DO I NEED TO CHARGE GST/QST ON U.S. OR INTERNATIONAL SALES

If you sell goods or services to clients outside Canada — especially in the U.S. — you may wonder whether GST or QST applies. The rules vary depending on the type of product, whether you’re selling goods or services, and where the customer is located or consuming the supply. Many Quebec businesses make costly errors by charging GST/QST when they shouldn’t, or by failing to zero-rate legitimate exports. This guide explains when GST and QST apply to international sales and how to handle cross-border transactions properly.
Understanding international tax rules ensures correct invoicing, avoids disputes with global clients, and protects your business from reassessment.
LEGAL AND REGULATORY FRAMEWORK
Rules for international sales are governed by:
• the Excise Tax Act (GST)
• the Quebec Taxation Act (QST)
• place-of-supply regulations
• export provisions for goods and services
Under these rules:
• some supplies to foreign customers are zero-rated (0% GST/QST)
• some services are taxable depending on consumption location
• digital services follow destination-based taxation
Proper classification determines whether tax applies.
KEY COURT DECISIONS
Courts have confirmed:
• true exports of goods are zero-rated
• services consumed outside Canada may be zero-rated
• suppliers must document proof of export
• digital services often follow customer location, not supplier location
• mistaken tax charges must be refunded to customers
• zero-rating cannot be applied without proper evidence
Courts emphasize that the burden of proof is on the supplier.
WHY BUSINESSES GET CONFUSED ABOUT INTERNATIONAL SALES TAX
Common reasons include:
• assuming U.S. customers are automatically tax-free
• misunderstanding digital service rules
• not knowing what constitutes an “exported service”
• confusion between zero-rated and exempt
• treating Quebec customers outside the province as foreign buyers
• relying on incorrect e-commerce platform defaults
DO YOU NEED TO CHARGE GST/QST TO U.S. OR INTERNATIONAL CUSTOMERS?
Here is the clear breakdown.
1. SALES OF PHYSICAL GOODS TO U.S. OR INTERNATIONAL CUSTOMERS
Usually ZERO-RATED
If the goods are shipped from Quebec and delivered outside Canada:
• GST = 0%
• QST = 0%
You must keep documentation showing:
• shipping confirmation
• customs documents
• proof of export
If the customer picks up the goods in Quebec, GST/QST must be charged.
2. SERVICES PROVIDED TO U.S. OR INTERNATIONAL CLIENTS
Most services supplied to non-residents are zero-rated, except when the service is:
• related to real property in Canada
• related to goods located in Canada
• consumed in Canada
• a service to an individual physically in Canada during performance
Examples of zero-rated services to foreign clients:
• consulting
• software development
• design and creative services
• remote training
• digital marketing
• business advisory
• SaaS (if not used in Canada)
Examples of taxable services to foreign clients:
• services related to Canadian real estate
• repairs to goods located in Quebec
• certain in-person services performed in Quebec
• services consumed in Canada
3. DIGITAL PRODUCTS & SAAS TO U.S. OR INTERNATIONAL CLIENTS
If the customer is located outside Canada, digital supplies are generally zero-rated.
If the customer is in Quebec → QST applies.
If the customer is in another Canadian province → GST/HST/PST rules apply.
Destination-based rules apply.
4. TRAINING, COACHING, OR COURSES SOLD INTERNATIONALLY
If delivered to a customer located outside Canada:
• typically zero-rated
• but if the customer participates while physically in Quebec → GST/QST apply
Online courses delivered outside Canada are usually zero-rated.
5. SALES OF SERVICES TO NON-RESIDENT INDIVIDUALS IN QUEBEC
If the customer is physically in Quebec at the time of the service:
• GST/QST apply
Even if the customer lives in the U.S. or abroad.
6. SALES TO FOREIGN GOVERNMENTS OR ORGANIZATIONS
Most qualify for zero-rating, but documentation is required.
7. SPECIAL CASE: EXPORTING THROUGH FULFILLMENT CENTERS
If you use Amazon FBA or similar services:
• exports from Canada to foreign customers → zero-rated
• shipments from U.S. warehouses → may follow U.S. tax rules (no GST/QST)
Always track shipping origin and destination.
COMMON MISTAKES ON INTERNATIONAL SALES TAX
Businesses often:
• charge GST/QST when shipping internationally (incorrect)
• forget to zero-rate services provided to U.S. clients
• fail to document export shipments
• charge tax based on billing address only
• misconfigure Shopify or Amazon tax settings
• treat zero-rated sales as exempt (incorrect reporting)
• charge QST to international clients via payment processors
These errors lead to customer disputes and tax adjustments.
BEST PRACTICES FOR INTERNATIONAL SALES COMPLIANCE
• verify customer location before invoicing
• classify supplies as taxable, exempt, or zero-rated
• configure e-commerce platforms properly
• maintain proof of export for goods
• store contracts showing foreign service delivery
• reconcile zero-rated revenues separately
• ensure GST/QST amounts are not accidentally applied.
