How to Correct Errors in Filed ITR — Revised Return & Rectification

Made a mistake in your tax return? Here’s how to revise it, when you can’t revise, and how to respond to a defective return notice.

Quick takeaways

You can file a revised return under Section 139(5) if you discover an error or omission before the end of the assessment year or before assessment, whichever is earlier.

A belated return can also be revised.

Once the time limit expires, you may apply for rectification under Section 154 for apparent mistakes.

Overview

When can you revise?

Any error or omission — wrong income, missed deduction, incorrect TDS — can be corrected.

Time limit: 31st December of the assessment year (extended in some years) or before completion of assessment.

There is no restriction on the number of revised returns, but only the latest one filed within the due date is valid.

Important facts

How to file a revised return

Use the same ITR form you originally filed (or the appropriate one if the nature of income changed).

Select ‘Revised’ under filing type and enter the acknowledgment number and date of the original return.

Check all pre‑filled data again, make corrections, and submit.

Key concepts

What if you miss the revision deadline?

01

You can file a rectification request under Section 154 if the mistake is apparent from records — like arithmetic errors, mismatch of TDS, etc.

02

This can be done online through the e‑filing portal.

03

For other mistakes, you may have to wait for a notice from the tax department and respond appropriately.

Key takeaways

Avoiding mistakes from the start

Double‑check pre‑filled data with your documents.

Reconcile TDS with Form 26AS and AIS.

File early — you’ll have time to revise if needed.
