How to Invoice US Clients from Canada (W-8BEN, USD, Zero-Rated HST)

Why the US Client Workflow Is Different

For Canadian clients, your invoicing workflow is well-defined: collect HST at the client's provincial rate, follow Canadian payment-term conventions, get paid in CAD. For US clients, three things change:

• Tax paperwork. US clients typically require a W-8BEN form before they can issue you payment. Skipping this triggers a 30% US tax withholding under default IRS rules.
• Currency. Most US clients expect to pay in USD. You handle the FX conversion to CAD when the money lands, and you record the CAD-equivalent for Canadian tax purposes.
• AP cycles. Enterprise US clients often pay net 60–90 days even when your invoice says net 30. Vendor onboarding alone can add 30 days before the first cheque.

The Tax Picture in 30 Seconds

The four facts that govern almost every Canadian-to-US freelance situation:

1. Services to US clients are zero-rated supplies for GST/HST purposes. Taxable at 0%, not exempt. Your invoice still shows an HST line at 0% — documenting that you considered the tax and correctly determined it doesn't apply.
2. You'll usually need to complete a W-8BEN (or W-8BEN-E for incorporated businesses). This goes to the client, not the IRS. It claims Canada-US tax treaty benefits and prevents the default 30% US withholding.
3. You generally owe no US income tax as long as you don't have a "permanent establishment" in the US (no US office, no US employees, limited on-site presence). The Canada-US tax treaty exempts your business income from US tax under these conditions.
4. Your income is still fully taxable in Canada. US-client revenue lands on T2125 Line 8000 just like Canadian revenue, converted to CAD using the Bank of Canada exchange rate. See our T2125 form guide.

W-8BEN — The Form Almost Every US Client Will Ask For

W-8BEN is a US IRS form that confirms two things to a US payer: (1) you are not a US person for tax purposes, and (2) you are entitled to claim treaty benefits that reduce or eliminate US withholding tax on payments to you.

What It Does in Practice

Under default IRS rules, a US payer must withhold 30% of payments to foreign persons as US income tax. If you receive a $5,000 invoice payment with no W-8BEN on file, $1,500 is withheld at source and remitted to the IRS — you receive $3,500. To get the withheld $1,500 back, you'd file a US tax return (Form 1040-NR) the following year and wait for an IRS refund. The process takes months.

With a valid W-8BEN on file with the client, no withholding applies. You receive the full $5,000.

W-8BEN vs W-8BEN-E

• W-8BEN — for individuals. Use this if you operate as a sole proprietor.
• W-8BEN-E — for entities (corporations, partnerships, trusts). Use this if you've incorporated and the invoice is from your corporation.

Completing It (10 Minutes)

The form has roughly three sections to focus on:

• Part 1 — your identification: legal name, country of citizenship (Canada), permanent residence address (Canadian address), mailing address if different. You can leave the US Taxpayer Identification Number field blank if you don't have one (you usually don't and don't need one).
• Part 2 — claim of treaty benefits: select "Canada" as the country of tax residence, reference the relevant article of the Canada-US tax treaty (Article VII for business profits is the most common), and confirm you meet the conditions for treaty relief.
• Sign and date. Your signature.

Validity

A W-8BEN is valid for the year signed plus the three following calendar years. So a form signed in 2026 is valid through 2029. After expiry, the client will ask you to submit a fresh one. Many US clients track this themselves and prompt you proactively; some don't.

Provide It Proactively

When onboarding with a new US client, ask up front: "Should I send you a W-8BEN with my first invoice?" Smaller US clients may not realize they should be asking, and a missing W-8BEN can hold up your first payment by weeks while their AP system flags it.

Currency: Invoice in USD or CAD?

The default rule: invoice in whatever currency the contract specifies. For US clients, this is almost always USD.

Why USD Is the Default

• US client AP systems expect USD; processing CAD invoices may require manual workarounds
• The contract is usually negotiated and signed in USD
• Cheques, ACH transfers, and wire instructions on the US side are USD-native

The FX Risk Question

Invoicing in USD means you bear the foreign-exchange risk. If you sign a $5,000 USD contract at 1 USD = 1.36 CAD ($6,800 CAD equivalent), and three months later the rate is 1.32 ($6,600 CAD), you receive $200 less in CAD than you expected. The reverse can also happen — if CAD weakens, you receive more.

