Self-Employed Vehicle Expenses in Canada: How the CRA Method Works (2026)

Short answer: Self-employed vehicle expenses in Canada do not work on a flat per-kilometre rate. You deduct your actual costs — fuel, insurance, repairs, licence, interest, capital cost allowance — multiplied by your business-use percentage, which is business kilometres divided by total kilometres driven in the year. The Canada Revenue Agency (CRA) requires a logbook to support that percentage. The well-known “reasonable per-kilometre rates” (72¢ for the first 5,000 km in 2025, 73¢ in 2026) are tax-free allowances paid to employees, not a sole proprietor’s own deduction.

This is the most misunderstood rule for freelancers and sole proprietors in Canada. This guide explains the CRA method in plain language, with a worked example, a records checklist, and an FAQ. If you are still getting your bearings on the return as a whole, self-employed taxes in Canada is the wider map; this page is one line on it.

Do self-employed Canadians deduct a per-kilometre rate for their vehicle?

No. This is the core distinction.

• Self-employed / sole proprietor (you): You deduct a share of your real, receipted costs, reported on Form T2125, Statement of Business or Professional Activities, at line 9281 (motor vehicle expenses). The share is your business-use percentage.
• Employee with a per-km allowance: An employer can pay an employee a tax-free allowance based on the CRA “reasonable per-kilometre rates” set under section 7306 of the Income Tax Regulations. That is a payroll concept for employees. It is not the method a self-employed person uses to compute their own deduction.

So if you have read “just claim 72 cents a kilometre,” that advice is describing the employee allowance and does not apply to your business return. The CRA sets out the actual-expense method for sole proprietors under Motor vehicle expenses — deductible expenses on canada.ca.

Part of the confusion is imported. Freelancers in the United States genuinely do get to pick between the standard mileage rate and actual expenses, and a lot of the advice that surfaces in search was written for them. Canada gives sole proprietors one road, not two.

How does the CRA actual-expense method work?

The formula the CRA uses is a simple ratio:

Deductible vehicle expense = Total eligible vehicle costs × (Business kilometres ÷ Total kilometres driven in the fiscal period)

You add up all your eligible running costs for the year, then keep only the business-use portion. Everything hinges on two numbers from your logbook: business km and total km.

Which vehicle costs can I include?

Cost type	Typically deductible (business portion)	Notes
Fuel and oil	Yes	Keep receipts
Insurance	Yes	Business portion only
Licence and registration	Yes
Maintenance and repairs	Yes
Leasing costs	Yes	Ceilings apply; verify on canada.ca
Interest on a vehicle loan	Yes	Monthly limit applies; verify on canada.ca
Capital cost allowance (CCA / depreciation)	Yes	For a vehicle you own; a passenger-vehicle cost ceiling applies
Parking for business trips	Yes	Deducted in full as a business expense, not pro-rated
Parking fines / traffic tickets	No	Never deductible

Note: Parking directly related to earning business income and supplementary business insurance are generally claimed separately and in full, not reduced by the business-use ratio. Confirm the current leasing, interest, and CCA ceilings on canada.ca, as the dollar limits are updated most years.

What does a worked example look like?

Assume a freelance photographer drove 20,000 km total in the year, of which 12,000 km were to earn business income. That is a 60% business-use ratio (12,000 ÷ 20,000).

Expense	Amount paid (year)
Fuel	$3,200
Insurance	$1,800
Repairs and maintenance	$1,100
Licence and registration	$120
Loan interest (within CRA limit)	$900
Total eligible costs	$7,120

Deduction = $7,120 × 60% = $4,272 claimed at line 9281 on the T2125.

Capital cost allowance on the vehicle (also at 60% business use, within the passenger-vehicle ceiling) would be calculated and claimed separately. Business-trip parking receipts are added on top in full.

What logbook does the CRA require?

A logbook is not optional — it is how you prove the business-use ratio. The CRA states that for each business trip you should record the date, destination, purpose, and number of kilometres, and record the odometer reading at the start and end of the fiscal period. The full rules are on canada.ca under Motor vehicle records.

Two logbook options the CRA accepts

1. Full-year logbook: Record every business trip for the entire fiscal year. Most reliable.
2. Base-year + three-month sample: Keep a full logbook for one complete “base” year, then in later years keep a representative three-month sample. You can use the sample to estimate the full-year business use, provided your usage stays within about 10% of the base-year result. This is the CRA’s paper-burden-reduction option and is described on canada.ca under “Motor vehicle records.”

Vehicle records checklist

• Odometer reading on the first and last day of the fiscal period
• Date of each business trip
• Destination and business purpose of each trip
• Kilometres for each business trip
• Running total of business km and total km for the year
• Receipts for fuel, insurance, repairs, licence, interest, leasing
• Records kept for six years from the end of the tax year they relate to

The same discipline applies to every other expense line on the T2125: a claim is only as good as the paper behind it. What the CRA expects from your receipts and expense records covers that side of the file.

