About the Marriage Tax Calculator

Compare the tax you would pay as two single filers with the tax you would pay as a married couple to see whether marriage helps or hurts.

  2. Enter the State Tax Rate (%) and choose whether to use Standard Deductions.
  3. Press Calculate Tax Impact.

Formula and method

The calculator applies progressive tax brackets to each single income and to the combined income, then compares the totals. The difference is the marriage bonus or penalty.

When to use the Marriage Tax Calculator

  • Comparing your combined tax before and after marriage.
  • Understanding whether filing jointly or separately is better.
  • Planning finances as a couple.

Common mistakes to avoid

  • Assuming marriage always raises or always lowers your taxes. It depends on both incomes.
