Three types of professionals are federally authorized to give tax advice and represent you before the IRS: enrolled agents (EAs), certified public accountants (CPAs), and tax attorneys. All three are regulated by the Treasury Department under Circular 230, which sets ethical and competency standards for anyone practicing before the IRS.1eCFR. 31 CFR Part 10 — Practice Before the Internal Revenue Service Unenrolled preparers can fill out returns and handle narrow interactions with the IRS, but their authority ends well short of what a credentialed professional can do. The right choice depends on what you actually need: a return prepared, an audit defended, or a case argued in court.
Enrolled Agents
Enrolled agents are tax specialists licensed directly by the IRS. Candidates pass a three-part exam covering individual taxes, business taxes, and representation procedures, and clear a suitability check that reviews tax compliance and criminal history.2Internal Revenue Service. Become an Enrolled Agent The credential is federal, so it works in every state without additional licensing.
EAs hold unlimited representation rights. They can speak for you in audits, appeals, and collection disputes at every administrative level of the IRS, and you don’t have to be present.3Internal Revenue Service. Understanding Tax Return Preparer Credentials and Qualifications To keep the credential, they complete 72 hours of continuing education every three years, with at least 16 hours each year and 2 of those in ethics.4Internal Revenue Service. FAQs: Enrolled Agent Continuing Education Requirements For everyday individual and small-business tax work, an EA is often the most cost-effective credentialed choice.
Certified Public Accountants
CPAs are licensed by state boards of accountancy, not the federal government. Licensure typically requires 150 semester hours of education, the Uniform CPA Examination, supervised work experience, and an ethics component.5NASBA National Association of State Boards of Accountancy. What Is the Uniform CPA Examination? Exact thresholds vary by state, and there is no national CPA license.
Like enrolled agents, CPAs have unlimited IRS representation rights for audits, appeals, and collections.3Internal Revenue Service. Understanding Tax Return Preparer Credentials and Qualifications Their broader accounting training suits situations that mix tax planning with financial reporting, business valuation, or bookkeeping. Continuing education requirements vary by state; the AICPA standard for its own members is 120 hours every three years.6AICPA & CIMA. CPE Requirements and Credits
Tax Attorneys
Tax attorneys do something the other two cannot: litigate. When a dispute leaves IRS administrative proceedings and enters the U.S. Tax Court or federal district court, an attorney admitted to that court’s bar can argue your case under formal rules of evidence and procedure.7United States Tax Court. Guidance for Petitioners: Starting a Case Non-attorneys can gain admission to Tax Court by passing a written exam the court gives at least every two years, but existing state-bar members face a simpler application.8United States Tax Court. Rule 200 – Admission to Practice and Periodic Registration Fee
Attorneys also handle criminal tax matters. Tax evasion under federal law is a felony carrying up to five years in prison and fines up to $100,000 for individuals or $500,000 for corporations.9Office of the Law Revision Counsel. 26 USC 7201 – Attempt to Evade or Defeat Tax If you are facing a criminal investigation, you need an attorney. No other professional can defend you in a criminal proceeding.
Confidentiality
Attorney-client privilege is the strongest confidentiality shield in tax matters. It protects your communications with your attorney even during criminal proceedings and litigation. EAs and CPAs have a narrower federal privilege that applies only in noncriminal tax matters before the IRS or in noncriminal federal court proceedings, and it does not cover written communications about tax shelters.10Office of the Law Revision Counsel. 26 USC 7525 – Confidentiality Privileges Relating to Taxpayer Communications If an ordinary audit could escalate into a fraud referral, conversations you had with a CPA or EA about the disputed items could be compelled as evidence.
Unenrolled Preparers
Anyone who prepares federal tax returns for pay must obtain a Preparer Tax Identification Number (PTIN), regardless of credentials.11eCFR. 26 CFR 1.6109-2 – Tax Return Preparers Furnishing Identifying Numbers The PTIN costs $18.75 and renews annually.12Internal Revenue Service. IRS Reminds Tax Pros to Renew PTINs for the 2026 Tax Season A PTIN by itself grants no representation authority. Preparers without an EA, CPA, or attorney credential can represent only clients whose returns they personally prepared and signed, and only before revenue agents, customer service representatives, and the Taxpayer Advocate Service.3Internal Revenue Service. Understanding Tax Return Preparer Credentials and Qualifications The moment the IRS moves your case to appeals or collections, an unenrolled preparer is locked out.