Is commuting a business kilometre?

Generally, no. Driving between your home and a regular place of business is usually personal (commuting) kilometres. Trips to meet clients, pick up supplies, or travel between work locations typically count as business kilometres. If you run your business from a qualifying home office, the calculus can change — check the specifics on canada.ca or with an accountant.

What if I change vehicles or start driving for business mid-year?

Nothing about the ratio changes, but the bookkeeping gets one layer deeper: the calculation is per vehicle, not pooled across the driveway.

• Keep a separate record for each vehicle. Two cars used for business means two logbooks, two sets of running costs, and two business-use percentages. You cannot average them.
• Buying, selling, or trading mid-year: the CRA asks you to record the date of the change and the odometer reading when you buy, sell, or trade a vehicle, on top of the usual start-and-end-of-period readings. That is what lets you show a partial-year total-kilometre figure that actually adds up.
• Costs follow ownership. Only the insurance, fuel, repairs, and interest you paid while you owned and used the vehicle for business belong in that vehicle’s total.
• Starting business use part-way through the year: when a personal car becomes a business car, for capital cost allowance purposes that change in use generally means the vehicle enters your CCA calculation at its fair market value on the day the use changes, not at what you originally paid for it years ago. This one has real dollars attached — confirm the current treatment on canada.ca or with your accountant before you claim it.

The practical failure mode here is the mid-year gap: someone sells a car in June, buys another in July, and never writes down either odometer. At that point the total-kilometre denominator is a guess, and a guessed denominator is not a provable business-use percentage.

How can Keel help with the logbook?

The CRA wants a contemporaneous, trip-by-trip record — and that is exactly what a mileage log is for. Keel: Invoice Maker & Receipts (by Ilura Technology) lets you log business trips and photograph your fuel, insurance and repair receipts on your iPhone. Everything stays on the device: no account, no sign-in, no bank connection, no cloud. The App Store privacy label reads “Data Not Collected.” Receipts are read on-device by Apple Intelligence, and the underlying ledger is append-only and hash-chained, so an entry you made in March still reads the same way a year later.

Two honest notes so you use Keel correctly:

• There is no automatic import from a bank feed. Every trip and every receipt is entered by hand or captured with the camera. That is the deliberate trade-off for nothing leaving your phone.
• Keel is a record keeper, not a filing tool. It holds the raw evidence — kilometres, dates, purposes, receipt images, the invoices you sent. Applying the business-use ratio to your actual costs and putting the result on the T2125 remains your job, or your accountant’s.

At year end the Accountant Pack exports the year as a CSV plus a one-page summary PDF, so the whole file arrives with your accountant in one send instead of as a shoebox of photos.

Frequently asked questions

Can I claim mileage instead of actual expenses if I am self-employed in Canada? No. Unlike some other countries, Canada does not offer sole proprietors a simplified flat-rate-per-kilometre deduction. You must use actual expenses multiplied by your business-use percentage, supported by a logbook. (The exception you may have heard of — the per-km “reasonable allowance” — applies to employees, not to your own business deduction.)

What is the 2025/2026 per-kilometre rate then, and when does it matter to me? For 2025 the CRA reasonable allowance rate is 72¢ for the first 5,000 km and 66¢ after (73¢ / 67¢ for 2026, higher in the territories). It matters if you pay an employee a vehicle allowance, or if you receive one as an employee. It does not set your sole-proprietor deduction. Verify current rates on canada.ca.

Do I need receipts, or is the logbook enough? You need both. The logbook proves the business-use percentage; the receipts prove the dollar amount of your costs. The CRA can disallow expenses you cannot support with records. The common failure is a tidy logbook with no fuel or repair receipts behind it, which shrinks the claim to whatever you can actually document. A card statement shows an amount but not what was bought, so keep the itemized receipt too.

How long do I keep vehicle records? Generally six years from the end of the last tax year they relate to, per the CRA. That covers the logbook, the start-and-end odometer readings, fuel and repair receipts, insurance and licence documents, and any lease or loan paperwork. If you file a return late, the six years run from the date you actually filed it. Keep your base-year logbook for as long as you are relying on it to justify a three-month sample year.

Where does this go on my tax return? Motor vehicle expenses (excluding CCA) go on line 9281 of Form T2125. You work the figure out in Chart A – Motor Vehicle Expenses on the form, which asks for your business kilometres, your total kilometres, and each cost category. Capital cost allowance for the vehicle is calculated separately in the CCA area of the same form, and business-trip parking is claimed in full. See Motor vehicle expenses (not including CCA) on canada.ca.
