New Hampshire State Income Tax Calculator

This authoritative, mobile-first New Hampshire income tax calculator helps residents and investors estimate their state tax on interest and dividend income by year. It clarifies that NH does not tax wages, applies the correct I&D rate for the selected year, and factors in your exemptions.

Data Source and Methodology

Authoritative data: New Hampshire Department of Revenue Administration (DRA), “Taxes at a Glance” and Interest & Dividends Tax guidance. See:

All calculations are strictly based on the formulas and data provided by this source.

The Formula Explained

$$ \text{I\&D Income} = \text{Interest} + \text{Dividends} $$
$$ \text{Taxable I\&D} = \max\left(0, \; \text{I\&D Income} - \text{Exemptions}\right) $$
$$ \text{NH I\&D Tax} = \text{Taxable I\&D} \times r_{\text{year}} $$
$$ \text{Total NH State Income Tax} = \text{NH I\&D Tax} + 0 \cdot \text{Wages} $$
$$ \text{Effective NH Rate} = \frac{\text{Total NH State Income Tax}}{\max(1,\; \text{Wages} + \text{I\&D Income})} $$

Glossary of Variables

  • Tax year: The filing year that sets the applicable NH I&D tax rate r_year (0% for 2025+).
  • Filing status: Your filing category (for exemptions guidance; NH wage tax remains 0%).
  • Wages/salary: Earned income; NH state tax on wages is 0%.
  • Interest: Annual taxable interest income subject to NH I&D rules.
  • Dividends: Annual dividend income subject to NH I&D rules.
  • Exemptions: Total allowed deduction from I&D income per NH rules for the selected year and your circumstances.
  • NH taxable I&D: Interest + Dividends − Exemptions, floored at zero.
  • NH I&D tax: Taxable I&D multiplied by the year’s NH rate.
  • Effective NH rate: Total NH tax divided by total income (wages + I&D).

How It Works: A Step-by-Step Example

Suppose tax year = 2024, filing status = Single, wages = $60,000, interest = $1,500, dividends = $1,200, exemptions = $2,400.

  1. I&D Income = 1,500 + 1,200 = 2,700
  2. Taxable I&D = max(0, 2,700 − 2,400) = 300
  3. r_year (2024) = 3% = 0.03
  4. NH I&D Tax = 300 × 0.03 = $9.00
  5. NH wage tax = 0% × 60,000 = $0
  6. Total NH State Income Tax = 9 + 0 = $9
  7. Effective NH Rate = 9 ÷ (60,000 + 2,700) ≈ 0.0145%
