How the Penalty is Calculated
The IRS charges 5% of your unpaid taxes for each month (or partial month) that your return is late. The penalty starts the day after the filing deadline and continues until you file or until it reaches the maximum.
- 1Base Rate: 5% of unpaid taxes per month or partial month
- 2Maximum: 25% of unpaid taxes (5 months)
- 3Minimum: $530 or 100% of tax owed (if 60+ days late)
- 4Combined Rule: FTF reduced by FTP when both apply
