How to Apply for a Canadian ITN in 2026: Complete Form T1261 Guide

A Canadian Individual Tax Number (ITN) is a nine-digit number the Canada Revenue Agency (CRA) issues to non-residents who have to deal with Canadian tax but are not eligible for a Social Insurance Number (SIN). You apply for it by mailing the CRA a paper form called the T1261. It is free, it takes about six to eight weeks, and you can do it entirely from outside Canada. That is the whole process in one paragraph, and the rest of this guide is the detail that keeps your application from coming back rejected.

I run a couple of communities for non-residents working through US and cross-border financial systems, and the Canadian ITN comes up constantly, usually tangled up with two other numbers: the US ITIN and the Canadian SIN. I am not a Canadian tax preparer, so for every procedural point below I link straight to the CRA's own pages. What I can do is clear up the confusion I see every week, especially the part most guides get flatly wrong: what an ITN actually does once you have it, and how far it gets you with Canadian banking (further than most people think).

What Is a Canadian ITN?#

The Individual Tax Number is a nine-digit tax identifier (it usually starts with a 9) that the CRA assigns to a non-resident individual who needs to interact with the Canadian tax system but cannot get a SIN. You request it on Form T1261, "Application for a Canada Revenue Agency Individual Tax Number (ITN) for Non-Residents", which the CRA publishes free on canada.ca.

Two things to fix in your head right away:

• An ITN is for tax purposes only. It is not a work permit, it does not entitle you to benefits, and it does not make you a Canadian resident. It exists so the CRA can identify you on a return, a withholding waiver, or a property sale.
• There is no fee and no online channel. The form is free, and the only way to submit it is by mail or courier. The CRA does not accept the ITN application through My Account or any electronic upload.

ITN vs SIN vs the US ITIN: What's the Difference?#

This is where most people get stuck, so it is worth thirty seconds. Four different numbers get confused with each other, and choosing the wrong path wastes months.

The ITN and the US ITIN are the two that trip people up most, because both are nine digits and the names rhyme. They are completely different numbers from different governments. If you are a Canadian (or anyone else) who actually needs the US number, that is a separate process: see our guides on how to apply for a US ITIN from Canada and how to get a US ITIN, plus our explainer on what an ITIN is. For a side-by-side on the broader tax-ID family, we wrote up TIN vs ITIN too. This article is only about the Canadian ITN.

One rule the CRA is strict about: do not apply for an ITN if you already have, or are eligible for, a SIN, an ITN, or a TTN. If you are in Canada on a study permit or work permit that lets you work, you are SIN-eligible and must apply for a SIN through Service Canada instead.

Who Needs a Canadian ITN (and Who Doesn't)?#

You apply for an ITN when you are a non-resident, you are not eligible for a SIN, and you need a tax number for one of these reasons the CRA lists on the form:

• Filing a Canadian income tax return (for example, an international student without a work permit who has to file).
• Waiving or reducing Canadian withholding tax on payments you receive.
• Disposing of taxable Canadian property, such as selling Canadian real estate.
• Filing a section 216 election on Canadian rental income.
• Filing an Underused Housing Tax (UHT) return.

If none of those apply to you, you probably do not need an ITN yet. And if you are eligible for a SIN, the ITN is the wrong number: the CRA wants you to use the SIN, and applying for both creates a mess.

How to Apply for a Canadian ITN: Step by Step#

The application is genuinely simple. The reasons it fails are almost always document certification and a missing checkbox, not the form itself. The whole sequence is below.

Step 1: Download and Fill Out Form T1261#

Get the form from the official CRA T1261 page. One practical snag: it is a fillable PDF that some browsers' built-in viewers cannot save. Right-click the link, choose "Save link as," and open the downloaded file in the free Adobe Acrobat Reader so your typing actually sticks.

On the form you:

• Check the box for your reason for applying (filing a return, reducing withholding, disposing of property, and so on). The CRA specifically warns that skipping this causes delays.
• Check the box for the supporting documents you are including.
• Enter your identification details in sections 1 to 4: legal name, date of birth, foreign address, and contact information.

