Calculating Self-Employment Tax

The Guide to Calculating the Self-Employment Tax should be used to understand how to calculate the Self-Employment Payroll Tax.

Tax Rate

The tax rate for self-employment tax is 0.0021 and is applied to annual net earnings from self employment. Net self-employment earnings are generally found on Federal Schedule SE, line 2. The net self-employment earnings on Federal Schedule SE may include earnings reported on Federal Schedule C or C-EZ or Federal Schedule K-1 from Federal Partnership return 1065.  

This is not intended to be tax preparation advice. Please consult your CPA or tax preparer to ensure accurate calculation of annual net earnings.

Reduced Tax Rate for employers with two (2) or less average annual employment

Employers with two (2) or less average annual employees are eligible to claim a reduced tax rate of 0.0015 on the first $100,000 in payroll on both the employer tax and the self-employment tax. See the tax form instructions for how to claim this discounted rate on the 4th quarter return or final return of a closed business that qualifies for the reduced rate.

If a sole proprietor or partnership has no employees, the reduced tax rate is applicable on the first $100,000 of net earnings from self-employment for sole proprietors or each individual partner.
