What tax-professional credentials mean

United States credentials

CPA (Certified Public Accountant) is licensed by the state board of accountancy in the state of practice. The Uniform CPA Examination is administered by the AICPA and NASBA; passing the exam plus state-specific experience and education requirements yields the licence. CPAs may practice in any area of accounting and tax; specialty depth varies by individual practice.

EA (Enrolled Agent) is licensed by the IRS under Treasury Department Circular 230. EAs must pass the three-part Special Enrollment Examination (SEE) covering individuals, businesses, and representation, or qualify via prior IRS service. EAs may represent any taxpayer before the IRS in any matter regardless of state.

Attorney admitted to a state bar with tax specialisation may practice in tax matters federal and state-side; attorney-client privilege under federal law is broader than CPA-client privilege under IRC §7525, particularly in controversy and criminal-tax contexts.

Annual Filing Season Program (AFSP) participants are unenrolled return preparers who have completed continuing-education requirements; AFSP-only preparers have limited practice rights before the IRS.

PTIN (Preparer Tax Identification Number) is required for any paid preparer of US federal returns. PTIN-only status confers no licensure or examination requirement.

United Kingdom credentials

ACA (Associate Chartered Accountant) under ICAEW. CIMA (Chartered Institute of Management Accountants). ACCA (Association of Chartered Certified Accountants). All three are global accounting credentials with strong UK origin and presence.

CTA (Chartered Tax-Adviser) under the Chartered Institute of Taxation (CIOT). The CTA exam covers personal, business, and indirect-tax modules; CTA is the senior UK tax credential. ATT (Association of Taxation Technicians) is the foundational UK tax credential, often held alongside ACA or ACCA.

Solicitor admitted under the Law Society of England and Wales (or Law Society of Scotland or Northern Ireland) with tax practice. Barrister at the Tax Bar.

HMRC AML registration is required for tax practitioners providing services to the public; AML supervisor is one of HMRC, ICAEW, ACCA, CIOT, or specified other professional bodies.

What credentials don't tell you

Credentialing confirms baseline competence and ethical accountability. It does not establish: (a) practice depth in your specific matter, (b) responsiveness to client communication, (c) capacity availability during your engagement window, (d) jurisdictional reach where multiple jurisdictions are involved, (e) software/portal capabilities, (f) fee structure compatibility with your engagement.

Credentials are necessary but not sufficient. Client reviews, scoping calls, and engagement-letter detail close the gap.

Cross-jurisdictional engagements

Expat or multi-jurisdictional engagements typically require either a single firm with practice depth in all relevant jurisdictions (Big-4 or large mid-tier networks fit this profile), or coordinated engagement across two firms with explicit handoff protocols. Single-jurisdiction practitioners taking on multi-jurisdiction work outside their bench depth is a frequent source of error in expat tax filings — particularly on Form 8938, Form 5471, FBAR, and treaty-position elections in US-citizen-abroad scenarios.
