Late Filing Penalty (5%) vs Late Payment Penalty (0.5%)
Filing Form 4868 protects you from the most severe IRS penalty:
IRS Penalty Rates Comparison:
- Failure to File Penalty (WITHOUT Form 4868): 5% of unpaid taxes per month (up to 25% max).
- Failure to Pay Penalty (WITH Form 4868): Only 0.5% of unpaid taxes per month (up to 25% max).
