How to Claim Vehicle Expenses on Your Tax Return

If you use your personal vehicle for business purposes in Canada, you can deduct the business-use portion of your vehicle expenses. But CRA has specific rules about what qualifies, how to calculate it, and what records you need to keep. Make sure to include vehicle expenses on your deduction checklist. Here's the complete guide.

Who Can Claim Vehicle Expenses?

• Self-employed individuals who use their vehicle for business (claimed on T2125) — see our full list of T2125 deductions
• Employees required to use their personal vehicle for work, with a signed T2200 from their employer (claimed on T777)
• Commission employees with a T2200 (claimed on T777)

Important: Driving from home to your regular workplace is not a business expense — that's commuting. Business driving includes travel to client sites, meetings at other locations, errands for business supplies, and travel between work locations as part of your self-employed tax reporting.

The Mileage Log: Non-Negotiable

CRA expects you to maintain a vehicle logbook that records:

• Date of each business trip
• Destination and purpose
• Kilometres driven (business vs. personal)
• Odometer reading at the start and end of the year

Without a log, CRA can deny your entire vehicle claim on audit. There's no shortcut here — keep the log.

Pro tip: After you've kept a full 12-month logbook, CRA may accept a three-month sample logbook in subsequent years, as long as it's representative. But you need at least one full-year base period first.

What Expenses Are Deductible?

You can claim the business-use percentage of these expenses:

Operating Expenses

• Fuel and oil
• Insurance
• Licence and registration fees
• Maintenance and repairs
• Tires
• Car washes (yes, really)
• Parking (business-related — not your daily commute)
• Supplementary business insurance

Ownership Expenses

• If you own the vehicle: Capital Cost Allowance (CCA) — this is depreciation. For most passenger vehicles, the CCA rate is 30% (Class 10) on a declining balance. If your vehicle is a zero-emission vehicle (ZEV), you may qualify for the enhanced Class 54 rate.
• If you lease: Lease payments (subject to CRA's monthly lease cost ceiling — $1,050/month for 2025, before tax)
• Interest on a car loan: Deductible up to CRA's limit ($350/month for 2025)

How to Calculate the Deduction

Step 1: Track Total and Business Kilometres

At year-end, calculate your business-use percentage:

Business-use % = Business km ÷ Total km driven

Example: You drove 25,000 km total, and 15,000 km were for business → 15,000 ÷ 25,000 = 60%

Step 2: Add Up All Vehicle Expenses

• Fuel: $3,600
• Insurance: $1,800
• Maintenance: $1,200
• Registration: $120
• Lease payments: $7,200 (within CRA ceiling)

Total: $13,920

Step 3: Apply Business-Use Percentage

$13,920 × 60% = $8,352 deduction

CRA Limits on Vehicle Costs (2025)

CRA caps certain vehicle costs to prevent luxury vehicle abuse:

• CCA ceiling (Class 10.1): $37,000 + tax for passenger vehicles (if the vehicle cost exceeds this, you claim CCA on $37,000 only)
• Lease payment ceiling: $1,050/month + tax
• Loan interest ceiling: $350/month
• Tax-exempt per-km allowance: $0.72 for the first 5,000 km, $0.66 thereafter (this is what employers can pay tax-free — if you receive an allowance at these rates, you can't also claim expenses)

Own vs. Lease: Tax Considerations

Leasing is often simpler for tax purposes — you deduct the lease payments directly (subject to the ceiling). No CCA calculations, no tracking undepreciated capital cost.

Owning can be more advantageous if the vehicle cost is under the CCA ceiling and you plan to keep it for many years. The CCA deduction continues as long as you own the vehicle and use it for business.

What If You Receive a Vehicle Allowance?

If your employer pays you a vehicle allowance:

• Reasonable allowance (based on km driven, at or below CRA rates): Tax-free, but you cannot also claim vehicle expenses
• Flat-rate allowance (not based on km): It's added to your T4 income, and you can claim your actual expenses

If your employer's per-km rate is below CRA's reasonable rates and doesn't cover your costs, you may be able to include the allowance in income and claim actual expenses instead. Consult the rules carefully or ask a tax professional.

Common Mistakes to Avoid

• ❌ Claiming commuting mileage as business use
• ❌ Not keeping a mileage log
• ❌ Claiming 100% business use on a vehicle that's also used personally
• ❌ Exceeding CRA's cost ceilings without adjusting
• ❌ Forgetting to prorate if you bought/sold the vehicle mid-year

The Bottom Line

Vehicle expenses can be one of the largest deductions for self-employed Canadians, but CRA scrutinizes them closely. The key is simple: keep a log, keep your receipts, and calculate honestly. The deduction is there for you — just claim it properly. Use our tax savings calculator to estimate your vehicle deduction.
