|---|---|---|---|
| GST (goods and services tax) | 5% | January 1, 2008 | Canada Revenue Agency |
The calculation
On $200 before tax the GST is $10 and the total $210. A business in the territory that ships to an HST province charges that province's HST, not 5%.
Registering
The threshold is the GST one used across Canada: $30,000 of taxable supplies over four consecutive calendar quarters, or within a single quarter.
One example, both ways
| Amount before tax | $200.00 |
|---|---|
| GST (5%) | $10.00 |
| Total | $210.00 |
| Amount before tax | $95.24 |
|---|---|
| GST (5%) | $4.76 |
| Total | $100.00 |
To remove the taxes, divide the total by 1.05, then check that the price you get plus its rounded taxes adds back up to the total.

Before the return, in QuickBooks
This calculator settles one invoice at a time. If your books are in QuickBooks Online, Caribooks has an Autopilot loop, Sales tax check, that goes over last month before the return. It flags each sale or purchase with no tax code, with a code unusual for that customer or vendor, or with tax that does not match its code's rate, then totals the tax collected, paid and net for each tax agency. It only reads: nothing in your books changes.
