That a child support order should not exceed the obligor's ability to pay is a rebuttable presumption.
The court calculates the obligor's income available for support by subtracting a monthly self-support reserve equal to 120 percent of the federal poverty guidelines for one person from the obligor's gross income. If the obligor's income available for support is equal to or greater than the obligor's support obligation, the court will order child support.
If the obligor's income available for support is more than the minimum support amount, but less than the guideline amount, then the court applies a reduction to the child support obligation in the following order, until the support order is equal to the obligor's income available for support:
If the obligor's income available for support calculated is equal to or less than the minimum support amount or if the obligor's gross income is less than 120 percent of the federal poverty guidelines for one person, the minimum support amount applies.
If the basic support amount applies, the court orders the following amount as the minimum basic support obligation:
If the court orders the obligor to pay the minimum basic support amount, the obligor is presumed unable to pay child care support and medical support.
If the court finds the obligor receives no income and completely lacks the ability to earn income, the minimum basic support amount does not apply.
These rules do not apply to an obligor who is incarcerated.
