The clock is ticking. Every year, millions of Indians miss the ITR deadline and pay thousands in penalties and interest. Here is everything you need to know — the exact dates, the exact costs, and the rights you permanently lose.
The Income Tax Act prescribes different deadlines for different categories of taxpayers. Here is the complete schedule:
| Taxpayer Category | Due Date | Section |
|---|---|---|
| Salaried Individuals / HUFs (no audit) | 31 July 2026 | 139(1) |
| Businesses requiring Tax Audit (Sec 44AB) | 31 October 2026 | 139(1) |
| Transfer Pricing cases (international transactions) | 30 November 2026 | 139(1) |
| Revised Return (correction of original) | 31 December 2026 | 139(5) |
| Belated Return (missed original deadline) | 31 December 2026 | 139(4) |
| Updated Return (with additional tax) | 31 March 2028 | 139(8A) |
Missing the deadline triggers a cascade of financial consequences. Here is the exact breakdown:
| Your Total Income | Late Fee Amount | Deadline |
|---|---|---|
| Above ₹5 Lakh | ₹5,000 | Filed between 1 Aug – 31 Dec 2026 |
| Up to ₹5 Lakh | ₹1,000 | Filed between 1 Aug – 31 Dec 2026 |
| Below basic exemption limit | ₹0 (No penalty) | Filing is optional |
If you have any tax remaining to be paid (i.e., self-assessment tax), you will be charged 1% per month (or part of a month) simple interest on the outstanding tax amount. This runs from the original due date (31 July) until the actual date you file the return.
If your outstanding tax is ₹50,000 and you file on 15 October 2026 (2.5 months late), Section 234A interest = ₹50,000 × 1% × 3 months = ₹1,500. Part months are counted as full months.
If you file a belated return (after the due date), you permanently lose the ability to carry forward the following losses:
| Loss Type | On-Time Filing | Late Filing |
|---|---|---|
| Capital Losses (STCL / LTCL) | Carry forward 8 years ✅ | Lost forever ❌ |
| Business Losses | Carry forward 8 years ✅ | Lost forever ❌ |
| Speculation Losses | Carry forward 4 years ✅ | Lost forever ❌ |
| House Property Loss (up to ₹2L) | Carry forward 8 years ✅ | Still allowed ✅ |
| Depreciation (unabsorbed) | Carry forward indefinitely ✅ | Still allowed ✅ |
If you traded stocks, sold mutual funds at a loss, or have business losses this year — filing before 31 July is non-negotiable if you want to use those losses in future years.
Under Section 115BAC, salaried taxpayers can switch between Old and New Regime when they file their ITR. However, if you file a belated return, you cannot opt out of the default New Regime for that year. You're stuck with whichever regime was applied by your employer during TDS deduction.
From AY 2022-23 onwards, the government shortened the belated return window. If you do not file by 31 December 2026, you cannot file a return for FY 2025-26 at all — except through the Updated Return route (Section 139(8A)), which comes with an additional 25-50% tax penalty and must be filed within 24 months of the end of the AY.
Even after 31 December 2026, you can file an Updated Return (ITR-U) up to 31 March 2028. But this comes at a steep cost:
| When Filed | Additional Tax |
|---|---|
| Within 12 months of end of AY (by 31 Mar 2027) | 25% additional tax on the amount due |
| Between 12-24 months (1 Apr 2027 – 31 Mar 2028) | 50% additional tax on the amount due |
The Updated Return can only be used to increase your tax liability — you cannot claim a refund through it.
| Date | Event | Consequence |
|---|---|---|
| 31 Jul 2026 | Original Due Date | No penalty if filed on time |
| 1 Aug 2026 | Belated Return starts | ₹5,000 penalty + 1% monthly interest + loss carry-forward gone |
| 31 Dec 2026 | Last date for belated/revised return | Final chance to file normally |
| 1 Jan 2027 | Window closes | Cannot file regular return anymore |
| 31 Mar 2028 | Last date for Updated Return | Must pay 25-50% additional tax |
Even if you owe no tax (e.g., the 87A rebate makes your tax zero), you are still mandatorily required to file ITR if:
