What Is a Tax Number in Canada?

In Canada, the term “tax number” can refer to a few different identifiers. The right one for you depends on your residency status and whether you are an individual or a business owner.

• Social Insurance Number (SIN) — Used by individuals for employment and tax purposes
• Business Number (BN) — Used by businesses registered with the Canada Revenue Agency (CRA)
• Individual Tax Number (ITN) — Used by non-residents who cannot get a SIN but need to file a Canadian tax return
• Temporary Tax Number (TTN) — A temporary number assigned by the CRA while a SIN application is in progress

For most Canadians and newcomers, the Social Insurance Number is the primary tax number they will use.

Professional tax return filing services can help taxpayers understand which identification number applies to their situation.

What Is a Social Insurance Number (SIN)?

A Social Insurance Number (SIN) is a nine-digit number issued by the Government of Canada. It is your primary identifier with the Canada Revenue Agency (CRA) and is required for almost all tax-related activities in Canada.

Your SIN is used to:

• File your personal income tax return with the CRA
• Access government programs such as Employment Insurance (EI) and the Canada Pension Plan (CPP)
• Work legally in Canada
• Open registered accounts such as an RRSP, TFSA, or RESP
• File your annual income tax return
• Get your tax refund

Your SIN is confidential and should only be shared with your employer, financial institution, or the CRA. Protect it as you would any other piece of sensitive personal information.

An accountant for taxes can help newcomers understand their Canadian income tax filing obligations.

How to Apply for a SIN

You can apply for a SIN through Service Canada. There are three ways to apply:

• In person — Visit a Service Canada Centre near you. If you apply with all required documents, you can receive your SIN on the same day.
• By mail — Send certified copies of your documents to a Service Canada office.
• Online — Eligible newcomers can apply for a SIN online through the Service Canada website.

Required Documents for a SIN Application

• Proof of identity (e.g., passport, birth certificate, or permanent resident card)
• Proof of immigration status (e.g., work permit or study permit)
• Proof of Canadian address

Note: SINs beginning with the digit 9 are issued to temporary residents and have an expiry date tied to your immigration document. Applying for a SIN is free of charge.

What Is a Business Number (BN)?

If you are self-employed or operating a business in Canada, you will need a Business Number (BN) from the CRA. The Business Number is a unique 9-digit identifier assigned to your business for all CRA program accounts.

A Business Number is used for:

• GST/HST registration and remittance
• Payroll deductions for employees
• Filing corporate income tax returns (T2)
• Import and export accounts

Business tax filing requirements often depend on the CRA program accounts connected with your Business Number.

How to Get a Business Number

You can register for a Business Number directly with the CRA. The most common ways to register include:

• Online — Register through the CRA Business Registration Online (BRO) portal
• By phone — Call the CRA Business enquiries line at 1-800-959-5525
• By mail or fax — Submit a completed RC1 form to your local CRA tax centre

A corporate tax accountant can help corporations understand their registration and tax reporting requirements.

What Is a CRA My Account?

CRA My Account is a secure online portal that allows individuals to manage their tax information with the Canada Revenue Agency. Once you have your SIN or BN, you can register for My Account to:

• View your Notice of Assessment (NOA)
• Check your RRSP and TFSA contribution room
• Track your refund status
• Update your address and direct deposit information
• Access your T4, T5, and other tax slips

Registering for CRA My Account is highly recommended for all Canadian taxpayers. It makes managing your taxes significantly easier and more efficient.

Tax and accounting services can also help taxpayers understand CRA notices, assessments, and filing requirements.

Why You Need a Tax Number in Canada

Whether you are an individual, a newcomer, or a business owner, having the right tax number is essential for staying compliant with CRA regulations. Here is why:

• Receiving government benefits like the GST/HST credit, Canada Child Benefit (CCB), and Old Age Security (OAS)
• Opening a bank account or registered savings account
• Starting a job legally in Canada
• Operating a business and collecting/remitting GST/HST

Without a SIN, you cannot work legally in Canada or file a tax return with the CRA. Without a Business Number, you cannot register for GST/HST or manage payroll as a business.
