Business numbers are tied to tax programs such as the goods and services tax and harmonized tax. If your company has no intentions of hiring employees, you can usually skip the BN. However, if you are hiring staff and plan to sell a certain amount taxable goods, a BN for each program is mandatory.Partnerships are required to register with provincial and territorial government agencies. Keep in mind that each territory has its own registration guidelines.Registration involves filling out the required paperwork, including the BN number (if applicable), and paying a registration fee. In return, you receive a Master Business Licence. Your MLB is legal proof that you’re authorized to operate your business. Online registration is available in most provinces, or you can fill out paper forms and send them via postal mail to the appropriate government office.Registering your business partnership goes smoothly when you and your partners choose the right legal structure, determine if a BN is necessary, and create a unique business name.
