Why “ITR last date 2026” is ambiguous
The phrase can mean three different things:
- the normal due date for a particular taxpayer;
- the belated-return deadline for AY 2026-27; or
- a date in calendar year 2026 for a return belonging to an older assessment year.
Always write the financial year, assessment year, taxpayer category and filing route before relying on a date.
FY 2025-26 means income from 1 April 2025 to 31 March 2026. Its return is normally filed in AY 2026-27.
Find your date in four steps
| ① Identify income year | ② Identify category | ③ Check whether already filed | ④ Apply the right final date |
|---|---|---|---|
| FY 2025-26 maps to AY 2026-27 | Salary, non-audit business, audit or transfer pricing | No return, valid return or invalid unverified return | Regular, belated or revised route |
If you are a salaried ITR-1 or ITR-2 filer
The usual normal date was 31 July 2026. If it passed, use section 139(4) by 31 December 2026, subject to earlier assessment completion. Pay applicable tax, fee and interest, then e-verify.
If you have non-audit business or professional income
Your AY 2026-27 normal date may be 31 August 2026. On 3 August 2026, this category is not yet late. File under section 139(1) instead of choosing a belated-return section merely because 31 July is visible in news reports.
If audit or transfer-pricing reporting applies
The normal dates are later. The audit report itself can have an earlier linked due date. These cases need careful professional handling and should not be reduced to a general salaried-person checklist.
What happens on 31 December 2026
Section 139(4) permits a belated return up to three months before the end of the relevant assessment year, or before completion of assessment, whichever is earlier. For AY 2026-27, that calendar date is 31 December 2026.
The portal being open on the date is not a promise that every case remains eligible. An assessment completed earlier can close the route. Do not treat the final date as a target date.
Revised return date is different
If you filed a valid original or belated return and later discover an omission or wrong statement, section 139(5) provides the revised route. For AY 2026-27, the revised-return period normally extends to 31 March 2027, or earlier assessment completion.
A fee under section 234-I applies when an AY 2026-27 revised return is furnished after 31 December 2026: ₹1,000 where total income does not exceed ₹5 lakh and ₹5,000 otherwise. This is different from section 234F for an original return filed late. Read the official section 234-I page.
What if 31 December is missed
Do not upload an ordinary belated return under the wrong year. Check whether an updated return under section 139(8A) is permitted. ITR-U can be available for up to 48 months after the end of the assessment year, but it has restrictions and additional tax.
An updated return normally cannot create or increase a refund, reduce tax or increase a loss. A limited condonation request under section 119(2)(b) may be relevant for certain genuine-hardship refund or loss claims, but approval is discretionary. CBDT Circular 11/2024 provides the current framework.
Do not assume that ITR-U is simply a late ITR with another name. Its conditions can make it unsuitable for a refund claim.
Illustration: two people on the same day
Illustration only: On 3 August 2026, Leena has salary income and should have filed ITR-1 by 31 July. She is late and can normally use section 139(4). Dev has eligible non-audit professional income and a 31 August normal date. He is still within time and should file a regular return. The calendar day is the same, but their routes differ.
Calendar reminders to set
- Your actual normal due date.
- A preparation date at least two weeks earlier.
- The 31 December belated date if already late.
- The 30-day e-verification deadline counted from submission.
- A check for section 143(1) intimation after processing.
- The revised-return deadline if a correction is likely.
An RTI request cannot extend any of these tax deadlines. Use the official portal, grievance, rectification, revision or appeal route that fits the problem.

Frequently asked questions
Is 31 July 2026 the last date for everyone?
No. AY 2026-27 has later normal dates for non-audit business, audit and transfer-pricing categories.
What is the belated ITR last date for a salaried person?
For AY 2026-27, it is normally 31 December 2026 or earlier assessment completion after the 31 July normal date is missed.
Can the assessment close the belated window early?
Yes. Section 139(4) uses the earlier of the calendar deadline and completion of assessment.
Can I revise after 31 December 2026?
For AY 2026-27, the revised-return window normally extends through 31 March 2027, but section 234-I can charge a fee after 31 December.
Does e-verification also have a 31 December deadline?
E-verification generally has a separate 30-day timeline from submission. Filing on the final day can therefore create special consequences if verification is delayed.
Should I wait until the last date if tax is payable?
No. File accurately as soon as possible. Time-based interest and practical risks can increase while you wait.
