How this Canada GST calculator works
This Canada GST calculator is designed to be practical for everyday use. It handles federal GST, harmonized sales tax (HST), and combined GST + provincial sales taxes (PST, RST, or QST) depending on the province or territory you select.
You can use it in two ways:
- Add tax: Start with a pre-tax price and compute the total including tax.
- Remove tax: Start with a tax-included amount and extract the pre-tax subtotal and tax amount.
This is useful for invoices, receipts, budgeting, e-commerce pricing, freelance work, and small business bookkeeping.

Add tax vs remove tax
1) Adding GST/HST/PST to a pre-tax amount
If your listed price is before tax, calculate:
Tax amount = Pre-tax amount × (Rate ÷ 100)
Total = Pre-tax amount + Tax amount
2) Removing GST/HST/PST from a tax-included amount
If your listed amount already includes tax, calculate:
Pre-tax amount = Tax-included total ÷ (1 + Rate ÷ 100)
Tax amount = Tax-included total - Pre-tax amount
This “remove tax” function is especially useful when reconciling receipts or calculating the net sale amount for accounting entries.
Practical examples
Example A: Ontario invoice (add tax)
If your pre-tax amount is $250 in Ontario (13% HST):
- Tax = $250 × 0.13 = $32.50
- Total = $250 + $32.50 = $282.50
Example B: Alberta receipt (remove tax)
If you paid $105 in Alberta (5% GST included):
- Pre-tax = $105 ÷ 1.05 = $100.00
- GST = $5.00
Example C: Quebec sale (add tax)
For a $1,000 pre-tax amount in Quebec (14.975% total):
- Tax = $149.75
- Total = $1,149.75
Tips for freelancers and small businesses
- Separate tax from revenue: Tax collected is generally not your income.
- Store tax breakdowns: Keep clear records of GST and provincial portions when needed.
- Use consistent rounding: Most businesses round to two decimals per invoice line or invoice total based on policy.
- Know exemptions: Not all products and services are taxed the same way.
- Review province-specific rules: Registration, filing, and remittance obligations can vary.
Frequently asked questions
Is GST the same in every province?
The federal GST portion is 5%, but the total sales tax differs because provinces either add a provincial component or use HST.
What is the difference between GST, HST, and PST?
GST is federal tax, HST is a combined federal-provincial system in certain provinces, and PST/QST/RST are provincial taxes collected under different provincial frameworks.
Can I use this tool as a reverse tax calculator?
Yes. Choose Remove tax from tax-included amount to extract the pre-tax price and tax portion.
Does this replace professional tax advice?
No. This calculator helps with quick estimates and day-to-day calculations. For compliance, filing, and edge cases, consult CRA guidance or a qualified tax professional.
