New Hampshire self-employment tax, explained
New Hampshire has zero personal income tax as of 2026 — its old tax on interest and dividends (which never applied to wages or business income) was fully repealed effective 2025.
Self-employment (SE) tax is the same everywhere — 15.3% of 92.35% of your net profit, split between Social Security (12.4%, up to the annual wage base) and Medicare (2.9%, uncapped). What changes by state is the income tax layer on top: New Hampshire has no state income tax, applied to your taxable income after federal deductions. For filing status, New Hampshire's tax doesn't apply at all, regardless of filing status, since the state has no personal income tax.

Frequently asked questions
What is the New Hampshire state income tax rate for 1099 income?
New Hampshire has no state income tax. Its tax doesn't apply at all, regardless of filing status, since the state has no personal income tax. See the "New Hampshire self-employment tax, explained" section above for how it applies to your specific numbers.
How is self-employment tax calculated?
Self-employment tax is 15.3% of your net self-employment earnings (92.35% of net profit): 12.4% Social Security up to the annual wage base, plus 2.9% Medicare on all net earnings. If your combined income exceeds the Additional Medicare Tax threshold for your filing status, an extra 0.9% applies above that threshold.
What's the difference between self-employment tax and income tax?
Self-employment tax funds Social Security and Medicare — it's the self-employed equivalent of the payroll taxes an employer would otherwise split with you. Federal (and state) income tax is separate, calculated on your taxable income after deductions like the standard deduction and the QBI deduction.
