A vehicle expense report records what a car, van, or motorcycle actually costs to run — mileage driven, fuel, servicing, insurance, and repairs — either to claim reimbursement from an employer or client, to support a tax deduction, or simply to know what your own vehicle is costing you. The free templates below cover both personal and commercial use. For general business expenses — travel, meals, accommodation, supplies — see our expense report templates instead.
What a Vehicle Expense Report Covers
Three kinds of record, often kept together:
- Mileage log — every business journey with its date, purpose, start and end odometer readings, and miles driven. This is the record that reimbursement and tax claims are actually built on, and the one most people reconstruct badly from memory months later.
- Running costs — fuel, servicing, repairs, tyres, insurance, road tax, parking, tolls, and cleaning. Kept with dates, amounts, and receipts.
- The claim or summary — the report you submit: total business miles at the applicable rate, or the business share of actual costs, with receipts attached.
What a Mileage Log Looks Like
The core record. Keep it in the vehicle, or fill it in the same day — a log written contemporaneously is far more defensible than one assembled at year end:
| Date | From ? To | Purpose | Start | End | Miles | Type |
|---|---|---|---|---|---|---|
| 02 Sep | Office ? Meridian Ltd | Client meeting | 54,210 | 54,242 | 32 | Business |
| 04 Sep | Office ? Depot ? Office | Stock collection | 54,242 | 54,289 | 47 | Business |
| 05 Sep | Home ? Supermarket | Personal | 54,289 | 54,301 | 12 | Personal |
| 09 Sep | Office ? Site B ? Office | Installation visit | 54,301 | 54,385 | 84 | Business |
| Business miles this period | 163 | |||||
| Claim at [your rate] per mile | 163 × rate | |||||
Two details make a log worth keeping: the purpose column, because “client meeting — Meridian Ltd” is evidence and “business trip” isn’t, and logging personal journeys too, so the odometer readings run continuously. A log with gaps invites the question of what happened in them.

Two Ways to Claim: Mileage Rate or Actual Costs
Whether you’re claiming from an employer or against tax, there are broadly two methods, and you generally can’t mix them for the same vehicle in the same period:
1. A rate per mile (or kilometre). You multiply business miles by a set rate that’s intended to cover fuel, wear, servicing, insurance, and depreciation together. Simple, and it only requires a mileage log. Most employers reimburse this way, and many tax authorities publish an approved rate — check the current figure for your country, since rates are revised periodically and often differ for cars, vans, and motorcycles.
2. Actual costs, apportioned. You total everything the vehicle costs over the year — fuel, insurance, servicing, repairs, tyres, road tax, and often depreciation or finance costs — then claim the business proportion, based on business miles as a share of total miles. More paperwork, and it needs receipts for everything, but it can be worth more for expensive vehicles, high running costs, or low-efficiency engines.
Either way you still need the mileage log: method one to count the miles, method two to work out the business percentage. Rules on which method you may use, and whether you can switch, vary by country and by whether the vehicle is personally or company-owned — worth confirming with your accountant before the year starts rather than after it ends.
Business Versus Personal Use
The split between business and personal mileage is the number everything else depends on, so record it as you go. Two points that catch people out:
Ordinary commuting usually isn’t business mileage. Travel between home and your normal place of work is generally treated as personal in most tax systems, even though it’s plainly work-related. Journeys between workplaces, to clients, or to temporary sites usually do count. The distinction matters, and it’s the most common reason a claim gets reduced.
Round trips need both legs. Log the return journey, or half your business mileage quietly disappears.
Tracking What Your Own Car Costs
Even with no claim to make, a running-cost record is worth keeping — most people underestimate what their vehicle costs by a wide margin, because the expenses arrive separately and never get added up.
Track fuel with the odometer reading each time you fill up, and you get your real consumption rather than the manufacturer’s figure. Add the annual fixed costs — insurance, road tax, servicing, tyres, any finance payment — and divide the yearly total by miles driven, and you have your true cost per mile. That single number makes several decisions easier: whether a longer commute is affordable, whether a second car earns its keep, and whether replacing an ageing vehicle actually saves money or just moves the cost around. It also feeds straight into a monthly budget, where vehicle costs are routinely underestimated.
Frequently Asked Questions
What is a vehicle expense report?
A record of what a vehicle costs to operate — business mileage, fuel, servicing, insurance, and repairs — used to claim reimbursement from an employer or client, to support a tax deduction, or to track personal running costs.
What should a mileage log include?
For each journey: the date, start and end points, the business purpose, odometer readings at the start and end, the miles driven, and whether the trip was business or personal. Totals per month make claiming straightforward.
Is commuting counted as business mileage?
Usually not. Travel between home and your regular workplace is generally treated as personal in most tax systems, while travel between workplaces, to clients, or to temporary sites typically qualifies. Check the rule that applies where you are, since definitions of a temporary workplace differ.
Should I claim a mileage rate or actual costs?
The mileage rate is simpler and needs only a log; actual costs can be worth more for expensive or thirsty vehicles but require receipts for everything and an accurate business-use percentage. Which methods are available to you depends on your country’s rules and whether the vehicle is personally or company-owned — ask your accountant before the tax year starts.
How long should I keep mileage records?
As long as your tax authority can query the return they support — commonly several years. Keep the log itself, not just the summary, along with fuel and repair receipts if you’re claiming actual costs.
Can I keep a mileage log on paper?
Yes. What matters is that it’s contemporaneous, complete, and specific about purpose — a paper log filled in at the time is more credible than a spreadsheet reconstructed at year end. Print the template, keep it in the vehicle, and transfer the totals monthly.
