7.3 Professional Firms, Annual Reports & Board Registration

Key Takeaways

  • A dental practice organized as an entity operates under the Minnesota Professional Firms Act, MN Stat. §§ 319B.01 to 319B.12, and registers with the Board of Dentistry — the mechanism that reconciles entity practice with the corporate practice bar in MN Stat. § 150A.11, subd. 1.
  • MN Rules 3100.9100 requires the annual report to be submitted on Board forms and under oath, and to state the firm's name and registered office, every address at which the firm provides dental services, the name, address, and position title of each director, officer, and shareholder, and a certification as to the licensure status of each shareholder, director, officer, employee, and agent under MN Stat. § 319B.11, subd. 4(a).
  • MN Stat. § 150A.091, subd. 18 makes the firm's annual fee due by December 31 and authorizes a late fee established by the Board not to exceed $15 if the fee is not postmarked or otherwise received by that date.
  • MN Rules 3100.9300 requires the Board to revoke or refuse to renew the registration of any firm that no longer meets all requirements of the Minnesota Professional Firms Act, adjudicated under the Administrative Procedure Act, MN Stat. ch. 14, and OAH rules 1400.5100 to 1400.8401.
  • MN Rules 3100.9400 requires a firm intending to admit a new shareholder or member to notify the Board in its annual report of that person's identity, licensure status, and residence address; MN Rules 3100.9500 subjects firm names to MN Rules 3100.6400 and MN Stat. § 319B.05.

7.3 Professional Firms, Annual Reports & Board Registration

Section 7.1 established the corporate practice bar: no corporation may practice dentistry, furnish dental advice or dentists, or solicit dental patronage. Yet most Minnesota dental practices are organized as professional corporations, professional limited liability companies, or professional partnerships. The reconciliation lies in the second exception in MN Stat. § 150A.11, subd. 1 — the statute "does not prohibit dentists from incorporating their practice of dentistry for business purposes under the special provisions of a corporate practice act for dentistry."

That corporate practice act is the Minnesota Professional Firms Act, MN Stat. §§ 319B.01 to 319B.12, and the price of the exception is an ongoing registration and reporting relationship with the Board of Dentistry, governed by MN Rules 3100.9100 through 3100.9500.


1. The Annual Report — MN Rules 3100.9100

The rule prescribes both the form and the contents:

"Annual reports of professional firms organized under Minnesota Statutes, sections 319B.01 to 319B.12, inclusive, must be submitted upon forms furnished by the board and must require submission of the following information under oath:

A. name and registered office of the firm; B. address or addresses at which the firm is providing dental services; C. name and address of each director, officer, and shareholder, and the position title of each officer; and D. a certification as to the licensure status of each shareholder, director, officer, employee, and agent as required by Minnesota Statutes, section 319B.11, subdivision 4, paragraph (a)."

Three features deserve attention:

  • "Under oath." This is not a routine business filing. A false statement in the annual report is a sworn misstatement, and MN Rules 3100.6200, item H independently makes falsifying "other records with respect to licensure ... and the practice of dentistry" conduct unbecoming a licensee.
  • Item B distinguishes registered office from service locations. A firm with a registered office in one city and three clinics elsewhere must list all of them. This is how the Board maintains an accurate map of where regulated dentistry is actually delivered.
  • Item D is a licensure certification, and it sweeps broadly — shareholders, directors, officers, employees, and agents. The Professional Firms Act restricts who may own and govern a professional firm, and the Board's annual review is the enforcement point.

2. Board Review — MN Rules 3100.9200

"The board must review its licensure records and conduct any further investigation the board deems necessary and, if the board finds that the annual report does not conform to the requirements of the Minnesota Professional Firms Act and the rules adopted thereunder, the board shall inform the applicant of the necessary requirements for conformity."

The rule also builds in administrative efficiency: "The board may delegate the review and investigation of annual reports to the executive secretary so that annual reports will be acted upon in a timely manner in the intervals between meetings of the board. Any annual reports that are not approved by the executive secretary must be considered by the full board at the board's next meeting." Routine approvals move at staff speed; anything problematic goes to the full Board.


