CRA Place of Supply Rules: What Tax to Charge Out-of-Province Clients

Once you register for a GST/HST number, billing local clients is simple: you charge the sales tax rate of your home province. But what happens when an Ontario freelancer bills a client in British Columbia, Alberta, or the United States? To stay compliant, Canadian sole proprietors must master the CRA **Place of Supply** rules.

The Golden Rule

For professional services, the sales tax rate is determined by the **physical billing address of your client (the recipient)**, not your location. Your home province's tax rate does not follow your invoices across provincial borders.

1. Charging Sales Tax by Province

If you are registered for GST/HST and perform services for a client in another Canadian province, you must apply the sales tax rate of the recipient's province. Let's break down what to charge based on your client's billing address:

Client ProvinceTax TypeRate to Charge
AB, NT, NU, YTGST Only5%
BC, MB, QC, SKGST Only (for custom services)5%
Ontario (ON)HST13%
NB, NL, NS, PEHST15%

For example, if you are an Ontario freelancer (13% HST) billing a client in Calgary, Alberta, you charge only **5% GST** on their invoice. If you are a BC freelancer (5% GST) billing a client in Toronto, Ontario, you must charge **13% HST**.

2. US and International Clients: The Zero-Rated Rule

If you provide creative, technical, or consulting services to clients outside of Canada (such as a US startup or a UK agency), your services are classified as **zero-rated exports** (taxed at 0%).

3. What About Provincial PST (BC, SK, MB, QC)?

Sole proprietors are often terrified that they will have to register for provincial sales taxes (like BC PST, SK PST, MB RST, or QC QST) when billing out-of-province clients.

Fortunately, if you sell **custom professional services** (such as custom software development, custom graphic design, marketing consulting, or copywriting), provincial sales taxes **do not apply**. You are only required to collect the federal GST portion (5%).

The SaaS Exception

If your business sells pre-packaged software, digital downloads, or SaaS (Software-as-a-Service) subscriptions rather than custom services, provinces like BC, SK, and QC have specific digital tax rules. You may be required to register for their provincial PST/QST once your sales to their residents exceed $10,000.

4. Audits: The Importance of a Billing Address

If the CRA reviews your sales tax filings, they will want to see why you charged 5% GST to a client instead of your home province's 13% or 15% HST.

To satisfy an auditor, you must include the **recipient's physical business address** directly on the invoice. You cannot simply list a US or out-of-province name without their physical location — doing so can cause the CRA to deny the place-of-supply classification and retroactively charge you the difference out of your own pocket.
