Received Form GSTR-3A – the notice under Section 46 for not filing your GST return (GSTR-3B, GSTR-4 or GSTR-10)? It is the simplest notice in the system with the simplest cure: file the pending return within 15 days with late fee and interest, and the matter closes automatically – no reply is needed or even possible. Ignore it, and the officer can assess you on best judgment under Section 62, using your GSTR-1, e-way bills and other available data. This guide covers the deadlines, the escape routes and what to do when the notice itself is wrong.
Deadline helper
How the process runs
| Stage | What happens | Your window |
|---|---|---|
| GSTR-3A notice (s.46) | System-generated notice for the unfiled return – no demand yet | File the return within 15 days |
| Best-judgment assessment (s.62) | Officer assesses on available data (GSTR-1, e-way bills, other records) – order in ASMT-13 with summary in DRC-07; can issue within 5 years of the annual-return due date | Avoid it by filing within the 15 days |
| ASMT-13 withdrawal | File the valid return within 60 days of the order – it stands deemed withdrawn; a further 60 days is available on payment of additional late fee of Rs 100 per day (CGST; matching SGST applies). Interest u/s 50 and late fee u/s 47 remain payable either way | 60 days + 60 days |
| If still ignored | The ASMT-13 demand becomes recoverable; registration can be cancelled u/s 29(2)(c) for continued non-filing | – |
What non-filing also triggers (beyond the notice)
- GSTR-1 gets blocked – Rule 59(6): you cannot file GSTR-1/IFF if the previous month’s GSTR-3B is pending.
- E-way bills get blocked – Rule 138E: after two consecutive tax periods of default, e-way bill generation is barred – business movement stops.
- Registration cancellation – Section 29(2)(c): continued non-filing (six months for monthly filers, two tax periods for QRMP) invites a REG-17 cancellation notice – see our REG-17 reply tool.
When the GSTR-3A itself is wrong
Notices are system-fired and sometimes wrong. Common cases and the response route (since there is no reply tab):
- Return actually filed – check the ARN; if filed before the notice, raise a grievance on the GST Self-Service Portal (selfservice.gstsystem.in) attaching the acknowledgment, and keep a copy for the record.
- Registration already cancelled effective before the period – no return was due. GSTN itself acknowledged (advisory of July 2025) a glitch that sent GSTR-3A notices for GSTR-4 to composition taxpayers whose registrations were cancelled earlier – such notices can be disregarded per the advisory; for other cases, raise a grievance with the cancellation order attached and inform the jurisdictional officer in writing.
- Not liable to file the return type mentioned (for example scheme switched) – grievance with proof of the correct registration status.
Frequently asked questions
Is there a penalty in the GSTR-3A itself?
No – the notice carries no demand. Filing within 15 days costs only the normal late fee under Section 47 (with its caps) and interest under Section 50 on any tax paid late. The expensive outcomes start only if you let it reach Section 62.
The officer has passed an ASMT-13 with a huge estimated demand. Is it final?
Not if you act within 60 days (extendable by a further 60 with additional late fee) – file the actual return and the assessment order is deemed withdrawn automatically. The estimate vanishes; only your real liability with interest and late fee remains. Beyond 120 days, the remedy is an appeal under Section 107.
I received GSTR-3A for a period after my registration was cancelled. What do I do?
If cancellation was effective before the period, no return was due – raise a grievance on the self-service portal with the cancellation order, and keep the written record. A GSTN advisory has acknowledged wrongly-fired notices of this kind.
Which returns can trigger GSTR-3A?
The regular returns – GSTR-3B (monthly/quarterly), GSTR-4 (composition annual), and GSTR-10 (final return after cancellation). The cure in every case is filing the pending return.
