Missed the ITR Deadline? Exactly What to Do Now (AY 2026-27)
- You can still file a belated ITR for AY 2026-27 up to 31 December 2025 under Section 139(4) — the deadline being missed is not the end.
- A late fee of ₹1,000 (income ≤ ₹5 lakh) or ₹5,000 (income > ₹5 lakh) applies under Section 234F, plus interest on any tax due under Sections 234A, 234B, and 234C.
- Certain losses — especially capital gains and business losses — cannot be carried forward if you file late, so speed matters.
If you missed the 31 July 2025 ITR deadline for AY 2026-27, you have not lost your chance to file. You can submit a belated return under Section 139(4) of the Income Tax Act any time up to 31 December 2025. You will owe a late fee and possibly some interest, but the process itself is almost identical to filing on time. Here is exactly what to do, in plain steps, with real numbers so you know what it costs you.
What "Belated Return" Actually Means
A belated return is simply a regular ITR filed after the original due date but within the extended window the law allows. For AY 2026-27 (income earned April 2025 – March 2026), that window closes on 31 December 2025. After that date, you cannot file at all unless the Income Tax Department issues a notice — in which case you respond to the notice instead.
Two important restrictions come with a belated return:
- Losses you cannot carry forward: Business losses under the head "Profits and Gains of Business or Profession" and most capital gains losses cannot be carried forward if you file late. House property losses and unabsorbed depreciation are still allowed.
- No revised return after 31 December: Once the belated-return window shuts, you cannot revise the return either. Get it right the first time.
The Exact Penalties and Interest You Will Pay
Three charges can apply. Understanding each one prevents surprises.
| Charge | Section | Rate / Amount | Who It Hits |
|---|---|---|---|
| Late filing fee | 234F | ₹1,000 if total income ≤ ₹5 lakh; ₹5,000 if total income > ₹5 lakh | Almost everyone filing late (nil if income is below basic exemption) |
| Interest on unpaid tax | 234A | 1% per month (simple) on tax due after the original due date | Anyone who had a balance tax payable on 31 July 2025 |
| Interest on advance tax shortfall | 234B / 234C | 1% per month on the shortfall in advance tax instalments | Those whose advance tax was less than 90% of total tax liability |
Good news for salaried employees with no other income: If your employer deducted TDS correctly throughout the year, your "tax due" is likely zero. In that case, Section 234A interest does not apply. You only pay the flat ₹5,000 (or ₹1,000) late fee.
Worked Example: What It Actually Costs on a ₹12,00,000 Salary
Suppose you are a salaried person with gross income of ₹12,00,000 for FY 2025-26. You chose the new tax regime. Your employer deducted TDS of ₹72,500 during the year, which exactly equals your tax liability after the standard deduction and applicable cess. You file on 30 November 2025 — four months late.
- Late filing fee (Section 234F): ₹5,000 (income > ₹5 lakh). This is a flat fee — it does not grow with time.
- Section 234A interest: ₹0 — because your full tax was already paid via TDS. There is no balance outstanding.
- Section 234B / 234C: ₹0 — TDS counts as advance tax; no shortfall.
- Total extra cost: ₹5,000.
Now change one fact: suppose your employer under-deducted and you still owe ₹20,000 in tax. You file on 30 November 2025, paying that ₹20,000 now.
- Section 234A interest: 1% × ₹20,000 × 4 months = ₹800
- Section 234F late fee: ₹5,000
- Total extra cost: ₹5,800
The interest is surprisingly small when the outstanding tax is modest. The real financial damage from filing late is the loss of carry-forward losses, not the fee itself.
Step-by-Step: How to File Your Belated Return Now
- Gather your documents first. Download Form 26AS and the Annual Information Statement (AIS) from the income tax portal. Cross-check TDS credits. Collect salary slips, Form 16, bank interest certificates, and any capital gains statements from your broker.
- Pay any outstanding self-assessment tax. Log in to the tax portal, go to e-Pay Tax, and pay using Challan 280 (selecting "Self-Assessment Tax"). Note the challan number.
- Select the correct ITR form. Most salaried people use ITR-1 (only salary, one house property, interest income). Freelancers and small-business owners typically need ITR-3 or ITR-4. Choosing the wrong form is a common — and fixable — mistake, but fixing it wastes time.
- File online. Use the income tax portal or a guided tool like KyaTax's ITR wizard (belated-ready), which flags Section 234F fees and checks for carry-forward loss restrictions automatically.
- Select "139(4) – Belated Return" in the filing section. Do not accidentally select 139(1); the portal should prompt you, but verify.
- E-verify within 30 days. An unverified return is treated as if it was never filed. Use Aadhaar OTP, net banking, or Demat account verification. This step is non-negotiable.
Common Mistakes People Make When Filing Late
1. Assuming the deadline is 31 March
Many people confuse the belated return deadline (31 December) with the end of the financial year (31 March). The belated return window closes three months before that. Waiting until February or March means you legally cannot file at all.
2. Not paying self-assessment tax before filing
The return gets filed but the tax payment is skipped. The portal may accept the return, but the ITD treats unpaid tax as arrears. Interest under 234A keeps accruing, and a demand notice follows.
3. Claiming carry-forward of capital losses on a belated return
A trader who made losses in stocks files late and still claims to carry forward those losses to next year. The law explicitly bars this. The ITD will reject the carry-forward claim even if the portal does not flag it immediately.
4. Filing the wrong ITR form because of a side income
A salaried person who earned ₹30,000 from freelance work files ITR-1 (which does not cover business income). The return is technically defective and can attract a notice. ITR-4 (Sugam) handles both salary and small business income under the presumptive scheme.
5. Forgetting to e-verify
The return is filed but the e-verification step is skipped — often because the person thinks the job is done once the form is submitted. Without e-verification within 30 days of filing, the return has no legal standing.
Special Situations: What If You Cannot File Even by 31 December?
If you genuinely miss the 31 December 2025 deadline — say, due to a medical emergency or being abroad — your only option is to wait for a notice from the Income Tax Department and respond to it, or to approach your Assessing Officer (AO) and request condonation of delay under Section 119(2)(b). This route involves submitting a written application explaining the genuine hardship. Approval is not guaranteed and is granted at the AO's discretion. Do not rely on this as a plan.
If you simply have not received your Form 16 yet from an employer, that is not a valid reason to wait. You can reconstruct salary income from your last few payslips and bank credits, file using those figures, and revise the return once Form 16 arrives — provided you are still within the 31 December window.

What is the last date to file a belated ITR for AY 2026-27?
The last date is 31 December 2025. After this date, you cannot file a belated return under Section 139(4) unless the Income Tax Department issues a notice or grants a specific condonation.
How much is the penalty for missing the ITR deadline?
The late filing fee under Section 234F is ₹5,000 if your total income exceeds ₹5 lakh, and ₹1,000 if your total income is ₹5 lakh or below. There is no fee at all if your income is below the basic exemption limit. Additional interest under Section 234A applies only if you had unpaid tax as of the original due date.
Can I still get a tax refund if I file a belated return?
Yes. Filing a belated return does not forfeit your refund. However, the Income Tax Department has the discretion to delay processing belated returns, and interest on refunds (under Section 244A) may be reduced depending on when you file.
Can I revise a belated return if I made a mistake?
Yes, but only until 31 December 2025 — the same deadline as the belated return itself. After that date, neither a fresh belated return nor a revised return can be filed. This is why it is important to file carefully the first time and revise quickly if you spot an error.
