What is a PLLC?
A PLLC, or professional LLC, is an LLC built for state-licensed professions, doctors, lawyers, accountants, engineers, where the state requires licensed ownership and often board approval to deliver professional services. A regular LLC is often rejected for licensed work. We confirm whether your profession needs a PLLC and form it correctly.
How is a PLLC different from a regular LLC?
Structurally similar, professionally stricter: a PLLC requires that owners hold the relevant license and that the licensing board approve the filing, and its liability shield covers business debts and other members' malpractice but not your own professional negligence. We set it up so the entity and the required insurance work together. See how LLCs work.
Which professions need a PLLC?
It varies by state, but the usual list includes fields the state licenses: medicine, law, accounting, architecture, engineering, therapy, and similar. Some states require these professionals to use a PLLC or professional corporation and reject a standard LLC. We check your state's rule for your specific license.
Can non-licensed people own a PLLC?
Usually not: most states require every member, or a controlling share, to hold the relevant professional license, which blocks non-licensed investors or a spouse from being an owner. Getting this wrong invalidates the entity. We verify your state's ownership rule so your cap table complies.
Does a PLLC protect me from malpractice?
Only partly: it shields your personal assets from business debts and a co-owner's malpractice, but not from your own professional negligence, which is why states require malpractice insurance. The entity and the policy cover different risks, and we set both up so they work together. See asset protection.
How is a PLLC taxed?
Like any LLC: pass-through by default, with the option to elect S-corp treatment once profit justifies it. The professional designation affects licensing and ownership, not the tax classification. We help you pick the tax treatment that fits a profitable practice.
Do I need an Operating Agreement for a PLLC?
Yes, and a stronger one: beyond the usual terms, a PLLC Operating Agreement addresses what happens if a member loses their license, dies, or leaves the profession, since ownership is tied to licensure. We draft a PLLC-specific agreement so the practice and remaining members are protected.
Can I convert my regular LLC to a PLLC?
Often yes where the state allows, by amending to meet the professional requirements, confirming licensed ownership, and obtaining board approval. If you have been practicing through a standard LLC, correcting the structure matters. We handle the conversion so the entity and license align properly.
Does File.Business form PLLCs?
Yes: we confirm the professional entity your state requires, prepare the filing, coordinate any licensing-board approval, obtain the EIN, and draft the professional operating agreement, so your licensed practice operates through the entity the state actually requires.
