Taxes for freelancers and the self-employed

No employer is withholding anything for you — which means the tax system that felt automatic on a W-2 becomes something you have to run yourself, four times a year. Here's how.

When you're self-employed, you're responsible for two things an employer usually handles quietly in the background: paying income tax throughout the year instead of at one deadline, and covering both halves of Social Security and Medicare tax yourself — the full 15.3% self-employment tax, not just the 7.65% an employee sees on a pay stub.

That combination is why freelancer tax questions cluster around a few themes: how much to set aside, when payments are due, which expenses actually reduce the bill, and what happens if a payment is missed. The guides below walk through each of those in order, starting with the one question almost every new freelancer searches first.

FAQ

Common tax questions

Most freelancers file a Form 1040 with a Schedule C (profit or loss from business) and a Schedule SE (self-employment tax). If you pay a contractor above the current 1099-NEC reporting threshold in a year, you may also need to issue one — see our 1099-NEC vs 1099-K guide for the current figure.
In most states, yes — self-employment income is generally taxable at the state level in addition to federal tax, with rules and rates varying by state. A handful of states have no income tax at all.
A deduction reduces the income you're taxed on. A credit reduces your tax bill directly, dollar for dollar, which generally makes credits more valuable than a deduction of the same size.
Not always, especially with simple, single-income freelance situations. But once you're weighing an LLC, S-Corp election, multiple income streams, or significant deductions, a CPA's fee is often smaller than the mistakes they help you avoid.
If you owe $1,000 or more after withholding and credits, the IRS can charge an underpayment penalty calculated on a quarter-by-quarter basis, even if you pay the full balance by the April filing deadline.
