Canada GST Calculator
Canada has two layers of consumption tax: a federal GST of 5% everywhere, plus provincial taxes. Ontario (13%), New Brunswick, Newfoundland & Labrador and Nova Scotia (15%) use combined HST. Quebec adds QST (9.975%), while BC (7% PST), Saskatchewan (6%) and Manitoba (7% RST) run separate provincial sales taxes. Alberta has no provincial tax — just 5% GST.

Canada GST/HST FAQ
What is the difference between GST, QST and HST?
GST is the 5% federal tax. HST merges the federal and provincial portions into one rate collected by the CRA (13–15% depending on province). Quebec runs GST plus its own QST at 9.975% separately, so the combined burden is 14.975% — enter that as a custom rate.
Which rate should I use for Ontario?
Ontario's harmonized rate is 13% HST. Select the HST 13% chip — the calculator treats it as a single combined rate for adding or removing tax.
How do I remove GST from a receipt total?
Use "Remove tax" mode, enter the total, and pick the applicable rate. At plain 5% GST, GST = Total × 5/105. At 13% HST, the tax portion = Total × 13/113.
Do basic groceries attract GST in Canada?
No — basic groceries are zero-rated, as are certain medical devices and prescription drugs. Fully-processed foods, restaurant meals and snacks are taxable.
How much is GST on $100 in Canada?
At the federal 5% rate: GST = $5.00, total $105.00. In Ontario at 13% HST: $13.00 → $113.00. In Nova Scotia at 15%: $15.00 → $115.00. Pick your province’s rate chip or type a custom combined rate.
What is the GST/HST on $1,000?
5% GST-only provinces (Alberta, territories): $50.00 → $1,050. Ontario (13% HST): $130.00 → $1,130. Nova Scotia/New Brunswick/PEI (15%): $150.00 → $1,150. Quebec (5% GST + 9.975% QST): $149.75 → $1,149.75.
Which provinces use HST in Canada?
Ontario at 13%; Newfoundland & Labrador at 14%; Nova Scotia, New Brunswick and Prince Edward Island at 15%. Others run separate provincial taxes: Quebec (QST 9.975%), BC (PST 7%), Saskatchewan (6%) and Manitoba (RST 7%) — all stacked on the 5% GST.
How do I remove 13% HST from a total?
Base = Total × 100 ÷ 113 and HST = Total × 13 ÷ 113. From a $1,130 HST-inclusive receipt: base $1,000.00 and HST $130.00. Select the HST 13% chip in "Remove tax" mode and enter the total.
Who actually pays GST in Canada?
The final consumer. GST-registered sellers collect it on sales and claim credits on purchases, so the net burden flows down the chain to end customers — including through used-goods and service purchases, subject to exemptions like basic groceries and rents of used residential housing.
Do tourists get a GST/HST refund in Canada?
Generally no — the former Visitor Rebate Program ended in 2007. Limited rebates survive only for non-resident conventions and certain new housing (New Residential Rental Property rebate). Tourists simply pay the posted tax at checkout.
How often do Canadian businesses remit GST/HST?
Reporting periods depend on taxable sales: annual (≤$500,000), quarterly ($500,001–$6,000,000) or monthly (>$6,000,000), chosen with the CRA at setup. Returns are due one month after the period ends (self-assessed filers get extra time).
About this Canada GST/HST calculator
Canada's consumption tax has two layers: the federal GST of 5%, and provincial sales taxes that either merge into a harmonized HST (13% in Ontario, 14% in Newfoundland & Labrador, 15% in Nova Scotia, New Brunswick and PEI, all collected by the CRA) or run separately (Quebec's QST of 9.975% on top of GST, BC's PST, Saskatchewan and Manitoba's RST). This Canada GST calculator ships chips for the common HST rates and accepts custom combined rates — for example 14.975% for Quebec, or 12% for BC plus PST.
Use it to add tax when pricing, or to remove it from an inclusive receipt to recover the taxable amount and the tax paid.
