How Child Support Is Calculated in Connecticut
Factors That Affect Child Support in Connecticut
Technical details and legal basis
Connecticut uses the Income Shares model (CT Gen. Stat. § 46b-215a) to calculate child support. This model combines both parents' incomes to determine the total obligation, then divides it proportionally based on each parent's share.
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 Calculation
Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.
Step 1: Combined income: $8,000
Step 2: Parent A's share: $5,000 / $8,000 = 62.5%
Step 3: Look up basic obligation for $8,000 combined and 2 children.
Step 4: Multiply by Parent A's share (62.5%).
Adjustments for health insurance, child care, and parenting time may apply.