Step 2: Gather and Certify Your Identity Documents#

Your documents have to prove your name, date of birth, and photo. A valid passport does all three on one document, which is why it is the cleanest option. If you do not use a passport, you combine two or more documents to cover all three elements.

You can send the CRA one of three things:

• Original documents. The CRA will mail your originals back to you.
• A certified copy. The CRA keeps it (certified and notarized copies are not returned).
• A notarized copy.

Here is a detail worth its own sentence, because it is the single biggest difference from the US system: the CRA accepts a notarized copy of your passport, and the US IRS does not. If you have ever been told a notarized passport copy gets rejected, that was advice for the US ITIN (Form W-7), not the Canadian ITN. Do not let the two sets of rules bleed together.

To count as certified, the CRA requires the copy to be signed by one of these people, with an original ink signature, their official title, their address, and their phone number, and a note that it is a true copy of the original:

• a public notary
• a lawyer
• a medical physician
• a chartered professional accountant (CPA), who must include their membership identification

You cannot certify your own documents.

Step 3: Sign the Form#

Sign it with an original, wet-ink signature. There is no electronic signature option for the ITN application, which follows from the fact that the whole package goes in the mail.

Step 4: Mail It to the Sudbury Tax Centre#

Send the signed form and your documents to the CRA's ITN unit. Use a tracked or courier service so you can prove it arrived.

How Long Does a Canadian ITN Take?#

The CRA's official answer is six to eight weeks from the date it receives your application to the date it mails your written ITN notice. Plan around that number.

You will see blogs (including, honestly, the older version of this one) quote faster times like "two to three weeks." Treat those as anecdotes, not the rule. The only figure the CRA stands behind is six to eight weeks, and I would build your timeline on it. If eight weeks pass with no reply, you can call the CRA's individual tax number line at 1-866-223-4403 from inside Canada, or 705-669-5130 (collect calls accepted) from outside Canada.

Two timing tips that are genuinely useful:

• Apply early. If you need the ITN for a filing deadline, a tax slip, or a property closing, start well ahead. For a real-estate sale in particular, the related clearance-certificate process (Form T2062) also runs on a six-to-eight-week clock, so non-residents typically start it a month or more before closing.
• A deadline will not wait for your ITN. If your filing deadline arrives before the number does, the CRA's guidance is to file the return anyway with a note explaining the ITN is pending, so you avoid late-filing penalties and interest.

Some applicants also use a Canadian mailing address (a friend's place or a paid virtual mailbox for around $10 a month) so the CRA's reply does not have to travel internationally. It can shave time off the return leg of the mail, but there is no evidence it speeds up the CRA's actual processing, so treat it as a convenience, not a shortcut.

Why Do ITN Applications Get Rejected?#

When a T1261 comes back, it is almost always one of two reasons:

• The document certification was done wrong. A plain photocopy, a missing certifier title or phone number, a photocopied (rather than original ink) signature, or certification by someone outside the CRA's accepted list. Get this part right and you have removed most of the risk.
• The reason-for-applying box was left blank. The CRA processes the form based on why you say you need the number. No box, no clean processing.

Send a complete, properly certified package the first time and you avoid the months that a round-trip rejection costs.

Can You Open a Bank Account With a Canadian ITN?#

Yes, and I have done it myself: I opened both Neo and Wealthsimple using my ITN. In most Canadian banking forms your ITN goes exactly where a SIN would, and the account opens. Here is how to do it and which products to start with.

You Don't Even Need a SIN#

Most people assume a SIN is mandatory for a Canadian bank account. It is not. Under the federal Access to Basic Banking Services Regulations, a bank must open a basic deposit account for you on acceptable ID, and the Office of the Privacy Commissioner confirms a SIN is only required for accounts that earn taxable interest. Your ITN is all the tax number you need for everyday banking, and on a CRS or FATCA self-certification it stands in as your Canadian taxpayer identification number.

