Who Gets to Claim the Child on Taxes: Tie-Breakers and Form 8332

When parents are divorced, separated, or simply live apart, the IRS gives the right to claim the child on taxes to the custodial parent — the one the child spent the greater number of nights with during the year. That parent keeps the claim unless they voluntarily sign it over to the other parent using Form 8332. A court order granting legal custody, or a divorce decree assigning the tax exemption, does not by itself override the IRS night-counting rule.

The Night-Counting Rule for Separated Parents

For tax purposes, “custodial parent” has one meaning: the parent the child physically slept with for more nights of the year.¹ You count each night individually. A night the child spent on vacation with one parent counts for that parent. If the child is away at school or camp, that night is credited to whichever parent would have had the child if they had been home.

Only one parent can claim a given child. Parents cannot agree between themselves to split the tax benefits for the same child across their two returns.¹ With more than one child, the rule is applied to each child separately: if two children spent more nights with different parents, each parent claims the child who lived primarily with them. That is not a split of one child’s benefits; it is the same rule producing two answers.

The Five Tests the Child Must Pass First

Before anyone can claim a child, the child has to meet the five qualifying-child tests. All five must be satisfied. Failing even one disqualifies the child.²

Relationship. The child must be your son, daughter, stepchild, foster child, or a descendant of any of them, such as a grandchild. Siblings, half-siblings, stepsiblings, and their descendants (nieces, nephews) also count.
Age. Under 19 at year-end, or under 24 if a full-time student for at least parts of five calendar months during the year. No age limit if the child is permanently and totally disabled. The child must also be younger than you.³
Residency. The child lived with you for more than half the year — generally at least 183 nights. Temporary absences for school, medical care, or military service still count as time with you.
Support. The child did not provide more than half of their own financial support during the year. Scholarships received by a full-time student don’t count as the child’s own support.
Joint return. The child did not file a joint return with a spouse, unless it was filed only to claim a refund and no tax would be owed on separate returns.

A child who is permanently and totally disabled — meaning a doctor has determined they cannot engage in substantial work activity because of a condition expected to last at least 12 continuous months or result in death — is exempt from both the age test and the student enrollment requirement.³

Tie-Breakers When More Than One Person Qualifies

Sometimes more than one person legitimately meets all five tests for the same child. A common example: a parent and a grandparent share a household with the child. When that happens, the IRS applies these tie-breakers, in this order.²

A parent always wins over a non-parent (grandparent, aunt, uncle, other relative).
If both parents qualify but don’t file jointly, the parent the child lived with for more nights claims the child.
If the child lived with both parents for exactly the same number of nights, the parent with the higher adjusted gross income claims.
If no parent claims the child, the eligible relative with the highest AGI claims, but only if that AGI is higher than any parent who could have claimed the child.

A relative who loses a tie-breaker can still claim the Earned Income Tax Credit without a qualifying child, if they separately meet the EITC’s own rules. The IRS changed its position to permit this, and the change applies to all open tax years.⁴

Giving the Claim to the Other Parent With Form 8332

A custodial parent can voluntarily release the right to claim the child, letting the non-custodial parent take it instead. The release is made on IRS Form 8332 (Release/Revocation of Release of Claim to Exemption for Child by Custodial Parent). Without a signed Form 8332, the non-custodial parent has no basis to claim the child, and the return can be rejected or penalized.⁵

The form requires the child’s full name, the tax year or years covered, the custodial parent’s Social Security number, and the custodial parent’s signature. The release can cover a single year, several named years, or all future years.⁶ The non-custodial parent must attach the signed form, or a copy, to the tax return each year they rely on it.

What Transfers and What Stays With the Custodial Parent

Form 8332 transfers only certain benefits. With a signed release, the non-custodial parent can claim the Child Tax Credit, the Additional Child Tax Credit, and the Credit for Other Dependents for that child.¹

Other benefits stay with the custodial parent regardless of the release. The non-custodial parent cannot claim the Earned Income Tax Credit based on that child, even with a signed Form 8332. Head of Household filing status and the Child and Dependent Care Credit likewise remain with the custodial parent who actually maintained the household.⁷ The two parents cannot rearrange this by private agreement.

Revoking a Release You Already Signed

A custodial parent who previously signed Form 8332 can revoke it using Part III of the same form. The revocation takes effect no earlier than the tax year after the custodial parent gives the non-custodial parent a copy of the revocation, or makes a reasonable effort to do so. Provide the notice in 2025, and the earliest the revocation can apply is 2026.⁶ Attach a copy of the revocation to your return for each year you reclaim the child, and keep proof that you notified the other parent.

When Both Parents Claim the Same Child

If one parent has already e-filed claiming a child, the IRS will electronically reject a second return trying to claim that same child. The second filer must then submit a paper return if they believe they have the rightful claim. The IRS processes both returns and applies the tie-breaker rules to decide who is entitled to the dependency benefits.

The taxpayer whose claim is disallowed may owe additional tax plus a 20% accuracy-related penalty on the resulting underpayment if the IRS finds negligence or disregard of the rules.⁸ A separate 20% penalty can apply to an erroneous claim for refund or credit, calculated on the excessive amount claimed.⁹ Records that show where the child actually lived — school records, medical bills, lease agreements listing your address — help you resolve the dispute quickly if the IRS contacts you.

Older Kids and Other Relatives: The Qualifying Relative Path

A child who no longer meets the qualifying-child tests, most commonly because they’ve aged out and aren’t a full-time student, may still be claimed as a “qualifying relative.” That path gives fewer benefits — no EITC — but it does allow the Credit for Other Dependents.

Four conditions apply. The person cannot be anyone else’s qualifying child. The person must either be related to you in one of the specified ways or live with you for the entire year as a member of your household. Their gross income must be below the annual limit, currently $5,050. And you must provide more than half of their total financial support for the year.¹⁰

The support test flips direction here. For a qualifying child, the child simply cannot have supplied more than half of their own support. For a qualifying relative, you must have supplied more than half of theirs.
