United States · guideWho can legally do your taxes? The full US gate map
The short answer
Three different gates, three different questions. Anyone with a valid PTIN (Preparer Tax Identification Number) may legally prepare and sign a federal tax return for compensation — no CPA, attorney, or enrolled-agent credential is required. Representing a taxpayer before the IRS beyond that — a power of attorney, an audit, an appeal, a collections case — is restricted under Treasury Circular 230 to attorneys, CPAs, and IRS-enrolled agents. A middle tier, the voluntary Annual Filing Season Program (AFSP), gives a non-credentialed preparer narrow representation rights limited to the returns they personally prepared and signed, and only in front of frontline IRS personnel. Knowing which gate a given task sits behind is the whole question.
Key facts — verified dates on each
The answer in one sentence
PTIN to prepare and sign. Circular 230 (CPA, attorney, or enrolled agent) to represent. AFSP as a narrow, voluntary middle tier. Every other question about "who can do my taxes" — can a non-CPA file my return, does my accountant need a license, who signs when the IRS sends a notice — resolves to one of these three gates, and the gates do not require the same credential.
The confusion usually comes from treating "doing taxes" as one activity. It is legally two: preparing/filing a return, and standing in front of the IRS on a taxpayer's behalf. A person can be fully qualified for the first and have zero authority for the second — that is not a loophole, it is how the rules are written, and it is worth understanding before choosing who prepares a business's returns.
Gate 1 — PTIN: who may prepare and sign a return
Under Internal Revenue Code section 6109 and its regulations, anyone paid to prepare, or substantially help prepare, a federal tax return, refund claim, or other tax document must hold a Preparer Tax Identification Number, renewed annually and issued directly by the IRS. There is no CPA, attorney, or enrolled-agent prerequisite to obtain one — a PTIN has no exam and no state-license requirement attached to it.
This is the gate that governs the actual work of computing a return, whether it is a Form 1040, a Schedule C, a partnership Form 1065, or a corporate Form 1120 or 1120-S. A PTIN holder can prepare and sign as the paid preparer on any of these. What a PTIN does not confer is any right to represent the taxpayer before the IRS beyond the specific return that was prepared and signed — that is a separate gate, below.
- Who needs one: anyone compensated to prepare or substantially assist in preparing a federal tax return or refund claim
- Who is exempt: employees preparing their own employer's return, and unpaid volunteers
- What it does NOT grant: any representation rights before the IRS beyond the return prepared and signed
Gate 2 — Circular 230: who may represent a taxpayer before the IRS
Treasury Department Circular 230 (31 CFR Part 10) reserves unlimited representation rights before the IRS to three groups: attorneys, CPAs in good standing, and IRS-enrolled agents. Unlimited representation means the practitioner can act on a taxpayer's behalf on any tax matter — an examination, an appeal, a collections case, a power of attorney filed on Form 2848 — regardless of who prepared the original return.
A plain PTIN-only preparer, with no further credential, has no representation rights at all beyond the narrow AFSP tier described next. That means a bookkeeper, an offshore preparer, or any uncredentialed professional can legally prepare a return, but cannot sign a Form 2848, cannot correspond with the IRS as the taxpayer's agent, and cannot appear in an interview on the taxpayer's behalf.
The middle tier: Annual Filing Season Program (AFSP)
The IRS runs a voluntary Annual Filing Season Program for non-credentialed preparers: 18 hours of continuing education each year, including a 6-hour federal tax law refresher course with a test (15 hours for preparers exempt under a recognized prior credential), plus PTIN renewal and consent to Circular 230's duties and restrictions. Completing it earns an "AFSP – Record of Completion" and a listing in the IRS's public directory of preparers.
AFSP representation rights are real but narrow: an AFSP-certified preparer can represent a client only on a return that preparer personally prepared and signed, and only before IRS revenue agents, customer service representatives, and similar frontline personnel — not before IRS Appeals, not in Collections negotiations, and not on any matter unrelated to a return they signed. A plain PTIN with no AFSP completion confers none of this — a common point of confusion, since PTIN and AFSP get used interchangeably in casual conversation but are not the same thing.
