TL;DR
- ✅ Check “Head of household” in Step 1(c) only if you qualify
- ✅ 2026 standard deduction: $24,150 (Single is $16,100)
- ✅ Enter your children in Step 3: $2,200 each under 17, $500 per other dependent
- ✅ Not sure you qualify? Choose Single; you can still file as head of household later
Do you qualify?
On the last day of the tax year you must meet all three tests:
- Unmarried or considered unmarried. Divorced, legally separated, or married but living apart from your spouse for the last six months of the year with a qualifying child at home.
- You paid more than half the cost of keeping up the home. Rent or mortgage, utilities, repairs, property tax, food eaten at home.
- A qualifying person lived with you more than half the year. Usually your child. A dependent parent is the exception: they need not live with you if you pay more than half the cost of their home.
Living alone, or sharing a home with a partner or roommate you do not support, does not qualify. If your child lives with you only on weekends, you probably do not qualify either.
What to enter on the W-4
Step 1(c)
Check “Head of household.” Check it only if you are unmarried and pay more than half the cost of keeping up a home for a qualifying person.
Step 2
Leave blank with one job. With two jobs, both W-4s need Step 2; see our two-jobs guide.
Step 3
Enter $2,200 for each qualifying child under 17 and $500 for each other dependent, then add them together.
Step 4
Usually blank. Use 4(c) if you also have side income or always owe in April.
Step 5
Sign and date.

Open the W-4 Calculator →Head of household vs. Single: what changes
The IRS withholding tables treat the two statuses differently. Head of household assumes a $24,150 standard deduction instead of $16,100 and applies the lower rates over a wider income range, so the same salary has less tax taken out of each paycheck. That is a benefit if you qualify. It is also why checking the box without qualifying leaves you short.
The W-4 box changes withholding only. Your filing status on your return depends on your facts at the end of the year, not what you wrote on the W-4. If you check Single now and later qualify, you can still file as head of household and receive the difference as a larger refund. For the Single-filer version of this form, see the W-4 for single filers.
⚠️ Two parents, one child
Only one parent can claim the child as a dependent and, usually, head of household for that child. Do not enter the same child in Step 3 on both parents’ W-4s. Read W-4 Step 3: claiming dependents and the W-4 after a divorce for how to split this.
Frequently asked questions
Who can check Head of Household on the W-4?
You must be unmarried (or considered unmarried) and have paid more than half the cost of keeping up a home that was the main home of a qualifying person for more than half the year. A qualifying person is usually your child or another relative you can claim as a dependent. A dependent parent does not have to live with you, but you must pay more than half the cost of their home.
How much less tax is withheld with Head of Household than Single?
The Head of Household tables use a $24,150 standard deduction and wider tax brackets for 2026, compared with $16,100 for Single, so less is withheld on the same salary. The exact difference depends on your pay, which the calculator works out for you.
Do I claim my child in Step 3 if I am head of household?
Yes. Head of household and the child tax credit are separate. Checking the head of household box changes the tax tables; Step 3 is where you enter $2,200 per qualifying child under 17 and $500 per other dependent.
What happens if I check Head of Household and do not qualify?
Your withholding will be too low, so you may owe tax in April, and if you file as head of household without qualifying you can face an accuracy penalty on top. Pick Single if you are unsure.
