LLC or sole proprietor for a Pennsylvania notary

What the structure choice decides for a signing agent

The structure decides who owes the business's debts and how its profit is taxed. It never decides who holds the notary commission, which stays with you.

That is the frame for every option below. A signing agent's biggest personal risks come from notarial mistakes, and those follow the commission. The structure governs the rest: vendor contracts, equipment leases, a dispute over an unpaid invoice, a car used for the business.

So the question is narrower than it looks. You are not choosing how to protect the stamp. You are choosing how to hold everything around it. The commission and company page draws that line in detail.

The sole proprietorship, the default with no filing

If you start signing under your own name and file nothing, you are a sole proprietor. It costs nothing to set up and nothing each year at the state level.

Taxes are simple. Profit goes on Schedule C of your personal return. Self-employment tax applies to net earnings of $400 or more, except that notary fees themselves are excluded.

The cost is exposure. Every business obligation is personally yours. That can be acceptable for a part-time notary doing a few signings a month with no leases or staff. It gets harder to justify once the business carries contracts, a printer lease or a second person.

Want a brand? A sole proprietor trading under anything but a full personal name needs a $70 fictitious name registration. That label gives no liability protection.

The single-member LLC for a signing business

A single-member LLC separates business debts from your personal assets. It costs $125 to form and $7 a year for the annual report.

For federal tax, it changes little by default. The IRS ignores a single-member LLC unless it elects otherwise, so profit still lands on your return. Self-employment tax works the same way it would for a sole proprietor.

The benefit is the wall around business obligations. A signing service contract, an office lease or a disputed bill belongs to the company. Keep that wall solid with a separate bank account, contracts in the company's name, and a written agreement that notarial fees belong to the LLC.

The limit is your own conduct. An entity does not shield a notary from a claim about the notary's own act. That is what the bond and E&O cover is for.

The S corporation election is a tax choice

An S corporation is not a separate kind of Pennsylvania filing. It is a federal election made on Form 2553 by an LLC or corporation that already exists.

The election changes how profit is taxed. You pay yourself a reasonable salary through payroll, and the remaining profit comes out as distributions. For a busy agent, that can reduce self-employment-style tax on part of the income.

It also adds payroll, withholding and a separate business return. For many signing agents, that overhead costs more than it saves, especially in the first year. Look at it again once profit is steady, and get an accountant's view on the numbers.

One detail is specific to this trade. Notary fees already escape self-employment tax. The election matters mainly for the service-fee part of your income.

Two notaries working together

Two notaries who share work and profit without filing anything may be a general partnership. Each can be personally exposed to business debts the other creates.

Each partner still needs a personal commission. Neither can use the other's stamp. What the partnership shares is the business: the bookings, the office, the marketing and the money.

A multi-member LLC separates the business from both partners. It also makes you write an operating agreement. Put in who owns what share, who can sign contracts, and what happens if one of you stops notarizing. That last point matters here, because a partner whose commission lapses can no longer do the core work.

Pennsylvania LLC owners are called members and may include individuals, corporations or other LLCs. — Pennsylvania Department of State, retrieved 2026-09-27

Pennsylvania income tax on each structure

Pennsylvania taxes pass-through business profit at 3.07% on your personal return. That covers sole proprietors, partnerships, S corporations and LLCs not taxed as corporations.

So for state tax, the LLC versus sole proprietor choice does not change the rate. What changes it is electing corporate tax treatment, which moves the LLC into the corporate tax system instead.

Local taxes sit on top and vary by municipality. Check with your local tax collector before you price your first signings. Then read the annual obligations page for the full yearly list.

Changing structure later

You can start as a sole proprietor and form an LLC later. Budget for the paperwork, because every vendor account must move to the new company.

Signing services, title companies and your bank will need a new W-9, new agreements and new account details. Your commission does not change at all, since it was never the business's.

If you expect to grow, forming early is usually simpler than switching mid-year. The filing order is set out in the setup guide, and the formation services page compares filing it yourself with paying a service.
