About Course

CP2000 notices involving securities sales present a recurring practitioner fact pattern that turns on a single mechanical question: was the security’s cost basis ever reported to the IRS, and if not, how can the practitioner reconstruct and document a defensible figure. This self-study program gives Enrolled Agents and tax return preparers a narrow, practice-focused framework for exactly this fact pattern — the covered-versus-noncovered securities distinction under IRC §6045(g), a four-scenario method for reconstructing basis when a client’s own records are incomplete, a structured approach to choosing and documenting a CP2000 response position, and the Form 8949/Schedule D mechanics for entering the correction.

This course assumes working knowledge of the general CP2000/Automated Underreporter process and of the substantive §1014/§1015 basis rules for inherited and gifted property, both covered in depth elsewhere in this catalog, and does not re-teach either. It focuses specifically on the securities-basis-mismatch fact pattern: reading a securities-sale CP2000 notice, distinguishing genuine broker error from an expected noncovered-security reporting gap, sourcing evidence across four distinct scenarios (documented purchase, inherited security, gifted security, and total absence of records), and assembling a response — including the correct Form 8949 column (e)/(f)/(g) treatment for each fact pattern — that an IRS examiner can act on without a second round of correspondence.

What Will You Learn?

  • Distinguish covered securities from noncovered securities under IRC §6045(g) and identify the effective date that applies to a specific security type, including securities received through a corporate action
  • Read a securities-sale CP2000 notice and its transaction attachment to identify a Box B or Box E item and explain why a missing or unreconciled basis can produce a proposed tax on full gross proceeds
  • Classify a basis-reconstruction case into one of four evidence scenarios — documented acquisition, inherited security, gifted security, or total absence of evidence — and apply the correct documentation standard for each, including the consistent basis reporting requirement under §1014(f) where a Schedule A (Form 8971) applies
  • Determine the response deadline and extension procedure from the specific notice in hand, and select the correct response position — agreement, partial agreement, or disagreement — following the notice's own response form instructions
  • Build a transaction-level reconciliation for a partial-agreement response and identify the narrow circumstances that actually require filing Form 1040-X alongside a CP2000 response
  • Complete Form 8949 for both Box B/E sub-scenarios and for a Box A/D item with an incorrect reported basis, using the correct column (e)/(f)/(g) mechanics and the Worksheet for Basis Adjustments where applicable
  • Trace a corrected Form 8949 computation to the appropriate Schedule D line and assemble a complete, evidence-based CP2000 response package

Course Content

Module 1 — Why Basis Mismatches Trigger a CP2000 — Covered Securities and What the IRS Actually Sees
This module explains why missing or incorrect cost basis on a securities sale generates a CP2000 notice, covering the covered-versus-noncovered securities distinction under IRC §6045(g) and how corporate actions affect that status. You will learn to read a CP2000 notice's transaction attachment and correctly identify a Box B or Box E item. By the end of this module, you will be able to diagnose whether a flagged transaction reflects an expected noncovered-security reporting gap or a genuine broker error.

Module 2 — Reconstructing Cost Basis — A Four-Scenario Evidence Framework
This module presents a four-scenario framework for reconstructing cost basis when a client's records are incomplete: documented purchases, inherited securities, gifted securities, and cases with no records at all. You will learn the specific documentation standard and evidence-sourcing approach for each scenario, including the consistent basis reporting requirement under §1014(f). By the end of this module, you will be able to classify any basis-reconstruction case and gather the right evidence for it.

Module 3 — Analyzing the Notice and Choosing a Response Path — Agreement, Partial Agreement, or Disagreement
This module covers how to analyze a CP2000 notice and choose the correct response position — agreement, partial agreement, or disagreement — based on the notice's own instructions and deadline. You will learn to build a transaction-level reconciliation for partial-agreement cases and determine when Form 1040-X is actually required alongside a response. By the end of this module, you will be able to assemble a complete, well-documented response package for any response position.

Module 4 — Completing the Response — Form 8949 and Schedule D Correction Mechanics
This module completes the response package by covering the exact Form 8949 mechanics for correcting a flagged transaction, including the different treatment required for Box B/E and Box A/D items and the Worksheet for Basis Adjustments. You will work through a mixed covered/noncovered lot example and learn how corrected totals flow to the correct Schedule D line. By the end of this module, you will be able to complete a technically accurate Form 8949 correction and assemble the full CP2000 response package.
