How is a car loan payment calculated in Quebec?
Quebec car loan payments use the standard amortizing loan formula. The calculator takes your vehicle price, applies Quebec's combined 14.975% tax (5% GST + 9.975% QST), subtracts your down payment and trade-in value, then computes equal monthly payments covering principal and interest.
The formula is: M = P[r(1+r)^n] / [(1+r)^n - 1], where P is the loan amount after tax, r is the monthly interest rate, and n is the total number of payments.
Quebec has the second-highest sales tax on vehicles in Canada after the Atlantic provinces. On a $40,000 car, you pay $5,990 in combined GST + QST. However, Quebec compensates with the strongest consumer protection laws in the country, including a legal warranty that covers every vehicle purchase.
How do GST and QST apply to car purchases in Quebec?
Quebec charges two separate taxes on vehicle purchases: 5% federal GST and 9.975% provincial QST. Since 2013, QST is calculated on the price before GST (not on price plus GST), making the effective combined rate 14.975%.
For dealer purchases, the dealer collects both taxes. Trade-in value reduces the taxable amount: if you buy a $40,000 car and trade in for $10,000, you pay tax on $30,000 instead ($4,493 vs $5,990).
Private sales work differently. You pay QST (but not GST) at the SAAQ when you register the vehicle. The QST is calculated on the sale price or the estimated value from the Canadian Red Book, whichever is higher. This prevents under-reporting the sale price to reduce tax.
| Purchase type | GST (5%) | QST (9.975%) | Total tax rate | Tax on $40,000 |
|---|---|---|---|---|
| New car (dealer) | Yes | Yes | 14.975% | $5,990 |
| Used car (dealer) | Yes | Yes | 14.975% | $5,990 |
| Used car (private sale) | No | Yes (on higher of price or estimated value) | 9.975% | $3,990 |
| Gift (immediate family) | No | Exempt | 0% | $0 |
What is Quebec's garantie légale and why does it matter?
Quebec's Consumer Protection Act provides a garantie légale (legal warranty) on every vehicle sold by a dealer. This warranty cannot be waived, excluded, or reduced by any contract clause. It is the strongest buyer protection in Canada.
The garantie légale covers three things: the vehicle must be fit for its intended purpose, it must match the description given by the seller, and it must be free of hidden defects that would have changed the buyer's decision. If a major mechanical problem appears after purchase that existed before the sale, the dealer is responsible even if the vehicle was sold without an explicit warranty.
Dealers in Quebec cannot sell vehicles 'as-is' the way dealers in Ontario, BC, or Alberta can. Every dealer sale carries the garantie légale automatically. Private sales between individuals do not carry this protection, which is why dealer purchases offer more security in Quebec.
If a dispute arises, Quebec buyers can file a complaint with the OPC (Office de la protection du consommateur) or take the case to the Small Claims Court (up to $15,000) or the Quebec Superior Court for larger amounts.
What are current car loan rates in Quebec?
Quebec car loan rates in 2026 range from 4.49% for borrowers with excellent credit to 29.99% for subprime. The average rate for new vehicles is about 6.9%, and used vehicles average 8.5% to 10%.
Desjardins dominates the Quebec auto lending market. As Canada's largest federation of credit unions with over 4.5 million members in Quebec, Desjardins offers competitive auto loans with flexible terms through its extensive caisse network. Many Quebec dealers have preferred financing arrangements with Desjardins.
Quebec also has two province-based banks: National Bank of Canada (Banque Nationale) and Laurentian Bank (Banque Laurentienne), both headquartered in Montreal. National Bank offers auto loans through its dealer network, while Laurentian Bank serves the personal lending market. The five major national banks also operate across Quebec.
| Credit tier | Score range | Typical rate (new) | Typical rate (used) |
|---|---|---|---|
| Excellent | 750+ | 4.49% - 6.49% | 6.49% - 8.99% |
| Good | 660 - 749 | 5.99% - 8.99% | 7.99% - 11.99% |
| Fair | 560 - 659 | 8.99% - 14.99% | 10.99% - 17.99% |
| Poor | 300 - 559 | 14.99% - 29.99% | 16.99% - 29.99% |
What do you need to buy a used car in Quebec?
