Frequently Asked Questions
What is the self-employment tax rate?
15.3% total — 12.4% Social Security (up to $168,600 wage base in 2024) + 2.9% Medicare on all net income. You pay both the employer and employee portions.
Can I deduct half of my self-employment tax?
Yes. The IRS lets you deduct 50% of your SE tax from gross income when calculating your AGI. This reduces your federal income tax even if you don't itemize.
Is SE tax different from income tax?
Yes. SE tax covers Social Security and Medicare (FICA). Federal income tax is separate and based on your taxable income after deductions. You owe both as a self-employed person.
Do I have to pay SE tax if I earn under a certain amount?
You owe SE tax if your net self-employment income is $400 or more per year. Below that threshold, no SE tax is due, but you still may owe federal income tax on the income.
How do I reduce my self-employment taxes?
Maximize business expense deductions (home office, mileage, equipment). Contribute to a SEP-IRA or Solo 401k — these reduce taxable income. A tax professional can identify deductions specific to your business.
