How the Northwest Territories Sales Tax Calculator Works

This calculator estimates the sales tax breakdown for purchases in Northwest Territories. Enter a before-tax amount (default) or switch to tax-included to reverse-calculate the subtotal.

  • Standard calculation: Enter the before-tax amount. Whether you are buying goods in Yellowknife or Inuvik, the calculator simply applies the flat 5% GST to show your final checkout price.
  • Reverse calculation (tax included): Turn on “Amount includes tax?”. Enter the final total you paid, and the calculator works backward to cleanly separate the 5% GST from the pre-tax base amount.

Understanding GST in the Northwest Territories

Consumers in Yellowknife and across the territory pay only the 5% federal GST. There is no PST or HST added to retail goods. While you may notice a 2% territorial payroll tax on your pay stub, this does not apply at the cash register.

Retail sticker prices in the NWT do not include the 5% GST, so you must always account for this addition at checkout. If you want to know exactly how much federal tax was included in your final purchase, simply use the 'Amount includes tax?' toggle.

How to calculate sales tax in Northwest Territories (before tax and tax included)

The formula used for the Northwest Territories is straightforward: Total = Amount × 1.05. To reverse the calculation and find the pre-tax sticker price from a receipt, just divide the total by 1.05.

Total including tax = Before-tax amount × (1 + 5%)
Before-tax amount = Total including tax ÷ (1 + 5%)
