The three-year limit on filing GST returns has been on the statute book since the Finance Act, 2023, notified with effect from 1 October 2023. For two years it sat there without effect, because the portal did not enforce it.
From the November 2025 tax period, it does.
GSTN's advisory of 29 October 2025 told taxpayers to file pending returns before the window closed. Many did not. The returns they did not file can no longer be filed at all.
Under the Finance Act, 2023 (notified by Notification No. 28/2023-CT dated 31.07.2023, w.e.f. 01.10.2023), a return under s.37 (outward supplies), s.39 (returns and payment), s.44 (annual return) or s.52 (TCS) cannot be furnished after three years from its due date. The restriction was implemented on the portal from the November 2025 tax period. Ten forms are covered — GSTR-1, 1A, 3B, 4, 5, 5A, 6, 7, 8, and 9/9C. There is no application, fee or condonation that reopens a barred period.
What is barred, and from when
The bar is not a single cut-off date. It rolls: each return becomes unfileable three years after its own due date.
| Return | Provision | Covers |
|---|---|---|
| GSTR-1, GSTR-1A | s.37 | outward supplies and amendments |
| GSTR-3B | s.39 | summary return and payment |
| GSTR-4 | s.39 | composition taxpayers, annual |
| GSTR-5 | s.39 | non-resident taxable persons |
| GSTR-5A | s.39 | OIDAR suppliers |
| GSTR-6 | s.39 | input service distributors |
| GSTR-7 | s.39 | TDS deductors |
| GSTR-8 | s.52 | TCS by e-commerce operators |
| GSTR-9 / 9C | s.44 | annual return and reconciliation statement |
So a GSTR-3B for October 2022, due 20 November 2022, became unfileable on 21 November 2025. A GSTR-9 for FY 2021-22, due 31 December 2022, became unfileable on 1 January 2026. Every month that passes closes another period, permanently.
What the bar actually costs
The liability does not disappear. Being unable to file a return is not being relieved of tax. The department can still assess the period — s.62 best judgment assessment for a non-filer, or a s.73 or s.74A demand. The taxpayer simply loses the ability to declare the correct figures on their own return.
ITC for the period is lost. Section 16(4) already caps credit at 30 November following the financial year. A period that cannot be returned at all removes any remaining route.
Recipients are affected. An unfiled GSTR-1 means the recipient's GSTR-2B never carried those invoices. Where the recipient claimed credit anyway, they now face a permanent mismatch that the supplier cannot cure by filing late.
Registration cannot be cleanly closed. Cancellation under s.29 requires the final return in GSTR-10, and pending returns block the process. A registration with barred periods is difficult to exit.
Refund claims fail. Rule 89 draws on filed returns. A refund for a period whose return was never filed has no basis to sit on.
What still works
GSTR-10, the final return, is under s.45, not s.39 — it is not in the enumerated list. It remains fileable.
DRC-03 voluntary payment is not a return. Where liability for a barred period is admitted, it can still be discharged through DRC-03, which stops interest running and demonstrates bona fides even though it does not substitute for the return.
Section 161 rectification and appellate remedies against any assessment order for the period remain available on their own terms.
Amendment through a later return. Section 39(9) permits correction of an omission or incorrect particular in a subsequent return, subject to the 30 November outer limit. Where that limit has not expired, an error in an older period can sometimes be corrected in a still-open one.
What to do now
Run a completeness check across every GSTIN. Not just the ones you actively file. Dormant registrations, TDS registrations taken for a single contract, ISD registrations, casual registrations — these are where unfiled periods hide.
Sort by due date, not by period. The bar attaches to the due date. An annual return has a much later due date than the months it covers, which means the annual return for an old year may still be open when the monthly returns for that year are shut.
File the oldest open period first. Late fee and interest are unavoidable; losing the ability to file is worse.
Reconcile before you lose the ability to correct. Once a period is barred, the reconciliation in GSTR-9C for that year cannot be fixed by amending the underlying return.
Document the barred periods. Where a period is already closed, record the position, the liability, and how it was discharged. That file will be requested.
