Do I need a New Jersey sales tax ID? If so, how do I get one?
Anyone who makes retail sales in this state is doing business in New Jersey and must comply with the state tax laws. New Jersey requires all vendors, even seasonal businesses and one-time vendors, to register with the state for tax purposes at least 15 business days before starting business, and to collect New Jersey sales tax on all sales of taxable tangible personal property or services. There are no special provisions for temporary vendors. Once registered, you must file all required returns until you properly end your tax registration with New Jersey.
File Form NJ-REG (Business Registration Application) to register with the state to collect/remit New Jersey taxes such as sales tax or employee withholdings, and to obtain a New Jersey tax identification number. You can register online or file a paper application. For additional information on registering your business visit the state's website.
