When parents share custody, it can be confusing to understand who claims the child on taxes with 50/50 custody, especially because only one parent can receive certain tax benefits. Many parents are surprised to learn that federal tax law does not allow both parents to claim the same child, even when the schedules are equal. These rules matter because they affect important credits like the Child Tax Credit, the Dependent Care Credit, and the Earned Income Tax Credit (EITC).
Hartin Family Law helps you understand these rules in simple terms so you can make choices that protect your rights, reduce stress, and avoid mistakes with the Internal Revenue Service (IRS). Our goal is to help parents build clear co-parenting plans that avoid fights over tax returns and prevent problems that may delay a tax refund or trigger a formal notice from the IRS.
With the right guidance, parents can feel more confident when filing taxes after a divorce decree or custody agreement.
IRS Rules on Claiming a Child
When deciding who can claim a child on taxes in a joint-custody situation, the IRS uses very specific rules under the qualifying-child tests. These rules determine which parent may claim the child as a dependent for tax purposes, and they are based on where the child lived, the amount of physical custody each parent had, and income thresholds.
Because only one taxpayer may claim the same dependent in a tax year, these rules help the IRS avoid conflicts between two parents filing separate returns.
Qualifying Child Requirements
A child must meet several tests to be considered a qualifying child, including age, relationship, residency, and support tests. The child must live with one or both parents for more than half the year, and the child cannot provide more than half of their own personal expenses.
If the child meets these basic rules, then the IRS uses additional steps to determine which parent claims the child on taxes.
Determining the Custodial Parent
Before deciding who receives certain tax benefits, the IRS must determine who is the custodial parent. Even when custody is shared, the IRS defines the custodial parent using clear rules based on the number of nights the child lived with each parent.
This rule is important because the custodial parent is entitled to more tax benefits unless certain rights are transferred through a written agreement.
Who Is the Custodial Parent?
The custodial parent is the parent with whom the child lived for more nights during the tax year. This is true even when divorced parents share physical custody and try to keep the schedule equal. The IRS determines this based on actual overnights, not simply the wording in a custody agreement.
What If the Time Is Truly 50/50?
If the child lived an equal number of nights with both parents, the IRS names the parent with the higher adjusted gross income as the custodial parent. This rule applies when the custody schedule results in true equal custody and no parent has more nights. It ensures that only one parent can claim the child, even when both believe they should be able to.
Who Gets to Claim the Child Tax Benefits?
When two parents share joint custody, different child-related tax benefits may apply. Some benefits can be claimed only by the custodial parent, while others may be transferred to the noncustodial parent if the custodial parent signs the appropriate IRS form. Understanding these rules helps prevent both parents from claiming the same dependent, which can lead to serious tax consequences.
Typical Benefits Involved
- Child Tax Credit (CTC) – Reduces your tax bill for a qualifying child.
- Earned Income Tax Credit (EITC) – Extra credit for working parents with lower taxable income.
- Head of Household status – A special filing status for the custodial parent.
- Child and Dependent Care Credit – Helps cover daycare or childcare costs.
- Tuition and education credits – Can reduce taxes based on school expenses.
Benefits That Only the Custodial Parent May Claim
Some tax benefits can only be used by the custodial parent, and the IRS does not allow these credits to be transferred. The EITC, Head of Household status, and the Dependent Care Credit all depend on where the child lived for more than half the tax year, so only the custodial parent qualifies.
These benefits are tied to physical custody, daily care, and income rules, which is why the IRS limits them to one parent for tax purposes.
Benefits That Can Be Released to the Noncustodial Parent
Certain tax benefits may be given to the noncustodial parent, but only when the custodial parent signs IRS Form 8332. The Child Tax Credit and Additional Child Tax Credit are the main child tax benefits that can be transferred in this way.
When the custodial parent signs Form 8332, the noncustodial parent may claim the child as a dependent for these credits, even in shared custody situations. Without this form, the IRS will not allow the noncustodial parent to claim these tax benefits.
Using IRS Form 8332
Form 8332 helps the IRS determine parent claims when both parents want to share tax benefits. The form must be signed by the custodial parent and attached to the noncustodial parent’s tax returns. Without this form, the IRS will not allow the noncustodial parent to claim the child for tax purposes.
What Is Form 8332?
It is a written agreement that allows the custodial parent to waive their right to claim certain tax benefits in favor of the other parent. It is filed with the noncustodial parent's tax return each tax year it applies.
When Parents Use It
Parents often use Form 8332 when they agree to alternate years for claiming dependents or when the divorce decree assigns tax credits to the noncustodial parent. IRS rules require the form even if the court order states something different.
Revoking or Updating the Form
A custodial parent may revoke or change the agreement by giving written notice to the other parent and filing the updated form with the IRS. This must be done clearly so both parents understand their rights when filing taxes.
IRS Tie-Breaker Rules
When two parents claim the same child on taxes with 50/50 custody, the IRS uses tie-breaker rules. These rules determine which parent may legally claim the dependent when both file separate returns and claim the same child. The Internal Revenue Service automatically applies these steps.
When Both Parents Try to Claim
The IRS uses the following order:
- The parent with whom the child lived for the longest period during the tax year.
- If time is equal, the parent with the higher AGI wins.
- If neither parent qualifies, the IRS selects the qualifying relative with the highest AGI.
Consequences of Wrongly Claiming a Child
If a parent claims a child they are not allowed to claim, the IRS may delay refunds, send a formal notice, remove credits, and even apply penalties. Future child-related tax credits may also be blocked for several years.

The IRS will investigate and apply tie-breaker rules.
Who claims child on taxes with 50/50 custody?
When custody is exactly equal, the IRS uses tiebreaker rules and gives the claim to the parent with the higher adjusted gross income.
Can either parent use the earned income credit?
No, the earned income credit can only be claimed by the custodial parent under IRS regulations.
Can a noncustodial parent claim a dependent child if the parents are legally separated?
A noncustodial parent claims a dependent child only if the custodial parent signs a valid dependency exemption release.
