What is ITR-U (Updated Income Tax Return)?

ITR-U, also called an Updated Income Tax Return under Section 139(8A), is a helpful option for taxpayers who either did not file their ITR or made mistakes while reporting income earlier. It allows you to correct errors or add missing income details in your previous returns.

As per Budget 2025, you can file ITR-U within 4 years from the end of the relevant assessment year. This gives taxpayers extra time to fix their tax filings and stay compliant.

For example, if you missed filing your ITR for AY 2021–22 (FY 2020–21), you can still file an updated return until 31st March 2026. If you miss this final deadline, it may lead to penalties or legal issues.

Keep in mind, filing ITR-U involves paying additional tax (up to 70%) along with your due tax amount.

You can file ITR-U whether you:

• Did not file your ITR at all, or
• Filed it but made mistakes, or
• Filed a belated or revised return

Key Features of Updated Return (ITR-U)

For example, for FY 2020–21 (AY 2021–22), the last date is 31st March 2026.

File Only Once
You can file ITR-U only one time for a particular assessment year. After that, no more changes are allowed.

But you cannot use ITR-U to claim or increase a refund.

Extra Tax Charges

Rule for Notice Cases (Section 139(8A))

However, if later it is decided that the notice is not valid, then you can still file ITR-U within the 4-year limit.

Update in Section 140B
This section now clearly defines how much extra tax you need to pay for delayed filing.

Update in Rule 12AC
This rule has also been updated to match the new changes in ITR-U filing rules.

Who Should File ITR-U?

Any taxpayer can file an Updated Return under Section 139(8A), whether they have already filed their return or not. It is useful if there was any mistake, missing detail, or incorrect information in the earlier return.

You can file ITR-U in the following cases:

• You did not file your return earlier
• You missed reporting some income
• You selected the wrong income category (head of income)
• You need to reduce carried forward losses
• You need to reduce unabsorbed depreciation
• You need to correct tax credit under Sections 115JB/115JC
• You applied the wrong tax rate earlier

In short, ITR-U gives you a chance to fix errors and update your tax return correctly.

Who Cannot File ITR-U?

You cannot file an Updated Return (ITR-U) in the following situations:

• You have already filed an ITR-U for that year (only one time allowed)
• The updated return shows a loss
• It reduces your tax liability compared to the earlier return
• It increases your refund amount

Also, ITR-U is not allowed if:

• A search operation has been conducted under Section 132
• Your books or documents are seized under Section 132A
• A tax survey has been done under Section 133A
• Any assessment, reassessment, or revision is ongoing or already completed for that year

ITR-U Filing Deadline

The time limit to file an Updated Return (ITR-U) under Section 139(8A) has been increased from 2 years to 4 years starting April 2025 (as announced in Budget 2025–26).

This means you can now file ITR-U within 4 years from the end of the relevant assessment year.

For example, for FY 2023–24 (AY 2024–25), you can file an updated return till 31st March 2029.

ITR-U Late Filing Penalty

From April 2025, you can file an Updated Income Tax Return (ITR-U) within 4 years instead of 2 years.

However, if you file late, you will have to pay extra tax along with your normal tax and interest:

• Filed within 12 months → 25% extra tax
• Filed within 24 months → 50% extra tax
• Filed within 36 months → 60% extra tax
• Filed within 48 months → 70% extra tax

So, even though you now have more time, it is better to file early to avoid paying higher penalties.
