Self-employment tax in New Hampshire
New Hampshire does not tax earned income, and its interest-and-dividends tax has been repealed.
New Hampshire charges no individual income tax, so only federal income tax and the 15.3% self-employment tax apply. The federal half never changes: 15.3% on 92.35% of net profit, then income tax on profit less half that SE tax, the standard deduction and up to 20% qualified business income.
The failure mode is cash, not arithmetic. Money lands, it gets spent, and the quarterly due date becomes a crisis. Hate Ledger moves the reserve out of reach the day each deposit clears, so the New Hampshire and federal bills are funded before you see the money.
Frequently asked questions
How much self-employment tax do you pay in New Hampshire?
Self-employment tax is federal: 15.3% on 92.35% of net profit, the same in New Hampshire as everywhere else. New Hampshire charges no individual income tax, so only federal income tax and the 15.3% self-employment tax apply.
What is the total tax rate for self-employed people in New Hampshire?
Most New Hampshire self-employed filers land between 20% and 28% of net profit once federal income tax and the 15.3% SE tax are combined — there is no state income tax to add.
Do I file quarterly estimates in New Hampshire?
Federal estimates are due when you expect to owe $1,000 or more. New Hampshire has no state income tax return for earned income.
Are there local taxes on self-employment income in New Hampshire?
New Hampshire does not add a broad local income tax on self-employment earnings, so state and federal are the two layers to plan for.
Can an S-corp lower self-employment tax in New Hampshire?
It can, once profit is high enough. Payroll tax then applies only to a reasonable salary rather than all profit. New Hampshire state income tax still applies to the full amount, so the savings are federal.
