Dear Taxpayer(s),
This email ID has been registered as a primary contact by more than the permitted number of users on the E-filing website of the Income Tax Department. Therefore, taxpayer personal email ID (other than the one presently registered) may be used to update their contact details on the e-Filing portal. Similarly, if the Mobile number registered with e-filing account is also more than the permitted number of users then the Mobile Number should also be updated with taxpayer personal mobile Number.
