Home › Blog › ITIN for Canadian Amazon Sellers: Sell on Amazon.com From Canada | ITIN Plus

Canadian entrepreneurs are among the most active Amazon.com sellers outside the US. But selling on Amazon.com (the US marketplace) has tax compliance requirements that Canadians must address. An ITIN is essential for completing Amazon's tax interview and avoiding 30% withholding on your US sales.

Amazon.com vs Amazon.ca: The Tax Difference

Selling on Amazon.ca (Canada) has minimal US tax implications. But selling on Amazon.com (the US marketplace) means your earnings come from US buyers — making them US-source income subject to IRS reporting.

Amazon's tax interview for Amazon.com sellers requires a W-8BEN (for non-US individual sellers) or W-8BEN-E (for entities) with your Tax ID. Without completing this, Amazon withholds 30% of your US earnings before deposit.

The Canada-US Treaty on Amazon Royalties

If you sell your own brand products on Amazon (not just retail arbitrage), some income categories may qualify for reduced withholding under the Canada-US Tax Treaty. Your ITIN enables you to claim treaty benefits on your W-8BEN, potentially reducing withholding on royalty-type income from zero to a significantly reduced rate.

Professional Amazon Seller Setup from Canada

Most serious Canadian Amazon.com sellers operate through a US LLC:

This setup gives you full Amazon.com access, US payment processing, and proper tax documentation.

Frequently Asked Questions

Do Canadian Amazon sellers need an ITIN to sell on Amazon.com?
Yes. Amazon requires a W-8BEN (for individual sellers) or W-8BEN-E (for entity sellers) with your Tax ID for Amazon.com. Without an ITIN, Amazon withholds 30% from your US sales proceeds.
Can Canadian sellers sell on both Amazon.com and Amazon.ca?
Yes. Many Canadian sellers are active on both marketplaces. Amazon.ca earnings have fewer US tax implications, while Amazon.com earnings require a W-8BEN with your ITIN.
Do I need a US LLC to sell on Amazon.com from Canada?
No, you can sell as an individual with just an ITIN. However, a US LLC provides access to US payment processing, better business structure, and potentially simplified tax treatment.
How long does it take to get an ITIN?
8–14 weeks from the IRS submission date. ITIN Plus handles the complete process for $99.
What is the Canada-US Tax Treaty rate on Amazon earnings?
It varies by income type. For royalty-type income, the Canada-US Treaty can reduce withholding from 30% to 0–10%. For sales proceeds (not royalties), the treaty treatment differs. ITIN Plus selects the correct treaty position for your specific income type.
