I am facing a technical issue regarding the bank account addition on the Income Tax e-filing portal, which prevents me from filing tax returns as the registered Legal Heir for my late mother.

My mother passed away in June 2025. I am registered and approved as her Legal Heir on the e-filing portal.

While attempting to file her ITR for the current assessment year, I noticed that my bank account is listed under the "Failed Bank Accounts" section. This account of mine was used last year to file her ITR and received the refund in this account. And this bank account is very much active.

Furthermore, when logged in as the Legal Heir, the ITR portal does not provide an option to add or update a new bank account belonging to me.

I am completely locked out of updating the bank details myself and thus filing the return for my deceased mother.

No resolution received from the ITR customer care / grievance portal.

Any help/suggestions would be of great help. Thanks.
