Publication 5125 Publication 5125, the LB&I Examination Process PDF outlines the LB&I Examination Process (LEP) which provides an issue-based approach for conducting professional examinations from the first contact with the taxpayer through the final stages of issue resolution. LEP establishes roles and responsibilities for both LB&I examiners and taxpayers and sets specific expectations with respect to claims for refund. However, not all examinations are the same in scope, size, and complexity; therefore, portions of the publication may be more applicable to some cases than others. Publication 5125 highlights key factors in each phase of the examination including Planning, Execution and Resolution. IRM 4.46.1 provides general information and key definitions for LEP. IRM 4.46, sections 3, 4 and 5 provide the LEP planning, execution, and resolution procedures.
