Section 1: 10–20%R2

Federal Tax Procedures, Penalties, and Statutes of Limitations

Exam insight

The statute-of-limitations rules and the penalty percentages are worth memorizing cold. The AICPA expects you to know that omitting more than 25% of gross income extends the period to 6 years and that fraud is unlimited. Choosing the right court after a 90-day letter is another recurring tested decision.

What AICPA wants you to know

  • 1State the general 3-year assessment statute and its 6-year and unlimited extensions
  • 2Distinguish the assessment statute from the 10-year collection statute
  • 3Compute the failure-to-file and failure-to-pay penalties and their interaction
  • 4Apply the accuracy-related (20%) and civil fraud (75%) penalties
  • 5Apply preparer penalties under §6694 and §6695
  • 6Trace the audit, appeals, and litigation path, including the 90-day letter and court choices

Exam tip

Study smarter: before you expand each card, cover the screen and try to recall what the concept means from its title alone. Retrieving it from memory builds the recall the exam actually tests, and it beats re-reading.
