Well, a person could have low income and could be living off a big savings account. A person can have $200000 in the bank (big assets), but can also have low income (due to low bank interest rates, little to no employment, etc.). For Illinois Medicaid, they take into account only income, NOT assets. I did not have to tell them how much money I have in the bank.Our least favorite clients were those who came in and simply claimed to have been living on absolutely NOTHING for the past 6 months or the previous year. We'd have to dig, dig, dig harder to obtain tax records, check stubs, rent and utilities records, bank statements, and eventually pry some source of support from them (undeclared illegal income was usually the answer) but we were not able to certify anyone as low income unless they had some believable legitimate source of income in a sufficient amount to reasonably have supported them to some extent.
