AI-generated imageWhy affiliate platforms ask for tax forms
Many US affiliate networks and programs pay commissions to people around the world. For US tax rules, those platforms may need to know whether you are a US taxpayer and how much tax to withhold from your payments.
Amazon Associates can withhold up to 30% of US-source commissions, the pay for promotion done in the United States. A payer that cannot document you as foreign may instead apply 24% backup withholding.
Form W-8BEN tells the payer you are a foreign individual. Commissions for promotion done outside the United States are not US-source, so Part II stays blank. An individual claims a treaty exemption for pay for work done in the United States on Form 8233, not on Form W-8BEN.

Sample: Callum Rees's W-8BEN for Amazon Associates
Callum's UK UTR is on line 6a. Part II is blank: commissions for affiliate work done outside the United States are not US-source income.
Example only. Callum Rees, 30 Granby Street, Leicester LE1 1DE, is fictional.
What type of income is affiliate income?
Affiliate income is usually commission-based: you earn when someone buys or signs up through your link, depending on the program’s rules.
How it is treated for tax purposes can vary. Some arrangements look more like fees for services or marketing; others may be closer to business or self-employment income. The right label depends on your facts, the network’s terms, and the treaty between the US and your country.
Our wizard helps you describe your income clearly. For complex cases, a qualified tax professional can confirm how your income should be reported.
Worked example: commissions for work done in Leicester need no treaty claim
Callum Rees runs a comparison-and-review site out of Leicester and earns commissions through ClickBank and Amazon Associates. When he first opened a W-8BEN tax interview, he was about to fill in Part II with an article and a rate, because he assumed every foreign affiliate had to claim one.
He did not need one. Commissions are pay for personal services, and IRS Publication 515 sources that pay where the services are performed. Callum does all his work in the United Kingdom, so his commissions are not US-source: there is no US withholding to reduce, and Part II stays blank, as on the sample on this page. The form still certifies that he is a foreign person, with his UTR on line 6a.
- Work done in the UK: Form W-8BEN with Part II blank, no article and no rate.
- Work done while he is in the United States: that pay is US-source, and an individual claims a treaty exemption for it on Form 8233, not on Form W-8BEN (IRS Publication 515).
What goes on the W-8BEN for Amazon Associates
- Line 6a: your UK Unique Taxpayer Reference (10 digits). Google and other payers also accept a National Insurance number.
- Part II: affiliate work done outside the US leaves Part II blank. If Amazon insists and the work was done in the US, a UK resident uses Form 8233 and Article 7.
- Amazon Associates collects it through its tax interview.
Your affiliate networks won't send you a domestic income summary — that's still on you
A W-8BEN only tells ClickBank, CJ, or any other US-based network how much US tax to withhold from your commissions — it has nothing to do with how you report that same income at home. Foreign affiliates don't receive a Form 1099 (that's a US-person information return), so nothing arrives automatically to summarize what you earned across a tax year.
For someone like Callum, running review sites and promoting through several networks at once, that means pulling commission totals from each network's own dashboard or CSV export and reconciling them himself before filing his UK Self Assessment with HMRC as self-employment income — the W-8BEN affects only the US withholding step, not what he ultimately owes on his UK return.
- Export commission statements from every affiliate network you use — don't rely on one network's numbers to represent your total affiliate income.
- Report the income at home under your normal self-employment or sole-trader rules, regardless of what (if anything) was withheld in the US.
- Keep the W-8BEN and network payout records together — they explain the gap between gross commissions and what actually landed in your account.

Affiliate marketing & W-8BEN FAQ
Do affiliate marketers need a W-8BEN?
Yes, when a US program pays you. Amazon Associates, for example, has every non-US associate complete its tax interview (Account Settings › View/Provide Tax Information › Take Interview), and the W-8BEN it collects shows that you are a foreign person. A program run by a non-US company has no reason to ask for a US form.
Does ClickBank or CJ withhold US tax?
Only on US-source payments, such as commissions for work done in the United States. A valid W-8BEN, given when asked, shows them that you are a foreign person, so they do not apply 24% backup withholding.
What tax applies to affiliate income?
Commissions for promotion you do from outside the US are personal-service income, sourced where the work is performed, so they are not US-source and carry no US withholding: Part II of the W-8BEN stays blank. Pay for work you do while in the United States is US-source, and an individual claims a treaty exemption for it on Form 8233, not on Form W-8BEN. At home, commissions are ordinary business or self-employment income.
Is affiliate income US-source income?
Only the part earned for work done in the United States. Commissions are pay for personal services, which IRS Publication 515 sources where the services are performed, whoever pays them. The wizard asks where you do the work and leaves Part II blank when you do it outside the US.
Can I reduce withholding with a treaty?
Not on commissions for work done outside the US: they carry no US withholding to reduce. For work done in the United States, an individual claims the treaty exemption on Form 8233. Part II of the W-8BEN is for other US-source income, such as royalties, when the treaty lowers the rate.
Do I need an ITIN?
Not everyone needs an ITIN or SSN to file W-8BEN. Some treaty claims work with a foreign tax identification number. The form instructions and your program’s prompts explain what applies to you.
