Head of Household Filing Status Explained

1Why this matters

Choosing the right filing status is one of the simplest ways to lower your taxes, and head of household is the status single parents and other caregivers most often miss or misuse. Claiming it when you qualify can save hundreds or thousands of dollars a year; claiming it when you do not can bring an IRS notice and a bill. This guide explains the three tests, who counts as a qualifying person, and what the status is worth.

2What are the three tests?

1. You are unmarried, or considered unmarried, on the last day of the tax year.
2. You paid more than half the cost of keeping up your home for the year.
3. A qualifying person lived with you in that home for more than half the year, except for a dependent parent, who can live elsewhere.

Temporary absences, such as time away at school, in a hospital or in the military, count as time lived with you. The status belongs to the person who maintains the home, not to everyone who shares it.

3Who is a qualifying person?

Usually it is a qualifying child: your son, daughter, stepchild, foster child, sibling or a descendant of one of them, who lived with you for more than half the year and meets the age and support tests. A qualifying child who is married generally must also be your dependent.

A qualifying relative who is your dependent can also be a qualifying person if they are related to you in one of the ways the law lists, such as a parent, grandparent, sibling, aunt, uncle, niece or nephew. Someone who is your dependent only because they lived with you all year, such as a partner or friend, does not make you a head of household, even though you can claim them as a dependent.

If the qualifying person is your dependent parent, the parent does not have to live with you, but you must pay more than half the cost of keeping up the parent's home, including a rest home or nursing home.

4What counts as the cost of keeping up a home?

Rent, mortgage interest, property taxes, home insurance, repairs, utilities and food eaten in the home all count. Clothing, education, medical care, vacations, life insurance and transportation do not, and neither does the value of your own work around the house.

You paid more than half if your share was larger than everyone else's combined, including money from other household members and from public assistance used for household costs. Keep a record of the household's costs and who paid them, especially if other adults live with you.

5When are you considered unmarried?

You are unmarried for this purpose if you were single, divorced or legally separated under a decree on the last day of the year. A married person is considered unmarried if all of these apply:

• You file a separate return.
• You paid more than half the cost of keeping up your home for the year.
• Your spouse did not live in your home during the last six months of the year.
• Your home was the main home of your child, stepchild or foster child for more than half the year, and you can claim the child, or could except that the other parent claims them under a written release.

Only one person can use head of household status for the same home, and only the parent the child lived with for more than half the year can use the child as the qualifying person.

6What is it worth?

The standard deduction for head of household is $24,150 for 2026, against $16,100 for single filers, and $23,625 against $15,750 for 2025. Head of household also has wider tax brackets, so more of your income is taxed at the lowest rates.

Head of household status does not change the income limits for the Earned Income Tax Credit or the Child Tax Credit, which are the same for single and head of household filers, but the lower tax can make those credits go further. See our guides to the EITC and the Child Tax Credit.

7Special situations

Separated and divorced parents

The parent the child lived with for more than half the year can file as head of household, even if they release the child's exemption to the other parent so that parent can claim the Child Tax Credit. The other parent cannot use that child for head of household status.

After a spouse's death

For the two years after the year a spouse dies, a parent with a dependent child at home may be able to file as a qualifying surviving spouse, which uses the joint return's standard deduction and brackets and is usually better than head of household. After that, head of household may apply.

Several adults sharing a home

When adults share costs, add up what each pays. If no one pays more than half, no one in the home can file as head of household, though each may still claim credits they qualify for.

8How to claim it, and how to prove it

You choose head of household by checking that box on Form 1040 and listing the qualifying person. Tax software and paid preparers ask questions about the three tests; paid preparers are required to ask them before claiming the status for you.

If the IRS questions the status, it usually asks you to show that the qualifying person lived with you and that you paid most of the household costs. School or medical records showing the child's address, a lease, and utility and rent receipts are the usual proof, so keep them for at least three years after filing.

9Common mistakes

• Claiming head of household based on a partner or friend who is a dependent but not a relative.
• Both separated parents claiming the status for the same child.
• Claiming it while a spouse still lived in the home during the last six months of the year.
• Not keeping records showing you paid more than half the household's costs.

11What this does not tell you

The tests have exceptions and details, such as for custody and for separated spouses, set out in IRS Publication 501. Your own facts decide the answer.

Standard deduction amounts change every year. The 2026 amounts apply to returns for 2026, and the 2025 amounts to returns for 2025. This guide is not tax advice.
