Who counts as your dependent?

The tests, the tie-breakers, and divorced parents.

Claiming a dependent can be worth thousands of dollars: the $2,200 Child Tax Credit, head of household status, the Earned Income Tax Credit, the child care credit, and Colorado’s family credits all depend on it. The rules are mechanical, and when two people claim the same person, the IRS applies them strictly.

For 2025 and 2026 returns. Current as of October 11, 2026.

What a dependent is worth

Each benefit has its own extra conditions, but they all start with the same question: is this person your dependent?

BenefitValueWho it needs
Child Tax Credit$2,200 per child, up to $1,700 refundableQualifying child under 17 with a Social Security number
Credit for other dependents$500 eachAny other dependent: older children, parents, children with an ITIN
Head of household statusBigger standard deduction and wider brackets than singleAn unmarried taxpayer paying more than half the cost of a home for a qualifying person
Earned Income Tax CreditUp to $8,231 for 2026A qualifying child who lived with you more than half the year
Child and dependent care creditUp to $3,000 from 2026A child under 13, or a spouse or dependent who can’t care for themselves
Education creditsUp to $2,500 per studentThe student must be you, your spouse or your dependent

Colorado’s child tax credit and child care credit follow the same federal dependents. (See the Child Tax Credit and the child care credit.)

The qualifying child: five tests

A qualifying child has no income limit. Your child can earn $30,000 and still be your dependent, as long as all five tests are met.

1. Relationship

Your son, daughter, stepchild, adopted child or eligible foster child; your brother, sister, half-sibling or step-sibling; or a descendant of any of them, like a grandchild, niece or nephew.

2. Age

Under 19 at the end of the year, or under 24 and a full-time student for at least five months of the year, and younger than you (or your spouse). A child who is permanently and totally disabled qualifies at any age.

3. Residency

Lived with you for more than half the year. Time away at school, in the hospital, in juvenile detention or on military service counts as time at home. A child born or who died during the year counts if your home was their home for the time they were alive.

4. Support

The child didn’t pay for more than half of his or her own support. Note the test: it’s whether the child provided half, not whether you did. Scholarships don’t count as the child’s support.

5. Joint return

The child isn’t filing a joint return with a spouse, unless only to claim a refund of withholding.

And for everyone

A dependent must be a U.S. citizen, national or resident, or a resident of Canada or Mexico. Someone who is a dependent can’t claim dependents of their own.

The qualifying relative: four tests

A person who isn’t anyone’s qualifying child may still be your dependent. This is how people claim aging parents, adult children with little income, and other relatives they support.

1. Not a qualifying child

The person can’t be your qualifying child or anyone else’s.

2. Relationship or household

Either related to you (children, parents, grandparents, siblings, in-laws, aunts, uncles, nieces, nephews, step-relatives), or living with you all year as a member of your household, like a partner. A parent doesn’t have to live with you.

3. Gross income

Under $5,200 for 2025 and $5,300 for 2026. Social Security that isn’t taxable doesn’t count toward this, which is why many retired parents qualify.

4. Support

You paid more than half of the person’s total support for the year: housing, food, medical care, clothing, transportation. Their own Social Security spent on themselves counts as their support, not yours.

When siblings share the cost of a parent

If no one pays more than half but together you do, any one of you who paid more than 10% can claim the parent. The others sign a statement agreeing not to, and the one claiming attaches Form 2120. You can rotate the claim from year to year.

When two people could claim the same child

A child can be the qualifying child of more than one person: two parents living apart, or a parent and a grandparent in the same house. Only one can claim the child for the child-related benefits. If you can’t agree, the IRS uses these tie-breakers:

1

A parent beats a non-parent

If a parent can claim the child, a grandparent or aunt can only claim the child if the parent doesn’t, and only if their AGI is higher than any parent’s.

2

More nights wins

Between two parents who don’t file together, the one the child lived with for more nights during the year.

3

Then higher AGI

If the nights are exactly equal, the parent with the higher adjusted gross income.

4

Non-parents: highest AGI

If no parent can claim the child, the eligible person with the highest AGI.

Divorced and separated parents, and Form 8332

For tax purposes, the custodial parent is the one the child spent more nights with during the year, whatever the custody order says. That parent claims the child. But the custodial parent can release part of the claim to the other parent.

What Form 8332 transfers

The custodial parent signs Form 8332, and the noncustodial parent attaches it. It lets the noncustodial parent claim the child as a dependent for the Child Tax Credit and the credit for other dependents.

What it doesn’t transfer

Head of household status, the Earned Income Tax Credit, and the child care credit stay with the custodial parent no matter what. Splitting them this way is often the best result for the family overall.

The divorce decree isn’t enough

For decrees after 2008, the IRS won’t accept pages of the decree in place of Form 8332, even if the decree says who claims the child. The custodial parent has to sign the form or an equivalent statement. A decree can require the other parent to sign, but enforcing that is a matter for the court, not the IRS.

Changing your mind

A release can cover one year, several years or all future years. The custodial parent can revoke it using Part III of Form 8332, effective the following year, after giving the other parent a copy.

Common situations

The college student

Under 24 and full-time, and time at school counts as living at home, so most college students remain qualifying children. The student shouldn’t claim themselves. Only one return gets the education credit for that student.

The adult child at home

Over 24 and not disabled, a child can only be a qualifying relative: income under $5,300 for 2026 and you pay more than half their support. The $500 credit for other dependents and head of household status can still apply.

A parent in assisted living

A parent doesn’t have to live with you. If the parentIf the parent’s taxable income is under the limitrsquo;s gross income, not counting nontaxable Social Security, is under the limit and you pay more than half the cost of care, the parent can be your dependent, and you may qualify for head of household and deduct medical costs you pay.

A partner who lives with you

An unrelated partner who lived with you all year and meets the income and support tests can be a qualifying relative, but doesn’t make you head of household.

A baby born December 31

Counts as having lived with you all year. Get the Social Security number before filing to claim the full Child Tax Credit.

Both parents claimed the child

The second e-filed return is rejected. The second parent can file on paper, and the IRS will apply the tie-breakers and send letters to both. It’s faster and cheaper to agree first.

Common questions

My son is 20 and in college full-time. Can I still claim him?

Usually, yes. A full-time student under 24 can be your qualifying child, and time at school counts as time living with you, as long as he didn’t pay for more than half of his own support.

My daughter earned $12,000 last year. Does that stop me from claiming her?

Not if she’s your qualifying child, because there’s no income limit for a qualifying child. She can file her own return to get her withholding back, checking the box that someone can claim her.

We have 50/50 custody. Who claims our child?

The parent with more nights in the year. If the nights are exactly equal, the parent with the higher AGI. You can still agree to alternate years using Form 8332, but head of household and the earned income credit stay with the parent who has the child more nights.

Can I claim my mother, who lives in her own apartment?

Yes, if her gross income, not counting nontaxable Social Security, is under $5,300 for 2026 and you pay more than half her total support.

My ex and I both claimed our son. What happens now?

The IRS will apply the tie-breaker rules and send letters asking each of you to prove your claim. The parent who doesn’t qualify will owe back the credits, plus interest. Call us before you respond.

Two households, one child?

Bring us the custody arrangement and last year’s returns. We’ll sort out who claims what before both returns get filed. Taxes can be tough, but the Tax Shop has your back.
