CPA mobility lets a licensed accountant in good standing serve clients in other states without applying for a second license, paying a second fee, or notifying the host state’s board in advance. Every U.S. accountancy jurisdiction now recognizes it, so if your home-state license is active and you met the standard education, exam, and experience requirements when you got it, you can generally cross state lines the day a client asks. The catch is that mobility covers you as an individual practitioner. Your firm, your office locations, and your disciplinary exposure all follow different rules.
What Individual Mobility Actually Lets You Do
The model law behind mobility, the Uniform Accountancy Act, describes the individual privilege in three words: no notice, no fee, and no escape.1National Association of State Boards of Accountancy. Uniform Accountancy Act 8th Edition
- No notice. You don’t have to register with the host state’s board, submit an application, or wait for approval before you start working.
- No fee. The host state charges nothing for the privilege, and there’s no annual renewal on the host-state side.
- No escape. Practicing in the host state automatically subjects you to its laws, rules, and disciplinary authority, even though you never signed anything and don’t hold a local license.
Under Section 23 of the UAA, a CPA with a valid certificate from any jurisdiction has “all the practice privileges of licensees” in the host state, as long as the substantial equivalency requirements were met at the time of initial licensure. Those baseline requirements are 150 semester hours of college credit, passing the Uniform CPA Examination, and at least one year of supervised professional experience.2National Association of State Boards of Accountancy. Uniform Accountancy Act 9th Edition
As of 2026, all 55 accountancy board jurisdictions — the 50 states, the District of Columbia, and four U.S. territories — are recognized as substantially equivalent.3National Association of State Boards of Accountancy. Substantial Equivalency For nearly every currently licensed CPA, that means the equivalency question is already answered.
Physical Presence or Remote Work
Mobility applies whether you travel to the host state or deliver services electronically from your home office. Tax preparation, financial consulting, and advisory work provided remotely all sit inside the same framework. A CPA based in one state can serve clients nationwide through digital channels without any extra licensing step.
The situation gets more tangled when a CPA lives in one state, works remotely for a firm based in another, and serves clients in a third. States define “principal place of business” differently. Some look at where the CPA lives; others look at where the firm’s office sits. Checking the specific rules for every state where you’re performing services or setting up residency is worth the time, especially as boards pay closer attention to remote work arrangements.
The One Place Mobility Doesn’t Cover You
Mobility is not a substitute for holding a license where your work is based. If a state is your principal place of business, you need an actual license there. Mobility fills in for every other state you touch from that home base, not for the home base itself.
Your Firm May Still Need to Register
Individual mobility and firm registration are separate tracks. Even when every accountant in a firm personally qualifies for mobility, the firm itself can still owe the host state a permit. What triggers that permit is attest work.
Attest Services Are the Trigger
Attest services are engagements where the CPA expresses an opinion or provides assurance about financial information — audits, reviews, compilations, and agreed-upon procedures. Under UAA Section 7, a firm with an office in a state must hold a permit if it performs attest services or uses the title “CPA firm.”2National Association of State Boards of Accountancy. Uniform Accountancy Act 9th Edition
A firm with no office in the host state can perform attest services there without a permit, but only if it meets specific conditions: it complies with peer review requirements, the work is done through individuals who have practice privileges under Section 23, and the firm can lawfully provide those services in the state where the individual CPAs have their principal place of business.2National Association of State Boards of Accountancy. Uniform Accountancy Act 9th Edition Miss any one of those conditions and the firm has to register.
Non-Attest Work Sits Outside the Rule
Firms that only do non-attest work — tax preparation, consulting, advisory services — can operate under the “CPA firm” title in a host state without a permit, as long as the work is delivered through individuals with mobility privileges.2National Association of State Boards of Accountancy. Uniform Accountancy Act 9th Edition For most small and mid-size firms that don’t issue audit opinions or review reports across state lines, this is the exemption that keeps them out of a patchwork of state registrations.
A Physical Office Changes Everything
Opening a physical office in another state resets the analysis. Once a firm has a brick-and-mortar presence there and uses any CPA-related title, it must register with that state’s board regardless of whether it does attest work. Many states also require the firm to designate a resident manager for each in-state office who holds a CPA license in that state. Remote satellite offices and co-working arrangements should be evaluated carefully before they trip that trigger.
One boundary worth knowing: firms that audit public companies or broker-dealers also have to register with the Public Company Accounting Oversight Board.4Public Company Accounting Oversight Board. Registration That’s a federal requirement separate from any state firm permit and doesn’t substitute for one.
Peer Review Keeps the Firm Exemption Alive
Peer review is what lets a host state trust an out-of-state firm it has never directly supervised. Under the UAA, firms that issue attest or compilation reports must undergo a peer review at least once every three years as a condition of permit renewal.2National Association of State Boards of Accountancy. Uniform Accountancy Act 9th Edition The review is done by CPAs unaffiliated with the firm and examines whether the professionals supervising attest engagements and signing reports meet professional competency standards.
For firms practicing across state lines without a local office, peer review compliance is one of the specific conditions that exempts them from a host-state permit. If peer review lapses, that exemption drops away, and the firm would need to register in every state where it performs attest services. A “pass with deficiencies” or “fail” rating also flags the firm for additional host-state scrutiny.
You Consent to Host-State Discipline the Moment You Practice
The “no escape” piece of mobility is where the enforcement sits. By practicing in a host state, physically or remotely, you automatically consent to that board’s investigative and disciplinary authority. The board can pursue complaints, run investigations, and impose sanctions even though you don’t hold a license there.2National Association of State Boards of Accountancy. Uniform Accountancy Act 9th Edition The authority reaches both the individual CPA and the firm employing them.
Consequences range from administrative fines to suspension or revocation of the right to practice in that jurisdiction. Some states impose fines reaching into six figures for licensed firms in serious cases. Amounts vary, but enforcement around unlicensed attest work is consistently aggressive.
Discipline Follows You Home
Sanctions don’t stay local. Host boards report actions back to the practitioner’s home jurisdiction, and the information flows into CPAverify, NASBA’s national license verification tool. CPAverify draws directly from state boards and carries markers for enforcement actions, non-compliance, and disciplinary orders.5National Association of State Boards of Accountancy. All About CPAverify With 53 jurisdictions participating as of early 2026, a disciplinary record in one state is visible everywhere else. A single misconduct finding in a host state can prompt parallel investigations in your home state and any other state where you practice.
Keeping Your Mobility Active
Mobility depends on your home-state license staying active and in good standing. That means keeping up with continuing professional education. Most jurisdictions require around 40 hours of CPE annually, usually including an ethics component, though the exact rules come from your home state’s board. If your license lapses or drops to inactive status, your right to practice everywhere else drops with it.
Your home state’s CPE rules generally govern, even when you’re serving clients elsewhere. The no-escape principle still lets a host state’s board hold you to its own professional standards for work done within its borders, so the practical rule is to meet home-state requirements without slippage and to know that host states can still evaluate whether your competency matches the work you’re doing there.
