Beware! A single mistake in your ITR could lead to a penalty of up to 200%—know these 5 strict rules from the Income Tax Department..

ITR Filing (AY 2026-27): Late Fees and Penalties – If you are preparing to file your Income Tax Return (ITR) for the financial year 2025-26, simply filing the return does not absolve you of all responsibilities. Failure to adhere to Income Tax Department regulations, providing incorrect information, or missing the deadline can prove costly.

Consequences range from late fees for minor errors to hefty penalties of up to 200% for tax evasion or providing false information. The deadline for filing ITR for individuals and the salaried class (not subject to audit) is July 31, 2026. Let us understand five strict rules and penalties that every taxpayer must be aware of.

1- Penalty of ₹5,000 for missing the July 31 deadline

If you fail to file your ITR by the July 31, 2026 deadline, a late filing fee will be levied under Section 234F. If your total income is up to ₹5 lakh, the maximum late fee is capped at ₹1,000. However, if your total income exceeds ₹5 lakh, the late fee will be ₹5,000.

2. Penalty for filing a late revised return

If you make an error while filing your ITR and rectify it long after the deadline has passed, you may face a penalty. Filing a revised return more than nine months but within twelve months after the end of the assessment year could attract a fee ranging from ₹1,000 to ₹5,000 under Section 234-I.

3. Tax penalty of up to 200% for concealing income or providing false information

This is one of the Income Tax Department's strictest regulations. If you conceal your actual income or provide incorrect information in your ITR, a penalty of 50% of the tax payable on the under-reported income will be imposed under Section 270A. A penalty of up to 200% of the outstanding tax can be imposed for providing incorrect or false information.

4. 100% penalty on cash transactions exceeding ₹2 lakh

Accepting a cash transaction of ₹2 lakh or more in a single day or as part of a single transaction constitutes a violation of Section 269ST. A penalty equal to the entire cash amount received may be imposed by the Income Tax Department.

5. Strict action for non-payment of self-assessment tax

If, based on your calculations, any tax is payable before filing your ITR and you fail to pay it, the Assessing Officer (AO) can impose an additional penalty equal to the outstanding tax amount under Sections 140A and 221.

Over 3 crore ITRs filed; do not wait for the last date

According to the Income Tax Department, more than 3 crore ITRs have been filed for the Assessment Year 2026-27 as of July 22, 2026. The pace of filing has accelerated as the deadline approaches. To assist taxpayers, the Income Tax Department has decided to keep its e-filing and CPC helplines operational 24x7 from 8:00 AM on July 25 until 11:59 PM on July 31.
