Business owners change the name of existing companies for many reasons. You might have decided to take your company in a new direction, expanded your business or created a new partnership. Your business might even have a new location that could warrant a business name change. Whatever the reason, changing a business name in New Jersey involves alerting all the appropriate government offices.

Contact the New Jersey Department of Treasury, Division of Revenue. This department should be among the first to know of your business name change so that processing your business taxes continues to flow smoothly. The cost for filing an alternate business name is $50, and you need to fill out form C-150G.

Register your new name with the Department of Labor and Workforce Development. The form that you need to fill out is NJ-REG-C-L and needs to be submitted to the following address. (The Department of Labor can be contacted through the Department of Treasury, according to the Department of Labor's website.)

Tell the county clerk’s office that you originally registered your business with about the name change. The office will tell you what forms you will need to change your business name with the county clerk.
