Why Reverse Sales Tax Calculation Matters
Receipts and invoices usually show only the tax-included total — not the pre-tax price. Reversing the calculation matters for bookkeeping (separating revenue from tax collected for GST/HST or PST remittance), expense reports, and price comparisons across provinces. Because dividing by (1 + rate) isn't the same as simply subtracting the rate, doing this by hand is a common source of errors — the calculator above handles it exactly.
History & How the Rate Is Built
Like Canada's other two territories, the Northwest Territories has never levied a territorial sales tax, relying instead on federal transfer payments and resource-sector revenue (diamonds, oil, and gas) to fund territorial government.
With no territorial sales tax, Northwest Territories residents and visitors pay only the 5% federal GST on purchases — the territorial government instead depends heavily on federal formula financing transfers, which make up the majority of territorial revenue.
Business Use Case: Registering in Northwest Territories
A business selling into the Northwest Territories only needs to register for and collect the federal 5% GST once its worldwide taxable revenue crosses $30,000 — there is no territorial sales tax registration step at all.
Real-World Example
A $100.00 purchase in Northwest Territories at the combined rate of 5.00%:
- Tax amount: $100.00 × 5.00% = $5.00
- Total price: $100.00 + $5.00 = $105.00
Northwest Territories Tax Registration for Businesses
Businesses must register for GST once their worldwide taxable revenue exceeds $30,000 in a calendar quarter or over four consecutive quarters.
