Answer
Child support is not taxable income in Connecticut. The receiving parent does not report child support payments as income on federal or Connecticut state tax returns, and the paying parent cannot deduct child support payments. This rule applies to all child support orders regardless of when they were established. Under IRC § 71(c), child support has always been excluded from the tax rules that once applied to alimony, and the Tax Cuts and Jobs Act of 2017 (P.L. 115-97) did not change this treatment. Connecticut follows the federal rule through Conn. Gen. Stat. § 12-701, which uses federal adjusted gross income as the starting point for state income tax.

Federal Tax Treatment of Child Support in Connecticut
Child support payments are completely tax-neutral under federal law. The IRS does not treat child support as taxable income for the parent who receives it, and the parent who pays child support cannot claim a deduction for those payments. This rule has been consistent for decades and was unaffected by the Tax Cuts and Jobs Act of 2017. Connecticut parents should understand that this treatment differs fundamentally from alimony, which had different tax rules prior to 2019.
Under IRC § 71(c), any amount specified as child support in a divorce decree or separation agreement is excluded from the tax treatment that once applied to alimony payments. For divorce agreements executed before January 1, 2019, alimony was deductible by the payor and taxable to the recipient, but child support was always carved out from those rules. For agreements executed after December 31, 2018, the Tax Cuts and Jobs Act eliminated the alimony deduction entirely under Section 11051 of P.L. 115-97, making both child support and alimony non-deductible and non-taxable.
Connecticut state income tax follows the federal treatment automatically. Under Conn. Gen. Stat. § 12-701, Connecticut begins its income tax calculation with federal adjusted gross income. Because child support is not included in federal AGI, it is also excluded from Connecticut taxable income. Connecticut imposes state income tax rates ranging from 2% to 6.99% across seven brackets, but none of those rates apply to child support received.
Is Child Support Taxable in Connecticut for the Receiving Parent?
Child support received is not taxable income in Connecticut under either federal or state tax law. A custodial parent receiving $1,500 per month ($18,000 annually) in child support does not report any of that amount on IRS Form 1040 or Connecticut Form CT-1040. This is true regardless of the amount received, the number of children, or the terms of the divorce decree.
The IRS has maintained this position consistently. Publication 504 (Divorced or Separated Individuals) states that child support payments are not income to the recipient. Connecticut parents should not confuse child support with alimony when preparing tax returns. For pre-2019 divorce agreements, alimony may still be reportable as income, but child support is always excluded. For post-2018 agreements, neither alimony nor child support is reportable income.
This tax treatment creates important financial planning considerations. Because child support is received tax-free, it has greater purchasing power dollar-for-dollar than earned income. A parent receiving $2,000 per month in child support keeps the full $2,000, whereas $2,000 in earned income would be reduced by federal income tax (10-37%), Connecticut state income tax (2-6.99%), and FICA taxes (7.65%). Connecticut parents should factor this tax-free status into their post-divorce budget planning.
Can the Paying Parent Deduct Child Support in Connecticut?
The paying parent cannot deduct child support payments on federal or Connecticut state tax returns. A noncustodial parent paying $2,500 per month ($30,000 annually) in child support receives no tax benefit for those payments. This rule applies to all child support orders entered in Connecticut Superior Court, regardless of the date of the divorce decree.
This non-deductibility distinguishes child support from pre-2019 alimony arrangements. Under older divorce agreements executed before January 1, 2019, alimony payments remain deductible by the payor under the prior version of IRC § 215. However, the child support portion of any combined order was never deductible. Connecticut courts typically specify child support and alimony as separate line items in the dissolution decree, which prevents any ambiguity about which payments qualify for different tax treatment.
Connecticut family courts consider the non-deductibility of child support when calculating support obligations under the Child Support Guidelines (Conn. Agencies Regs. § 46b-215a-1 through § 46b-215a-5c). The guidelines use net income after taxes as the basis for calculating each parent's obligation, which means the tax impact is already built into the support formula. The Connecticut Income Shares Model determines support based on combined parental net weekly income, with each parent responsible for their proportional share.
