Going into business with someone else can be a smart move. You get another set of skills, extra money to work with, and a person to share the load. But a partnership is also a legal relationship, and it carries several risks if you don’t set it up properly. Many partners spend weeks on the business idea and almost no time on the paperwork behind it. Then a disagreement arises, and nobody is sure who has the final say. By that point, fixing the problem can cost far more than preventing it would have.
At Cali Law, we help business owners across Pennsylvania set up partnerships the right way from day one. We’ve seen how a good start can help protect both the business and the friendship or working relationship behind it. Below are the key steps to take before you start your business. Each step is simple, but together they can make a significant difference.
Choose the Right Type of Partnership
Pennsylvania offers four types of partnerships, and the one you pick determines how much of your own money is on the line.
General partnership (GP): This is the easiest partnership to set up, but it carries the most risk. If the business can’t pay what it owes, creditors can collect from the partners’ own assets.
Limited partnership (LP): An LP has two kinds of partners. General partners manage the business day-to-day and are fully liable for its debts. Limited partners contribute money but usually take no part in running the company, and the most they can lose is the amount they invested.
Limited liability partnership (LLP): In an LLP, you are not liable for debts that come from a fellow partner’s errors or misconduct. You are still liable for your own actions.
Limited liability limited partnership (LLLP): An LLLP mixes the LP structure with the protections of an LLP. This means even the general partners get some shield against personal liability.
Whichever of the four types you choose, the tax treatment is basically the same. The partnership itself doesn’t pay income tax. Its profits and losses flow through to the partners, who report them on their individual tax returns.
Pick and Register Your Business Name
If you’re forming an LP, LLP, or LLLP, your name has to include the type of partnership, like “LP” or “LLP.” Before you settle on a name, search to make sure it isn’t taken or too similar to another business’s name.
A general partnership that uses a name other than the partners’ last names must register a fictitious name with the Department of State. The filing fee is $70. You will also need to run a notice in two newspapers in your county, and one of them should be a legal newspaper where there is one. Keep proof of that advertisement in your business records.
File the Right Paperwork
Whether you need to register with the state depends on the type of partnership. A general partnership that operates under the partners’ own last names, such as “Smith & Jones,” can start doing business without filing anything. The other three types must submit paperwork before they open.
Limited partnership: File a Certificate of Limited Partnership.
LLP: File a Statement of Registration.
LLLP: File the same certificate as an LP filing, plus additional documents.
Pennsylvania also added a yearly filing in 2025. Most partnerships must now send an annual report to the State Department. The fee is $7, and the deadline is December 31 each year. Add the date to your calendar, since missing the deadline can cause legal problems for your business.
Write a Partnership Agreement
Pennsylvania does not require a written partnership agreement. Even so, it is probably the most important document you can have. Without one, the state’s default rules under the Pennsylvania Uniform Partnership Act determine what happens in certain situations, and they may not match what you and your partner had in mind.
Discuss the Hard Questions Early
Most partnership trouble starts with mismatched expectations, not legal problems. Sit down together and talk about who does what, how many hours each of you will put in, how much money each person is putting in and getting, and what happens if one of you wants out.
Plan for How the Business Might End
Nobody likes to think about the end of a partnership when they are just getting started, but this is where a plan can be most helpful. Pennsylvania law lists certain events that cause a partnership to dissolve, and your agreement can spell out what happens next.
Decide ahead of time how the business will be valued, who gets to buy out whom, and how debts and leftover assets will be handled. If a partner dies or wants to leave, a clear process can help the business keep running rather than ending up in a fight.
Get Your Tax ID and Bank Account in Order
Apply for an Employer Identification Number (EIN) for free through the IRS even if you are not planning to hire. You will usually need this number to open business bank accounts. If you hire employees in Pennsylvania, you will also need to register for state employment taxes and carry workers’ compensation insurance. Some trades, like plumbing and electrical work, need licenses too.
Additionally, after receiving the approved paperwork, open a bank account in the partnership’s name and keep personal spending separate from it.
Starting a partnership takes more than a good idea and a handshake. Choosing the right structure, filing the right paperwork, and putting your agreement in writing all work together to protect your money and your relationship with your partner. Take the time to get it right now, and you will have a much stronger foundation for everything that comes next.
