When a vehicle is used for both personal and business purposes, it is necessary to keep a log to record the business use of the vehicle. Please see our article on keeping a vehicle log found here:

Unincorporated Business

An unincorporated business may write off (deduct) all reasonable motor vehicle expenses which are on account of the business use of the vehicle. If your trip log indicates that your use of the vehicle was 30% personal, and 70% business then you will be able to deduct 70% of the vehicles expenses.

Incorporated Business

An incorporated business may also write off all reasonable motor vehicle expenses.

If the business provides a company vehicle to a shareholder, or employee for personal purposes, a taxable benefit will be added to their income. Contact Barrett Tax Law Today.

Expenses Allowed

Motor vehicle expenses include interest on loans to purchase automobiles, capital cost allowance, automobile leasing costs, and operating expenses such as fuel, oil, maintenance and repairs, license and insurance costs, and car washes.

Parking costs are not included as motor vehicle expenses. When the parking is related to business use of the motor vehicle it is 100% deductible, and when it is related to personal use it is not deductible.
