Frequently Asked Questions
How is SE tax calculated?▾
Self-employment tax is 15.3% on 92.35% of net income: 12.4% Social Security (up to $176,100) + 2.9% Medicare (all income) + 0.9% additional Medicare above $200K.
Can I deduct SE tax?▾
Yes. You can deduct the employer-equivalent half when calculating adjusted gross income. This reduces income tax but not SE tax.
When are quarterly payments due?▾
April 15, June 15, September 15, and January 15 of the following year.
