Odds are you were not overcharged. Although Central Avenue is a UEZ, not all shops charge the reduced sales tax. Each business must first register with the Jersey City Urban Enterprise Zone program. For varying reasons, not all businesses qualify and therefore must collect the full sales tax amount. Most Central Avenue businesses registered with the program display a UEZ decal on their windows. Don’t see a UEZ decal? Ask the store manager about the reduced sales tax program. Your inquire may encourage the owner to qualify and register with the UEZ program which can only help you the next time you shop.
