Formula & methodology

Formula used

Adding tax

tax = subtotal × rate
total = subtotal + tax

Removing tax (price is tax-inclusive)

subtotal = total ÷ (1 + rate)
tax = total − subtotal

Step-by-step calculation

1. Select province
Determines the combined rate: 5% GST-only, 5% GST + provincial PST/QST, or a single harmonized HST rate.
2. Add or remove tax
Add-tax multiplies the entered amount by the rate; remove-tax backs the pre-tax subtotal out of a tax-inclusive total.
3. GST/PST split
For non-HST provinces, the 5% GST portion and the provincial PST/QST portion are shown separately.

Limitations

Uses each province's standard combined rate — does not determine product-specific exemptions or zero-rating (e.g. basic groceries, most health/financial services).
Does not determine GST/HST registration eligibility; see the $30,000 small-supplier threshold in the FAQ.

Help & FAQs

Frequently Asked Questions

Clear answers to common questions to help you use this calculator confidently.

What is the GST rate in Canada in 2026?

Tap to view the answer

The federal GST is 5% in every province and territory. Some provinces combine it with a provincial portion into a single Harmonized Sales Tax (HST), ranging from 13% to 15%.

Which provinces use HST, and which charge GST + PST separately?

Tap to view the answer

Ontario charges 13% HST, Nova Scotia 14% HST, and New Brunswick, PEI, and Newfoundland & Labrador each charge 15% HST. BC, Saskatchewan, and Manitoba charge 5% GST plus a separate provincial PST. Quebec charges 5% GST plus 9.975% QST (administered by Revenu Québec, not CRA). Alberta, Yukon, NWT, and Nunavut charge only the 5% GST — no provincial sales tax.

When does a business need to register for and charge GST/HST?

Tap to view the answer

Once your total taxable revenue (including any associated businesses) exceeds $30,000 over four consecutive calendar quarters — or in a single quarter — you're no longer a 'small supplier' and must register, generally within 29 days, and start charging GST/HST.

Can a business recover GST/HST paid on expenses?

Tap to view the answer

Yes. Businesses registered for GST/HST can claim Input Tax Credits (ITCs) to recover the tax they paid on eligible business purchases and expenses, reported on their GST/HST return.

What GST/HST situations does this calculator not cover?

Tap to view the answer

It applies each province's standard combined rate but doesn't determine whether a specific product or service is exempt or zero-rated (e.g. basic groceries, most health and financial services). Confirm exemptions and your registration obligations with CRA guidance or an accountant.

Understanding GST, HST, PST and QST in Canada

One country, four different sales tax systems

Canada does not have a single sales tax. The federal GST is 5% everywhere, but what sits on top depends entirely on your province.

Five provinces use a Harmonized Sales Tax that merges the federal and provincial portions into one rate: Ontario at 13%, Nova Scotia at 14%, and New Brunswick, Prince Edward Island and Newfoundland and Labrador at 15%. British Columbia, Saskatchewan and Manitoba charge GST plus a separate provincial sales tax. Quebec charges GST plus QST, giving a combined 14.975%. Alberta and the three territories charge GST only, at 5% — the lowest consumption tax burden in the country.

Why PST provinces are not the same as HST provinces

The distinction matters more than the headline rate suggests. Under HST, businesses recover the full tax they pay on inputs through input tax credits, so the tax is only really borne by the final consumer.

Under a separate PST, businesses generally cannot recover the provincial portion on their inputs. That tax gets embedded in their costs and passed forward in prices, so it can be charged more than once along a supply chain. This is why economists generally prefer harmonised taxes, and why the two systems are not directly comparable even when the combined percentage is similar. British Columbia's PST also applies to a narrower set of goods than the HST does.

Extracting tax from a tax-included price

Working out the tax inside a total is not as simple as taking 13% of it — that overstates the tax, because the 13% was applied to the smaller pre-tax figure.

Divide the total by 1 plus the rate to get the base. A $113 total in Ontario divides by 1.13 to give $100 before tax and $13 of HST. Taking 13% of $113 would wrongly suggest $14.69. The same logic applies in reverse for Quebec's 14.975%: divide by 1.14975. This matters for anyone claiming input tax credits, reimbursing expenses, or reconciling a receipt that shows only a total — an error here compounds across every transaction in a year.

What is zero-rated, exempt, or simply not taxed

Basic groceries — bread, milk, vegetables, meat — are zero-rated, meaning taxed at 0%. Prescription drugs and most medical devices are too. Restaurant meals, snack foods and prepared items are fully taxable, which is why a rotisserie chicken and a bag of flour attract different treatment in the same shop.

Exempt supplies are a different category: most health and dental services, residential rent, and financial services. The practical difference is that a zero-rated supplier can still recover the GST on their own inputs, while an exempt supplier cannot. Provinces also carve out their own exceptions — Ontario charges only the 5% federal portion on children's clothing, books and prepared food under $4.

Registering a business, and the $30,000 threshold

A business must register for GST/HST once its worldwide taxable revenue exceeds $30,000 over four consecutive calendar quarters. Below that you are a small supplier and registration is optional.

Voluntary registration is often worth it anyway. Once registered you can claim input tax credits recovering the tax you paid on business purchases — equipment, software, supplies, professional fees. For a new business with significant startup costs and mostly business customers, that recovery can exceed the administrative burden. The calculation changes if you sell to consumers, since adding 13% to your prices makes you less competitive against unregistered rivals. The quick method of accounting can simplify filing for smaller businesses.

The GST/HST credit for lower-income households

The GST/HST credit is a quarterly tax-free payment that offsets sales tax for people with modest incomes. It is not the same thing as the sales tax itself and is easy to overlook because it arrives automatically.

Eligibility and amount are calculated from the net income on your tax return, which is why you must file even with no income at all — thousands of people miss the credit every year simply by not filing. It is paid in January, April, July and October, and the amount depends on income, marital status and number of children. Several provinces add their own credits, paid alongside it. A change in marital status or a new child should be reported promptly, since the amounts adjust.
