What Every Property Buyer, Builder & Contractor Needs to Know: A ₹1 crore under-construction flat attracts ₹3.33 lakh in GST. A landowner entering a Joint Development Agreement may owe GST on the land’s transfer rights. A civil contractor’s invoices to a developer are taxed at 18% — but the developer cannot claim that ITC. And every subcontractor, material supplier, and service provider in the construction chain has their own GST obligations. Real estate is perhaps the most multi-layered GST sector — this guide breaks it down for every stakeholder from buyer to builder to contractor.

1. What Attracts GST in Real Estate — and What Does Not
| Transaction | GST Applicable? | Legal Basis |
|---|---|---|
| Sale of under-construction flat/apartment to buyer | ✅ Yes | Schedule II Entry 5(b) — deemed supply of service |
| Sale of completed / ready-to-move flat (OC received before sale) | ❌ No GST | Para 5, Schedule II — completed building excluded |
| Sale of land | ❌ No GST | Schedule III Entry 5 — not a supply |
| Resale of flat by individual to another individual | ❌ No GST | Not a business activity; not supply under GST |
| Works contract services by contractor to developer | ✅ Yes — 18% | NN 11/2017-CT(R); post-Sept 2025 rate |
| Transfer of Development Rights (TDR) by landowner | ✅ Yes (RCM) | NN 13/2017-CT(R), Entry 5C; developer pays RCM |
| Long-term lease of land (≥30 years) to developer | ✅ Yes (RCM) | NN 13/2017-CT(R); developer pays 18% RCM |
| Renting of completed commercial property | ✅ Yes — 18% | Taxable service; ITC available to tenant (registered) |
| Renting of residential property for residential use | ❌ Exempt | NN 12/2017-CT(R) — residential let out for residential use |
| Pure labour contract for PMAY (EWS/LIG housing) | ❌ Exempt | NN 12/2017-CT(R) Entry 10 |
The Completion Certificate Rule — Most Important Point for Buyers:
GST is charged ONLY on under-construction properties. The moment a builder obtains an Occupancy Certificate (OC) / Completion Certificate (CC) from the local authority, the property is legally “complete” — and any sale after that point is not subject to GST. Buyers who purchase ready-to-move flats with CC/OC in hand pay zero GST — only stamp duty and registration charges apply.

2. Key Definitions
Promoter / Developer § 2(zk), RERA Act / GST Notifications
A person who constructs or develops a real estate project for sale to buyers. Under GST, the promoter is the registered taxable person responsible for charging and depositing GST on sales of under-construction units.
Affordable Housing NN 03/2019-CT(R) and NN 04/2019-CT(R)
A residential unit qualifies as “affordable housing” for the 1% GST rate ONLY if BOTH conditions are met:
| City Type | Carpet Area Condition | Value Condition |
|---|---|---|
| Metropolitan cities (Bengaluru, Chennai, Delhi NCR, Hyderabad, Kolkata, Mumbai MMR, Pune, Ahmedabad) | Carpet area ≤ 60 sq. metres | Value (total consideration) ≤ ₹45 lakh |
| Non-metropolitan cities (all other cities/towns) | Carpet area ≤ 90 sq. metres |
Pune and Ahmedabad added as metro cities (55th GST Council recommendation, effective from Tax Year 2026-27): Earlier, only Bengaluru, Chennai, Delhi NCR, Hyderabad, Kolkata, and Mumbai MMR were metros for this purpose. Pune and Ahmedabad were added, meaning more flats in these cities now qualify under the stricter 60 sqm / ₹45L threshold for affordable housing classification.
Completion Certificate / Occupancy Certificate
A document issued by the local authority (municipal corporation, development authority) certifying that construction is complete and compliant with approved plans. Once issued, the property is legally “complete” — not under construction. This certificate is the GST trigger point: sales before OC = taxable; sales after OC = not taxable.
Carpet Area vs Super Built-Up Area
GST notifications use carpet area (net usable floor area, excluding walls) for the affordable housing definition — not super built-up area or built-up area. A flat with 70 sqm super built-up area may well have ≤60 sqm carpet area and qualify as affordable.
