My company filed for two PPP loans to keep afloat. Any company could have just kept making money and the owners could have pocketed the cash. There were expectations that employees were not fired and other questions in the application that I can’t recall. When we applied for forgiveness on the loans we provided tax receipts and staff numbers over time. I’m sure it would have been pretty straightforward to lie or find someone to lie for you (accountant with less than stellar ethics).
