Quick answer: If your corporation owns or leases a vehicle that you also use personally, CRA generally treats that personal use as a taxable benefit made up of two parts: a standby charge, based on the vehicle's cost and how much it was available to you personally, and an operating benefit, based on the personal-use share of actual running costs. Together they can add up to a meaningful amount added to your personal income each year — which is why a company car isn't automatically the most tax-efficient way to get a vehicle into your life, and why a logbook is essential if you go this route.
Key takeaways
- A corporate-owned vehicle used personally generally triggers two taxable benefits: a standby charge and an operating benefit.
- The standby charge applies based on availability for personal use, not just actual personal kilometres driven.
- The operating benefit reflects the personal-use share of costs like fuel, insurance, and maintenance.
- A detailed logbook is usually the only way to support a reduced benefit calculation.
- A per-kilometre allowance paid to the owner personally is often simpler and more tax-efficient than a company car with heavy personal use.
Putting a vehicle in the corporation's name feels like a natural extension of running a business — the company pays for it, the company deducts it, done. But when the owner or an employee also drives that vehicle personally, CRA doesn't let the personal benefit pass through untaxed. Two separate concepts come into play, and together they often surprise owners who assumed a "company car" was simply a business deduction with no personal tax consequence.
The standby charge, conceptually
The standby charge exists to tax the value of having a vehicle available for personal use, regardless of how much it's actually driven personally. It's calculated with reference to the vehicle's cost (or lease cost) and the proportion of the time it was available for personal use versus used primarily for business. The key word is "available" — even a vehicle that mostly sits in the driveway on weekends can generate a standby charge if it wasn't genuinely restricted to business use during that time. A lower business-use percentage generally increases the standby charge; a consistently high business-use percentage, properly documented, can reduce it.
The operating benefit, conceptually
Separately from the standby charge, the operating benefit taxes the personal-use share of the actual costs the corporation paid to run the vehicle — fuel, insurance, maintenance, and similar expenses. It's calculated differently from the standby charge, and both benefits can apply to the same vehicle in the same year. In some circumstances an employee can elect to have the operating benefit calculated based on actual personal operating costs rather than the standard method, but that election has its own conditions and isn't automatically available.

Why a logbook matters so much here
Both the standby charge and the operating benefit hinge on being able to show how the vehicle was actually used. A contemporaneous logbook — recording the date, destination, purpose, and kilometres of each trip — is generally the only reliable evidence available if CRA questions the business-use percentage claimed or the reduced benefit calculated. Without one, CRA can fall back on less favourable assumptions, and reconstructing a year's worth of driving from memory after the fact rarely holds up well in a review.
Company car vs. a per-kilometre allowance
A corporation isn't required to own the vehicle its owner drives. An alternative is for the individual to own their personal vehicle and have the corporation pay a reasonable per-kilometre allowance for the business portion of its use — an approach that avoids the standby charge and operating benefit calculations entirely, because the corporation never owns the asset being used personally. Whether that's better than a company car depends heavily on how much of the vehicle's use is genuinely personal. A vehicle that's driven almost entirely for business may make more sense owned by the corporation; one with substantial personal use often comes out ahead as a mileage-reimbursed personal vehicle instead. We compare these mechanics in more detail in our guide to vehicle and mileage deductions.
The bottom line
A company car isn't a tax-free perk — it's a deduction for the corporation offset by a taxable benefit to the person using it personally, calculated through the standby charge and operating benefit rules. Before putting a vehicle in the corporation's name, it's worth running the numbers against the alternative of a personally owned vehicle with a mileage allowance, and committing to a real logbook either way.
