If you are raising kids on your own and filing taxes as “single,” there is a strong chance you are leaving money on the table. Head of household is a separate filing status built for people in your exact situation, and it comes with a bigger standard deduction and wider tax brackets than filing single.
This is general information, not financial or legal advice. Rules change and vary by state. Check the linked official source or talk to a qualified professional.
What head of household gets you in 2026
Two things, and both are large.
A bigger standard deduction. For tax year 2026, the standard deduction is $24,150 for head of household filers versus $16,100 for single filers, per the IRS inflation adjustments for 2026 (Revenue Procedure 2025-32). That is $8,050 more income the IRS never taxes, just for checking the correct box.
Wider tax brackets. Head of household brackets are more generous than single brackets, so more of your income gets taxed at the lower rates. The exact bracket lines for 2026 are in the same IRS revenue procedure.
Together, those two shifts can change your refund by hundreds of dollars, and they stack on top of the credits covered in our plain-English guide to the 2026 EITC and Child Tax Credit.
The three tests, in plain English
You may qualify for head of household if all three of these are true for the tax year, per the IRS filing status rules and Publication 501:
- You were unmarried, or “considered unmarried,” on December 31. Divorced and never-married moms pass this test automatically. Separated moms should read the next section closely.
- You paid more than half the cost of keeping up your home for the year. Half is the exact line. 50/50 does not pass; 51/49 does.
- A qualifying person lived with you more than half the year. For most readers here, that is your child. Temporary absences like school, camp, or a hospital stay still count as time living with you.
Separated but not divorced yet? The “considered unmarried” rule
You do not have to wait for a divorce decree. The IRS treats you as unmarried for head of household purposes if all of these are true:
- You file a separate return from your spouse.
- Your spouse did not live in your home at any time during the last six months of the tax year.
- Your home was your child’s main home for more than half the year.
- You paid more than half the cost of keeping up that home.
- You can claim the child as a dependent, or could except that the other parent claims them under the rules for separated parents.
The full test is in IRS Publication 504 for divorced or separated individuals. If your split happened in the second half of the year, mark your calendar: the six-month clock matters for next year’s return.
What counts as “keeping up a home”
This is where most moms need a pencil and ten minutes. The IRS counts specific costs, and only those:
| Counts | Does not count |
|---|---|
| Rent or mortgage interest | Clothing |
| Property taxes and home insurance | Education costs |
| Utilities | Medical bills |
| Repairs and maintenance | Vacations |
| Food eaten in the home | Life insurance and transportation |
Add up the counting column for the whole year, then ask: did I pay more than half of that total? Money you earned and savings you spent count as you paying. Child support you received is a gray area the IRS does not squarely address; many tax professionals treat it as paid by the other parent, so run Worksheet 1 in Publication 501 or ask a VITA volunteer before counting it. Money someone else paid directly, like a relative covering the electric bill or an ex paying the mortgage on a house you live in, counts against your half. The worksheet in Publication 501 walks the math line by line.
How to check your status in about ten minutes
The IRS has a free interactive tool that asks the questions in order and hands you the answer: What is my filing status? on irs.gov. Have three things in mind before you start: your marital situation on December 31, roughly what you spent on the home, and how many nights your child slept under your roof. Free tax preparers through the IRS VITA program can also make the call for you at filing time, at no cost, if your income qualifies.
The three mistakes that trip people up
Splitting the house 50/50 with a roommate or relative. If you and your sister each pay exactly half of everything, neither of you passes the more-than-half test. Track who pays what; a small shift in who covers groceries can change the answer.
Assuming the parent who claims the child is automatically head of household. The dependency claim and the filing status are separate tests. A signed IRS form can send the Child Tax Credit to the other parent while head of household stays with you, because your home is where the child lived more than half the year. The rules for separated parents are laid out on the IRS Child Tax Credit page.
Both parents claiming head of household for the same child. Only one household can be the child’s main home for more than half the year. If your co-parent files first and wrongly, your correct return can still be filed on paper, and IRS tiebreaker rules settle it. Keep a simple record of overnights if your custody schedule is close to even.
FAQ: head of household in 2026
Can I file head of household with no income tax withheld or very low income?
Yes, and it often pays to file even when you are under the filing requirement. Refundable credits like the EITC arrive only if you file, and filing status affects the size of those credits. See our 2026 tax credits guide for the numbers.
Does child support I receive count as income for these tests?
Child support is not taxable income to you. For the keeping-up-a-home test, the IRS does not clearly say whether support you receive counts as money you paid, and many tax professionals treat it as paid by the other parent; check Worksheet 1 in Publication 501 or ask a VITA volunteer. What it never does is count as earned income for credit purposes.
My child turned 18 this year. Do I still qualify?
Possibly. A qualifying child generally must be under 19 at year end, or under 24 and a full-time student, and must have lived with you more than half the year. Publication 501 has the dependent tests in full.
Can two single moms sharing an apartment both file head of household?
Sometimes, yes. If each mom pays more than half the cost of her own separate household within the shared home, and each has her own qualifying child, the IRS can treat the arrangement as two households. Documentation matters here, and this is a case where a VITA volunteer earns their keep.

Run the IRS filing status tool this week, then put the answer to work: the bigger refund belongs in the one-income budget system, and tax season is the natural moment to run the state-by-state benefits check, since the same income numbers answer both questions.
