GST Registration: Who Needs It and When
Goods and Services Tax (GST) registration is one of the first compliance steps for many growing businesses. Knowing whether and when you need it helps you stay on the right side of the law and claim input tax credit correctly.
When registration is mandatory
Registration is generally required when:
- Your aggregate turnover crosses the prescribed threshold for your state and type of supply.
- You make inter-state taxable supplies.
- You sell through e-commerce operators.
- You are required to pay tax under reverse charge, or fall within other specified categories.
Some businesses also register voluntarily to claim input tax credit and to work more easily with GST-registered customers.
Documents you’ll typically need
- PAN of the business and its owners / partners / directors
- Aadhaar of the authorised signatory
- Proof of business constitution (partnership deed, incorporation certificate, etc.)
- Bank details (statement or cancelled cheque)
- Proof of principal place of business (electricity bill, rent agreement, NOC)
A printable checklist is available on our Resources page.
After you register
Once registered, you receive a GSTIN and must:
- issue GST-compliant invoices;
- file periodic returns (such as GSTR-1 and GSTR-3B); and
- reconcile your input tax credit against supplier filings each period.
Missing return deadlines attracts late fees and interest, so it helps to set up a filing calendar. You can see key recurring dates in our Knowledge Center.
