Anyone Can Legally Prepare Your Taxes: What the PTIN System Actually Verifies (and Doesn't)
A PTIN, the Preparer Tax Identification Number the IRS requires of anyone paid to prepare a federal tax return, is often assumed to work like a license. It does not. Obtaining one requires no competency exam and no continuing education for unenrolled preparers, which is why anyone can legally prepare a tax return for pay in the United States. In the most recent public IRS breakdown by preparer type, tax year 2017, unenrolled preparers filed 39,252,790 of 76,715,982 paid-preparer individual returns, more than CPAs and enrolled agents combined. The IRS itself names ghost preparers, who prepare a return but do not sign it, on its annual Dirty Dozen list of tax scams. For a legitimate CPA, EA, or credentialed firm, this is not background noise. It is the single highest-impact fact most prospective clients never check, and surfacing your own verification trail clearly is one of the most direct ways to win the trust a lightly regulated market otherwise makes hard to earn.
What a PTIN actually is, and what it is not
The IRS requires a Preparer Tax Identification Number, a PTIN, of anyone paid to prepare or assist in preparing a federal tax return. Roughly 685,000 US tax professionals hold one for 2026. What a PTIN does not do is confirm competency. Unlike the CPA license, which requires a rigorous exam, supervised experience, and ongoing continuing education under state board oversight, or Enrolled Agent status, which requires either passing a three-part IRS exam or prior IRS employment plus ongoing continuing education, a bare PTIN for an unenrolled preparer requires neither an exam nor continuing education.
The practical result is that "my preparer has a PTIN" and "my preparer is competent and accountable" are two different claims, and only credentialed status, CPA, EA, or in a handful of states a registered tax preparer designation, closes that gap. Consumer-finance guidance, including Forbes Advisor and TurboTax's own education content, consistently recommends checking a preparer against the IRS Directory of Federal Tax Return Preparers, the NASBA CPA Verify tool, or a state board before hiring, a distinctly higher-diligence step than most local-service categories prescribe, precisely because the baseline is so low.
The scale of the gap, and its limits
In the most recent year with a public IRS breakdown by preparer type, tax year 2017, of 76,715,982 individual returns filed by a paid preparer, 39,252,790 were prepared by unenrolled preparers, versus 22,837,596 by CPAs and 9,509,999 by enrolled agents, meaning unenrolled, non-credentialed preparers filed more returns than CPAs and EAs combined. That figure is established, it comes directly from the IRS's own Return Preparer Office, but it is dated: a fresher breakdown has not been located in this research, and the exact split should be treated as illustrative of a durable structural pattern rather than a live, current statistic.
The structural pattern itself, not the exact percentage, is the durable takeaway: a very large share of paid tax preparation in the United States is performed by people who hold no license, no exam requirement, and no mandatory continuing education. That is not, on its own, evidence of fraud. Most unenrolled preparers work honestly. But it is exactly the condition that makes credential verification meaningfully more important in this category than in one where a baseline license is required to practice at all.
The IRS names the risk directly: ghost preparers
The IRS does not treat this as a hypothetical. "Ghost preparers," who prepare a return for a fee but refuse to sign it or include their PTIN, are a recurring, named entry on the agency's annual Dirty Dozen list of tax scams, a red flag the IRS itself tells taxpayers to watch for. That an active federal warning exists at all, for a specific fraud pattern inside exactly this buying decision, is itself evidence of how much the credential-verification step matters and how rarely most buyers actually take it.
For a legitimate, credentialed firm, this is a real differentiator. A firm that visibly and consistently surfaces its license number, PTIN, state-board standing, and directory listing, on its site, its Google Business Profile, and third-party directories where a client might check, is doing the one thing the IRS's own guidance recommends and almost no competitor makes easy to find. In a market this loosely regulated, that visible proof is not paperwork. It is the trust signal doing the heaviest lifting.

Straight answers
Frequently asked questions
Is this legal or tax advice about which credential I need?
No. This article summarizes public IRS, NASBA, and consumer-finance guidance about preparer credentials for informational purposes. It is not tax or legal advice, and a specific credentialing question should go to your state board, the IRS, or your own counsel.
Does having a PTIN mean a preparer is safe to hire?
A PTIN confirms IRS registration, not competency. Unlike a CPA license or Enrolled Agent status, a bare PTIN requires no exam and no continuing education for unenrolled preparers. Checking the IRS Directory of Federal Tax Return Preparers, the NASBA CPA Verify tool, or your state board adds a verification step a PTIN alone does not provide.
Is the unenrolled-preparer statistic in this article current?
No, and this article says so directly. The 39.25 million versus 32.3 million split is the most recent public IRS breakdown by preparer type located in this research, tax year 2017. The structural pattern it shows is durable; the exact current-year figures would need a fresher IRS pull before being quoted as precise.
How should a credentialed firm actually use this information?
By making its own verification trail visible and consistent everywhere a prospective client might check it, its site, its Google Business Profile, third-party directories, and the state board or IRS preparer directory itself, rather than assuming a credential speaks for itself. That consistency is also what lets an AI system confidently resolve and cite the firm at all.
