How to use this calculator
- Enter the aggregate turnover for the year and the number of states registered.
- Choose the financial year to match your situation.
- Read which annual return is needed and the turnover thresholds in the result.
Thresholds and optional filing depend on the year; check the notification for that year.
The result is an estimate for the figures you enter. It is not a filed return, a certificate or professional advice. Rates, thresholds and section numbers change with each Finance Act, and the Income-tax Act, 2025 applies from 1 April 2026 with new section and form numbers.
