Starting an accounting firm reads like a business decision. It begins as a licensing one. If you hold a CPA certificate, it authorizes you personally and it does not authorize the firm you are about to open. If you do not hold one, the same board triggers decide what your practice may call itself and which engagements it may accept.
State boards issue a separate firm permit or firm registration, the name on the door triggers it as readily as the work going on inside, and in at least one state the board filing has to land before your entity legally exists. Boards differ, so there is no single national rule to copy, and every rule named here is one state's answer rather than the country's.
Starting an Accounting Firm Begins With Two Approvals, Not One
The firm permit is a second license, held by the entity, and its triggers are written into state law. Minnesota names four, and a firm has to hold a permit if it is any one of them (Minnesota Statutes 326A.05, subdivision 1):
- a firm with an office in the state performing attest services
- a firm with an office in the state performing compilation services, to the extent section 326A.10, paragraph (k), requires it
- a firm with an office in the state that uses the title CPA or CPA firm
- a firm with no office in the state that performs certain attest services for a client headquartered there
Attest is the audit and review family, not tax preparation or bookkeeping. A compilation is separate again, a set of financial statements your firm's name goes on with no assurance behind it, and the audit, review and compilation comparison works through what each level commits a firm to. That is why a tax-only practice can be caught by the title trigger and never by the attest or compilation ones. The model act's five-service definition of attest sits with growth strategy, and that act's version of these permit triggers sits with buying a practice.
The compilation trigger has a solo route through it. No individual licensee may issue a report on a compilation of financial information through a business form that holds no permit, unless the report discloses the name of that business and the licensee signs the compilation report as a certified public accountant, meets the competency requirement in applicable standards, and undergoes a peer review no less frequently than once every three years (Minnesota Statutes 326A.10, paragraph (k)).
The third trigger is the one that does not depend on the work at all. In Minnesota the title alone is enough, so a practice that only prepares returns and keeps books, and never touches an audit, still needs the permit the moment its name says CPA.
Arizona routes it through the work as well as the name. Attest services or compilation services shall be provided only through a registered firm in good standing in the state, and a business organization must register once it meets three tests together: a simple majority of its ownership belongs to CPAs in good standing in any jurisdiction, it has an office in the state, and it either performs those services or uses the CPA designation in its firm name (Arizona Revised Statutes 32-731).
California states the partnership case as a flat prohibition: no persons shall engage in the practice of accountancy as a partnership unless the partnership is registered by the board (California Business and Professions Code 5072).
Can a Non-CPA Own the Firm? What the Board Actually Tests
In each of the states named here, yes, and only inside a fence. California allows nonlicensee owners and then bounds them: licensees in the aggregate must comprise a majority of owners, except that a firm with two owners may have one owner who is a nonlicensee, and licensees must hold more than half of the equity capital and possess majority voting rights (California Business and Professions Code 5079).
The same section attaches conditions that survive the closing. A nonlicensee owner must materially participate in the business of the firm or an entity the firm controls, and the ownership interest reverts to the firm when that participation stops. A CPA or public accountant must hold ultimate responsibility for each financial statement attest and compilation service engagement (California Business and Professions Code 5079).
Minnesota adds a filing to the same idea. A CPA firm there may include nonlicensee owners, and the firm must register all nonlicensee owners with the state board as set forth by rule (Minnesota Statutes 326A.05, subdivision 3).
Arizona measures the majority in direct and indirect financial interests and voting rights, and it puts a reporting duty on the drift: a registered firm must notify the board in writing within one month of any change in owners that drops it below that simple majority (Arizona Revised Statutes 32-731). The licensee-majority test that all three descend from is the model act's, and the market-level version of that ownership question sits with growth strategy.
The Entity Filing Can Run Through the Board First
A professional corporation and a professional limited liability company, PC and PLLC, are the entity forms states reserve for licensed practitioners, and some boards care which one you pick. North Carolina points its rule at the two general statutes that create them, G.S. 55B and 57D, and then puts the board filing ahead of the incorporation (21 NCAC 08K .0104).
