When resubmitting a return after it was initially rejected, you will be prompted for a credit/debit card number even if you already entered it during your first submission.
You will not be double-charged as long as:
If you do need to change the primary SSN or EIN due to an initial entry error, the logic in our billing process identifies it as an additional return and therefore charges again.
If this happens, the most efficient method for getting your return submitted is to allow the charge to process. Then, contact our support center to request a refund of the charge associated with the rejected return. You can locate TaxAct business hours here.
