Missed the ITR deadline? Belated return options, Section 234F late fee and capital-loss rules for AY 2026-27 explained
Quick Answer

The ITR-1/ITR-2 deadline of 31 July 2026 was not extended. If you missed it, you can still file a belated return under Section 139(4) until 31 December 2026. The late fee is ₹5,000 (₹1,000 if income ≤ ₹5 lakh; nil if below exemption). One permanent cost: capital losses from FY 2025-26 cannot be carried forward — but you can still set them off against this year's gains in the belated return. Refunds are still claimable. Act before 31 December; after that, only an ITR-U applies — which cannot claim a refund.

Date-confusion alert: Several social media posts and articles are circulating a "deadline extended to 15 September" claim. That applied to AY 2025-26 (last year). For AY 2026-27 (FY 2025-26), no CBDT extension was announced. The 31 July 2026 deadline stood. The information below reflects that confirmed position.

You Missed the Deadline — Here Is What That Means

The 31 July 2026 deadline for salaried individuals filing ITR-1 and ITR-2 for AY 2026-27 has passed. The Central Board of Direct Taxes did not announce an extension. If your return was not filed by midnight on 31 July, it is now late — but it is not over.

Under Section 139(4) of the Income Tax Act, 1961, you can file a belated return until 31 December 2026. A belated return is exactly the same ITR form filed on the same e-filing portal (incometax.gov.in) — the only differences are the late fee, possible interest on outstanding tax, and certain consequences that cannot be undone. Understanding those differences is what this article is about.

Section 234F: The Late Fee You Will Pay

Filing after 31 July 2026 triggers a late fee under Section 234F. The amount depends on your total income:

Your Total Income (FY 2025-26) Section 234F Late Fee
Above ₹5 lakh ₹5,000 (flat; payable at time of filing)
₹5 lakh or below ₹1,000 (capped)
Below the basic exemption limit Nil (no tax payable = no late fee)

The late fee is a flat charge — it is the same whether you file on 1 August or on 31 December. There is no scaling of the fee the longer you wait within the belated-return window. The incentive to file quickly is the interest calculation below, not the fee.

Section 234A: Interest on Outstanding Tax

Section 234A levies interest at 1% per month (or part of a month) on any tax that was outstanding as of 31 July 2026, running from 1 August 2026 until the date you actually file the return.

If your entire tax liability was covered by TDS deducted by your employer and/or advance tax paid during the year — leaving zero outstanding — Section 234A does not apply. Most salaried employees who are owed refunds or whose TDS fully covered their liability will not face this interest charge at all.

For those who do have outstanding tax, the calculation is straightforward:

Example: Outstanding tax = ₹10,000. Belated return filed on 15 September 2026 (2 calendar months after 31 July, counted as 2 months under the part-of-month rule). Interest = ₹10,000 × 1% × 2 = ₹200.

The key action here: pay the outstanding tax via Challan 280 before filing the return. Payment stops the interest clock; the return can be filed shortly after. Waiting to file and then paying all at once means interest runs until the filing date, not the payment date.

The Capital-Loss Carryforward: This Is the Real Cost

For anyone who booked capital losses in FY 2025-26 — from equity stocks, equity mutual funds, property sales, or any other capital asset — the missed deadline has a consequence that a belated return cannot fix.

Capital losses can no longer be carried forward to future years. To carry forward a capital loss from FY 2025-26 to set off against capital gains in FY 2026-27 or later, the return must have been filed by 31 July 2026. Missing that date by even one day permanently extinguishes the carry-forward right for those losses. Filing a belated return does not restore it.

This is the most consequential cost of a late filing for investors. If you had significant equity losses this year and planned to carry them forward to offset future gains, that tax planning opportunity is gone for FY 2025-26.

However — and this precision matters — you can still set off those losses against capital gains earned in FY 2025-26 itself within the belated return. The loss of carry-forward refers specifically to future years; current-year set-off in the same return remains available. If you have both short-term gains and short-term losses in FY 2025-26, netting them in your belated return is still permitted.

Business Losses and House Property Loss

The same carry-forward restriction applies to business and professional losses: if the ITR was not filed by 31 July, those losses also cannot be carried forward to future years.

The exception is house property loss. A loss from house property (typically the interest on a self-occupied home loan in excess of rental income) can be carried forward even if the return is filed as a belated return. This is one category of loss that survives a late filing.

Your Refund Is Not Lost

If you are owed a refund — the majority of salaried employees whose employer deducted excess TDS — filing late does not forfeit your right to that refund. A belated return filed by 31 December 2026 can claim a full refund.

Two nuances to know. First, processing timelines will be longer; a return filed in August will typically be processed later than one filed in July. Second, refund interest under Section 244A accrues only from the date you file the return, not from 1 April. The later you file, the less interest you accumulate on your own refund — though for most salaried filers with refunds of a few thousand rupees, this interest is modest.

The hard deadline is what matters most: if you want your refund, you must file by 31 December 2026. After that, the ITR-U route does not permit refund claims.

What Happens After 31 December 2026: The ITR-U Route

If you do not file the belated return by 31 December 2026, your only remaining option is an Updated Return (ITR-U) under Section 139(8A). Following the Finance Act 2025, ITR-U can be filed for up to 48 months (four years) from the end of the assessment year — but the additional tax climbs the longer you wait, and it cannot be used to claim a refund.

