GST Calculator for Canada
Base price entered. 13% tax will be added on top.
Calculating Goods and Services Tax (GST) and Harmonized Sales Tax (HST) in Canada shouldn't involve guesswork or manual spreadsheets. Whether you are generating a commercial B2B tax invoice, reconciling operating expenses for CRA filing, or verifying retail prices with inclusive tax, our interactive calculation engine delivers statutory precision in milliseconds.
The Canadian consumption tax system, administered by the Canada Revenue Agency (CRA) and provincial revenue authorities, operates on a federalist architecture. Every commercial transaction requires computing the base taxable value, identifying the correct provincial tax bracket (5% to 15%), and bifurcating tax revenues between the Federal Government (5% GST) and provincial finance rails (PST, QST, or provincial HST components).
How to Use Our Canada GST Calculator
Step-by-step instructions to calculate inclusive and exclusive sales tax across all 13 Canadian provinces and territories.
Step 1: Enter the Transaction Amount
Type your invoice amount or quote in Canadian Dollars ($ CAD), or drag the interactive slider between $0 and $10,000,000 for instant testing. Quick preset buttons let you jump directly to common denominations like $100, $500, $1,000, or $5,000.
Step 2: Select Your Province or Territory
Choose your jurisdiction from the dropdown menu (such as Ontario 13% HST, British Columbia 12% GST+PST, Quebec 14.975% GST+QST, or Alberta 5% GST). The calculator automatically loads the statutory federal and provincial tax components, including Nova Scotia's updated 14% rate.
Step 3: Choose Between Adding Tax or Removing Tax
Select Add Tax (Exclusive) when preparing a commercial quote and adding tax to bill a client. Select Remove Tax (Inclusive) when reconciling a receipt or gross expense and extracting the pre-tax base cost and embedded tax.
Step 4: Review the Federal and Provincial Split
The output card instantly updates your Total Gross Amount, Base Taxable Value, Total Sales Tax Liability, and the exact statutory split between Federal GST (5%) and the applicable provincial tax rail (PST, QST, or provincial HST component).
