How do you know if you owe additional taxes after filing your tax return on TurboTax?

[KellenW]

Hello, 

When filing your tax return the TurboTax program will let you know if you have taxes due or if you will be receiving a refund. If you wish to find out if you owe past taxes due. You can call the IRS toll-free telephone number: Individual taxpayers in the United States: 800-829-1040, Monday through Friday, 7 a.m. to 7 p.m. local time. 

To determine if a debt is owed, and whether an offset will occur, you can contact Treasury Offset Program Call Center at (800) 304-3107. Enter the required information and it will let you know if you have any existing debt on file.
