Danbury economic development officials are alerting local companies that starting today, at 9am, the U.S. Small Business Administration will open a 14-day, exclusive PPP loan application period for businesses and nonprofits with fewer than 20 employees. Self-employed and sole proprietors can now use gross income (versus net income) to calculate the PPP loan amount, increasing potential loan size.  Business owners behind on their federal student loan payments are now eligible for PPP loan forgiveness.
