Can my corporation pay for my car, and how is it taxed?

Two ways a corporation can cover a car, taxed very differently

A corporation can either own or lease the vehicle directly and let an employee or owner-manager use it, or it can reimburse a personally owned vehicle through a per-kilometre allowance. These two paths are taxed under completely different rules, and picking the wrong one for how you actually use the vehicle can cost real money in either direction.

Corporate ownership: the standby charge

When a corporation owns or leases a vehicle and makes it available to an employee or owner-manager who also uses it personally, even occasionally, that person is taxed on a standby charge, a taxable benefit calculated on the vehicle’s cost or lease cost regardless of how little it is actually driven personally. The standby charge is reduced only if personal use is genuinely minor and business use is high, under a specific CRA test that is stricter than most owners expect; simply saying the car is “mostly for business” without a logbook to support it is not enough to reduce the charge.

Corporate ownership: the operating benefit

On top of the standby charge, a separate operating expense benefit applies to the personal-use portion of the vehicle’s actual running costs, fuel, maintenance, insurance, and so on, calculated using a per-kilometre rate the CRA publishes each year, unless the employee reimburses the corporation for personal use within the required time. Together, the standby charge and the operating benefit are why a corporate-owned vehicle with meaningful personal use can generate a larger taxable benefit than many owners expect when they first set up the arrangement.

Depreciation limits on a corporate-owned vehicle

A corporation deducts a vehicle’s cost through capital cost allowance, typically under class 10 or the higher-cost class 10.1, which caps the amount that can be added to the pool for a passenger vehicle above a threshold the CRA updates periodically. As at the time of writing, this cap and the related lease-cost deduction limit should be confirmed against the CRA’s current-year table before finalizing a purchase or lease decision, since exceeding the class 10.1 threshold does not disqualify the deduction but does cap how much of the cost is ever recovered. A separate, generally higher, class 54 exists for zero-emission vehicles, reflecting a policy choice to encourage EV purchases through a larger available deduction.

The alternative: personal ownership with a per-kilometre allowance

Instead of the corporation owning the vehicle, many owner-managers keep the car in their own name and have the corporation pay a reasonable per-kilometre allowance for business kilometres driven, using rates the CRA publishes annually and updates from time to time; the current-year rate should be confirmed before setting a reimbursement rate. An allowance paid at or below the CRA’s reasonable rate, based on a proper log of actual business kilometres, is not a taxable benefit to the individual and is deductible to the corporation, avoiding the standby charge and operating benefit calculations entirely. This route generally works better for someone who drives modestly for business and wants to avoid the compliance burden of tracking a corporate vehicle’s personal-use benefit.

What about a truck or van used almost entirely for work

Some of the standby charge and depreciation caps described above apply specifically to passenger vehicles, a defined category that excludes certain trucks, vans, and other vehicles that seat limited passengers and are used mainly to transport goods or equipment. A contractor's cargo van or a landscaper's loaded pickup truck can fall outside these limits entirely under the right conditions, which changes both the CCA available and whether a standby charge even applies in the usual sense. Whether a specific vehicle qualifies depends on its seating, use, and how it is equipped, so this needs to be checked against the vehicle's actual specifications rather than assumed from its general type.

Why the logbook decides which method wins

Whichever method is used, a contemporaneous logbook tracking the date, destination, purpose, and kilometres of each business trip is what actually supports the numbers on audit, whether that is reducing a standby charge, substantiating an operating benefit reimbursement, or backing up a per-kilometre allowance claim. Owners who reconstruct mileage from memory at year-end consistently end up with weaker support than those who log trips as they happen, and a logbook kept for a representative sample period can sometimes be used to project a full year, under specific CRA conditions.

GST/HST and the vehicle itself

A corporation that owns a vehicle used in commercial activity can generally claim input tax credits on the GST/HST paid to buy or lease it, subject to the same class 10.1 cost cap that limits the CCA deduction, and subject to a reduction where the vehicle also has personal use. This is a separate calculation from the standby charge and operating benefit, worked out under the same mechanics we cover in how input tax credits work, so the vehicle decision genuinely touches both income tax and GST/HST at once rather than one or the other.

How we handle this

We run the numbers both ways using a client’s actual business-versus-personal mileage split before recommending corporate ownership or a per-kilometre allowance, and we set up a simple logbook system so the chosen method has the documentation it needs if the CRA ever asks. This is part of our bookkeeping and corporate tax work for incorporated clients.
