Should You Put a Passenger Vehicle in Your Corporation?

Understanding the Tax Rules

For many small business owners in Canada, it feels natural to ask: Should I own my car through my corporation? After all, the company already pays for office rent, computers, and supplies—so why not the vehicle you use for work?

The answer: it depends. When it comes to passenger vehicles (cars and SUVs with four or more seats), Canadian tax rules impose strict limits. And as a recent Québec Court case—2025 QCCQ 1391 (CanLII)—reminds us, failing to handle these correctly can turn a convenience into an expensive mistake.

1. Passenger Vehicles vs. Business Vehicles

Not all vehicles are treated the same way.

• Passenger vehicles (most cars and SUVs): Subject to specific tax restrictions.
• Business vehicles (trucks, vans, or vehicles with fewer than four seats used primarily for business): More generous rules apply, since these vehicles aren’t expected to be used for commuting or personal errands.

This article focuses on passenger vehicles, since that’s where the pitfalls lie.  All amounts listed are effective 1 January 2025.

2. The Main Tax Issues With Passenger Vehicles in a Corporation

Here’s what you need to know if you’re considering holding a passenger vehicle inside your company:

a) Capital Cost Allowance (CCA) Limitations

Depreciation (CCA) on passenger vehicles is restricted:

• Only the first $38,000 (plus tax) of the purchase price can be depreciated (Class 10.1).
• If you buy a luxury car worth $60,000, you only get tax depreciation on $38,000—the rest is ignored for corporate tax purposes.

b) Lease Deduction Limits

If your corporation leases the vehicle instead of buying it, deductions are limited to about $1100 per month (plus tax). Anything above that isn’t deductible.

c) Interest Deduction Limits

If the company finances the car, deductible interest is capped at $350 per month—even if your loan costs more.

d) Personal Use Charges (Standby Charges & Operating Benefits)

When a passenger vehicle is available for your personal use (e.g., evenings, weekends, or commuting):

• A standby charge applies, generally 2% of the cost of the vehicle per month (or 24% per year).
• Additional operating benefit is calculated if the company pays for fuel and running costs (currently 33% of personal kilometers).
• These amounts are reported as taxable benefits on your T4, increasing your personal income.

The rules mean that even if the vehicle is mostly for business, simply making it available to you can trigger these taxable charges.  These are added to your personal income, at your marginal personal tax rate – not the lower small business tax rate!  These personal use charges apply even if your expenses are limited or disallowed.  You could be in the awkward position of having to pay personal tax on something that you got no or limited business tax deduction!

3. What the Court of Québec Said in 2025 QCCQ 1391

In the case of 2025 QCCQ 1391, the Court reviewed a situation where a corporation held a passenger vehicle but failed to properly apply the tax rules.

The Court confirmed two key points:

1. Ownership through a corporation doesn’t remove personal benefit: If the car is available to a shareholder or employee personally, standby charges and operating benefits must be calculated.
2. Business purpose must be clear and documented: Without proper agreements and records, corporate deductions can be reduced or denied, and benefits reassessed as shareholder advantages.

The judgment is a reminder that you can’t “hide” a personal car in your corporation. If you want the company to own it, you must follow the rules and report the benefits correctly.  The rules in Quebec are even stricter than Federal rules – but the key principles are the same.

4. Passenger Vehicle Ownership: Personal vs. Corporate

Here’s a quick comparison to help you decide:

Factor	Personal Ownership (with mileage reimbursement)	Corporate Ownership
Upfront Costs	You buy the car personally. The company reimburses you for business km using CRA’s reasonable rate ($0.72/km first 5,000 km, $0.66/km after).	The corporation pays for purchase or lease, insurance, maintenance, and fuel.
Tax Deductions	Corporation deducts only mileage reimbursements. No limits, no calculations—rates are designed to cover fuel, insurance, depreciation, repairs.	Deduction limits apply: • Max $38,000 of purchase price depreciable (CCA) • Lease limited to ~$1150/month • Interest capped at $350/month.
Personal Income Impact	No taxable benefit to you personally. Reimbursements at CRA’s rate are tax-free.	Taxable benefit arises if car is available for personal use: • Standby charge (up to 24% of cost annually) • Operating benefit (33% of personal km if company pays fuel).
Cash Flow	You carry operating, financing and insurance costs personally. Company only pays mileage cheques.	Company covers costs directly—helpful if corporate cash flow is stronger than personal.
Administration	Simple: track business km (logbook or app).	Complex: must calculate standby charges, keep mileage logs, track split between personal and business use.
Best For…	Owners with higher-cost cars or primarily personal use; those who want simplicity and no taxable benefits.	Modest-cost cars with very high business use; situations where corporate cash flow is preferred.

Key Takeaways

• Passenger vehicles in corporations are heavily restricted—with caps on depreciation, leasing, and interest deductions.
• Personal use triggers standby charges and operating benefits, even if the business pays most of the expenses.
• The Court of Québec (2025 QCCQ 1391) reaffirmed that courts will enforce these rules strictly.
• For many owners, it’s simpler (and often cheaper) to keep the car personal and charge the corporation per kilometer.

Bottom line: Don’t just drop your car into the company because it “feels easier.” Run the numbers, understand the limits, and get advice before making the move. In most cases, the corporate route only pays off for lower-cost vehicles with very high business use.
