How the New Hampshire 1099 tax calculator works
New Hampshire has no personal income tax, so a freelancer there pays two federal taxes on net profit, meaning what clients paid minus deductible business expenses: self-employment tax for Social Security and Medicare, and federal income tax. The national 1099 tax calculator shows how each is figured, with the formulas, the 2026 brackets and worked examples at several incomes.
At $100,000 of profit, a single filer owes $14,129.55 of self-employment tax and $8,235.00 of federal income tax, $22,364.55 in all (22.4% of profit). Those amounts are the same in every state without an income tax; the calculator above works them out for your own numbers.
In New Hampshire, business taxes come on top of these federal amounts once gross business income is over $109,000. The next section explains them, and the calculator above includes them.
New Hampshire's business profits and enterprise taxes
New Hampshire doesn't tax wages, but it taxes business income, a sole proprietor's included. A Business Profits Tax return is required when gross business income, meaning receipts before expenses, exceeds $109,000 (for tax periods beginning on or after January 1, 2025). The tax is 7.5% of taxable business profits: for a freelancer, net profit minus a deduction for reasonable compensation for your own work. Up to $75,000 needs no records to show it's reasonable; more is allowed if it's reasonable under federal tax rules (IRC § 162) and you keep records. This estimate caps the deduction at your net profit.
The Business Enterprise Tax is 0.55% of the compensation, interest and dividends a business pays. This estimate uses net earnings from self-employment (Schedule SE: 92.35% of net profit) as the enterprise tax base (RSA 77-E:1, V(c)), whatever deduction you take for the Business Profits Tax. A return is required when gross receipts or that tax base exceed $298,000. The Business Enterprise Tax is credited against the Business Profits Tax, and credit left over carries forward for up to 10 tax periods.
For example, $150,000 of gross income and $100,000 of profit leave $25,000 of taxable business profits after the $75,000 deduction, and $1,875.00 of Business Profits Tax, with no Business Enterprise Tax return required. New Hampshire requires estimates of its business taxes, 25% of each tax due April 15, June 15, September 15 and December 15, once the Business Profits Tax after the credit is over $200 or the Business Enterprise Tax is $260 or more (a date on a weekend or holiday moves to the next business day). Both filing thresholds are adjusted every two years. The calculator assumes taxable income is the same for New Hampshire as for the IRS and a business taxable only in New Hampshire; one also taxable in another state apportions its income. The comparison tables below use profit alone, so they leave these taxes out.

Quarterly estimated taxes for New Hampshire freelancers
With no New Hampshire income tax, your federal quarterly estimated payments go to the IRS on Form 1040-ES, due April 15, June 15 and September 15, 2026, and January 15, 2027. New Hampshire also requires estimates of its business taxes, 25% of each tax due April 15, June 15, September 15 and December 15, once the Business Profits Tax after the credit is over $200 or the Business Enterprise Tax is $260 or more. The "Quarterly payments" view above shows both schedules, and the national page explains the federal safe-harbor rules that avoid an underpayment penalty.
The bottom line
A New Hampshire freelancer's 1099 tax bill is mostly federal: on $100,000 of net profit, self-employment tax is $14,129.55 and federal income tax $8,235.00, and New Hampshire adds no income tax on earned income. All in, that is $22,364.55, or 22.4% of profit.
Set aside about that share of every payment, pay the IRS each quarter, and rerun the New Hampshire 1099 tax calculator when your income changes.
Frequently asked questions
How much should I set aside for taxes as a freelancer in New Hampshire?
A single freelancer in New Hampshire with $75,000 of net profit would owe about $15,494.90 in 2026, or 20.7%; at $100,000 the estimate is $22,364.55 (22.4%). Setting aside a similar share of every payment you receive, and paying it in quarterly installments, keeps you from facing a large bill and underpayment penalties at filing time. Those figures are federal tax. Once gross business income is over $109,000, add New Hampshire's Business Profits Tax: with $150,000 of gross income and $100,000 of profit, it's $1,875.00 after the $75,000 compensation deduction. The calculator above adds it for your numbers.
Does New Hampshire have a state income tax?
No. New Hampshire has no personal income tax. New Hampshire's tax on interest and dividends ended after 2024, so it no longer taxes personal income at all. But its 7.5% Business Profits Tax applies once gross business income exceeds $109,000, and the calculator above includes it.
Do I still pay self-employment tax and estimated tax in New Hampshire?
Yes. Both are federal, so they apply in New Hampshire as in every state: New Hampshire self-employment tax is 15.3% (12.4% for Social Security and 2.9% for Medicare) on 92.35% of net profit, and you pay it with federal income tax through quarterly estimated tax payments due April 15, June 15 and September 15, 2026, and January 15, 2027, so for income tax your New Hampshire estimated tax payments all go to the IRS. New Hampshire also requires estimates of its business taxes, 25% of each tax due April 15, June 15, September 15 and December 15, once the Business Profits Tax after the credit is over $200 or the Business Enterprise Tax is $260 or more. The national 1099 tax calculator explains both.
