Form W-8BEN tells a US client or platform that you are not a US person, so it doesn’t have to treat you like an American contractor or withhold US tax from your pay. As a Canadian freelancer working from Canada, you fill in Part I with your name, Canadian address and SIN, usually leave the treaty section blank or claim the Canada–US treaty’s business profits article, sign, and send it to the client – never to the IRS. Corporations use W-8BEN-E instead.
What Form W-8BEN is for
US businesses must document who they pay. For a US contractor they collect a W-9 and report the payments to the IRS. For a foreign contractor, they collect a W-8BEN, which certifies that you are a foreign person and, if needed, claims a reduced withholding rate under a tax treaty. Without it, a client may withhold 30% of certain payments or refuse to pay until the paperwork is in place.
The form stays with the client or platform as part of its records. You don’t file it with the IRS, and it doesn’t create a US tax return for you. Our guide to freelancing in Canada covers the Canadian side – registration, GST/HST and income tax.
W-8BEN, W-8BEN-E or W-9?
| Form | Who uses it | Canadian freelancer? |
|---|---|---|
| W-8BEN | Foreign individuals, including sole proprietors | Yes – if you invoice in your own name or as a sole proprietor |
| W-8BEN-E | Foreign entities (corporations, partnerships) | Yes – if you invoice through your own incorporated company |
| W-9 | US citizens, US residents and US companies | No – unless you are a US citizen or green card holder |
US citizens living in Canada are US persons for tax purposes and use a W-9, not a W-8BEN, even if they have lived in Canada for years. The same applies to green card holders.
How to fill in the W-8BEN, line by line
These line numbers follow the current form revision; download the form and instructions from irs.gov rather than using an old copy a client sends you.
Part I – Identification of beneficial owner
- Line 1 – Name: your legal name as an individual, even if you use a business name on invoices.
- Line 2 – Country of citizenship: your citizenship, e.g. Canada.
- Line 3 – Permanent residence address: your home address in Canada. Not a P.O. box and not a “care of” address.
- Line 4 – Mailing address: only if different from line 3.
- Line 5 – US taxpayer identification number: usually blank. Most Canadians have no SSN or ITIN and don’t need one for this.
- Line 6a – Foreign tax identifying number: your Canadian SIN. Line 6b is for people whose country doesn’t issue a tax number, which doesn’t apply to Canada.
- Line 7 – Reference number: optional; some clients put a vendor or account number here.
- Line 8 – Date of birth: in the format the form shows (MM-DD-YYYY).
Part II – Claim of tax treaty benefits
Whether you need Part II depends on where you do the work. Income for services you perform in Canada is not US-source income, so normally no US withholding applies to it at all. That’s why many Canadian freelancers leave Part II blank.
Some clients and platforms still ask you to complete it. In that case, line 9 is “Canada”, and on line 10 freelancers commonly cite Article VII (Business Profits) of the Canada–US tax treaty, a 0% rate, “business profits”, and the explanation that you have no permanent establishment in the United States. If you travel to the US to do work for the client, the situation changes – get advice before you sign.
Part III – Certification
Sign, date, and print your name. Many clients and platforms accept an electronic signature. Tick the box certifying that you have the capacity to sign for the person named on line 1 – when you sign for yourself, that is you.
No tax advice: this summarises the IRS form and the treaty’s general rule (checked November 2026). If you work partly in the US, hold US citizenship, or receive royalties or other non-service income, ask an accountant who knows cross-border tax.
How long it’s valid and when to send a new one
A W-8BEN generally stays valid until the end of the third calendar year after the year you sign it: a form signed in November 2026 is valid until December 31, 2029. Send a new one sooner if something on it changes – you move, become a US resident or citizen, or incorporate.
Is it safe to put my SIN on it?
Line 6a asks for your foreign tax number, so giving your SIN to a real client on this form is normal. The risk is a fake “client” collecting W-8BEN forms to steal identities. Before you send it:
- Make sure you have a real contract or accepted proposal with a business you’ve verified.
- Send it through the client’s vendor portal or the platform’s tax interview rather than as a plain email attachment where possible.
- Never send a W-8BEN together with your bank login, a photo of your ID and a selfie to someone you met in a chat app. If that has already happened, see what to do if you gave your SIN to a scammer.
Getting paid in US dollars
Once the paperwork is done, the cost of converting US dollars often matters more than any tax form. The common options:
| Method | How it works | Cost to watch |
|---|---|---|
| USD account at a Canadian bank | Client pays by wire or ACH-style transfer into your US-dollar account | Incoming wire fees; the bank’s exchange spread when you convert |
| Wise | You get US account details; the client pays like a domestic US transfer | A visible conversion fee at close to the mid-market rate |
| PayPal | Client pays to your email; widely accepted | Receiving fees for business payments and a currency conversion markup that is usually higher |
| Payoneer | Popular with freelance marketplaces | Fees on withdrawals and conversion; check the current schedule |
Fees change, so compare the amount that actually arrives in Canadian dollars for a typical invoice. Report the income on your Canadian return in Canadian dollars; the CRA accepts the Bank of Canada exchange rate for the day you were paid or the annual average rate.

Common questions
Do I have to fill out a W-8BEN as a Canadian?
Only if a US client or platform asks for it, which most do before the first payment. It’s the standard way to show you aren’t a US person.
Will the US tax my freelance income?
Not normally, if you do the work in Canada and have no fixed place of business in the US. You pay tax on it in Canada.
Do I need an ITIN?
For ordinary freelance services performed in Canada, usually not. Line 6a with your SIN identifies you.
Does a W-8BEN replace my Canadian tax return?
No. It’s a US form for the client’s records. You still report all freelance income on your Canadian return (form T2125).