Child Tax Credit and Claiming Dependents After Divorce in Connecticut
The Child Tax Credit provides $2,000 per qualifying child under age 17, and Connecticut courts routinely allocate this benefit between divorcing parents as part of the dissolution decree. Under IRC § 152(e), the custodial parent — the parent with whom the child lives for the greater number of nights during the calendar year — has the default right to claim the child as a dependent. The noncustodial parent can claim the child only if the custodial parent signs IRS Form 8332.
Connecticut courts have the authority under Conn. Gen. Stat. § 46b-84 to order the custodial parent to execute Form 8332, releasing the dependency claim to the noncustodial parent. Common arrangements in Connecticut divorces include alternating tax years between parents (Parent A claims in odd years, Parent B in even years) or splitting children between parents when multiple children are involved.
What Transfers with Form 8332
- Child Tax Credit ($2,000 per child under 17)
- Credit for Other Dependents ($500 for children 17 and older)
- Dependency exemption (if reinstated after TCJA sunset in 2026)
What Does NOT Transfer with Form 8332
- Head of Household filing status (always remains with custodial parent)
- Earned Income Tax Credit (always remains with custodial parent)
- Child and Dependent Care Credit under IRC § 21 (always remains with custodial parent)
- Exclusion for Dependent Care Benefits under IRC § 129 (stays with custodial parent)
The Connecticut Earned Income Tax Credit, which equals 30.5% of the federal EITC, also remains exclusively with the custodial parent regardless of any Form 8332 release. A custodial parent in Connecticut claiming the federal EITC and the state EITC could receive thousands of dollars in combined credits that cannot be transferred to the noncustodial parent.
TCJA Sunset and Impact on Connecticut Child Support Tax Rules in 2026
The Tax Cuts and Jobs Act provisions are scheduled to sunset after December 31, 2025, which could restore personal exemptions worth approximately $5,000 per dependent for tax year 2026. Connecticut parents with existing divorce decrees should understand how these potential changes affect their tax positions. The child support tax treatment — non-taxable to recipient, non-deductible by payor — will not change regardless of whether TCJA sunsets.
If the personal exemption returns, the dependency claim allocated in Connecticut divorce decrees becomes significantly more valuable. Under the prior law, each dependent exemption reduced taxable income by $4,050 (2017 amount, adjusted for inflation). Combined with the Child Tax Credit, the parent claiming a child could see tax benefits exceeding $3,500 per child. Connecticut courts that previously allocated dependency claims when exemptions were suspended may need to revisit those orders.
The Child Tax Credit itself faces potential changes. If TCJA sunsets without congressional action, the CTC could revert from $2,000 to $1,000 per child, with different refundability rules. Connecticut parents with divorce decrees that specify dollar-value tax benefit splits (rather than dependency claim allocation) should consult a tax professional about potential modification under Conn. Gen. Stat. § 46b-215b, which allows modification upon a substantial change in circumstances.
How Connecticut Calculates Child Support
Connecticut uses the Income Shares Model to calculate child support, determining the basic obligation from a schedule based on combined parental net weekly income and the number of children. For a family with combined net weekly income of $2,000 and two children, the basic support obligation is approximately $471 per week under the current Connecticut Child Support Guidelines. Each parent's share is proportional to their percentage of combined net income.
