Self-Employment Tax Calculator

When you are self-employed, you must pay both the employer and the employee portions of social contributions, which often totals around 15.3% of your net business profit.

This tax generally applies to your net earnings from self-employment. This is your gross business income minus all ordinary and necessary business expenses and deductions.

In many tax systems, you are allowed to deduct the "employer" half of the self-employment tax from your gross income when calculating your final personal income tax liability.
