If you drive for business, or you’re thinking about using your vehicle for work, you might wonder how to reduce your tax bill. Terms like “automobile benefits online calculator” or “revenue Canada mileage rates” may appear in your searches, but how do these actually help you? And what is an “automobile write off”?
This guide explains how Canada Revenue Agency (CRA) rules let you claim car expenses, from tracking your mileage log to using an automobile allowance rate. We’ll also look at mistakes to avoid, how to handle lease costs, and the difference between business and personal driving.

Introduction: Why Car Write-Offs Matter
When you’re self-employed or have a side hustle, your vehicle can become an important tool for work. Maybe you drive to meet clients, deliver goods, or scout new work locations. Each trip can add up in gas, maintenance, and wear. The CRA recognizes this and lets you claim certain costs if the driving is genuinely for business. Doing so can lower your taxable income and potentially save you hundreds or thousands of dollars at tax time.
But writing off a car for business isn’t automatic; you have to follow specific guidelines. Questions like “how many kilometres did you drive purely for work?” or “did you buy your car or lease it?” affect how much you can claim. Also, automobile benefits online calculator tools can estimate your possible deduction, but it’s your logs and receipts that prove your claim to the CRA. So if you want a decent automobile write off, keep reading to see how to make the most of these allowances.
Key Terms and CRA Basics
Here’s a quick rundown of common phrases you’ll encounter:
- Car on Tax / Write-Off Car: This is everyday language for “claiming vehicle costs as business expenses.”
- Revenue Canada Mileage Rates / Canada CRA Mileage Rate: Each year, the CRA sets standard per-kilometre rates used if you’re reimbursing employees or yourself with an “automobile allowance.”
- CRA Motor Vehicle Expenses: The CRA’s category for deducting costs (fuel, insurance, repairs) based on the business use portion.
- Capital Cost Allowance (CCA): A system for depreciating long-term assets, like a vehicle, over time. If you own the car, you can only claim the portion that relates to business usage.
Essentially, your main goal is to separate business from personal driving and to track how many kilometres you use for each. This helps you figure out the fraction of your vehicle costs that are truly business-related.
CRA Vehicle Expenses: What Counts as Business Use
The CRA states you can only deduct costs that help you earn business income. That means personal errands don’t count. Driving to a friend’s place for coffee? That’s personal. Driving to buy supplies for your home office? That’s business. If your total annual distance is 10,000 km and 4,000 of those kilometres are for clients or business errands, you can claim 40% of your relevant costs. Keep logs showing date, destination, purpose, and mileage for each trip.
Examples of Business Usage
- Driving to a meeting with a potential client
- Picking up inventory from a supplier
- Traveling to a conference or tradeshow
- Making deliveries or site visits
Non-Business Trips
- Grocery shopping for personal needs
- Taking your family to the beach
- Daily commuting from home to a separate office (for employed individuals, that’s not typically a business expense)
If you hold a job as an employee, commute mileage is rarely deductible. But self-employed people can often claim driving from their home office to client sites.
Tracking Methods: Odometer Readings and the Revenue Canada Mileage Log
An official mileage log might feel cumbersome, but the CRA sees it as the best proof of how many kilometres you used for business vs. personal. Typically, a mileage log should include:
- Date: The day you took the trip
- Destination: Where you went
- Reason/Purpose: e.g., “client meeting” or “picking up office supplies”
- Number of Kilometres Driven: The difference between your start and end odometer readings
At year’s start, record your odometer reading as 0. By December 31, note the final reading. This helps confirm total distance driven for the entire tax year, from which you can apply the business portion. Tools exist, like phone apps, to automate logging.
If you skip a log, you might estimate, but it’s riskier. The CRA may question large claims if you don’t have solid documentation. Some people keep a “log sample” for a typical period and then do the same each year, but you must maintain consistency. The revenue canada mileage rates also help if you prefer a simpler allowance approach, but that’s typically for employee use or when paying yourself a standard rate.
Commonly Deductible Vehicle Costs
Below is a short list to consider. Not every expense might apply to you, and some might overlap with personal usage if your car is partly personal. In that case, you only claim the business fraction.
- Fuel & Oil: Gasoline, diesel, or alternative fuelling, plus regular oil changes.
- Insurance: Car coverage. If it’s mostly for personal, claim only the part used for business.
- Maintenance & Repairs: Routine check-ups, new tires, brake fixes.
- License & Registration: Plate fees, province-specific licensing costs.
