Credit Note

Multiply the pre-tax price by the combined rate for the province where the supply is made, then add that amount to the price. If the price already includes tax, divide the total by one plus the rate to get the pre-tax amount, and the difference is the tax. The rate depends on the province of supply rather than where your business sits, so verify the current rate for that province and confirm the item is not zero-rated or exempt.

The HST is a single sales tax blending the federal 5% GST with a participating province's own sales tax, collected and administered by the CRA. For 2026 it is 13% in Ontario, 14% in Nova Scotia since 1 April 2025, and 15% in New Brunswick, Newfoundland and Labrador, and Prince Edward Island. A registrant charges HST on taxable supplies, claims input tax credits on its purchases, and remits the difference on one return. Elsewhere you charge the 5% GST plus any separate provincial tax.

Tax makes up a large share of the retail price, and the exact share depends on the province. Three layers stack: federal excise duty on the tobacco, a provincial tobacco tax, and then GST or HST charged on the selling price. Provinces change their tobacco tax with almost every budget, so take the figures from your province's tobacco tax page and the federal excise duty rate schedule rather than from a general article.

Tax free means no tax is payable on the amount at all, as with growth inside a TFSA, most gifts and inheritances, lottery winnings and certain non-taxable employee benefits. It differs from tax-deferred, where an RRSP only postpones tax until withdrawal. In sales tax it means something narrower again: zero-rated supplies are taxed at nil while exempt supplies sit outside GST/HST, which decides whether the seller can recover tax paid on costs.
