What is the Self-Employment Tax?
Self-Employment Tax is the tax towards Social Security and Medicare, required to be paid by a self-employed individual person (i.e. sole proprietors, contractors and freelancers) who has net earnings of $400 or more for the concerned tax period towards the federal government and such tax is reported through the file of Form 1040 Schedule SE.
Self-Employment Tax Rate
The Self-employment tax has two components – Social Security Tax & the Medicare Tax. The basic tax structure is 12.4% for Social Security Tax & 2.9% for Medicare Tax, making it a total of 12.4+2.9= 15.3%
The Social Security tax also has two components – The employer pays social security tax of 6.2% & the employee pays social security tax of 6.2%. Thus, the self-employed person is required to pay for both rates. This makes the total social security tax rate as 12.4%.
The breakup of the self-employment tax is available with the following table:
However, not the whole of net earnings is liable for the 15.3% self-employment tax rate. The first $ 137,700 is liable for social security tax only. Amount beyond $ 137,700 is liable for both social security tax as well as Medicare tax.

However, you are required to pay 0.90% for Additional Medicare in case the total earnings exceed $200,000 (in case of single filer) or exceed $250,000 (in case of joint filer).
In case additional Medicare tax is considered, the total Medicare tax becomes 2.9 + 0.9 = 3.8% in some instance. In that the employment tax reaches 15.30+0.90= 16.20%
