I have seen no such distinction on the IRS website. As per the IRS: "The vast majority of people do not need to take any action....The economic impact payment will be deposited directly into the same banking account reflected on the return filed."
So, as per the information we currently know, it seems that if there is a bank account # and routing # on the tax return (regardless of pay or refund) that is the information they will use to make a direct deposit.
