When to Consider Filing Separately

Filing separately may be beneficial in these situations:

  • One spouse has significant medical expenses (exceeding 7.5% of AGI)
  • One spouse has significant miscellaneous itemized deductions
  • You want to separate your tax liability from your spouse
  • Income-based student loan repayments would be lower for one spouse
  • One spouse has tax issues (such as back taxes or liens)

Important Notes

There are some trade-offs when filing separately:

  • You may lose certain credits (Earned Income, Education, Child and Dependent Care)
  • If one spouse itemizes, the other must also itemize
  • IRA contribution deduction limits may be lower
  • Capital loss deductions are limited to $1,500 per person (vs. $3,000 joint)
  • Tax brackets for separate filers are generally less favorable than joint filers
