OK. What he made in the past is not important. What he is earning now is king. His CURRENT annual income is important. Current annual income is determined as follows:
Gross income from most recent pay period multiplied times the number of pay periods per year = CURRENT ANNUAL INCOME. Recent pay-stubs can serve as evidence.
Example: If he currently earns $1,000 per week, his current annual income is $52,000.
I don't anticipate an issue based on your comments.
