How to open a password-protected ITR-V PDF
Last updated November 7, 2026
The usual password pattern for ITR-V acknowledgements, and what to do when it doesn't work. All guides
The usual password
The ITR-V acknowledgement PDF from the income tax portal is normally locked with the taxpayer's PAN in lowercase followed by their date of birth as DDMMYYYY. For example, a PAN of ABCDE1234F and a date of birth of 05 March 1990 gives abcde1234f05031990.
For a company or firm the date is the date of incorporation or formation instead of a date of birth.
If it doesn't open
Check the case first: the PAN part is lowercase. Then check the date order and that there are no spaces.
Try a current PDF reader such as a recent browser or Adobe Acrobat. Older readers can reject newer encryption.
If the client changed or re-downloaded the file, ask them to download it again from the portal rather than forwarding a photo or screenshot.
How IntegralChase handles it
When a client uploads a locked PDF, IntegralChase tries the common patterns built from the client's details, and asks the client or the firm for the password only if none of them work. The password is used to open the file and is not saved. See the security page for how the unlocked copy is stored.
