Claiming automobile deductions on your Canadian tax return can reduce your taxable income significantly — but the rules are detailed, and CRA scrutinises vehicle claims closely. Whether you are self-employed or an employee who uses your own car for work, understanding the logbook requirement, the 2025 luxury limits, and the correct CCA class for your vehicle will ensure you claim every dollar you are entitled to while staying onside with CRA.
Two categories of taxpayers can deduct vehicle expenses in Canada, and the forms they use are different.
Self-employed individuals report business income on Form T2125 (Statement of Business or Professional Activities). Vehicle expenses used to earn business income are deductible as a business expense on that form, subject to the business-use percentage determined by your logbook.
Employees can only deduct vehicle expenses if their employer requires them to use their personal vehicle for work, does not fully reimburse them, and issues a signed Form T2200 (Declaration of Conditions of Employment). Qualifying employees claim their vehicle costs on Form T777 (Statement of Employment Expenses). Commissioned employees and certain salaried employees who meet the T2200 conditions are both eligible, but the specific eligible expenses differ slightly between the two groups.
In both cases, commuting from your home to your regular place of work is not deductible. CRA treats that as a personal trip regardless of how far you live from the office.
A logbook is the foundation of any vehicle deduction claim. CRA requires you to record the following for every business trip:
You also need to record your total odometer readings at the start and end of the calendar year so CRA can verify your total kilometres driven. The ratio of business kilometres to total kilometres driven during the year becomes your business-use percentage, and that percentage is applied to every eligible vehicle expense you want to deduct.
CRA requires you to keep your logbook — along with all receipts — for a minimum of six years from the end of the tax year to which they relate.
If your driving patterns are consistent from year to year, CRA allows a practical shortcut. You keep a complete logbook for one full base year, establishing your business-use percentage for that period. In subsequent years, you keep a simplified logbook that records only your business kilometres (not every personal trip). At year-end you compare the simplified logbook results to the base year. If business use remains within 10 percentage points of the base year, you can use the base year percentage for that subsequent year. If your driving patterns have changed materially, you need to run a full logbook again for that year.
This approach is a legitimate time-saver for business owners whose client visits, routes, and overall driving habits are stable — something the team at Swift Accounting Calgary regularly helps clients set up correctly from the start.
Once you have your business-use percentage, you apply it to the following eligible expenses:
The following are not deductible: traffic fines and penalties, the personal portion of any expense, and driving from home to your regular place of employment.
Loan interest limit for 2025: If you financed the vehicle, only the interest attributable to the business portion is deductible, and CRA caps the total interest you can claim at $300 per month for 2025 ($10 per day). If your monthly interest is lower than $300, you use the actual amount.
Capital cost allowance is how you deduct the depreciation of your vehicle over time. The class your vehicle falls into depends on what it cost and whether it is a zero-emission vehicle (ZEV).
Passenger vehicles and light trucks that cost $38,000 or less (before GST/HST and PST) fall into Class 10. The CCA rate is 30% on a declining balance, meaning you deduct 30% of the undepreciated capital cost (UCC) each year. In the year of acquisition, the half-year rule applies, so you can only claim 15% in year one.
If your passenger vehicle cost more than $38,000, it goes into Class 10.1. The rate is still 30% declining balance, but the maximum cost you can use for CCA purposes is capped at $38,000. That means even if you paid $70,000 for your vehicle, CCA is calculated as if the vehicle cost only $38,000. Each Class 10.1 vehicle must be kept in its own separate CCA class — you cannot pool multiple luxury vehicles together.
There is one taxpayer-friendly rule unique to Class 10.1: in the year you dispose of the vehicle, you are entitled to claim a half-year of CCA (unlike Class 10, where you get nothing in the year of disposal under the normal rules).
Zero-emission passenger vehicles — battery electric, plug-in hybrid electric, and hydrogen fuel cell vehicles — have a higher luxury threshold of $61,000 for 2025. ZEVs costing $61,000 or less generally qualify for accelerated CCA. ZEVs costing more than $61,000 fall into Class 10.1 with the CCA cost capped at $61,000. Class 55 applies to ZEV taxis and rideshare vehicles and carries an accelerated CCA rate.
The luxury limit affects both CCA and lease deductions. Consider this example: you purchase a non-ZEV sedan for $70,000. Because the cost exceeds $38,000, the vehicle is Class 10.1 and CCA is calculated on a deemed cost of $38,000 only. In year one (with the half-year rule and assuming 70% business use), your CCA claim would be: $38,000 × 15% × 70% = $3,990 — even though the actual vehicle depreciated on a much higher base.
Lease deductions are similarly restricted (details in the leased vehicles section below). These limits are designed to prevent taxpayers from fully subsidising luxury personal vehicles through business deductions.
CRA publishes prescribed rates each year that employers use when reimbursing employees for business driving. For 2025, the rates are:
These rates are primarily relevant for employers paying allowances to employees. If an employer pays a reasonable per-kilometre allowance at or below these prescribed rates, the allowance is not taxable to the employee and the employee cannot also claim vehicle expenses. Self-employed individuals cannot use the per-kilometre method in place of actual expenses — they must track real costs with a logbook and receipts.
If you lease rather than own your vehicle, the monthly lease payment is deductible for the business-use portion, but CRA limits how much of the monthly payment you can use in the calculation.
For 2025, the monthly lease deduction limit is:
Your deduction is the lesser of your actual monthly lease payment or the applicable limit, multiplied by your business-use percentage. There is also a formula that applies when the value of the vehicle exceeds the luxury threshold, to prevent an inflated lease payment on a high-value vehicle from circumventing the luxury cap.
For example, if you lease a non-ZEV vehicle and your monthly payment is $900, you use $900 (the actual payment, since it is below $1,050). If your business-use percentage is 65%, your monthly deductible amount is $585. If your monthly lease payment is $1,300, you are capped at $1,050 before applying the business-use percentage.
If you need help modelling the lease-versus-buy decision from a tax perspective, Swift Accounting Calgary can work through the numbers with you before you sign.
Automobile deductions involve more moving parts than most business expenses — logbooks, CCA class selection, the luxury limits, and the interaction between business-use percentage and every individual expense category. Getting any one of these wrong can mean leaving money on the table or attracting a CRA review. Our team can review your situation, help you set up a compliant logbook system, and ensure your T2125 or T777 reflects the full deduction you have earned.

Yes — there is no minimum threshold of business kilometres. Even occasional business driving is deductible, provided you have a logbook documenting every business trip. Your business-use percentage will simply be lower, so the deductible portion of your expenses will be proportionally smaller. CRA does scrutinise very low business-use claims, so accurate records are essential.
Without a logbook, CRA can deny your entire vehicle expense claim on audit. Reconstructing a logbook after the fact using calendar entries, Google Maps history, or client invoices may partially support your claim, but CRA is not obligated to accept reconstructed records. Going forward, even a simple notes app on your phone recording date, destination, purpose, and kilometres satisfies the requirement if you are consistent.
No. The $38,000 threshold (and the $61,000 ZEV threshold) is based on the cost of the vehicle before GST/HST and provincial sales tax. GST/HST and PST are added to your actual vehicle cost for accounting purposes, but the CCA limit itself is applied to the pre-tax purchase price when determining which class the vehicle falls into and what cost base is used for CCA calculations.
Yes — these are separate deductions and one does not affect the other. If you are self-employed and use part of your home as your principal place of business or as a space where you exclusively and regularly meet clients, you may be eligible to claim home office expenses on your T2125 in addition to vehicle expenses. Similarly, employees who meet the T2200 conditions for home office use and vehicle use can claim both on Form T777, subject to the applicable rules for each.
