How Marriage Affects Your Taxes

Marriage can result in either a “marriage bonus” (tax savings) or “marriage penalty” (higher taxes) depending on:

  • Income disparity between partners
  • Combined income level
  • Current tax brackets and deductions
  • Filing status before marriage

This calculator uses projected 2025 federal tax brackets and standard deduction amounts.
