According to one of the local dental lenders:

We are soon expecting an update from management and SBA about forgiveness, I shall keep you posted. You can apply as early as June 30th for forgiveness. That’s when the first phase customers 8 weeks end. Rumor is that date may be extended for businesses that are closed (dentists which is my major portfolio). More to come on that…

In the meantime, we have a flood of questions on forgiveness from customers and I am sending them this link of FAQ’s,

S&S NOTE: So many decisions hinge on whether there will be any flexibility with the 8-week coverage period.  Hopefully the SBA will issue guidance very soon so we can help you make the best decision about the PPP, EIDL, and ERC. We’ll email everyone as soon as we can once the SBA finally issues guidance on the PPP forgiveness calculation.
