An incorporated IT contractor who needs a vehicle for business travel has three ways to structure it: the corporation owns or leases the vehicle directly, the corporation pays the contractor a per-kilometre allowance for using a personally owned vehicle, or the contractor claims vehicle expenses personally as an employee expense on Form T777. Each route has a different tax result, and mixing them for the same vehicle in the same year creates problems. The right choice depends on how much personal use the vehicle gets and how the corporation’s compensation is structured, not on which route feels most familiar from a prior sole proprietorship.
Why the Corporate Context Changes the Analysis
A sole proprietor deducting vehicle expenses under Form T2125 is claiming against their own business income, and the vehicle, however it is used, belongs to them personally. An incorporated contractor is a separate legal entity from the corporation, and the vehicle question becomes a question of which entity owns the vehicle and whether the shareholder-employee’s personal use of a corporate asset creates a taxable benefit.
This is the same separation-of-entities issue that runs through most incorporated contractor expense questions, covered generally in the owner-paid expenses and corporate credit cards guide. Vehicles add an additional layer because CRA has specific benefit-calculation rules, the standby charge and operating cost benefit, that apply only to employer-provided automobiles and do not have an equivalent for other mixed-use corporate assets.
Route 1: Corporate-Owned or Leased Vehicle
When the corporation owns or leases the vehicle, the corporation claims CCA (for an owned vehicle) or lease payments (for a leased vehicle), along with fuel, insurance, maintenance, and other operating costs, subject to the same prescribed limits that apply to any taxpayer.
Prescribed limits apply to the corporation
Passenger vehicles fall under CCA Class 10.1, which carries a prescribed maximum capital cost for CCA purposes, a prescribed maximum deductible lease cost per month, and a prescribed maximum deductible loan interest per month. These limits are reviewed periodically and can change from year to year; the corporation’s bookkeeper should confirm the limit in effect for the vehicle’s acquisition or lease year, since a vehicle acquired in one year keeps that year’s prescribed capital cost limit for CCA purposes even if the limit changes in later years. Work trucks and certain commercial vehicles used primarily for business can fall under Class 10 instead, without the same passenger-vehicle limits, depending on the vehicle’s configuration and use.
The standby charge and operating cost benefit
If a shareholder-employee has personal use of a vehicle owned or leased by the corporation, two benefit calculations generally apply. The standby charge reflects the benefit of having the vehicle available for personal use, calculated as a percentage of the vehicle’s cost or lease cost, reduced if business use is high enough and personal kilometres are low enough to qualify for the reduced-standby-charge test. The operating cost benefit reflects the personal portion of operating costs like fuel, insurance, and maintenance, generally calculated using a prescribed per-kilometre rate for personal kilometres driven, unless the employee elects to use a percentage of actual operating costs instead where that election is available.
Both benefits are included in the shareholder-employee’s personal income and are subject to payroll withholding in the same way as other taxable benefits. A corporation providing a vehicle to an owner-employee with meaningful personal use should expect this benefit calculation every year the vehicle is provided, not just at year-end reconciliation. Where business use is close to 100% and personal use is minimal and well documented with a logbook, the standby charge reduction can bring the taxable benefit down substantially, but it does not eliminate it entirely without a logbook supporting the low personal-use claim.
When corporate ownership makes sense
Corporate ownership is most straightforward when the vehicle’s use is overwhelmingly business, personal use is minor and logged, and the corporation is comfortable administering the standby charge and operating benefit calculation through payroll each year. A contractor who drives extensively for client site visits, equipment delivery, or similar business purposes, with a separate personal vehicle for family use, is the clearer case for corporate ownership.
Route 2: Per-Kilometre Allowance on a Personal Vehicle
The corporation can pay the shareholder-employee a per-kilometre allowance for business use of a personally owned vehicle. Where the allowance is based on business kilometres actually driven and uses CRA’s current prescribed per-kilometre rate, it is generally not included in the employee’s income and the corporation deducts the allowance paid as a vehicle expense. CRA publishes the prescribed rate for the year on its automobile allowance rate page; the rate is reviewed annually and the current year’s figure should be confirmed rather than assumed from a prior year.
