Reverse Yukon GST Calculator

Yukon is the simplest jurisdiction in Canada for reverse calculation, and it has always been: the territory has never levied a territorial sales tax. Alberta repealed one in 1937; Yukon never introduced one at all. Every taxable receipt from Whitehorse to Dawson City carries the 5% federal GST and nothing else, dividing by 1.05. A $126.00 total is $120.00 of goods and $6.00 of GST, and the entire extracted amount is federal — fully claimable as an input tax credit by a registered business, with no provincial slice to strip out first.

Yukon's private sector is built on mining — gold, silver, zinc, and lead — and those operations generate the territory's largest reverse calculations. A $750,000 tax-included drilling or camp-services invoice separates into $714285.71 of cost and $35714.29 of recoverable GST. Because there is no territorial tax, that entire figure goes on the GST/HST return; the CRA's simplified ITC method states the same arithmetic as the 5/105 tax fraction applied to tax-included purchases.

The other common job is a visitor one. Yukon's Klondike-heritage tourism draws travellers who arrive from British Columbia or Alaska and compare receipts. Coming from BC, the change is real: a $112.00 Vancouver purchase contains $12.00 of tax across two taxes, only part of it recoverable, while a $112.00 Whitehorse purchase contains $5.33 of GST, all of it recoverable. Travellers reconciling a multi-jurisdiction trip should sort receipts by where the supply happened before applying any divisor — 1.05 is right for the Yukon ones only.

As everywhere in Canada, basic groceries, prescription drugs, and medical devices are zero-rated and carry no tax to extract, while residential rent, health care, and educational services are exempt.

Yukon's visitors arrive from Alaska, British Columbia, and overseas, and many assume Canada runs a tourist refund scheme like the VAT refunds common in Europe. It does not. Canada eliminated the Visitor Rebate Program in 2007. An individual traveller who buys a jacket in Whitehorse pays the 5% GST and keeps paying it — reversing the receipt tells them what the tax was, not what they can reclaim.

What replaced it is narrower: the Foreign Convention and Tour Incentive Program (FCTIP), which provides relief in defined circumstances — eligible tour packages that include accommodation, and foreign conventions and their organizers. Those are business-shaped claims with their own documentation rules, not something a visitor completes at the airport. For a Yukon tour operator packaging accommodation for non-resident travellers, the reverse calculation on the accommodation component is exactly the figure the claim turns on.

The everyday consequence for retailers is simpler: quote tax-inclusive prices to visitors if you like, but keep the 5% identifiable on the receipt. A tax-inclusive total of $126.00 needs to resolve to $120.00 plus $6.00 on paper, both for the customer's records and for your own return.

To back out the 5% sales tax from any Yukon receipt or invoice, use the standard algebraic reverse formula:

For a total of $100.00 CAD:

• Total Paid: $100.00 CAD
• Pre-Tax Base: $100.00 ÷ 1.0500 = $95.24 CAD
• Total Tax Owed: $100.00 - $95.24 = $4.76 CAD

Breakdown: GST Portion (100% of tax): $4.76 CAD | PST Portion (0% of tax): $0.00 CAD
