The late payment penalty applies to any portion of your federal tax that remains unpaid as of the due date, typically the tax filing date. The IRS imposes a failure-to-pay penalty of one half of one percent for each month or part of a month that the tax goes unpaid.
1 The late filing penalty is 5% of the additional taxes owed amount for every month (or fraction thereof) your return is late, up to a maximum of 25%. 2  If you file more than 60 days after the due date, the minimum penalty is $135 or 100% of your unpaid tax, whichever is smaller. If you file more than 60 days after the due date, the minimum penalty is $135 or 100% of your unpaid tax, whichever is smaller. 2  Tip: The late filing penalty can be 10 times higher than the late payment penalty.