Route Available Until Refund Claimable? Additional Cost
Belated return (Section 139(4)) 31 December 2026 Yes ₹5,000 / ₹1,000 late fee + 234A interest (if outstanding tax)
ITR-U, within 12 months of AY end (Section 139(8A)) 31 March 2028 No 25% of aggregate tax + interest, above the tax already due
ITR-U, 12–24 months 31 March 2029 No 50% of aggregate tax + interest
ITR-U, 24–36 months 31 March 2030 No 60% of aggregate tax + interest
ITR-U, 36–48 months 31 March 2031 No 70% of aggregate tax + interest

If you have additional income to declare and no refund to claim, ITR-U is a legitimate path. But for anyone owed a refund — including most TDS-deducted salaried employees — the belated return by 31 December is the only route that delivers it.

Other Deadlines Still Open — Do Not Miss These Too

The 31 July deadline applied specifically to salaried filers (ITR-1, ITR-2). Other categories still have live deadlines:

Taxpayer Category Form Deadline Status
Salaried / no business income ITR-1, ITR-2 31 Jul 2026 Passed — belated by 31 Dec 2026
Business / professional income, no audit required ITR-3, ITR-4 31 Aug 2026 ALIVE — 28 days left
Audit cases (business/profession) ITR-3 etc. 31 Oct 2026 Alive
Transfer pricing cases 30 Nov 2026 Alive

If you have any business or freelance income alongside your salary, your filing may fall under ITR-3 or ITR-4, and the 31 August deadline is still open. Review your income profile carefully before assuming you are in the "belated" bracket.

What to Do Right Now — Action Checklist

  • Compute your outstanding tax — check your Form 26AS and AIS on the income tax portal to identify any TDS shortfall. If all tax was covered, Section 234A does not apply.
  • Pay outstanding tax via Challan 280 before filing — this stops the 234A interest clock immediately. Payment and filing do not have to happen on the same day.
  • File the belated return on the income tax portal — the process is identical to a regular ITR; select the correct form (ITR-1 for salaried with simple income; ITR-2 if you have capital gains, more than one house, foreign income, etc.). The portal will prompt you to pay the 234F fee at the time of submission.
  • Budget the late fee — ₹5,000 if income exceeds ₹5 lakh; ₹1,000 if at or below ₹5 lakh. This is not avoidable.
  • Accept the capital-loss carryforward consequence — if you had capital losses this year, accept that the carry-forward to future years is gone. Still file: you can still set off those losses against this year's gains in the return itself, which reduces your tax for FY 2025-26.
  • File before 31 December 2026 — do not let the belated-return window expire. After that, only ITR-U applies, costs significantly more, and cannot claim a refund.
Bottom Line

Missing 31 July costs you ₹5,000 in late fee (₹1,000 if income ≤ ₹5 lakh), possible 234A interest on outstanding tax, and — most painfully for investors — the right to carry forward FY 2025-26 capital losses to future years. None of that changes by waiting. File the belated return as soon as you can, pay any outstanding tax first, and do it before 31 December 2026. After that date, the ITR-U path is costlier and cannot get you a refund.

Frequently Asked Questions

What is a belated return and what is the last date to file for AY 2026-27?
A belated return is an income tax return filed after the original due date, under Section 139(4) of the Income Tax Act, 1961. For AY 2026-27 (FY 2025-26), the original deadline of 31 July 2026 has passed with no CBDT extension. You can still file a belated return until 31 December 2026. This filing is legally valid, entitles you to a refund (if applicable), and carries late-fee liability under Section 234F.
What Section 234F late fee applies if I file my ITR after 31 July 2026?
Under Section 234F, the late fee is ₹5,000 if your total income exceeds ₹5 lakh, and ₹1,000 if your total income is ₹5 lakh or below. No late fee applies if your total income is below the basic exemption limit (i.e., no tax is payable). This fee is a flat charge payable at the time of filing — it is not affected by how late within the August–December window you file.
Can I still carry forward capital losses if I file a belated return?
No. Capital losses from FY 2025-26 — from stocks, equity mutual funds, property, or other capital assets — cannot be carried forward to future years if the ITR was not filed by 31 July 2026. This is a permanent consequence; filing a belated return does not restore the carry-forward right. However, you can still set off those losses against capital gains earned in FY 2025-26 itself within the belated return. Business and professional losses also cannot be carried forward; house property loss is the exception and can still be carried forward even in a belated return.
Can I still claim a tax refund in a belated return?
Yes. A belated return filed by 31 December 2026 can claim a tax refund. Missing the 31 July deadline does not forfeit your refund entitlement. However, refund interest under Section 244A runs only from the date you file the return — not from 1 April — so the longer you delay, the more interest you forgo. After 31 December 2026, you must use an Updated Return (ITR-U), which cannot be filed to claim a refund at all. If you are owed a refund, file before 31 December.
What happens if I miss the belated-return deadline of 31 December 2026?
After 31 December 2026, the only option is an Updated Return (ITR-U) under Section 139(8A). Following the Finance Act 2025, ITR-U can be filed for up to 48 months (four years) from the end of the assessment year — for AY 2026-27, until 31 March 2031 — but the additional tax rises the longer you wait: 25% of aggregate tax and interest within 12 months, 50% within 24 months, 60% within 36 months, and 70% within 48 months. Critically, ITR-U cannot be used to claim a refund — it is only for declaring additional income and paying more tax. If you are owed a refund, or want to avoid the extra 25% to 70% surcharge, file the belated return before 31 December 2026.
