How do I change the banking information for IRS tax payments?
If you're referring to banking information for direct debit of a tax liability when you e-file your tax return, you can correct this in the TurboTax program. As you begin the FILE portion of the interview, you'll select to make your payment by direct debit. At that point, the program "may" have information that transferred into your return from your earlier return(s).
To make changes, simply select the field (bank name, routing number, account number) that you wish to change. Double-check your new entries for accuracy before e-filing your return.
