Self-employment tax (SE tax) is comprised of Social Security and Medicare tax primarily for individuals who work for themselves. It is similar to the Social Security and Medicare taxes withheld from the wages of employees who receive a Form W-2.
You must pay SE tax and file Schedule SE (Form 1040) if either of the following applies:
The SE tax rules apply no matter how old you are and even if you are already receiving social security or Medicare benefits.
Social security coverage. Social security benefits are available to self-employed persons just as they are to wage earners. Your payments of SE tax contribute to your coverage under the Social Security system. Social Security coverage provides you with retirement benefits, disability benefits, survivor benefits, and hospital insurance (Medicare) benefits. By not reporting all of your self-employment income, you could cause your Social Security benefits to be lower when you retire.
For more information see IRS Publication 334 Tax Guide for Small Business.

Note: Statutory employees report their wages, other income, and allowable expenses on Schedule C, Form 1040. They are not liable for self-employment tax because their employers must treat them as employees for social security tax purposes. By inputting the data on Form W-2, and checking the Statutory Employee box in Box 13, the TaxACT program will automatically transfer the information to Schedule C.
