Documenting the Use of a Vehicle [Canada Revenue Agency, CRA]

When a vehicle is used partially for business purposes and partially for other purposes, the expenses relating to its use must be apportioned. Only those expenses relating to the business travel or commercial activity are considered eligible for a business deduction and for input tax credits on GST/HST. The proration in such cases is done based on the distances driven. To support a deduction or claim, the person must know and be able to demonstrate the distance travelled for business purposes and commercial activities.
