Who Gets the Child Tax Credit in a Divorce: Form 8332 Rules

In a divorce, the parent who gets to claim the Child Tax Credit is the one the child lived with for the greater number of nights during the tax year. The IRS calls that parent the custodial parent, and the rule applies no matter what your divorce decree says, who pays more child support, or whose health insurance covers the child.¹ The custodial parent can hand the credit to the other parent, but only by signing a specific IRS form. Everything else people argue about on this topic flows from those two facts.

The credit itself is worth up to $2,200 per qualifying child in 2026, and only one parent can claim a given child in a given year.² One quick boundary before going further: the child must be under 17 at the end of the tax year, must have a valid Social Security number issued before the return’s due date, and must not have provided more than half of their own support.³ If the child doesn’t clear those, the question of which parent claims the credit never arises.

How the IRS Decides Who the Custodial Parent Is

Count the nights. The custodial parent is whichever parent the child slept at the home of for more nights during the tax year.¹ A child counts as spending the night with you if they sleep at your home (even if you’re away that night) or sleep somewhere else while in your company, such as on a trip together.

If you and your co-parent separated partway through the year, only the nights after the separation count toward this calculation.¹ Whichever parent had the child for more of those remaining nights is the custodial parent that year.

Nights Away From Home

Nights your child spends away from your home for school, illness, vacation, or detention in a juvenile facility still count as nights with you.⁴ A teenager at boarding school whose permanent address is your house is still, for IRS purposes, living with you on those nights. Parents sometimes assume they’ve lost the night count when school absences would actually tip it back in their favor.

What Happens With a True 50/50 Split

If the child spent the same number of nights with each parent, the credit goes to the parent with the higher adjusted gross income for the year.⁵ There is no negotiation and no way around it. In a normal 365-night year one parent will always have at least 183 nights, but exact ties can happen in a leap year or when the child spent some nights with neither parent.

Why Your Divorce Decree Alone Doesn’t Decide It

Divorce agreements often include language like “the father shall claim Child A in even-numbered years.” That provision binds the two of you to each other. It does not bind the IRS. Federal tax law uses its own rules, and a state court order does not override them.⁶ If the decree says the non-custodial parent claims the child but the custodial parent never signs Form 8332, the IRS will deny the non-custodial parent’s claim.

The non-custodial parent’s remedy at that point is family court, not the IRS. You can file a motion to enforce the decree and compel the other parent to sign the form, but that takes time and money. Many family law attorneys handle this by getting Form 8332 signed at the same time the decree is finalized, rather than hoping the other parent cooperates every April.

Form 8332: How the Custodial Parent Hands Over the Credit

The custodial parent can voluntarily release the Child Tax Credit to the non-custodial parent, and the only way to do it is IRS Form 8332, “Release/Revocation of Release of Claim to Exemption for Child by Custodial Parent.”⁷ A text message, an email, a verbal agreement, or a line in a divorce settlement is not a substitute.

On the form, the custodial parent lists both parents’ names and Social Security numbers, the child’s information, and the tax years being released. You can release a single year, multiple specific years, or every future year.⁷ The non-custodial parent then attaches a copy of the signed form to their own return every year they claim the child.

The Narrow Pre-2009 Decree Exception

One exception exists. If your divorce decree or separation agreement took effect after 1984 but before 2009, the non-custodial parent can attach the relevant pages of the decree instead of Form 8332. The decree has to unconditionally state that the non-custodial parent can claim the child, that the custodial parent will not, and which years are covered.⁷ Any condition attached (such as requiring child support to stay current) disqualifies the decree, and anything executed after 2008 needs a signed Form 8332 regardless.

What the Custodial Parent Still Keeps After Signing

This is where divorced parents misread the trade. Signing Form 8332 only releases the Child Tax Credit, the Additional Child Tax Credit, and the credit for other dependents.⁷ Several other benefits stay with the custodial parent no matter what:

The Earned Income Tax Credit based on that child stays with the custodial parent, even after Form 8332 is signed.
Head of household filing status stays with the custodial parent, because it requires the child to actually live in your home for more than half the year.
The child and dependent care credit stays with the custodial parent, since it’s tied to the cost of caring for the child while you work.

So a custodial parent who releases the Child Tax Credit still gets head of household rates and the larger standard deduction that comes with them, still gets the EITC if they qualify, and still gets the dependent care credit. The non-custodial parent gets the Child Tax Credit and the dependency itself. Knowing exactly what moves and what doesn’t is usually what lets both sides agree to a release in the first place.

Taking a Release Back

A custodial parent who already signed Form 8332 for future years can revoke it. Part III of the same form is where you do it. You list the child and the future years you’re revoking, sign it, and give a copy to the other parent (or make a reasonable effort to).⁷

Timing is strict. A revocation takes effect in the tax year after the year you notify the other parent. Deliver the revocation in 2026 and the earliest year it applies to is 2027; you can’t claw back a year that’s already closed.⁷ Attach a copy of the revocation to your return for each year you reclaim the credit, and keep proof you notified the other parent.

If Both Parents Claim the Same Child

The IRS catches it. When you e-file and the child’s Social Security number has already appeared on another return, the second return is rejected and flagged.⁸ Paper returns may both be accepted at first, but the IRS follows up with a CP87A notice to both parents explaining the conflict and giving each parent the option to amend or stand firm.

If neither parent amends, the IRS opens an audit to figure out who had the better claim. The parent who can prove more nights (or produce a signed Form 8332) wins. The parent who loses pays back the credit with interest.

The Ban for Improper Claims

There’s a real penalty for claiming a child you know you can’t. The IRS can bar you from claiming the Child Tax Credit for two years if the improper claim reflected reckless disregard of the rules, and for ten years if it was fraudulent.⁹ The ban applies in future years even if you’d otherwise qualify. Claiming a child you know doesn’t live with you, especially after already losing an audit over the same child, is the pattern that triggers it.