3. GST on Under-Construction Residential Properties — Current Rates
3.1 Affordable Housing — 1% Without ITC NN 03/2019-CT(R)
Under-construction residential units meeting the affordable housing criteria are taxed at 1% GST (0.5% CGST + 0.5% SGST) with no ITC for the developer.
- Rate applies to the entire project if it qualifies as an affordable housing project under the notifications
- Developer cannot claim ITC on materials, works contract services, or any other inputs used in the project
- This rate is applied to the consideration payable for the under-construction unit, after the deemed 1/3 land deduction
3.2 Non-Affordable Residential Housing — 5% Without ITC NN 04/2019-CT(R)
All other under-construction residential units (not meeting affordable housing criteria) are taxed at 5% GST (2.5% CGST + 2.5% SGST) with no ITC for the developer.
Why no ITC for developers? The 1% and 5% rates are under a special composition-like scheme for real estate developers (not the general scheme). In exchange for these reduced rates, developers forego ITC. The government’s intention is to keep residential property prices lower — lower headline rates help buyers even though developers absorb the input tax as a cost. Post-56th Council (Sept 2025), these rates remain unchanged.
3.3 How GST is Calculated — The Land Value Deduction
Under-construction property sales are treated as a composite supply of goods and services. Since land is not subject to GST (Schedule III), the notifications provide a deemed deduction of 1/3 of total consideration towards land value.
GST Calculation Formula:
Taxable Value = Total Consideration − (1/3 × Total Consideration) = 2/3 of Total Consideration
GST Payable = Taxable Value × Applicable Rate (1% or 5%)
Practical shortcut: Effective GST as a percentage of the total flat value = 1% × 2/3 = 0.67% (affordable) or 5% × 2/3 = 3.33% (non-affordable)
Taxable Value = Total Consideration − (1/3 × Total Consideration) = 2/3 of Total Consideration
GST Payable = Taxable Value × Applicable Rate (1% or 5%)
Practical shortcut: Effective GST as a percentage of the total flat value = 1% × 2/3 = 0.67% (affordable) or 5% × 2/3 = 3.33% (non-affordable)
GST Calculation Examples for Homebuyers
| Property Type | Total Value | Deemed Land (1/3) | Taxable Value (2/3) | GST Rate | GST Payable | Total Cost |
|---|---|---|---|---|---|---|
| Affordable housing (Tier-2 city, 85 sqm, ₹38L) | ₹38,00,000 | ₹12,67,000 | ₹25,33,000 | 1% | ₹25,333 | ₹38,25,333 |
| Standard apartment (Mumbai, ₹70L) | ₹70,00,000 | ₹23,33,000 | ₹46,67,000 | 5% | ₹2,33,350 | ₹72,33,350 |
| Premium flat (₹1.5 crore) | ₹1,50,00,000 | ₹50,00,000 | ₹1,00,00,000 | 5% | ₹5,00,000 | ₹1,55,00,000 |
| Ready-to-move flat (OC received) | Any value | — | — | NIL | ₹0 | Base price only |
3.4 When Exactly Does GST Apply — The Completion Certificate Rule in Practice
The law is clear: GST applies to “supply of construction services” before completion. Once the builder obtains an OC/CC — even for a specific tower/phase — units in that completed phase are not subject to GST.
⚠️ Partial completion risk for buyers:
Large projects are developed in phases. If you buy in Phase 2 (under construction) while Phase 1 has already received OC — Phase 1 units are GST-free but your Phase 2 unit still attracts GST. Verify the OC status for the specific tower/building you’re purchasing in.
Builder delay risk: If a builder promises delivery but gets OC late — and you’ve been paying installments before OC (under-construction payments) — all those payments attracted GST. If OC comes before some payments were made, no GST on those remaining installments.

