As the rules for writing-off business use of auto expenses are complicated and very inflexible, CRA auditors will always examine them. So follow the rules closely if you want your deduction to pass a tax audit.
To write-off your self-employed business vehicle expenses in Canada when you use your personal vehicle, the vehicle must be used for earning business income. Personal use expenses are not deductible. A mileage logbook is required as well as supporting documents and receipts.
There are three distinct areas of CRA rules pertaining to vehicles:
(1) tax deductions for self-employed individuals,
(2) allowances and reimbursements for employee supplied automobiles , and
(3) employer supplied automobiles - the company car.
This article will discuss the first area; self-employed individuals and their vehicles which was touched upon when we discussed employee auto allowances. Page 8 of Form T2125 Statement of Business or Professional Activities is devoted solely to motor vehicle expenses for the self-employed.
Soooo ... you use your personal vehicle for business and are wondering how and what to write-off for your business tax deduction.
If it is tax time and you are just sitting down to figure how to claim the use of your personal vehicle in your business ... you may be out of luck for this year. You need to do some advance tax planning in order to claim this deduction.
Here's a quick overview on how it works.
As stated, only the business portion of vehicle usage is tax deductible. The personal portion is not deductible. This means your business vehicle expenses are prorated based on kilometers driven. This presents a problem for you as a small business owner. How do you prove to the tax auditor how often your vehicle was used for business purposes?
The easy answer is a mileage logbook ... the hard answer is a mileage logbook! Remember I said writing-off this deduction required advanced planning. The auto logbook is easy to talk about but requires discipline to maintain. Take the time to develop the habit if you want to audit-proof your vehicle expense claims. Without it, the tax auditor can reduce or deny your claim.
Do not confuse these two CRA published rates as a viable option for writing-off your business vehicle expenses:
The image below shows how business vehicle expenses are claimed on Chart A on your tax return. It is found on page 8 of Form T2125 Statement of Business or Professional Activities.
Things to observe:
Looking at Chart A above, notice that you can claim all your operating expenses such as:
Capital cost allowance (CCA) is calculated and claimed in Area A on page 5. It is important to note that CCA is an optional deduction allowing you to choose when to claim the deduction to receive maximum benefit. Use it only if your other expenses were not enough to reduce your business income to zero.
If you are driving your personal vehicle for business purposes, make sure you are insured for business driving. It is not enough to just have personal pleasure coverage or drive to work (like an employee) coverage.
You are making this deduction because you say it is a business expense. ... so don't skimp here. Keep all your ducks in a row and your story line congruent with your main premise ... that you are incurring this expense with the expectation of earning profit sooooo ... all your supporting documentation must support this premise.
You can deduct the full amount of the business vehicle supplemental insurance on line 15.
What happens if you get in an accident while driving your car for business and you aren't insured for business use of your car?
If you get into an accident while using your personal vehicle for business purposes, and you're not insured for business use, it might create some complications, particularly when it comes to claiming from your insurance provider. Personal auto insurance policies typically do not cover accidents that occur during business-related activities.
If your insurance company determines you were using your vehicle for business purposes when the accident occurred, they may deny your claim based on the exclusion for business-use of the vehicle. This could leave you responsible for all costs associated with the accident, including repair costs and any potential liability for damage to other vehicles or property, or injuries to others.
In the worst-case scenario, if you're found to have misrepresented the use of your car to your insurer (i.e., stating it's for personal use when in fact it's for business use), the insurance company could potentially cancel your policy.
It's always recommended to discuss with your insurance agent or provider about your car usage to ensure you have the necessary coverage, whether it is for personal or business use or both.
Variable expenses are the expenses you incur by driving the vehicle; using the vehicle creates "wear and tear" expenses on the vehicle. For example, fuel, tires, repairs and maintenance are variable operating costs.
Fixed expenses are the expenses you incur that are not "caused" by driving the vehicle but as a result of owning the vehicle. They are all the costs you still have to pay even if you don't drive the vehicle. For example, depreciation, auto insurance, license and registration, financing charges, leasing payments are fixed costs.
Fixed expenses usually have associated legal paperwork you need to retain for record keeping purposes.
Chart B below calculates deductible interest expense; and Chart C calculates your eligible leasing costs for the passenger vehicle category.
Chart B and Chart C calculations are carried up into Chart A on lines 4 and 8 respectively.
If you have purchased your vehicle, you are eligible to claim the expense over time through use of CCA (capital cost allowance). The amount your deduction is affected by the type of vehicle you have and which CCA category your vehicle fits into. The purpose of the limits is to prevent business owners writing off luxury vehicles as required for business purposes.
The types of vehicles and their 2024 capital cost restrictions are:
*Use class 10 if the cost of the vehicle is less than the threshold. Terminal losses and recapture rules are not available for class 10.1 vehicles.
** if purchased after March 18, 2019. Prior to this it was classed as 10 or 10.1. A new class 56 was introduced March 1, 2020 for ZE automotive equipment that is not designed for use on highways or streets.
ACCELERATED CCA FOR ZEVs
In 2019, the government introduced accelerated CCA rates for ZEVs. They expanded the write-off in 2020 for other ZEVs.
Accelerated ZEV Rates for eligible vehicles:
Be aware there are strict acquistion, disposal, and personal use rules (including possible taxable benefits for employees who use a company vehicle) and restrictions for vehicles ... and auditors love to audit this deduction just to make sure you have followed those rules.
If you purchased your vehicle, you are eligible to claim an interest deduction up to a limit set by CRA. In 2024, the daily interest limit is $10 per day.
Example: Your interest cost is $700 a month. The rules restrict your interest expense claim to $10 a day. If you used your passenger vehicle 65% for business (usage supported by your mileage log), you can only deduct $10 x 65% = $6.50 a day. The 35% personal use component is not tax deductible.
You can see how to calculate your deductible interest expense in Chart B below. Historical daily interest limits are shown below.
Jan 1, 2001 to present -- $10.00
Jan 1, 1997 to Dec 31, 2000 -- $8.33
Sep 1, 1989 to Dec 31, 1996 -- $10.00
Jun 17, 1987 to Aug 31, 1989 -- $8.33

A long term leased passenger vehicle is not entitled to claim CCA (capital cost allowance). However, you are allowed to claim a percentage of your lease payment to a limit of $1,050 before taxes in 2024. Personal use is not deductible.
Example: Your lease cost is $1,200 a month before GST, HST, or GST + PST. The rules restrict your claim to $1,050. If you used your passenger vehicle 65% for business (usage supported by your mileage log), you can only deduct $1,050 x 65% = $682.50 before tax. The 35% personal use component is not tax deductible.
This limit is reduced again based on the list price of the vehicle; referred to as a capital cost ceiling. The purpose of this second restriction is to prevent businesses writing off luxury cars as a business expense.
Reference: CRA's publication IT-521R Motor Vehicle Expenses Claimed by Self-Employed Individuals; also T4002 Self-Employed Business, Professional ... has a nice chart to help you classify your vehicle so you know which rules to follow.
Your eligible leasing cost claim is calculated in Chart C shown above. Historical monthly lease limits are listed below.
These limits apply not only to self-employed individuals but also employees who use their personal vehicles for business purposes.
