Income tax return (ITR) filing via ITR-U

What Does Income Tax Return Filing via ITR‑U Mean? (Updated for 2026)
The concept of filing an updated income tax return was introduced through the Finance Act, 2022, to give taxpayers an extended opportunity to correct or declare additional income. Under this provision, taxpayers who missed filing their original or belated return or wish to rectify errors or omissions can file an updated return within 24 months from the end of the relevant Assessment Year (AY). To operationalise this mechanism, the CBDT notified Rule 12AC along with a dedicated form called ITR‑U. This form must be furnished whenever a taxpayer opts to file an updated return for any assessment year permitted under the law. Key Features of ITR‑U (As Applicable in 2026)
24‑Month Extended Time Window :
- Taxpayers are allowed to file an updated return Up to 24 months (2 years) from the end of the relevant AY. Like, for example, for AY 2024–25, an updated return can be filed up to 31 March 2027. This additional window helps individuals correct underreported income, missed disclosures, or other errors.
- Applicability of Section 139(8A) : Section 139(8A) permits filing an ITR‑U except in specific barred situations, such as Search or seizure cases, Survey operations, Cases involving prosecution, Returns with no additional tax outflow and Loss returns to reduce tax liability
ITR‑U May Be Filed Even If
- The taxpayer did not file the original or belated return. The taxpayer wishes to revise earlier disclosures and Additional income needs to be reported voluntarily
Updated Return for Earlier Years
- Since the provision came into effect on 1 April 2022, taxpayers were initially allowed to update returns for AY 2020–21 and AY 2021–22. This has continued year after year, making ITR‑U available for multiple past assessment years on a rolling basis.
Updated Returns for Earlier Financial Years
- ITR‑U also allowed updated filing for FY 2019–20 (AY 2020–21) and FY 2020–21 (AY 2021–22). Taxpayers could correct omissions or income mismatches through the updated return mechanism for these years as well.
Why ITR‑U Matters in 2026:
- As compliance systems evolve (AIS, TIS, GST data matching, SFT reporting), discrepancies are more easily flagged. ITR‑U serves as a voluntary compliance channel, helping taxpayers Avoid future litigation, Correct mistakes proactively, Regularise income reporting and Reduce penalties by timely disclosure
