New Hampshire and self-employment income
New Hampshire has no tax on wages or self-employment income. Its Interest and Dividends Tax was repealed outright for tax years beginning on or after 1 January 2025, so a freelancer with no business-tax exposure files nothing with the state.
New Hampshire at a glance, for a one-person business
| Stands in for an income tax | Business Profits Tax at 7.5% and Business Enterprise Tax at 0.55% |
|---|---|
| Where it starts | $109,000 of gross business income (BPT); $298,000 of receipts or enterprise value tax base (BET) |
| Are freelance services taxable? | No sales tax of any kind |
| State licence | None at state level |
| What a sole proprietor files | Nothing below both thresholds; a BPT return above the first |
None of this is income tax, so none of it is in the calculator above. The same five rows for all 9 states without an income tax sets New Hampshire against the rest.
What a New Hampshire freelancer may still owe
- The Business Profits Tax is 7.5% and applies once gross business income exceeds $109,000. Below that there is no return.
- The Business Enterprise Tax is 0.55% and applies once either gross business receipts or the enterprise value tax base — compensation, interest and dividends paid out — exceeds $298,000. A one-person business with no payroll usually meets neither test.
- Both thresholds are re-indexed every two years. The figures above were set for tax periods beginning on or after 1 January 2025 and still stand for 2026.
- New Hampshire has no sales tax, so selling services or goods to in-state clients creates no registration of its own.
New Hampshire business obligations last read against the agency's own pages on 2026-09-09: RSA 77-A:2, Business Profits Tax, RSA 77-E:2, Business Enterprise Tax, RSA ch. 77, repealed. These are outside the calculator; it computes income tax only.
Where the threshold is measured on gross, not profit
A consultant billing $120,000 and keeping $95,000 after expenses is comfortably inside the Business Profits Tax, because the $109,000 test is applied to gross business income rather than to profit. The return is due even though the deduction for the reasonable compensation of the proprietor's own services commonly leaves little or nothing to tax. The Business Enterprise Tax is a separate question with a separate base: at $120,000 of receipts and no payroll, neither of its tests is met. New Hampshire is therefore the state where this calculator understates the paperwork the most — the tax may well be zero, but the filing is not optional.
How the federal part is worked out
Net profit is 1099 income less business expenses (Schedule C). Self-employment tax is 15.3% of 92.35% of that profit — 12.4% Social Security up to $184,500 of combined wages and earnings, 2.9% Medicare on all of it. Half of that tax, the $16,100 standard deduction ($32,200 joint) and the 20% qualified business income deduction come off before the 2026 brackets are applied; the child tax credit and the earned income credit then reduce what is left, and the refundable parts can offset self-employment tax. The methodology page sets out the full sequence and every rule the calculator leaves out.
Quarterly estimated tax deadlines (2026)
If you expect to owe $1,000 or more of federal tax for the year, the IRS expects four estimated payments (Form 1040-ES). Because New Hampshire has no income tax, there is no separate state estimate to make.
The 2026 dates are April 15, 2026, June 15, 2026, September 15, 2026, January 15, 2027. The federal amount is split into four equal Form 1040-ES installments after any withholding you entered; paying 100% of last year's tax instead (110% above $150,000 of prior-year AGI) also avoids the penalty. The quarterly calculator works that out and subtracts what you have already paid, and the guide to the due dates explains the rule.
Common questions
Do I pay self-employment tax if New Hampshire has no income tax?
Yes. Self-employment tax is a federal tax that funds Social Security and Medicare. It applies in every state regardless of state income tax.
Is half of self-employment tax really deductible?
Yes, for federal tax. The employer-equivalent half is an adjustment to income on Schedule 1, which lowers your AGI and therefore your federal income tax. It does not reduce the self-employment tax itself.
Does an LLC change these numbers?
For federal income tax and self-employment tax, a single-member LLC taxed as a sole proprietorship follows exactly the calculation shown here. State and local obligations can still differ: an LLC may be a taxable entity for a state's franchise, gross-receipts or excise tax, and may owe registration or licence fees a sole proprietor does not — New Hampshire's are listed above. Electing S-corporation status changes the federal arithmetic too (salary plus distributions) and is outside this tool's scope.
What if I moved to New Hampshire during the year?
Income earned while you were a resident of another state is taxable there under that state's rules. This calculator assumes all income was earned as a New Hampshire resident.
