There Is No Single CRA Fax Number
Unlike a national hotline, the Canada Revenue Agency routes fax to the specific tax centre, office, or program handling your file — so the correct number depends on what you're sending and where your file lives. The reliable source for the right number is:
- The CRA notice, letter, or form you received — it lists the fax number for that matter
- The CRA agent you spoke with, who gives you a fax number when they request documents by fax
- The CRA tax centre directory for the centre that serves your region
Don't reuse a fax number from an unrelated letter — sending to the wrong centre can delay processing. Always use the number tied to your current matter.
When People Fax the CRA
Fax is still accepted by the CRA in several common situations:
- Sending documents a CRA agent asked for during a call or review
- Submitting authorization or representative forms
- Responding to a notice or request for additional information
- Filing where the form's instructions or your tax centre specify a fax number
For many submissions the CRA now prefers its Submit documents online service or My Account, but when fax is the requested or available channel, it works from anywhere with FaxTerra.
How to Fax the CRA with FaxTerra
Save your document as a PDF or take a photo of it. Upload it here, enter the CRA fax number from your notice or form, preview it, and send. There's no fax machine and nothing to install. Use a cover sheet that includes your name, your CRA business or social insurance number reference exactly as it appears on your correspondence, and the matter or form the documents relate to, so the CRA can match them to your file. Your delivery confirmation is your proof that the fax was sent.
Fax the CRA From Outside Canada
FaxTerra runs entirely online, so where you are never matters — only the destination does. Canadian fax numbers are fully supported, so you can fax the CRA from the US, Europe, Asia, or anywhere else exactly as if you were in Canada. This is common for non-residents, newcomers, and Canadians abroad handling tax filings or responding to a CRA request from overseas.
Get the Reply: A Canadian Fax Number
If the CRA needs to fax something back, you need a fax number of your own. A FaxTerra subscription gives you a dedicated US or Canadian fax number that receives faxes straight to your inbox as PDFs — you're notified by email and on your phone the moment one arrives.

Frequently Asked Questions
What is the fax number for the CRA?
There is no single CRA fax number. The correct number depends on the form and the tax centre or program handling your file — it's listed on the CRA notice or form you received, or given to you by the CRA agent who requested the documents. Use that number, not a number from an unrelated letter.
Can I fax the CRA without a fax machine?
Yes. FaxTerra lets you fax the CRA online from your phone, tablet, or computer — no machine and no phone line. Upload your document, enter the CRA fax number, and send. Your first pages each month are free.
Is it free to fax the CRA?
Sending to Canadian numbers is included in every account's free monthly pages, so a short submission is typically free. Larger documents can use a credit pack, with no subscription required.
Can I fax the CRA from outside Canada?
Yes. Your location never blocks a fax — only the destination matters, and Canadian numbers are fully supported. You can fax the CRA from any country exactly as if you were in Canada.
How do I get a fax back from the CRA?
You need your own fax number. A FaxTerra subscription includes a dedicated US or Canadian fax number that receives faxes as PDFs by email, with notifications on your phone. Give that number to the CRA when they ask where to fax your documents.
Does the CRA confirm it received my fax?
Not usually — the CRA does not send automatic acknowledgments for most faxed documents. Your fax delivery confirmation is your evidence that the document was transmitted. Keep it with your records, and follow up through My Account or by phone if needed.