4. GST on Commercial Under-Construction Properties
Commercial under-construction properties (shops, offices, co-working spaces, warehouses, retail units) follow a different GST framework from residential properties:
| Commercial Property Type | GST Rate | ITC for Developer? |
|---|---|---|
| Under-construction commercial shop / office in a builder project | 12% with ITC (historical rate — verify post-Sept 2025 notification) | ✅ Yes (developer can claim ITC on inputs) |
| Under-construction commercial complex (standalone commercial) | 18% (works contract rate post-Sept 2025) | ✅ Yes (if not a composition scheme) |
| Ready-to-move commercial property (OC received) | NIL — not under construction | N/A |
| Renting of completed commercial property | 18% | ✅ Tenant can claim ITC |
🆕 Post-56th GST Council (22 Sept 2025) — Commercial Real Estate Rate Clarification:
The 56th Council eliminated the 12% GST slab for works contracts. Commercial real estate developer sales (construction services under NN 11/2017-CT(R)) need to be verified against the updated notification for applicable rate post-September 2025. The position as of May 2026 based on available information is that commercial under-construction sales are at the applicable works contract rate under NN 11/2017 — which may be 18% following the slab rationalization, though the specific commercial real estate notification carve-out must be verified. Builders with commercial projects must confirm the current applicable rate with their GST consultant before invoicing post-September 2025.

Builders with commercial projects must confirm the current applicable rate with their GST consultant before invoicing post-September 2025.
For commercial property buyers: Unlike residential buyers, businesses purchasing commercial office space or shops can claim ITC on the GST paid — provided the property is being purchased for use in their taxable business and they are GST-registered. This makes commercial under-construction property effectively less costly for B2B business buyers compared to residential buyers who cannot claim ITC.
5. Joint Development Agreements (JDA) — The Most Complex GST Area
A Joint Development Agreement is entered when a landowner gives land to a developer, and the developer constructs a project. The consideration can be:
- Revenue sharing: Developer pays the landowner a portion of sales revenue
- Area sharing: Developer gives the landowner a fixed number/percentage of constructed units
- Combination: Mix of cash + units
5.1 Landowner’s GST Position
The landowner gives Transfer of Development Rights (TDR) — the right to build on the land — to the developer. This is a supply of service by the landowner (not a sale of land, which would be exempt).
| Landowner Activity | GST Treatment |
|---|---|
| Granting TDR / development rights to developer | Supply of service — TAXABLE at 18% But: RCM applies — developer pays the GST, not the landowner NN 13/2017-CT(R) Entry 5C |
| Sale of land itself (not development rights) | NOT TAXABLE — Schedule III |
| Receiving constructed units from developer | Reverse of construction supply — no separate GST on receiving units |
| Selling those received units to end buyers (before OC) | TAXABLE — landowner becomes a “promoter” for those units; 1%/5% applies |
| Selling received units to buyers AFTER OC | NOT TAXABLE — ready-to-move property |
Tax planning for landowners: If a landowner’s share of units is sold only after obtaining OC — they pay no GST. This is often more tax-efficient than selling before OC. However, RERA requirements and market conditions may not always allow this timing flexibility.
5.2 Developer’s GST Position in JDA
The developer has three separate GST obligations in a JDA:
- Pay RCM on TDR received from landowner (18% on TDR value — see below)
- Charge GST on units sold to end buyers (1%/5% on under-construction units)
- Charge GST on units “sold” to landowner — the units given to the landowner as consideration represent a supply by the developer
5.3 Transfer of Development Rights (TDR) — RCM on Developer NN 13/2017-CT(R) Entry 5C
TDR Under RCM — How It Works:
When a landowner provides TDR (development rights) to a developer:
→ The landowner does NOT collect or pay GST
→ The developer pays 18% GST under RCM on the value of TDR
→ Value of TDR = Proportionate value based on area sold to independent buyers for similar units in the same project
Time of supply for TDR:
→ For the landowner (as supplier): Earliest of (a) date of possession of units to landowner, OR (b) date of completion certificate for those units
→ For the developer (paying RCM): The tax must be paid at time of supply

Time of supply for TDR:

→ For the developer (paying RCM): The tax must be paid at time of supply
5.4 Valuation and Time of Supply for TDR — CBIC Circular 55/29/2018
Valuing TDR is complex since there is no monetary payment from developer to landowner (in area-sharing JDA). CBIC Circular 55/29/2018-GST established the methodology:
- TDR value = Market value of similar area at the time of TDR transfer
- Derived from the price at which the developer sells comparable units to independent buyers in the same project
- Proportionate calculation based on the area of land transferred relative to total project area
⚠️ The TDR ITC paradox:
The developer pays 18% RCM on TDR value. Can the developer claim this as ITC?
