If you're employed, your employer pays for part of your Social Security and Medicare taxes, but as your own boss, you pay it all. In 2013, the IRS reports the rate is 12.4 percent for Social Security and 2.9 percent for Medicare, making a total of 15.3 percent self-employment tax. Since the IRS requires taxes to be paid at the time the income is earned, you may be subject to a penalty if you do not pay enough by the due date each quarter.
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.
