Actually, according to the initial agreement, businesses have until 2026 to repay their loans, but, in that case, they would forfeit the loan forgiveness of $20,000.
Businesses may negotiate an agreement with their bank, which would allow them to receive that refundable portion. I say that as a former commercial banker. They nevertheless have to show they have exercised due diligence. That's the way it is in the business world: when you borrow money, you have to repay it one day or another. Otherwise a business simply has no capital.
