If you are self-employed in Canada and use a vehicle for work, a mileage log is only part of the story. Receipts provide supporting context for vehicle costs such as fuel, maintenance, parking, insurance, repairs, and supplies. Neither a receipt nor a mileage log alone proves tax treatment.
The goal is not to create a complicated binder. It is to build a simple habit that makes each driving-related expense easier to understand later, especially when you are preparing tax records or answering an accountant’s questions.
This guide focuses on what to capture, what notes to add, and how vehicle receipts and mileage records can work together without turning your phone, glove box, and inbox into separate filing systems.
Start with the difference between mileage and receipts
Mileage records describe business driving, while receipts describe costs connected to owning, operating, parking, maintaining, or using the vehicle. The CRA’s motor-vehicle record guidance calls for total and business kilometres, the date, destination, purpose, and kilometres for each business trip, opening and closing odometer readings for the fiscal period, and separate records for each vehicle. When more than one vehicle is used for business, keep a separate record for each vehicle showing the total and business kilometres and the cost to run and maintain it, and calculate each vehicle’s expenses separately.
Those two records are stronger together because they answer different questions:
- A mileage log explains the business use pattern.
- A receipt documents a cost for later review.
- A note connects the cost to the business context.
- An export gives your accountant a clean review file instead of scattered images.
If your mileage routine needs work first, read PKTD’s CRA mileage deduction guide for a plain-language overview of mileage tracking habits. Then use this article to tighten the receipt side.
Vehicle receipts worth keeping in one place
A good vehicle receipt system captures more than fuel. Depending on your business and vehicle use, you may want to keep organized records for common vehicle-related costs such as:
- Fuel and charging receipts
- Oil changes, repairs, inspections, and maintenance
- Tires, wipers, fluids, and other vehicle supplies
- Parking and toll receipts
- Car washes connected to client-facing or work use
- Insurance, registration, lease, loan, or ownership documents
- Roadside assistance or vehicle service records
- Rental vehicle, rideshare, courier, or delivery-related support receipts when relevant
This is not a promise that every item is deductible for every person. The useful habit is to keep the receipt, add enough context, and let the current CRA rules or a qualified professional determine treatment.
Add business purpose before you forget it
Vehicle receipts often look generic when you review them later. A gas station receipt rarely explains whether you were on the way to a client, picking up supplies, driving between job sites, or making a personal trip.
Add a short note as soon as you scan or save the receipt. Useful notes include:
- The client, project, job site, market, delivery route, or appointment connected to the expense
- Whether the stop happened during a business trip or a mixed personal/business day
- The vehicle the receipt belongs to if your household uses more than one
- Any missing detail from the printed receipt, such as a faded merchant name or unclear total
- Whether the cost should be reviewed with an accountant before filing
The note does not need to be long. A clear sentence is usually better than a vague category. For example: “Parking near client meeting downtown” is more helpful than “parking.”
Keep vehicle categories simple
Too many categories make receipt tracking harder to maintain. Too few categories make the year-end review slower. A balanced setup usually separates vehicle records into a handful of practical buckets:
Fuel or charging
Use this for receipts tied to operating the vehicle. If you drive an electric vehicle for work, keep charging records as consistently as fuel receipts. Add notes when the printed or emailed receipt does not clearly identify the location or payment details.
Maintenance and repairs
Put oil changes, repairs, inspections, tires, parts, and service invoices together. These receipts often contain useful dates and odometer readings, so scan the full document instead of only the payment slip.
Parking and tolls
Parking and toll records are easy to lose because they are small, fast, and often digital. Capture paper slips, app receipts, emailed confirmations, and screenshots in the same system so they do not stay trapped in separate places.
Insurance, registration, and ownership records
Some vehicle documents are not everyday receipts, but they still matter for your records. Keep renewals, policy documents, registration confirmations, lease statements, or financing records where they can be found during review.
Review or ask accountant
Use a temporary review category when you are unsure. It is better to flag a receipt than to guess. During your monthly or quarterly review, move it to the right category or ask a professional how to treat it.
Match receipts to your mileage routine
Vehicle expense records are easiest to review when receipts and mileage are not maintained in separate worlds. You do not need to attach every receipt to a specific trip, but you should be able to explain the business-use pattern behind your vehicle costs.
A simple routine looks like this:
- Log each business trip’s date, destination, purpose, and kilometres as close to the drive as possible.
- Scan or save related vehicle receipts the same day.
- Add a short note when the business purpose is not obvious.
- Review the week for missing parking, toll, fuel, or service receipts.
- Record the fiscal period’s opening and closing odometer readings and export summaries before accountant handoff. When more than one vehicle is used for business, keep a separate record for each vehicle showing the total and business kilometres and the cost to run and maintain it, and calculate each vehicle’s expenses separately.
If you are catching up, work backward by week instead of trying to reconstruct the entire year at once. Calendar entries, client appointments, delivery records, bank transactions, and email receipts can help you spot missing context.
Do not rely on the glove box
The glove box is useful for temporary storage, not long-term bookkeeping. Paper receipts fade, curl, tear, and get separated from the trip that made them meaningful. Vehicle receipts are especially vulnerable because many are printed on thermal paper.
A better workflow is:
- Scan the receipt before it fades.
- Confirm the merchant, date, tax, and total are readable.
- Add a category and business-purpose note.
- Keep records for the required period. Canadian business records are generally kept for six years, with exceptions that can require longer retention.
- Destroy paper only under a CRA/CGSB-compliant imaging program with the required controls and reproducibility; otherwise, retain the original.
- Export organized records before tax time instead of searching the car in a rush.
For details, review the CRA’s guidance on retention periods and electronic records and imaging paper. For emailed receipts and app-based parking records, avoid leaving them in your inbox. Save or scan them into the same receipt system you use for paper slips so your records are searchable in one place.
Watch for mixed-use situations
Many self-employed Canadians use the same vehicle for business and personal life. That makes clear recordkeeping more important. A receipt alone may show the cost, but it does not show how the vehicle was used overall.
For mixed-use situations, focus on documentation instead of guesswork:
- Keep a consistent business mileage log.
- Keep all relevant vehicle receipts in readable form.
- Add notes for costs that are clearly tied to specific work activity.
- Separate personal-only receipts when they should not be part of business records.
- Review current CRA guidance or ask a qualified professional before claiming anything uncertain.
This is the same principle behind other mixed-use expenses: explain the business context while the memory is fresh. PKTD’s guide to mixed-use expense receipts in Canada covers that broader documentation habit.
Prepare cleaner records for your accountant
A useful vehicle expense handoff is not a shoebox, camera roll, or folder of mystery PDFs. Aim to give your accountant a package that is easy to review:
- Receipt images that are legible
- A CSV or PDF summary with dates, merchants, categories, taxes, and totals
- Mileage logs or summaries kept alongside receipt records
- Notes explaining unusual repairs, large purchases, or client-specific travel
- A review list of items you are unsure about
You do not need perfect wording. You need consistent context. The cleaner your records are before tax season, the less time you spend answering avoidable questions.

Bottom line
Vehicle expense receipts are easiest to manage when you capture them during the week, add business context while you still remember it, and review them alongside your mileage records. Keep the system simple: readable receipt, useful category, short note, regular review, clean export.
That habit gives you better records for tax time without forcing you to become a full-time bookkeeper.
