What Is a Professional Corporation for an Attorney?
A professional corporation, or PC, is a state-authorized business entity that lets attorneys provide legal services through a corporation. It can create a formal structure for ownership, management, compensation, and business finances, but it does not eliminate an attorney’s personal responsibility for professional misconduct or malpractice. Because state laws and bar rules differ, a lawyer considering a PC must check both the applicable corporate requirements and the rules governing the practice of law.
What Is a Professional Corporation?
A professional corporation is a corporation formed to provide a licensed professional service, such as law, medicine, or accounting. For an attorney, it is a legal business entity separate from its owners, which are generally called shareholders. States typically regulate professional corporations through specific statutes, licensing rules, and filing requirements.
A PC is not simply a regular corporation with a different label. Its permitted services and ownership are often restricted to people holding the appropriate professional licenses. In many states, a law-firm PC must be owned by lawyers, although the details—including whether lawyers licensed in other states may hold shares—vary. Some jurisdictions allow certain licensed professionals to share ownership in defined circumstances; others impose tighter limits.
The corporation can enter contracts, hire employees, own business property, and receive fees for legal services, subject to state law and professional-conduct rules. An attorney’s choice of entity does not replace the obligation to comply with rules on client confidentiality, conflicts of interest, trust accounts, advertising, fee arrangements, and supervision.
How an Attorney PC Works
After forming the PC, its owners generally adopt governing documents, select directors or officers as required, and establish procedures for making business decisions. A small practice may have one attorney serving in several roles. The corporation may employ attorneys and staff, lease office space, maintain business accounts, and handle operating expenses.
The PC and the individual lawyer remain distinct for many business and legal purposes, but professional regulation still applies to the people providing legal services. Clients retain the right to hold an attorney responsible for that attorney’s own conduct. The entity’s paperwork does not convert a lawyer’s professional judgment into a purely corporate decision or remove the lawyer’s duties to clients.
State law can also determine who may receive fees, how shares can be transferred, and what happens if a shareholder loses a license, dies, or leaves the firm. A PC’s governing documents should address these events in a way that fits the state’s professional-corporation statute and ethics rules.
How to Form a Professional Corporation for a Law Practice
The steps depend on the state, but forming a PC commonly involves the following tasks. Filing requirements should be confirmed with the state business-registration agency and the relevant state bar or licensing authority.
- Check state eligibility rules. Confirm that the proposed owners and service qualify under the state’s professional-corporation law. Review naming, licensing, and ownership restrictions.
- Choose an available name. State law may require a designation such as “Professional Corporation,” “P.C.,” or “PC.” Bar rules may impose separate requirements so that the name is not misleading about the firm’s services, lawyers, or organizational status.
- File formation documents. Submit the required articles or certificate of incorporation to the state. Some states also require approval, registration, or evidence of professional licensure.
- Adopt corporate records. Prepare bylaws, issue authorized shares, appoint directors and officers, and document initial actions. The required structure depends on state law and the number of owners.
- Register for tax and employment obligations. Obtain an employer identification number when required, establish payroll procedures, and register for applicable state and local taxes.
- Set up firm operations. Open appropriate business accounts, review insurance, update client engagement materials, and confirm that trust-account arrangements meet state rules.
- Maintain the entity. File annual reports and taxes, keep required records, renew professional licenses, and follow applicable corporate formalities.
Formation is only one part of the process. A lawyer should also consider how existing clients, contracts, leases, insurance policies, and outstanding obligations will be handled when a practice changes its legal structure.
What Liability Protection Does a PC Provide?
A professional corporation may help separate certain business liabilities from an owner’s personal assets. For example, depending on state law and the facts, the corporate structure may help protect an individual shareholder from some debts or obligations incurred by the corporation. That protection is not automatic in every situation and is not a substitute for insurance or careful business practices.
A PC generally does not shield an attorney from personal liability for the attorney’s own malpractice or professional misconduct. If a lawyer personally handles a matter negligently, the lawyer may remain personally liable even when the client’s engagement is with the PC. Other attorneys in the firm may also face exposure depending on their own conduct, supervisory responsibilities, applicable law, and the circumstances of the claim.
Nor does incorporation necessarily protect an owner from personal guarantees, the owner’s own torts, certain employment or tax obligations, or liability arising from misuse of the corporation. Courts may also disregard an entity in some circumstances, such as when it is not treated as a separate business. The specific rules are state- and fact-dependent.
Professional liability insurance remains an important risk-management tool. Coverage, limits, exclusions, and reporting requirements differ by policy, so a firm should review its coverage with a qualified insurance professional. A PC should be viewed as an organizational and financial structure—not as a malpractice shield.
