Child support is not deductible on your federal tax return, and payments you receive are not taxable income
The IRS treats child support differently from alimony. If you pay child support, you cannot deduct those payments from your income. If you receive child support, you do not report it as income on your Form 1040 or any other federal tax form. This rule applies regardless of whether the payments are court-ordered, part of a divorce decree, or made through a state child support agency.
The distinction matters because alimony (also called spousal support) has different tax treatment — payments made after 2018 are not deductible by the payer and not taxable to the recipient, but the rules changed from earlier years. Child support has remained consistent: it carries no tax consequence for either party.
State tax treatment can differ. A small number of states have their own rules about child support and state income tax, so if you live outside the most common states, you may want to check your state's tax agency website or speak with a tax preparer familiar with your state's code.
Key Takeaways
- Child support payments you make are not deductible on your federal tax return, even if they are court-ordered.
- Child support payments you receive are not reported as income on your federal tax return.
- This rule applies to all child support, whether paid through a state agency, directly to the other parent, or as part of a divorce settlement.
- Alimony (spousal support) has different tax rules and should not be confused with child support on your return.
- A few states may have their own rules, so check your state's tax guidance if you live outside the most common states.
Why the IRS does not tax child support
The IRS classifies child support as a transfer of money for the benefit of the child, not as income or a deductible expense. Because the money is intended to cover the child's living expenses — food, housing, education, healthcare — rather than to replace lost income or compensate for services, it falls outside the categories the tax code taxes or allows as deductions.
This treatment has been consistent since the modern tax code took shape. The payer does not get a deduction because the payment is not considered a business or investment expense. The recipient does not report it as income because it is not compensation for work or a return on investment — it is support for a dependent.
How to report your income if you receive child support
If you receive child support, do not list it anywhere on your federal tax return. It does not go on your Form 1040, Schedule 1, or any other IRS form. When you calculate your adjusted gross income (AGI), child support is not included.
You may still claim the child as a dependent or claim the Child Tax Credit or Child and Dependent Care Credit if you meet the other requirements for those credits — having custody, providing more than half the child's support, and meeting income limits. Child support payments you receive count toward the "more than half support" test, so receiving child support can actually help you meet the threshold for claiming the child.
If a state tax form asks about child support, follow your state's instructions. Most states follow federal rules, but some have separate lines or questions. Your state tax agency website will clarify whether child support should be reported on your state return.
How to report your expenses if you pay child support
If you pay child support, you cannot deduct it on your federal tax return. Do not list it on Schedule 1, Schedule C, or any other form. The IRS does not allow a deduction for child support under any circumstance, even if the payments are very large or court-ordered.
This is different from alimony paid after 2018, which also is not deductible — but it is the same as alimony paid before 2019, which was deductible. If you are paying both child support and alimony, make sure you know which is which, because the tax treatment differs depending on when the divorce or support order was finalized.
You may still claim the child as a dependent if you have custody and meet the support test, but the child support you pay does not reduce your taxable income. Your tax liability is calculated on your full income, minus other deductions and credits you are may have access to to claim.
Distinguishing child support from alimony on your tax return
Child support and alimony are often confused because they both involve payments between former spouses or partners. The tax code treats them very differently, so it is important to know which one you are paying or receiving.
Child support is money paid for the benefit of a child. It covers the child's food, housing, education, healthcare, and other living expenses. Child support is never deductible by the payer and never taxable to the recipient.
Alimony (also called spousal support, maintenance, or spousal maintenance) is money paid to a former spouse for their own living expenses. For divorces finalized after December 31, 2018, alimony is not deductible by the payer and not taxable to the recipient — the same as child support. For divorces finalized before January 1, 2019, alimony is deductible by the payer and taxable to the recipient.
Your divorce decree or support order should clearly label each payment as child support or alimony. If it does not, or if the language is unclear, the IRS looks at whether the payment is contingent on the child's status — for example, if it ends when the child turns 18 or graduates high school, it is child support. If it continues regardless of the child's circumstances, it is likely alimony.
What to do if your divorce decree combines child support and alimony
Some divorce decrees combine child support and alimony into a single payment amount. If yours does, you and the other party need to determine how much of each payment is allocated to child support and how much to alimony, because the tax treatment is different.
If the decree does not specify the split, you can agree on an allocation in writing and both keep a copy. The IRS will accept a reasonable allocation if both parties agree. If you cannot agree, the IRS will look at the decree language and the circumstances — such as whether the payment ends when the child reaches adulthood — to determine the split.
For divorces finalized after 2018, the distinction matters less for federal taxes because both child support and alimony are treated the same way. But for divorces finalized before 2019, getting the allocation right is critical, because alimony is deductible and child support is not.
State tax rules for child support
Most states follow the federal rule: child support is not deductible and not taxable. However, a handful of states have different rules or ask for child support to be reported on the state return for administrative purposes.
If you live in a state with an income tax, check your state's tax agency website or your state's tax form instructions to see whether child support is mentioned. States that do ask for child support information usually want it for record-keeping, not because it changes your tax calculation, but it is worth confirming.
If you are paying or receiving child support across state lines — for example, you live in one state and the other parent lives in another — follow the rules of the state where you file your tax return. Your state's tax agency can clarify if there are any special rules for interstate child support.
Frequently Asked Questions
Can I deduct child support if I pay a lot of it?
No. The IRS does not allow a deduction for child support under any circumstance, regardless of the amount. Even if you pay thousands of dollars per month in court-ordered child support, none of it is deductible on your federal tax return. The same rule applies to all payers.
Do I have to report child support I receive to the IRS?
No. Child support you receive is not reported anywhere on your federal tax return. It does not go on your Form 1040 or any schedule. However, you may still claim the child as a dependent or claim child-related tax credits if you meet the other requirements.
What if my child support order says the payment is for both the child and the other parent?
If the order combines child support and alimony into one payment, you need to allocate how much is for each. For divorces after 2018, both are treated the same way on federal taxes, so the split matters less. For divorces before 2019, the split matters because alimony is deductible and child support is not. Agree on an allocation in writing with the other party.
Does child support affect my may be able to access for tax credits?
Child support you receive does not reduce your income for tax purposes, so it does not affect your may be able to access for credits based on income limits. However, child support counts toward the "more than half support" test for claiming a child as a dependent, which can help you meet the requirements for the Child Tax Credit and other child-related credits.
What if I pay child support but also claim the child as a dependent?
You can do both. Paying child support does not prevent you from claiming the child as a dependent if you meet the other requirements — you have custody and provide more than half the child's support. The child support you pay counts toward the support test. You still cannot deduct the child support itself, but you can claim the dependent exemption and related credits.
