CRA Vehicle Expenses: How to Claim Fuel on Your Canadian Taxes

If you are self-employed in Canada and use your vehicle for business, you can deduct a portion of your vehicle expenses — including fuel — on your tax return. The Canada Revenue Agency (CRA) has specific rules about what you can claim, how to calculate your deduction, and what records you must keep.

This guide covers everything Canadian self-employed workers, freelancers, and gig drivers need to know about claiming vehicle and fuel expenses.

Unlike the US, Canada Has No Standard Mileage Rate

In the United States, self-employed workers can use a flat per-mile rate (72.5 cents/mile in 2026) instead of tracking actual expenses. Canada does not offer this option. Canadian taxpayers must use the actual expense method — tracking every vehicle-related cost and applying their business-use percentage.

This makes record-keeping essential. There are no shortcuts.

What Vehicle Expenses Are Deductible?

The CRA allows you to deduct the business-use portion of the following expenses:

• Fuel (gas, diesel)
• Oil and other fluids
• Insurance
• License and registration fees
• Maintenance and repairs
• Tires
• Loan interest (on a vehicle loan, up to limits)
• Leasing costs (up to CRA limits)
• Capital Cost Allowance (CCA) — depreciation on a vehicle you own
• Parking (business-related only)

You report these on Form T2125 (Statement of Business or Professional Activities), which is part of your T1 personal tax return.

The Logbook Requirement

The CRA requires a vehicle logbook to determine your business-use percentage. This is not optional — without a logbook, your entire vehicle expense deduction can be denied.

What the Logbook Must Include

For each business trip, record:

• Date of the trip
• Destination
• Purpose of the trip
• Number of kilometres driven

You must also record your odometer reading at the start and end of each tax year to establish total kilometres driven.

Base Year vs Simplified Method

You must keep a full logbook for at least one complete year — this is your "base year." In subsequent years, you can use the simplified method: keep a logbook for just three consecutive months. If the business-use percentage from the sample period is within 10% of your base year percentage, you can use the base year percentage for the full year.

If your driving patterns change significantly (new job, new city, new clients), you must start a new base year.

Calculating Your Business-Use Percentage

The formula is straightforward:

Business-use % = Business kilometres ÷ Total kilometres × 100

Example: You drove 25,000 km total in the year. 15,000 km were for business.

15,000 ÷ 25,000 = 60% business use

You then apply this percentage to your total vehicle expenses. If your total expenses were $8,000:

$8,000 × 60% = $4,800 deduction

Capital Cost Allowance (CCA)

If you own your vehicle (rather than lease it), you can claim CCA — the CRA's version of depreciation. Passenger vehicles fall into Class 10 or Class 10.1:

• Class 10: Vehicles costing $37,000 or less (before tax). CCA rate: 30% declining balance.
• Class 10.1: Vehicles costing more than $37,000 (before tax). Same 30% rate, but the depreciable amount is capped at $37,000 plus applicable taxes.

In the first year you acquire the vehicle, the half-year rule applies — you can only claim CCA on half the cost. Zero-emission vehicles may qualify for enhanced first-year CCA rates (Class 54).

Leasing Costs

If you lease your vehicle, you can deduct the business-use portion of your lease payments. However, the CRA caps the deductible lease amount at $950 per month (plus applicable taxes). If your lease payment is $1,200/month, you can only deduct based on $950/month.

Loan Interest

Interest on a loan used to purchase a vehicle is deductible. The CRA caps the deductible interest at $300 per month. As with other vehicle expenses, you can only deduct the business-use portion.

Filing: Form T2125 Walkthrough

Vehicle expenses are reported in the "Motor Vehicle Expenses" section of Form T2125. Here is what you will fill in:

1. Total kilometres driven in the fiscal period
2. Business kilometres driven in the fiscal period
3. Business-use percentage (calculated from above)
4. Total vehicle expenses — itemized by category (fuel, insurance, repairs, etc.)
5. Net deduction — total expenses multiplied by business-use percentage

You do not need to submit your logbook or receipts with your return, but you must keep them for at least six years in case the CRA requests them during an audit.

Common CRA Audit Triggers

• Business-use percentage over 90% — The CRA is skeptical of claims that a vehicle is used almost exclusively for business, especially if it is your only car.
• No logbook on file — If audited without a logbook, the entire deduction can be disallowed.
• Round numbers — Claiming exactly $5,000 in gas or exactly 50% business use looks estimated, not tracked. Precise numbers from actual records are more credible.
• Inconsistent years — A sudden jump from 40% to 80% business use without a change in circumstances raises flags.

How to Track Fuel Expenses in Canada

Since Canada requires the actual expense method, Canadian self-employed workers must track every fill-up. The most efficient approach:

1. Photograph or scan each gas receipt immediately after filling up (thermal paper fades fast in Canadian winters)
2. Use a dedicated fuel tracker like FuelSnap to extract station, volume, price, and total automatically
3. Maintain a logbook (physical or digital) alongside your fuel records
4. Export fuel totals quarterly to cross-reference with your logbook

The Bottom Line

Claiming vehicle expenses on your Canadian taxes requires more documentation than the US system, but the deduction can be substantial. Keep a logbook from day one, track every fuel receipt, and retain all records for six years. When filing time comes, you will have everything you need for Form T2125.

FuelSnap is free to start and supports Canadian dollars natively — scan your receipts in seconds and export clean records whenever you need them.