Where the license question actually shows up
Because Gates 1 and 2 are so permissive on paper, the practical question a business usually needs answered is not "is this legal" but "where does a lender, investor, or the IRS itself expect to see a CPA regardless of what the law strictly requires." That is a market-expectations question layered on top of the legal one, covered in the companion guide on Form 1120 below — the short version is that corporate and multi-entity returns are legal for any PTIN holder to prepare, but the market for that work is dominated by CPA firms, and some lenders and investors ask for CPA involvement as a condition of the relationship even where the IRS does not.
The one place the legal gate is unambiguous and non-negotiable is representation on an open IRS matter — a notice beyond a routine math-error correction, an audit, an appeal, or anything requiring a signed Form 2848. That work sits behind Circular 230 regardless of market convention, and no amount of preparer experience substitutes for CPA, attorney, or enrolled-agent status there.

Questions on this
Do I need a CPA to file my business tax return?
No. Any preparer with a valid PTIN may legally prepare and sign a federal return — Form 1040, Schedule C, Form 1065, Form 1120, or 1120-S. A CPA license is not a legal prerequisite for preparation. It becomes relevant only for representation before the IRS (Gate 2) or where a lender, investor, or your own risk tolerance calls for CPA involvement as a matter of practice rather than law.
What is the difference between a PTIN and Circular 230 status?
A PTIN authorizes preparing and signing a return for pay — it is issued by the IRS with no exam and no CPA/EA/attorney requirement. Circular 230 status (CPA, attorney, or enrolled agent) authorizes representing a taxpayer before the IRS on any matter, including audits, appeals, and collections. A preparer can hold one without the other; most uncredentialed preparers hold only a PTIN.
What is the Annual Filing Season Program and do I need it?
AFSP is a voluntary continuing-education program for non-credentialed preparers. It is not required to prepare returns, but a preparer who completes it gains narrow representation rights limited to returns they personally prepared and signed, in front of frontline IRS staff only — a middle tier between a bare PTIN (no representation rights) and full Circular 230 status (unlimited representation).
Who can sign Form 2848 (Power of Attorney) on my behalf?
Only someone eligible to practice before the IRS under Circular 230 — an attorney, a CPA in good standing, or an IRS-enrolled agent. An AFSP-certified or plain PTIN-only preparer cannot sign Form 2848 to represent a taxpayer generally, though AFSP holders retain the narrow limited-representation rights described above for returns they personally signed.
Can an offshore or non-US preparer legally prepare my US return?
PTIN eligibility is not restricted to US residents or US-credentialed professionals — the PTIN gate governs preparation, not location or citizenship. What an offshore, non-CPA/EA/attorney preparer cannot do is sign Form 2848 or represent the business before the IRS on any notice, audit, or dispute; that piece routes to a US-licensed CPA, EA, or attorney regardless of who prepared the underlying computations.
If my preparer only has a PTIN, who handles it if the IRS sends a notice?
A plain PTIN, without AFSP, carries no representation rights. A CPA, enrolled agent, or attorney needs to sign Form 2848 and take over correspondence with the IRS. See the companion guide on IRS representation for how that handoff typically works in practice.
Does this gate structure apply the same way to every tax form?
The PTIN/Circular 230 split applies uniformly across federal tax forms — 1040, Schedule C, 1065, 1120, 1120-S, 941, 990, and amendments all fall under the same preparation-vs-representation distinction. What varies by form is market convention: some forms (like corporate returns) are prepared almost entirely by CPA firms in practice, even though the law does not require it. That practical layer is covered form-by-form in the companion guides linked below.
Which guide covers specifically who can prepare a corporation's Form 1120?
See the companion guide on who can file Form 1120 — it applies this same PTIN-to-prepare, Circular-230-to-represent structure specifically to corporate returns, including where market convention pushes that work toward CPA firms even though the law does not require it.
