Belated return last date
The Central Board of Direct Taxes (CBDT) has announced category-wise due dates for FY 2025-26 — a change from the older one-size-fits-all approach. Budget 2026 introduced a new tiered deadline structure that gives additional time to non-audit businesses and professionals.
Budget 2026 Change
Due date for ITR-3 and ITR-4 (non-audit cases) has been extended to 31 August 2026, effective from FY 2025-26. This benefits freelancers, professionals, and small business owners.
| Taxpayer Category | ITR Form | Due Date | Status |
|---|---|---|---|
Salaried individuals, pensioners, HUF (no audit) | ITR-1, ITR-2 | 31 July 2026 | Primary |
Non-audit business owners, freelancers, professionals | ITR-3, ITR-4 | 31 August 2026 | Extended |
Tax audit cases (companies, large businesses, professionals above threshold) | ITR-3, ITR-5, ITR-6, ITR-7 | 31 October 2026 | Audit |
International / specified domestic transactions (Transfer Pricing — Form 3CEB) | All applicable | 30 November 2026 |
TP Cases |
Belated return (missed original deadline) | All forms | 31 December 2026 | Late |

⚠ Tax Audit Report Due Date
If your ITR due date is 31 October 2026, the tax audit report (Form 3CA/3CB/3CD) must be filed one month earlier — by
30 September 2026.For transfer pricing cases (ITR due 30 November), audit report is due by 31 October 2026.
Many taxpayers confuse Financial Year (FY) and Assessment Year (AY). Here’s the simple distinction:
When you log into the Income Tax E-Filing portal (incometax.gov.in) to file your return for income earned in FY 2025-26, you will select AY 2026-27 from the dropdown.
✓ Important Note for AY 2026-27
Returns for AY 2026-27 are still governed by the Income Tax Act, 1961(old Act), even though the new Income Tax Act, 2025 came into force on 1 April 2026. The new Act will apply from Tax Year 2026-27 (i.e., income earned after 1 April 2026).
Missing the ITR filing last date for FY 2025-26 is not the end of the road, but it comes with real financial consequences. Here’s a complete breakdown:
| Section | Trigger | Rate |
|---|---|---|
234A | Tax unpaid after due date | 1% per month (or part) from due date until filing |
234B | Advance tax paid is less than 90% of assessed liability | 1% per month from 1 April until ITR processing date |
234C | Short payment of advance tax instalments | 1% per quarter on the shortfall |
Interest under these sections is auto-calculated by the e-filing portal when you submit your return. There is no separate step required.
Missing the ITR filing last date for FY 2025-26 does not mean you cannot file at all. The Income Tax Act provides several remedies — each with its own cost and limitations.
You can file a belated return up to 31 December 2026. A late fee of ₹1,000 to ₹5,000 applies depending on your income. However, you cannot carry forward most losses (capital losses, business losses) if you file a belated return.
If you already filed on time but spotted an error, file a revised return before 31 March 2027. This is now extended from the earlier December deadline, giving you more time to fix mistakes like wrong bank details, missed deductions, or incorrect income figures.
If both the above deadlines are missed, you can still voluntarily file an updated return within 4 years (by 31 March 2031). However:
✕ Important: Loss Carry-Forward is Lost on Belated Filing
If you miss the original due date, you permanently lose the right to carry forward capital losses, business losses, and speculation losses to future years. This can significantly increase your tax burden going forward.
The financial penalties are just one side of the story. Late or non-filing has wider implications:
✓ Documents to keep ready before filing
Form 16 (from employer), Form 16A (TDS on other income), bank statements, investment proof (for 80C, 80D, NPS), capital gains statement from broker, home loan certificate, and Annual Information Statement (AIS) from the e-filing portal.
The last date is 31 July 2026 for salaried individuals and non-audit taxpayers filing ITR-1 or ITR-2. For ITR-3 and ITR-4 (non-audit business/professional cases), the deadline is 31 August 2026. Audit cases have until 31 October 2026.
Yes. You can file a belated return up to 31 December 2026 with a late fee of ₹1,000 (income ≤ ₹5 lakh) or ₹5,000 (income > ₹5 lakh). However, you will lose the right to carry forward most losses, and interest under Section 234A will also apply on any unpaid tax.
Yes. Budget 2026 extended the revised return deadline from 31 December to 31 March of the following year. For AY 2026-27, the revised return can be filed up to 31 March 2027.
Under Section 234F (or Section 428 of the new Income Tax Act for future years), a late filing fee of ₹5,000 applies if income exceeds ₹5 lakh, and ₹1,000 if income is ₹5 lakh or below. This is in addition to interest under Sections 234A, 234B, and 234C on any unpaid tax.
No. The new Income Tax Act, 2025 came into force on 1 April 2026 but applies only from Tax Year 2026-27 onwards (income earned from 1 April 2026). All returns for FY 2025-26 (AY 2026-27) are still governed by the Income Tax Act, 1961, using the existing ITR forms on the e-filing portal.
You can file an updated return (ITR-U) within 4 years from the end of the assessment year, i.e., up to 31 March 2031. However, an additional tax of 25% to 50% on aggregate tax and interest will apply, and you cannot use ITR-U to claim refunds or reduce income.
Yes. Returns filed after the due date are typically processed later than on-time filings, and refunds can take 20 to 45 days or even up to 6 months to be credited to your bank account.
Don’t wait for deadline, file your ITR now quickly and avoid penalties easily.
