Is child support tax deductible in California, and who claims the child on taxes?
Quick answer
No. Under federal tax rules, child support is not deductible by the parent who pays it and is not taxable income to the parent who receives it. To claim the child as a dependent, the IRS looks to the custodial parent, the one the child lived with for more nights during the year, unless that parent signs a release such as Form 8332 for the other parent.

What the law says
IRS Publication 504 (2025): “Child support payments aren’t deductible by the payer and aren’t taxable to the payee.”
Publication 504 also says: “The custodial parent is the parent with whom the child lived for the greater number of nights during the year. The other parent is the noncustodial parent.” If the nights are equal, “the custodial parent is the parent with the higher adjusted gross income.”
The rule for divorced or separated parents is 26 U.S.C. section 152(e). It covers a child who gets over half of their support from parents who are divorced or legally separated, separated under a written agreement, or who lived apart at all times during the last 6 months of the year, and who is in the custody of one or both parents for more than half the year. It lets the noncustodial parent claim the child if “the custodial parent signs a written declaration (in such manner and form as the Secretary may by regulations prescribe) that such custodial parent will not claim such child as a dependent” and the noncustodial parent attaches it to their return; a separate exception covers certain agreements made before 1985. Publication 504 says the custodial parent uses Form 8332 or a similar statement, and that “Form 8332 doesn’t apply to other tax benefits, such as the earned income credit, dependent care credit, or head of household filing status.”
What to do next
If you and the other parent agree to alternate years, the custodial parent signs Form 8332 for the years the other parent claims the child. Publication 504 says that for a divorce decree or separation agreement that went into effect after 2008, a noncustodial parent “can’t attach pages from a divorce decree or separation agreement instead of Form 8332.” This page covers federal rules; for your California return, check with the Franchise Tax Board.
