Self-Employed Tax Calculator — New Hampshire (2026)
Self-employed in New Hampshire? Your tax bill has three layers that a W-2 employee never sees in full: 15.3% self-employment tax on 92.35% of net profit, federal income tax, and no New Hampshire income tax at all. This calculator applies all three to your 2026 net profit and shows the quarterly amount you should be setting aside. New Hampshire does not levy a personal state income tax, so the only mandatory withholding on your earnings is federal income tax plus FICA (Social Security and Medicare).

Self-employment tax vs New Hampshire income tax
Self-employment tax is federal and identical in all 50 states: 12.4% Social Security up to $184,500 of net earnings plus 2.9% Medicare with no cap. Half of it is deductible against income tax, which is why the calculator subtracts it before applying brackets.
Because New Hampshire levies no income tax, the same $80,000 of net profit costs about $18,830 in total tax — one of the lighter loads in the country for freelancers.
New Hampshire has no state income tax on wages and no general sales tax — but property taxes are among the highest in the nation.
Deductions that matter for New Hampshire freelancers
Net profit — not gross revenue — drives every number here. Ordinary and necessary business expenses reduce SE tax, federal tax simultaneously: the 2026 standard mileage rate of $0.67/mile, home-office square footage, software, equipment, professional insurance, and the self-employed health insurance deduction.
Retirement plans go further. A SEP-IRA or solo 401(k) reduces income tax (though not SE tax) and is often the largest single deduction available to a profitable manufacturing contractor in Manchester.
Working for yourself in New Hampshire
New Hampshire's economy leans on manufacturing, healthcare, and tech, which shapes the contractor market around Manchester — and your fixed costs. With one-bedroom rent near $1,650, a freelancer needs meaningfully more gross revenue than an employee to reach the same lifestyle, because there is no employer paying half of FICA.
As of 2025, New Hampshire fully repealed its interest & dividends tax — making it a true no-income-tax state for the first time in its history.
Local and payroll taxes New Hampshire adds on top
New Hampshire adds no state-mandated employee payroll deduction beyond FICA, so nothing extra is taken from your gross pay at the state level.
New Hampshire has no state income tax on wages and no general sales tax — but property taxes are among the highest in the nation.
Nobody withholds these for you when you are self-employed in New Hampshire. Local wage taxes, city business licences and gross-receipts style levies are yours to register for and remit alongside your quarterly federal and state estimates.
Working across a state line from New Hampshire
New Hampshire has no income-tax reciprocity agreements, so if you live here and work across a state line you generally file a nonresident return in the work state and claim a credit at home to avoid double taxation.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Manchester resident spending part of the year at a client site in Massachusetts may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your New Hampshire tax bill
New Hampshire charges no general sales tax, homeowners pay an average effective property tax of 1.93% of market value, and the minimum wage in force during 2026 is $7.25 an hour.
No sales tax and no wage income tax; a 8.5% meals and rooms tax applies.
Income tax is only one part of a state's take. New Hampshire recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. With no state income tax, Social Security, pensions, 401(k) and IRA withdrawals are all free of state tax here.
New Hampshire vs Massachusetts on the same salary
On a $90,000 salary, a single filer keeps about $72,145 a year in New Hampshire against roughly $67,645 in Massachusetts — a difference of $4,500, or $375 a month.
Effective combined rates are 19.8% in New Hampshire and 24.8% in Massachusetts. Set that gap against living costs: index 109 here versus 148 there, with property tax at 1.93% and 1.14% respectively.
