ITR Filing Due Dates AY 2026-27 — At a Glance

Who Must File ITR by August 31, 2026?

The August 31 deadline applies to the following taxpayers for AY 2026-27:

• Salaried individuals (ITR-1 / ITR-2)
• Individuals with income from house property, capital gains, or other sources
• HUFs (Hindu Undivided Families) not requiring tax audit
• Freelancers and professionals opting for presumptive taxation under Section 44ADA
• Small businesses under Section 44AD (turnover up to ₹3 crore)
• NRIs with taxable income in India
• Individuals with F&O trading income (non-audit cases)

Penalty for Late ITR Filing — Section 234F

If you miss the August 31, 2026 due date and file after that (but before December 31, 2026), a late filing fee is levied under Section 234F:

Interest for Late Filing — Section 234A

Apart from the late filing fee, if there is any tax liability remaining unpaid after August 31, 2026, you must pay interest at 1% per month (or part of a month) under Section 234A until the tax is paid. This applies from the original due date to the actual date of filing.

Example: If you have ₹50,000 in unpaid tax and file 3 months late, interest = ₹50,000 × 1% × 3 = ₹1,500.

Consequences of Missing the ITR Due Date

• Late filing fee: ₹1,000 to ₹5,000 under Section 234F
• Interest on unpaid tax: 1% per month under Section 234A
• Loss carry-forward denied: You cannot carry forward capital losses, business losses, or speculative losses if the ITR is not filed on time
• Refund delayed: Late filers receive their refund with interest under Section 244A, but refund processing is slower
• Notice risk: Non-filers with taxable income face a higher probability of receiving an income tax notice

Belated Return — Filing After August 31, 2026

Even if you miss the August 31, 2026 due date, you can still file a belated return under Section 139(4) up to December 31, 2026. The late filing fee under Section 234F will apply. However, you lose the right to carry forward losses (except house property loss).

Updated Return (ITR-U) — Last Resort

If you miss even the December 31 belated return deadline, you can still file an Updated Return (ITR-U) under Section 139(8A) within 2 years from the end of the relevant assessment year — i.e., up to March 31, 2029 for AY 2026-27.

ITR-U is only for paying additional tax — you cannot claim refunds or carry forward losses through this route. An additional tax of 25% (if filed within 1 year) or 50% (if filed in the 2nd year) on the aggregate tax and interest is levied.
