If you use a motor vehicle for business and personal use, you can deduct only the part of the expenses that you paid to earn income.
Example
Danielle owns a hardware store that has a December 31 year-end. She has a van that she uses for the business.
Danielle noted the following for the tax year:
Kilometres driven to earn business income: 27,000
Total kilometres driven: 30,000
Expenses:
Licence and registration fees = $ 100
Gas and oil = $ 2,400
Insurance = $ 1,900
Interest = $ 800
Maintenance and repairs = $ 200
Total expenses for the van = $ 5,400
Danielle calculates the expenses she can deduct for her van for the tax year as follows:
(27,000 business kilometres ÷ 30,000 total kilometres) x $5,400 = $4,860
The deductible business part of Danielle's van expenses is $4,860.
She can claim this amount on line 9281 of Form T2125, Statement of Business or Professional Activities.
