What is the new hampshire income tax calculator — federal + state tax?
In short
New Hampshire has no state income tax on wages, so your income tax is just federal income tax plus FICA. On a $75,000 income, a single filer in New Hampshire owes roughly $14,079 in total tax — about $8,341 federal, $0 New Hampshire state tax, and $5,738 FICA — leaving $60,922 take-home (a 18.8% effective rate).
This New Hampshire income tax calculator estimates your total 2024 tax burden. It applies federal income tax brackets, FICA (6.2% Social Security + 1.45% Medicare), and New Hampshire's state income tax (no state income tax on wages), using the standard deduction or your itemized amount. New Hampshire taxes neither wages nor sales; its interest-and-dividends tax was repealed in 2025.
