How to use
- Enter the price and your tax rate.
- Use Add mode for a net price, or Extract mode for a price that already includes tax.
- Read the tax amount and the total, then adjust the rate to test other cases.
Note: Sales tax rates differ by goods, services and province. Rates change — verify with the official source before relying on this.
Tips

- Keep one consistent rate per invoice to avoid rounding confusion.
- The tool is a calculator — your invoice still needs the proper tax lines.
Frequently Asked Questions (FAQ)
What does the sales tax calculator do?
It adds sales tax to a net price, or backs the tax out of a tax-inclusive price, at any rate you enter.
What is the difference between Add and Extract mode?
Add mode puts tax on top of a net price. Extract mode works out the tax hidden inside a price that already includes it.
Can I change the sales tax rate?
Yes. The tax rate field is editable, so you can use any rate you need instead of a fixed one.
What figures does the result show?
The net price without tax, the sales tax amount, and the gross price with tax, so you can see all three figures at a glance.
