Missing tax deadlines triggers statutory civil penalties. The Failure-to-File penalty is ten times more punitive than the Failure-to-Pay penalty:
Assessed at 5% of unpaid tax per month (capped at 25%). If more than 60 days late, the minimum penalty is $525 or 100% of unpaid tax, whichever is less.
Assessed at 0.5% of unpaid balance per month (capped at 25%). If both penalties apply, the 5% failure-to-file penalty is reduced by the 0.5% failure-to-pay penalty.
Taxpayers with a clean 3-year compliance history can request a 100% one-time waiver of FTF and FTP penalties by contacting the IRS directly at 1-800-829-1040.
