Claiming ITC on car purchase (≤13 seats) | Demand + 18% interest + penalty | Remove all motor vehicle credits from GSTR-3B before filing |
| Claiming ITC on office construction materials | Large demand for multi-year construction | Segregate construction invoices — no ITC on civil structure |
| Not reversing ITC on free samples sent to dealers | Demand for unreverted ITC | Monthly tracking of sample distributions; reverse in same GSTR-3B |
| ITC on indoor canteen food above the ₹25,000/month threshold for non-obligatory | Demand for blocked food ITC | Segregate employee meal costs; verify Factories Act applicability |
| Claiming ITC on health insurance after Finance Act 2024 | Demand for blocked health insurance ITC | Health insurance ITC remains blocked — verify each year’s notification |
| Not doing Rule 42 reversal for exempt supplies | Annual GST-9 mismatch; demand | Run Rule 42 calculation monthly; finalize in GSTR-9/9C |
| Claiming ITC on construction (Safari Retreats expectation) | Demand for the entire ITC claimed based on reversed judgment | Post-Finance Act 2025, no ITC on civil construction — reverse any such claims |
| ITC on invoices not appearing in GSTR-2B | Reversal demand in scrutiny | Match GSTR-2B monthly before claiming ITC in GSTR-3B |
| ITC claimed after Section 16(4) time limit | Permanent disallowance; demand | Track invoice age; claim within same FY or by 30 November of next FY |
28. Case Studies
Case 1: IT Company — Identifying Blocked Credits in Annual ITC
TechHub Pvt. Ltd., Bengaluru. Annual GST ITC as per GSTR-2B: ₹85 lakh. After GCA’s ITC audit, blocked credits identified:
| Expense Category | ITC Claimed | Blocked? | Reversal Required |
|---|---|---|---|
| Server racks and IT equipment | ₹40L | No — plant & machinery | ₹0 |
| Office renovation (civil work) | ₹15L | Yes — § 17(5)(d) | ₹15L |
| Employee health insurance | ₹8L | Yes — § 17(5)(b)(iv) | ₹8L |
| Employee meals / canteen vendor | ₹6L | Yes — § 17(5)(b)(i) | ₹6L |
| 3 company cars (under 13 seats) | ₹12L | Yes — § 17(5)(a) | ₹12L |
| Software licenses (vendor invoices) | ₹4L | No — input service for business | ₹0 |
| Total blocked ITC to reverse | — | — | ₹41L |
TechHub had inadvertently claimed ₹41L in blocked credits. Without the audit, this would have been flagged in a GST audit with 18% p.a. interest + penalties on the full ₹41L.
Case 2: Developer — The Safari Retreats ITC Hope and Its Reversal
Timeline for a commercial developer who built a mall worth ₹50 crore (construction cost):
| Date | Event | ITC Position |
|---|---|---|
| July 2017 – Sept 2024 | Mall under construction; GST on materials and works contract ~₹9 crore | ITC blocked under § 17(5)(d) — ₹9 crore denied |
| October 3, 2024 | Supreme Court — Safari Retreats: mall may qualify as “plant” using functionality test | Hope: ₹9 crore potentially claimable |
| February 2025 | Finance Act 2025 — “plant or machinery” → “plant and machinery” — retrospective from 1 July 2017 | Hope dashed: retrospective amendment blocks the ITC claim |
| May 22, 2025 | Supreme Court dismisses Safari Retreats review petition | Confirmed: ₹9 crore ITC permanently lost |
| November 2025 | Agratas AAR: post-amendment, even factory buildings blocked | Position settled: construction ITC blocked for immovable property |
Case 3: Pharma Company — Free Samples ITC Reversal
MedPharma Ltd. distributes 50,000 drug samples to doctors annually. Each sample costs ₹80 including 12% GST (₹8.57 GST per unit).
