On 6/22/20 the SBA issue a new set of Interim Finals Rules (one of many) that helped to clarify some issues but not all. Here is what you need to know:
As of now, you have 8 weeks (56 days) from date money hits your bank account to spend the funds (Covered Period). But you can elect to start the 8 weeks for the payroll costs from the first payroll period date after you receive the funds (Alternative Payroll Covered Period (APCP)) instead. For those that receive funds after 6/5, you automatically have 24 weeks to spend the funds. Those that received the funds pre 6/5 can elect to use the 24 weeks also.
