What taxes to pay if you're self-employed

Here’s the short version: as a self-employed individual, you pay two types of taxes – the self-employment tax and the income tax.

How much is the self-employment tax?

The self-employment tax is a flat 15.3% on your net income. It covers your contribution to Social Security (12.4%) and Medicare (2.9%). You owe self-employment tax, no matter how much money you make.

How to calculate self-employment taxes

You owe taxes on your net income at the federal and the state level (unless your state doesn’t have an income tax). The percentage depends on your net income and filing status. And, it’s progressive, meaning you don’t pay the same percentage on all of your income.

How to calculate your net income

Your net income is the result of your gross profit (how much money you made) minus your business expenses (how much money you spent to run your business).
