Every GST-registered business in Chennai must file periodic GST returns even in months with no sales. Missing a return blocks your next filing and attracts a daily late fee, so Chennai businesses need a reliable monthly compliance routine.
This guide explains which GST returns apply to a Chennai taxpayer, the due dates, and the QRMP option for smaller businesses.
What is GST Return Filing in Chennai?
A GST return is a statement of your outward supplies (sales), input tax credit and tax payable, filed online on the GST portal. There is no Chennai-specific return — the same central forms apply, tied to your GSTIN.
Regular taxpayers file GSTR-1 (sales) and GSTR-3B (summary and payment); composition dealers file CMP-08 and GSTR-4.
| GSTR-1 | Outward supplies — monthly (11th) or quarterly under QRMP |
|---|---|
| GSTR-3B | Summary return & tax payment — 20th monthly, or 22nd/24th under QRMP |
| CMP-08 | Composition dealers — quarterly by the 18th |
| Annual return | GSTR-9 by 31 December of the next financial year |

Frequently asked questions
Do I have to file GST returns in Chennai if there were no sales?
Yes. A nil GSTR-3B and GSTR-1 must still be filed; a nil return can be filed by SMS. Skipping it still attracts a late fee.
What is the QRMP scheme?
Quarterly Return Monthly Payment lets taxpayers with turnover up to ₹5 crore file GSTR-1 and GSTR-3B quarterly while paying tax monthly via a challan.