Before any CPA professional corporation or professional limited liability company can offer to perform or perform any professional services in the state, it must register with the Board. For a domestic firm, the incorporators must do that prior to incorporation of the CPA firm (21 NCAC 08K .0104).
The filing list is short and specific. The incorporators prepare and file the articles of incorporation with the Board, along with supporting documents and the checks for fees payable to the Secretary of State, complete and file the Board's registration form, and pay an initial registration fee of fifty dollars ($50.00). The registration then renews annually (21 NCAC 08K .0104).
California treats the corporate form as its own registration rather than a byline on the firm permit. A Certificate of Registration must be issued if the board finds the applicant corporation has complied with the professional corporation sections of the Corporations Code, the accountancy corporation sections of the Accountancy Act, and the board's own rules on security for claims and share ownership (California Board of Accountancy Regulations, section 75.5).
Who may sit on that corporation is set separately, and the rule carries two exceptions rather than one. Except as the nonlicensee-owner section and California Corporations Code 13403 allow, each director, shareholder and officer of a California accountancy corporation must be a licensed person, or a person licensed to render the same professional services where they practice (California Business and Professions Code 5154).
The second exception is the one a solo founder needs. A professional corporation with only one shareholder need have only one director, who is that shareholder and who also serves as president and treasurer, and the corporation's other officers in that situation need not be licensed persons (California Corporations Code 13403).
The Firm Name Is a Board Question Before It Is a Branding One
California sets two rules and one exception. No person or firm may practice public accountancy under any name which is false or misleading, and no person or firm may practice public accountancy under any name other than the name under which they hold a valid permit to practice issued by the board (California Business and Professions Code 5060).
The exception carries a clock. A sole proprietor may practice under a name other than the one on the permit provided the name is registered by the board and is in good standing, and a registration issued under the board's fictitious name rule expires five years after the date of issuance unless it is renewed before it expires (California Board of Accountancy Regulations, section 67).
Arizona says the same thing in one line: a registrant may not use any firm name other than the firm name that is registered with the board (Arizona Revised Statutes 32-731).
That is why the name comes early rather than at the branding stage. The engagement letter, the letterhead, the bank account and the website all carry it, and in a state that registers names, the only version you can lawfully practice under is the one the board has on file.
Security for Client Claims Can Be a Registration Condition
In California, security for client claims is a condition of the corporate registration, not a judgment call, and insurance is only one of the two ways to provide it. An accountancy corporation must provide and maintain adequate security for claims against it by its clients arising out of the rendering of, or failure to render, professional services (California Board of Accountancy Regulations, section 75.8).
The insurance route sets the floors. Cover for each claim of at least $100,000 per licensee, with the required maximum for each claim capped at $1,000,000, and a minimum guaranteed for all claims during any one calendar year of at least $250,000 per licensee, with that required maximum capped at $3,000,000 (California Board of Accountancy Regulations, section 75.8).
The alternative is a written agreement of the shareholders that they will jointly and severally guarantee payment by the corporation of its liabilities to clients. Doing neither does not remove the exposure. Each shareholder is then deemed to have agreed to be jointly and severally liable for those claims anyway (California Board of Accountancy Regulations, section 75.8).
That is one state's rule bolted to one entity form, not a national requirement, and the practical case for buying cover before the first engagement letter starts earlier than any rule does. The claims record on engagements that went out without a letter sits with the wider firm-pressure picture.
Peer Review Enrollment Starts With the First Report, Not the First Year
Peer review is the practice-monitoring study of a firm's accounting and auditing work, carried out by a reviewer from outside the firm. It reads like a year-two problem, and it is not. The trigger is a report date.
When a member's firm performs services within the scope of the practice monitoring standards and issues reports purporting to be in accordance with AICPA professional standards, the firm should enroll in the program by the report date of the initial engagement (Questions and Answers About the AICPA Peer Review Program, February 2024).
