How Connecticut Calculates Child Support

Child support in Connecticut isn’t determined by negotiation alone or by what seems fair to the parents involved. The state uses a formula-based approach grounded in income shares principles, and understanding how that formula works helps parents anticipate what an order is likely to look like and what can be done when standard guidelines don’t fit a family’s actual situation.

The Income Shares Model

Connecticut uses an income shares model to calculate child support. The premise is that a child should receive the same proportion of parental income they would have received if the household remained intact. Rather than looking only at the paying parent’s income, the model considers both parents’ incomes and combines them to establish what the child’s total financial support should be.

Connecticut’s Child Support Guidelines establish support amounts tied to the combined net income of both parents and the number of children. The proportional share each parent owes is then calculated based on what percentage of the combined income each parent contributes.

What Goes Into the Calculation

The calculation relies on several core figures:

• Net weekly income for each parent, which accounts for income taxes, Social Security, Medicare, and certain other deductions from gross income
• The number of children requiring support
• Health insurance costs for the children, which are factored into the total obligation
• Child care expenses related to employment or education for the custodial parent

Parents are expected to disclose income from all sources, including wages, self-employment income, rental income, and investment returns. Intentional underemployment or hiding income can lead a court to impute income at a level consistent with earning capacity rather than actual reported earnings.

When Courts Deviate From the Guidelines

Connecticut courts follow the guidelines in most cases, but they have discretion to deviate when the standard amount would be inequitable. Situations that might justify deviation include:

• Significant shared parenting arrangements where both parents bear substantial custody-related costs
• A child with extraordinary medical or educational needs
• An unusually high combined parental income where the standard formula produces a support amount well beyond the child’s actual needs
• Situations where strict application would leave the paying parent unable to meet their own basic needs

Deviation from guidelines requires written findings explaining why the standard amount is inappropriate.

A Simsbury family law lawyer can run through the calculation with the actual figures in your situation and identify whether any basis for deviation exists.

Modifying an Existing Support Order

Child support orders aren’t permanent. A substantial change in circumstances, such as a significant income change for either parent, a change in custody arrangements, or substantial change in the child’s needs, can provide grounds to request a modification.
