What's my tax filing status (single, married, or other)?

The IRS offers these 5 tax filing statuses:

Single

You should file as Single if you weren’t legally married as of December 31, 2025 or you’re not qualified to use the Head of Household status. ‌

Married Filing Jointly (MFJ)

People who are legally married on December 31, 2025 can choose to file a joint tax return. ‌

Both spouses must agree to file jointly to use this status, and it usually results in the lowest overall tax rate. If you file your return jointly, you can’t amend it after to be filed separately. ‌ Both spouses are fully responsible for the tax on the return.  

Married Filing Separately (MFS)

Taxpayers who are legally married as of December 31, 2025 who don't agree to file a joint tax return or want to file separately for other reasons should use the Married Filing Separately status. Couples who file separately typically get fewer tax benefits. ‌However, there are situations where it’s best, like separated couples who haven't legally dissolved their marriage. 

Head of Household (HoH)

You can file as Head of Household if you’re unmarried and have a qualifying dependent child or relative. If you’re married and have a qualifying dependent, you may qualify to file Head of Household if you meet these conditions.

Qualifying surviving spouse

You may qualify for more than one tax filing status. For example, a single (unmarried) person isn't necessarily restricted to single filing status. They may be able to file as Head of Household or Qualifying surviving spouse, assuming those qualifications are met.

Likewise, someone who was legally married as of December 31, 2025 could file as married jointly, married separately, or Head of Household (again, if they meet the qualifications).

If more than one filing status applies to you, we'll choose the one that gives you the biggest tax break.
