How to Form a PLLC in Kentucky: A Guide for Medical, Legal, and Accounting Professionals

Opening a private clinical practice in Louisville, launching an accounting consultancy in Lexington, or establishing a boutique law firm in Covington requires more than a standard commercial business filing. When state-licensed practitioners inadvertently register an ordinary limited liability company instead of a specialized professional entity, they risk administrative rejection, disciplinary scrutiny from their state regulatory board, and complications with professional malpractice insurers. Kentucky law provides specific statutory vehicles designed to balance personal asset protection with the strict ethical accountability required of licensed specialists.

In the Commonwealth of Kentucky, licensed professionals generally choose between forming a Professional Limited Liability Company (PLLC) under Ky. Rev. Stat. Ann. § 275.015(25) or a Professional Service Corporation (PSC) under Ky. Rev. Stat. Ann. § 274.015. While both structures shield owners from commercial business debts-such as office leases, medical equipment financing, and slip-and-fall claims-a PLLC offers superior management flexibility and fewer rigid corporate formalities. This guide walks physicians, dentists, certified public accountants, and attorneys through the exact statutory steps, licensing board rules, and state filings required to launch a compliant Kentucky PLLC.

Understanding the Kentucky PLLC Liability Shield

Before submitting formation paperwork, professionals must understand what a Kentucky PLLC protects-and what it does not. Under Ky. Rev. Stat. Ann. § 275.150(1), members and managers of a PLLC are not personally liable for the commercial debts, contractual obligations, or general liabilities of the company solely by reason of acting as a member or manager. The strength of this commercial shield was reinforced by the state's highest court in Pannell v. Shannon, 425 S.W.3d 58 (KY Supreme Court 2014), where the court ruled in favor of an LLC member and held that statutory immunity protects owners from personal liability on commercial leases executed in the entity's name.

However, Ky. Rev. Stat. Ann. § 275.150(2) carves out a critical professional exception: forming a PLLC does not shield an individual practitioner from personal liability for their own professional negligence, wrongful acts, or misconduct, nor does it shield them from the malpractice of subordinates working under their direct supervision and control. What a PLLC does prevent is vicarious personal liability for the malpractice of a co-owner or partner whom you did not supervise or participate with in the negligent service. Furthermore, to preserve the entity's commercial liability shield, members must avoid commingling personal and practice funds; in Inter-Tel Technologies, Inc. v. Linn Station Properties, LLC, 360 S.W.3d 152 (KY Supreme Court 2012), the court ruled in favor of a commercial creditor and pierced the entity veil where owners dominated the company and ignored separate financial existence to promote an injustice.

Licensing Board Requirements by Profession

Unlike standard commercial businesses, a Kentucky PLLC is governed simultaneously by the Kentucky Secretary of State, Division of Business Filings, Frankfort and the specific state regulatory board that issues your professional license. Under Ky. Rev. Stat. Ann. § 275.015(26), covered professional services include physicians, surgeons, osteopaths, dentists, chiropractors, optometrists, podiatrists, psychologists, certified public accountants, attorneys, architects, professional engineers, veterinarians, and nurses. Each discipline imposes distinct ownership and post-formation registration rules.

PLLC Rules for Doctors and Dentists

Physicians regulated by the Kentucky Board of Medical Licensure, Louisville (located at 310 Whittington Parkway, Suite 1B, Louisville, KY 40222, phone (502) 429-7150) and dental practitioners overseen by the Kentucky Board of Dentistry, Louisville (312 Whittington Parkway, Suite 101, Louisville, KY 40222, phone (502) 429-7280) must navigate Kentucky's corporate practice of medicine and dentistry doctrines. While forming an older-style Professional Service Corporation requires obtaining a pre-filing regulatory certificate under Ky. Rev. Stat. Ann. § 274.017, the Kentucky Secretary of State does not require physicians or dentists to attach a pre-approval certificate from their licensing board when filing PLLC Articles of Organization.

Despite the streamlined Secretary of State filing, strict licensing rules still govern internal ownership and clinical operations:

• Qualified Member Ownership: To comply with professional ethics rules under Ky. Rev. Stat. Ann. § 311.595 for medicine and Ky. Rev. Stat. Ann. § 313.035 for dentistry, voting membership interests and clinical decision-making authority must remain exclusively in the hands of individuals actively licensed to practice that healing art in Kentucky.
• Multi-Disciplinary Medical Practices: Kentucky allows allied healthcare professionals-such as physicians, osteopaths, psychologists, and podiatrists-to co-own a single PLLC, provided each member holds an active Kentucky license for the specific clinical service they render and no unlicensed layperson exercises control over medical judgment.
• DEA, NPI, and Facility Updates: Once the PLLC is registered in Frankfort, medical and dental practices must apply for a Type 2 Organizational National Provider Identifier (NPI), update their Medicare PECOS and Kentucky Medicaid provider enrollments, and register dental office locations with the dental board.

