What is the HST rate in Ontario?

13% 5% federal GST combined with an 8% provincial portion, collected as a single harmonized tax by the Canada Revenue Agency.

What is Nova Scotia's HST rate in 2026?

14%. It decreased from 15% on 1 April 2025, when the provincial portion fell from 10% to 9%. The 5% federal GST was unchanged. Transitional rules apply to transactions straddling that date.

How do I calculate HST backwards?

Divide the tax included total by 1 plus the rate. For $1,130 in Ontario: $1,130 ÷ 1.13 = $1,000 pre tax, with $130 HST. Don't subtract 13% from the total that gives $983.10, which is wrong, because the tax was calculated on the smaller figure.

Which provinces have HST?

Five: Ontario at 13%, Nova Scotia at 14%, and New Brunswick, Newfoundland and Labrador and Prince Edward Island at 15%. British Columbia, Saskatchewan and Manitoba charge GST plus a separate provincial tax; Quebec charges GST plus QST; and Alberta, the Northwest Territories, Nunavut and Yukon charge 5% GST only.

Do I charge my province's rate or my customer's?

Your customer's. The rate follows the place of supply generally where goods are delivered or where the service recipient is located. A business in Alberta selling to an Ontario customer charges 13% HST, despite Alberta having no provincial sales tax.

When do I have to register for GST/HST?

Once worldwide taxable revenue exceeds $30,000, measured either over four consecutive calendar quarters or within a single quarter. You stop being a small supplier immediately before the sale that pushes you over, and must generally register within 29 days. Charities and non profits have a $50,000 threshold.

What's the difference between zero rated and exempt?

Both mean the customer pays no tax, but zero rated supplies stay inside the system so the business can claim input tax credits, while exempt supplies fall outside it and the business cannot. Basic groceries and prescription drugs are zero rated; residential rent and most health services are exempt.

Is there tax on books in Ontario?

Only the 5% federal GST. Ontario provides a point of sale rebate of the 8% provincial portion on books, children's clothing and footwear, car seats, diapers, newspapers, and qualifying prepared food and beverages costing $4.00 or less before tax.

Why is Quebec's rate 14.975% and not 15%?

Because QST at 9.975% is calculated on the pre GST price rather than on the GST inclusive amount. QST was compounded until 2013; since then the two taxes both apply to the base price, giving a combined 14.975%.

Can businesses claim back PST?

Generally no. PST in British Columbia and Saskatchewan, and RST in Manitoba, are not recoverable through input tax credits they're a hard cost. GST, HST and Quebec's QST are recoverable for registered businesses.

Does Alberta have sales tax?

Only the 5% federal GST. Alberta is the only province with no provincial sales tax, alongside the Northwest Territories, Nunavut and Yukon. But an Alberta business selling to customers in other provinces must charge those provinces' rates.

What is the Quick Method?

A simplified way to calculate GST/HST remittances. You charge the normal rate but remit a lower percentage of tax included sales, in place of claiming most input tax credits. There's a $400,000 threshold. It usually suits service businesses with low input costs and is often worse for input heavy businesses.

How to Calculate It

HST Provinces

One rate, one calculation. Price × rate. $1,000 in Ontario × 0.13 = $130 tax ($1,130 total).

GST + PST Provinces

Two taxes, both calculated on pre tax price. $1,000 in BC: GST $50 + PST $70 = $120 tax ($1,120 total).

Quebec (QST)

QST calculated on pre GST amount. $1,000: GST $50 + QST $99.75 = $149.75 tax ($1,149.75 total).

Working Backwards From a Total

If you have a receipt showing a tax included total and need the pre tax amount for an expense claim or bookkeeping, divide rather than subtract.

Pre tax = Total ÷ (1 + rate)

Tax = Total minus Pre tax

Example (Ontario $1,130 total): $1,130 ÷ 1.13 = $1,000 pre tax, tax $130.

Which Rate Do You Charge? (Place of Supply Rule)

You charge the rate of your customer's province, not your own.

A consultant in Toronto billing a client in Halifax charges 14% HST, not 13%. A freelancer in Calgary billing an Ontario client charges 13% HST despite Alberta having no provincial sales tax at all.
