Yes, you can deduct vehicle maintenance and repair costs if you use your vehicle for business purposes. If this CRA rule applies to you, eligible expenses include oil changes, tire replacements, brake repairs, windshield replacements, and routine servicing. These costs are only deductible for the business-use percentage of your vehicle. For example, if you use your vehicle 60% for business and 40% for personal driving, you can only claim 60% of your maintenance expenses. The Canada Revenue Agency allows you to deduct "reasonable costs" for keeping your vehicle in working condition. This includes: Oil changes and fluid top-ups Tire purchases and repairs Brake pad and rotor replacement Battery replacement Windshield and window repairs Suspension and steering repairs Engine and transmission work Rust protection and undercoating (if applied to a used vehicle) Car wash and detailing (if used primarily for business) Safety inspections and emissions testing These are considered "repair" expenses because they restore your vehicle to working condition without substantially improving its value or extending its useful life beyond its original condition. Not all vehicle-related spending qualifies.
No. You can only deduct the business-use percentage of repair costs. If you use your vehicle 70% for business and 30% for personal driving, you can claim 70% of maintenance expenses. Keep a mileage log to support this calculation.
A complete engine replacement is typically a capital improvement because it substantially extends the vehicle's useful life beyond its original condition. You cannot deduct it as a repair. Instead, the cost must be capitalized and claimed over time through depreciation.
Car insurance premiums and vehicle registration are separate vehicle expenses and have their own deduction rules. They are generally deductible for business vehicles, but maintenance costs are tracked separately on your tax return.
The CRA expects you to maintain accurate records showing business-use percentage. If you cannot document this clearly, the CRA may disallow your claim entirely. Start tracking mileage now and keep all receipts separated by business and personal use.
Car washing is generally not deductible as it is considered a personal grooming expense for the vehicle. However, if the vehicle is a mobile billboard for your business or you operate a fleet where appearance is critical to your business reputation, this rule may differ. Consult a tax professional about your specific situation.
