Working on my first 3508EZ. I have seen and read so much information on all of this, now I can't find half of what I think I read. Am I correct in that if a client satisfies the forgiveness just with gross payroll, there is no need to input all of the other information (ie utilities, interest, etc), or submit backup for anything other than the payroll? For example, if the PPP loan was for $150,000 and their gross payroll for the covered period was $300,000, can we just submit the payroll information and quarterlies? Can anyone think of any drawbacks to doing it this way?
