Tax Professional Credentials: What Do They Actually Mean?
Tax professionals can have very different credentials. Some are professional credentials, some are state licenses, some are IRS qualifications, and some are simply identification requirements.
The 30-Second Answer
EA: federal tax credential; enrolled to practice before the IRS. CPA: state accounting license with a broad accounting scope. Attorney: law license. AFSP: voluntary IRS filing-season program. PTIN: paid-preparer identification requirement, not a professional tax credential.
Credential Is Only the First Lens
A credential can tell you something meaningful about a professional foundation. It cannot tell you how much of the person’s actual practice is tax, whether they routinely handle your type of work, or whether they communicate in a way that works for you.
Representation Rights Matter
Enrolled Agents, CPAs, and attorneys generally have unlimited representation rights before the IRS while eligible to practice. AFSP participants may have limited rights in qualifying circumstances. A PTIN alone does not create broad IRS representation authority.
Do Not Confuse a PTIN With Certification
A valid PTIN generally means the individual has met the IRS identification requirement applicable to paid federal return preparers. It does not mean the IRS has licensed, certified, endorsed, or determined that the preparer is competent for a particular tax matter.
The Better Question
Do not ask only, “What letters are after your name?” Also ask, “What do you actually do all day?” That second question often tells you far more about whether the professional is right for you.
