GST registration for service businesses: when you need it

If you sell only services, you generally need GST registration once your total turnover in a financial year crosses ₹20 lakh (₹10 lakh in some special category states). Tamil Nadu uses the ₹20 lakh limit.

What counts towards the limit

• All taxable services you bill, including to individuals
• Exempt services and exports also count towards the total
• Turnover across all your branches under the same PAN

When you must register even below the limit

• You supply services to customers in another state through certain platforms, or you make other inter-state supplies that the law covers
• You want to work with large companies that ask for a GSTIN on every invoice

Keep these ready

1. PAN and Aadhaar of the owner
2. Proof of business address (rent agreement or EB bill)
3. Bank account details
4. A photo of the shop or office board

Rules change. Confirm your case with a chartered accountant before you apply.