The IRS runs a voluntary Annual Filing Season Program for unenrolled preparers who want to show a higher baseline. Participants complete 15 to 18 hours of continuing education, depending on prior credentials, and earn a Record of Completion.13Internal Revenue Service. Annual Filing Season Program It doesn’t expand their representation rights, but it signals that they met a training standard.
Software and Free Programs
Commercial tax software walks you through a Q&A that builds your return. Some products guarantee they’ll cover IRS penalties and interest caused by calculation errors in the software itself.14Internal Revenue Service. E-file: Do Your Taxes for Free That guarantee is narrower than most users assume: it covers the software’s math, not your data entry or answer choices. Using software creates no practitioner relationship, and the IRS has held taxpayers liable for accuracy-related penalties even when errors originated in the software process.15Internal Revenue Service Taxpayer Advocate Service. 2013 Annual Report to Congress – Accuracy-Related Penalty Under IRC 6662(b)(1) and (2)
If your income is $69,000 or less, the IRS Volunteer Income Tax Assistance (VITA) program offers free return preparation at sites staffed by IRS-certified volunteers. Taxpayers 60 and older can use Tax Counseling for the Elderly (TCE), which focuses on pension and retirement questions.16Internal Revenue Service. Free Tax Return Preparation for Qualifying Taxpayers Neither offers ongoing representation, but for basic returns they are a legitimate free option.
Advice from friends, family, or social media carries no legal weight. These sources aren’t bound by Circular 230, can’t represent you, and their mistakes become yours. Following bad informal advice does not create a reasonable-cause defense against IRS penalties.
Which Professional You Actually Need
Most people who overpay for tax help do it by hiring above their situation. Match the professional to the problem:
- Straightforward W-2 return with standard deductions: an AFSP-completed preparer or commercial software is enough. A credentialed professional is overkill for a 30-minute return.
- Small business income, rental properties, or multistate filing: an EA or CPA. Both can prepare the return and represent you if the IRS questions it later.
- Business structuring, estate planning, or merger-related tax questions: a tax-focused CPA or a tax attorney. CPAs fit the ongoing financial reporting side; attorneys fit situations where legal structures and contracts drive the tax outcome.
- IRS audit or collection dispute: any unlimited-rights practitioner (EA, CPA, or attorney). EAs who specialize in representation are usually the most affordable for routine audits.
- Tax Court litigation or a criminal investigation: an attorney. No one else can appear for you in court or offer the full protection of attorney-client privilege in a criminal matter.
The common mistake is hiring a tax attorney for a routine return. Attorneys bill significantly more per hour, and their training centers on legal interpretation and litigation rather than return preparation. If no one is suing you and no one is threatening criminal charges, an EA or CPA will serve you better for less.
One boundary worth stating: you remain responsible for the accuracy of your return no matter who prepared it, and the IRS can assess negligence penalties against you regardless of the preparer’s role.17Internal Revenue Service. 20.1.5 Return Related Penalties Hiring a professional shifts expertise onto your side; it does not shift the return off your name.
How to Verify Credentials Before You Hire
Before handing over your Social Security number and financial records, confirm the person is who they say they are. The IRS keeps a free, searchable directory of federal tax return preparers who hold recognized credentials or an AFSP Record of Completion, updated regularly.18IRS.gov – Treasury. Directory of Federal Tax Return Preparers with Credentials and Select Qualifications
For CPAs, NASBA runs CPAverify.org, the only free national database of licensed CPAs and accounting firms, pulling data directly from state boards and including disciplinary markers.19NASBA. CPAverify: What Is It and How Can It Help For attorneys, each state bar publishes its own directory where you can confirm active licensure and standing. If someone calls themselves a tax attorney and doesn’t appear in their state bar’s records, walk away.
If a preparer’s work does turn out to be fraudulent, file Form 14157 (Complaint: Tax Return Preparer) with the IRS. If the misconduct affected a return that already generated an IRS notice, you’ll also need Form 14157-A, the Tax Return Preparer Fraud or Misconduct Affidavit.20Internal Revenue Service.
