Missing the income tax return filing deadline can result in penalties, loss of certain deductions, and the inability to carry forward losses. Understanding the key dates and planning your filing accordingly is crucial for every taxpayer in India. Here’s your complete guide to ITR filing deadlines for the assessment year 2026-27.
Key ITR Filing Dates for AY 2026-27
The financial year 2025-26 runs from April 1, 2025 to March 31, 2026. The income earned during this period is reported in your ITR for the assessment year 2026-27. The standard deadline for filing ITR for individuals and HUFs who are not required to get their accounts audited is July 31, 2026. For individuals and businesses requiring tax audit under Section 44AB, the deadline is October 31, 2026. For businesses requiring transfer pricing reports, the deadline is November 30, 2026.
Consequences of Missing the Deadline
Filing after the due date has several financial and legal implications. Late filing fee under Section 234F applies — if your total income exceeds ₹5 lakh, you must pay ₹5,000 as a late filing fee. If your income is below ₹5 lakh, the fee is ₹1,000. Interest under Section 234A is charged at 1% per month on the unpaid tax amount from the due date until the date of filing.
You lose the ability to carry forward certain losses. Business losses, capital losses, and losses under other sources (except house property loss) cannot be carried forward if the return is filed after the due date. Loss from house property can still be carried forward even with a belated return.
Deductions under sections 80C to 80U cannot be claimed if the return is filed beyond the updated return deadline. The due date for filing a belated return is December 31 of the assessment year, and for filing an updated return, it’s March 31 of the assessment year + 2 years.
Types of ITR Returns by Filing Date
Original Return (Filed by Due Date)
Filed on or before July 31, 2026. All deductions, exemptions, and loss carry-forward provisions are available. No late filing fee applies. This is the ideal scenario — always aim to file your original return before the deadline.
Belated Return (Filed After Due Date)
Can be filed until December 31, 2026. Late filing fee of ₹1,000 or ₹5,000 applies. Interest under 234A applies if taxes are due. Cannot carry forward certain losses. Deductions are still available under the belated return. A belated return can be revised until March 31, 2027.
Revised Return
If you discover an error or omission in your original or belated return, you can file a revised return. The deadline for revision is December 31, 2026 (for original returns filed by due date) or March 31, 2027 (as per the extended timeline). There is no limit on the number of revisions, but each revised return must be filed before the deadline.
Updated Return (ITR-U)
Introduced in 2022, the updated return allows you to file or update your return within 24 months from the end of the relevant assessment year. For AY 2026-27, this means you can file ITR-U until March 31, 2029. An additional tax of 25% is payable if filed within 12 months, and 50% if filed between 12-24 months. You can only declare additional income (not reduce income) through ITR-U.
Tips for Filing on Time
Start early — don’t wait until July to begin gathering documents. Your Form 16 is usually available by June 15. Check your Form 26AS and AIS as soon as they’re available. Pre-validate your bank account on the e-filing portal. Choose Aadhaar OTP verification for instant e-verification. Keep digital copies of all investment proofs. If your case is complex, engage a CA early to avoid the last-minute rush.
