Rejected an Invoice by Mistake in IMS — Can You Undo It Before Filing?
GSTZone Desk · Updated 2026
Short answer
Yes — as long as you haven’t yet filed GSTR-3B for that period, you can go back into IMS and change the action on that invoice from Rejected to Accepted (or Pending), and use the ‘Recompute 2B’ option to reflect the correction.
In detail
IMS actions aren’t locked the instant you click a button — they remain editable right up until the point your return for that period is actually filed. A mistaken rejection is fully recoverable within that window.
The practical fix is straightforward: go back into IMS, find the invoice, change its status from Rejected to Accepted (or Pending, if you need more time to verify it), and then use the portal’s ‘Recompute 2B’ facility so your GSTR-2B reflects the corrected status before you file.
Once GSTR-3B for that period IS filed, though, that window closes — you can’t retroactively edit an IMS action for an already-filed period. At that point, the fix shifts to normal reconciliation in a later period, potentially involving the supplier reissuing or clarifying the invoice.
GSTZone tip
Before filing any return, do one last pass through IMS specifically checking for any Rejected invoices — a rejection is the one IMS action with real consequences if it was a mistake, so it’s worth the extra thirty seconds of review before you commit to filing.
Related questions
Does the supplier get notified when I reject their invoice?+
Yes — a rejection in IMS reflects back to the supplier’s side, since it affects how that invoice is treated for their own liability workings, which is another reason to fix a mistaken rejection quickly.
What if I already filed the return with the wrong rejection in place?+
You’ll need to resolve it through normal follow-up with the supplier and reconciliation in a subsequent period — this is more involved than the simple pre-filing fix, so catching it before filing is always the better outcome.
