Missed the ITR Deadline? Belated Returns and ITR-U Explained
The filing due date passing is not the end of the road, but every route after it costs something. Knowing which one applies to you — and what you give up — matters more than rushing to file the first form the portal offers.
Belated return
A return filed after the due date but within the belated window is a belated return. It is a valid return and it gets processed, but three things change:
- A late filing fee applies under section 234F.
- Interest under section 234A runs on unpaid tax from the due date.
- Certain losses cannot be carried forward — business loss and capital loss are lost for future set-off. House property loss survives; the others generally do not.
That last point is the expensive one. A trading loss you meant to carry forward for eight years disappears because a return went in three weeks late.
Revised return
If you have already filed and then spot an error — a missed interest income, a wrong bank account, a forgotten deduction — file a revised return under section 139(5). There is no fee for revising, and a belated return can itself be revised. Each revision replaces the last, so file the corrected version completely rather than filing "only the change".
Updated return (ITR-U)
Once the revised-return window closes, the updated return under section 139(8A) is what remains. It exists for one purpose: to let you declare income you did not declare earlier and pay the tax on it.
The constraints are real:
- It cannot be used to claim a refund, reduce your tax liability, or report a loss.
- It requires additional tax over and above the normal tax and interest — the rate rises the longer you wait.
- It cannot be filed for a year where search or survey proceedings are on foot.
Used properly, ITR-U closes an exposure before the department opens it. Used carelessly, it becomes an admission with no corresponding benefit.
Choosing between them
Work backwards from what you are trying to fix:
| Situation | Route | |---|---| | Not filed at all, still within the belated window | Belated return | | Filed, but something is wrong or missing | Revised return | | Belated and revised windows closed, undeclared income | ITR-U | | Want a refund you missed | Neither — a condonation request may be the only option |
Practical points
- Reconcile against AIS and Form 26AS before filing anything late. Most late filings are triggered by a mismatch the department has already seen.
- Pay the tax before you submit. Interest keeps accruing until payment, not until filing.
- If a notice has already arrived, respond to the notice — do not quietly file an ITR-U and hope the notice goes away.
- Where a refund is genuinely due and the window has closed, a condonation of delay application is the route, and it needs a reason better than oversight.
