Due Dates: The Individual Tax Calendar

Which date applies depends on what kind of return is being filed, not just the calendar year. For AY 2026-27, non-audit business and professional filers get a different date than salaried filers for the first time.

Income Tax Basics

Allowances and Perquisites

AY 2026-27 relates to income earned in FY 2025-26, assessed entirely under the 1961 Act. Due dates are subject to CBDT extension and can change after this was written. This article is for general information and does not constitute tax advice.

ITR Filing Due Dates

ITR-1 and ITR-2 (salaried, no business/professional income): 31 July 2026, not extended as things currently stand. ITR-3 and ITR-4 without audit: 31 August — new for AY 2026-27; previously this group shared the 31 July date. Taxpayers requiring a tax audit: 31 October, with the audit report itself (new Section 63, old Section 44AB) due a month earlier, by 30 September. Taxpayers requiring a transfer pricing report: 30 November. These dates are occasionally extended by CBDT notification — most recently for AY 2025-26, when 31 July moved to 15 September — but no extension has been announced for AY 2026-27 as things stand.

Belated, Revised, and Updated Returns

A return filed after the due date but by 31 December of the assessment year is belated; later than that generally can’t be filed short of specific relief. A revised return can correct a timely filing up to 31 March of the following year, or before assessment completes, whichever is earlier. Missing the original date brings a Section 234F late fee (₹1,000–₹5,000) and Section 234A interest (1% per month), and a belated return loses the ability to carry forward certain losses and can restrict switching between tax regimes for that year.

An Updated Return (ITR-U) allows additional income to be declared and additional tax paid within 48 months from the end of the relevant assessment year (extended from 24 months) — it exists to correct under-reporting, and cannot be used to claim a refund, reduce previously reported tax, or introduce a loss.

Advance Tax Due Dates

Where net tax liability after TDS exceeds ₹10,000 in a year, advance tax is paid in instalments:

Due date	Cumulative amount payable
15 June	15%
15 September	45%
15 December	75%
15 March	100%

Taxpayers under the presumptive scheme pay the full amount in a single instalment by 15 March instead of the staggered schedule. Sections 234B and 234C cover shortfall or deferment of advance tax, separate from Section 234A for late filing of the return itself.

FAQs: Due Dates

Has the 31 July 2026 deadline actually been extended?

Not as things currently stand; it remains 31 July 2026 for ITR-1 and ITR-2. Extensions are typically announced close to the original date, so it’s worth checking the e-filing portal directly if reading this near the deadline.

Why do ITR-3/ITR-4 non-audit filers get until 31 August this year?

This is the first year the two groups have had separate dates. Salaried and simple-income filers keep 31 July, while non-audit business and professional filers now get an extra month.

Can advance tax be skipped if TDS already covers most of the liability?

Yes. If what remains payable after TDS is ₹10,000 or less for the year, there’s no advance tax obligation at all.

Can an Updated Return be used to claim a refund that was missed?

No. It can only be used to report additional income and pay additional tax, not to claim a refund, reduce previously reported liability, or introduce a loss.

If the tax audit report is filed on time, does that automatically mean the ITR itself is also on time?

No, they’re separate filings with separate deadlines. A timely audit report doesn’t extend the ITR due date.

What happens if CBDT extends the deadline after a return has already been filed?

Nothing changes for that return. An extension benefits taxpayers who hadn’t yet filed by giving them more time.
