Nearly every tax controversy turns on a date. This session surveys the limitations periods that govern federal tax practice—how long the IRS has to assess, how long it has to collect, how long a taxpayer has to claim a refund, and how long the government has to recover a refund it never should have paid—along with the many provisions that extend, suspend, or eliminate those periods entirely. Attendees will work through the relationships among these periods, the circumstances that leave a period open indefinitely, and the judicial filing deadlines that follow an IRS determination. The session also addresses recent developments regarding whether missed court deadlines can be excused, and touches on state limitations periods that diverge from the federal rules.
Agenda
  • Identify the general assessment period and the circumstances that extend or eliminate it
  • Explain how the collection period is calculated and the events that suspend it
  • Determine whether a refund claim is timely, and how long the government has to recover a refund paid in error
  • Recognize the judicial filing deadlines that follow IRS determinations and the consequences of missing them
  • Compare selected state limitations periods with their federal counterparts
