Setting up a business in Canada is an exciting journey, but it also comes with its fair share of challenges, especially when it comes to compliance and regulations. One of the first steps to formalizing your business and ensuring you operate legally is obtaining a Business Number (BN) from the Canada Revenue Agency (CRA). In this guide, we’ll cover what a Business Number is, why it’s important, and provide a straightforward step-by-step process on how to get one.
What is a Business Number (BN)?
A Business Number (BN) is a unique 9-digit identifier assigned by the CRA to businesses and organizations in Canada. It’s essential for several reasons, including:
- Identifying your business for tax purposes.
- Accessing various federal programs and services.
- Facilitating the registration for GST/HST, payroll deductions, and corporate income tax.
Having a BN streamlines communication between you and the government, making it easier to handle your business’s tax obligations.
Why Do You Need a Business Number?
Obtaining a Business Number is essential for any business operating in Canada, whether you are self-employed, running a small enterprise, or establishing a corporation. Here are a few compelling reasons to obtain a BN:
- Legal Compliance: Most businesses are required to have a BN for tax reporting.
- Financial Transactions: A BN helps in opening a business bank account.
- Efficient Registration: A BN is often necessary for provincial registrations, including those done in Ontario.
In absence of a BN, your ability to conduct business effectively could be severely hindered.
When Should You Get a Business Number?
You should consider obtaining a Business Number as soon as you decide to start your business. However, there are specific triggers that should prompt you to apply:
- If you plan to collect Goods and Services Tax (GST) or Harmonized Sales Tax (HST).
- If you intend to hire employees and need to register for Payroll Deductions.
- If you are planning to import or export goods.
If you’re unsure whether you need a BN, it’s best to consult with a professional or check the CRA website.
How to Apply for a Business Number
Applying for a Business Number from the CRA can be done online or by other means, depending on your preference. Here’s a detailed step-by-step process:
Step 1: Gather Necessary Information
Before you proceed with the application, make sure to collect the following essential information:
- Your legal business name and any trade names.
- Your business address, including province and postal code.
- Your social insurance number (SIN) or the SIN of the business partners.
- Description of your business activities.
- Incorporation number (if applicable).
Having this information ready will streamline the application process.
Step 2: Choose Your Application Method
You can apply for your Business Number through three main methods:
- Online: The easiest way to apply is through the CRA’s Business Registration Online (BRO) service. Visit the CRA website and follow the instructions.
- By Mail: You can also fill out Form RC1, “Request for a Business Number,” and send it to your nearest Tax Centre. This method may take longer.
- By Phone: If you prefer, you can call the CRA’s business inquiries line at 1-800-959-5525, where an agent can assist you in obtaining your BN.
Step 3: Complete the Application
Follow through with the online or offline application based on your chosen method. Ensure that all details you provide are accurate and complete to avoid delays in processing.
Step 4: Receive Your Business Number
Once your application is processed, you will receive a Business Number, which you must keep safe. You will need to use this number for all subsequent tax-related dealings with the CRA.
After Obtaining Your Business Number
Once you have your Business Number, there are a few actions you should consider taking:
- Register for GST/HST if your revenue exceeds the threshold.
- Open a business bank account using your BN for financial transactions.
- Keep records of all your tax submissions associated with your BN.
Always ensure to stay compliant with both federal and provincial regulations, especially if you are operating in Ontario.
Conclusion
Receiving a Business Number from the CRA is one of the fundamental first steps in establishing a business in Canada. Whether you are starting a small venture or a large corporation, having a BN is essential for your business activities, tax obligations, and compliance.
