Anyone know when the sales tax hike takes effect? I know that we are going from 6% to 7%, but I am not completely sure as to when. NJ and You: The perfect place to live and Work. Where else can you pay the highest auto insurance, high property tax, high sales tax, have rules and regulations out your ears when it comes to running your biz, and have nothing in return. What exactly are the benefits of living in Jersey??? O.K. enough venting. I'm happy again.
