Self Employment Tax Calculator

While employees and employers pay Social Security and Medicare taxes under FICA, self-employed individuals pay it under self-employment tax. Use the calculator down below to see how much you will have to pay in self-employment tax and your income subject to it.

First and foremost, not all of the earnings coming from self-employment is subject to tax. Generally, the business expenses must be subtracted from the gross income to find the income subject to self-employment tax. So you won’t pay a self-employment tax for all of your earnings from self-employment.

In addition to subtracting business expenses from net earnings, there are other ways to figure out income subject to self-employment tax. There is the optional method but not everyone is eligible. Take a look at the Form 1040-SE instructions to see if you’re eligible.

If only a portion of your income is from self-employment or had a loss, you may be eligible for the optional method. The perks of calculating self-employment tax based on the optional method is a larger earned income tax credit and child and dependent care credit. It also gives credit toward Social Security coverage.
