Frequently asked
What's the difference between GST, PST, HST, and QST?
GST is the federal 5% Goods and Services Tax charged everywhere. Some provinces add their own PST or QST on top, others have merged GST with a provincial tax into a single HST rate. The presets here use each province's combined rate.
Do these rates change?
Occasionally, provinces do adjust their rates. The presets reflect commonly published combined rates, but confirm the current rate for your province before filing or invoicing.
Can I use this for a business filing GST/HST returns?
It's useful for quick price checks and quotes, but for an actual return, always use the CRA's official rates and guidance for your filing period.
Is this financial or tax advice?
No. This is a general estimate for planning purposes only, not financial, investment, or tax advice. Rates and figures can change. Confirm current numbers with a qualified professional before making decisions.
