How is mileage reimbursement calculated?
When paying mileage reimbursements at the end of the year, an employer doesn’t need to work out the value of each journey or the amount the employee has spent. Employees simply need to use a logbook or app for their reimbursable mileage tracking. Then the employer can simply multiply each employee’s total number of kilometres by their country’s approved per-kilometre allowance, which is also known as the business rate and most commonly as the standard mileage rate.
The standard mileage rate is set by the CRA in Canada. It provides an approved benchmark for tax-deductible reimbursement: in other words, a maximum amount that employers can pay out tax-free.
Employers can set their own figure if they so choose. However, if they exceed the standard mileage rate, the reimbursement will count as regular wages and employees will lose their tax benefits (if they go below the rate, employees in many countries can deduct their difference when filing their tax return).
In Canada, the
CRA business mileage rate
(also known as the automobile allowance rate) for 2024 is as follows:
- 70 Canadian cents for every business kilometre driven for the first 5,000km and 64 cents per kilometre for every kilometre driven afterwards
- In the Northwest Territories, Yukon, and Nunavut, there is an additional 4 Canadian cents per kilometre allowed for travel
Here are some examples of the
optional standard mileage rates in Europe
:
- UK £0.45 per mile
- Germany €0.30 per km
- Belgium €0.42.35 per km
- Spain €0.19 per km
- Portugal €0.36 per km
- Austria €0.42 per km
Some countries have a more complicated version of the standard mileage rate, which depends on the type of car and the distance travelled.
You may have noticed that the mileage reimbursement rate is generally higher than the cost of fuel (in Canada, motorists pay an average of around 0.07 cents per kilometre for their gas, less than an eighth of the CRA mileage rate). In fact, the rate is designed to include the
total cost of maintaining a vehicle.
When an employee uses their car, they not simply paying for fuel expenses—they’re also paying for tax, insurance, and other upkeep costs. Additionally, every trip made t accelerates the depreciation of the vehicle’s value. When calculating the standard mileage rate, the revenue agencies take all these factors into account.
