With a progressive income tax system ranging from 0% to 6.6%, Delaware requires accurate calculations to avoid underpaying or overpaying. This calculator makes it easy for employees, retirees, and freelancers to get clarity on their net earnings.

How the Calculator Works

This Delaware income tax estimator uses your gross annual income and applies the 2025 Delaware tax brackets, exemptions, and credits to determine your estimated state tax. It also adjusts your taxable income based on personal factors like filing status, age (especially for those 60+), and number of dependents.

Input Fields Explained

  • Gross Income ($): Enter your total income before any taxes or deductions. This includes wages, salaries, tips, or self-employment earnings.
  • Filing Status: Choose between “Single,” “Married Filing Jointly,” or “Head of Household.” This affects your standard deduction and tax bracket.
  • Age: Your age helps determine eligibility for age-based exclusions (e.g., retirement income for those 60+).
  • Number of Dependents: Reduces taxable income through exemptions, lowering your tax liability. If you’re paid monthly, use the Texas monthly calculator to review take-home pay.

Calculation Formula (Plain Text)

Here’s a simplified version of how the calculator estimates your Delaware state tax:

1. Adjusted Gross Income (AGI) = Gross Income
2. Exemptions = (Personal Exemption + Dependent Exemptions + Age Exemptions)
3. Taxable Income = AGI - Exemptions
4. State Income Tax = Apply Delaware tax brackets to Taxable Income

Delaware’s 2025 income tax brackets are progressive and include:

  • 0% on the first $2,000
  • 2.2% on income from $2,001 to $5,000
  • 3.9% from $5,001 to $10,000
  • 4.8% from $10,001 to $20,000
  • 5.2% from $20,001 to $25,000
  • 5.55% from $25,001 to $60,000
  • 6.6% on income above $60,000
