Under what circumstances can a parent pay less child support?

The court may consider any of the following factors in determining whether to allow a parent to pay less child support than it would otherwise. This is called a “deviation.”
Special and unusual needs of the children
Extraordinary obligations for minor children or obligations for handicapped children who are not stepchildren and who are not offspring from the marriage or relationship that is the basis of the immediate child support determination
Other court-ordered payments
Extended parenting time or extraordinary costs associated with parenting time
The obligor obtaining additional employment after a child support order is issued in order to support a second family
The financial resources and the earning ability of the child
Disparity in income between parties or households
Benefits that either parent receives from remarriage or sharing living expenses with another person
The amount of federal, state, and local taxes actually paid or estimated to be paid by a parent or both of the parents
Significant in-kind contributions from a parent, including, but not limited to, direct payment for lessons, sports equipment, schooling, or clothing
The relative financial resources, other assets and resources, and needs of each parent
The standard of living and circumstances of each parent and the standard of living the child would have enjoyed had the marriage continued or had the parents been married
The physical and emotional condition and needs of the child
The need and capacity of the child for an education and the educational opportunities that would have been available to the child had the circumstances requiring a court order for support not arisen
The responsibility of each parent for the support of others
Any other relevant factor
