What is GST Registration?
The Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based indirect tax levied on every value addition in India, introduced on 1st July 2017 under the Constitution (101st Amendment) Act, 2016. It replaced over 17 central and state indirect taxes including VAT, Service Tax, Excise Duty, and Octroi.
GST registration is the process of obtaining a 15-digit Goods and Services Tax Identification Number (GSTIN) from the GSTN (Goods and Services Tax Network) — the IT infrastructure backbone of GST — under the oversight of the Central Board of Indirect Taxes and Customs (CBIC).
Once registered, a business must collect GST from customers, file periodic returns, and deposit the tax with the government. In return, it can claim Input Tax Credit (ITC) on GST paid on purchases — ensuring that tax is only paid on the value added at each stage of the supply chain.

Benefits of GST Registration
- Input Tax Credit (ITC): Claim credit on GST paid on all business purchases — reduces your effective tax outgo significantly.
- Interstate Trade: Only GST-registered businesses can legally supply goods and services across state borders.
- Legal Business Identity: GSTIN provides a recognized legal identity for your business with banks, suppliers, and customers.
- E-Commerce Platform Access: Amazon, Flipkart, Swiggy and all major platforms require GST registration for seller onboarding.
- Bank Loans: GST returns are accepted as income proof for business loans by banks and NBFCs — builds credit history.
- Export Benefits: Exporters get zero-rated supply status (0% GST) and can claim refund of ITC on inputs used for exports.
- Government Tenders: Many government and PSU tenders require GST registration as a mandatory eligibility criterion.
- Composition Scheme: Small businesses can opt for a simplified scheme with fixed tax rates and quarterly filing — reducing compliance burden.
Regular GST Registration
Regular GST registration is the standard registration for all businesses above the threshold. Under regular registration, the business collects GST from customers, files monthly/quarterly returns, and claims Input Tax Credit on purchases. The government fee is zero — you only pay our professional fee for end-to-end assistance.
Free Registration: GST registration has zero government fee. The entire process is 100% online through the GST portal (gst.gov.in). Our professional fee covers end-to-end assistance — document preparation, ARN tracking, query resolution, and GSTIN delivery.

GST Registration — Step by Step Process

Late filing of GST returns (GSTR-1, GSTR-3B) beyond the due date

GST Composition Scheme — Simplified Tax for Small Businesses
The GST Composition Scheme is a simplified taxation scheme for small businesses with annual aggregate turnover up to ₹1.5 crore (₹75 lakh for special category states). Under this scheme, businesses pay GST at a fixed flat rate on their turnover instead of the standard GST rate, and file returns quarterly instead of monthly.
The Composition Scheme drastically reduces compliance burden — only 1 annual return (GSTR-9A) and 4 quarterly statements (CMP-08) are required instead of 13–25 monthly filings under regular GST. However, composition dealers cannot collect GST from customers, cannot claim ITC, and cannot make inter-state supplies.
Composition Scheme Tax Rates
| Business Category | GST Rate (Composition) | CGST | SGST |
|---|---|---|---|
| Manufacturers (excluding ice cream, pan masala, tobacco) | 1% of Turnover | 0.5% | 0.5% |
| Traders (goods dealers) — General | 1% of Turnover | 0.5% | 0.5% |
| Restaurants / Food Service (not serving alcohol) | 5% of Turnover | 2.5% | 2.5% |
| Service Providers (QRMP Composition) | 6% of Turnover | 3% | 3% |
| Mixed Suppliers (goods + services, services ≤10%) | 1% of Turnover | 0.5% | 0.5% |
Composition Scheme Restrictions: Composition dealers cannot issue tax invoices, cannot collect GST from customers, cannot claim Input Tax Credit (ITC), and cannot make inter-state supplies of goods. They must display "Composition Taxable Person — Not Eligible to Collect Tax on Supplies" on all invoices and business premises signboards.
Who Should Opt for Composition Scheme?
- Small Retailers & Kirana Stores: Local shops selling goods within the state with turnover below ₹1.5 crore — dramatically simplifies compliance.
- Small Manufacturers: Small production units supplying goods locally with simplified tax computation at 1% flat rate.
- Local Restaurants & Dhabas: Food service businesses selling locally at 5% flat rate without the complexity of monthly ITC reconciliation.
- Service Providers (QRMP): Small service providers eligible under the 6% composition rate with quarterly filing.
- B2C Businesses: Businesses primarily selling to end consumers (not B2B) — since ITC cannot be passed on, customers are not disadvantaged.
