Filing single vs. head of household
Single and head of household have different:
- Eligibility rules
- Standard deductions
- Tax brackets
The table below compares the key differences:
| Feature | Single | Head of household |
|---|---|---|
| Who qualifies | Unmarried, divorced, or legally separated taxpayers who don’t qualify for another status | Unmarried or considered unmarried who paid more than half the cost of a home for a qualifying person |
| Tax year 2026 standard deduction | $16,100 | $24,150 |
| Tax year 2025 standard deduction | $15,750 | $23,625 |
| Tax brackets | Income reaches each rate sooner | Wider brackets allow more income to be taxed at lower rates |

Note: The amounts shown generally apply to taxpayers under age 65 who aren’t blind. If your eligible expenses exceed the standard deduction, compare the standard deduction vs. itemized deductions before filing.
Who qualifies for head of household
To qualify, you generally must:
- Be unmarried or considered unmarried on the last day of the tax year.
- Pay more than half the cost of keeping up your home.
- Have a qualifying person who meets IRS relationship and residency rules.
A married taxpayer may be considered unmarried if their spouse didn’t live in the home during the last six months of the year and the other IRS requirements are met.
Home costs can include:
- Rent
- Mortgage interest
- Property taxes
- Utilities
- Repairs
- Home insurance
- Food eaten in the home
A qualifying person usually must live with you for more than half the year. However, there is an exception for a dependent parent. If your qualifying person is your parent and you pay more than half the cost to keep up your parent’s main residence, the parent is not required to live with you.
Who should file as single
Single may be the better tax filing status for you if you’re unmarried, divorced, or legally separated and don’t meet every head-of-household requirement. Having a dependent doesn’t automatically qualify you for head of household, although you may still qualify for certain tax credits.
Note: Your filing status can change after:
- Marriage
- Divorce
- Separation
- Another household change.
Rules for divorced or separated parents
Only one parent can use a child to qualify for head of household in a tax year. This is usually the custodial parent, meaning the parent the child lived with for more nights.
Form 8332 may allow the noncustodial parent to claim certain child-related tax benefits, but it doesn’t transfer head-of-household status or the Earned Income Tax Credit. If custody is shared, IRS Publication 501 can provide more clarity.
