Where the money goes
- 92.35% of your profit is subject to self-employment tax. On $80,000 that is $73,880.
- Self-employment tax is 15.3% of that: $11,304 ($9,161 Social Security, $2,143 Medicare).
- Half of it, $5,652, is deductible before income tax.
- Federal income tax on what's left comes to $7,527.
A big reason freelancers set aside 25% to 30% of profit for taxes is this combination of self-employment tax and income tax landing together. This is an estimate. It leaves out the qualified business income deduction, retirement contributions and quarterly payments, and it is not tax advice. See the method.
How the self-employment tax is worked out
Self-employment tax applies to 92.35% of net profit, not the full amount. On $80,000 that base is $73,880. The rate is 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare, so the tax comes to $11,304, split into $9,161 Social Security and $2,143 Medicare.
Half of the self-employment tax, $5,652 here, is deducted before federal income tax is figured. That lowers the income the brackets apply to, and the federal income tax then works out to about $7,527 in this example.
Adding the two gives a total of $18,830 on $80,000 of profit, an effective rate of 23.5%, and take-home pay of $61,170. The take-home pay tool does the same layering for salaried work, and the methodology lists the rates used.
Common questions
How much should a freelancer set aside for taxes?
A common rule is 25% to 30% of net profit. In this example the total tax on $80,000 is 23.5% of profit, which is right in that range once income tax and self-employment tax are both counted.
What is self-employment tax?
It is the freelancer version of FICA. An employee splits Social Security and Medicare with their employer. Working for yourself, you pay both halves, which is 15.3%, though you get to deduct half of it.
Do I pay income tax on top of self-employment tax?
Yes. The two are separate. On $80,000 of profit the self-employment tax is $11,304 and federal income tax adds another $7,527, which is why the combined bill reaches $18,830.
When are self-employment taxes paid?
Most people who owe more than a small amount pay in four quarterly installments across the year rather than once at filing. The IRS due dates fall in April, June, September and the following January. Paying too little through the year can bring a penalty.
