Which filing status should you use? The five IRS options
Single, married filing jointly, married filing separately, head of household and qualifying surviving spouse — what each means and its 2026 standard deduction.
Sourced from official pages · Updated September 30, 2026💡 Key takeaways
- You choose one of five filing statuses; it sets your standard deduction and bracket table.
- Your marital status on December 31 controls whether you can file jointly.
- Head of household needs a qualifying person and that you paid more than half the household costs.
- Married couples can compare joint and separate results.
The five filing statuses
| Status | Who it is for |
|---|---|
| Single | You are unmarried, divorced or legally separated. |
| Married filing jointly | You are married (or your spouse died during the year) and report both incomes on one return. IRS notes most couples save money this way. |
| Married filing separately | You are married and each spouse files their own return, for example if separate filing lowers your tax. |
| Head of household | You are unmarried and paid more than half the cost of keeping up a home for yourself and a qualifying person. |
| Qualifying surviving spouse | Your spouse died within the past 2 years and you have a dependent child; you use joint-return rates and the largest standard deduction. |
2026 standard deduction by status
| Status | Standard deduction |
|---|---|
| Single | $16,100 |
| Married filing jointly | $32,200 |
| Married filing separately | $16,100 |
| Head of household | $24,150 |
Your status also sets which bracket table applies. See the 2026 federal tax brackets and try the federal income tax calculator.
Things to check before choosing
- Your status is decided by your situation on December 31 of the tax year.
- Head of household has qualifying-person and expense tests — read IRS Publication 501 before claiming it.
- Married couples can compare joint and separate results; the calculator lets you switch status to see the difference.
Head of household in more detail
Head of household usually gives a larger standard deduction and wider brackets than single. IRS conditions include being unmarried (or considered unmarried) at year end, paying more than half the cost of keeping up a home and having a qualifying person live with you for more than half the year (a dependent parent need not live with you). See IRS Publication 501.
Married filing jointly vs separately
Joint filing usually results in a lower tax, and often opens more credits, but both spouses are responsible for the return. Separate filing may make sense in special cases such as protecting yourself from a spouse’s tax problems. Run both cases in the tax calculator.
Life events that change your status
- Marriage or divorce during the year
- Death of a spouse (qualifying surviving spouse rules for two following years with a dependent child)
- Having a child or supporting a relative
🔤 Key terms
| Term | Meaning |
|---|---|
| Qualifying person | A relative who meets the tests for head of household |
| Considered unmarried | A special IRS rule for some separated spouses |
| Qualifying surviving spouse | Status for two years after a spouse’s death with a dependent child |
| Filing threshold | Income level that triggers a filing requirement |
⚠️ Common mistakes to avoid
- Choosing head of household without meeting the qualifying-person test.
- Assuming your status from last year still applies.
- Filing separately without comparing the joint result.
- Missing that a spouse’s death affects the status for the year of death and following years.
