How to use this calculator

This tool estimates federal and state income taxes for Head-of-Household filers. Enter your annual gross income, select your state, and add common pre-tax deductions (401(k), HSA, IRA) to see an estimated tax liability and take-home pay.

Inputs explained

  • Annual Gross Income: Your total income before taxes and deductions.
  • State: Select the state where you live — state tax rates vary.
  • Dependents: Number of qualifying dependents for the tax year.
  • Pre-tax contributions: Contributions to retirement or HSA reduce taxable income.

Examples

  • Example: $60,000 income, 1 dependent, $3,000 401(k) — shows how pre-tax savings reduce your tax.
  • Try switching the state to see the impact of state income tax differences.

Tips & common mistakes

  • Use annual amounts (not monthly) for income and contributions.
  • Enter pre-tax contributions only if they are taken from payroll before taxes.
  • This calculator estimates taxes — consult a tax professional for filing decisions.

About South Dakota Taxes

No State Income Tax

South Dakota is one of the states that doesn't impose state income tax on wages. This means you only pay federal income tax and FICA (Social Security and Medicare) on your earnings.

However, keep in mind that South Dakota may have other taxes such as sales tax, property tax, or excise taxes to fund state services.
