How Connecticut calculates child support
Connecticut uses the income shares model on net weekly income. The schedule gives one amount for the parents' combined net weekly income and the number of children; each parent owes their share, and the parent the children don't live with pays theirs as current support.
Net income is gross income minus income taxes based on all allowable exemptions, deductions and credits, Social Security and Medicare, CT Paid Leave contributions, health insurance premiums, and a few other listed items. Hourly wages count up to 45 paid hours a week. Connecticut prescribes no tax method, so the net income here is an estimate: the parent the children live with is assumed to file as head of household and claim them.
Connecticut has no parenting-time formula. When parents share physical custody with substantially equal time, the parent with the higher net weekly income pays their own presumptive amount to the other parent; a court may deviate.
If the paying parent's own net weekly income falls in the darker shaded part of the schedule, that amount is their whole obligation and the other parent's income isn't used. The shading protects a self-support reserve of $362 a week (125% of the federal poverty guideline for one person). Below $150 a week there is no obligation.
Health insurance premiums are deducted from the paying parent's income. Child care and unreimbursed medical costs aren't part of the weekly amount: each parent pays a percentage of them as they come up, based on their share of the parents' income after support.
Support and alimony a parent is ordered to pay for another family are deducted from that parent's income. For other children living with a parent, the schedule amount for all of that parent's children on their own income is shared per child, and the part for the other children is deducted.
The schedule ends at $6,000 of combined net weekly income. Above that, courts decide case by case between a minimum, the $6,000 amount, and a maximum, combined income times the percentage at $6,000 (12.61% for one child, 18.27% for two). This estimate shows the minimum.
Weekly amounts are rounded to the nearest dollar. Incomes are rounded to the nearest ten dollars to find the schedule block, and each parent's share is rounded to a whole percentage.