Tax Treatment of an Attorney PC
A professional corporation’s tax treatment is not determined solely by the letters “PC.” A corporation is generally subject to federal corporate tax rules unless it makes an eligible election. Depending on the entity’s qualifications and timely filings, the owners may be able to elect S corporation tax treatment. Some PCs instead retain C corporation tax treatment.
Under the general federal rules, a C corporation pays tax on its taxable income, and shareholders may also owe tax on dividends they receive. An eligible corporation that elects S status generally passes income, losses, deductions, and credits through to shareholders for federal tax purposes, subject to the applicable rules. S corporation owners who work in the business may need to receive reasonable compensation as employees before certain profits are treated as distributions.
Tax results can depend on state law, the corporation’s income, shareholder circumstances, payroll, retirement plans, and the timing of elections. State and local taxes may differ from federal treatment. A lawyer should consult a tax professional before selecting an entity or making an election; a PC does not automatically produce tax savings.
PC vs. LLC or PLLC for Attorneys
Attorneys often compare a PC with a limited liability company (LLC) or professional limited liability company (PLLC). The available choices depend on the state. Some states permit law firms to operate as LLCs or PLLCs, while others require or favor a professional corporation for certain licensed services. State bar rules apply regardless of the entity selected.
| Feature | Professional Corporation (PC) | LLC or PLLC |
|---|---|---|
| Legal structure | Corporation formed under state professional-corporation law | Limited liability company formed under state LLC or professional-LLC law |
| Ownership | Often restricted to licensed professionals; exact rules vary | May be restricted for professional services; rules vary by state |
| Management | Typically uses corporate roles and records, as required by law | Typically managed by members or appointed managers, under an operating agreement |
| Federal tax treatment | Generally taxed under corporate rules unless an eligible election applies | Often taxed by default as a disregarded entity or partnership, depending on ownership, with possible corporate elections |
| Professional liability | Does not generally protect a lawyer from liability for the lawyer’s own malpractice | Does not generally protect a lawyer from liability for the lawyer’s own malpractice |
The table describes common federal and organizational patterns, not a guarantee of how a particular state treats a law practice. An LLC or PLLC may offer different management flexibility, while a PC may fit a state’s professional-entity framework. Tax treatment and liability consequences should be assessed separately from the entity’s name.
Professional Conduct Still Governs the Firm
Creating a PC does not change the attorney’s professional obligations. The American Bar Association’s Model Rules of Professional Conduct provide a widely used model, but they are not binding by themselves. Each state adopts its own rules, which may differ from the ABA model.
Relevant duties can include protecting client information, avoiding conflicts, communicating with clients, safeguarding property, supervising lawyers and nonlawyer staff, and ensuring that fees and advertisements are not misleading. The entity must also handle client funds according to the jurisdiction’s trust-account rules. For example, operating funds and client trust funds generally require appropriate separation and accounting, though the precise requirements are set by state rules.
Ownership and nonlawyer participation are particularly important. The ABA Model Rule 5.4 generally restricts sharing legal fees with nonlawyers and allows nonlawyer ownership or control of a law firm only in limited circumstances under the model framework. State rules may differ. A PC’s shareholders, officers, and compensation arrangements should therefore be reviewed for compliance with the jurisdiction’s current professional-conduct rules.
Advantages and Limitations of an Attorney PC
Potential advantages
- Formal business structure: A corporation can clarify ownership, authority, and decision-making through shares and corporate governance documents.
- Separate business identity: The PC can conduct many business activities in its own name, subject to state law.
- Possible tax flexibility: An eligible PC may be able to choose among tax treatments, although the best option depends on individual circumstances.
- Continuity and transfer planning: Corporate records and share-transfer provisions can help define what happens when an owner joins, leaves, or retires, within professional-ownership limits.
Potential limitations
- State-specific restrictions: Formation, ownership, naming, and reporting rules differ across jurisdictions.
- Administrative work: Corporate records, filings, payroll, and tax compliance can add costs and responsibilities.
- No malpractice immunity: The attorney remains accountable for the attorney’s own professional acts and omissions.
- Tax complexity: Payroll, distributions, state taxes, and elections can require professional advice and ongoing administration.
Questions to Ask Before Choosing a PC
Before forming an attorney PC, the lawyer should identify the state in which the entity will be organized and every jurisdiction where the firm will practice. The firm should verify whether those jurisdictions recognize the entity, what professional approvals are required, and whether ownership and naming rules affect the proposed structure.
Useful questions include: Does state law permit a PC for legal services? Who may own shares? Is a separate bar or licensing filing required? Which tax treatment is available and appropriate? How will malpractice coverage respond to the new entity? What corporate records and annual filings are required? How will client funds, existing engagements, and responsibility for ongoing matters be handled?
Reliable starting points include the relevant state’s business-entity statute and filing agency, its current professional-conduct rules, and guidance from the state bar.
