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.
The return must include a Schedule SE, which you use to calculate how much self-employment tax you owe. However, when you are filling out your 1040, the IRS allows you to deduct a portion of the self-employment tax payments you make as an adjustment to income. You can deduct between 50 and approximately 57 percent of your self-employment tax payments. The precise amount depends on how much self-employment income you earn.
