For AY 2025-26, both the original return deadline (July 31, 2025) and the belated return deadline (December 31, 2025) have passed. The only option now is an Updated Return under Section 139(8A), filed using ITR-U.
Key facts:
- Window: closes March 31, 2027
- Additional tax now (we are in the 12-24 month window, April 2026 onwards): 50% on the additional tax and interest payable
- ITR-U can only be used to disclose additional or underreported income. It cannot be used to claim a refund or reduce your existing tax.
If your original AY 2025-26 return was filed on time but missed some income, a Revised Return is no longer possible (that window closed December 31, 2025). ITR-U is the only correction route.
For the ITR-2 form structure covering capital gains, house property, and salary income, this guide on [filing ITR for multiple income sources](https://taxgarden.in/blog/itr-filing-multiple-income-sources-salary-rental-fd-capital-gains-india) explains what goes in each schedule. The 50% additional tax computation for ITR-U is worth getting a CA to verify.
