Sticker shock doesn’t stop at the price tag. Whether you buy from a dealership or a private seller, the province you live in decides how much sales tax gets added to your car — and the rules aren’t the same for both. Some provinces charge less tax on a private sale. Others charge the same rate no matter who you buy from. This guide breaks down exactly what you’ll owe in every province, so you can budget accurately before you apply for financing.
TL;DR: Dealer purchases are taxed at your province’s combined GST/HST or GST+PST rate. Private sales skip GST but still usually get hit with a provincial tax at registration — calculated on the higher of the sale price or the vehicle’s average wholesale value. Alberta is the only province with no provincial sales tax on either type of purchase

Canada applies two layers of consumption tax to vehicle purchases: the federal Goods and Services Tax (GST) at 5%, and a provincial tax that varies by where you live. Depending on the province, that provincial tax shows up as HST (Harmonized Sales Tax), PST (Provincial Sales Tax), RST (Retail Sales Tax), or QST (Quebec Sales Tax).
Dealerships are GST/HST registrants, so they must collect the full combined tax on every sale. Private sellers are not registrants — they’re just individuals selling a vehicle they own — so GST typically doesn’t apply to a private sale. That’s the main reason private sales often look cheaper on paper.
But most provinces close that gap with a separate provincial tax collected when you register the vehicle, not at the point of sale. According to the Financial Consumer Agency of Canada (FCAC), this registration-based tax is calculated on whichever is higher: the price you actually paid, or the vehicle’s average wholesale value from a recognized guide like Canadian Black Book. That rule exists specifically to prevent buyers and sellers from under-reporting the sale price to dodge tax.
When you buy from a licensed dealer, tax is calculated on the negotiated purchase price and charged at the point of sale, the same way it would be on any retail purchase. In HST provinces, that’s one combined rate. In GST+PST provinces, you’ll see both taxes itemized separately on your bill of sale. Understanding how car loans work in Canada is worth doing before you negotiate, since the sales tax gets rolled into your total financed amount in most cases — it isn’t something you typically pay out of pocket on top of your loan.
NEW, USED & CERTIFIED
Private sales skip the federal GST because the seller isn’t a business collecting tax on Canada Revenue Agency’s behalf. That’s the appeal of buying private — the sticker price often looks lower. But almost every province still collects a provincial tax when you go to register the vehicle, and it’s calculated the same way regardless of what you and the seller agreed to pay.
A few things to know before you buy private:
| Province | Dealer Sale Tax | Private Sale Tax |
|---|---|---|
| Ontario | 13% HST | 13% RST (on greater of price or wholesale value; no GST) |
| British Columbia | 12% (5% GST + 7% PST) | 12% PST (no GST) |
| Alberta | 5% GST only | 5% GST only (private sales exempt) |
| Quebec | 14.975% (5% GST + 9.975% QST) | 9.975% QST (no GST) |
| Manitoba | 12% (5% GST + 7% RST) | 7% RST (no GST) |
| Saskatchewan | 11% (5% GST + 6% PST) | 6% PST (no GST) |
| Nova Scotia | 15% HST | 15% provincial vehicle tax (no GST) |
| New Brunswick | 15% HST | 15% provincial vehicle tax (no GST) |
| Prince Edward Island | 15% HST | 15% provincial vehicle tax (no GST) |
| Newfoundland and Labrador | 15% HST | 15% provincial vehicle tax (no GST) |
Two patterns stand out. Alberta is the only province with no provincial sales tax at all, on dealer or private purchases — you’ll only ever pay the 5% GST there. Everywhere else, buying private saves you the GST portion, but the provincial rate usually lands close to what you’d pay at a dealership once the wholesale-value rule is applied. Tax rates and thresholds change periodically, so confirm the current rate with your provincial vehicle registry before you finalize a private purchase.
In Ontario, Canada’s largest auto market, private sales are still assessed 13% RST at the ServiceOntario counter based on the Canadian Red Book wholesale value, regardless of what’s on your bill of sale — dealers licensed through OMVIC handle the tax differently since it’s baked into the HST at time of sale. In British Columbia, private used-vehicle sales are taxed at 12% PST, matching the dealer rate, following a provincial change designed to close the tax gap between the two channels. In Alberta, the absence of any provincial sales tax is one of the province’s biggest draws for both dealer and private buyers, especially on higher-value trucks and SUVs.
Sales tax isn’t usually a separate bill — for most buyers, it gets rolled into the total amount financed. That means the tax you pay directly increases your monthly payment and the total interest you’ll pay over the life of the loan. A car priced at $20,000 in Ontario, for example, becomes a $22,600 loan once 13% HST is added, before any other fees. Autofix Credit factors this in when working out a payment plan that fits your budget, whether you’re buying from a dealer or bringing in a private sale for financing. Browsing available vehicle inventory with the total taxed price in mind — not just the listed price — will give you a much more realistic sense of what your payments will look like.
Whatever the tax works out to, Autofix Credit can help you find a financing option that accounts for the full cost — not just the sticker price.

Do I pay sales tax on a private car sale in Canada?
Yes, in every province except Alberta. Most provinces charge a provincial tax (PST, RST, or QST) on private vehicle sales, calculated on the higher of the sale price or the vehicle’s average wholesale value. You typically pay this tax when you register the vehicle, not at the time of purchase.
Which province has no sales tax on cars?
Alberta is the only Canadian province with no provincial sales tax on vehicles, for dealer or private sales. You’ll still pay the 5% federal GST on any purchase there.
Is sales tax lower on a private car sale than a dealer sale?
Usually yes, because private sales skip the 5% GST that dealers must charge. However, the provincial portion of the tax is often calculated the same way for both, so the total gap can be smaller than expected once wholesale value is factored in.
Can I avoid paying tax when buying a car from a family member?
In several provinces, transfers between immediate family members — such as a parent and child or spouses — are exempt from provincial vehicle tax. Requirements vary by province, so check with your provincial vehicle registry for the exact eligibility rules and paperwork needed.
Does sales tax get added to my car loan?
Yes, in most financing arrangements, sales tax is included in the total amount you finance rather than paid separately upfront. This means it affects both your monthly payment and the total interest paid over the loan term.
