🟦 Frequently Asked Questions​

 

💰 Is GST calculated before or after the discount?

GST, HST, PST, RST, and QST are generally calculated after eligible discounts are applied. Promotional pricing and coupons may affect the taxable amount depending on the transaction.

​

🧾 Do I charge GST or HST on my business invoice?

If your business is registered for GST/HST, you generally need to charge the applicable GST, HST, PST, RST, or QST based on your customer's location and the place-of-supply rules. Always verify the correct tax treatment for your products or services.

​

📦 Which province's sales tax should I charge?

The applicable Canadian sales tax usually depends on where the goods are delivered or where the service is considered supplied. Different provinces have different GST, HST, PST, RST, and QST requirements.

​

💼 Who needs to register for GST/HST in Canada?

Most businesses must register for GST/HST once they exceed the small supplier threshold. Voluntary registration may also be beneficial because it can allow eligible businesses to claim Input Tax Credits (ITCs).
