Do You Pay Tax on Used Vehicles in Saskatchewan?

If you buy a used vehicle in Saskatchewan, you pay 6% Provincial Sales Tax on the higher of your purchase price or the vehicle’s Canadian Red Book value, and if the seller is a dealership you also pay 5% federal GST on top. That is the default rule for tax on used vehicles in Saskatchewan. A handful of exemptions change the picture: private sales at or below $5,000, gifts between qualifying family members, and vehicles brought in by new residents can be tax-free.¹

Dealerships collect PST at the point of sale. On private purchases, the motor licence issuer collects PST when you register the vehicle. On a dealer sale, PST is calculated on the total selling price, including documentation fees, freight, and dealer-installed accessories. GST is not part of the PST base, but federal luxury tax is.²

How the Taxable Value Is Set

The province does not simply take the number written on your bill of sale. For private sales, the motor licence issuer compares your purchase price to the vehicle’s Canadian Red Book average retail price at the time of registration and charges 6% on whichever is higher. The Red Book is a valuation guide published by Carfax Canada and used across the country by governments, insurers, and lenders.³

The rule exists to stop buyers and sellers from writing down the price to reduce the tax bill. If you genuinely paid less than Red Book value because the vehicle has damage, high mileage, or other condition issues, you can challenge the valuation. Supporting evidence goes to the Ministry of Finance: the bill of sale, current odometer reading, photos of damage, and either an SGI safety inspection or a repair quote from a third-party shop.¹

You have two routes. You can submit your evidence to Finance before registering and request a letter authorizing PST on your actual purchase price. Or you can pay the full amount at registration based on Red Book value and then apply for a refund of the difference. Pre-authorization saves you from waiting on a refund, so it is worth pursuing if your documentation is ready.

The $5,000 Private-Sale Exemption

Private purchases of used vehicles valued at $5,000 or less are exempt from PST. The catch that trips up buyers: both the purchase price and the Red Book value have to be at or below $5,000. If the Red Book says the vehicle is worth $5,500 even though you paid $4,000, the exemption does not apply, and you owe 6% PST on $5,500.¹

When the vehicle does qualify, you present your bill of sale at registration and no PST is collected. Dealer sales do not qualify — the exemption applies only to transactions between private individuals.

How Trade-Ins Interact

A trade-in reduces the amount you pay PST on, but the $5,000 threshold is checked before the trade-in is deducted. If the purchase price (or Red Book value) exceeds $5,000, the exemption is gone, and you pay 6% on the net price after subtracting the trade-in — even if that net drops below $5,000.

Take a $7,000 vehicle with a $3,000 trade-in. The exemption is unavailable because the price exceeds $5,000, but PST applies to $4,000 rather than $7,000, saving you $180. The trade-in has to happen within the same transaction; you cannot trade at one dealer and claim the credit at another.

Family Gifts and Transfers

A vehicle gifted between qualifying family members can be exempt from PST, but two conditions apply: the vehicle must be for personal, non-business use, and it must be Saskatchewan tax-paid, meaning PST was previously paid on it in the province or it qualified for a prior exemption such as settler’s effects.³

If the donor bought the vehicle in another province and PST was never paid here, the exemption for tax-paid vehicles is unavailable. PST then applies on the higher of Red Book value or purchase price when either exceeds $5,000. The $5,000 rule still helps if both figures fall at or below that threshold.

Qualifying family members include:

Spouse or common-law partner, including same-sex partners
Parents and children, including step-parents and step-children
Grandparents and grandchildren, including step-grandparents and step-grandchildren
Siblings, including step-brothers and step-sisters
In-laws: mother-in-law, father-in-law, son-in-law, daughter-in-law
Legal guardians and foster parents

The exemption also covers transfers arising from a divorce or legal separation settlement. The donor writes a letter stating the family relationship and confirming the transfer is a gift, and the recipient presents it at registration.

A related rule covers low-value family sales. If a qualifying family member sells you a tax-paid vehicle below Red Book value, PST is calculated on the actual selling price rather than the Red Book figure. If the sale price is $5,000 or less, no PST applies.

GST on Dealer Purchases

Buy from a dealership or any other GST-registered business and 5% federal GST is added to the price on top of the 6% PST. The combined tax on a dealer purchase is 11%. Private sales between individuals who are not registered for GST do not attract the federal tax.⁴

If the vehicle is for business use and your business is GST-registered, you can recover some or all of the GST through Input Tax Credits. The credit tracks commercial use: full credit at 90% or more, a proportional credit between 10% and 90%, and nothing at 10% or less.⁵

Vehicles From Outside Saskatchewan

PST applies to any vehicle purchased outside the province and brought here for use, including gifts from out-of-province donors. If the seller did not collect Saskatchewan PST, SGI collects it at registration.⁶

New Residents

Moving to Saskatchewan can qualify you for the settler’s effects exemption, which waives PST on personal vehicles you bring with you. The requirements are specific:

You lived outside Saskatchewan full-time for at least six months
You bought the vehicle before your move and it has been registered in your name (or supported by a bill of sale) for at least 30 days before your arrival
The vehicle was a personal-use vehicle in your previous jurisdiction and remains one here; business assets and leased vehicles do not qualify
Joint ownership works as long as at least one of the original owners registers the vehicle in Saskatchewan

Farm-plated light vehicles such as half-tons, vans, and SUVs may qualify if they are primarily for personal use. Farm semis, trailers, and grain trucks do not.⁷

Status Indian Purchases

A Status Indian buyer can purchase a vehicle PST-free if the vendor (or a third-party carrier the vendor arranges) delivers it to a reserve. The buyer presents a Certificate of Indian Status card, and the vendor records the full 10-digit card number on the sales invoice. If the buyer takes possession off-reserve, PST applies regardless of status.⁸

Paying the Tax at Registration

You pay PST at a motor licence issuer (an SGI-authorized office) when you register the vehicle. Bring:

A bill of sale showing the date, full names and addresses of buyer and seller, the year, make, model, and VIN, the purchase price, and both signatures
A gift letter from the donor stating the relationship, if the vehicle is a qualifying family gift
Photos of damage, the odometer reading, and a repair quote or safety inspection, if you are challenging the Red Book value
The authorization letter from Finance, if pre-approval for a lower valuation has been granted

The issuer calculates PST from your documentation and the Red Book value, then collects payment before completing the registration.

What Happens If PST Goes Unpaid

Most buyers never face penalties because the motor licence issuer collects PST at registration and you cannot register without paying. The risk shows up if you drive a vehicle unregistered or fail to disclose one you brought into the province. The Ministry of Finance charges interest on unpaid tax at prime plus 3%, which works out to 7.95% for the first half of 2026.⁹

If extraordinary circumstances such as a medical emergency or natural disaster prevented timely payment, you can apply to have penalties or interest waived through the Ministry of Finance’s Penalty and Interest Waiver Application. Approval is not guaranteed.¹⁰
