How New Hampshire state income tax works

New Hampshire is one of the nine states with no personal income tax. Your paycheck and 401(k) contributions are subject only to federal income tax and FICA - there is no state income tax withheld, which is why New Hampshire residents keep more of every paycheck than workers in most other states. No tax on wages or retirement income (the interest/dividends tax was repealed for 2025).

Assumptions & notes

How is take-home estimated?

We subtract your 401(k) deferral and the standard deduction from salary, apply the 2026 federal income-tax brackets for your filing status, subtract FICA (7.65%), and - if you pick a state - add 2025 state income tax. It's an estimate: local/city taxes, credits and state retirement-income exclusions aren't modeled, so your real paycheck may differ.

Why does saving more cost less than it seems?

Traditional 401(k) contributions come out before income tax. If you're in the 22% bracket, a $100 contribution only reduces take-home by about $78 - the other $22 was tax you'd have paid anyway.

How accurate is the state tax?

We apply each state's published income-tax brackets and standard deduction. See our methodology for sources and the states still pending verification. Always confirm with your state's Department of Revenue.