Formation Guidelines for CPA Firms

Public accounting practices in Kentucky are strictly regulated by the Kentucky State Board of Accountancy, Louisville (332 W. Broadway, Suite 310, Louisville, KY 40202, phone (502) 595-3037). Under Ky. Rev. Stat. Ann. § 325.301, forming a PLLC with the Secretary of State is only the first half of the compliance equation; an accounting entity cannot legally perform attest services or use the designation 'CPA' in its firm name until it obtains a separate Firm License from the Board of Accountancy.

When structuring an accounting PLLC in Kentucky, organizers must satisfy these statutory mandates:

• The 51% CPA Majority Rule: Under Ky. Rev. Stat. Ann. § 325.301(3)(a), certified public accountants holding active licenses must own at least 51% of the financial interests and voting rights of the PLLC.
• Non-CPA Minority Owners: Unlike law or medical firms, Kentucky permits up to 49% non-CPA ownership in an accounting PLLC under Ky. Rev. Stat. Ann. § 325.301(3)(b), provided that all non-licensed owners are natural persons (not passive holding companies) who are actively engaged in the daily operations of the firm.
• CPA Firm Naming Restrictions: Under Ky. Rev. Stat. Ann. § 325.380, a firm name may not be misleading and cannot include the name of an individual who is neither a current nor a retired/deceased CPA member unless the firm meets specific statutory continuity rules.
• Post-Formation Board Registration: Immediately after the Secretary of State approves the PLLC, the designated CPA firm manager must submit the In-State Firm Application and a non-refundable $100 firm license fee to the Board of Accountancy pursuant to Ky. Rev. Stat. Ann. § 325.301(4).

Setting up a Law Practice PLLC

In Kentucky, the practice of law falls under the exclusive constitutional authority of the Supreme Court of Kentucky, Frankfort and is administered through the Kentucky Bar Association, Frankfort (514 W. Main Street, Frankfort, KY 40601, phone (502) 564-3795). Attorneys are expressly authorized to practice law through a PLLC under Ky. Sup. Ct. R. 3.022(e), but doing so triggers mandatory financial responsibility requirements under Ky. Sup. Ct. R. 3.024.

To maintain limited liability protection for co-member malpractice, a Kentucky law practice PLLC must comply with three non-negotiable rules:

• Zero Non-Lawyer Ownership: Pursuant to the Kentucky Rules of Professional Conduct (Ky. Sup. Ct. R. 3.130(5.4)), no membership interest, manager role, or profit-sharing right in a law practice PLLC may be held by a non-lawyer. Every member and manager must be an active attorney licensed to practice law.
• Mandatory Malpractice Insurance Floors: Under Ky. Sup. Ct. R. 3.024, to enjoy the shield against vicarious liability for another partner's errors, the PLLC must maintain professional liability insurance of at least $50,000 per claim and $100,000 aggregate per policy year multiplied by the number of attorneys in the firm, subject to an absolute firm minimum of $250,000 per claim and $500,000 aggregate per policy year (or an equivalent irrevocable letter of credit or segregated escrow deposit).
• IOLTA Trust Account Setup: After receiving its PLLC Articles of Organization and federal EIN, the firm must establish a compliant Interest on Lawyers' Trust Accounts (IOLTA) escrow account with an approved financial institution in compliance with Ky. Sup. Ct. R. 3.830.

Step-by-Step Process to Form a PLLC in Kentucky

Whether your practice is based in Louisville, Lexington, Bowling Green, or Northern Kentucky, forming a domestic PLLC follows a standardized sequence governed by Ky. Rev. Stat. Ann. § 275.020 and the Kentucky Business Entity Filing Act (Ky. Rev. Stat. Ann. § 14A.2-010).

Step 1: Select a Compliant Professional Entity Name

Under Ky. Rev. Stat. Ann. § 14A.3-010(3), the legal name of a Kentucky PLLC must be distinguishable upon the records of the Secretary of State from any other registered business name and must contain one of the following exact designators: 'Professional Limited Liability Company', 'Professional Limited Company', 'PLLC', 'P.L.L.C.', 'PLC', or 'P.L.C.'. If you wish to lock in your practice name for 120 days while finalizing licensing board paperwork, you may submit Form RES, Kentucky, Secretary of State, Reservation or Renewal of Reserved Name along with a $15 filing fee.

Step 2: Appoint a Kentucky Registered Agent

Pursuant to Ky. Rev. Stat. Ann. § 14A.4-010, every PLLC must continuously maintain both a registered office with a physical street address in Kentucky (P.O. boxes are strictly prohibited) and a registered agent who is either an individual Kentucky resident or a domestic/foreign business entity authorized to transact business in the Commonwealth. Critically, under Ky. Rev. Stat. Ann. § 14A.2-070, the appointed registered agent must sign the consent statement on the Articles of Organization before the state will accept the filing.

