Minn. Stat. § 518A.32
Subd. 1. General.
This section applies to child support orders, including orders for past support or reimbursement of public assistance, issued under this chapter, chapter 256, 257, 518B, or 518C. If a parent is voluntarily unemployed, underemployed, or employed on a less than full-time basis, or there is no direct evidence of any income, child support must be calculated based on a determination of potential income. For purposes of this determination, it is rebuttably presumed that a parent can be gainfully employed on a full-time basis. As used in this section, "full time" means 40 hours of work in a week except in those industries, trades, or professions in which most employers, due to custom, practice, or agreement, use a normal work week of more or less than 40 hours in a week.
Subd. 2. Methods.
Determination of potential income must be made according to one of three methods, as appropriate:
Subd. 3. Parent not considered voluntarily unemployed, underemployed, or employed on a less than full-time basis.
A parent is not considered voluntarily unemployed, underemployed, or employed on a less than full-time basis upon a showing by the parent that:
(4) a governmental agency authorized to determine eligibility for general assistance or supplemental Social Security income has determined that the individual is eligible to receive general assistance or supplemental Social Security income. Actual income earned by the parent may be considered for the purpose of calculating child support.
[See Note.]
Subd. 4. TANF or MFIP recipient.
If the parent of a joint child is a recipient of a temporary assistance to a needy family (TANF) cash grant or comparable state-funded Minnesota family investment program (MFIP) benefits, no potential income is to be imputed to that parent.
[See Note.]
Subd. 5. Caretaker.
If a parent stays at home to care for a child who is subject to the child support order, the court may consider the following factors when determining whether the parent is voluntarily unemployed, underemployed, or employed on a less than full-time basis:
(5) the availability of child care providers.
This subdivision does not apply if the parent stays at home only to care for other nonjoint children.
Subd. 6. Economic conditions.
A self-employed parent is not considered to be voluntarily unemployed, underemployed, or employed on a less than full-time basis if that parent can show that the parent's net self-employment income is lower because of economic conditions that are directly related to the source or sources of that parent's income.
