Company vehicle tax comes down to who is using the car. If your employer hands you a car and you drive it for personal trips, the CRA treats that as a taxable benefit on your T4. For a car the employer owns, the main piece is 2% of its cost for every month it’s available to you.
How is the benefit for an employee worked out?
There are two parts. The first is the standby charge, which pays for the fact that the car is there for you to use. The CRA formula for an owned car is cost times 2% times the number of 30-day periods it was available. For a leased car it uses two thirds of the lease cost instead. The CRA’s employers’ guide to taxable benefits and allowances sets out both parts.
The second is the operating expense benefit, which applies when your employer pays for gas, insurance or repairs that cover your personal driving. The fixed rate for 2026 is 34 cents for each personal kilometre, or 31 cents if your job is selling or leasing cars. There’s an option to use half the standby charge instead, but only if you drive the car mainly for work and tell your employer in writing before year end.
You can cut the standby charge if the employer required you to have the car, more than half your driving is for work, and your personal driving stays under 1,667 km per 30-day period. You can also lower the operating benefit by paying the employer back within 45 days after year end.
What does a company car add to your tax bill?
Take a $40,000 car, available all year, with 8,000 personal kilometres. The standby charge is $9,600 (2% of $40,000, twelve times). The operating benefit is $2,720 (8,000 km at 34 cents). The total taxable benefit is $12,320.
That’s added to your income like pay. We ran it through the income tax calculator maths for Ontario, on income tax only, and the extra tax depends on where you sit.
| Taxable income before the benefit | Extra income tax on $12,320 |
|---|---|
| $60,000 | about $3,733 |
| $80,000 | about $3,653 |
| $120,000 | about $5,348 |
The $80,000 figure is a little lower than $60,000 because the Ontario health premium changes in bands. Check your own case with the marginal tax rate calculator. The table covers income tax only, so any CPP or EI effect isn’t in it.
Put it in everyday terms. Priya in Mississauga earns $80,000 and gets that $40,000 car. The extra tax of about $3,653 works out to roughly $304 a month, before she’s bought a single coffee on the way to a client. If she barely drives it personally, the numbers look worse, because the standby charge doesn’t care how often she turns the key.
Is a company car worth it compared with a car allowance?
Often not. A fixed benefit is the reason. You pay tax on the availability of the car even when it sits in the driveway. If you drive very little for personal reasons, the standby reduction helps. If you drive a lot, the benefit is large and you may come out ahead with your own car.
A tax-free allowance works differently. The 2026 rates for provinces are 73 cents per kilometre for the first 5,000 km and 67 cents after that. In the territories they’re 77 and 71 cents. Finance announced those as the tax-exempt allowance rates. An allowance above them, or a flat amount with no link to kilometres, is a different matter, so ask your payroll team how it would be treated. Compare the two with the car loan calculator if you’d be buying a car yourself.
What can a business deduct for its vehicles?
If you own a business and put a car in it, the tax depreciation has a ceiling. For 2026 it’s $39,000 before tax on a regular passenger vehicle (Class 10.1) and $61,000 for a zero-emission one (Class 54). A $55,000 car is treated as if it cost $39,000.
| Item, 2026 | Limit |
|---|---|
| Cost ceiling, Class 10.1 | $39,000 before tax |
| Cost ceiling, Class 54 | $61,000 before tax |
| Lease cost deduction | $1,100 per month before tax |
| Interest deduction on a loan | $350 per month |
| Operating benefit rate | 34 cents per km (31 for car sales jobs) |
GST/HST is a separate question. A business can claim input tax credits on costs tied to its commercial activity, but the vehicle specifics have their own conditions. Read the CRA page on input tax credits first, and use the HST reverse calculator to split a receipt.
What records should you keep for a company car?
A logbook, kept as you go. Note the date, the starting and ending odometer, the trip’s purpose and whether it was business or personal. Add a yearly odometer reading on 1 January and 31 December. Photos of the dashboard work fine. It takes about thirty seconds a trip, and it’s the paper that supports any reduced standby charge if the CRA asks. Without it you’re arguing from memory.
Mistakes that cost people money
The big one is poor records. The benefit leans on personal kilometres, so a logbook matters. Without one, the CRA has little reason to accept a reduced charge. Another is forgetting to tell your employer that you’re using the half-standby option before December 31.
Some owner-managers also treat the car as fully business when it isn’t. A personal share always exists if you use it to get to a job site from home or for groceries. Keep the split honest.
And remember that availability is what drives the standby charge, not how often you turn the key. A car parked at home all weekend still counts.
Where this information comes from
The benefit rules come from the CRA page on employer-provided automobiles. The 2026 limits and rates come from the Department of Finance announcement of January 2026. The tax examples use 2026 federal and Ontario brackets in our calculator. Corporate fleets have extra details, so a payroll specialist or accountant should check a real one.
Frequently asked questions
Is a company car a taxable benefit?
Yes, when an employer provides a car you can use for personal trips. The benefit has a standby part and, if the employer pays running costs, an operating part.
How is the standby charge calculated?
For an owned car it is 2% of the cost for each 30-day period the car is available. For a leased car the CRA uses two thirds of the lease cost.
What is the 2026 operating benefit rate?
34 cents per personal kilometre, or 31 cents for employees whose job is selling or leasing cars.
Is there a limit on the cost I can depreciate?
For 2026 the ceiling is $39,000 before tax for a regular passenger vehicle and $61,000 for a zero-emission one.
Can I lower the benefit?
Sometimes. A reduced standby charge needs a work requirement, over 50% business driving and low personal driving. Paying the employer back within 45 days after year end lowers the operating part.
