Few post-divorce tax disputes are as common, or as avoidable, as two parents claiming the same child. One parent e-files in January. The other’s return is rejected in February. By March, both are calling their attorneys.
The root of the problem is usually a settlement agreement that says who “gets” the child for tax purposes without addressing how the IRS actually decides. This article explains the federal rules, what Form 8332 does and doesn’t do, and how to draft agreements that hold up.
Wait, Aren’t Dependency Exemptions Gone?
Technically, yes. The personal exemption amount has been $0 since 2018, and the One Big Beautiful Bill Act made that permanent. But the right to claim a child as a dependent still matters a great deal, because it unlocks valuable benefits, most importantly the Child Tax Credit (up to $2,200 per qualifying child under age 17 for 2025, adjusted for inflation in later years) and the $500 credit for other dependents. Education credits for a child’s college costs generally follow the dependency claim, too.
Many decrees still use the old phrase “dependency exemption.” That’s fine as shorthand, but the agreement should make clear it refers to the right to claim the child as a dependent and the related credits.
The Default Rule: The Custodial Parent Claims the Child
For federal tax purposes, the custodial parent is the parent with whom the child lived for the greater number of nights during the year. If the nights are exactly equal, the parent with the higher adjusted gross income is treated as the custodial parent.
Notice what that definition ignores: the custody label in the decree, which parent pays more support, and what the parties agreed. The IRS counts nights. A “primary custodial parent” under the decree may not be the custodial parent for tax purposes in a given year.
How the Noncustodial Parent Can Claim the Child
The custodial parent can release the claim to the noncustodial parent. For this special rule to apply, generally all of the following must be true:
- The parents are divorced or legally separated, separated under a written agreement, or lived apart at all times during the last six months of the year.
- The child was in the custody of one or both parents for more than half the year.
- The parents together provided more than half of the child’s support.
- The custodial parent signs a written declaration releasing the claim, and the noncustodial parent attaches it to his or her return.
That written declaration is Form 8332, Release/Revocation of Release of Claim to Exemption for Child by Custodial Parent, or a statement that conforms to it.
What Form 8332 Transfers, and What It Doesn’t
This is where many clients (and some agreements) go wrong. Releasing the dependency claim doesn’t transfer every child-related tax benefit.
| Tax benefit | Goes to noncustodial parent with Form 8332? |
| Claiming the child as a dependent | Yes |
| Child Tax Credit / Credit for Other Dependents | Yes |
| Education credits for the child’s expenses | Generally yes |
| Head of household filing status | No, stays with the custodial parent |
| Earned Income Tax Credit | No, stays with the custodial parent |
| Child and Dependent Care Credit | No, stays with the custodial parent |
| Dependent care FSA exclusion | No, stays with the custodial parent |
In other words, the custodial parent can sign Form 8332 and still file as head of household and claim the Earned Income Tax Credit for the same child. When agreements try to “give” head of household status or the EITC to the noncustodial parent, the IRS won’t honor it.
Why the Divorce Decree Alone Isn’t Enough
For divorce decrees and separation agreements executed after 2008, the noncustodial parent can’t simply attach pages of the decree to the tax return. The release must be made on Form 8332 or a document that conforms to its substance, and the document’s sole purpose must be to release the claim.
Just as important, the release must be unconditional. The Tax Court has repeatedly disallowed claims based on language like “Father may claim the child as long as he is current on child support.” A conditional release isn’t a valid release for federal tax purposes, even if the parent was fully current.
Revoking a Release
A custodial parent who previously released the claim can revoke it using Part III of Form 8332. The revocation takes effect no earlier than the tax year after the year in which the custodial parent provides (or makes reasonable efforts to provide) written notice to the noncustodial parent. The custodial parent must also attach a copy of the revocation to his or her return.
Revocation is a federal tax tool. It doesn’t change what the parties agreed to in state court, so a parent who revokes in violation of the decree may still face consequences in family court.
What Happens When Both Parents Claim the Child
When two returns claim the same child, the second e-filed return is typically rejected. The second parent may paper-file, and the IRS will eventually apply the tie-breaker rules, which generally favor the custodial parent unless a valid Form 8332 is attached to the noncustodial parent’s return. Expect IRS letters, delayed refunds, possible adjustments, and interest for whoever is wrong.
The IRS doesn’t enforce divorce decrees. If a custodial parent refuses to sign Form 8332 as ordered, the noncustodial parent’s remedy is in family court, not with the IRS.
Drafting Tips for Family Law Attorneys
- Specify the tax years. State exactly which years the noncustodial parent may claim each child, or use alternating years, and address what happens in the year the child ages out of the Child Tax Credit.
- Require delivery of a signed Form 8332. Set a firm deadline (for example, by January 31 of the following year) and specify how it will be delivered.
- Keep conditions out of the release. If the right to claim depends on support being current, enforce that condition through the state court order, not by writing it into the release itself.
- Address all the benefits. Clarify that head of household status, the EITC, and the dependent care credit follow the custodial parent under federal law, so neither party has false expectations.
- Consider multi-year releases carefully. Form 8332 can release the claim for a single year, specified years, or all future years. A signed “all future years” release is powerful and sometimes hard to unwind.
- Plan for changed circumstances. Address what happens if parenting time shifts so the noncustodial parent becomes the custodial parent for tax purposes.
- Recommend a tax projection. The parent with higher income may benefit more, or may lose part of the credit to income phaseouts. A quick analysis can maximize the family’s combined tax benefit.
