New Hampshire Tax Calculator

The New Hampshire (NH) Tax Calculator is updated for the 2026/27 tax year. While New Hampshire does not impose a standard state income tax on wages, it does apply an Interest and Dividends (I&D) Tax on investment income above specific thresholds. This calculator estimates your federal income tax, FICA, and Medicare deductions to calculate net take-home pay for New Hampshire residents.

Use this tool to explore your federal obligations and understand how investment income may affect your total tax position if you are subject to the New Hampshire I&D Tax.
