UDIN updation on IT portal

Current Status of UDIN Updation

As of 2026, the Income Tax e-filing portal allows for the post-facto updating of UDINs for certain forms, though the process has evolved since the 2021-22 period referenced in the forum post.

• Standard Procedure: Generally, when filing audit reports (such as Form 3CA/3CB-3CD), the portal requires the UDIN to be generated and updated within a specific timeframe (usually within 15 days of the form's submission).

• Late Updates: If the UDIN was not updated at the time of filing, the Income Tax portal often provides a "View/Update UDIN" functionality under the "e-File" > "Income Tax Forms" section. This allows professionals to link the valid UDIN to the submitted form.

• Verification: It is essential to ensure that the UDIN generated on the ICAI portal is "Active" and matches the details (PAN, Form Type, Assessment Year) of the document submitted on the Income Tax portal.

Recommended Steps

1. Log in to the Income Tax e-Filing Portal: Navigate to the dashboard.

2. Access Forms: Go to the "e-File" tab, select "Income Tax Forms," and then "View/Update UDIN."

3. Search for the Form: Locate the specific form filed for AY 2021-22.

4. Update: If the option is available, enter the correct UDIN. If the system does not allow an update for a form from a past assessment year, you may need to file a grievance through the portal or consult the ICAI's guidance on retrospective UDIN updation.