- Total GST on samples = 50,000 × ₹8.57 = ₹4,28,500
- ITC claimed on purchase of sample stock: ₹4,28,500
- After distribution (given free) — must reverse under § 17(5)(f): ₹4,28,500
- Net ITC available: ₹0
- Annual cost of sample distribution: Manufacturing cost + ₹4,28,500 GST (non-reclaimable)
- Many pharma companies miss this reversal — treating sample distribution like a normal sale. GST audits specifically target pharma sector for this.
29. Frequently Asked Questions
Q1. After the Safari Retreats reversal, can we claim ITC on construction of a cold storage facility (refrigeration plant)?
Cold storage is a grey area post the Finance Act 2025 amendment. The amendment blocks ITC on “immovable property” construction but retains the “plant and machinery” exception. A cold storage’s refrigeration system, compressors, and chilling apparatus may qualify as “plant and machinery” (apparatus fixed to earth for making outward supply). However, the civil structure (walls, roofing, flooring) would be blocked. The practical approach: bifurcate construction costs between the functional plant/equipment components and the civil structure. Claim ITC on equipment; block on civil. AAR rulings on cold storage specifically vary — consult GCA before taking a position.
Q2. We paid 18% GST on employee health insurance. Can we claim ITC?
No — employee health insurance is explicitly blocked under Section 17(5)(b)(iv) of CGST Act. The only exception is if your company’s outward supply is health insurance services (i.e., you are an insurance company) OR if the health insurance is mandatorily required by law (like ESIC for employees below a certain salary — but ESIC itself is not GST). For private companies voluntarily providing mediclaim, the GST paid is a cost — no ITC. This remains unchanged after the September 2025 rate rationalization. Note: Life insurance is now exempt from GST (so no GST, no ITC question for life insurance post-September 2025).
Q3. Our supplier hasn’t filed GSTR-1 for the last quarter. Can we still claim ITC on their invoices?
Not until the supplier’s invoices appear in your GSTR-2B. Under the current framework, ITC can only be claimed for invoices reflected in GSTR-2B. If the supplier files GSTR-1 late, the invoices will appear in the next available GSTR-2B. You can then claim ITC — provided your Section 16(4) time limit for that financial year has not expired. Follow up with your supplier immediately. Include a GST compliance clause in your purchase contracts — some companies withhold payment until GSTR-1 is filed, creating a financial incentive for supplier compliance.
Q4. Our company bought a 14-seater bus for employee transport. Is ITC available?
Yes. Section 17(5)(a) blocks ITC only on motor vehicles with seating capacity of 13 OR FEWER (including driver). A 14-seater bus (13 passengers + 1 driver = 14 total) does NOT fall under § 17(5)(a). ITC on the bus purchase is available. However, if you also pay for insurance and maintenance of this bus, those are also not blocked (because the asset itself is not blocked). Keep documentation of the seating capacity for audit purposes.
Q5. We are a hotel constructing new rooms. Can we claim ITC on construction materials after the Finance Act 2025?
No. The Finance Act 2025 retrospective amendment confirmed that construction of immovable property — even for commercial use like hotel rooms — is blocked under § 17(5)(d). The “plant or machinery” exception now reads “plant and machinery” — hotel rooms are civil structures, not plant and machinery. This is precisely the Safari Retreats scenario. ITC on construction materials, works contract services, and related costs for hotel room construction is completely blocked. However, ITC on furniture, equipment (kitchen equipment, elevators, HVAC systems that qualify as plant/machinery), and operational expenses (once the hotel is operational and making taxable supplies) remains available.
Q6. We wrongly claimed ITC of ₹10 lakh that was blocked. What do we do?
Reverse the credit immediately in the current GSTR-3B (Table 4B). Pay interest at 18% p.a. from the date of wrongful credit availing to the date of reversal. If you identify and self-correct before a GST notice, it significantly reduces penalty exposure — voluntary disclosure shows good faith. If the amount is large (over ₹5 lakh), consider also filing a rectified annual return (GSTR-9) to properly reflect the reversal. Do not wait for a notice — the longer you wait, the more interest accumulates. Contact GCA for precise calculation and rectification strategy.
