Self-employment tax is a tax consisting of Social Security and Medicare taxes primarily for individuals who work for themselves. It is similar to the Social Security and Medicare taxes withheld from the pay of most wage earners. You figure self-employment tax (SE tax) yourself using Schedule SE (Form 1040). Social Security and Medicare taxes of most wage earners are figured by their employers.
You pay your self-employment tax when you pay the rest of your taxes. Self-employment tax is reported on your Form 1040. You can use Schedule C to figure out your net earnings if you are a sole proprietorship or LLC, or you can use your business tax return to figure your net earnings if you are a S-Corp.
