As a chartered professional accountant, I understand the importance of maximizing tax deductions for small business owners. One of the most significant expenses for a small business is the cost of operating a vehicle, whether it is for business use or personal use.

As per the Canadian Revenue Agency (CRA), business-related vehicle expenses can be claimed as deductions on your tax return if they meet certain conditions. This blog post will provide an overview of the rules and regulations surrounding vehicle expenses for sole proprietors and partnerships in Canada.

Expense Eligibility

Vehicle expenses are eligible for tax deductions if they are incurred for the purpose of earning business income. This includes expenses such as fuel, maintenance, insurance, and vehicle registration fees. However, the CRA requires that you keep accurate records of your vehicle usage to support your claim.

Method of Calculation

There are two methods to calculate your vehicle expenses: the standard mileage rate or actual expenses.

Standard Mileage Rate

The standard mileage rate is a set amount per kilometer driven for business purposes. The current rate, set by the CRA, is $0.58 per kilometer for the first 5,000 kilometers driven and $0.52 per kilometer for each additional kilometer. This method is straightforward and requires only a logbook to track your business km driven.

Actual Expenses

The actual expense method requires you to track all vehicle-related expenses and apportion them between personal and business use. This method is more complicated, but it may result in a higher deduction if your actual expenses are higher than the standard mileage rate.

Keep in mind that the CRA may disallow some expenses, such as luxury upgrades or personal insurance costs, if they are not directly related to earning business income.

Record Keeping

Regardless of which method you choose, it is essential to keep accurate and detailed records of your vehicle expenses. The CRA may request documentation to support your claim, so it is crucial to have proper documentation of all expenses, including:

Vehicle purchase or lease agreement

Receipts for fuel, maintenance, insurance, and other expenses

A logbook to track the business km driven (if using the standard mileage rate)

A summary of the expenses, including the calculation of the business portion (if using the actual expenses method)


Vehicle expenses can be a significant expense for sole proprietors and partnerships in Canada, but they also provide an opportunity to maximize tax deductions. It is important to understand the rules and regulations surrounding vehicle expenses, and to keep accurate records to support your claim.

If you have any questions or need assistance with your vehicle expenses, don't hesitate to contact a chartered professional accountant. They can help ensure that you are claiming the maximum deduction allowed by law, and that your records meet the standards set by the CRA.
