Does this count as income on FAFSA

Hi! My son is applying to several pricey technical colleges:). We are set to do the FAFSA this week but I have a question. He has a disabled sibling that receives a state-funded waiver which includes parental pay because his disability is medical and requires nursing level care. As of last year, that income was declared by IRS as no longer taxable, falling under the same umbrella as payment for foster care. Does this count as income I need to report on the FAFSA? It is a unique situation and I can’t find the answer anywhere. Thanks!
