How to apply for an Individual Tax Number (ITN)

An Individual Tax Number (ITN) is a unique number that Canada Revenue Agency (CRA) uses to identify you for tax purposes if you aren't eligible for a Social Insurance Number (SIN) (e.g., because you don’t have a study permit allowing you to work).

Overview of the application process

Supporting documents

In addition to the application form, you'll need to submit:

  • Photocopy of passport bio-data page (i.e. the page containing your name and photo)
  • UBC enrolment letter
  • If you have a study permit: photocopy of your study permit
  • If you do not have a study permit, submit all of the following:
    • Photocopy of passport page(s) containing entry stamps to Canada
    • Photocopy of any UBC scholarship or award offer letters (if applicable)
    • Proof of request for an ITN from Enrolment Services (if applicable)
    • Cover letter explaining why you need an ITN

Mailing the application

We suggest using Canada Post Xpresspost to mail your documents securely. If you do not receive your ITN within 6 weeks, you can call the Canada Revenue Agency's International Tax office.

We highly suggest applying for an ITN from within Canada (i.e. before you leave Canada). If you have already left Canada and you need to apply for an ITN, we suggest you include a cover letter explaining your situation to avoid confusion and delay. You may call the Canada Revenue Agency's International Tax office before submitting your application to ensure your application contains sufficient documentation.

Understanding the form

Reason for applying

Reason for applying for ITN field

Indicate "Filling a Canadian income tax return" as the reason you are applying for an ITN.

The difference between Foreign address and Mailing address

Foreign address and Mailing address fields

The “Foreign Address” refers to your address in the country where you permanently or normally reside. The “Mailing Address” refers to a Canadian address to which the CRA will send the written notification of your ITN.

What do I put for “Foreign Tax Identification Number”?

If you don’t have a Foreign Tax Identification number, you may write “N/A”.

Who should sign under the “CERTIFICATION” section at the bottom of the application form?

certification field

You should. The local official (e.g. your professor) should sign and certify the PHOTOCOPY of your passport and study permit.

Tips

Can I work with an ITN?

No. To start working in Canada and receive benefits from employment, you need to apply for a Social Insurance Number (SIN) to replace your ITN.

What if I forgot to apply for ITN before the Tax Season?

Do not apply for an ITN in late February or March as it takes about 4-6 weeks to process. You may send your ITN application AND the tax return to the same address specified at the back of ITN form.

Does an ITN expire? Do I have to renew ITN?

No. The ITN does not have an expiry date and once you are issued an ITN, you can use it for future tax filing purposes. But remember that if you get a job in the future, you will need SIN.

If I lost my ITN or need to make changes to my personal info, should I apply for a new ITN?

No. You must contact the Canada Revenue Agency (CRA) to notify them about the lost ITN or changes to your personal information. You can then either get your previous number re-issued or keep using the number you have.

Do I need an ITN to file my taxes?

If you plan on filing your tax return just once, you do not need ITN as the CRA will assign you a temporary taxation number for a single tax return. However, you will need an ITN if you need to file more than one Canadian tax return so CRA can trace your records.

I am outside Canada. Can I get my documents certified by a doctor/lawyer/professor/etc. outside Canada in order to submit my ITN application on time?

Yes.
