How to Claim Vehicle Expenses for Business Use in Canada

Your car might be doing more for your business than you realize.

Maybe you drive across town to meet clients. Perhaps you're constantly picking up supplies, delivering orders, or travelling between job sites.

And somewhere between filling the tank and paying for another oil change, you've probably wondered:

Can I claim any of this on my taxes?

In Canada, the answer is often yes. But there's a catch.

Using your vehicle for business doesn't automatically make every kilometre or every vehicle expense deductible.

The Canada Revenue Agency (CRA) generally expects you to separate business driving from personal driving, keep supporting records, and calculate your claim using the appropriate rules.

Fortunately, you don't need to be an accountant to understand the basics.

Let's work through what counts, what doesn't, and how to calculate a claim without relying on guesswork.

Can You Claim Vehicle Expenses for Business Use in Canada?

If you're self-employed and use a vehicle to earn business income, you may be able to deduct reasonable vehicle expenses related to that business use.

This can apply to freelancers, consultants, tradespeople, delivery businesses, and other self-employed individuals.

For example, you might use your vehicle to:

• Visit clients or customers

• Travel between business locations

• Pick up business supplies

• Deliver products

• Transport equipment to a job site

• Make other trips directly connected to earning business income

But what if you use the same vehicle for grocery shopping, family outings, and weekend road trips?

You generally can't claim the full cost of running it.

Instead, you'll need to calculate how much of the vehicle's use was genuinely business-related.

This article focuses primarily on self-employed business owners. Employees claiming employment-related vehicle expenses, and corporations paying for or reimbursing vehicle use, can face different rules.

Business Kilometres vs. Personal Kilometres: Where's the Line?

This is one of the most important distinctions in the entire process.

The CRA doesn't simply ask whether you're a business owner.

It asks whether the travel was connected to earning business income.

Trips That May Count as Business Driving

Examples include:

• Driving from your business premises to a customer's location

• Travelling between separate job sites

• Going to a supplier to purchase business inventory

• Delivering goods to customers

• Driving to a meeting directly related to your business

The trip must have a legitimate business purpose, and you need sufficient records to support it.

Trips That Are Usually Personal

Examples include:

• Grocery shopping

• Family visits

• Holidays and recreational trips

• Personal appointments

• Ordinary travel between home and a regular workplace

That last example deserves special attention.

Does Driving From Home to Work Count?

Not automatically.

Ordinary commuting between home and a regular workplace is generally personal travel.

However, the situation may be different when your home is genuinely your principal place of business and you're travelling from there to customer locations or other business destinations.

The classification depends on the actual circumstances, not simply whether you sometimes work from home.

Similarly, driving to a client location where you routinely work may require closer consideration than an occasional visit to a customer.

When in doubt, document the purpose of the trip and confirm that it qualifies before counting it as business mileage.

Which Vehicle Expenses Can You Deduct?

Once you've identified your eligible business driving, you can consider the expenses associated with operating the vehicle.

The CRA identifies several types of potentially deductible motor vehicle costs.

Not every expense is treated the same way.

For instance, routine operating expenses and the purchase price of a vehicle follow different tax rules.

And if you have an expensive passenger vehicle, you may encounter limits that affect how much you can claim.

What About Parking?

Parking fees directly connected to business activities can generally be deducted separately from the normal business-use percentage calculation.

For example, if you pay $12 to park while attending a client meeting, that expense may be fully deductible if the trip and parking are genuinely business-related.

Parking for a personal shopping trip does not become deductible just because you own a business.

What About Traffic Tickets?

Don't include fines or penalties for breaking the law as ordinary deductible vehicle expenses.

A parking ticket isn't the same thing as a legitimate business parking fee.

How to Calculate Your Business Vehicle Expenses

Here's the formula that makes the process easier to understand.

Business-use percentage = Business kilometres ÷ Total kilometres driven × 100

Then:

Deductible operating expenses = Business-use percentage × Eligible shared vehicle operating expenses

Certain costs, such as qualifying business parking fees and supplementary business insurance, may be added separately.

Let's look at a realistic example.

Meet Daniel, a Self-Employed Photographer

Daniel uses his car for client meetings, photography sessions, and picking up equipment.

He also uses the same vehicle for everyday personal driving.

Throughout 2025, he kept records of his trips.

