Popular Reverse Sales Tax Tools in Canada

Several online calculators offer reverse sales tax computation, including government resources, third-party financial sites, and software integrations. Here are some of the popular options:

  • Canada Revenue Agency (CRA) Calculator: Official but basic, the CRA calculator provides tax-inclusive and exclusive price calculations. However, it lacks provincial split details and advanced features.
  • SimpleTax Reverse Calculator: User-friendly, but doesn’t update automatically with the latest tax rates.
  • Financial Website Tools: Many financial portals provide quick calculators, but most focus on GST/HST only and do not separate PST or QST for certain provinces.
  • Accounting Software Plugins: Tools embedded within accounting platforms (like QuickBooks or Xero) handle tax calculations but can be costly and often require subscriptions.
