What Is a Business Number (BN)?
A Business Number (BN) is your business's unique identifier with the Canada Revenue Agency (CRA). Think of it as your business's permanent CRA identity. As your business grows, the CRA can attach additional program accounts—such as GST/HST, payroll, corporate income tax, or import/export—to this same Business Number. Most businesses only ever have one BN, regardless of how many CRA program accounts they eventually need.
What Is a GST/HST Number?
A GST/HST Number isn't a completely separate business number. It's a GST/HST program account that is linked to your Business Number and used for collecting, reporting, and remitting GST or HST. Once your business is required—or chooses—to register for GST/HST, the CRA creates this program account under your existing Business Number.
When Do You Need Both?
Not every business needs a GST/HST Number immediately, but every GST/HST account is connected to a Business Number. Many new Canadian service businesses begin with only a Business Number and later register for GST/HST after exceeding the Small Supplier threshold or voluntarily registering to collect sales tax. Registration requirements vary depending on your business activities and circumstances, so it's always a good idea to consult your accountant or tax professional before registering for GST/HST or making tax-related decisions.

Frequently asked questions
- Is a Business Number (BN) the same as a GST/HST Number?
- No. A Business Number (BN) is your business's unique identifier with the Canada Revenue Agency (CRA). A GST/HST Number is a tax program account that is attached to your Business Number when your business registers to collect and remit GST/HST.
- Do I need a Business Number before I register for GST/HST?
- Yes. A GST/HST account is linked to a Business Number. If you don't already have a BN, one is generally created as part of your GST/HST registration process.
- Can I have a Business Number without a GST/HST Number?
- Yes. Many Canadian service businesses have a Business Number before they're required to register for GST/HST. Whether you need a GST/HST account depends on your business activities, revenue, and CRA registration requirements.
- Does LawnJobOS support businesses before they register for GST/HST?
- Absolutely. LawnJobOS is designed for Canadian service businesses at every stage, whether you're just starting with a Business Number or you're already registered for GST/HST and managing customer bookings, payments, and invoicing.

- Should I speak with my accountant before registering for a GST/HST Number?
- Yes. Every business is different. While understanding the relationship between a Business Number and a GST/HST Number is an important first step, your accountant or tax professional can help determine when registration is required and ensure your business is set up correctly.
