Important Notes for Connecticut

  • Connecticut uses the Income Shares model, combining both parents' net weekly incomes to determine the total child support obligation.
  • Net income is calculated by deducting federal and state taxes, Social Security, Medicare, mandatory union dues, and qualified retirement contributions from gross income.
  • Connecticut applies a shared physical custody adjustment when the non-custodial parent has the children for more than 35% of the overnights.
  • The court may deviate from guidelines based on factors such as extraordinary medical expenses, educational expenses, or the child's special needs.

Example Child Support Calculation in Connecticut

Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.

Step 1: Combined monthly income: $5,000 + $3,000 = $8,000

Step 2: Parent A's income share: $5,000 / $8,000 = 62.5%

Step 3: Look up basic obligation from the guidelines schedule for $8,000 combined income and 2 children.

Step 4: Multiply the basic obligation by Parent A's share (62.5%) to determine their payment.

Note: Additional adjustments for health insurance, child care, and parenting time may apply.

Frequently Asked Questions About Connecticut Child Support

How is child support calculated in Connecticut?
Connecticut uses the Income Shares model under CT Gen. Stat. § 46b-215a. Both parents' net incomes are combined, and the basic child support obligation is determined from the guidelines schedule. Each parent pays their proportional share based on their percentage of the combined net income. Adjustments are made for health insurance, child care, and shared custody.
What income is used for Connecticut child support?
Connecticut uses net income, which is gross income minus federal and state income taxes, Social Security, Medicare, mandatory union dues, and qualified retirement contributions. Gross income includes wages, salaries, bonuses, commissions, self-employment income, and other regular income sources.
Does shared custody affect child support in Connecticut?
Yes, Connecticut considers shared physical custody when calculating child support. When the non-custodial parent has the children for more than 35% of overnights (approximately 128 overnights per year), the court may apply a shared custody adjustment that reduces the basic child support obligation.
How long does child support last in Connecticut?
In Connecticut, child support generally continues until the child turns 18. However, if the child is a full-time high school student at age 18, support continues until the child graduates from high school or turns 19, whichever occurs first. The court may also order post-majority support for educational purposes up to age 23.
Can Connecticut child support be modified?
Yes, either parent may file a motion to modify child support if there has been a substantial change in circumstances. Connecticut also permits a modification if the current order deviates from the guidelines by 15% or more. The state recommends reviewing orders every three years.