The developer pays 18% RCM on TDR value. Can the developer claim this as ITC?
- If the project is a residential project under the 1%/5% no-ITC scheme → ITC on TDR RCM is also blocked
- If the project is commercial → ITC on TDR RCM may be available
6. Works Contract in Real Estate — GST for Contractors NN 11/2017-CT(R)
Civil contractors, structural engineers, MEP (mechanical, electrical, plumbing) contractors — all who provide works contract services for construction — charge GST on their services.
Current Rate Structure for Works Contracts (Post 22 September 2025)
| Works Contract Category | Rate (Pre-Sept 2025) | Rate (Post-22 Sept 2025) |
|---|---|---|
| General works contract (commercial/industrial construction) | 18% | 18% — no change |
| Works contract for government infrastructure (earlier at 12%) | 12% | 18% — 12% slab eliminated |
| Works contract for affordable housing by developer | 12% | 18% — 12% slab eliminated |
| Pure labour contract for government housing (EWS/LIG) | Exempt | Exempt — unchanged |
| Works contract for original construction by government/local authority for their own use | 12% | 18% |
| Sub-contractor’s work on any project | 18% always | 18% — unchanged |
⚠️ Major impact on affordable housing developers (post-Sept 2025):
A developer building affordable housing (selling to buyers at 1% GST, no ITC) was previously paying 12% GST on works contract from their civil contractor. From 22 September 2025, the contractor charges 18%. The developer: (a) cannot claim ITC on this under the 1%/5% scheme, (b) pays 6% more in contractor GST cost. For a ₹50 crore construction project, this is an additional ₹3 crore GST cost — absorbed entirely by the developer or passed on through higher flat prices.
The 56th Council partially offset this by reducing cement GST from 28% to 18% — a key construction input cost saving.

What Qualifies as “Works Contract” in Construction?
Works contract = contract involving both goods (materials) and services (labour/skill) resulting in construction/installation/fabrication of immovable property. Any contract where:
- Civil construction (RCC, brickwork, plastering, tiling)
- Electrical wiring and fittings (if site-specific installation)
- Plumbing, sanitation, HVAC installation
- Steel fabrication and erection at site
- Painting, polishing (if part of a construction contract)
7. RCM in Construction — The 80% Registered Supplier Rule § 9(4) CGST, NN 07/2019-CT(R)
Real estate developers/promoters must procure at least 80% of their total inputs and input services from registered GST suppliers. If they fall below this threshold, they must pay GST under RCM on the shortfall.
The 80% Rule — Explained:
If total procurement value for the project = ₹10 crore
Minimum from registered suppliers = 80% = ₹8 crore
If actual procurement from registered = ₹7 crore
Shortfall = ₹1 crore
RCM payable = 18% on ₹1 crore = ₹18 lakh (paid in cash, no ITC available to developer under the 1%/5% scheme)
If total procurement value for the project = ₹10 crore
Minimum from registered suppliers = 80% = ₹8 crore
If actual procurement from registered = ₹7 crore
Shortfall = ₹1 crore
RCM payable = 18% on ₹1 crore = ₹18 lakh (paid in cash, no ITC available to developer under the 1%/5% scheme)
Key Exclusions from the 80% Calculation
- Cement purchases — excluded from the 80% calculation (irrespective of supplier registration)
- Capital goods — generally excluded
- Services from government entities (covered under § 9(3) separately)
⚠️ Practical implications:
Developers must maintain detailed procurement registers tracking the registered vs unregistered supplier ratio on each project. Many small contractors (electricians, plumbers, painters) in the construction supply chain are unregistered. Exceeding the 20% unregistered procurement threshold silently creates an RCM liability that developers discover only at year-end reconciliation.