Step 3: File Form PLC (Articles of Organization)

Do not use the standard LLC form (Form KLC). Professional entities must file Form PLC, Kentucky, Secretary of State, Articles of Organization Professional Limited Liability Company with the Kentucky Secretary of State, Division of Business Filings, Frankfort (Room 154, Capitol Building, 700 Capital Avenue, Frankfort, KY 40601). Under Ky. Rev. Stat. Ann. § 275.025(3), Article I of this form requires you to explicitly state the exact professional service(s) to be practiced through the PLLC (for example, 'the practice of medicine and surgery' or 'the practice of law'). You must also designate whether the PLLC will be member-managed or manager-managed and pay the $40 state filing fee online via the Kentucky Business One Stop FastTrack portal or by mail.

Step 4: Record a Copy with the Local County Clerk

After the Secretary of State approves and stamps your Form PLC, Kentucky, Secretary of State, Articles of Organization Professional Limited Liability Company, check local recording requirements in the county where your registered office is situated, such as the Jefferson County Clerk's Office, Louisville, the Fayette County Clerk's Office, Lexington, or the Kenton County Clerk's Office, Covington. If your practice operates under a clinic or trade name different from its exact legal PLLC name, you must first file Form ASN, Kentucky, Secretary of State, Certificate of Assumed Name ($20 fee) with the Secretary of State under Ky. Rev. Stat. Ann. § 365.015 and record a file-stamped copy with the county clerk.

Step 5: Draft a Professional Operating Agreement

While not filed with the state, a customized PLLC Operating Agreement governed by Ky. Rev. Stat. Ann. § 275.175 is essential for a professional practice. Unlike a standard commercial operating agreement, a PLLC agreement must include mandatory buy-sell triggers that automatically force the redemption or transfer of a member's ownership interest if that member dies, becomes disqualified, or has their professional license suspended or revoked by a Kentucky regulatory board.

Step 6: Obtain an EIN and Register for Kentucky Taxes

Once your PLLC is formed, obtain a Federal Employer Identification Number (EIN) using Form SS-4, Federal, IRS, Application for Employer Identification Number. Next, register the practice with the Kentucky Department of Revenue, Frankfort using Form 10A100, Kentucky, Department of Revenue, Kentucky Tax Registration Application to set up employer withholding accounts and your Limited Liability Entity Tax (LLET) account. Finally, submit your entity details to your professional licensing board (such as the CPA Firm License application or KBA insurance certification).

Comparing a Kentucky PLLC vs. Professional Service Corporation (PSC)

Licensed professionals in Kentucky often weigh whether to organize as a PLLC under Chapter 275 or as a traditional Professional Service Corporation (PSC) under Chapter 274 using Form PSC, Kentucky, Secretary of State, Articles of Incorporation Professional Service Corporation. The table below outlines the statutory differences.

How Much Does It Cost to Form a PLLC in Kentucky?

Kentucky offers one of the lowest initial state filing fees in the United States, though professional practices must budget for recurring tax obligations and licensing fees:

• Secretary of State Articles of Organization (Form PLC): $40 flat filing fee (waived to $0 for qualified veteran-owned businesses under Ky. Rev. Stat. Ann. § 14A.2-165).
• Optional Name Reservation (Form RES): $15 for a 120-day reservation.
• Assumed Name Registration (Form ASN, if applicable): $20 state fee plus local county clerk recording fees (typically $10 to $46 depending on the county).
• State Licensing Board Firm Fees: $0 to $100+ depending on your profession (for example, $100 for a CPA firm permit with the Kentucky State Board of Accountancy).
• Annual Report Fee: $15 per year, due to the Secretary of State between January 1 and June 30 starting the calendar year after formation under Ky. Rev. Stat. Ann. § 14A.6-010.
• Kentucky Limited Liability Entity Tax (LLET): Minimum $175 per year payable to the Kentucky Department of Revenue, Frankfort under Ky. Rev. Stat. Ann. § 141.0401(2)(a) for all limited liability pass-through entities.
• Legal Counsel & Custom Operating Agreement: Typically $750 to $2,500 when hiring a Kentucky business attorney to draft board-compliant buy-sell and disqualification provisions.

How Long Does the PLLC Formation Process Take?

Filing Form PLC, Kentucky, Secretary of State, Articles of Organization Professional Limited Liability Company online through the Kentucky Business One Stop FastTrack portal is typically approved within 1 to 3 business days, and often on the same business day if submitted during normal Frankfort business hours. Mailed paper filings generally take 5 to 7 business days plus postal transit time. However, professionals who require post-formation board credentials-such as CPA firm licenses, DEA registrations, or insurance underwriting under Ky. Sup. Ct. R. 3.024-should allow 3 to 6 weeks for full operational readiness.
