ITR Filing Deadline AY 2026-27: Full Due Date Schedule

Quick answer: For AY 2026-27 (FY 2025-26 income), salaried individuals and non-business filers (ITR-1, ITR-2, most non-audit ITR-5 entities) file by 31 July 2026. Non-audit business owners and professionals (ITR-3, ITR-4, presumptive taxation) get an extra month — 31 August 2026. Audit cases move to 31 October 2026, and transfer pricing cases (Form 3CEB) to 30 November 2026. Belated returns are accepted until 31 December 2026, revised returns until 31 March 2027, and Updated Returns (ITR-U) until 31 March 2031.

For as long as most Indian taxpayers can remember, July 31 has been the date everyone circled, dreaded, and usually scrambled to meet anyway. That single, universal deadline is gone. Starting with Assessment Year 2026-27 (income earned in FY 2025-26), the filing calendar has been split by taxpayer category, and not knowing which date applies to you is now a genuine way to end up paying a penalty for a deadline you didn't realise existed.

Filing for AY 2026-27 is already open — the CBDT notified all ITR forms back on March 30, 2026, and ITR-1, ITR-2, and ITR-4 are live for e-filing right now. With the July 31 cutoff roughly six weeks away, this is the right moment to figure out which date is actually yours.

Why the Calendar Got Split in the First Place

The change came straight from Finance Minister Nirmala Sitharaman's Budget 2026 speech on February 1. Her reasoning was simple: a salaried employee with one Form 16 and a small business owner reconciling a full year of invoices, GST returns, and presumptive income calculations are not doing comparable amounts of work, so cramming both into the same end-of-July deadline never made sense. It also meant the e-filing portal got hammered every year in the last week of July, regardless of who actually needed the extra time. Splitting the calendar spreads that load out gives the more complex filers room to breathe.

One more wrinkle worth knowing: the new Income Tax Act, 2025, technically came into force on April 1, 2026, but it doesn't touch this filing cycle. Because AY 2026-27 covers income earned in FY 2025-26 — a period that ended before the new Act existed — your return this year is still governed entirely by the old Income Tax Act, 1961. The new Act only kicks in for income earned from April 2026 onward, which you'll file in 2027.

The Core Filing Schedule

Here's how the dates actually break down by category:

• 31 July 2026 — Salaried individuals, pensioners, and anyone filing ITR-1 or ITR-2 (capital gains, multiple house properties, foreign assets, but no business income). Most non-audit ITR-5 filers — partnership firms, LLPs, AOPs, and BOIs that don't require an audit — share this same date. This is the deadline most people already know and the one that hasn't moved.
• 31 August 2026 (new) — Non-audit business owners and professionals filing ITR-3 or ITR-4, including those under presumptive taxation. This is the date that genuinely changed, and it's the one most likely to catch people off guard.
• 31 October 2026 — Anyone whose accounts require a mandatory tax audit under Section 44AB, including companies and larger firms.
• 30 November 2026 — Taxpayers with international transactions or specified domestic transactions who need to file Form 3CEB for transfer pricing.

One narrow edge case is still genuinely unsettled in the way professional sources describe it: certain business trusts and investment funds were referenced separately in the Finance Minister's Budget speech, and it isn't fully clear yet whether every such entity follows the July 31 ITR-5 date or the August 31 window. If that's your structure, confirm the specific date on the income tax e-filing portal before filing. For everyone else — salaried individuals, standard firms/LLPs, non-audit businesses and professionals, and audit cases — the dates above are settled.

The Deadlines Before the Deadline

If your accounts need an audit, July and August aren't really your problem — September and October are. The tax audit report (Forms 3CA/3CB along with 3CD) has to be uploaded by your chartered accountant by 30 September 2026, and that has to be done before your own return can go in by October 31. If your business has cross-border dealings, the transfer pricing audit report needs to be filed by 31 October 2026, ahead of the November 30 return deadline.

In practice, this means audit-case businesses should be locking in their CA well before September, not scrambling in October. Once audit season opens, the CAs with good track records fill up fast, and a late start on your end quietly becomes a late filing on theirs.

If You Miss It: Belated, Revised, and Updated Returns

Missing the original date isn't the end of the road, but it isn't free either.

A belated return under Section 139(4) can still be filed up to 31 December 2026, with a late fee attached. If you filed on time but later spot a mistake — a missed deduction, a wrong bank account number, an income figure that doesn't match your AIS — you can fix it through a revised return any time before 31 March 2027.

There's also a longer safety net called the Updated Return (ITR-U), running all the way to 31 March 2031 — four years from the end of the assessment year. It's there for taxpayers who realize, well after the fact, that they missed reporting some income, even after both the belated and revised return windows have shut. It's meant for honest correction, not as a substitute for filing on time, and it comes with its own additional tax cost that grows the longer you wait to use it.

What Missing It Actually Costs You

The individual penalties don't sound dramatic, but they add up faster than people expect.

Miss the original deadline and Section 234F kicks in — a flat ₹1,000 if your total income is up to ₹5 lakh, ₹5,000 if it's above that. On top of the fee, Section 234A adds interest at 1% per month on any tax still outstanding, calculated from the original due date, not from whenever you actually get around to filing.

The part most people underestimate is the loss of carry-forward rights. If you're sitting on capital losses or business losses you were planning to offset against future gains, filing late forfeits that right completely. For someone with a meaningful stock market loss or a rough business year, that's often a bigger financial hit than the late fee itself — and it's permanent.

A Few Quick Answers

Is the August 31 date locked in, or could it shift? It's the rule under Budget 2026, but the department has extended deadlines in past years for technical glitches or natural disasters (the AY 2025-26 deadline moved from July 31 to September 15, and the audit report deadline that year shifted from September 30 to October 31 after flood-related representations). Plan around August 31. Don't bet on an extension.

What decides which ITR form applies to me — my job title or my income type? Income source, not job title. Salary plus capital gains alone usually means ITR-1 or ITR-2. Any business or professional income, even something small on the side, pushes you into ITR-3 or ITR-4.

Does a belated return still let me claim a refund? Yes, but processing typically takes longer, and the loss carry-forward restriction applies regardless of whether a refund is involved.
