Motor vehicle expenses
Since you can deduct motor vehicle expenses only when they are reasonable and you have receipts to support them, keep a record for each vehicle you used. The record should include the total kilometres you drove as well as the kilometres you drove to earn employment income. The record for each trip you took to earn employment income should list the date, destination, purpose, and number of kilometres. Record the odometer reading of each vehicle at the beginning and again at the end of the year.
If you change motor vehicles during the year, record the odometer reading of each vehicle at the time you buy, sell, or trade it. Write down the dates as well.
If you and somebody else own or lease the same passenger vehicle, the limits on CCA, interest, and leasing costs still apply, and in case of zero-emission passenger vehicles, the limits on CCA and interest will apply. The total amount the joint owners can claim cannot be more than the amount that would be allowed if only one person had owned or leased the vehicle.
Employment use of a motor vehicle
If you use a motor vehicle for both employment and personal use, you can deduct only the percentage of expenses related to earning income. To support the amount you can deduct, keep a record of both the total kilometres you drove and the kilometres you drove to earn employment income. The CRA considers driving back and forth between home and work as personal use.
If you use more than one motor vehicle to earn employment income, calculate the expenses for each vehicle separately.
For more information about motor vehicle expenses, see Type of vehicle you own.