8. ITC in Real Estate — What Builders Can and Cannot Claim
| Developer Type | ITC Status | Notes |
|---|---|---|
| Residential developer under 1% or 5% scheme (no-ITC scheme) | ❌ No ITC on any inputs | All GST on materials, contractor services, RCM, TDR RCM — pure cost |
| Commercial developer (18% GST on sales, ITC scheme) | ✅ ITC available on inputs | Subject to § 17(5)(c)/(d) blockage — civil structure construction ITC still blocked (post Finance Act 2025) |
| Mixed project (residential + commercial) | Pro-rated | ITC available proportionate to commercial area; none for residential. Complex calculation per Rule 42. |
| ITC on TDR RCM (18%) for residential developer | ❌ Blocked | No ITC scheme → TDR RCM is a cost |
| ITC on works contract services for own construction | ❌ Blocked per § 17(5)(c) | Even for commercial developers — works contract for own building is blocked unless sub-contracted further |
🆕 Safari Retreats Impact on Real Estate Developers (Finance Act 2025 Retrospective Amendment):
Before October 2024, there was hope that commercial real estate developers building properties for renting (malls, office parks) could claim ITC on construction costs citing the Safari Retreats judgment. After the Finance Act 2025 retrospectively changed “plant or machinery” to “plant and machinery” in § 17(5)(d), this avenue is closed — retroactively from 1 July 2017. Mall developers, commercial real estate firms, and hospitality companies that had claimed ITC based on the Safari Retreats interpretation should review their position and make necessary reversals if applicable.

9. Affordable Housing — PMAY, EWS/LIG & GST Exemptions
PMAY (Pradhan Mantri Awas Yojana) — GST Treatment
| PMAY Activity | GST Rate |
|---|---|
| Pure labour contracts for construction of single residential units under PMAY (EWS/LIG) — by any person | EXEMPT NN 12/2017, Entry 10 |
| Works contract (goods + services) for PMAY housing construction | 18% (post-Sept 2025) — not exempt if involves goods |
| Developer selling PMAY-qualifying flat to buyer | 1% (if criteria met) or Exempt for EWS/LIG if fully government-sponsored |
| Beneficiary-Led Construction (BLC) — individual builds own house under PMAY | Materials at applicable rates; pure labour services exempt |
PMAY-U (Urban) vs PMAY-G (Rural): Urban housing under PMAY-U has more structured GST treatment. Rural housing under PMAY-G often involves direct government grants with pure labour contracts that are exempt. The key test is always: is it a pure labour contract (exempt) or a works contract with significant material supply (taxable at 18% post-rationalization)?
10. Redevelopment Projects and Society Reconstruction
Redevelopment (where an existing housing society gives land to a developer for construction of new, larger buildings) has unique GST treatment:
| Transaction | GST Treatment |
|---|---|
| Society grants development rights to developer | Supply of TDR by society → Developer pays 18% RCM |
| Developer constructs new units and gives existing members like-for-like units | Deemed supply by developer — 1%/5% as applicable on value of those units |
| Developer sells additional units (beyond society members’ share) to new buyers | Normal 1%/5% GST applies |
| Corpus fund paid by developer to society/members for displacement | Part of development cost — no separate GST on corpus fund payment |
| Rental compensation paid to displaced members during construction | Not a supply — compensation payment; no GST |
Redevelopment — GST Flow Example
Sitaram Co-op Housing Society (Mumbai, 50 members) gives their plot to Horizon Developers. Developer builds 50 new flats for existing members + 30 additional flats for sale.