3. The Money and the Deadline — MN Stat. § 150A.091, Subdivision 18

"Any corporation or professional firm whose annual fee is not postmarked or otherwise received by the board by the due date of December 31 shall, in addition to the fee, submit a late fee as established by the board, not to exceed $15."

Two points to hold:

  1. December 31 is the firm deadline, and it is a calendar date — unlike individual licenses, which expire on the last day of the licensee's birth month in an even- or odd-numbered year matching the birth year (MN Rules 3100.1700, subp. 1a). A dentist therefore tracks two unrelated deadlines: a personal birth-month biennial renewal and a December 31 firm filing.
  2. The late fee is capped at $15 — a trivial sum next to the 25 percent late fee on a biennial license renewal (§ 150A.091, subd. 7). The consequence of neglecting the firm filing is not the fee; it is registration revocation under 3100.9300.

4. Revocation of Registration — MN Rules 3100.9300

"The board shall revoke or, if appropriate, refuse to renew the registration of any firm which no longer meets all the requirements of the Minnesota Professional Firms Act. The firm's eligibility to be registered or to continue registration must be adjudicated under the applicable provisions of the Administrative Procedure Act, Minnesota Statutes, chapter 14, and the rules of the Office of Administrative Hearings, parts 1400.5100 to 1400.8401."

The verb is shall, and the trigger is failing all the requirements — not merely a late filing. Note the procedural protection: firm registration is adjudicated as a contested case before the Office of Administrative Hearings, the same forum in which individual licensee discipline is heard. A firm facing revocation gets notice and a hearing.


5. New Shareholders or Members — MN Rules 3100.9400

"Whenever a professional firm intends to admit to the firm a new shareholder or member, the firm shall notify the board in the firm's annual report indicating the identity, licensure status, and residence address of each new shareholder or member."

The reporting vehicle is the annual report, not a separate filing, and the three data points are fixed: identity, licensure status, residence address. Because the Professional Firms Act limits ownership to qualified professionals, the licensure-status element is the substantive one — admitting an unlicensed shareholder is precisely the defect that triggers 3100.9300.


6. Firm Names — MN Rules 3100.9500

One sentence, and it routes back to material already covered: "The names of professional firms are governed by part 3100.6400 and Minnesota Statutes, section 319B.05."

So a firm name is tested exactly as a practice name is: it may not connote unusual or superior dental ability, and it may not be likely to create a false or unjustified expectation of favorable results. "Twin Cities Elite Dental Group, P.A." fails the first test as surely as a sole practitioner's shingle would.


7. Putting the Compliance Calendar Together

ObligationDeadlineAuthorityConsequence of missing it
Individual license renewalLast day of the licensee's birth month, in the even- or odd-numbered year matching the birth yearMN Rules 3100.1700, subps. 1a, 230 days to renew with a late fee of 25% of the biennial renewal fee; then administrative termination (not discipline)

Professional firm annual reportFiled on Board forms, under oath, annuallyMN Rules 3100.9100Nonconforming report → Board informs the firm of requirements (3100.9200); persistent failure to meet Act requirements → revocation or refusal to renew via contested case (3100.9300)
New shareholder or member noticeIn the annual reportMN Rules 3100.9400Unqualified owner → firm no longer meets the Act → 3100.9300
Address of recordWithin 30 days of any change of postal or email addressMN Stat. § 150A.09, subd. 3Independent violation; also causes missed notices

A scenario worth rehearsing. Dr. Olson practices through Olson Dental, P.A. She was born in June of an odd-numbered year, so her personal license renews at the end of June in odd years. Her firm's annual fee is due December 31 every year. In 2026 she admits an associate as a shareholder. Three separate obligations attach: renew her own license by June 30, 2027; pay the firm's annual fee by December 31, 2026 and again by December 31, 2027; and report the new shareholder's identity, licensure status, and residence address in the firm's annual report. Missing the June date costs her a 25 percent late fee and, after 30 days, her right to practice. Missing December 31 costs up to $15. Admitting a shareholder who turns out to be unlicensed costs the firm its registration.
