Your first big Amazon Associates or ClickBank payout lands, in US dollars, and you wonder what the Canada Revenue Agency expects. The short version: affiliate income is taxable from the first dollar, and the GST/HST and US-network rules trip up almost everyone. Here is how it works.
General 2026 guidance for Canadian affiliate marketers. GST/HST thresholds and tax rates can change, so confirm your situation against current CRA guidance before you file.
Key takeaways
- Affiliate commissions are business income, taxable from the first dollar, and reported on Form T2125 with your personal T1 return.
- Convert every US-dollar payout to Canadian dollars using the Bank of Canada exchange rate, and keep a record.
- The $30,000 GST/HST threshold is based on worldwide taxable sales, and your zero-rated US income still counts toward it.
- Once registered, you charge 13% HST to Canadian payers and 0% to US networks, but you can claim input tax credits either way.
- You are taxed only on net profit, so track expenses and hold your records for six years.
Is affiliate marketing income taxable in Canada?
Yes. If you earn commissions from affiliate links, the Canada Revenue Agency treats that money as business income. It is taxable from the first dollar you make. There is no minimum amount you can earn before you have to report it.
This catches people off guard. The $30,000 figure you may have heard about is a GST/HST registration threshold, not an income reporting threshold. They are two separate rules. You report all of your affiliate income on your tax return no matter how small, and GST/HST is a different question we cover below.
Whether you earn $200 a month or $10,000 a month, the tax treatment is the same. It is all reportable business income. The CRA also expects you to report non-cash perks, so a free product or a paid trip you receive in exchange for promotion counts as income at its fair market value.
Affiliate income counts as self-employed business income
When you earn affiliate commissions, the CRA considers you self-employed. You are a sole proprietor by default, which means you and your business are the same person for tax purposes. You report the income on Form T2125, the statement of business activities that attaches to your personal T1 return.
The CRA has been clear that people who earn money online, including social media influencers and affiliate marketers, carry on a business when there is an element of profit. Your affiliate site, your email list and your content are all part of that business. You do not need a registered company or a business name for this to apply. The moment you earn commission with the intention of making money, you have business income to report.
How to report affiliate marketing income on your tax return
Here is the practical sequence for filing taxes on affiliate income.
- Track every payout. Save the statements from each network (Amazon Associates, ShareASale, Impact, ClickBank and any others) and your matching bank deposits.
- Convert each payout to Canadian dollars (see the next section).
- Total your income and your business expenses on Form T2125.
- The net profit flows to line 26000 of your T1 return and is taxed at your personal marginal rate.
- Pay any balance owing by April 30. If you are self-employed, your filing deadline is June 15, but the CRA still charges interest on tax owing after April 30.
That last point trips up a lot of affiliates. The later June 15 filing date does not give you extra time to pay. Set money aside through the year so April 30 is not a problem. If you would rather hand the filing off, this is exactly the personal and business tax work a CPA handles.
Converting US-dollar affiliate payouts to Canadian dollars
Most affiliate networks pay in US dollars. You report income in Canadian dollars, so every payout needs to be converted.
The CRA accepts the Bank of Canada exchange rate. You can use the daily rate on the date each payment was made, or the annual average rate for income that arrives regularly through the year. Pick one method and stay consistent.
Keep a simple spreadsheet: date, US amount, exchange rate, Canadian amount. If the CRA ever asks how you arrived at your reported income, that record answers the question in seconds.
Do you charge GST/HST on affiliate income?
This is where affiliate marketers get the most confused, and the answer depends entirely on who is paying you.
GST/HST is a sales tax you collect for the government once you are registered. You have to register for GST/HST once your worldwide taxable sales pass $30,000 over four consecutive calendar quarters, or in a single quarter. Below that, you are a small supplier and you do not have to register or charge anything.
Once you cross $30,000, who you charge depends on where your network or merchant is located. If the company paying you is in Canada, your promotional service is taxable, and once registered you charge GST/HST on your invoices. In Ontario that is 13% HST. If the company paying you is outside Canada, for example a US affiliate network, your service is generally a zero-rated export, so you charge 0% and collect nothing extra from them.
Here is the part almost everyone misses. Zero-rated sales are still taxable sales, so they still count toward your $30,000 threshold. A Canadian affiliate earning $50,000 a year entirely from US networks has crossed the threshold and has to register for GST/HST, even though every sale is charged at 0%. You register, you file returns, and you remit nothing on that foreign income. The upside is real: once registered, you can claim back the GST/HST you paid on your own business expenses through input tax credits.
