Yes, you can claim missed ITC in a later month, but within limits.
Section 16(4) of the CGST Act sets the time limit: ITC on an invoice must be claimed by the earlier of:
- The due date of GSTR-3B for September of the financial year following the year of the invoice, OR
- The date of filing the annual return (GSTR-9) for that year
In practice, this means:
- Invoice dated in FY 2024-25: claim by September 2025 GSTR-3B due date (20 October 2025) or GSTR-9 filing, whichever is earlier
- Invoice dated in FY 2025-26: claim by September 2026 GSTR-3B (20 October 2026)
You can claim the missed ITC simply by entering it in Table 4A of the next GSTR-3B you file, as long as you are within the above window. No separate application is needed.
If the time window has already passed, the credit is permanently time-barred under Section 16(4). There is no appeal or restoration mechanism.
This [GSTR-3B ITC auto-population and Table 4 guide](https://taxgarden.in/blog/gstr-3b-itc-auto-population-phase-2-table-4a-locked-july-2026) explains how ITC flows through Table 4A and the time-limit framework.
