the due date for your income tax return depends on who you are and whether your accounts need an audit. here are the dates for assessment year 2026-27 (financial year 2025-26).

ITR Filing Deadlines and Penalties

Due Dates at a Glance

note: the 31 august date for non-audit ITR-3/ITR-4 reflects the current position for ay 2026-27 and may be confirmed by a cbdt notification; the statutory baseline is 31 july.

What If You Miss the Deadline?

• you can still file a belated return up to 31 december 2026, with a late fee under section 234f (up to ₹5,000) and interest under section 234a;
• you lose the ability to carry forward certain losses;
• after 31 december, an updated return (ITR-U) is possible later but with additional tax.

Penalty and Interest for Missing the ITR Due Date

• section 234f late fee: ₹5,000 if you file after the due date, reduced to ₹1,000 if your total income does not exceed ₹5 lakh; no fee if your income is below the basic exemption limit;
• section 234a interest: 1% per month (or part of a month) on any unpaid tax, from the day after the due date until you actually file;
• section 234b interest: 1% per month where you paid less than 90% of your tax as advance tax during the year;
• section 234c interest: 1% per month for shortfall or deferment of the quarterly advance-tax instalments.

Already Missed the ITR Last Date? Here's What to Do

• file a belated return under section 139(4) as soon as possible — you have until 31 december 2026 for ay 2026-27, with the 234f fee and 234a interest above;
• clear any outstanding tax first, so the 234a and 234b interest stops accruing;
• if you also miss 31 december 2026, an updated return (ITR-U) under section 139(8A) is available up to 31 march 2031, but it carries additional tax of 25%–70% over the normal liability;
• if a refund is due and no tax is payable, no 234f fee applies — but you still need to file to claim the refund.

Don't Wait for the Deadline

filing early means a faster refund and time to fix any mismatch in your form 26as / ais. if your case is even slightly complex — capital gains, multiple incomes, nri status — get it reviewed well before the date.
