Sole Proprietor, LLC, or S Corp: Picking a Structure That Fits Your Income

When you start freelancing, your business structure is probably the last thing on your mind. You find clients, do the work and get paid. But as your income grows, the way your business is set up starts to affect how much tax you pay and how much personal risk you carry. Here’s how the three most common options compare.

How each structure is taxed

A sole proprietorship is the default. If you earn money on your own and haven’t registered anything, you’re already one. Your business income goes on Schedule C with your personal return, and you pay income tax plus self-employment tax on your net profit. Self-employment tax is 15.3 percent, covering both the employer and employee shares of Social Security and Medicare.

A single member LLC is taxed the same way by default. The IRS treats it as a “disregarded entity,” so your profit still flows to Schedule C and is still subject to self-employment tax. The difference is legal, not tax-related, at least at first.

An S corp is a tax election, not a separate type of business. An LLC can elect S corp status by filing Form 2553 with the IRS. Once it does, you become an employee of your own company and pay yourself a reasonable salary through payroll. Payroll taxes apply to that salary, but the remaining profit can be taken as distributions that aren’t subject to self-employment tax. For freelancers with steady, healthy profits, that difference can add up to thousands of dollars a year.

S corp status also brings more work: running payroll, filing a separate business return and keeping cleaner books. Understanding S corp taxes before you elect helps you decide whether the savings outweigh the added cost and effort. Many advisors suggest looking at an S corp once your net profit is consistently in the range of $80,000 or more, though the right point depends on your income, state and expenses.

Liability protection and why it matters

Taxes are only half the picture. The other half is what happens if something goes wrong.

As a sole proprietor, there’s no legal line between you and your business. If a client sues you or your business takes on debt it can’t repay, your personal savings, car and even your home could be at risk.

An LLC creates a separate legal entity. In most cases, business debts and lawsuits stay with the business, and your personal assets are protected. That protection holds whether your LLC is taxed as a sole proprietorship or as an S corp. To keep it, though, you need to treat the business as truly separate. Use a dedicated business bank account, sign contracts in the LLC’s name and avoid mixing personal and business spending. Courts can “pierce the veil” when owners blur those lines.

For many freelancers, the path looks like this: start as a sole proprietor, form an LLC once you have regular clients, then elect S corp status as your profits grow.

There’s no single right structure for everyone, and the best choice can change as your business does. Services like Collective help solopreneurs form the right entity and manage the taxes that come with it, so you can spend more time on the work you actually enjoy.
