Establishes Main Street Economic Growth Program to encourage business development in certain small municipalities.

This bill establishes the Main Street Economic Growth Program to support business development in small municipalities with populations under 11,000 that are county seats, contain opportunity zones, or are over 70% developed according to state land use data. The program provides tax credits equal to 15% of employee compensation expenses for businesses meeting specific criteria and participating in the program, along with financial assistance through a dedicated fund for loans, loan guarantees, and technical support. Municipalities must designate Main Street areas with a statement of economic development policy, and the New Jersey Economic Development Authority will administer the program, requiring annual reporting on its impact including jobs created and capital investment.
