PLLC is a limited liability company chartered to practice a licensed profession, and in late 2024 the question of whether to use one is no longer a state-by-state novelty. It is a patchwork with a federal overlay that most licensed trades now share.

Ten years into the form's broad adoption, the map is legible. Some states require the PLLC. Some forbid it. One large state is forcing professional corporations only. And every entity in this category, regardless of the state wrapper, now owes a beneficial-ownership report to FinCEN.

Who mandates what, and who won't let you

California is the outlier that matters. The Moscone-Knox Professional Corporation Act at Cal. Corp. Code §§13400 to 13410 recognizes a professional corporation as the vehicle for licensed practice, and the California Revised Uniform Limited Liability Company Act expressly carves out "a business that a person is licensed or authorized to engage in under the Business and Professions Code," forcing licensed professionals in regulated fields to form a PC rather than a PLLC or an ordinary LLC. There is no PLLC in California. Physicians, lawyers, architects, and accountants practicing in California go through the professional corporation chapter, file a DE-1 with the applicable licensing board, and accept the S-corp-flavored tax consequences that follow. If a client tells you their California therapy practice is a PLLC, they are either operating out of a different state or operating out of compliance.

New York sits at the opposite pole. Section 1203 of the New York Limited Liability Company Law provides that a professional service limited liability company may be formed only by licensed persons and requires a Certificate of Authority from the relevant licensing authority before the articles of organization may be filed with the Department of State. Every member has to be licensed in the profession. The PLLC is not a workaround; it is the required form for a professional practice that wants LLC treatment in New York.

Texas reached the same result through Chapter 304 of the Business Organizations Code, which requires a professional limited liability company for several enumerated trades including certified public accountants, architects, and licensed engineers. Tex. Bus. Orgs. Code § 304.001 pulls in the professional-entity subchapters, and § 301.003 limits ownership to licensed persons in the profession. The PLLC is available, not optional, for these trades.

Florida is the accommodating middle. Chapter 621 of the Florida Statutes permits a professional limited liability company for most licensed professions, and a licensed dentist or architect in Florida can elect either the PLLC under Chapter 621 or an ordinary LLC under Chapter 605 with appropriate disclosures, depending on what the practice board requires. The election rarely changes the tax picture, but it changes the name registration, the dissolution mechanics on death or license revocation of a member, and the professional-liability carve-outs inside the statute.

The takeaway for the advisor building a practice across state lines: the PLLC question is answered first by the licensing board, second by the state corporations code, and only third by anything tax-adjacent.

Federal tax parity, which is the point

Whatever wrapper the state requires, the PLLC runs through the same federal classification machinery as any other LLC. Treasury Regulation § 301.7701-3 is the check-the-box rule. A domestic eligible entity with two or more members defaults to a partnership; a single-member eligible entity defaults to a disregarded entity. Either can elect corporate treatment on Form 8832, and a corporation can then elect S-corp treatment on Form 2553. The regulation does not care whether the underlying state charter is an LLC, a PLLC, or a professional corporation, provided the entity is otherwise eligible. A California professional corporation, notably, does not have this flexibility; it begins life as a corporation and must elect S status affirmatively.

That parity is why the PLLC is attractive where it is available. A solo dermatologist in Austin who forms a single-member PLLC gets the liability shield permitted under Texas law, reports on Schedule C by default, and can elect S-corp treatment in year two when revenue justifies the payroll burden. The same practitioner in Los Angeles forms a medical corporation, is a corporation for federal purposes from day one, and has to run the S-election workflow out of the gate or sit in C-corp territory at 21%.

The §199A fence is still at $191,950 and $383,900

The Section 199A deduction survived the 2017 Act's sunset calendar into 2024, and it still punishes specified service trades or businesses above an income threshold. Revenue Procedure 2023-34 set the 2024 threshold amounts at $191,950 of taxable income for single filers and $383,900 for joint filers, with the full phase-out reached at $241,950 and $483,900 respectively. Above the ceiling, the SSTB classification under IRC § 199A(d)(2) zeroes the deduction for health, law, accounting, actuarial science, performing arts, consulting, athletics, financial services, brokerage services, and any trade where the principal asset is the reputation or skill of its employees or owners. Most of the trades that are required by state law to form as a PLLC live inside that fence.