The calculation follows a specific process under Conn. Gen. Stat. § 46b-215a:
- Determine each parent's net weekly income (gross income minus federal and state taxes, FICA, mandatory retirement contributions, union dues, and existing support orders for other children)
- Combine both parents' net incomes
- Look up the basic child support obligation from the Schedule of Basic Support Obligations
- Allocate each parent's share based on their percentage of combined income
- Add child care costs, health insurance premiums, and unreimbursed medical expenses exceeding $100 per child per year, allocated proportionally
| Combined Net Weekly Income | 1 Child | 2 Children | 3 Children |
|---|---|---|---|
| $1,000 | $195/week | $261/week | $301/week |
| $1,500 | $271/week | $375/week | $436/week |
| $2,000 | $337/week | $471/week | $553/week |
| $2,500 | $393/week | $554/week | $655/week |
| $3,000 | $443/week | $626/week | $743/week |
| $4,000 | $530/week | $755/week | $901/week |
Connecticut applies a low-income adjustment when the noncustodial parent's net income falls below the self-support reserve, which equals 100% of the federal poverty level for a single individual ($15,650 in 2025). The minimum child support order in such cases is $50 per week. A shared physical custody adjustment applies when the noncustodial parent has more than 35% of annual overnights with the child.
Child Support Duration and Educational Support in Connecticut
Child support in Connecticut generally continues until the child reaches age 18, or age 19 if the child is still enrolled full-time in high school, under Conn. Gen. Stat. § 46b-84. Connecticut courts may also order post-majority educational support for college expenses up to age 23 under Conn. Gen. Stat. § 46b-56c. These educational support orders can include tuition, room and board, books, and fees.
The tax treatment of child support does not change when the child reaches majority. If a parent continues making support payments for a child over age 18 who is still in high school, those payments remain non-taxable to the recipient and non-deductible by the payor. Educational support ordered under § 46b-56c may have different characteristics — payments made directly to a college or university are not income to the child, but the tax implications depend on whether the payments qualify as scholarships, gifts, or support.
Connecticut parents should note that the Child Tax Credit requires the child to be under age 17, which means the credit expires before child support obligations end. For children aged 17-19 (or 17-23 with educational support orders), the Credit for Other Dependents provides only $500, compared to the $2,000 CTC for younger children. Tax planning for the final years of child support should account for this reduced benefit.
Modification of Child Support Orders in Connecticut
Connecticut allows modification of child support orders upon a showing of substantial change in circumstances under Conn. Gen. Stat. § 46b-215b. A deviation of 15% or more from the current guidelines amount generally constitutes a substantial change. The Connecticut Department of Social Services (Title IV-D agency) must review support orders every three years upon request of either parent.
Modification does not change the tax treatment of child support. Whether the court increases or decreases the support obligation, the payments remain non-taxable income to the recipient and non-deductible by the payor. However, a significant modification could affect other tax-related provisions in the divorce decree, such as the allocation of dependency claims or the division of tax benefits.
Connecticut courts may modify the dependency claim allocation as part of a support modification. If the paying parent's income increases substantially, the court might reallocate the Child Tax Credit to reflect the changed financial circumstances. The mandatory parenting education program under Conn. Gen. Stat. § 46b-69b is required only at the initial divorce filing, not at modification, though the court retains discretion to order additional education.
Connecticut Residency and Filing Requirements for Divorce
Connecticut requires at least one spouse to have been a resident of the state for a minimum of 12 months before filing for divorce under Conn. Gen. Stat. § 46b-44. The filing fee for a dissolution of marriage in Connecticut Superior Court is $360, which includes a $300 entry fee and a $60 additional fee. As of March 2026, verify current fees with your local Superior Court clerk.
After filing, Connecticut imposes a mandatory 90-day waiting period under Conn. Gen. Stat. § 46b-67 before the court can enter a final decree of dissolution. Uncontested divorces in Connecticut typically conclude within 3 to 5 months from the filing date. Contested divorces involving disputes over child support, custody, or property division can take 1 to 3 years to resolve.
Parents of minor children must complete a mandatory parenting education program within 60 days of the return date, at a cost of approximately $125 per parent. Additional costs include marshal or sheriff service fees of $40 to $75 and certified copy fees of $25 per copy of the divorce decree. Fee waivers are available for indigent parties through the Application for Waiver of Fees (Form JD-FM-75).
