Wrong self assessment tax details in Itr 1 by mistake

If you've filed your ITR 1 and accidentally entered incorrect self-assessment tax details like the BSR code or CIN number, don't worry. You can usually correct this by filing a revised return before your original return is processed by the tax department. If your return has already been processed, you'll need to file a rectification application with the Assessing Officer. It's advisable to act quickly to resolve any tax credit mismatches.
