How Much Tax Do You Pay on a Used Car in Ontario?

Introduction: Understanding Ontario Used Car Taxes

When you are purchasing a car in Ontario, you’ll have to pay tax. The tax works the same whether you buy from a dealer or a private seller. You pay 13% sales tax on whichever is higher: the price you paid or the province’s wholesale value. A buyer then registers the vehicle and pays retail tax, if applicable, and the dealer just adds Harmonized Sales Tax (HST)  at the time of sale.

Some transactions and gifted vehicles may not have to pay tax. The guide provides details on how tax works, how to calculate it, who is responsible for paying tax, and how some exemptions work. This will help you avoid confusion and prevent unnecessary costs.

Ontario Car Tax When Buying from a Licensed Dealer

If you purchase a used vehicle from a licensed dealer in Ontario:

• • A 13% HST is applied to the total purchase price.
  • The dealer collects that tax at the time of purchase.
  • After that, you won’t need to pay any additional tax during registration.

This is a simple and convenient process since the dealer handles the paperwork and taxes at the same time.

Example:

Vehicle price: $15,000
HST = 13% of $15,000 = $1,950
Total price paid: $16,950

Ontario Car Tax for Private Used Car Sales

When you purchase a vehicle from a private individual:

The seller does not charge tax.

You must pay 13% Retail Sales Tax (RST) at ServiceOntario when registering the vehicle.

The tax owing will be based on the greater of:

1. 1. The amount paid (bill of sale); or
   2. The wholesale value as indicated in the Canadian Red Book832

Even if you buy the vehicle at a lower price, you’ll still be taxed on the Red Book value if it’s higher.

Example:

Purchase price: $8,000
Red Book value: $9,200
RST = 13% of $9,200 = $1,196
You pay $1,196 in tax at registration.

Canadian Red Book Value: How It Affects Ontario Car Tax

The Canadian Red Book provides wholesale values for used vehicles. ServiceOntario uses this value to establish the taxable amount during registration. If your purchase price is lower than the Red Book value, ServiceOntario will always use the higher Red Book value for tax. You cannot lower your tax by declaring a smaller price on the bill of sale. The Red Book value will take priority unless you provide an approved appraisal.

How Vehicle Appraisals Can Lower Your Ontario Car Tax

There are circumstances where the Red Book value may be too high for a vehicle in poor condition (damaged, high miles, or rusted). In those cases:

• • Obtain a written appraisal from a licensed dealer or appraiser. 
  • Send it to ServiceOntario along with your registration documents. 
  • Tax will then be based on the greater of: Your purchase price or the appraised value.

This helps avoid overpaying tax for a car that’s worth less than its listed wholesale value.

When Ontario Car Tax Is Based on Actual Sale Price

If the Red Book value is under $1,000 and the purchase price is also under $1,000:

• • The tax is charged based on the actual amount you paid.
  • You don’t need to get an appraisal.
    

This is common with very old cars or cars sold for parts.

Who Pays Tax When Buying a Used Car in Ontario?

The buyer is always responsible for paying the tax:

Dealers take care of tax collection and include it in their invoice.

In private sales, the buyer pays the tax at a ServiceOntario centre when registering the vehicle.

The seller never handles tax collection in a private sale.

Ontario Car Tax Exemptions for Used Car Purchases

Some situations allow buyers to skip the 13% tax. These include:

Family Gift Transfers

If a used car is given as a gift between close family members, you may be exempt from paying tax. Eligible relationships include:

• • Spouses
  • Parents and children
  • Siblings
  • Grandparents and grandchildren
  • Step-relatives in the same categories
    

You must submit a Sworn Statement for a Family Gift of a Used Vehicle in Ontario at ServiceOntario to claim the exemption.

Vehicles Transferred to a Reserve

If the buyer is a Status Indian and the vehicle is delivered and registered on a reserve:

• • The provincial portion (8%) may be exempt.
  • In some cases, the full 13% tax is waived.

You’ll need to present a Certificate of Indian Status and documents showing delivery on reserve land.

Diplomatic and Government Exemptions

There is a possible exemption from vehicle taxes for diplomats and certain government officials. The applicable proof of exemption must be provided when purchasing or registering the vehicle.

Other Costs When Buying a Used Car in Ontario

• • Vehicle registration fee: Approximately $32
  • Used Vehicle Information Package (UVIP): Required for private sales $20
  • Safety Standards Certificate: Required unless it was already provided, and this, depending on where you take the vehicle to get the certificate, could cost you around $100-150.

  • You can request a refund from the Ministry of Finance within 60 days of paying the tax.

Final Thoughts on Ontario Used Car Taxes
