When you work a regular job, your employer quietly takes out taxes from every paycheck before you even see the money. Freelancing doesn’t work that way. You get the full amount, which feels great — but that doesn’t mean you get to keep all of it.
As a freelancer, you’re on the hook for something called self-employment tax — that’s 15.3% on your net self-employment earnings (up to an annual income cap set by the IRS each year; above that, a lower rate applies). This covers Social Security and Medicare, the stuff that normally gets split between you and an employer. When you work for yourself, you’re both. So you pay both sides.
And that’s before income tax even enters the picture. Self-employment tax is separate from regular income tax — you owe both. One small upside: you can deduct half of your self-employment tax when calculating your income tax, which reduces your overall bill a bit.
Here’s where a lot of new freelancers get wrecked: they don’t realize they’re supposed to be paying throughout the year, not just on April 15th. The IRS calls this estimated taxes, and if you expect to owe $1,000 or more in taxes for the year, you’re generally expected to make payments four times a year — once per quarter. If your freelance income is small enough that you’d owe less than $1,000 total, you may not need to make quarterly payments at all — but it’s worth checking. If you skip required payments and try to settle up at the end of the year, you can face interest and penalties on top of what you owe.
If it’s your first year freelancing and you have no idea what you’ll make, just estimate as best you can. If you estimate too high, the IRS lets you recalculate and adjust for the next quarter. If you estimate too low, try to catch up in the following quarter to minimize any penalty. It’s not a perfect system, but staying roughly on track is way better than getting a giant surprise bill in April.
The main thing to understand: freelance income isn’t free money. Set aside a chunk every time you get paid — many people aim for somewhere around 25–30% just to be safe — and make those quarterly payments if required so you’re not scrambling later.