- Society grants TDR → Developer pays RCM: 18% on value of TDR (based on proportionate market value)
- Developer provides 50 flats to members: Deemed supply by developer → GST at 5% on value of those 50 flats (if non-affordable; 1% if affordable). Time of supply = possession or OC, whichever earlier
- Developer sells 30 additional flats: Normal 5%/1% GST charged to new buyers
- Members selling their received flats (before OC): Members become promoters for those units — 5% or 1% GST applies
- Members selling after OC: No GST — ready-to-move
11. GST on Long-Term Lease of Land and Land Sale
| Transaction | GST? | Rate |
|---|---|---|
| Outright sale of land | No | Schedule III Entry 5 — not a supply |
| Long-term lease of land (≥30 years) to developer for construction | Yes — RCM | 18% — developer pays RCM under NN 13/2017 Entry 5B |
| Short-term lease of land (tenancy/licence) | Yes | 18% — forward charge if supplier is registered |
| Long-term lease of industrial plot (e.g., MIDC, GIDC, SIDCO) | Yes — RCM | 18% — RCM on developer/industrial unit |
| Assignment of right to use land by government to developer | Yes — RCM | 18% — government service to business entity under RCM |
Post-Agratas AAR (Nov 2025): Even the ITC on GST paid for a long-term land lease (where the purpose is construction) may be blocked under § 17(5)(d) — if the land lease is tied to construction of an immovable property. The Agratas Energy AAR held that such lease ITC cannot be claimed. Developers and industrial companies entering long-term land leases for factory/building construction should note this position.
12. GST on Ancillary Property Charges
| Charge | GST? | Rate | Notes |
|---|---|---|---|
| Parking space (covered / open) | Yes | 18% (if sold separately) / part of flat price (if combined) | If bundled with flat as single price → 5%/1%. If separate invoice → 18% |
| Club house membership / amenity charges | Yes | 18% | Taxable service; ITC blocked for buyer under § 17(5)(b)(iii) |
| Preferential Location Charges (PLC) | Yes | 5%/1% if part of composite supply with flat; 18% if separate | Usually bundled — same rate as flat applies |
| Advance/booking amount | Yes | Same rate as the flat | Time of supply = date of advance payment |
| Maintenance charges (for maintenance period until society formation) | Yes | 18% | Maintenance = service; taxable at 18%; builder-managed |
| Society maintenance charges (after society formation) | Up to ₹7,500/month per member: Exempt; Above ₹7,500: 18% | — | Society is separate from builder; different GST threshold applies |
| GST on stamp duty / registration | No | N/A | Stamp duty and registration are state charges — not GST |
Buyer’s tip on composite pricing: When a builder includes parking + club membership + PLC in a single agreement price for the flat, the entire amount (after 1/3 land deduction) is taxed at 1%/5% along with the flat. If these are billed separately, each may attract 18%. Ask your builder whether these are composite supplies before signing — the tax difference can be significant for high-value amenities.
13. Impact of 56th GST Council Rate Rationalization on Construction
| Item / Service | Pre-22 Sept 2025 | Post-22 Sept 2025 | Net Impact on Construction |
|---|---|---|---|
| Cement (all types) | 28% | 18% | Major saving — 10% reduction on the biggest construction input |
| Steel (TMT bars, structural steel) | 18% | 18% | No change |
| Sand, aggregates, gravel | 5% (royalty-based) | 5% | No change |
| Tiles, marbles, granite | 18%/12% | 5% or 18% (rationalized) | Varies by type — some categories cheaper |
| Paints, varnishes | 18% | 18% | No change |
| Electrical fittings, wiring | 18%/12% | 18% or 5% | Some items cheaper (low-end fittings) |
| Works contract (civil) for builder to government | 12% | 18% | 6% cost increase for builders working on government projects |
| Works contract (civil) — commercial projects | 18% | 18% | No change |
The Cement Effect — A Hidden Price Reducer for Under-Construction Flat Buyers:
Cement’s GST reduction from 28% to 18% is effectively a 10-percentage-point reduction on a major construction input. For a typical residential building, cement accounts for 15-20% of construction cost. On a ₹50 crore project with ₹8 crore of cement:
Old cost: ₹8 crore + ₹2.24 crore (28% GST) = ₹10.24 crore (no ITC for residential developer)
New cost: ₹8 crore + ₹1.44 crore (18% GST) = ₹9.44 crore
Saving: ₹80 lakh per ₹50 crore project — a cost benefit that competitive builders should pass on to buyers.

