GST Services — Complete GST Compliance by a GCA
GST is India's single largest indirect tax — and its compliance obligations touch every business, every month. GCA provides end-to-end GST services: from first-time registration to annual return, reconciliation, export refunds, e-invoicing, and officer notices.
Goods & Services Tax — India's Biggest Tax Reform
Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based tax levied on the supply of goods and services across India. Introduced on 1 July 2017, it is the largest indirect tax reform in Indian history — replacing a fragmented system of over 17 central and state taxes with a single, unified framework administered through the GST Common Portal.
GST follows the principle of "One Nation, One Tax, One Market" — eliminating the cascading effect of tax on tax that previously increased costs for businesses and consumers alike. It operates on a dual structure: Central GST (CGST) and State GST (SGST) for intra-state supplies, and Integrated GST (IGST) for inter-state supplies and imports.
The GST Council — comprising the Union Finance Minister and State Finance Ministers — governs rates, exemptions, and policy amendments. The law is dynamic, and businesses need professional support to keep pace with frequent notifications, circulars, and changes in return formats.
Taxes Merged into GST
These taxes continue to be levied separately by Centre/State governments and are not available as Input Tax Credit under GST.

GST Compliance for Different Business Types
GST obligations differ based on business type, turnover, and nature of supply. GCA has experience across sectors — from local traders to exporters and e-commerce sellers.
👤 Small Business / Proprietors & Traders +
For small businesses with turnover below ₹1.5 crore (goods) or ₹50 lakh (services), the Composition Scheme is often the best option — simple quarterly filing at a flat tax rate, lower compliance burden.
For regular scheme businesses, GCA handles monthly GSTR-1 and GSTR-3B filings, GSTR-2B reconciliation with purchase register, and the annual GSTR-9 return.
🏛 Companies & LLPs (Turnover above ₹5 Crore) +
Larger entities face mandatory e-invoicing (IRN/QR code generation for every B2B invoice), monthly GSTR-1 and GSTR-3B, GSTR-2B reconciliation at scale, and mandatory GSTR-9C (self-certified reconciliation statement).
GCA assists with ERP integration for e-invoicing, managing large-volume reconciliations, and GSTR-9/9C annual compliance.
🛍 E-Commerce Sellers (Amazon, Flipkart, Meesho, etc.) +
Sellers on e-commerce platforms have a unique compliance profile. GST is mandatory regardless of turnover for most e-commerce sellers. The platform (operator) deducts TCS (Tax Collected at Source) at 1% on net value of taxable supplies — which appears in GSTR-8 filed by the operator and can be claimed by sellers in GSTR-3B.
Multi-state selling through e-commerce requires separate GST registration in each state where the operator's warehouses are used for storage and dispatch of your goods.
🌎 Exporters of Goods & Services +
Exports are treated as zero-rated supplies under GST — meaning GST is not charged on exports. Exporters can either:
- File a Letter of Undertaking (LUT) and export without payment of GST — then claim refund of accumulated ITC, or
- Export on payment of IGST and claim refund of the IGST paid
GCA handles annual LUT filing, GST refund applications (RFD-01), and SEZ supply compliance for all categories of exporters.

Frequently Asked Questions — GST
What is the GST threshold for a service provider in India? +
A service provider with aggregate turnover exceeding ₹20 lakh per year must register under GST (₹10 lakh for special category states including the North-Eastern states and Uttarakhand). Aggregate turnover is calculated across all states on the same PAN. Voluntary registration is also available and often beneficial for B2B businesses below the threshold.
What is the difference between GSTR-1 and GSTR-3B? +
GSTR-1 is the statement of outward supplies — every invoice issued to customers is reported here. It is used by recipients to claim ITC and populates their GSTR-2B automatically. GSTR-3B is the monthly summary return where you declare your total output tax liability, ITC claims, and make the net tax payment to the government. Both must be filed each month (or quarterly under QRMP). GSTR-3B data must be reconciled with GSTR-1 and GSTR-2B.
Who is required to generate an E-Invoice under GST? +
E-invoicing (generation of Invoice Reference Number / IRN and QR code) is currently mandatory for B2B transactions by businesses whose aggregate annual turnover in any preceding financial year (from 2017-18 onwards) exceeds ₹5 crore. The system requires each invoice to be reported to the Invoice Registration Portal (IRP) and authenticated with a unique IRN before it is issued to the buyer. Failure to generate an IRN makes the invoice invalid for ITC purposes in the buyer's hands.
What is the QRMP scheme and who should opt for it? +
The Quarterly Return Monthly Payment (QRMP) scheme is available to GST-registered taxpayers with annual aggregate turnover up to ₹5 crore. Under this scheme, GSTR-1 and GSTR-3B are filed quarterly, but tax is paid monthly (in months 1 and 2 of the quarter) through Form PMT-06, based on a fixed sum or self-assessed amount. Businesses with simpler monthly transactions benefit the most — reduced compliance burden without losing timely payment discipline.
Can Input Tax Credit (ITC) be claimed on all business purchases? +
No. ITC is available only on purchases used for business purposes and taxable supplies. It is blocked on certain specified items under Section 17(5) of the CGST Act, including: motor vehicles (with exceptions), food & beverages, club memberships, health & beauty services, works contract for immovable property, and goods used for personal consumption. Additionally, ITC can only be claimed if the supplier has reported the invoice in GSTR-1 and it appears in your GSTR-2B — making monthly reconciliation critical.
What happens if a GST return is not filed for several months? +
Filing late or not filing GST returns has multiple consequences: (1) Late fee accumulates at ₹50 per day per return (₹20/day for nil returns), (2) Interest at 18% p.a. accrues on unpaid tax, (3) E-Way Bill generation is blocked if GSTR-3B is not filed for two consecutive tax periods, (4) The GST department may cancel your registration suo motu for prolonged non-filing, and (5) Your customers cannot claim ITC on invoices from you if your returns are not filed. GCA manages all return filings proactively to ensure none of these situations arise.