Frequently Asked Questions
Is child support taxable in Connecticut?
Child support is not taxable income in Connecticut. The receiving parent does not report child support on federal Form 1040 or Connecticut Form CT-1040. The paying parent cannot deduct child support payments. This rule applies to all Connecticut child support orders regardless of when they were established, under IRC § 71(c) and Conn. Gen. Stat. § 12-701.
Can I claim my child on taxes if I pay child support in Connecticut?
Paying child support does not automatically entitle you to claim the child as a dependent. Under IRC § 152(e), the custodial parent has the default right to claim the dependency. However, Connecticut courts may order the custodial parent to sign IRS Form 8332 releasing the claim to the noncustodial parent, and many Connecticut divorce decrees alternate tax years between parents.
What is the child support tax deduction in Connecticut?
There is no child support tax deduction in Connecticut or under federal law. Child support payments are not deductible by the paying parent on any tax return. This differs from pre-2019 alimony agreements, which may still allow a deduction for alimony payments under the prior version of IRC § 215. Connecticut follows the federal rule through Conn. Gen. Stat. § 12-701.
How does the Child Tax Credit work after divorce in Connecticut?
The Child Tax Credit provides $2,000 per qualifying child under age 17. After divorce, the parent who claims the child as a dependent receives the credit. Connecticut courts typically allocate this benefit through the divorce decree — either alternating years, splitting children between parents, or assigning the credit to the higher-income parent with an offset in support. Form 8332 transfers the credit eligibility.
Does child support count as income for Connecticut state taxes?
Child support does not count as income for Connecticut state tax purposes. Connecticut calculates state income tax starting from federal adjusted gross income under Conn. Gen. Stat. § 12-701. Because child support is excluded from federal AGI, it is automatically excluded from Connecticut taxable income. Connecticut tax rates range from 2% to 6.99%, but none apply to child support received.
What happens to child support tax rules if the TCJA sunsets in 2026?
The child support tax treatment will not change regardless of whether TCJA sunsets. Child support has been non-taxable and non-deductible since well before the Tax Cuts and Jobs Act. However, if personal exemptions return at approximately $5,000 per dependent, the dependency claim allocated in Connecticut divorce decrees becomes significantly more valuable. Parents may seek modification of their orders to reallocate tax benefits under Conn. Gen. Stat. § 46b-215b.
How much is child support in Connecticut for two children?
Connecticut child support for two children depends on combined parental net weekly income under the Income Shares Model. At $2,000 combined net weekly income, the basic obligation is approximately $471 per week. At $3,000 combined, the obligation rises to approximately $626 per week. These amounts come from the Schedule of Basic Support Obligations in Conn. Agencies Regs. § 46b-215a-2c, with add-ons for child care and health insurance.
Can Connecticut courts order who claims the child on taxes?
Yes, Connecticut courts have authority under Conn. Gen. Stat. § 46b-84 to order the custodial parent to execute IRS Form 8332, releasing the dependency claim to the noncustodial parent. Courts consider each parent's income, tax bracket, and the overall financial impact when allocating dependency claims. The order is enforceable through contempt proceedings in Connecticut Superior Court.
Does back child support affect my taxes in Connecticut?
Back child support (arrears) does not directly affect your income tax return because child support is neither taxable nor deductible. However, the Connecticut Department of Social Services can intercept federal and state tax refunds to collect child support arrears through the Federal Tax Refund Offset Program. Arrears exceeding $500 for cases with public assistance or $150 for other cases can trigger a refund intercept.
Is alimony taxable in Connecticut unlike child support?
Alimony tax treatment depends on when the divorce was finalized. For Connecticut divorce decrees entered before January 1, 2019, alimony is deductible by the payor and taxable income to the recipient. For decrees entered after December 31, 2018, alimony is neither deductible nor taxable under Section 11051 of the Tax Cuts and Jobs Act (P.L. 115-97). Child support has never been taxable or deductible regardless of the agreement date.
