Self-Employment Tax Calculator — free online
When you work for yourself, taxes get confusing fast. There's no employer taking a slice out of each paycheck, so the whole self-employment tax sits on you — and it's easy to underestimate what you'll owe. We added a free tool that works it out for you — Self-Employment Tax Calculator — right in your browser.
What it does
You type in your 1099 self-employment income and it estimates your SECA tax for you. It splits out the Social Security part, the Medicare part, and the deductible half you get to subtract later. So instead of guessing, you get a clear number to plan around.
Nothing leaves your device
The whole thing runs inside your browser. Your income numbers are never uploaded, never saved on a server, and nobody else sees them. Close the tab and there's nothing left behind.
How to use it
- Open Self-Employment Tax Calculator in your browser.
- Enter your self-employment income for the year.
- Read your estimated tax — Social Security, Medicare, and the deductible half.
It's free with no limit. There are more small tools on the Apps page.
