Paycheck Protection Small Business Forgiveness Act This bill modifies loan forgiveness under the Paycheck Protection Program established to support small businesses in response to COVID-19 (i.e., coronavirus disease 2019). Specifically, the bill provides for automatic forgiveness of a paycheck protection loan that is not more than $150,000 if the recipient submits a one-page form. Such form must allow a recipient to submit specified demographc and expenditure information, and certain individuals (e.g., the President, the Vice President, or the head of an executive department) are not eligible for such forgiveness. Further, the bill prohibits any enforcement or other action against a lender relating to loan origination, forgiveness, or guarantee based on the lender's reliance on certifications or documentation submitted by a loan applicant or recipient.
