Understanding which vehicle expenses CRA allows you to deduct can save you thousands of dollars at tax time. Whether you are self-employed, an employee who drives for work, or a commission salesperson covering your own territory, the Canada Revenue Agency permits deductions for fuel, insurance, maintenance, lease payments, loan interest, capital cost allowance, registration, and parking. The catch is that only the business-use portion of each cost qualifies.
This pillar guide covers every eligible vehicle expense category, the 2026 deduction limits, how the business-use calculation works, which tax form to file, and what records you need to survive a CRA review.
How Business-Use Percentage Determines Your Deduction
The CRA never lets you write off 100 percent of your vehicle costs simply because you drive for work. Instead, every expense is multiplied by your business-use percentage:
Business-use % = Business kilometres / Total kilometres driven in the tax year
You apply that single ratio to every eligible cost. Personal driving, including your daily commute, does not count.
Example: You drove 20,000 km in 2026. Of that total, 14,000 km were for business purposes. Your business-use percentage is 70 percent. If your total eligible vehicle expenses for the year were $18,000, your deduction is $18,000 times 70 percent, which equals $12,600.
The accuracy of that percentage depends entirely on your mileage log. A single missed business trip lowers the ratio and shrinks your deduction. Tripbook records every trip with GPS verification, so your business-use percentage reflects the reality of how you drive.
Every Eligible Vehicle Expense You Can Claim
The CRA groups deductible motor vehicle expenses into several categories. Below is the complete list along with the 2026 limits that apply.
Fuel and oil. Gasoline, diesel, or electricity charging costs are fully eligible. Track every fill-up or charging session and keep receipts.
Insurance. Your annual vehicle insurance premium qualifies. The deductible portion is your premium multiplied by your business-use percentage.
Maintenance and repairs. Oil changes, tire replacements, brake work, transmission service, and other mechanical repairs count. Cosmetic work like detailing qualifies only when it is directly related to business use, such as preparing a vehicle for client transport.
Licence and registration fees. Provincial licence plate renewal fees and any registration costs are eligible.
Parking. Business-related parking fees are deductible. Monthly parking at your regular office does not qualify because the CRA treats your commute as personal driving.
Lease payments. If you lease your vehicle, monthly payments are deductible up to the 2026 cap of $1,100 per month before GST/HST. When your lease exceeds the cap, only $1,100 enters the calculation before the business-use percentage is applied. For a deep dive on the lease-versus-buy decision, see our guide on automobile deduction limits 2026 Canada.
Interest on a vehicle loan. If you financed the purchase, the interest portion of your payments is deductible up to $350 per month in 2026. Principal repayments are not deductible because the vehicle itself is handled through CCA.
Capital cost allowance (CCA). Depreciation on vehicles you own is claimed through CCA rather than as a direct expense. The CRA assigns vehicles to specific classes with their own rates and dollar caps. See the dedicated section below for details, or read our full guide on capital cost allowance vehicle Canada.
CCA Classes, Rates, and 2026 Dollar Caps
When you own a vehicle outright or finance it through a loan, the CRA does not let you deduct the purchase price in one year. Instead, you claim CCA over time using a declining-balance method.
Class 10 covers most trucks, vans, and commercial vehicles used primarily for business. The CCA rate is 30 percent on a declining balance with no dollar cap on the vehicle cost.
Class 10.1 applies to passenger vehicles where the cost exceeds the prescribed limit. For 2026, that limit is $39,000 before tax. Even if you paid $55,000, your CCA is calculated on the $39,000 ceiling. The rate is still 30 percent declining balance.
Class 54 covers zero-emission passenger vehicles and offers an enhanced first-year CCA rate. The 2026 capital cost limit is $61,000 before tax.
In the first year, the half-year rule applies: you claim CCA on only 50 percent of the eligible cost. For a Class 10.1 vehicle in year one, that means $39,000 times 30 percent times 50 percent equals $5,850 of maximum CCA before applying your business-use percentage.
Only the business-use portion of CCA is deductible. If your business-use percentage is 70 percent, your year-one CCA deduction becomes $5,850 times 70 percent, which is $4,095.
Who Can Claim: Self-Employed vs. Employees
Your employment status determines which form you file and what conditions you must meet.
Self-employed individuals report vehicle expenses in Part 4 of Form T2125 (Statement of Business or Professional Activities). No employer declaration is needed. You can choose between the actual-expense method and the simplified per-kilometre rate. Most self-employed taxpayers with annual vehicle costs above $5,000 benefit from the actual-expense approach. For a walkthrough of the T2125 form, see our guide on T2125 vehicle expenses self-employed.
Employees claim motor vehicle expenses on Form T777 (Statement of Employment Expenses). A critical requirement is that your employer must sign a T2200 (Declaration of Conditions of Employment) confirming that you are required to pay your own vehicle expenses and are not fully reimbursed. Without a signed T2200, the CRA will deny the entire claim.
Commission salespeople follow the same T777 process but may also deduct additional items such as meals and entertainment that salaried employees cannot. The T2200 must specify that the employee earns commission income and is required to cover expenses.
Regardless of your status, both methods require a detailed mileage log recording the date, destination, purpose, and kilometres of every business trip.
Expenses the CRA Will Not Allow
Not every vehicle cost is eligible. Knowing what the CRA rejects helps you avoid filing errors and audit risk.
Your daily commute between home and your regular workplace is personal driving. It does not matter how far you travel or whether you take business calls during the drive.
Traffic tickets and parking fines are never deductible, even when you receive them during a business trip.
Vehicle costs incurred during vacation or personal travel cannot be claimed, regardless of whether you check email or take a client call along the way.
The principal portion of loan payments is not deductible because the vehicle’s cost is already captured through CCA.
Record-Keeping That Survives a CRA Audit
The CRA can request your records at any time within six years of filing. A missing or incomplete mileage log is one of the most common CRA audit triggers for small business. To protect your deduction, maintain:
- A mileage logbook recording the date, destination, business purpose, route distance, and odometer reading for every trip
- Receipts for fuel, insurance, repairs, lease or loan payments, and parking
- Your lease agreement or financing contract
- Vehicle registration and insurance documents
- Odometer readings at January 1 and December 31 of each tax year
The CRA accepts digital records, including exports from a mileage tracking app, provided they are complete and unaltered. Tripbook stores every trip with GPS coordinates, timestamps, and distance calculations, giving you a CRA-ready audit trail without manual data entry.
Maximize Your Vehicle Expenses CRA Deduction
Your business-use percentage is the single biggest lever on your vehicle deduction. At 70 percent business use with $18,000 in annual costs, every additional percentage point of business driving is worth $180 in deductions. Forgetting to log even a few trips per week can cost you hundreds of dollars over a tax year.
Tripbook captures every business kilometre automatically with GPS tracking, classifies trips, and exports a complete CRA-compliant summary when you need it. Stop leaving deductions on the table.
