This bill amends the existing child support guidelines by revising the definitions and calculations related to adjusted gross income, parenting time, and child support obligations. Key changes include the repeal and reenactment of the definition of "adjusted gross income" to include specific deductions such as court-ordered support, self-employed tax, retirement contributions, state income tax, and allowable child care expenses. The bill also redefines "parenting time" to reflect the number of days a child spends with each parent and introduces a "parenting time factor" (PTF) that adjusts the calculation of child support obligations based on the time each parent spends with the child. Additionally, the total support obligation will be calculated by multiplying the parents' total net income by a percentage derived from the guidelines and the PTF.

Further, the bill establishes a self-support reserve for obligor parents, ensuring that child support obligations do not exceed their adjusted gross income when it is below certain thresholds. It also allows for adjustments to child support obligations based on special circumstances, such as the agreement on variable expenses between parents and the financial capabilities of the lower-earning parent. The act is set to take effect on January 1, 2027, and is expected to incur a one-time cost of approximately $290,000 for system upgrades and potential vendor consultation to implement these changes.
