Should my business be an LLC? Sole proprietor vs. LLC in Pennsylvania

If you run a business in your own name with no formal structure, you are a sole proprietor, and you are personally responsible for everything the business owes. A Pennsylvania LLC changes that for about $125 in state fees, but only if you run it like a separate business. Here is how the two compare and when the switch is worth it.

Sole proprietor: the default

• Nothing to file to start. You become a sole proprietor the day you start doing business on your own.
• A name filing if you use one. If you do business under a name other than your own, Pennsylvania requires a fictitious name registration. The state fee is $70.
• You and the business are the same. Business debts, contracts, and lawsuits reach your personal assets, including your house, savings, and vehicles.
• Taxes run through your personal return. Profit goes on Schedule C of your federal return, and you pay self-employment tax on it.

LLC: a separate legal entity

• Formed with the state. You file a Certificate of Organization with the Pennsylvania Department of State. The filing fee is $125.
• A Pennsylvania address on record. The LLC needs a registered office with a physical Pennsylvania address. A P.O. box does not qualify.
• An operating agreement. Pennsylvania does not require one, but you should have one. It sets out who owns what, who makes decisions, and what happens if an owner leaves or dies.
• A yearly report. Pennsylvania LLCs file an annual report by September 30. The fee is $7, and starting with the 2027 reports, an LLC that skips it can be dissolved.
• Liability stays with the business. In general, the LLC's debts and lawsuits stay with the LLC, and your personal assets are protected.

Taxes are mostly the same at first

By default, a single-member LLC is taxed just like a sole proprietorship. The IRS ignores the LLC for income tax, the profit still goes on Schedule C, and you still pay self-employment tax. In Pennsylvania, most LLCs pay no income tax of their own. The owners pay Pennsylvania personal income tax on their share of the profit.

The tax difference comes later, if you choose it. An LLC can elect to be taxed as an S-Corporation, which can lower self-employment tax for profitable owners who pay themselves a reasonable salary. A sole proprietorship cannot make that election.

The protection only holds if you keep it separate

An LLC on paper does not protect you if, in practice, the business and your personal finances are the same thing. To keep the protection:

• Open a business bank account in the LLC's name and run all business money through it.
• Sign contracts, invoices, and leases in the LLC's name, not your own.
• Keep the books current and do not pay personal bills from the business account.
• File the annual report and keep your registered office address up to date.

An LLC also does not protect you from everything. If you personally guarantee a loan or lease, you are still on the hook for it. You are also still responsible for your own professional mistakes, which is why insurance still matters.

When an LLC makes sense

• You have customers, employees, a vehicle on the road, or a physical location, so there is real risk of a claim.
• You sign contracts or leases, or plan to borrow.
• You are profitable enough that an S-Corporation election may be worth looking at.
• You have a partner. A multi-member LLC with an operating agreement is far better than an informal partnership on a handshake.

A sole proprietorship can still be reasonable for a side business with little risk and little income. Most growing businesses outgrow it.

How to switch

1. File the Certificate of Organization with the Department of State.
2. Get a new EIN for the LLC from the IRS if you will have employees or more than one owner, or if your bank requires one.
3. Sign an operating agreement.
4. Open the business bank account and move business activity into the LLC's name.
5. Update your licenses, insurance, payment processors, and vendor accounts.
