About Course

This course is a practice-focused, four-module program on the federal statutes of limitation that govern when the IRS may assess additional tax, when a taxpayer may claim a refund, and how those two deadlines interact with the separate, already-running collection period once a tax has been assessed. It goes beyond a general overview of these deadlines to build the practical skills a preparer needs at the desk: calculating the general three-year assessment period and identifying when the six-year substantial-omission period or an unlimited assessment period actually applies, recognizing the narrow, statutorily defined circumstances that suspend the assessment period, computing the refund claim deadline and its look-back limitation on the amount recoverable, and correctly distinguishing all of this from the ten-year collection period that begins only after a valid assessment.

This course assumes general familiarity with individual and business federal income tax preparation and IRS administrative procedure. Course content is grounded in IRC Sections 6501, 6503, 6511, and 6502, and current Treasury regulations under those sections. This course is explicitly limited to the assessment and refund-claim statutes of limitation and their own suspension rules; the ten-year collection statute of limitations and collection resolution strategy are covered in depth in this catalog’s separate Collection Statute Expiration Date (CSED) Strategy course. Where this course’s own content touches the collection period, it does so only for comparison and to show how the assessment, refund, and collection deadlines interact in a single case.

What Will You Learn?

  • Calculate the general three-year assessment period under Section 6501(a), determine the correct filing date that starts the period under Section 6501(b)(1), and apply the six-year assessment period under Section 6501(e) when a taxpayer omits from gross income an amount exceeding 25 percent of the gross income stated on the return or, separately, omits more than $5,000 attributable to a specified foreign financial asset within the meaning of Section 6038D, applied without regard to that section's own dollar threshold and reporting exceptions, and distinguish this fixed six-year period from the open-ended extension under Section 6501(c)(8) for unfurnished required foreign-information reporting.
  • Identify the narrow circumstances in which the assessment period is unlimited under Section 6501(c) for a false or fraudulent return, a willful attempt to evade tax, or a failure to file a return, and correctly apply the designated-summons suspension under Section 6503(j), including its statutory definition, its judicial-enforcement 120-day rule, and its 60-day minimum-period guarantee.
  • Calculate the refund claim deadline under Section 6511(a) and apply the look-back limitation on the recoverable amount under Section 6511(b)(2), and identify the extended refund periods that apply to bad debts and worthless securities, net operating loss carrybacks, and foreign tax credits under Section 6511(d).
  • Distinguish the assessment and refund-claim statutes of limitation from the separate ten-year collection period under Section 6502, correctly classify collection-side suspension events — including a taxpayer's absence from the United States under Section 6503(c) and a pending innocent-spouse petition under Section 6015(e) — as suspensions of collection rather than assessment, and apply Form 872 consent extensions and statute verification procedures in client representation consistent with Circular 230 standards.

Course Content

Module 1 — The Assessment Statute of Limitations Under Section 6501
This module works through the general three-year assessment period under Section 6501(a), the deemed-filing rule under Section 6501(b)(1) that determines when the clock actually starts, and how a taxpayer can extend that period by signing a Form 872 or Form 872-A consent. You will also learn the six-year period for a substantial omission of gross income under Section 6501(e), including the separate $5,000 trigger for an unreported specified foreign financial asset — which applies without regard to Section 6038D's own dollar threshold — and the distinct, open-ended extension under Section 6501(c)(8) for unfurnished required foreign-information reporting.

Module 2 — Exceptions That Suspend or Eliminate the Assessment Period
Building on Module 1's general rule, this module covers the circumstances that either eliminate the assessment period entirely or merely suspend it for a defined period. You will learn the unlimited period under Section 6501(c) for a false or fraudulent return, a willful attempt to evade tax, or a failure to file; the suspension triggered by a notice of deficiency and a Tax Court petition under Section 6503(a)(1); the designated-summons suspension under Section 6503(j), including its 120-day judicial-enforcement rule and 60-day minimum guarantee; and the bankruptcy suspension under Section 6503(h), which applies different tail periods to assessment and collection.

Module 3 — The Refund Claim Statute of Limitations Under Section 6511
This module turns to the taxpayer's own deadline for claiming a refund under Section 6511. You will learn the general three-year-from-filing or two-year-from-payment test under Section 6511(a), the look-back limitation on the amount actually recoverable under Section 6511(b)(2), and the extended refund periods under Section 6511(d) for bad debts and worthless securities, net operating loss and capital loss carrybacks, and foreign tax credits — along with what a valid claim must contain and the informal claim and protective claim doctrines.

Module 4 — Practitioner Application: Reconciling Assessment, Refund, and Collection Deadlines
The final module reconciles everything covered in Modules 1 through 3 with the separate ten-year collection period under Section 6502, which begins only after a valid assessment. You will learn the collection-only suspensions under Section 6503(c) for a taxpayer's absence from the United States and Section 6015(e)(2) for a pending innocent-spouse petition, why neither affects the assessment period, and how to verify every date in a client's file against its own underlying document rather than the IRS account transcript alone, consistent with Circular 230 due-diligence standards.
