Income Tax Return Due Dates for AY 2026-27: A Complete Guide

For years, most taxpayers only had to remember one date, 31 July. That's no longer true. Starting this assessment year, the due date depends on which ITR form applies to you, and Budget 2026 has introduced a genuine staggering of deadlines rather than one common cutoff for everyone. Here's a clear breakdown of what's due when.

Due by 31 July 2026:

This remains the deadline for individuals and entities that don't require a tax audit and typically file ITR-1 or ITR-2. This covers:

• Salaried individuals and pensioners, including those with salary or pension income up to ₹50 lakh
• Taxpayers with income from up to two house properties
• Individuals earning capital gains from the sale of equity shares, mutual funds, or property, but with no business income (usually filing ITR-2)
• Anyone whose accounts are not required to be audited under the Income Tax Act and who has no business or professional income to report

If this is your category, 31 July 2026 remains your operative deadline, exactly as it has been in past years.

Due by 31 August 2026:

This is the genuinely new development for AY 2026-27. Previously, business and professional taxpayers not subject to audit still had to file by 31 July along with everyone else. Budget 2026 has now carved out an extra month for this group, so taxpayers filing ITR-3 or ITR-4 without a mandatory audit requirement get until 31 August 2026. This includes:

• Freelancers and consultants
• Small businesses and professionals whose turnover falls below the audit threshold
• Presumptive taxation filers under Sections 44AD, 44ADA, or 44AE who use ITR-4

The stated rationale behind the extra month is to give this category more breathing room to close their books and complete reconciliations, something salaried taxpayers with straightforward Form 16 income don't need as much time for.

Due by 30 September 2026:

This date matters specifically for entities whose accounts require a statutory audit. The Tax Audit Report itself, filed by the auditor rather than the taxpayer, is due one month ahead of the return filing deadline for audit cases. So if you fall into the audit category below, your auditor's report needs to be filed by 30 September 2026, ahead of your own return.

Due by 31 October 2026:

This is the general due date for taxpayers whose books of account are required to be audited under the Income Tax Act. It applies to:

• Companies
• Partnership firms and LLPs subject to audit
• Individuals and businesses whose turnover or receipts cross the audit threshold under Section 44AB

Due by 30 November 2026:

Taxpayers who have entered into international transactions or specified domestic transactions requiring a transfer pricing report under Section 92E get the longest runway, until 30 November 2026. This category typically covers larger businesses and multinational entities with related-party cross-border dealings.

What Happens If You Miss Your Deadline:

Missing your applicable due date doesn't mean you're locked out of filing, but it does come with costs.

Belated return. You can still file until 31 December 2026 as a belated return. This attracts a late filing fee under Section 234F, up to ₹5,000 depending on your income level, along with interest on any unpaid tax under Section 234A. A more significant consequence is that filing late generally forecloses your ability to opt for the old tax regime for that year; you'll be taxed under the new regime by default, losing access to deductions such as 80C, 80D, HRA, and home loan interest under Section 24(b).

Revised return. If you've already filed on time but discover an error or omission, Budget 2026 has extended the window to file a revised return from the earlier 31 December cutoff to 31 March 2027. This gives taxpayers a genuinely longer runway to correct mistakes discovered after the fact, whether due to a late Form 16 correction, updated Form 26AS, or a mismatch in the Annual Information Statement.

Updated return (ITR-U). For taxpayers who miss filing altogether or later discover undisclosed income, the updated return facility remains available for up to four years from the end of the relevant assessment year. For AY 2026-27, that puts the outer limit for filing an ITR-U at 31 March 2031, though filing later within that window typically means paying additional tax as a penalty for the delay.

A Quick Reference Table

The Bottom Line:

The single biggest change this year is that your ITR form, not just your income level, now determines your deadline. A salaried employee and a freelancer with identical income levels now file a month apart. Given that filing late costs you both money under Section 234F and the option to use the old tax regime, it's worth confirming which ITR form applies to you early, rather than assuming 31 July is your date by default.
