How do I find my 9 digit CRA Business Number after my federal incorporation is approved in 2026?

For most federal corporations in 2026, the CRA automatically assigns a 9 digit Business Number (BN) within 5 to 10 business days of your Certificate of Incorporation being issued. You can view this number by logging into the Corporations Canada online filing system or by waiting for the formal RC1 notification letter sent to your registered head office address. If you do not receive it within two weeks, you must contact the CRA business enquiries line at 1(800) 959-5525 with your corporate name and date of incorporation ready.

Can a non-resident director apply for a CRA program account without a Canadian Social Insurance Number?

Yes, in 2026, non-resident directors who lack a Canadian Social Insurance Number (SIN) can still register for GST/HST or Payroll accounts. Instead of a SIN, you must provide alternative identification and proof of residency on Form RC1 (Direct Request for a Business Number). You may also be required to submit a certified copy of your valid passport and a document confirming your foreign home address. While the process is slower than for residents, the CRA allows non-residents to manage Canadian entities provided all foreign director disclosure rules are met.

When must a new Ontario provincial corporation manually request a CRA Business Number?

While federal and many provincial systems are integrated, if you incorporate a specialized entity or if the automated data transfer between Ontario’s Ministry of Public and Business Service Delivery and the CRA fails in 2026, you must manually register. This is done using the CRA My Business Account portal or by mailing Form RC1. You specifically need to do this if your business activities require immediate GST/HST registration before the automated BN generation cycle completes, typically within the first 30 days of operation.

What happens if I fail to register for a 2026 GST/HST program account after receiving my Business Number?

Receiving a Business Number (BN) does not mean you are registered for GST/HST. If your corporation’s worldwide taxable supplies exceed the 30,000 CAD threshold over four consecutive calendar quarters in 2026, registration is mandatory. Failure to register can lead to the CRA assessing uncollected tax on all your sales retroactively to the date you crossed the threshold. Additionally, you will be liable for penalties and interest on the unpaid tax amounts, and you will lose the ability to claim Input Tax Credits (ITCs) on your business expenses for the period you remained unregistered.

To get a CRA Business Number (BN) after incorporating in Canada in 2026, you typically do not need to apply separately as the number is automatically generated through the data exchange between Corporations Canada (or provincial registries) and the Canada Revenue Agency. Most founders receive their 9-digit BN via mail or digital notification within 45 days of incorporation, though you must still manually activate specific 'program accounts' for GST/HST, Payroll, and Import/Export.

How is the CRA Business Number assigned in 2026?

The CRA Business Number is assigned automatically to almost all federal and provincial corporations at the point of registration. When you complete your Canada federal or provincial incorporation, the registry sends your corporate details to the CRA. The CRA then creates a unique 9-digit identifier that stays with your business for its entire lifecycle. This number is the core of your tax identity, appearing on all correspondence with the federal government.

In 2026, the integration between the federal government and provinces like Ontario, British Columbia, and Alberta is seamless. However, even though the BN is automatic, the business is not 'open' for tax purposes until you register for specific program accounts. A full CRA account identifier consists of the 9-digit BN, a two-letter program identifier (like RT for GST/HST), and a four-digit reference number (usually 0001).

Which CRA program accounts do you need to register?

You must register for program accounts based on your specific business activities and revenue levels. While the BN identifies the entity, the program accounts authorize you to collect taxes or hire employees. In 2026, the primary accounts include:

Income Tax (RC): Automatically opened when your BN is generated. This is used for your annual T2 corporate tax return.
GST/HST (RT): Mandatory if your revenues exceed 30,000 CAD in a year. Many founders register voluntarily to claim Input Tax Credits on startup costs.
Payroll (RP): Required if you hire even one employee or pay yourself a director salary. This allows you to remit source deductions.
Import/Export (RM): Necessary if you are moving physical goods across Canadian borders.

Account Type	2026 Threshold	Common Use Case
Corporate Income Tax (RC)	Always Mandatory	Filing the T2 Annual Return
GST/HST (RT)	30,000 CAD Revenue	Collecting and remitting sales tax
Payroll Deductions (RP)	Any Employee	Paying salaries and remittances
Import/Export (RM)	Any Shipment	Clearing customs for physical goods

How to register for tax accounts via My Business Account

The most efficient way to manage your 2026 CRA compliance is through the 'My Business Account' online portal. To access this, you need your 9-digit Business Number and your personal tax information to verify your identity. Once logged in, you can 'Add a Program' to create your GST/HST or Payroll accounts instantly.

If you are a non-resident founder without a Canadian Social Insurance Number (SIN), you cannot use the standard online portal. Instead, you must submit Form RC1 (Direct Request for a Business Number and Certain Program Accounts). This form requires detailed information about the directors, their residency status, and the primary business activity. Gullia Filing handles these manual registrations for international clients to ensure the 2026 non-resident disclosure requirements are fully met.

What happens if the CRA BN is not received?

If you have not received your 9-digit BN within 30 days of your incorporation date, you should check the status of your filing. Most delays in 2026 are caused by incomplete address information or mismatched director data. You can verify your BN by searching the public 'Business Number Registry' provided by the Government of Canada. If your corporation appears there but you have no official CRA letter, you can call the CRA Business Enquiries line to request an RC1 notification letter.

Annual Return: Due within 60 days of your incorporation anniversary every year. This is a corporate registry filing, not a tax return.

T2 Corporate Tax Return: Due six months after your fiscal year end, though any taxes owed must be paid within two or three months of year end.
