I want to be sure my Federal payment owed is scheduled.

You can create an account to view: 

• Your payoff amount, updated for the current calendar day 

• The balance for each tax year for which you owe 

• Up to 24 months of your payment history 

• Key information from your current tax year return as originally filed. 

 It may take up to 1 to 3 weeks for payments to appear in the payment history. Please refer to this link below.