Most Canadian freelancers accept this risk as the cost of working with US clients. For larger contracts or multi-month engagements, you can negotiate currency-clauses (re-pricing in CAD at quarterly intervals) but most clients won't agree.

When to Invoice in CAD

Only when the contract explicitly says so. Some smaller US clients (especially those that hire a lot of Canadians) are happy to pay in CAD. If that's the arrangement, invoice in CAD; the client handles the FX on their side.

Exchange Rate Documentation for the CRA

Even when you invoice in USD, your Canadian tax obligation is in CAD. The CRA expects you to convert your USD revenue to CAD using an acceptable exchange rate methodology.

Use the Bank of Canada Exchange Rate

The Bank of Canada publishes daily exchange rates (12-month averages, monthly averages, and daily noon-rate equivalents). This is the CRA's preferred reference. Other sources (Google's FX widget, your bank's rate, OANDA) may be slightly different and create reconciliation issues if used inconsistently.

Two Methods, Pick One and Be Consistent

• Transaction-date rate. Convert each USD invoice to CAD using the Bank of Canada rate on the date the invoice was issued (or paid — be consistent about which). More accurate, more record-keeping.
• Annual average rate. Convert all USD revenue for the year using the Bank of Canada annual average rate. Less accurate, less record-keeping. Acceptable if your USD income is small or volatile.

Most freelancers with regular US revenue use the transaction-date method because it matches the actual CAD received. Either is defensible if applied consistently.

Recording in Your Books

For every USD invoice, record both the USD amount and the CAD equivalent. When the payment lands and you convert (or your bank does), record the actual CAD received as well. Any difference between "expected CAD at invoice date" and "actual CAD at payment date" is an FX gain or loss, which can be claimed (or reported) at year-end. For most freelancers these amounts are small and washed into other expenses.

Receiving Payment from US Clients (Five Options Compared)

For ongoing US revenue, the most common combination among Canadian freelancers is: receive via Wise or a USD account at a Canadian bank, hold USD if you have any USD expenses, convert to CAD when needed. Combined fees and FX spread on a $5,000 payment can range from ~$25 (Wise) to ~$200 (international wire + poor bank FX), so the channel matters.

The Zero-Rated Supply Mechanic on Your Invoice

Services exported outside Canada are zero-rated supplies under the Excise Tax Act. Zero-rated is different from exempt: zero-rated supplies are taxable, just at a 0% rate. The distinction matters because zero-rated suppliers can still claim Input Tax Credits on related business expenses (exempt suppliers cannot).

How It Should Appear on the Invoice

Show the HST line explicitly at 0%:

Showing the 0% line is stronger than silently omitting HST — it documents that you considered the tax treatment and correctly applied it. In a CRA review, this is the difference between "the freelancer understood the rule" and "the freelancer forgot to charge HST."

Supporting Documentation

The zero-rating depends on the client being outside Canada and the service being used outside Canada. Practically, this is satisfied by:

• Client billing address in the United States (on the invoice)
• Services delivered electronically to a US recipient, or work performed remotely from Canada for use in the US
• Contract or scope of work documenting the US-based use of the deliverable

For the broader Canadian GST/HST framework that this zero-rating sits within, see our GST and HST rules for Canadian freelancers.

US Client AP Cycle Realities

Three patterns to expect:

Enterprise US Clients (1,000+ Employees)

Net 30 on the invoice often means net 60–90 in practice. Their AP systems run on fixed cycles, vendor onboarding takes weeks, and first payments can take 45–60 days even after the invoice is technically due. Build this into your cash flow planning. Avoid having more than a couple of enterprise US clients with no Canadian or smaller-client income to bridge the gaps.

Mid-Market US Clients (50–1,000 Employees)

Closer to Canadian SMB behaviour — net 30 actually pays in 30–45 days. Standard W-8BEN and PO process; otherwise unremarkable.

Small US Businesses and Startups

Often pay fast (net 7–15) because there's no formal AP department — the founder or operator pays invoices personally. May skip W-8BEN entirely (don't know about it). May pay via personal Venmo (which doesn't work for Canadian recipients) or PayPal.

