PPP deductibility

The CARES Act says that forgiven PPP loans are nontaxable. But there has been no legislation on whether expenses funded by PPP loan proceeds are tax deductible. IRS has said to prevent a double tax benefit the expenses are not deductible. Congress seemed willing to reverse this but hasn’t as of yet. Depending on the PPP amount and tax bracket this can cause a major increase in tax. Your thoughts? Thank you !
