Vehicle Expense Tracking for Self-Employed Canadians: The Complete CRA Guide

Vehicle expenses are one of the largest deductions available to self-employed Canadians, but they are also one of the most frequently audited. The CRA has specific rules about what qualifies, how to track your driving, and how much you can claim. Get it right and you save thousands. Get it wrong and you face reassessment.

This guide covers everything you need to know about claiming motor vehicle expenses on your T2125 as a sole proprietor, freelancer, or independent contractor.

Business Use vs Personal Use

The CRA does not let you deduct 100% of your vehicle costs unless you use the vehicle 100% for business, which is rare for sole proprietors who also drive for personal reasons. Instead, you calculate a business-use percentage and apply it to your total vehicle expenses.

The formula:

Business kilometres / Total kilometres = Business-use percentage

What counts as business use:

• Driving to meet clients or customers
• Trips to suppliers or to pick up materials
• Travel between business locations
• Driving to the bank or post office for business errands
• Travel to conferences, trade shows, or business events

What does not count:

• Driving from home to your regular place of business (commuting)
• Personal errands, even if done during the workday
• Vacations, even if you do some work while travelling

The home office exception: If your home is your principal place of business (as declared on your T2125), driving from home to a client's location counts as business use, not commuting. This is a significant advantage for freelancers who work from home.

The CRA Logbook Requirement

The CRA requires you to keep a logbook to support your vehicle expense claim. This is not optional. Without a logbook, the CRA can deny your entire vehicle expense deduction upon audit.

What the Logbook Must Include

For each business trip, record:

• Date of the trip
• Destination (name and address)
• Purpose of the trip (client meeting, supply pickup, etc.)
• Kilometres driven for the trip

At the beginning and end of the tax year, record your odometer reading. The difference gives you total kilometres for the year. Your logbook entries give you business kilometres. The ratio is your business-use percentage.

The Base Year and Sample Year Method

The CRA allows a simplified approach after your first full year of record-keeping:

1. Base year: Keep a complete, detailed logbook for one full 12-month period.
2. Sample years: In subsequent years, keep a logbook for a representative three-month period. If the three-month sample is within 10% of the same three months in your base year, you can use your base-year percentage for the full year.
3. New base year required: If your business-use pattern changes by more than 10%, you need to establish a new base year with a full 12-month logbook.

This method reduces the ongoing record-keeping burden, but you must maintain that first full-year logbook meticulously.

What Vehicle Expenses Qualify

Here is a complete list of motor vehicle costs you can deduct, subject to your business-use percentage:

Operating Expenses

Expense	Notes
Fuel (gas, diesel, electricity)	Keep fuel receipts or credit card statements
Oil and fluids	Routine top-ups and changes
Insurance	Annual premium for the vehicle
Licence and registration	Annual provincial fees
Repairs and maintenance	Mechanical repairs, tire replacement, oil changes
Car washes	If used for client-facing business
Parking	Business parking only; not parking at your home or regular office
Supplementary insurance	Roadside assistance, extended warranty on a leased vehicle
Tires	Winter and summer tires

Financing Costs (Choose One)

You have two options depending on how you acquired the vehicle:

Option A — You own the vehicle: Claim Capital Cost Allowance (CCA) on the vehicle. The purchase price goes into CCA Class 10 or 10.1, and you claim depreciation each year. You also deduct the interest on your car loan, subject to limits.

Option B — You lease the vehicle: Claim your lease payments as an expense, subject to the CRA's prescribed monthly limit. You cannot also claim CCA, since you do not own the vehicle.

You cannot claim both CCA and lease payments.

Class 10 vs Class 10.1: Which Applies to Your Vehicle?

The CRA separates vehicles into two CCA classes based on cost:

Class 10 (30% declining balance)

Your vehicle goes in Class 10 if:

• It is a motor vehicle (trucks, vans used primarily for business), OR
• It is a passenger vehicle that costs at or below the CRA's prescribed limit

For 2024, the prescribed cost limit for a passenger vehicle was $37,000 (before sales tax). The CRA updates this limit periodically, so check the current year's figure.

Class 10 vehicles are pooled together. All your Class 10 vehicles share one undepreciated capital cost (UCC) balance.

Class 10.1 (30% declining balance)

Your vehicle goes in Class 10.1 if:

• It is a passenger vehicle that costs more than the prescribed limit

Each Class 10.1 vehicle gets its own separate class. This has three important consequences:

1. No terminal loss. When you sell or trade in a Class 10.1 vehicle, you cannot claim the remaining UCC as a terminal loss.
2. No recapture. The CRA will not add back previously claimed CCA as income when you dispose of the vehicle.
3. Capped cost base. Your CCA is calculated on the prescribed limit, not the actual purchase price. If you bought a $55,000 vehicle and the limit is $37,000, your CCA is based on $37,000.

Passenger Vehicle Limits

The CRA caps several vehicle-related costs for passenger vehicles. These limits apply regardless of CCA class:

Limit Type	2024 Amount
CCA cost ceiling (Class 10.1)	$37,000 + sales tax
Monthly lease payment cap	$1,050 + sales tax
Deductible loan interest cap	$300/month
Tax-exempt per-km allowance rate (first 5,000 km)	$0.70/km
Tax-exempt per-km allowance rate (additional km)	$0.64/km

These limits are updated by the CRA annually. Always check the current year's prescribed amounts before filing.

How to Calculate Your Vehicle Deduction

Here is the step-by-step calculation:

Step 1: Total Your Vehicle Expenses

Add up all operating costs: fuel, insurance, registration, repairs, maintenance, parking, and either lease payments or CCA plus loan interest.

Step 2: Apply Your Business-Use Percentage

Multiply the total by your logbook-derived business-use percentage.

Step 3: Respect the Caps

If your vehicle is a passenger vehicle, ensure your lease payments, interest, and CCA base do not exceed the prescribed limits.

Worked Example

Maria is a freelance photographer. She drove 25,000 km total in 2025, with 15,000 km for business (60% business use). She owns her vehicle outright (original cost $30,000, Class 10).

Expense	Annual Amount
Gas	$3,600
Insurance	$1,800
Licence and registration	$200
Repairs and maintenance	$1,400
Car washes	$120
Parking (business only)	$280
CCA (30% of opening UCC $18,000)	$5,400
Total vehicle costs	$12,800

Maria's deduction: $12,800 x 60% = $7,680

She reports this on line 9281 (motor vehicle expenses) of her T2125.

Tips for Surviving a CRA Audit

Motor vehicle expenses are a top audit target. Protect yourself:

• Start your logbook on January 1. A logbook that starts in March looks like an afterthought.
• Be consistent. Record every business trip, not just the ones you remember at tax time.
• Keep all receipts. Fuel receipts, repair invoices, insurance statements, and registration documents.
• Be honest about personal use. Claiming 90% business use on a family sedan raises red flags. The CRA knows what realistic percentages look like for different occupations.
• Record odometer readings. Note the odometer at January 1 and December 31 every year.
• Photograph your odometer. A timestamped photo on your phone is easy evidence.

Digital Logbook Options

The CRA accepts digital logbooks as long as they contain the required information and are contemporaneous (recorded at or near the time of the trip, not reconstructed months later).

A mobile app that uses GPS to track trips and automatically calculates distances is ideal. The key is to log the purpose of each trip and ensure the records are exportable and backed up.
