Establishes Main Street Assistance Program to encourage business development in small municipalities.

S 2744 establishes the Main Street Assistance Program to provide financial and technical assistance to businesses in designated Main Street areas of small municipalities (population under 20,000 or under 11,000 if a county seat). To qualify, businesses must have at least 15% of full-time employees residing in the municipality, and the program offers tax credits equal to 15% of employee compensation expenses. The New Jersey Economic Development Authority administers the program, providing loans, loan guarantees, and technical assistance to eligible businesses and municipalities. The authority must report annually on program impact, including jobs created, capital investment, and participation rates. This initiative targets small municipalities that don't qualify for other state business assistance programs to stimulate economic growth in their commercial areas.
