What forming a Professional LLC in Connecticut actually involves.
Connecticut PLLC status
Connecticut permits PLLC for licensed professionals.
All members must be licensed
Most states require every member of a PLLC to hold an active license in the profession the entity will practice. Adding a non-licensed business partner usually disqualifies the PLLC; that partner would need to be structured separately.
Liability protection limits
A PLLC protects each member from the malpractice of other members and from general business debts, but does NOT protect a member from their own personal malpractice. Professional liability insurance covers the gap.
Connecticut licensing board approval
Connecticut requires the relevant state licensing board (medical board, bar association, board of accountancy, board of architects, etc.) to approve the entity formation. The Articles often have to be signed off before the SOS will accept the filing.
Federal tax treatment
PLLCs are treated the same as regular LLCs for federal tax: disregarded entity (single-member), partnership (multi-member), or S-Corp / C-Corp by election. Professional services income is not treated differently by the IRS based on entity type.
Naming requirements
PLLC name in Connecticut must include the entity suffix ("PLLC", "P.L.L.C.", or "Professional Limited Liability Company") and may need to include the profession. Most licensing boards have specific naming rules on top of Connecticut SOS rules.
A clean handoff, in 7 steps.
Confirm your license is current
Most Connecticut licensing boards will not approve the entity formation if your individual professional license is delinquent, suspended, or on probation.
Pick the right entity for Connecticut
PLLC is the standard for most professions in Connecticut. Verify with your specific licensing board whether they prefer PLLC, regular LLC, or Professional Corporation.
Get licensing board approval
The Connecticut board that regulates your profession typically reviews the formation paperwork before the SOS accepts the filing. Submission process varies by board.
File Articles with Connecticut SOS
We prepare the Professional LLC Articles with the Connecticut Secretary of State. State filing fee passes through.
Get your EIN
The IRS issues an EIN to the PLLC just like any other LLC. We file Form SS-4 after Connecticut accepts the entity.
Set up professional liability insurance
Malpractice insurance is the layer that covers the gap PLLC does not protect against (your own professional negligence). Most states require evidence of coverage before the licensing board will activate the entity to practice.
Stay current on board reporting
Most Connecticut licensing boards require annual or biennial reporting of entity status, member changes, address changes, and continuing education. The Compliance Bundle tracks these alongside the standard Connecticut annual report.

Common questions.
Does Connecticut permit a PLLC for licensed professionals?
Most states offer a professional LLC for licensed occupations, but the rules vary, so the first step is confirming Connecticut recognizes the PLLC and which board must sign off. Some states route licensed professionals into a PLLC or a professional corporation instead of an ordinary LLC. We verify Connecticut's exact requirement for your profession before filing so the entity is accepted the first time.
What is the difference between a PLLC and a regular LLC in Connecticut?
A PLLC is an LLC built for state-licensed professions, so on top of normal formation it usually requires that the owners hold the relevant Connecticut license and that the licensing board approve the filing. Liability protection works like a regular LLC for business debts and other members' malpractice, with one key exception: it does not shield you from your own professional negligence. Structurally similar, professionally stricter.
Which professions require a PLLC in Connecticut?
It depends on Connecticut, but the usual list covers fields the state licenses: doctors, dentists, lawyers, accountants, architects, engineers, therapists, and similar. Some states require these professionals to use a PLLC or professional corporation and will reject a standard LLC; others make it optional. Because the list and the rule are Connecticut-specific, we check whether your license triggers a PLLC there.
Can I have a non-licensed partner in my Connecticut PLLC?
Usually not, and this trips people up. Many states require every member, or a controlling share, of a PLLC to hold the same professional license, which blocks bringing in a non-licensed investor or spouse as an owner. Connecticut may allow limited exceptions or a different structure for outside capital. We confirm Connecticut's ownership rule so you do not build a cap table the board will reject.
Does a PLLC protect me from malpractice claims?
Only partly, and it is important to understand where the line is. A PLLC shields your personal assets from the business's debts and from another member's malpractice, but it does not protect you from liability for your own professional negligence, which is why Connecticut typically also requires malpractice insurance. Think of the PLLC and your policy as two different layers of protection doing two different jobs.
How is a PLLC taxed in Connecticut?
A PLLC is taxed like any LLC: pass-through by default, with the option to elect S-corp treatment once the numbers justify it. The professional designation changes the licensing and ownership rules, not the tax classification. Many established practices elect S-corp status to manage self-employment tax, which we can walk through for your specific Connecticut situation.
Do I need an Operating Agreement for my Connecticut PLLC?
Yes, and it should go further than a standard one. Beyond the usual ownership and management terms, a PLLC Operating Agreement addresses what happens if a member loses their license, dies, or leaves the profession, since Connecticut ties ownership to licensure. Getting these provisions right protects both the practice and the remaining members. We draft a PLLC-specific agreement for Connecticut.
How much does PLLC formation cost in Connecticut?
The base is the Connecticut formation fee plus our service, but a PLLC often adds a licensing-board review or certification step that a regular LLC skips, and you should budget for required malpractice insurance separately. Current Connecticut figures and our pricing are on the pricing page. The extra cost is mostly the board approval, not the filing itself.
Can I convert my regular Connecticut LLC to a PLLC later?
Often yes, where Connecticut allows it, by amending the entity to meet the professional requirements, confirming all owners are licensed, and obtaining board approval. It is not just a name change: the state has to recognize the conversion and the ownership has to comply. If you have been operating a licensed practice through a standard LLC, we help you correct the structure to a proper Connecticut PLLC.
