Starting & Structuring a Business

Choosing the right entity structure is one of the most consequential decisions a business owner makes. It affects taxes, liability, succession, and your ability to raise capital. Pennsylvania recognizes several entity types, each with distinct advantages:
Limited Liability Company (LLC). The default choice for most small businesses. An LLC provides personal liability protection while allowing pass-through taxation. Pennsylvania LLCs are formed by filing a Certificate of Organization with the Department of State ($125 online). An operating agreement (while not required by law) is essential. Without one, the PA Uniform Limited Liability Company Act of 2016 (15 Pa.C.S. Ch. 88) supplies default rules that may not match your intentions.
Corporation (C-Corp or S-Corp): Appropriate for businesses planning to raise outside investment or with multiple shareholders. C-Corps are subject to double taxation (corporate + individual). S-Corp election (IRS Form 2553) avoids double taxation but limits you to 100 domestic shareholders. PA imposes a corporate net income tax (currently 7.49% for 2026, decreasing annually to 4.99% by 2031 under HB 1342 (2022)).
Five ways to hold a business in Pennsylvania, ordered roughly by how often they are the right answer. The two that cost nothing to form are the two that expose you personally.
General guidance only, not legal advice. Formation cost is the state filing fee only, not the cost of doing it properly, and it is the smallest number in this decision. The right entity depends on your liability exposure, your income, whether you have partners, and whether you plan to raise money. An LLC that is not maintained will not protect you. Talk to a lawyer and an accountant together before choosing.
General Partnership: Formed automatically whenever two or more people conduct business together for profit. This is dangerous: each partner has unlimited personal liability for all partnership debts and obligations. If you are operating with a partner and have not formed an LLC, you are a general partnership, whether you intended to be or not.
Limited Partnership (LP): Common in real estate and investment structures. General partners manage and bear unlimited liability; limited partners invest and have liability limited to their investment. Requires filing with the Department of State.
Sole Proprietorship. No formation required, no liability protection. The owner and the business are legally identical. Fine for very low-risk ventures, but for most businesses, the modest cost of forming an LLC is well worth the protection.
⚠ About Online Formation Services
Online formation services will file your Certificate of Organization, but they typically skip the operating agreement, miss PA tax registrations, and do not mention the annual report filing requirement ($7/year). If you have already formed an entity through one of these services, I can review what you have and fill the gaps. See our AI-Generated Legal Documents section in Estate Planning for a full breakdown of what these tools get wrong in Pennsylvania.