GST/HST on affiliate income, by who pays you
| Who pays you | Do you charge HST? | Counts toward $30,000? | If over $30,000 |
|---|---|---|---|
| Canadian network or merchant | Yes, 13% in Ontario once registered | Yes | Register and remit the HST you collect |
| US or other foreign network | No, zero-rated at 0% | Yes | Register, file returns, remit nothing on that income |
| Mix of Canadian and foreign | HST on the Canadian portion only | Yes, all of it | Register once the combined total is over $30,000 |
The $30,000 GST/HST threshold, explained
The threshold is based on your worldwide taxable sales, not your profit and not only your Canadian sales. Add up everything: Canadian commissions, US commissions and any other self-employed income from taxable activities.
You measure it two ways, and either one triggers registration. The first is more than $30,000 in a single calendar quarter. The second is more than $30,000 across the last four consecutive calendar quarters.
Once you go over, you have 29 days to register. After that you charge HST on your Canadian-sourced taxable sales and file GST/HST returns on the schedule the CRA assigns you. Many small affiliates register voluntarily before they hit $30,000 specifically to claim input tax credits on hosting, software and ad spend. Whether that makes sense depends on how much HST you are paying on expenses versus the filing work it adds.
What affiliate marketers can deduct
You only pay tax on your net profit, so tracking expenses is money in your pocket. The test is simple: the expense has to be reasonable and incurred to earn your affiliate income. If something is part personal and part business, you deduct only the business portion.
Common deductions for an affiliate business:
- Web hosting, domain names and your email platform.
- Software and tools such as SEO platforms, design apps and link trackers.
- Paid advertising you run to drive traffic.
- Fees paid to writers, editors or virtual assistants.
- A share of your phone and internet based on business use.
- Business-use-of-home expenses for a dedicated work space, though these cannot create or increase a business loss.
Keep the receipts. The CRA expects you to hold supporting records for six years.
Affiliate income from US networks: withholding and tax treaties
Affiliate commissions are payment for a service, so US networks usually do not withhold US tax the way they would on a royalty. Most Canadian affiliates receive their full commission and report it as Canadian business income.
Some US networks ask you to complete Form W-8BEN. This form certifies that you are a non-US person and claims your benefits under the Canada and US tax treaty. Filling it out correctly is what stops a US network from holding back tax it does not need to.
If a US payer ever does withhold US tax, you do not lose that money. You claim it as a foreign tax credit on your Canadian return using Form T2209, which reduces your Canadian tax dollar for dollar rather than acting as a simple deduction. This comes up far more often for YouTube and ad revenue than for affiliate commissions. We cover the W-8BEN and withholding mechanics in our article on why Google withholds 30% of YouTube income.
Should you incorporate your affiliate business?
Most affiliate marketers start as sole proprietors and stay that way for a while. Incorporation becomes worth considering once your business is consistently profitable and you do not need every dollar personally, because a corporation lets you defer tax on the profit you leave inside it.
It is not automatically better. A corporation adds accounting cost and filing work, and the tax savings only show up at certain profit levels. If your affiliate income has grown past roughly $80,000 of profit and you can leave a chunk of it in the business, it is worth a conversation. We walk through the full decision, including a trap that catches creators with a single main income source, in our guide on whether content creators should incorporate.
A worked example: a Whitby affiliate marketer
Worked example: $58,000 across US and Canadian networks
- Maya runs a product-review site from Whitby and earns from three US networks and one Canadian software company. In 2026 she collects $58,000: about $52,000 from the US networks and $6,000 from the Canadian company.
- On income tax, all $58,000 is business income. After $11,000 of expenses, her net profit is $47,000, which flows to her T1 return and is taxed at her personal rate.
- On GST/HST, her worldwide taxable sales of $58,000 are over $30,000, so she has to register. She charges 13% HST on the $6,000 from the Canadian company and 0% on the $52,000 from the US networks, but that foreign income still counted toward the threshold.
- Once registered, she claims input tax credits on the HST built into her hosting, software and ad spend, which puts a few hundred dollars back in her pocket.
- The lesson: the foreign income was not taxed by the GST/HST system, but it is what pushed her over the registration line.
Common mistakes that cost affiliate marketers at tax time
- Treating affiliate income as a hobby and skipping the small commissions. Unreported business income is the most common reason online earners get reassessed.
- Forgetting that foreign income counts toward the $30,000 GST/HST threshold.
- Charging 13% HST to a US network by mistake. Foreign B2B services are zero-rated, so adding HST is the wrong move and creates a mess to unwind.
- Reporting US payouts at the wrong exchange rate, or switching methods partway through the year.
- Not setting money aside, then getting surprised by a tax bill on April 30 and quarterly instalments the year after (the CRA requires instalments once your net tax owing tops $3,000).
