How to calculate GST in Yukon
Adding GST: tax = price × 0.05, total = price × 1.05. Removing GST from a total: price = total ÷ 1.05, tax = total − price.
Worked example on $100
A $100 purchase: tax = $100 × 0.05 = $5.00. Total = $100 + $5.00 = $105.00. Working backwards from that $105.00 total: price = $105.00 ÷ 1.05 = $100.00, tax = $105.00 − $100.00 = $5.00.
What's taxed and what's GST-exempt
With no territorial sales tax, the only tax this calculator works out is the 5% GST, and the usual federal exemptions apply on top: basic groceries, prescription drugs, most health and dental services, and long-term residential rent are GST-exempt everywhere in Canada. A $4 loaf of bread is tax-free; a $4 chocolate bar carries the full 5%.
Why Yukon doesn't need a sales tax
Yukon charges only the 5% federal GST, the same as the Northwest Territories and Nunavut. All three territories lean heavily on Territorial Formula Financing, the federal transfer program built specifically for them: Yukon alone expected roughly $1.5 billion in federal transfer payments for the 2025-26 fiscal year. That scale of federal funding is a large part of why none of the three territories has introduced a provincial-style sales tax of their own.
No territorial payroll tax either
Unlike the Northwest Territories and Nunavut, which both charge a 2% payroll tax on anyone working in the territory, Yukon has no equivalent payroll tax. That makes the 5% GST the only tax this calculator needs to account for in Yukon.
Registering to collect GST as a small business
With no territorial sales tax and no territorial payroll tax, GST/HST registration with the CRA is the only sales-tax registration to think about in Yukon. You must register once your total taxable revenue (including any associated businesses) passes $30,000 over four consecutive calendar quarters, or within a single quarter; below that you're a small supplier and registration is optional.