A logbook recording the date, destination, purpose, and kilometres of each business trip is required to support the allowance, since the tax-free treatment depends on the allowance being reasonable and tied to actual business kilometres, not a flat monthly amount unrelated to use. A flat monthly car allowance with no logbook and no connection to actual kilometres driven is generally treated as taxable income to the employee rather than a tax-free allowance.
This route keeps the vehicle entirely outside the corporation. The contractor owns, insures, and maintains the vehicle personally, and the corporation’s only vehicle-related cost is the allowance paid, which is simpler from a bookkeeping perspective than tracking CCA, standby charges, and operating benefits on a corporate vehicle.
Route 3: Employee Expense Claim on T777
Instead of an allowance, the contractor can claim vehicle expenses personally on Form T777 as an employee, using a signed T2200 confirming they were required to use a vehicle for employment duties and were not fully reimbursed through a tax-free allowance. The employee vehicle expense calculation prorates fuel, insurance, maintenance, licence and registration fees, CCA, and loan interest, all subject to the same prescribed limits described above, by the business-use percentage established through a logbook.
This route and the allowance route are mutually exclusive for the same costs: an employee who has already received a tax-free per-kilometre allowance covering their business driving cannot also claim vehicle expenses on T777 for the same use. Where the corporation pays a partial allowance that does not fully cover the reasonable cost of business use, or pays no allowance at all, the T777 route lets the contractor claim actual costs instead, subject to the logbook and documentation requirements.
Choosing Between the Three Routes
| Corporate-owned vehicle | Per-kilometre allowance | Employee T777 claim | |
|---|---|---|---|
| Best fit | Heavy, well-documented business use; minimal personal use | Personally owned vehicle, moderate business use | Personally owned vehicle, no allowance paid or a partial allowance |
| Corporate deduction | CCA, lease, and operating costs, per business-use percentage | Allowance paid, using CRA’s prescribed rate | None; costs claimed on the employee’s personal return |
| Personal tax exposure | Standby charge and operating benefit for personal use | None if allowance is reasonable and logbook-supported | None beyond the deduction itself; reduces employment income |
| Logbook required | Yes, to support the reduced standby charge and business-use percentage | Yes, to support the allowance as reasonable | Yes, to support the business-use percentage |
The comparison depends heavily on how much personal use the vehicle actually gets and how compensation is otherwise structured between salary and dividends. A contractor with a vehicle used almost entirely for business, where compensation planning already favours corporate deductions, may prefer corporate ownership. A contractor whose vehicle sees substantial personal use is usually better served keeping it out of the corporation entirely and using the allowance or T777 route.
Logbook Requirements Across All Three Routes
Every route depends on a logbook. CRA requires the total kilometres driven and business kilometres driven to be documented, with each business trip recorded by date, destination, purpose, and kilometres. CRA does accept a simplified logbook after a full base-year logbook establishes a consistent usage pattern, but a first-year vehicle claim, in any of the three routes, should start with a complete logbook.
Odometer readings at the start and end of the year support the total-kilometres figure used in the business-use percentage calculation. Without odometer readings, the business-use percentage cannot be verified even where individual trips are logged.
Documentation to Keep
- logbook records: date, destination, purpose, and kilometres for each business trip
- annual odometer start and end readings
- receipts or statements for fuel, insurance, maintenance, and licensing
- for a corporate-owned or leased vehicle, the CCA schedule, lease agreement, and the standby charge and operating benefit calculation for each year of personal use
- for an allowance, a record of the rate used and confirmation it matches CRA’s prescribed rate for that year
- for a T777 claim, the signed T2200 and the same expense receipts and logbook records described above
Retain these records for six years from the end of the taxation year to which they relate.