14. Compliance for Real Estate Developers — Key Requirements
- GST Registration: Mandatory when aggregate turnover from real estate activity exceeds ₹40 lakh/₹20 lakh; registration at project commencement recommended
- Project-level tracking: Maintain separate procurement registers for each project to track the 80% registered supplier threshold
- GSTR-1 and GSTR-3B: Monthly/quarterly returns; all flat sales reported in GSTR-1
- Self-invoice for TDR RCM: Issue within 30 days of receiving TDR from landowner; pay RCM in cash
- Unsold inventory at project end: GST is payable on the deemed supply of unsold units at the time of OC issuance (if units are still under construction when OC is received)
- e-Invoicing: Applicable if developer’s aggregate turnover exceeds ₹5 crore — must generate IRN-stamped invoices for all flat sales and works contract receipts
- RERA compliance: Separate project account under RERA — GST collected must flow through the appropriate tax account
- ITC transition: Builders who started projects under the old scheme (12%/8% with ITC) and transitioned to the new scheme must reverse ITC per transition rules
15. Common Issues, Disputes & GST Notices in Real Estate
| Issue | Risk | Resolution |
|---|---|---|
| Not paying GST on advance booking amounts | GST demand from date of booking | Time of supply = advance payment date; GST must be paid on advances |
| Treating JDA unit transfer to landowner as non-taxable | Large demand for 1%/5% GST on developer’s deemed supply | Deem supply of construction to landowner at market value; charge GST at time of possession/OC |
| Not paying RCM on TDR in JDA | 18% demand + penalty on TDR value | Calculate TDR value based on proportionate market price; pay RCM on self-invoice within 30 days |
| Incorrectly classifying flat as affordable (to use 1%) | Demand for 4% difference (5% – 1%) on entire project | Verify carpet area AND value both meet criteria; both conditions are conjunctive (AND, not OR) |
| Not reversing ITC when switching from old (12% ITC) to new scheme (5% no ITC) | ITC reversal demand | File ITC-03 at time of scheme change; reverse proportionate ITC |
| Charging 18% GST on society maintenance (≤₹7,500/month) | Excess tax charged; refund claim by members | Maintenance ≤₹7,500/month/member is exempt; correct invoice issuance |
| Not paying GST on unsold units at time of OC | Demand for GST on deemed supply at OC | Calculate and pay GST on fair market value of unsold inventory at time of obtaining OC |
16. Case Studies
Case 1: Homebuyer — GST Calculation on a ₹80 Lakh Flat in Bengaluru
Property: 3-BHK under-construction flat in Bengaluru. Carpet area: 95 sqm. Total consideration: ₹80 lakh.
Affordable housing check: Metro city (Bengaluru) → limit is 60 sqm carpet area. Carpet area = 95 sqm → exceeds 60 sqm → NOT affordable housing. Rate = 5%.
| Step | Calculation | Amount |
|---|---|---|
| Total flat value | — | ₹80,00,000 |
| Deemed land deduction (1/3) | ₹80L × 1/3 | ₹26,67,000 |
| Taxable value (2/3) | ₹80L − ₹26.67L | ₹53,33,000 |
| GST @ 5% | 5% × ₹53.33L | ₹2,66,650 |
| Total payable to builder (excluding stamp duty) | ₹80L + ₹2.67L | ₹82,66,650 |
If the same flat had been in a non-metro city (e.g., Nagpur) with carpet area ≤90 sqm at ₹40L value — it would qualify as affordable housing at 1%.
