Frequently Asked Questions

What is self-employment tax?

Self-employment tax is the Social Security and Medicare tax for people who work for themselves. It's 15.3% of your net earnings (12.4% Social Security up to the wage base, plus 2.9% Medicare on all earnings).

Do I have to pay estimated taxes quarterly?

If you expect to owe $1,000 or more in taxes for the year, you're required to make quarterly estimated payments to avoid penalties. This includes both self-employment tax and income tax.

What is the SE tax deduction?

You can deduct half of your self-employment tax when calculating your adjusted gross income. This reduces your income tax liability but does not reduce the SE tax itself.

How do I reduce my self-employment tax?

Consider forming an S-Corporation if your net income exceeds $50,000-$60,000. With an S-Corp, you pay yourself a reasonable salary (subject to payroll taxes) and take remaining profits as distributions (not subject to SE tax).
