The Short Answer
Enrolled Agents (EAs) are federally licensed tax specialists — the only credential granted directly by the IRS. They specialize exclusively in taxation and have unlimited authority to represent clients before the IRS in all 50 states.
CPAs (Certified Public Accountants) are state-licensed accountants whose expertise spans tax, auditing, financial reporting, and business advisory. Many CPAs also prepare taxes, but their scope is broader — and not all CPAs specialize in tax representation.

What Is an Enrolled Agent?
An Enrolled Agent is the highest credential the IRS grants to tax professionals. The designation is federal — not state — which means an EA licensed in Florida has the same authority before the IRS as one licensed in California or New York.
To become an EA, a tax professional must either pass the IRS Special Enrollment Examination (a rigorous 3-part test covering individual tax, business tax, and representation) or have prior IRS work experience. EAs must complete continuing education every three years and are subject to the IRS's ethical standards (Circular 230).
Because EAs specialize exclusively in taxation by definition, they typically have deeper tax expertise than a generalist CPA — particularly in areas like IRS audit representation, tax resolution, and multi-year back tax issues.
What Is a CPA?
A Certified Public Accountant is a state-licensed accounting professional who has passed the Uniform CPA Examination and met their state's experience and education requirements. CPAs have broad accounting authority — they're the only professionals who can conduct financial statement audits, which are required by banks, investors, and public companies.
Many CPAs also prepare taxes and can represent clients before the IRS. But not all CPAs specialize in tax — some focus on audit, corporate accounting, or financial advisory. A CPA who primarily does financial statement work may have less day-to-day IRS representation experience than a dedicated EA.
CPA licenses are also state-specific. A CPA licensed in Florida typically needs to apply for licensure in other states (or rely on reciprocity) to practice there. An EA's federal license works everywhere.
Which One Does Your Small Business Need?
Choose an Enrolled Agent if you need:
- Tax preparation and filing (business or personal)
- Year-round tax strategy and planning
- IRS audit representation
- Tax resolution — back taxes, payment plans, OIC
- Bookkeeping + tax in one place
- An affordable, tax-specialist alternative to a large CPA firm
- A professional who can work with you in any state
Choose a CPA if you need:
- Audited financial statements (for investors or lenders)
- Complex corporate accounting and reporting
- SEC compliance or public company reporting
- Business valuation services
- Forensic accounting
Note: For most small businesses, none of these are required — which is why an EA is often the better fit.
The Small Business Case for an Enrolled Agent
For the vast majority of small businesses — sole proprietors, LLCs, S-Corps, partnerships — the core needs are accurate books, sound tax strategy, accurate returns, and someone who can handle the IRS if a problem ever comes up. An Enrolled Agent covers all of this, often at a lower cost than a CPA firm, with deeper specialization in exactly the areas that matter most for small business owners.
At Simple Books Now, Luisa combines EA credentials with hands-on bookkeeping — so your books, your taxes, and your IRS standing are all managed by one person who knows your business inside and out.
Common Questions
An Enrolled Agent (EA) is a federally licensed tax specialist authorized by the IRS. A CPA is state-licensed and covers a broader range of accounting services including auditing, financial reporting, and business advisory — but not all CPAs specialize in tax. EAs specialize exclusively in tax by definition.
Yes. Enrolled Agents have unlimited practice rights before the IRS — they can represent any client in any IRS matter, in any state. This is the same federal authority held by CPAs and attorneys.
It depends on what you need. If your primary needs are tax strategy, tax preparation, and IRS representation, an Enrolled Agent is often the better fit — and typically more affordable. If you need audited financial statements for investors or lenders, you need a CPA.
Generally yes. EAs typically charge less than CPA firms for tax preparation and representation services, while holding equivalent federal authority before the IRS. The cost difference is especially significant for small businesses.
Yes — and this is a significant advantage. Some EAs (including Luisa at Simple Books Now) offer both bookkeeping and tax services, meaning your books and tax strategy are always in sync with no hand-offs between professionals.
