Should I Buy a Car Through My Corporation?
The corporation gets a capped deduction and you get a taxable benefit calculated on the full cost. Work out the classification, the deductible amount, the standby and operating benefits landing on your T4, and whether corporate ownership actually beats owning it yourself.

Disclaimer: A vehicle that meets the definition of a passenger vehicle is included in Class 10.1 where its cost exceeds the prescribed amount, and the capital cost for capital cost allowance purposes is limited to that prescribed amount; vehicles costing less are generally included in Class 10, and eligible zero-emission passenger vehicles are included in Class 54 subject to a separate and higher prescribed limit. Deductible lease costs and interest on money borrowed to acquire a passenger vehicle are also subject to prescribed limits. Input tax credits on a passenger vehicle are restricted by reference to the same capital cost limit. A standby charge arises under paragraph 6(1)(e) where an automobile is made available to an employee or shareholder, calculated for an owned vehicle at 2% of the original cost for each month of availability and for a leased vehicle at two-thirds of the lease costs, and may be reduced where the vehicle is used primarily in the course of employment and personal driving does not exceed a prescribed annual limit. An operating expense benefit arises under paragraph 6(1)(k), calculated at a prescribed per-kilometre rate on personal kilometres, or in certain circumstances by election at one half of the standby charge. The prescribed capital cost limits, lease limits, per-kilometre operating benefit rate and tax-free allowance rates are all set by regulation and change; the figures used here are defaults you should replace with the current prescribed amounts before relying on any result. Accelerated capital cost allowance incentives have applied to vehicles in some years and are phasing out, so first-year deductions may differ from the half-year calculation shown. The comparison presented is a first-year comparison only; because capital cost allowance is claimed over many years while the standby charge applies in full from the first month, a single-year view is inherently unfavourable to corporate ownership and a multi-year analysis may reach a different conclusion. Whether a vehicle is a passenger vehicle, a motor vehicle or otherwise is a question of fact turning on its design and use. This page is general information, not tax advice.
The Asymmetry That Decides It
The corporation’s deduction for a passenger vehicle is capped at a prescribed amount. Your taxable benefit is not. The standby charge is calculated on what the vehicle actually cost, including the portion the corporation was never allowed to deduct.
Buy a sixty-two thousand dollar car through the company and you may be deducting on thirty-eight while being taxed on sixty-two. The more expensive the vehicle, the worse that gap becomes, which is why corporate ownership of a costly car so often loses.
The standby charge does not care whether you drove it. It is a charge for availability, so a vehicle sitting in the corporation’s name and parked at your house generates a benefit every month regardless of use. Only the reduced standby charge, which requires primarily business use and limited personal driving, brings it down.
Three Classes, Two Caps
| Class | Applies To | Capital Cost |
|---|---|---|
| Class 10 | Passenger vehicles at or below the prescribed limit | Full cost, no cap |
| Class 10.1 | Passenger vehicles above the prescribed limit | Capped at the limit |
| Class 54 | Eligible zero-emission passenger vehicles | Capped at a higher limit |
Class 10.1 has a peculiarity worth knowing: each vehicle sits in its own separate class, and on disposal there is no recapture and no terminal loss. That is occasionally an advantage and more often just an oddity that confuses the bookkeeping.
The zero-emission limit is substantially higher than the conventional one. For an electric vehicle in the range between the two limits, the deductible amount can be most of the purchase price rather than a fraction of it, which changes the answer materially. Both limits are prescribed and both have been raised before, so confirm the current figures rather than working from an old note.
The Standby Charge
For an owned vehicle the standby charge runs at two per cent of the original cost for each month the vehicle is available to you. Over a full year that is twenty-four per cent of what the car cost, added to your employment income.
For a leased vehicle it is two-thirds of the lease costs for the period of availability. Either way it is a large number, and on a full year it usually dwarfs the operating benefit sitting beside it.
The Reduction, and Why Most People Miss It
The standby charge can be reduced where the vehicle is used primarily in the course of employment and personal driving stays within a prescribed annual limit. Both conditions have to hold, and the reduction is proportional to how far personal use falls below the threshold.
What defeats the reduction most often is not the driving. It is the absence of a log. The reduction depends on demonstrating the business proportion, and an estimate produced two years later during an audit is not evidence.
Commuting is personal. Driving from home to a regular place of work is not business use no matter how much equipment is in the back, and it is the single most common reason a claimed business percentage collapses on review. Travel between work locations during the day is a different matter.
The Operating Benefit Sits on Top
Where the corporation pays running costs, a second benefit arises on the personal share, calculated at a prescribed rate for each personal kilometre. An alternative calculation at one half of the standby charge is available by election in some circumstances, and which one is better depends on the numbers.
That rate is set by regulation and moves, so it is worth checking each year rather than carrying forward the figure from the last return.
The Alternative Almost Nobody Costs Out
Own the vehicle yourself and have the corporation pay you a per-kilometre allowance for business driving. Within the prescribed rates that allowance is deductible to the corporation and tax-free to you, and no standby charge arises at all because the corporation does not own or lease anything.
For a moderately priced car with high business mileage this frequently wins, and it wins by a wide margin on an expensive vehicle. The corporate route tends to work best where the vehicle is cheap, business use is very high, and the standby charge reduction genuinely applies.
| Situation | Usually Better |
|---|---|
| Expensive car, moderate business use | Personal ownership with an allowance |
| Modest car, very high business use | Corporate ownership can work |
| Electric vehicle within the higher limit | Corporate ownership improves |
| Vehicle mostly parked, occasional use | Personal, the standby charge is brutal |
| No mileage log kept | Personal, the reduction is unavailable anyway |
An allowance has to be reasonable. Where the per-kilometre amount exceeds what the vehicle genuinely costs to run, it can be treated as taxable income rather than a tax-free reimbursement. A high-mileage claim on a cheap car can cross that line, so the margin is not a saving to bank on.
A Van or a Pickup Can Change the Analysis
The passenger vehicle definition has exclusions, and a vehicle that falls outside it escapes both the capital cost cap and, in some cases, the standby charge regime. Certain vans, pickups and vehicles used substantially for transporting goods or equipment can qualify depending on seating and the proportion of business use.
The tests are specific and turn on the year of acquisition, the seating configuration and how the vehicle is actually used. Where a business genuinely runs a work truck, this is worth examining properly rather than assuming the passenger vehicle rules apply.
What This Calculator Does Not Cover
- Accelerated capital cost allowance incentives, which have applied in some years and are phasing out
- The prescribed lease cost and interest limits, which cap deductions separately
- Whether a van or pickup escapes the passenger vehicle definition
- Disposal, recapture and terminal loss, including the Class 10.1 treatment
- Provincial differences outside Ontario in rates and sales tax recovery
- Shareholder benefit rules where the vehicle is provided other than as an employee
- The multi-year position, since this compares the first year only and capital cost allowance runs for many
