What PEEC Finalized

The AICPA Professional Ethics Executive Committee approved revisions to the Tax Services interpretation of the Code of Professional Conduct in May 2026, and the finalized guidance was reported in July. The interpretation sits at ET section 1.295.160 and governs when a firm can provide tax services to an attest client without impairing independence.

What Actually Changed

The revised interpretation keeps a principles-based framework rather than adopting a single quantitative threshold, which is the outcome anyone who followed the exposure drafts was watching for.

Tax advisory and tax planning services for attest clients are now expressly covered, where the earlier interpretation did not address them specifically
The "more likely than not" threshold that appeared in earlier drafts was dropped in favor of professional judgment factors
A standalone factor addressing transactions that lack economic substance was removed, and those situations fall under the broader guidance on support in the tax law
The guidance walks through evaluating advocacy and self-review threats, the two that tax work raises most often

How a Member Applies It

The factors a member weighs include confidence that the tax position is supported by applicable authority, whether the position reflects established professional practice, the likelihood that a taxing authority reviews it, and how significant the matter is to the attest engagement. Independence is impaired only if threats cannot be eliminated or reduced to an acceptable level. The revised interpretation takes effect January 15, 2027, and early implementation is permitted, so the existing interpretation governs until then.

What This Means for AUD Candidates

Ethics, Professional Responsibilities, and General Principles is 15 to 25 percent of AUD, and independence is one of the most reliably tested pieces of it. Two things follow from the January 2027 effective date. Your review course material on tax services and independence is current for exams taken now, and the conceptual framework it teaches, which is identifying threats and then deciding whether safeguards reduce them to an acceptable level, is exactly what the revision preserves. Learn the self-review and advocacy threats cold, since those are the two the tax services interpretation is built around. Our AUD exam guide covers the ethics and independence area, and our REG exam guide covers professional responsibilities on the tax side.