The Vendor Onboarding Delay

For mid-to-large US clients, expect a vendor-onboarding step before your first invoice can be paid. This involves submitting:

• W-8BEN
• Banking details (ACH instructions for a Canadian USD account, or international wire instructions)
• A signed vendor agreement or NDA
• Sometimes additional compliance documents (anti-bribery, security questionnaires)

This step typically takes 2–4 weeks. Plan for your first invoice to be paid roughly 30 days later than a Canadian first invoice would be.

Permanent Establishment (PE) Risk — When You Might Owe US Tax

The Canada-US tax treaty exempts a Canadian resident's business income from US tax as long as the Canadian doesn't have a "permanent establishment" in the US. For most freelancers, this is straightforward: no US office, no US employees, no US-stored equipment — no PE, no US tax.

Risk Factors That Can Create PE

• Extended on-site work at a US client's office (especially over many months)
• Renting or maintaining a US office space
• Hiring US-based employees or sub-contractors
• Storing significant business equipment in the US
• Having a "fixed place of business" in the US that's available to you regularly

If any of these apply to your situation, PE may be triggered and US tax obligations may follow. The Canada-US treaty has specific rules around what counts; a cross-border accountant or tax lawyer should review your situation before you assume anything. This is one of the few areas where DIY tax research is genuinely insufficient.

Common Mistakes

1. Charging HST to a US Client

The most common cross-border error. Services to US clients are zero-rated; HST should appear at 0%, not at 13% or any Canadian provincial rate. Charging HST and remitting it to the CRA is a hassle to unwind — you'll need to refund the client and adjust your HST return.

2. Refusing or Delaying W-8BEN

Some freelancers don't understand W-8BEN and either ignore the request or push back. The result: the client withholds 30% under US default rules, you receive 70% of your invoice, and recovering the rest requires a US tax filing. Just complete the form — it takes 10 minutes.

3. Invoicing in CAD When the Client Expects USD

Surprises the client's AP system, may require manual processing, often delays first payment. Match the contract currency; if it's USD, invoice in USD.

4. Using a Google FX Rate Instead of Bank of Canada

Google's FX widget shows the mid-market rate at a moment in time — not the Bank of Canada's published rate the CRA expects. For Canadian tax purposes, use Bank of Canada exclusively.

5. Not Recording CAD-Equivalent Income for T2125

Your USD revenue must be converted to CAD before it lands on T2125 Line 8000. Recording only the USD amount means you reconstruct CAD at tax time using whatever rate you happen to remember — inaccurate and inconsistent. Record both at invoice time.

6. Treating PayPal/Stripe Fees as Tax-Deductible Income Reductions

PayPal and Stripe fees are bank charges (Line 8710) — they're a separate expense on T2125, not a reduction of gross sales. Report the full invoice amount as income on Line 8000, and the fees as a separate expense. Netting the fee into sales understates income for tax purposes and creates reconciliation issues.

Frequently Asked Questions

Do I charge HST to US clients?

No. Services to US clients are zero-rated supplies — taxable at 0%. Show the HST line at 0% on the invoice with a note ("export of services, zero-rated") to document the treatment.

Do I need to complete a W-8BEN?

Almost always for formal US clients. Without it, the client may withhold 30% US tax under default IRS rules. With it, no withholding applies. The form goes to the client, not the IRS, and is valid for the year signed plus three calendar years.

Should I invoice US clients in USD or CAD?

Invoice in whatever currency the contract specifies — almost always USD. You bear the FX risk, which is convention. Some smaller US clients will agree to CAD if the contract says so.

Will I get a 1099 from a US client?

Generally no — Canadian contractors fall outside the US 1099-NEC reporting regime when there is no US permanent establishment. If a US client withheld tax (because no W-8BEN was on file), they may issue Form 1042-S instead, which can be used to claim a US refund via 1040-NR.

Do I report US-client income on my Canadian tax return?

Yes — all worldwide income for Canadian residents is reported on the Canadian return. USD revenue is converted to CAD at the Bank of Canada rate and lands on T2125 Line 8000 just like Canadian-client revenue. See our T2125 form guide.
