Canadian authors publishing on Amazon Kindle Direct Publishing (KDP) have a major advantage over most international authors: the Canada-US Tax Treaty reduces royalty withholding from 30% to 0% for Canadians. But you need an ITIN to claim this benefit. Without it, Amazon withholds the full 30%.
The Canada-US Tax Treaty on KDP Royalties
Amazon KDP pays royalties for book sales. Under the Canada-US Tax Treaty (specifically Article XII — Royalties), royalties paid from the US to Canadian residents are subject to 0% US withholding. This is one of the best treaty provisions for Canadian authors — you keep 100% of your KDP royalties instead of losing 30%.
To claim this 0% rate, you must provide your ITIN via Amazon's tax interview and explicitly claim the treaty benefit in the W-8BEN form.
How to Complete Amazon's Tax Interview as a Canadian
In KDP account settings:
- Go to Account → Tax Information → Interview
- Select 'Individual' and 'Non-US person'
- Select Canada as your country of residence
- Enter your ITIN
- In Part III (Treaty Benefits): Enter Canada as the country, Article XII (Royalties), 0% rate
- Sign and submit
Amazon processes the treaty claim and applies 0% withholding to your royalties. This takes effect for the next royalty payment cycle.
Potential Annual Savings for Canadian KDP Authors
If you earn $2,000/month in KDP royalties: Without ITIN = $600/month withheld (30%). With ITIN + Treaty = $0 withheld (0%). Annual savings: $7,200. Your $99 ITIN pays for itself within a few days of your first full royalty payment.

Frequently Asked Questions
What is the Canada-US Tax Treaty rate on KDP royalties?
Under Article XII of the Canada-US Tax Convention, royalties paid from the US to Canadian residents are subject to 0% US withholding. This means Canadian KDP authors keep 100% of their book royalties when they claim this treaty benefit.
How do I claim the 0% treaty rate on Amazon KDP?
Complete Amazon's tax interview (Account → Tax Information → Interview), select Canada as your country, enter your ITIN, and in Part III claim treaty benefits under Article XII at 0% rate. Amazon applies 0% withholding to future royalty payments.
Do I need an ITIN to publish on Amazon KDP as a Canadian?
You can publish without an ITIN, but Amazon will withhold 30% of your royalties. An ITIN + treaty claim eliminates this withholding completely for Canadian authors.
How long does it take to get an ITIN?
8–14 weeks from the IRS submission date. Apply through ITIN Plus for $99.
What if I've already had royalties withheld without an ITIN?
You may be able to file a US tax return (Form 1040-NR) to recover previously withheld taxes. Consult a US CPA for your specific situation. Going forward, your ITIN and treaty claim will stop future withholding.
