For purposes of determining eligibility for modified adjusted gross income (MAGI)–based Washington apple health (WAH) (see WAC 182-509-0300):

(1) If the person has worked long enough at the business to file a federal tax return for the previous year and it represents his or her current income, the agency determines self-employment income by using the income and deductions claimed on the previous year's tax return.

(2) If the person has not worked long enough at the business to file a federal tax return in the previous year, the agency permits a determination of monthly self-employment income by:

(a) Adding together gross self-employment income and any profit made from selling business property or equipment over the period of time the business has been in operation within the last year;

(b) Subtracting business expenses and income deduction expenses allowed by the Internal Revenue Service that the person would be entitled to if they were filing a full year return; and

(c) Averaging the income to come up with a monthly amount based on the period of time the business has been in operation within the last year.

(3) If the person's current income does not represent his or her projected income as evidenced by clear indications of future changes in income, the agency permits the person to estimate a monthly amount by averaging income over a representative period of time.
