TNTAP allows for making payments at any time. You can manage your account profile, access all of your account information, read, send, and receive messages from the Department of Revenue and much more at any time.
Taxpayers are not required to make submit the payment on a return at the same time they submit the return in TNTAP. The process of filing a return is separate from the process of making a payment in TNTAP. There is a “Make a Payment” button that will be displayed on the confirmation page after submitting a return, and you have a choice of making an online payment or not making an online payment when you file a return.
