Self-Employment Tax Estimator

Estimate self-employment tax from net earnings using the adjustment and rate you enter.

Estimated tax

How it works

Net earnings are multiplied by the taxable share you enter, and the rate applies to that base; half of the result is shown because it is commonly deductible.

Example

$80,000 of net earnings at the default share and rate gives a base of $73,880 and about $11,304 of tax.

This tool is for estimation and education, not financial, tax, or legal advice.
