TDS credit carry forward works differently from loss carry forward, and the rules are worth understanding precisely.
When TDS is more than your tax liability for a year, the excess becomes a refund claim, not a carry forward item. You claim it in your ITR by declaring the TDS in the TDS credit schedule (Schedule TDS1 or TDS2). If tax payable is nil, the entire TDS becomes a refund.
What if you missed claiming TDS in a prior year?
TDS does not have a standalone carry forward mechanism. But you have two options:
Option 1: Revise the return (if not yet assessed)
If the original return was filed and the time window for revision under Section 139(5) is still open (within one year of filing or before assessment, whichever is earlier), file a revised return to include the missed TDS credit.
Option 2: Updated return under Section 139(8A)
For AY 2022-23 onwards, you can file an updated return (ITR-U) within 48 months of the end of the relevant assessment year. ITR-U for AY 2022-23 can be filed until 31 March 2027. Note: ITR-U cannot reduce your tax liability below the originally filed amount, so it works best when you previously filed NIL return and the TDS was not declared at all.
Practical steps:
1. Pull Form 26AS and AIS for all years where TDS was deducted
2. Cross-check against the TDS schedule in your filed ITR
3. If TDS was missed, file ITR-U for the relevant AY with the correct TDS credit
