Ethics and Responsibilities in Tax Practice

Exam Insight

Circular 230, the SSTS, and the preparer-position confidence thresholds are tested on nearly every REG form. The exam rewards candidates who can match a fact pattern to the exact standard — substantial authority, more likely than not, or reasonable basis — and who know when contingent fees and disclosure are allowed.
