Business Vehicle Tax Deduction in Canada 2025

Using a vehicle for business in Canada entitles you to deduct a portion of your vehicle costs — but the rules are detailed and the CRA watches vehicle claims closely. Whether you drive a personal vehicle for occasional business trips or own a dedicated business vehicle, this guide explains exactly how to calculate and claim your 2025 vehicle deduction.

Two Types of Vehicle Expenses

There are two categories of deductible vehicle costs:

Operating expenses — ongoing costs to run the vehicle (gas, insurance, maintenance, parking, licence fees)
Capital cost (CCA) — depreciation of the vehicle's purchase cost over time

Both are deducted proportionally based on your business-use percentage.

Business-Use Percentage: The Mileage Log

The CRA requires a mileage log to support any vehicle deduction. Your log must record:

Date of each trip
Destination and purpose of trip
Kilometres driven
Odometer readings at start and end of year

Business-use % = Business kilometres ÷ Total kilometres driven in the year

Commuting Is Not Business Use: Driving from your home to your regular place of business is considered personal commuting — not deductible. Business use includes driving to client sites, meetings, job sites, and other business locations outside your regular workplace.

CRA Vehicle Cost Limits (2025)

The CRA caps the cost of a passenger vehicle for CCA and leasing purposes:

Limit Type	2025 Limit
Maximum capital cost for CCA (Class 10.1)	$37,000 + HST/GST/PST
Maximum monthly lease cost deductible	$1,050/month + HST/GST/PST
Maximum interest on vehicle loan (deductible)	$350/month

These limits apply to "passenger vehicles" (personal-use vehicles). Vehicles designed primarily for business use (vans, trucks over 3,000 kg GVW) typically fall in Class 10 with no cost cap.

CCA Classes for Business Vehicles

CCA Class	Vehicle Type	Rate	Cost Cap
Class 10	Most business vehicles (trucks, vans, SUVs used primarily for business)	30% declining balance	No cap
Class 10.1	Passenger vehicles costing over the limit ($37,000)	30% declining balance	$37,000 + tax
Class 54	Zero-emission passenger vehicles	100% (immediate expensing)	$61,000 + tax
Class 55	Zero-emission taxis and ride-share vehicles	100%	No cap

Half-Year Rule

In the year you purchase a vehicle, only 50% of the normal CCA rate is allowed (the "half-year rule"). So a Class 10 vehicle purchased mid-year allows 15% CCA in year 1, then 30% in subsequent years on the declining balance.

Operating Expense Deductions

Deductible operating expenses (multiplied by your business-use %):

Gasoline and diesel
Oil changes and routine maintenance
Tires and repairs
Car insurance (business portion)
Licence and registration fees
Car washes
Parking (for business trips)
Auto club memberships (e.g., CAA)

Leasing vs. Buying: Tax Implications

Factor	Buying	Leasing
Deduction method	CCA (depreciation)	Lease payments (capped at $1,050/month)
HST/GST ITCs	Claim on purchase price	Claim on each monthly payment
Cost cap	$37,000 for Class 10.1	$1,050/month lease payment cap
Flexibility	Own the vehicle outright	Return or upgrade easily
Cash flow	Higher upfront	Lower monthly

Automobile Standby Charge and Operating Benefit

If your corporation owns a vehicle and you use it personally, the CRA requires you to include a taxable automobile benefit on your T4 slip:

Standby charge: 2% per month of the original cost of the vehicle (or 2/3 of monthly lease payments)
Operating benefit: $0.33 per km of personal use in 2025

If you drive the vehicle more than 50% for business and keep a mileage log, the standby charge can be reduced proportionally.

Best Practice: If you use your vehicle more than 90% for business, consider having your corporation own the vehicle outright. If business use is lower, it may be more efficient to own the vehicle personally and charge the corporation a per-km rate or be reimbursed for actual expenses.

Simplified Logbook for Long-Term Users

If you've maintained a full mileage log for a base year and established your business-use percentage, you can use a simplified logbook in subsequent years — recording only a three-month sample period every five years, provided your vehicle use hasn't changed significantly. This reduces the administrative burden without losing your deduction.
