Federal tax penalties: name the charge before calculating it
Distinguish filing, payment, accuracy, preparer, and interest rules before applying the correct base, period, cap, and defense.
The decision that earns the point
Classify the tax fact before calculating
A federal tax penalty depends on the specific filing, payment, understatement, or preparer rule, its statutory base, duration, cap, and any defense. Interest under §6601 is a separate charge from a penalty and should not be folded into the penalty calculation.
Exam use
REG can test failure-to-file and failure-to-pay penalties, accuracy-related penalties, preparer penalties, reasonable cause, statutory caps, coordination, and the distinction between penalty and interest.
Your scratch-paper plan
Solve it in three moves
- 1
Name the exact charge
Separate failure to file, failure to pay, accuracy-related penalty, preparer penalty, and interest.
26 USC §6651: Failure to file tax return or to pay tax - 2
Build the statutory base and time
Use the correct unpaid tax, underpayment, return, or other base and count months or fractions of months when the statute requires.
26 USC §6651: Failure to file tax return or to pay tax - 3
Apply defenses, caps, and coordination
Test reasonable cause, maximums, and overlapping-penalty rules before finalizing the amount.
26 USC §6664: Definitions and special rules
Worked problem
Work the facts before choosing the answer
A return is two months late, counting each month or fraction of a month under §6651(a)(1). The unpaid-tax base is $20,000, no reasonable-cause exception applies, and no failure-to-pay penalty overlaps either month.
CPAPass original exam illustration using stated assumptions
Show the work
The failure-to-file penalty is $20,000 multiplied by 5% multiplied by two months, and the 25% statutory maximum is not reached.
Rule source: 26 USC §6651: Failure to file tax return or to pay taxAnswer
The failure-to-file penalty is $2,000. Compute any §6601 interest separately rather than calling it part of the penalty.

The trap and the repair
Common trap
Using a memorized percentage without naming the charge can select the wrong base, period rule, cap, defense, or overlap adjustment.
Repair
Write charge, statute, base, periods, rate, cap, defense, and coordination as separate inputs before calculating.
Federal charge classifier
Name the charge before using a rate
The same unpaid tax can generate different charges with different bases, defenses, caps, and timing rules.
| Charge | Controlling input | Required check | Authority |
|---|---|---|---|
| Failure to file or pay | Unpaid tax and each month or fraction of a month | Reasonable cause, maximum, and overlap reduction | 26 USC §6651: Failure to file tax return or to pay tax |
| Accuracy-related penalty | Portion of an underpayment attributable to a listed ground | Applicable ground, rate, and §6664 exception | 26 USC §6662: Accuracy-related penalty on underpayments |
| Return-preparer understatement | Preparer conduct and the statutory understatement rule | Reasonable-basis, disclosure, willfulness, or reckless-conduct facts | 26 USC §6694: Understatement of taxpayer liability by tax return preparer |
| Interest | Unpaid tax and statutory interest period | Calculate separately from additions to tax and penalties | 26 USC §6601: Interest on underpayment, nonpayment, or extensions of time for payment of tax |
After a miss
Recalculate a penalty from the statute
- 1
Label every amount in the facts as tax, penalty, addition to tax, or interest before choosing a formula.
- 2
Rework the two-month example after adding an overlapping failure-to-pay penalty and apply the §6651 coordination rule.
- 3
Take one additional penalty scenario and write the statutory base, period, cap, and defense before multiplying.
