Cross-border tax for translation and interpretation firms
US agency and corporate clients are usually the easy part — zero-rated at home, treaty-protected in the US once a W-8BEN-E is on file. The real cross-border complexity sits on the cost side, paying a freelancer bench scattered across the US and overseas, and in the one scenario that catches firms off guard: flying a foreign interpreter into Canada for an assignment.

Billing US clients: zero-rated, treaty-covered
A translation or localization project billed to a US agency or corporate client, delivered remotely, is a zero-rated export for GST/HST — invoice at 0%, keep every input tax credit on Canadian costs. On the US side, the treaty's business-profits protection means no US federal tax without a permanent establishment, and a completed W-8BEN-E on file with the client keeps their accounts payable system from withholding defensively. That protection assumes the work is genuinely remote; a project that puts staff physically on-site in the US, or an interpreter working an in-person US assignment, moves into different territory that deserves its own look.
A US client's own accounts payable system is often the practical trigger, not CRA or the IRS — many US corporations default to withholding 30% on any foreign payee unless a valid W-8BEN-E is already on file, so getting the form in place before the first invoice, not after a payment arrives short, saves a recovery filing later.
A master services agreement with a larger US client sometimes bundles several project types into one relationship — translation, localization QA, even light consulting on terminology. Reviewing the contract language before signing helps confirm the whole relationship stays inside the services characterization rather than drifting into something a US payer's tax department reads differently.
Paying the freelancer bench: forms follow the person
A Canadian payer generally has no obligation to collect W-9 or W-8 forms from freelancers the way a US payer must — those obligations sit with the US side, not us. Even so, keeping a light file is worth the effort: a Canadian-resident freelancer gets a T4A once their fees cross the reporting threshold, while a freelancer working from home in the US or overseas triggers no Canadian slip and no withholding at all, because the service happens entirely outside Canada.
Some freelancers, especially those working through their own US LLC or corporation, will ask for a W-9 or a W-8 anyway out of habit from working with US clients. There's no harm in accommodating that request, but it doesn't change any Canadian filing obligation on our side of the payment.
The trip wire: flying an interpreter into Canada
The scenario that most reliably catches language firms off guard is bringing a non-resident interpreter into Canada in person — for a conference, a deposition, a high-profile hearing. That triggers Regulation 105: 15% withheld from the fee and a T4A-NR issued, regardless of where the interpreter normally lives or works, unless a waiver is approved by CRA before the payment goes out. It's the same rule that catches law firms and marketing agencies bringing in foreign talent, but interpreting work is one of the more common ways a language firm actually runs into it.
| Payment scenario | GST/HST or withholding | What to keep on file |
|---|---|---|
| Billing a US client for remote translation | Zero-rated export | A W-8BEN-E given to the client to stop default withholding |
| Paying a freelancer working from home abroad | No Canadian slip or withholding | Basic invoice records for the job file |
| Paying a Canadian-resident freelancer | T4A once fees cross the reporting threshold | HST registration status if claiming an ITC |
| Flying a foreign interpreter into Canada | Reg 105: 15% withheld, T4A-NR issued | A waiver application filed with CRA before payment |
Keeping USD and EUR receivables straight
Multi-currency invoicing should convert at the rate on the invoice date, with the FX gain or loss landing on the P&L rather than in a suspense account nobody reconciles. Zero-rated exports still have to appear on the GST/HST return even though the rate charged is nil — leaving them off the return entirely is a filing error, not a simplification. Our bookkeeping page covers how we tie job-level currency and margin data together month to month.
None of this requires a US entity for a firm doing genuinely remote work. A US LLC or corporation only becomes worth discussing once a firm considers putting staff physically in the US or taking on a US-based partner, and that's a separate conversation from ordinary cross-border billing — one we'd rather have when the facts actually call for it than sell in advance.

Common questions.
Do we charge GST/HST on translation work for a US-based client?
Generally no — remote translation and localization delivered to a non-resident client is a zero-rated export, so you bill at 0% and still recover input tax credits on your Canadian costs.
Do we need to collect tax forms from our overseas freelancers?
Not as a Canadian payer — that obligation sits with US payers, not us. We still recommend a light file for each freelancer, since a Canadian-resident freelancer needs a T4A while a freelancer working abroad needs neither a slip nor withholding.
What happens if we fly a foreign interpreter into Canada for a job?
Regulation 105 applies: 15% of the fee gets withheld and a T4A-NR issued, unless a waiver is approved by CRA before you pay. It applies regardless of where the interpreter normally works.
