Work-related child care, the children's health insurance premium and uninsured medical costs above $250 per child a year are added and shared by income; the paying parent is credited for the costs they pay. The receiving parent's child care is first reduced by the child care tax credit for children under 13.
How Missouri works it out
Missouri uses the income shares model and the official Form worksheet: the schedule gives the basic amount for the parents' combined monthly income, add-ons are added, and each parent is responsible for their share of the total.
Gross income from almost all sources counts, before taxes. Court-ordered maintenance received is added and maintenance paid is subtracted.
The paying parent gets a credit of a percentage of the basic amount for their overnights a year, starting at 36 overnights and rising to the table's top band. The credit is not given when the receiving parent's adjusted income is at or below the worksheet's caveat amount, unless the paying parent would be left with little after support. With about equal time the parent with the higher gross income pays.
