Understanding Marriage and Taxes

Filing Jointly: Pros & Cons

  • Pro: Usually lower tax rates for couples with disparate incomes
  • Pro: Higher standard deduction than filing separately
  • Pro: Eligible for more tax credits and deductions
  • Pro: Simplified tax preparation (one return)
  • Con: Joint liability for taxes, penalties, and interest
  • Con: Possible "marriage penalty" if both have high incomes

The Marriage Tax Penalty

A "marriage penalty" occurs when a couple pays more in taxes filing jointly than they would if they were single. This typically affects:

  • Couples where both spouses earn similar high incomes
  • Couples who hit phase-out thresholds for certain tax credits

Filing Separately: Pros & Cons

  • Pro: Protection from joint tax liability
  • Pro: Lower AGI may qualify one spouse for certain deductions
  • Pro: May benefit couples with significant medical expenses
  • Con: Higher tax rates for most income levels
  • Con: Ineligible for many tax credits (e.g. child care credit)
  • Con: Lower deduction and exemption thresholds

The Marriage Tax Bonus

A "marriage bonus" occurs when a married couple pays less in taxes by filing jointly than they would as singles. This typically benefits:

  • Couples with disparate incomes (one high earner, one low/no earner)
  • Couples who can consolidate deductions and credits
