Sole prop, LLC, partnership, S-Corp: what protects you, and how each is taxed

Why your structure is the first real decision

How your business is set up decides three big things: your legal risk, how you’re taxed, and how banks and clients see you. It also decides which tax return you file and when it’s due. Here’s the plain-English tour.

Sole proprietorship — the default

If you’re doing work and haven’t registered anything with your state, this is already what you are. No paperwork, no fees. Income and expenses go on your personal return (Schedule C, due with your 1040 in April). The catch: there is no legal wall between you and the business. If the business is sued, your house, savings, and truck are all exposed.

LLC — the legal wall

A limited liability company makes the business its own legal entity. Run it correctly and your personal assets sit behind that wall. A surprise for most people: a single-member LLC is taxed exactly like a sole proprietorship by default — same Schedule C, same self-employment tax. The LLC doesn’t lower your taxes on day one; it protects you, adds credibility with banks and commercial clients, and opens the door to better tax options later.

Partnership — two or more owners

A partnership files its own return (Form 1065, due in March) but pays no tax itself. Each owner gets a Schedule K-1 showing their share, which flows to their personal return. If you’re going into business with anyone — even family — get the ownership split in writing from day one.

S-Corp — a tax election, not a company type

An S-Corp is something your LLC or corporation elects to become for tax purposes. It files its own return (Form 1120-S, March) and income flows to you by K-1. The draw: once profits are high enough, an S-Corp can reduce self-employment taxes — you pay yourself a reasonable salary and can take the rest as distributions. It adds payroll and paperwork, so the math has to earn it. Run your numbers in our free calculator.

C-Corp — usually not for small service businesses

A C-Corporation pays its own income tax (Form 1120), and owners are taxed again on dividends. It has its uses — outside investors, certain benefits — but for most small service businesses it means double taxation without the upside.

The honest bottom line

• Just testing the waters, little revenue? Sole proprietorship is fine — for now.
• Making steady money and working on other people’s property? Form the LLC. The protection alone is worth the state fee.
• Profit climbing past roughly $30–40K? Time for the S-Corp conversation.
