Please note the best method for vehicle expenses is using the regulated Canada Revenue Agency method. This method requires the total kilometers driven in the fiscal year and the total kilometers used to earn business income in the fiscal year.
When a vehicle is driven for both business and personal use, a trip log must be used to record the kilometers. Only the business portion of the vehicle expenses can be deducted from the income.
The log should record the date of each business trip, destination, reason for the trip, and the kilometers driven. The odometer reading of the vehicle must also be recorded, at the beginning and end of each year, to determine the total kilometers driven in the fiscal period.
If you buy or trade your vehicle during the year, be sure to record the odometer reading at that time.
