How to calculate your New Hampshire income taxes

Understanding your New Hampshire income taxes

New Hampshire is one of the few states that do not impose a state income tax on earned income, making it quite tax-friendly for wage earners.

However, there is a 5% tax on interest and dividends, which can impact certain taxpayers, particularly those with significant investment income. There are no standard deductions or personal exemptions due to the lack of broader income tax.

Calculate your income tax in New Hampshire

1. Work out your total federal income tax
   1. Gross income adjusted
      Gross income − Pre-tax deductions = Gross income adjusted
   2. Federal taxable income
      Gross income adjusted − Federal standard/itemized deductions = Federal taxable income
   3. Federal income tax liability
      Federal taxable income × Federal income tax rate = Federal income tax liability
   4. Federal payroll tax liability
      Gross income × Federal payroll tax rate = Federal payroll tax liability
2. Calculate your total New Hampshire state income tax
   1. New Hampshire state taxable income
      Gross income adjusted − (New Hampshire state itemized deductions + New Hampshire state exemptions) = New Hampshire state taxable income
   2. New Hampshire state income tax liability
      New Hampshire state taxable income × New Hampshire state income tax rate = New Hampshire state income tax liability
3. Add up all the taxes
   Federal income tax liability + Federal payroll tax liability + New Hampshire state income tax liability = Your total income tax liability

State income tax brackets

New Hampshire does tax income from interest and dividends, however. The Interest and Dividends Tax is a flat rate of 5%. The standard exemption for that tax is $2,400 for Single and $4,800 for married persons filing jointly, so taxpayers with income from interest and dividends below that amount do not have to pay any taxes. Additional exemptions of $1,200 are available to residents who are either 65 years or older, blind or disabled and unable to work.

State exemptions

Taxpayers with income from interest and dividends above their total exemption will pay taxes only on the amount that exceeds the exemption. Say, for example, a single filer earns $6,000 in interest annually. They would pay $180 in taxes, because the 5% tax only applies to the $3,600 above their exemption.
