Pennsylvania Limited Partnership FAQ

What exactly is a limited partnership?

A limited partnership is a business structure with two kinds of partners. General partners run the business and are personally liable for its debts. Limited partners put in money, share in profits, and stay out of management — and their liability is limited to what they invested. Every Pennsylvania LP needs at least one of each. That split between managing and investing is the entire point of the structure.

How is an LP different from an LLC?

In an LLC, all members can enjoy liability protection and still participate in management. In an LP, only the limited partners get liability protection, and only because they agree to stay passive; the general partner runs things and remains personally exposed. An LLC is the simpler, safer choice when everyone wants both protection and a say. An LP fits when there is a genuine division between operators and passive investors, and when a specific tax, estate-planning, or investment-fund reason calls for the partnership form.

How is an LP different from a general partnership?

A general partnership has no liability protection for anyone and requires no state filing to exist — it happens automatically when two or more people run a business together. An LP is a deliberate, filed entity that creates a class of protected, passive investors. If you want any partner to have limited liability, you need the LP, and you need to file the Certificate of Limited Partnership.

What do I file to create a Pennsylvania LP?

The Certificate of Limited Partnership, submitted to the Department of State, Bureau of Corporations and Charitable Organizations, through the portal at file.dos.pa.gov. It names the partnership, gives the Pennsylvania registered office, and identifies the general partners. The LP legally exists once the state accepts it.

Are limited partners named in the public filing?

No. Only the general partners appear on the Certificate of Limited Partnership. Limited partners, their contributions, and the deal terms stay in the private limited partnership agreement, which is never filed. This privacy is one reason investors like the LP form.

What are the naming rules?

Your LP's name must include a designator — "Limited Partnership," "L.P.," or "LP" — and must be distinguishable from other names on file with the Department of State. Restricted words implying banking, insurance, or licensed professions need extra approval. Check availability at file.dos.pa.gov/search/business before you file.

How long does formation take?

Standard online processing generally runs about five to seven business days. Pennsylvania offers expedited service, including same-day handling, for an additional state charge if you have a deadline.

Can a limited partner lose their protection?

Yes — that is the single most important risk to understand. A limited partner's liability shield depends on staying passive. If a limited partner starts managing the business, making operational decisions, or holding themselves out as able to bind the partnership, Pennsylvania may treat them as a general partner and expose them to the partnership's debts. The statute permits many "safe" activities — voting on major decisions, consulting, advising the general partner — but the boundary is real. When in doubt, a limited partner should stay clearly on the investor side of the line.

How do general partners protect themselves?

Since general partners carry unlimited personal liability, the common protective move is to make an LLC or corporation the general partner instead of an individual. That way the entity — not a person — holds the general-partner exposure, and no one's personal assets are on the line for partnership debts. It adds an entity to form and maintain, so weigh the benefit with your attorney.

Who can be a partner?

Both general and limited partners can be individuals or entities. There is no Pennsylvania residency requirement for partners. The people or companies involved simply need to fill the two roles the structure requires.

How is a Pennsylvania LP taxed?

By default, a limited partnership is a pass-through entity. It files a federal partnership return (Form 1065) and issues a Schedule K-1 to each partner showing their share of income, which the partners report on their own returns. The LP itself generally does not pay federal income tax. Pennsylvania taxes the partners on their share of Pennsylvania-source income. Your specific situation — including whether any partner should hold their interest through another entity for tax reasons — is a conversation for a CPA.

Does an LP need its own EIN?

Yes. Because an LP always has multiple partners and files a partnership return, it needs an Employer Identification Number regardless of whether it has employees. Apply free through the IRS at IRS.gov; the number issues immediately.

How are profits split?

However the limited partnership agreement says. Profit and loss allocation in an LP is heavily negotiated and often does not track ownership percentage — limited partners might receive a preferred return before general partners share in profits, for example. This is exactly why a written agreement matters: without one, statutory defaults govern, and they rarely match the deal the partners intended.

Does Pennsylvania require an annual report?

Yes, as of 2025. Pennsylvania replaced its old decennial (once-every-ten-years) report with an annual report requirement that now applies to limited partnerships. It is a short filing that keeps the state's record current — not a financial disclosure. Pennsylvania built in a grace period before penalties for missing it begin, but you should file on time regardless, because falling out of good standing creates problems the moment you try to borrow, sell, or open accounts.

What ongoing obligations does an LP have?

Keep a valid registered office on record, file the annual report, file the federal partnership return each year and issue K-1s to partners, and update the state whenever the general partners or registered office change. It is a light maintenance load compared to a corporation, but the annual report and registered office are the two you cannot let slide.

What happens if the LP goes out of compliance?

An out-of-compliance LP can lose its good standing, which shows up in due-diligence checks and can block financing and transactions. A lapsed registered office can lead to missed lawsuits and default judgments — and because general partners are personally liable, that exposure reaches them. Staying current on the registered office and the annual report prevents nearly all of it.
