Small Business PPE Tax Credit Act This bill allows certain small businesses a tax credit for qualified personal protective equipment expenses, up to $25,000 in a taxable year. The entities eligible for such credit include farms, veterans organizations, and tribal business concerns. The bill defines qualified personal protective equipment expenses to include the cost of equipment for reducing the risk of coronavirus (i.e., the virus that causes COVID-19) transmission, including gloves, medical masks and protective gear, and cleaning supplies.