Treasury Regulation § 1.199A-5(c)(2) is the anti-crack-and-pack rule. It blocks the maneuver where a law firm spins off its administrative functions into a sibling entity owned by the same partners in the hope that the admin entity, stripped of legal work, qualifies for the full 20% pass-through deduction. The regulation aggregates any trade that provides 80% or more of its property or services to an SSTB with 50% or more common ownership, treating the whole arrangement as part of the SSTB. Practitioners who tried the bifurcation strategy between the 2018 proposed regulations and the August 2018 final have largely unwound it. For the PLLC advisor in 2024, the planning room is around the threshold, not above it.

Malpractice insurance, which the boards make you carry anyway

State licensing boards do not treat the PLLC shield as a substitute for professional liability coverage, and in most of the regulated trades they require it directly. The New York Department of State's professional entity guidance and the Texas Medical Board's corporate practice rules each condition registration of the entity on evidence of professional liability coverage for each licensed member, in amounts set by board rule. Florida's Chapter 621 is more permissive, but the specialty boards that actually license dentists, architects, and professional engineers impose their own insurance floors as a condition of continued licensure.

The shield the PLLC provides is against the commercial liabilities of the practice and against the malpractice of other members, not against your own malpractice. That last point is load-bearing in every professional-entity statute in every state that recognizes the form. The entity does not indemnify the practitioner from the practitioner's own negligence. Insurance does, up to the limit.

The Corporate Transparency Act reaches every one of them

The Corporate Transparency Act, codified at 31 U.S.C. § 5336, treats any entity "created by the filing of a document with a secretary of state or a similar office" as a reporting company, and every PLLC is created by that kind of filing. FinCEN's final reporting rule at 87 Fed. Reg. 59498, published September 30, 2022, went live on January 1, 2024. A PLLC formed on or after that date has 90 days to file its initial beneficial-ownership information report; an entity formed in 2025 will have 30 days; a PLLC that existed before January 1, 2024 has until January 1, 2025 to file its initial BOI report.

The 23 exemptions in the statute are drawn from categories the PLLC does not occupy. The "large operating company" exemption under 31 U.S.C. § 5336(a)(11)(B)(xxi) requires more than 20 full-time employees in the United States, an operating presence at a physical office in the United States, and more than $5 million in gross receipts reported on the entity's prior federal tax return. A two-partner architecture PLLC does not clear that bar. The regulated-entity exemptions (banks, broker-dealers, registered investment advisers) do not reach professional practices. Tax-exempt entity status does not reach them. The PLLC, whether it is mandated in New York or optional in Florida, is a reporting company. Its beneficial owners, which will include at minimum every member with 25% or more ownership and every individual who exercises substantial control, file personal identifying information with FinCEN.

For practices that are a single licensed professional and a spouse who is a passive co-owner, the report is two individuals. For a five-partner engineering firm, it is five. For a medical group with a rotating membership, the 30-day updated report clock runs on every admission, departure, and change of controlling interest. Many of the calls professional-services attorneys have been getting through 2024 are not about whether the CTA applies to their PLLC client; it plainly does. They are about whether a forgotten administrative manager, a trust that holds a member's interest, or a parent holding company changes the list.

Where the form actually lands in 2024

The PLLC is not a tax instrument. It is the shape the state requires for a licensed practice that wants LLC-style governance and pass-through default treatment, and the federal tax code will sort that out through check-the-box no matter which state chartered the entity. The variation that actually matters in a cross-border practice is the board-level one: who can own a member interest, what the insurance floor is, what happens on death or license loss.

The new load-bearing variable since January 1, 2024 is not the state code at all. It is the FinCEN reporting calendar, which treats the PLLC the same way it treats a holding LLC or a dormant shell. For a two-person consultancy that filed in New York in 2018 and forgot about the entity between annual tax notices, January 1, 2025 is the deadline that will move the most filings. For a new PLLC forming this month, the 90-day clock on the initial BOI report starts at organization.
