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

Adding the taxes: $200.00
Amount before tax$200.00
GST (5%)$10.00
Total$210.00
Removing the taxes: $100.00
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 connects them to Claude, ChatGPT or Copilot, and its Sales tax return prompt has the assistant go over the period before you file: each sale or purchase with no tax code or a code that does not fit, the expenses whose tax is claimed back with no receipt, then the figures to enter on the return. With Autopilot, the Sales tax totals report emails you the tax collected, paid and net for each tax agency every month, quarter or year. Neither changes anything in your books.
