What to check before you answer
Is this letter really from the IRS?
The IRS writes first by mail. A real letter shows a notice or letter number, your name and part of your tax ID number. The IRS does not ask for payment by gift card, crypto or wire transfer. If in doubt, sign in to your IRS online account, where many notices are listed.
Common questions
Will I be penalized if I can't pay the full installment amount by the due date?
Yes. You may be penalized for failure to pay and the full amount of your net tax liability may become due immediately.
Can I choose how to apply an overpayment if I pay more than the installment amount?
No. We’ll apply it to the remaining net tax liability until it is paid in full. We can only refund or apply credit-elect payments or credits exceeding the full income tax liability.
What should I do if I disagree with the notice?
Call the toll-free number listed on your notice to review your account with a representative. Have your account information available when you call.
