State tax registration
State tax registration is required if you answer “yes” to any of the questions listed below. A tax registration cannot be transferred to another business.
- Do you plan to gross over $12,000 per year?
- Will you be selling at retail any item or product?
- Will you be repairing, installing, altering, decorating, or improving any item or product for another person (for example, car repair, construction)?
- Will you engage in a business that is responsible for any other state taxes (for example, timber, fish, litter, public utility, hazardous substance/waste)?
Note: When you register you will receive a state business license and UBI (Unified Business Identifier) number. A business license must be posted at each location where the licensee operates.
