GST registration is mandatory once your turnover crosses the threshold (₹40 lakh for goods, ₹20 lakh for services in most states — lower in special category states), or the moment you sell across state lines or on an e-commerce marketplace, regardless of turnover. Here's the process, start to finish.
- 1
Gather your documents
PAN, Aadhaar, address proof for your place of business, a cancelled cheque or bank statement, and your business constitution proof (incorporation certificate, partnership deed, etc.).
- 2
Apply on the GST portal
Part A generates a Temporary Reference Number (TRN) after OTP verification; Part B is where you upload documents and details using that TRN.
- 3
Verification
A GST officer may raise a query or ask for clarification — most clean applications are approved without one, but respond within 7 working days if asked.
- 4
ARN and GSTIN
Once approved, you receive your GSTIN and registration certificate (Form GST REG-06), usually within 3–7 working days of a clean application.
The single biggest cause of delay
Address proof that doesn't clearly match the entity name — an electricity bill in a director's personal name, for instance, without a matching NOC. Always pair address proof with a signed NOC from the property owner when you don't own the premises.
After you're registered
Registration is the easy part — the recurring commitment is monthly or quarterly filing (GSTR-1 and GSTR-3B), and reconciling input tax credit against GSTR-2B every period. Missed filings attract late fees and interest even at zero tax liability, so set a recurring reminder from day one.