At the end of the year, his mileage log showed:

His business-use percentage is:

4,800 ÷ 12,000 × 100 = 40%

So, 40% of his vehicle's total use was for business.

Step 1: Add Up His Operating Expenses

Daniel's vehicle expenses for the year were:

For simplicity, assume these amounts were reasonable, properly supported, and eligible to be allocated based on vehicle use.

This example doesn't include financing interest, leasing costs, capital cost allowance, or GST/HST input tax credits.

Step 2: Apply His Business-Use Percentage

Daniel's business use was 40%.

Therefore:

$4,500 × 40% = $1,800

His deductible share of the shared operating expenses is $1,800.

Step 3: Add Eligible Business-Specific Costs

During the year, Daniel also paid:

These costs are treated separately because they relate directly to business activity.

Step 4: Calculate the Total Claim

Daniel's example produces a $2,000 vehicle-expense deduction.

It does not mean the CRA sends him a $2,000 cheque.

A tax deduction generally reduces the income on which tax is calculated. The actual tax savings depend on his financial and tax circumstances.

And remember: Daniel's claim is supported by his mileage records and receipts, not simply his estimate that he probably drove for business about 40% of the time.

What Is a Mileage Log, and Why Does the CRA Want One?

A mileage log is a record of the trips you make using your vehicle.

It helps distinguish eligible business travel from personal driving.

The CRA considers an accurate logbook maintained throughout the year to be strong evidence supporting vehicle-related deductions.

For each business trip, record:

• Date

• Destination

• Business purpose

• Kilometres travelled

You should also record the vehicle's odometer reading at the beginning and end of the relevant fiscal period.

If you replace the vehicle during the year, record the date and odometer reading associated with the change.

What Does a Mileage Log Look Like?

Here's a simple example.

This is only a sample of a few business trips, not a complete annual log.

For a full-year claim, keep consistent records of business travel and the vehicle's total kilometres.

Can You Use an App Instead of a Paper Logbook?

Yes, electronic mileage records can be useful if they accurately capture the required information and remain accessible.

An app may help record trip distances, dates, and destinations while reducing manual work.

But don't assume a trip is deductible simply because an app labelled it “business.”

You still need to confirm the purpose and classification of the journey.

Can You Use the CRA's Simplified Mileage Logbook?

Possibly, but there's a condition many people miss.

The CRA allows an eligible simplified approach after you've established a full base year of vehicle-use records.

Generally, the process involves:

1. Maintaining a complete logbook for a full 12-month base year.

2. Recording a representative three-month sample in a later year.

3. Comparing the sample results with the corresponding period in the base year.

4. Applying the CRA's calculation and consistency requirements.

The calculated annual business-use percentage must remain within the CRA's permitted range relative to the base year, and the base year must still represent your normal vehicle use.

You cannot simply record three months of driving when you've never established a qualifying base year and assume that automatically meets the simplified method's requirements.

For most people starting out, maintaining a complete log is the clearest approach.

Should You Claim a Flat Amount for Every Business Kilometre?

This is where confusion often starts.

You may have heard about the CRA's automobile allowance rates.

For 2026, the federal government announced rates of 73 cents per kilometre for the first 5,000 kilometres and 67 cents per additional kilometre in the provinces, with higher rates in the territories.

But those figures relate to the tax treatment of certain employer-paid automobile allowances.

They are not a universal flat-rate income-tax deduction that every self-employed business owner can multiply by their kilometres.

If you're self-employed and claiming the costs of using your own vehicle, the usual approach is to calculate the allowable business portion of eligible actual expenses.

Don't substitute employer allowance rates for the actual-expense calculation simply because the per-kilometre formula looks easier.

What If You Bought or Leased the Vehicle?

Owning or leasing a vehicle can introduce additional rules.

If You Bought the Vehicle

The full purchase price of a vehicle used as a capital asset generally isn't deducted as an ordinary operating expense in the year you buy it.

Instead, you may be eligible to claim capital cost allowance, commonly called CCA.

CCA generally allows the cost of a qualifying depreciable asset to be deducted over time, subject to the rules for its class and business use.

The relevant amount depends on the vehicle's classification, acquisition date, cost, and other factors.

If You Leased the Vehicle

Eligible lease costs may be deductible, but passenger vehicle leasing expenses are subject to limits and calculations.