Quebec requires a mechanical inspection only in specific cases: vehicles stored for 1+ year, rebuilt vehicles, and vehicles coming from outside Quebec. Standard private sales between Quebec residents do not require a mandatory inspection, but getting one is strongly recommended.
All vehicle transfers in Quebec go through the SAAQ (Société de l'assurance automobile du Québec). The seller must provide proof of ownership and a lien-free certificate. The buyer pays QST at the SAAQ during registration.
Before buying used in Quebec, search the RDPRM (Registre des droits personnels et réels mobiliers) for liens. The RDPRM is Quebec's equivalent of the Personal Property Registry in other provinces. A VIN search costs only $4 online at rdprm.gouv.qc.ca. If a hypothec (lien) exists, the previous lender can seize the vehicle.
Quebec's Roulez Vert program offers up to $4,000 in provincial rebates for new electric vehicles in 2025 (dropping to $2,000 in 2026, and ending entirely in 2027). Combined with the federal $5,000 EVAP rebate, Quebec EV buyers can save up to $9,000 in 2025.
| Requirement | Cost | Who provides it | Why it matters |
|---|---|---|---|
| RDPRM lien search (VIN) | $4 per search | rdprm.gouv.qc.ca | Confirms no outstanding hypothecs on the vehicle |
| Mechanical inspection (stored/rebuilt/imported only) | $100 - $200 | SAAQ-authorized agent | Not required for standard private sales within Quebec |
| SAAQ vehicle registration | ~$240/year + municipal fees | SAAQ service point | Includes registration; municipal transit surcharge varies |
| QST on private sale | 9.975% of sale price or estimated value | SAAQ at registration | Calculated on the higher of sale price or Red Book value |
Worked example: financing a used car in Montreal
Sophie is buying a 2021 Hyundai Tucson from a dealer in Montreal for $30,000. She has $6,000 for a down payment and a trade-in worth $5,000. Her credit score is 700 and Desjardins offers her 7.9% over 60 months.
Step 1: Tax calculation. The taxable amount is $30,000 - $5,000 (trade-in) = $25,000. GST at 5% = $1,250. QST at 9.975% = $2,494. Total tax: $3,744.
Step 2: Loan amount. Vehicle ($30,000) + tax ($3,744) - down payment ($6,000) - trade-in ($5,000) = $22,744.
Step 3: Monthly payment. Using the amortization formula at 7.9% for 60 months, Sophie's monthly payment is $460.
Step 4: Total cost. Over 60 months Sophie pays $27,600 total, which is $4,856 in interest. Her bi-weekly payment would be $212.
Because Sophie bought from a dealer in Quebec, the garantie légale applies automatically. If a major hidden defect appears in the first months, the dealer must repair or compensate her regardless of any warranty clause in the contract.
How to get the best car loan rate in Quebec
Get pre-approved through Desjardins before visiting a dealer. As Quebec's largest lender, Desjardins offers online pre-approval and competitive rates. If you are already a member of a caisse populaire, you may qualify for preferred rates.
Buy from a dealer to benefit from the garantie légale. Private sales are cheaper (no GST, lower QST base), but you lose Quebec's strongest consumer protection. If the vehicle has a hidden defect, a dealer must fix it; a private seller does not.
Budget for Quebec's higher tax when comparing prices. A $35,000 car costs $5,241 in tax in Quebec vs $4,550 in Ontario and $1,750 in Alberta. Factor this into your loan amount and monthly payment calculation.
If buying electric, apply for the Roulez Vert rebate ($7,000 for new EVs) before or at the time of purchase. Combined with the federal $5,000 EVAP rebate, a $45,000 EV effectively costs $33,000 before tax.