Case 2: Developer — JDA with Landowner (Area Sharing Model)
Landowner gives 1-acre plot in Pune to Skyline Developers. Agreement: developer builds 100 flats, gives 20 to landowner, sells 80.
| Transaction | GST |
|---|---|
| Landowner gives TDR to developer | Developer pays 18% RCM on TDR value If market value = ₹5 crore → RCM = ₹90L (cannot be claimed as ITC in residential scheme) |
| Developer builds and gives 20 flats to landowner (deemed supply) | 5% on 2/3 of market value of those 20 flats If 20 flats worth ₹2 crore each = ₹40 crore GST = 5% × ₹26.67 crore = ₹1.33 crore |
| Developer sells 80 flats to public at ₹2 crore each | 5% × ₹1.33 crore per flat = ₹6.67L per flat Total: 80 × ₹6.67L = ₹5.33 crore |
Case 3: Contractor — Rate Change Impact (Post Sept 2025)
BuildRight Construction was awarded a ₹20 crore civil works contract for an affordable housing project in October 2025.
| Period | Rate | Tax on ₹20 crore |
|---|---|---|
| Before 22 Sept 2025 (old rate) | 12% | ₹2.40 crore |
| After 22 Sept 2025 (new rate) | 18% | ₹3.60 crore |
| Additional GST burden on developer | ₹1.20 crore extra — which developer cannot claim as ITC (under 1%/5% scheme) | |
Developer must re-examine project viability or renegotiate flat prices. The cement GST reduction (28%→18%) partially offsets this but typically not 1:1 since works contract labour forms a larger share.
17. Frequently Asked Questions
Q1. I’m buying a flat for ₹45 lakh with 85 sqm carpet area in Jaipur. What GST do I pay?
Jaipur is a non-metropolitan city. Affordable housing criteria for non-metro: carpet area ≤90 sqm AND value ≤₹45L. Your flat satisfies BOTH (85 sqm ≤90 sqm ✓ AND ₹45L ≤₹45L ✓). This qualifies as affordable housing. GST = 1% × (2/3 × ₹45L) = 1% × ₹30L = ₹30,000. Total payment: ₹45,30,000 (excluding stamp duty).
Q2. The builder got OC for my tower last month. I still have 3 instalments to pay. Do I pay GST on them?
This is a critical question. GST applies to payments made before OC. Once OC is obtained, the property is legally “complete” — no GST on subsequent instalments. If your remaining instalments are due after the OC date, you should NOT pay GST on them. Request the builder not to include GST on post-OC invoices. Many builders continue charging GST on post-OC instalments (especially on possession-linked plans) — this is incorrect. You have the right to demand a revised invoice without GST after OC. Retain documentation of the OC date.
Q3. We are a housing society going for redevelopment. Will members have to pay GST when they get their new flats?
When the developer constructs and hands over new flats to existing members as part of redevelopment, it is a deemed supply by the developer — the developer pays the GST (1%/5%), not the individual members. Members receiving equivalent new flats for their surrendered old flats do not separately pay GST. However, if members then sell their new flats to buyers before OC, they become promoters for those units and must charge GST. After OC, members can sell without GST. The developer pays RCM on TDR received from the society.
Q4. My contractor quoted a works contract at 12% GST. He billed me in November 2025 for work done in October 2025. What rate applies?
The 12% GST slab for works contracts was eliminated effective 22 September 2025 (per the 56th GST Council rationalization notifications). Your contractor should have billed at 18% for work done from 22 September 2025 onwards. Invoices dated after 22 September 2025 at 12% may be technically incorrect — the contractor must charge the applicable rate at the time of supply (invoice date). Insist on corrected invoices at 18% and adjust the project budget accordingly. Work completed before 22 September 2025 but billed after remains a transitional question — time of supply rules (Section 14, CGST Act) apply based on invoice date.
Q5. As a small MSME contractor doing civil work for a residential developer, should I charge GST on my invoices?
If your aggregate annual turnover from civil works exceeds ₹20 lakh (₹10 lakh in special category states), you must register for GST and charge 18% on your works contract invoices. If below the threshold, you are unregistered — you don’t charge GST, but the developer’s 80% registered procurement calculation counts this payment as procurement from an unregistered supplier. If the developer’s unregistered procurement exceeds 20%, they pay 18% RCM on the shortfall — effectively creating an incentive for developers to prefer registered contractors. Voluntary registration and proper GST compliance makes you a more attractive vendor to large developers.
