New Hampshire Income Tax Calculator - New Hampshire State Tax Explained

The New Hampshire income tax calculator answers the question most people bring here: New Hampshire does not tax personal wages or salaries, so the state income tax line on earned income is always zero.

• • Confirm New Hampshire has no wage income tax: See that New Hampshire does not impose a state personal income tax on wages, salaries, or most retirement income.
• • Estimate take-home pay: Subtract federal income tax and FICA to see net pay.
• • Check the former Interest and Dividends Tax: Enter interest and dividend income with a pre-2025 tax year to see the small I&D tax that was repealed for 2025 and after.
• • Compare states before moving: Model a sample comparison-state rate to see how much a state income tax would change your net pay.

New Hampshire is one of the states that does not levy a state individual income tax on wages, so this New Hampshire income tax calculator shows no state withholding from your paycheck for income tax purposes.

Once you have confirmed the zero state income tax, the New Hampshire Paycheck Calculator breaks the same pay into per-period take-home amounts after federal withholding.

The math is straightforward because one term is always zero: the New Hampshire state income tax on wages equals 0, so the calculator spends its effort on the federal and payroll layers, an optional Interest and Dividends line, and a comparison-state model.

• Gross pay: Total annual wages before any tax or pre-tax deduction.
• Federal income tax: A simplified estimate using federal brackets after the standard deduction for your filing status.
• FICA: Employee Social Security at 6.2% up to the annual wage base plus Medicare at 1.45% on all wages, with an extra 0.9% above the Medicare threshold.
• NH I&D tax: Former New Hampshire tax on interest and dividend income, applied at 5%/4%/3% for 2022/2023/2024 and 0% for 2025 and later.
• Comparison-state model tax: What a state charging your chosen sample flat rate would take from the same gross pay. This is a model, not a quote for any real state.

Because New Hampshire's own wage rate is fixed at zero, the only moving parts are the federal brackets, FICA, the optional I&D line, and the comparison rate you set.

According to New Hampshire Department of Revenue Administration, the state does not tax personal wages or salaries and repealed the Interest and Dividends Tax for tax year 2025 and after.

Because New Hampshire has no state tax, the federal layer is the main variable, and the Federal Income Tax Calculator gives a fuller view of brackets, deductions, and credits.

Four ideas explain why the wage number is zero and what still applies to your paycheck.

The comparison-state model is the most common point of confusion. It is not a real state's formula; it is a flat-rate illustration you control to see the size of the income-tax difference.

When you read the output, treat the New Hampshire state wage tax as the actual fact and the comparison-state tax as a what-if you set yourself.

Thinking in layers, rather than a single take-home number, makes it easier to see why a no-income-tax state still leaves room for federal withholding.

To see the other side of New Hampshire revenue, the New Hampshire Property Tax Calculator shows how the statewide education property tax affects homeowners where the state income tax does not.

Use a recent pay stub, offer letter, or last year's W-2 for the gross pay figure.

1. 1 Enter gross annual pay: Put your total wages before tax and pre-tax deductions in the gross pay field.
2. 2 Pick your filing status: Choose single, married filing jointly, or head of household to set the federal standard deduction.
3. 3 Add pre-tax deductions: Include traditional 401(k), health insurance, or other pre-tax amounts that lower federal taxable income.
4. 4 Enter interest and dividend income: Add interest and dividend income and choose a tax year to see the former I&D tax before its 2025 repeal.
5. 5 Set a comparison rate: Enter a sample flat state rate, such as 5%, to model what another state would take from the same pay.
6. 6 Read the take-home result: Compare the New Hampshire result with the comparison-state model to see the income-tax difference.

A single filer earning $80,000 with $10,000 of interest and dividends in 2024 has federal tax near $9,353, FICA of $6,120, an NH I&D tax of $300 (3% of $10,000), and a comparison-state model tax of $3,270. In 2025 and after the I&D line drops to $0.

If your starting point is an hourly rate or a monthly figure, the Annual Salary Calculator can turn it into the annual gross this calculator expects.

The estimate is useful because the zero state tax changes how you read every other number.

• • Confirms the zero state tax: You see directly that New Hampshire does not take a state income tax from your wages, removing a common source of confusion.
• • Frames take-home pay: Separating federal tax and FICA from the state line shows exactly what reduces your net pay.
• • Quantifies a move: The comparison model puts a dollar figure on the income-tax difference when weighing New Hampshire against a taxing state.
• • Tracks the I&D repeal: The tax-year selector shows how the former Interest and Dividends Tax falls to zero for 2025 and later.
• • Sets up federal planning: With the state line fixed, you can focus planning on federal brackets, deductions, and withholdings.

The biggest benefit is clarity. Once the New Hampshire state tax is confirmed at zero, this New Hampshire income tax calculator spends the rest of the page on the federal and payroll layer you still control through filing status and pre-tax choices.

For a neighboring flat-rate state example, the Arizona Income Tax Calculator shows what a low state income tax looks like next to New Hampshire's zero.

The formula is simple, but several inputs and limits change the take-home number.

• • This calculator estimates federal income tax with simplified brackets and a flat standard deduction; it is not a filed return or tax software.
• • The comparison-state model uses a flat rate you choose and does not reflect any real state's brackets, credits, or deductions.
• • New Hampshire property, business, and other taxes are not included, so the result is not a total New Hampshire tax bill.

High earners should note the Additional Medicare Tax of 0.9% above the income threshold, which slightly lowers take-home pay for very high incomes.

Because New Hampshire has no state income tax on wages, itemized deductions that matter in other states have no state-income-tax effect here, though they can still affect federal tax.

According to Internal Revenue Service, the employee Social Security tax rate is 6.2% and the Medicare rate is 1.45%, for a combined 7.65% FICA rate up to the Social Security wage base, with an additional 0.9% Medicare tax above the income threshold.

According to New Hampshire Department of Revenue Administration, New Hampshire instead relies on business taxes such as the Business Profits Tax and Business Enterprise Tax rather than a personal income tax.

Because New Hampshire's revenue leans on business taxes rather than wages, the Payroll Tax Calculator explains how payroll taxes like FICA work alongside that model.
