Prerequisites
- A licensed dentist who will own the entity, verified: active license, no disciplinary action, clear on OIG LEIE and SAM.gov — see Vet a friendly dentist
- Your state’s permitted entity form confirmed — see DSO laws by state and your state’s page
- A name that satisfies both corporate and dental board naming rules
- A registered agent in the state of incorporation
- Counsel engaged
The default rule: dentists only
In nearly every state, a dental PC’s shareholders must all be licensed dentists, and often its directors and officers too. A handful of states carve out limited minority ownership for other licensees — California, for example, lets physicians, hygienists, and registered dental assistants hold up to 49% in aggregate, provided they never outnumber the dentist shareholders1 — but the planning default is a single dentist owner holding 100%. The dental support organization (DSO) is never a shareholder, incorporator, director, or officer. See Who can own a dental practice.Steps
1
Clear the name with both authorities
Check availability with the secretary of state and compliance with the dental board’s naming rules. Most states require a designator — “P.C.”, “Professional Corporation”, “Dental Corporation” — and several regulate the practice name itself. Arkansas requires the corporate name to contain a shareholder’s name and routes fictitious names through board approval; Oklahoma requires dental trade names to be registered with the Board of Dentistry; Delaware requires advertising under a trade name to carry the proper name of a dentist-owner.2Reserve the name if the state permits it. If your DSO brand differs from the PC’s legal name — it usually does — file the DBA separately and confirm the board’s trade-name rules cover how it appears on signage and ads.
2
Obtain the dental board certificate or pre-approval, if required
Several states put the dental board in the filing path, before or immediately after the secretary of state:
- West Virginia — no corporation may practice dentistry or hold itself out as able to without a certificate of authorization from the Board of Dentistry, renewed annually by June 30 (W. Va. Code § 30-4-16(c), (e)).3
- Arkansas — every dental corporation must hold a certificate of registration from the Board of Dental Examiners before it may open, operate, or maintain an establishment; the certificate renews annually and is non-assignable (Ark. Code Ann. § 4-29-408).4
- New York — organizing a PC requires a certificate from the licensing authority that each proposed shareholder, director, and officer is authorized to practice (N.Y. Bus. Corp. Law § 1503).5
3
Appoint a registered agent
Required in the state of incorporation. If you’ll expand, consider a national vendor now — see Choose registered agents across states.
4
File articles of incorporation
Must include:
- A dental purpose clause limiting the corporation to the practice of dentistry and activities ancillary to it — not “any lawful purpose”
- A licensee ownership attestation stating all shareholders are licensed dentists
- Share structure, one class of common stock, a modest number of authorized shares
- Registered agent and registered office
- Incorporator (should be the dentist or counsel, never the DSO)
5
Hold the organizational meeting and adopt bylaws
By written consent is fine. Elect directors and officers — all licensed dentists where the state requires it — adopt bylaws, authorize share issuance, and authorize opening bank accounts and naming signers.File the consents in a minute book. These records are evidence the PC is a real, separately governed entity, which is exactly what a corporate practice of dentistry (CPOD) challenge attacks. See Maintain corporate formalities.
6
Issue the stock certificate with a restrictive legend
Issue shares to the dentist. The certificate must carry a restrictive legend referencing the stock transfer restriction agreement. Without the legend, a transferee could argue they took free of the restriction.Execute the transfer restriction agreement at or immediately after issuance. See Draft the stock transfer restriction.
7
Get the EIN
Free and same-day from the IRS at irs.gov. The responsible party is the dentist-owner. Do not pay a third-party service for this.Save the CP 575 confirmation letter. You will need it for banking and every payer enrollment, and the legal name on it must match what you use everywhere else.
8
Register with state tax and labor agencies
State income tax withholding and unemployment insurance registration, since the PC will employ the dentists and hygienists.
9
Raise the S-election question with your CPA
A PC taxed as a C-corporation that is a personal service corporation faces a flat 21% federal rate under IRC § 11(b), with no graduated brackets. Many elect S status. The Form 2553 deadline is tied to the tax year — missing it costs a year.
Verify it worked
- State-stamped articles of incorporation in hand
- Dental board certificate of authorization or registration issued, where the state requires one, with its renewal calendared
- Entity shows as active and in good standing on the secretary of state’s website
- Bylaws and organizational consents in the minute book
- Stock certificate issued, with restrictive legend
- CP 575 EIN letter received, with the legal name recorded exactly as printed
- State tax and employer registrations confirmed
Common failure modes
The legal name must match everywhere. The CP 575, the W-9, NPPES, the payer applications, and the bank account must all carry the identical legal name. Name mismatch is the leading cause of first-claim rejections, and resolving it means re-filing enrollment with every payer.