For new leases entered into on or after January 1, 2026, the announced maximum deductible leasing cost remained $1,100 per month before tax, subject to additional rules.

This is not an automatic $1,100 deduction for every leased vehicle or every month of personal use.

What About Vehicle Loans?

Interest on money borrowed to purchase a vehicle used to earn business income may be deductible, subject to applicable restrictions.

However, loan principal repayments aren't treated the same way as deductible interest expenses.

For new passenger vehicle loans entered into on or after January 1, 2026, the announced maximum allowable interest deduction remained $350 per month, subject to the relevant calculation and business-use restrictions.

Do Expensive Vehicles Have Special Limits?

Yes.

For Class 10.1 passenger vehicles acquired on or after January 1, 2026, the federal government announced a CCA capital cost ceiling of $39,000 before tax.

The corresponding ceiling for qualifying vehicles acquired in 2025 was $38,000 before tax.

Special limits also apply to certain zero-emission passenger vehicles.

Which rules apply depends on when the vehicle was acquired and how it is classified for tax purposes.

For this reason, purchasing an expensive car through a business doesn't automatically make its entire cost deductible.

Where Do You Claim Vehicle Expenses on Your Canadian Tax Return?

For many sole proprietors, motor vehicle expenses are reported through Form T2125 — Statement of Business or Professional Activities.

The form is used to report self-employment business or professional income and expenses.

Relevant entries include:

• Line 9281: Motor vehicle expenses, excluding CCA

• Line 9936: Capital cost allowance

• Chart A: Calculation of motor vehicle expenses

Partnerships and certain other business activities may have different reporting requirements.

Incorporated businesses must follow the rules applicable to their corporate expenses, ownership arrangements, and any personal-use benefits or reimbursements.

If you're an employee rather than a self-employed business owner, separate employment-expense requirements may apply.

How Long Should You Keep Vehicle Expense Records?

Mileage logs, fuel receipts, insurance documents, repair invoices, and other supporting records are part of your business recordkeeping obligations.

The CRA's general retention rule is six years from the end of the last tax year to which the records relate, with exceptions that can extend the period.

A base-year mileage log used in the simplified logbook method may need to be retained longer because its information continues to support subsequent years.

Vehicle purchase and disposal records can also remain relevant well beyond the year of acquisition.

For a detailed explanation of the retention rules, see How Long Do You Need to Keep Business Receipts in Canada?

The important thing is to retain records for as long as they remain relevant to your tax obligations.

Common Vehicle Expense Mistakes That Are Easy to Avoid

Even if your calculations are straightforward, small recordkeeping mistakes can cause problems.

Guessing Your Business-Use Percentage

“I use my car for business quite a lot” isn't the same as a supported percentage.

Keep a mileage log and calculate the actual business-use share.

Counting Ordinary Commuting as Business Travel

Driving from home to your regular workplace generally doesn't become business travel merely because you own the business.

Consider the nature of the trip and any applicable exceptions.

Forgetting About Personal Driving

If your vehicle serves both business and personal purposes, your total kilometres should reflect both.

Leaving personal trips out of the total can artificially increase your business-use percentage.

Mixing Up Vehicle Payments and Expenses

Fuel, insurance, loan interest, loan principal, leasing costs, and the purchase of a vehicle don't all receive the same tax treatment.

Categorize them correctly.

Throwing Away Supporting Receipts

A mileage log helps establish how much you drove for business.

It doesn't replace the receipts needed to support the amounts you spent operating the vehicle.

Combining Records for Multiple Vehicles

If your business uses more than one vehicle, maintain separate records and calculations for each one.

This is especially important when the vehicles have different business-use percentages or tax classifications.

Make Every Business Kilometre Count

Your vehicle might be one of the hardest-working tools in your business.

But when tax season arrives, the CRA needs more than a rough estimate of how often you drove it.

The strongest starting point is a reliable system: record your business trips, keep receipts, calculate your business-use percentage, and apply that percentage to the appropriate expenses.

If you own, lease, or finance a passenger vehicle, pay attention to the additional tax limits.

Most importantly, don't leave the mileage log until the end of the year.

Your future self will be grateful when you're not trying to remember why you drove across town on a rainy Tuesday eight months ago.
