REG Ethics, Professional Responsibilities, and Tax Procedures
REG coverage of tax-practice ethics, licensing systems, IRS procedure, and civil liability.
This part covers the responsibility side of REG. Candidates need these chapters because many questions turn on what a practitioner may do, disclose, sign, defend, or challenge, not just on the underlying tax computation.
REG ethics and procedure questions often begin with a role question. A taxpayer, preparer, CPA, state board, IRS examiner, court, or third party may have different rights, duties, remedies, and limits.
