When parents separate or divorce, one of the most common questions is: How much child support will I have to pay or receive? In Connecticut, child support isn’t based solely on which parent has the children more often or who earns more money. Connecticut courts use statewide child support guidelines designed to create a consistent starting point for determining support obligations.
The guidelines consider both parents’ income, the number of children, and certain expenses related to raising them. The court can also consider circumstances that justify departing from the guideline amount. Connecticut’s Child Support and Arrearage Guidelines were substantially updated effective August 1, 2026. The guidelines in effect on the date support is determined generally control the calculation.
Connecticut Child Support Starts With Both Parents’ Income
Connecticut generally uses a combined-income approach. The basic calculation begins by determining each parent’s net weekly income and then combining those amounts.
The child support worksheet also considers items such as:
- Gross income,
- Federal income taxes,
- Social Security or mandatory retirement deductions,
- Medicare taxes,
- State and local income taxes,
- Certain allowable deductions and expenses,
- The number of children involved, and
- Each parent’s percentage share of the combined income.
For example, imagine one parent has $1,500 in net weekly income, and the other has $1,000. Their combined net weekly income is $2,500. The parent earning $1,500 contributes 60% of the combined income, while the other parent contributes 40%. The guideline calculation then allocates the basic support obligation between them.
That does not necessarily mean the parent earning 60% will simply write a check for 60% of every expense. The guideline worksheet and the actual parenting and custody arrangement matter.
What About Health Insurance and Child Care?
Child support is not limited to the basic weekly amount. A Connecticut support order may also address:
- Health insurance for the child,
- Uninsured medical expenses,
- Work-related childcare expenses,
- Childcare contributions,
- Certain extraordinary expenses, and
- Arrearages or past-due support.
Connecticut law specifically provides that the child support guidelines apply to current support, health care coverage, childcare contributions, and past-due support.
Many people mistakenly believe that child support payments are simply a percentage of your income. As you can see, in Connecticut the calculation is more complicated and depends on the entire financial picture.
Parenting Time Can Matter
Parents sometimes assume that having equal or nearly equal parenting time automatically eliminates child support. That is not necessarily the case.
The amount of time each parent spends with the child can affect the support calculation, particularly when the parenting arrangement involves shared or substantially equal physical custody. Other circumstances may also justify a deviation from the presumptive guideline amount.
Importantly, custody and child support are related, but they are separate legal issues. A parent should not stop paying court-ordered support simply because the other parent is interfering with parenting time. Likewise, a parent generally should not withhold parenting time because child support is unpaid. Those issues may require separate court remedies.
Can a Judge Deviate From the Guidelines?
Yes. Connecticut law creates a rebuttable presumption that the guidelines amount is the appropriate support amount. A court may deviate when applying the guidelines would be inequitable or inappropriate under the circumstances, but the court generally must identify the reason for the deviation.
Connecticut legal decisions illustrate how seriously courts take this requirement. In Maturo v. Maturo, 296 Conn. 80 (2010), the Connecticut Supreme Court explained that when the parents’ combined net weekly income exceeds the guideline schedule’s upper limit, the court should apply the principles underlying the guidelines rather than treating the guidelines as irrelevant. The court also emphasized the need for a reasoned approach when determining support.
The Connecticut Supreme Court has also addressed situations involving significant differences in the parents’ incomes and when deviation from the presumptive amount may be appropriate.
What If My Income Changes?
Child support orders can sometimes be modified when circumstances substantially change.
Examples might include:
- A significant change in employment income,
- A substantial change in the child’s needs,
- A major change in parenting arrangements,
- A significant change in health insurance costs, or
- A substantial deviation from the child support guidelines.
Connecticut law provides a rebuttable presumption that a deviation of 15% or more from the guideline amount is substantial for modification purposes, although other requirements apply.
A parent should be careful not to wait months or years to address a changed financial situation. A support order does not automatically change just because someone’s income has changed.
A Practical Example
For example, say a father was earning $120,000 per year when a support order was entered. Two years later, he changes jobs and earns substantially less. At the same time, the mother receives a significant income increase.
In Connecticut, the parents’ existing child support order does not necessarily change automatically. They may need to seek a modification and provide updated financial information so the court can determine whether the existing order still complies with the applicable guidelines and statutory requirements.
Frequently Asked Questions
Does Connecticut child support depend only on the noncustodial parent’s income?
No. Connecticut’s guidelines generally consider both parents’ income. The combined income is used to determine the basic support obligation, and each parent’s percentage share is calculated from that combined income.
Can child support be changed after a divorce?
Yes, in appropriate circumstances. A substantial change in circumstances or a substantial deviation from the guidelines can provide a basis for seeking modification. The parent seeking the change generally must file the appropriate motion and provide evidence supporting the requested modification.
For parents trying to establish or modify child support in Connecticut, having accurate financial information is critical. A Connecticut family law attorney can review the applicable guidelines, parenting arrangement, income information, and other circumstances before a support order is entered or modified.