The first review then lands sooner than the calendar suggests. A firm's due date for its initial peer review is ordinarily 18 months from the date it enrolled in the program, or should have enrolled, whichever date is earlier (Questions and Answers About the AICPA Peer Review Program).
What Pulls a New Firm Into Scope
What pulls a firm into scope is the definition of an accounting and auditing practice: all of a firm's engagements performed under the Statements on Auditing Standards, the Statements on Standards for Accounting and Review Services, the Statements on Standards for Attestation Engagements, Government Auditing Standards issued by the US Government Accountability Office, and engagements under the standards of the Public Company Accounting Oversight Board (Questions and Answers About the AICPA Peer Review Program).
A firm whose only engagements are preparations of financial statements under AR-C section 70 is not required to enroll for AICPA membership purposes, and the same answer warns that some state boards require exactly those firms to enroll as a licensing condition (Questions and Answers About the AICPA Peer Review Program). If a preparation service is the practice you are opening with, the launch decision behind it sits with client accounting services.
Where Your State Board Sets Its Own Clock
North Carolina writes the deadline into its own rules. A CPA or CPA firm shall register with the peer review program within 30 days of the issuance of the first report provided to a client, and a new firm has to furnish the program its selected financial statements, corresponding work papers and any additional documentation required within 18 months of that first report (21 NCAC 08M .0105).
The services that put a firm in scope there are audits, reviews of financial statements, compilations of financial statements, and any engagement performed in accordance with the Statements on Standards for Attestation Engagements. The rule also states plainly that firms shall not rearrange their structure or act in any manner with the intent to avoid enrollment (21 NCAC 08M .0105).
California hangs the same duty on renewal instead of on the first report. To renew its registration in an active status, or to convert to active status, a firm must have a peer review report of its accounting and auditing practice accepted by a board-recognized peer review program no less frequently than every three years (California Business and Professions Code 5076).
Which Steps Actually Have a Queue
Four of these steps carry a stated dependency or a published wait, and they are the ones that set your earliest honest open date.
| Step | Trigger or dependency | Stated timing |
|---|---|---|
| Board registration of a domestic PC or PLLC, North Carolina | The decision to incorporate | Filed prior to incorporation, so it gates the entity |
| Firm permit decision, Minnesota | A complete application | Granted or denied no later than 90 days after filing |
| Peer review registration, North Carolina | The first report issued to a client | Register within 30 days, furnish work papers within 18 months |
| IRS e-file application | The firm already being formed | Up to 45 days from submission for approval |

The federal side splits into fast and slow. An employer identification number comes back straight away, since the IRS issues the EIN immediately online once the application is approved (IRS, Apply for an Employer Identification Number Online). The electronic filing identification number does not. It can take up to 45 days from the date of submission for the IRS to approve an e-file application (IRS, Become an Authorized e-file Provider), and the suitability check and responsible official rules behind that application sit with the outsourcing setup.
The Minnesota window has a release valve. Where the board is not yet able to determine whether a permit should be granted or denied, it may issue a provisional permit, which expires 90 days after issuance or when the board decides, whichever comes first (Minnesota Statutes 326A.05, subdivision 2).
Working Backwards From the First Engagement Letter
Pick the date you intend to sign your first engagement letter and count backwards from it. The name has to be registrable and registered. The entity has to be the form your board accepts, filed in the order your board wants it. The firm permit has to be granted, or a provisional one issued. Security for client claims has to be in place if your entity form conditions the registration on it. The peer review clock starts with your first report in North Carolina and at your registration renewal in California, so it is the one item whose start date you read out of your own board's rule rather than off your own calendar.
Then put that plan to your own board before you act on it. Boards differ line by line, and the only version that binds you is theirs.
Everything after that is the business rather than the license. Winning the first clients is a separate build, and so is how you price the work and the system that will hold the job records.
Capacity becomes the ceiling once the work arrives. Accountably places trained offshore accountants and tax preparers inside US firms, and a firm can grade real work first through the Free 40-Hour Proof Pilot, a fixed block of its own files prepared on the firm's software and put through full review before a single client file is committed.