How to Open Neo and Wealthsimple With an ITN#

Both apps ask for a tax number at signup. Put your ITN where the SIN goes, and the account opens. To make it smooth:

• Have a Canadian address ready. Your own, or a virtual mailbox for around $10 a month.
• Start with the products that never ask for a SIN. Wealthsimple's Cash account and Neo's cards are the easy entry points. Only registered accounts like a TFSA or RRSP still want a SIN.
• Add a secured card to build credit from zero. The Neo Secured card approves people with no Canadian history and reports to both Equifax Canada and TransUnion, so it builds a real credit file fast. KOHO is a no-credit-check alternative.

Here is where each app stands, checked against their own eligibility pages in June 2026.

Build Canadian Credit Alongside Your Account#

Opening the account is step one. The bigger win is a Canadian credit file, and your ITN gets you there too. A secured card (Neo or KOHO) is the fastest start, and the big-bank newcomer programs (RBC Newcomer, TD New to Canada, Scotiabank StartRight, BMO NewStart, and CIBC Smart for Newcomers) bundle a chequing account with a starter credit card on your immigration documents and photo ID, with no Canadian credit history required. If you are weighing options, our guide to the best banks for newcomers and students breaks down the tradeoffs.

What Can You Do With a Canadian ITN?#

Your ITN unlocks the tax tasks that probably sent you here in the first place:

• File your Canadian return. Write the ITN where the form asks for your tax number.
• Reclaim over-withheld tax. Non-resident (Part XIII) tax is usually withheld at a flat 25% on Canadian-source income like rent, though a tax treaty can lower the rate. Filing a return, frequently under a section 216 election for rental income (the section 216 return is Form T1159), is how you get the excess back.
• Handle a property sale. Disposing of Canadian real estate as a non-resident runs through Form T2062 and a clearance certificate, and your ITN is the identifier on that file. Without the certificate, the buyer is required to withhold a large slice of the sale price, so start early.

If your situation also touches US tax, the Canada-US picture matters, and our Canada-US tax treaty guide is a good next read.

Frequently Asked Questions#

Is a Canadian ITN the same as a US ITIN?#

No. A Canadian ITN is issued by the Canada Revenue Agency for Canadian tax. A US ITIN is issued by the IRS for US tax. They are different numbers from different countries, and they follow different rules, including on document certification (the CRA accepts notarized passport copies; the IRS does not).

How much does it cost to get a Canadian ITN?#

Nothing. Form T1261 is free, and the CRA does not charge to issue an ITN. Your only costs are document certification (often $20 to $50 if you use a local notary or lawyer) and postage.

Can I apply for an ITN online?#

No. The CRA does not accept the ITN application electronically or through My Account. It must be mailed or couriered to the Sudbury Tax Centre with an original ink signature.

How long does a Canadian ITN take?#

The CRA states six to eight weeks from when it receives your application. If you have heard faster, treat it as an anecdote and plan for the official window.

Do I need a Canadian address to apply?#

No. You apply with your foreign address. A Canadian mailing address is optional and can speed up the return mail, but it does not change the CRA's processing time.

Can I open a Canadian bank account with just an ITN?#

Yes. A basic chequing account in Canada does not legally require a SIN, so your ITN is all you need on the tax line. I have opened both Neo and Wealthsimple with an ITN: put it where the form asks for a SIN, and keep a Canadian address handy for signup.

Does Wealthsimple or Neo accept an ITN instead of a SIN?#

Yes. I opened both with my ITN in the SIN field. Start with the products that do not require a SIN, like Wealthsimple's Cash account and Neo's cards, then add the Neo Secured card to build credit. Only registered accounts such as a TFSA or RRSP still ask for a SIN.

Who can certify my documents for the ITN?#

A public notary, a lawyer, a medical physician, or a chartered professional accountant. They must sign in original ink and include their title, address, and phone number, and a CPA must add their membership ID. You cannot certify your own documents.

A Quick Note If You Actually Need the US ITIN#

A lot of people land on "Canada ITN" pages when the number they really need is the US ITIN, for example a Canadian with US rental income, US investments, or a US tax-filing requirement. The Canadian ITN above is a free, do-it-yourself process with the CRA. The US ITIN is a different application (IRS Form W-7), and that is the one Taxsym handles end to end, including certifying your passport so you never mail the original.
