KILOMETER SCALE. Declaring your mileage expenses for their actual amount could save you a lot of money. How to calculate them? What gain with the increase in the scale in 2023? All info.

[Updated April 3, 2023 09:28] The 2023 declarative campaign is fast approaching. And this year, the increase in the mileage scale is one of the small novelties. Indeed, the latter was revalued by 5.4% for the two million households concerned. For example, if you have a vehicle with a fiscal horsepower of 6CV and travel 20,000 kilometers per year as part of your job, you will need to apply the following calculation: 20,000 x 0.425 (applicable scale) = 8 500. Or 8,500 euros in mileage allowances will be deducted from your tax return.

To claim this device, it is necessary to use his car, motorcycle, or even his electric vehicle for professional purposes, and to declare his mileage expenses. If this is your case, it can make a lot of money. For example, this “can represent more than 100 euros for a single person who earns 2,900 euros”, specified the Ministry of Economy and Finance to AFP. So, it’s up to you to see which is more profitable between taking advantage of the 10% flat-rate deduction applied automatically when you declare your income, or declaring your professional expenses for their actual amount.

The mileage allowance is calculated according to the distance traveled between your home and your place of work but also the fiscal power of your vehicle, a data to easily find on your car registration document. You can find the scale applicable to cars below with two examples?

This 2023 scale will also serve as a reference for setting the amount of flat-rate mileage allowances paid by employers to their employees, when the latter use their personal vehicle for business trips. These allowances are exempt from social contributions and income tax, without specific supporting documents, within the limit of the kilometer scale.

Choosing to declare your professional expenses for their actual amount, to the detriment of the automatic flat-rate deduction of 10% involves various administrative constraints.

The taxpayer concerned must identify all the expenses incurred in respect of his professional activity (meals, transport, clothing). Then, he is required to be able to justify all of these expenses, and that they are necessary for your professional activity, through invoices to be kept in a safe place. Also, the taxpayer must be able to present a complete list of all expenses incurred, to attach a detailed note to the tax return. To be eligible for actual costs, the total amount must exceed the flat rate deduction ceiling of 10% (12,828 euros).

Remember that these scales are calculated according to the power of the vehicle and the number of kilometers traveled. They take into account in particular the depreciation of the vehicle, repair and maintenance costs, tire costs, fuel consumption and insurance premiums. It is possible to add loan interest in the event of the purchase of a vehicle on credit, toll fees and parking fees. These travel expenses relate in particular to transport from home to the place of work and transport during working hours.

Good news if you want to invest in an electric vehicle.
