Canadian tax requirements on discounts

Early Payment Discounts & GST/HST


For early-payment discounts on credit sales, you charge GST/HST on the full amount of the invoice, even if the customer takes the discount. (The same applies to late payment surcharges; if you are adding a surcharge for a late payment to a bill, GST/HST is charged only on the original invoiced amount.)

So suppose I invoiced a customer $500 for my landscaping services with credit terms offering the customer a 2% discount if she paid the bill within ten days of the invoice, and she paid the bill within that time, the amounts on the invoice would read (in a province such as Alberta where only GST applies to the sale):

Landscaping services = $500

GST @5% = $25

TOTAL $525

Minus 2% discount of $10 = $515

(See How to Invoice in Canada for information on what information has to be on your invoice, tax rates, and examples of complete invoices for GST, HST and/or PST.)

Volume Discounts & GST/HST

For volume discounts, how you apply GST/HST to the sale depends on whether you offer the discount at the time you make the sale or after you make the sale.

For a discount offered at the time of sale, you charge GST/HST on the net amount (the sale price minus the discount). So for instance, if a customer bought ten dancing hula lamps that normally cost $100 each and I was offering a 10 percent discount on that item, I would charge the customer GST/HST on the net amount of $900 ($1000 minus the $100 discount).

Volume discounts offered after the sale, such as discounts that customers earn over time, are a bit more complicated because you need to choose whether or not to credit the GST/HST related to the amount of the discount.

If you refund or credit the GST/HST for the volume discount to the customer and he is a GST registrant, (also charges and collects GST/HST), then you have to issue the customer a credit note explaining the adjustment, telling him what the discount is and the related amount of GST/HST.

This can also be worked the other way around, with the customer issuing you a debt note to explain the adjustment. As long as the amount credited or debited was previously included in your net tax, you can deduct the amount of GST/HST adjusted when you are determining your net tax for the period in which you issued the credit note or received the debit note.
