Frequently Asked Questions
What is the self-employment tax rate?
The SE tax rate is 15.3%, consisting of 12.4% for Social Security and 2.9% for Medicare. This is calculated on 92.35% of net self-employment income. You effectively pay both the employee and employer portions of FICA taxes.
Why is SE tax calculated on 92.35% of income?
The 92.35% factor (100% - 7.65%) accounts for the employer-equivalent portion of FICA. As an employee, your employer pays half of FICA. As self-employed, you get an equivalent adjustment by only paying SE tax on 92.35% of net earnings.
Can I deduct self-employment tax?
You can deduct half of your self-employment tax (the employer-equivalent portion) from your gross income on Schedule 1 of Form 1040. This reduces your adjusted gross income (AGI) and your income tax, but not the SE tax itself.
