Vehicle Expense Deduction for Business in Canada
Learn how the vehicle expense deduction works for Canadian sole proprietors: logbooks, business-use percentage, CRA records, and T2125 reporting.
A vehicle expense deduction lets a Canadian sole proprietor deduct the business-use share of a vehicle's operating costs — fuel, insurance, maintenance and similar items — on their personal income tax return. Because a sole proprietorship is not a separate taxpayer, you report these amounts on Form T2125, Statement of Business or Professional Activities, and file it with your T1 return for the current tax year.
Who Can Claim Motor Vehicle Expenses
You can generally claim the motor vehicle expenses CRA allows when you use a vehicle to earn business income. The costs must be reasonable, must relate to earning income, and you must be able to support them with records. A few common boundaries:
- Driving between two business locations, or from a home office to see a client, is usually business driving.
- Commuting between home and a regular place of business is generally personal driving, even if you also work from home — see Home Office Expense Deduction in Canada.
- Only the business portion of a mixed-use vehicle is deductible.
Which Vehicle Costs Are Deductible
Typical deductible items, each limited to your business-use percentage, include:
- Fuel, oil and fluids
- Insurance, licence and registration fees
- Maintenance, repairs and tires
- Business parking and tolls
- Interest on a loan used to buy the vehicle
- Leasing costs, subject to CRA limits
- Capital cost allowance on a purchased vehicle
Traffic fines and parking tickets are never deductible, and neither is the personal portion of any expense.
| Expense | Generally deductible? | Notes |
|---|---|---|
| Fuel, repairs, insurance | Business portion | Apply your business-use percentage |
| Parking tickets and fines | No | Not incurred to earn income |
| Vehicle purchase price | Through CCA | Passenger vehicles face a cost ceiling — confirm the current amount on canada.ca |
| Lease payments | Business portion | The deduction may be limited for higher-cost passenger vehicles |
Calculating Your Business-Use Percentage
Your business mileage deduction depends on how much you drive for business. Keep a logbook that records the date, destination, purpose and kilometres of each trip, plus your total kilometres for the year. The percentage is:
Business kilometres ÷ total kilometres × 100
Multiply each expense by that percentage. If, for example, 40% of your annual kilometres were for business, you could claim 40% of your fuel and insurance costs. The CRA also describes a simplified logbook approach, where a full 12-month logbook in a base year is followed by a three-month sample in later years if certain conditions are met; confirm the current requirements on canada.ca before relying on it.
Buying a Vehicle: Capital Cost Allowance
If you buy a vehicle, you normally cannot deduct the full purchase price at once. Instead you claim capital cost allowance (CCA), a yearly deduction based on the vehicle's cost. Passenger vehicles are subject to a maximum cost ceiling set by the CRA, and different ceilings may apply to certain zero-emission vehicles — confirm the current amounts before calculating your claim. See Capital Cost Allowance (CCA) in Canada Explained.
GST/HST and Input Tax Credits
If you are registered for GST/HST and use the vehicle for business, you can generally claim input tax credits for the GST/HST paid on the business portion of your vehicle expenses. Special limits apply to passenger vehicles, so the credit may be less than the full tax paid. Review Input Tax Credits (ITCs) in Canada Explained, and if you are not yet registered, check whether your revenue keeps you under small supplier status.
Records You Should Keep
Keep receipts, invoices, insurance documents, loan or lease agreements, and your logbook. The CRA generally expects records to be kept for six years from the end of the last tax year to which they relate; confirm the current retention rule on canada.ca. If your records are incomplete, the CRA may reduce or disallow part of your claim. A logbook maintained as you drive is far stronger evidence than one reconstructed months later.
Reporting Vehicle Expenses on Your Return
Report your gross business income and expenses on Form T2125. The motor vehicle expense area captures both your total vehicle costs and the business-use portion, and that business-use figure flows through to the business income lines of your T1 return alongside your other deductions — see Sole Proprietorship Tax Deductions in Canada. If you also work from home, a vehicle claim and an office claim can both be supportable when each is properly calculated.

Frequently asked questions
How much of my vehicle expenses can I claim for my business?
You claim the business-use percentage of each eligible expense, not a flat rate. Divide your business kilometres by total kilometres for the year, then apply that percentage to fuel, insurance, repairs and similar costs. If half your driving was for business, roughly half of those costs are deductible. Keep a logbook and receipts so the percentage is documented and defensible.
Do I need a logbook to claim motor vehicle expenses?
A logbook is the standard way to prove your business-use percentage, and the CRA can ask to see it during a review. Record the date, destination, purpose and kilometres for each trip, plus your annual total kilometres. The CRA also describes a simplified logbook method using a three-month sample after a full base year; confirm the current conditions on canada.ca.
Can I claim vehicle expenses if I use my car for both personal and business driving?
Yes, but only the business portion. Split your costs using your business-use percentage and deduct that share. Personal driving, including commuting between home and a regular place of business, is not deductible even if you also maintain a home office. Driving between client sites, suppliers or a home office and a client can generally qualify.
Can I deduct the purchase price of a vehicle for my sole proprietorship?
Not all at once. A purchased vehicle is normally a capital asset, so you claim capital cost allowance over time rather than deducting the full price in the year of purchase. Passenger vehicles are subject to a maximum cost ceiling set by the CRA, and confirm the current amounts on canada.ca before calculating your claim.
