How to Fax the Canada Revenue Agency
Updated October 2026
The CRA sent you a letter asking for documents, and you want them there today rather than in the mail. Fax them to the number printed in that letter for $1.00 for up to 10 pages: Canadian fax numbers cost exactly the same as US numbers on FaxForADollar.
Quick answer: Use only the fax number in your CRA letter. The CRA does not publish one general fax number. For benefit and credit reviews you can fax, mail, or use Submit documents online in My Account. The Charities Directorate stopped receiving faxed documents as of April 1, 2026. FaxForADollar sends up to 10 pages to any Canadian number for $1.00.

Use the Fax Number in Your CRA Letter
The CRA does not publish a single fax number for the public. Each letter that asks for documents tells you where to send them, and for benefit and credit reviews the CRA lets you send documents by fax to the number provided in the letter. That number is the only one to use. Sending to any other CRA line risks your documents never reaching your review.
Before you send, find the reference number in the upper right corner of the letter. Write it on your cover page and on every page so your documents land in the right file.
Submit Documents Online Instead
If you have My Account, Submit documents online is the CRA's other fast route. You enter the reference number from the upper right corner of your letter and upload your files. The limits are 10 files and 150MB in total.
Fax is the better choice when you cannot sign in to My Account, when you are helping someone who has no account, or when you have paper receipts and only a phone to scan them with. Mail is the third option the CRA accepts, and the slowest.
Charities: Fax Is No Longer Accepted
As of April 1, 2026, the CRA's Charities Directorate stopped receiving faxed documents. If you run or volunteer for a registered charity, do not fax anything to the Charities Directorate. Check the CRA's charities pages for the current ways to send documents. This change applies to the Charities Directorate, not to benefit and credit reviews, which still accept fax to the number in your letter. For US exempt organizations, see our IRS exempt organizations guide.
Non-Resident Account Representative Authorization
One CRA fax number is published for a specific purpose: authorizing a representative on a non-resident account, using Form AUT-01 (which gives offline access only), goes to the Sudbury Tax Centre at 1-705-671-4559, and the CRA asks you to send the form within six months of signing it. On FaxForADollar, type it as 7056714559. If you also deal with the IRS, our Form 2848 and 8821 guide covers representative authorizations on the US side.
Number Format and Price
Canada uses the same +1 country code as the US and the same 10 digit format, so a CRA number works exactly like a US one. Type the area code and number, 10 digits, no leading 1. The +1 is already added.
Up to 10 pages is $1.00, which covers most review packets: a cover page, the CRA's letter and a few receipts or statements. 11 to 25 pages is $1.99 and 26 to 50 is $2.99. Nothing is printed on your document. There is no account. The fax is usually delivered within a few minutes, and the confirmation email shows the destination number, page count and time in Eastern Time, your record of exactly when it was sent. If the fax fails, you are refunded automatically.
If you also need to fax a number outside the US and Canada, our sister service OverseasFax.com starts at $2.99. Prefer instructions in French? Read our French guide to sending a fax online.
What to Put on the Cover Page and Every Page
The cover page should show your full name, the reference number from the upper right corner of the CRA letter, the date of the letter, a short list of what you are sending, the total page count, and a phone number. On every page, write your name and the reference number in the top margin. Put a copy of the CRA letter right behind the cover page.
Scan receipts flat and in good light so totals and dates are readable. Our iPhone faxing guide shows how to turn phone photos into clean pages.
