A plain-English guide to GST registration thresholds, documents, and the step-by-step application process.
Goods & Services Tax (GST) registration is mandatory once your turnover crosses the prescribed threshold, and for certain businesses regardless of turnover. This guide breaks down who needs it and how to get registered.
Who must register
- Businesses with turnover above ₹40 lakh (goods) or ₹20 lakh (services) in most states.
- Anyone making inter-state supplies.
- E-commerce sellers and operators.
- Casual taxable persons and non-resident taxable persons.
Documents you will need
- PAN of the business or proprietor.
- Aadhaar of the authorised signatory.
- Proof of business address (utility bill or rent agreement with NOC).
- Bank account details (cancelled cheque or statement).
The process
Submit the REG-01 application, respond to any REG-03 clarification, and receive your GSTIN and certificate — typically within 3 to 5 working days. A CA review before submission avoids the most common rejections.
