How to calculate net earnings subject to self-employment tax
The self-employment tax is calculated and reported on Schedule SE. Before completing this schedule you will need to determine your net earnings from self-employment.
Sole proprietors and independent contractors determine their net earnings on Schedule C or C-EZ.
Self-employed farmers use Schedule F.
If you are self-employed as a member of a partnership, you should use information from your Schedule K-1 (Form 1065 or 1065-B) to determine your earnings subject to self-employment tax.
Church employees use the information on their W-2 statement.
Then you report these earnings on Schedule SE to figure your self-employment tax. Schedule SE is filed with your federal income tax return. If you do not have to file a federal income tax, but need to report and pay your self-employment tax, you can use Form 1040-SS to report your earnings. If you are a resident of Puerto Rico, you can file Form 1040-PR instead of Form 1040-SS.
Most taxpayers can use the Short Schedule in Section A of Schedule SE. If any of the following apply, you will need to complete Long Schedule SE in Section B.
