When a parent has a written earning record, such as paystubs or employer verification, use:
- Actual monthly gross income; or
- The average of the actual gross monthly income for the time the parent was employed during the previous three years. 
- A parent has three months of pay stubs showing an hourly wage of $9.50 and an average of 38 hours per week of work time. To find the average monthly earnings, use the following calculation: $9.50/hour x 38 hours/week x 52 weeks/year divided by 12 months = $1,564.33
When there is evidence of a parent’s employment for the last three years but the employment is not continuous, use the average of the last three years income for time periods when the parent was actually employed.
Biological Parent (BP) Receiving Family Assistance Benefits
When the BP is receiving family assistance benefits, use actual income in the child support computation when that information is available.
- You may research wage information in the Information Management System (IMS) and case notes in the Family Assistance/Client Services (FACS) system.
Otherwise, impute an amount based on the parent’s work history, education, training, and ability to work. If those options are unavailable, impute minimum wage for a 40-hour work week.