- Tolls & Parking: E.g., if you pay toll roads or parking for a meeting with clients.
- Lease Costs: If you lease, the portion for business is deductible, subject to certain maximums.
- Interest on Auto Loan: If you own the vehicle with financed credit, the interest portion for business usage is typically deductible.
(If you buy a car, you might do capital cost allowance (CCA) instead of a direct cost claim on the vehicle’s purchase price. Maintenance, though, remains an immediate expense each year.)
Lease vs. Purchase: Handling Payments and Depreciation
When deciding whether to lease or buy, consider both your cash flow and your future plans for the car.
Lease
- Monthly Payment: You can usually claim a portion, up to CRA limits. If the lease is expensive, you might face a deduction cap.
- No Depreciation: Since you don’t own the car, you don’t do capital cost allowance.
- Fewer Upfront Costs: Often cheaper monthly out-of-pocket if you want a new vehicle.
Purchase
- Capital Cost: The car is an asset. You claim a fraction each year via the auto write off method known as capital cost allowance.
- CCA Classes: A standard passenger vehicle might be Class 10 or 10.1, with different depreciation rules.
- Long-Term: If you keep the vehicle for many years, you build up CCA until you dispose of it.
In some cases, if you buy an emission passenger vehicle or zero-emission car, you may qualify for accelerated write-off. The rules can change, so check for updated incentives.
Automobile Allowance Rates and Other Approaches
If you pay yourself (or employees) a per-kilometre rate, you might rely on the official “automobile allowance rates” the CRA issues annually. For example, if the Canada cra mileage rate is 68 cents for the first 5,000 km (just an example figure), each business km you drive can be reimbursed at that rate. As a business, you’d deduct that sum as a cost. If you’re self-employed, it might be simpler to stick with actual expenses. For employees, a “reasonable allowance” is often tax-free.
Methods
- Actual Expenses: Tally actual fuel, repairs, insurance, etc., multiplied by your business usage ratio.
- Per-Kilometre Allowance: The official revenue canada mileage rates, if you pay or reimburse a driver. Usually simpler, but may not reflect your exact cost if you drive a fancy or older vehicle.
Frequently Asked Questions
1. How do I know if I can claim car expenses for business?
You need to use the vehicle to earn business income. If your car is partly personal, only the fraction of usage that’s business qualifies. Keep a log to show the ratio of business vs. personal driving.
2. What is the best way to write off a car if I’m self-employed in Canada
Either record actual expenses and apply the business-use percentage or use an automobile allowance approach if you prefer paying yourself a per-km rate. Both can be valid; choose whichever yields the fair deduction while meeting CRA guidelines.
3. Can I claim 100% of my car costs if I use it sometimes for personal reasons?
No. If you blend usage, you must track the portion of the year that’s truly for business. Only that fraction of costs is deductible.
4. How do I claim a new car’s cost?
Generally, you use capital cost allowance (CCA). Each year, you write off a percentage of the undepreciated balance. This applies if you purchase the vehicle. For lease, you claim a portion of lease payments.
5. What if I’m an employed individual but also do freelance gigs on the side?
Your day-job commute isn’t deductible. But if you drive to freelance clients after hours, you can track that mileage and claim those expenses under your side business. Keep separate logs to prove the difference.
Conclusion and Next Steps
Writing off a car for business is one of the more attractive tax breaks for Canadian entrepreneurs and side-hustlers, but it demands good recordkeeping. You can’t guess how much you drove; the CRA expects either a mileage log or consistent method to prove your “car on tax” claims. Once you figure out your ratio of business to personal driving, you can deduct that proportion of fuel, insurance, repairs, lease or depreciation, and even things like parking or tolls.
Final Pointers
- Choose a Method: Actual costs or standard mileage (if paying an allowance).
- Keep a Log: The difference between a smooth deduction and a potential CRA query is strong evidence.
- Separate: Don’t mix personal errands with business runs. If you do, keep a precise record so you only claim the business portion.
- Stay Up to Date: “revenue Canada mileage rates” can change each year. If you reimburse employees or yourself, use the current data from CRA to avoid paying too much or too little.
By applying these tips, your business taxes get simpler, and you pay only what you owe—while still benefiting from the legitimate expenses of running a vehicle. If it’s your first time, test out an automobile benefits online calculator for an estimate, then refine with real receipts and mileage logs. The result: potential lower tax and better clarity on how each kilometre helps drive your business forward.
