GST/HST Treatment of Coupons, Manufacturers' Rebates, and Gift Certificates

Have you sometimes wondered why, when you buy an item which is on sale, you have to pay GST or HST on the original price?  Many stores have in-store coupons that they apply, without the customer having to bring the coupon to the store themselves.  Often, when a coupon is applied to reduce the price, the tax is charged on the full price before the coupon.

There are different types of coupons, and two different treatments for these coupons.  Sometimes the GST or HST is charged on the selling price before the amount of the coupon is applied, and sometimes it is charged based on the net amount after the coupon is applied.

Reimbursable Coupons

These coupons are also called manufacturers coupons.  The vendor accepting the coupon from a customer is entitled to be reimbursed by the manufacturer or another third party.  When this type of coupon is used for a taxable purchase, the GST or HST is applied to the full price of the item, and then the value of the coupon is deducted.  For instance, for the purchase of a taxable item with a price of $10 in Ontario, with a $3 coupon being accepted from the customer, the HST would be calculated as follows:

Non-reimbursable Coupons

These coupons are issued by the vendor, so the vendor is not being reimbursed by some other entity for the value of the coupon.  The coupon may entitle the customer to a reduction of a fixed dollar amount or a percentage amount.  With this type of coupon, the vendor can either

If the coupon is not treated by the vendor as a reimbursable coupon, the following example shows how the HST would be calculated in Ontario, using an item priced at $10 and a $3 coupon:

Gift Certificates

When gift certificates are used to pay for part of a taxable purchase, the GST or HST is calculated based on the price of the 

item, and then the amount of the gift certificate is deducted, as if it were cash, as in the following example:

Manufacturers' Rebates

Manufacturers' rebates are usually provided to the customer after the customer has purchased the product at full price from a retailer, with the customer mailing in a form to get the rebate.  Sometimes the rebate is provided through the retailer when the goods are purchased.  In either case, the retailer collects the GST/HST on the full retail price before deducting the rebate amount.

If the customer making the purchase and receiving the rebate is a GST/HST registrant, and entitled to claim an input tax credit (ITC) for the GST or HST, special rules apply to manufacturers' rebates.  If the customer has been made aware in writing that the rebate includes GST/HST, then the customer will have to remit GST/HST equal to 5/105^ths for GST, or 12/112^ths, 13/113^ths, 14/114^ths or 15/115^ths of the rebate amount, depending on the GST/HST rate.

Other Coupons

Some other coupons are not for one specific monetary discount, such as:

With this type of coupon, the GST or HST is calculated based on the amount after deducting the value of the coupon.

Vendor Input Tax Credits re Coupons

When a vendor accepts a reimbursable coupon, or a non-reimbursable coupon which is being treated as a reimbursable coupon, an input tax credit (ITC) can be claimed for the tax portion of the coupon, which will be based on the current sales tax rates:

When the coupon amount has been deducted from the price of an item before calculating the GST or HST, then no ITC would be claimed for the coupon.
