April 12, 2026 in Ontario, Canada — The 13% Harmonized Sales Tax on cars in Ontario is applied to every vehicle purchase from a dealership, making it one of the most significant costs Ontario car buyers face. Understanding exactly how HST on cars Ontario works — including what is taxable, what exemptions exist, and how the tax is calculated — helps you budget accurately and avoid surprises at the dealership.
What Is HST and How Does It Apply to Cars in Ontario?
HST, or Harmonized Sales Tax, is Canadas combined federal-provincial sales tax system used in Ontario and four Atlantic provinces. In Ontario, the HST rate is 13%, which consists of the 5% federal Goods and Services Tax (GST) combined with the 8% Ontario Provincial Sales Tax (PST). While you see it as a single 13% figure on your purchase documents, the Canada Revenue Agency internally splits this between the federal and provincial portions.
On a vehicle purchase, HST is calculated on the full pre-tax purchase price. This includes the base vehicle cost, any dealer-installed options and accessories, freight and transportation charges, and dealer administration fees. If you negotiate a $40,000 vehicle price and add $2,000 in accessories, your HST base is $42,000, resulting in $5,460 in total HST.

Is HST Charged on Used Cars in Ontario?
Yes, HST applies to used car purchases from Ontario dealerships just as it applies to new vehicles. The HST rate of 13% is the same regardless of whether the vehicle is new or used. A $25,000 used car from a dealership will attract $3,250 in HST, bringing the total to $28,250. When purchasing a used vehicle from a private seller in Ontario, HST is generally not charged because private sellers are typically not registered for GST/HST. However, you will still pay the $120 annual Ontario registration fee when transferring ownership.
HST on Cars Ontario: What Is Included in the Tax Base
The HST base on a vehicle purchase includes more than just the sticker price. Dealer-added accessories such as floor mats, roof racks, and rust-proofing are all subject to HST. Freight and destination charges from the manufacturer to the dealership are included in the HST calculation. Documentation fees, admin fees, and even extended warranty purchases through the dealership are subject to HST. Being aware of these additions helps you understand why your final HST amount may be higher than 13% of the advertised vehicle price.
Ontario HST on Cars: Exemptions and Special Cases
While HST applies to most vehicle purchases in Ontario, several exemptions exist. First Nations individuals purchasing vehicles on-reserve may qualify for HST exemptions under Section 87 of the Indian Act. The exemption applies to vehicles intended for use on-reserve, though the specific rules and documentation requirements are detailed. Commercial vehicles purchased for business use may qualify for input tax credits that allow businesses to recover the HST paid. Vehicles purchased as part of a residential property transaction may qualify for a new housing rebate, which can be applicable in some circumstances.
Federal Luxury Tax and HST on High-Value Vehicles
In addition to the 13% HST, vehicles priced above $100,000 are subject to a federal luxury tax of 10% on the amount exceeding $100,000. This is calculated separately from the HST. For a $150,000 vehicle, the HST would be $19,500 ($150,000 x 13%), plus a luxury tax of $5,000 (($150,000 - $100,000) x 10%), bringing the total tax to $24,500. Notably, SUVs and minivans with a gross vehicle weight rating above 3,856 kg are excluded from the luxury tax, which can make high-end SUV purchases significantly cheaper from a tax perspective than equivalent luxury sedans.
Ontario Does Not Offer Provincial EV Tax Rebates
Unlike British Columbia and Quebec, Ontario currently does not offer a provincial sales tax rebate or exemption for electric vehicle purchases. Ontario discontinued its provincial EV rebate program in 2018. However, the federal iZEV program still provides up to $5,000 for qualifying new zero-emission vehicles, which applies at the point of sale through participating dealerships. While Ontario lacks additional provincial EV incentives, EVs offer savings through reduced fuel costs, lower maintenance requirements, and exemption from Ontario Drive Clean emissions testing.
Private Sales: Avoiding HST on Cars in Ontario
One strategy to avoid HST on cars in Ontario is purchasing through a private sale. Most private vehicle sellers are not registered for GST/HST and are therefore not required to collect or remit sales tax. This means the purchase price is typically the total amount paid. However, there are important considerations: private sales offer fewer consumer protections, no dealer financing options, and no dealer warranty. You also assume all risk regarding the vehicle condition. When buying privately, ensure you receive proper documentation and complete the ownership transfer through ServiceOntario promptly to avoid liability issues.
Claiming HST Input Tax Credits for Business Vehicles
Business owners in Ontario who use vehicles for commercial purposes may be able to claim input tax credits (ITCs) to recover the HST paid on vehicle purchases. The ITC entitlement depends on the percentage of business use of the vehicle. For vehicles used 100% for business, the full HST paid is recoverable. For vehicles used partly for personal purposes, only the business-use percentage of the HST can be claimed as an ITC. This makes commercial vehicle purchases significantly more tax-efficient for businesses. Consult a tax professional to understand your specific ITC entitlements and reporting requirements.
Negotiating the Best Price Before HST
Understanding HST on cars Ontario means knowing that all negotiation should happen on the pre-tax price. Dealerships are required to add HST to whatever price you agree upon. By negotiating the total out-the-door price including HST, you may inadvertently pay more than necessary because dealers can adjust the pre-tax component to achieve their target after-tax price. Always negotiate the base vehicle price, accessories, and fees separately, and ask for a clear breakdown showing the pre-tax price before HST is calculated.
