Tax Identification Number

The Social Insurance Number (SIN) required for tax purposes and employment in Canada.

Sections

1. Purpose of the SIN in Canada

The SIN is primarily used for:

  • Employment: Employers require your SIN to report income to the Canada Revenue Agency (CRA).
  • Taxation: The SIN is used to file income tax returns and access tax-related benefits.
  • Government Benefits: It is required to access federal and provincial programs such as Employment Insurance (EI), the Canada Pension Plan (CPP), and other social services.

2. National Regulations Governing the SIN

The SIN is regulated under the Employment Insurance Act and the Privacy Act. Key regulations include:

  • Confidentiality: The SIN is considered sensitive personal information. It should only be shared when legally required (e.g., with employers, financial institutions for tax purposes, or government agencies).
  • Eligibility: The SIN is issued to Canadian citizens, permanent residents, and temporary residents authorized to work in Canada.
  • Expiration for Temporary Residents: SINs issued to temporary residents (e.g., work or study permit holders) begin with the number "9" and have an expiration date that matches the validity of their permit.

3. Costs Associated with Obtaining a SIN

Obtaining a SIN is free of charge. There are no fees for:

  • Applying for a new SIN.
  • Renewing an expired SIN.
  • Replacing a lost or stolen SIN.

4. Standard Procedures for Obtaining a SIN

The process for obtaining a SIN is straightforward and can be completed in person, online, or by mail. Below are the steps:

A. Applying for a SIN in Person

  1. Visit a Service Canada Centre: Locate the nearest Service Canada office using their online locator tool.
  2. Bring Required Documents:
    • For Canadian Citizens: Birth certificate or Canadian citizenship certificate/card.
    • For Permanent Residents: Permanent resident card, Confirmation of Permanent Residence (COPR), or Record of Landing.
    • For Temporary Residents: Work permit or study permit issued by Immigration, Refugees and Citizenship Canada (IRCC).
  3. Receive Your SIN: If your documents are in order, you will receive your SIN during the visit.

B. Applying for a SIN Online

  1. Access the Online Portal: Visit the Service Canada website and navigate to the SIN application page.
  2. Upload Required Documents: Submit clear, legible copies of your identification documents.
  3. Processing Time: Applications are typically processed within 20 business days, and your SIN will be mailed to you.

5. Country-Specific Considerations for Visitors and Immigrants

A. Visitors

  • Visitors to Canada who do not have a work or study permit are not eligible for a SIN. If you are visiting Canada for tourism or short-term purposes, you do not need a SIN.

B. Immigrants (Permanent Residents and Temporary Residents)

  • Permanent Residents: You are eligible for a SIN upon arrival in Canada. It is one of the first steps to take after landing.
  • Temporary Residents: If you have a valid work or study permit, you can apply for a SIN. Ensure that your SIN is renewed if your permit is extended.
  • International Students: You can apply for a SIN if your study permit includes a condition allowing you to work on or off campus.

C. Protecting Your SIN

  • Only provide your SIN when legally required (e.g., to employers, financial institutions, or government agencies).
  • Avoid sharing your SIN over the phone, email, or text unless you are certain of the recipient's legitimacy.
  • If your SIN is lost or stolen, report it to Service Canada and monitor your financial accounts for suspicious activity.

D. Expired SINs

  • If your SIN begins with "9" and has expired, you must renew it by providing an updated work or study permit.

6. Additional Tips

  • Keep Your SIN Secure: Memorize your SIN and store the physical document in a safe place. Avoid carrying it with you unless necessary.
  • Tax Filing Without a SIN: If you are not eligible for a SIN but need to file taxes (e.g., as a non-resident earning Canadian income), you can apply for an Individual Tax Number (ITN) through the CRA.
  • Name Changes: If your legal name changes (e.g., due to marriage), update your SIN information with Service Canada.

7. Contact Information for Assistance

  • Service Canada: For SIN-related inquiries, visit the official website at www.canada.ca or call 1-866-274-6627 (toll-free in Canada).
