MilometryFrance has no single mileage rate, it has a table
The barème kilométrique varies by fiscal horsepower and by distance driven. There is no one number, and quoting one is how a French claim goes wrong.
Information générale, pas un conseil. Rédigé à titre d’information générale et exact à notre connaissance au 27 septembre 2026. Les règles fiscales changent et leur application dépend de votre situation. Ceci n’est pas un conseil fiscal, juridique ou financier : vérifiez auprès d’un expert-comptable, d’un conseiller fiscal ou de l’administration fiscale avant de vous y fier.
Ask what France pays per kilometre and you will get a number from somebody. The number will be wrong, or at best right for one car and one annual distance.
The barème is a grid, not a rate
France's barème kilométrique is a table with two axes.
Down one side, fiscal horsepower. French cars carry an administrative power rating, the puissance fiscale, which appears on the registration document. The scale runs from three CV or fewer up to seven CV and above. A larger rating means a higher rate per kilometre, on the reasoning that a more powerful car costs more to run.
Across the other, annual distance. The table bands by how far you have driven for work in the year, and the rate per kilometre falls as the distance rises, in the same spirit as Britain's 10,000 mile step but with more gradations.
So the rate that applies to your journey depends on your car and on your running total. Two colleagues driving the same route on the same day, in different cars, are entitled to different amounts.
Fully electric vehicles have their own scale, higher than the one for other cars, which is a deliberate incentive rather than a costing exercise.
Why this defeats a single headline number
Britain can say "55p" (for the first 10,000 business miles from 6 April 2026, 25p after) because Britain has decided that one figure covers an average car. France has declined to make that simplification, so any sentence beginning "the French rate is" is either quoting one cell of the grid or inventing an average nobody uses.
Milometry does have a France scheme, and it has to work within that limit. It starts from one cell of the grid, the 5 CV figure for up to 5,000 km a year, because that is a common case. For any other car or distance, take the figure for your own row from the official simulator and set it in the app. The grid above 5,000 km is not a simple rate per kilometre at all, so the simulator is the reliable way to get your own number.
What the barème is meant to cover
The rate is inclusive. It is intended to cover depreciation, repairs, tyres, fuel and insurance. That is worth knowing because it settles a recurring argument: you do not claim the barème and then also claim your insurance premium.
Tolls and parking sit outside it and are claimed separately, on evidence. France is a heavily tolled country, and for a driver doing long motorway runs the tolls can rival the mileage in a month.
Against the British system
| France | UK | |
|---|---|---|
| Business rate | A table, by fiscal horsepower and distance | 55p per mile, then 25p (from 6 April 2026) |
| Depends on your car | Yes | No |
| Bands by annual distance | Yes, several | Yes, one step at 10,000 |
| Electric uplift | Yes | No separate rate |
| Tolls and parking | Claimed separately | Claimed separately |
| Covers running costs | Yes | Yes |
The record is the same either way
Whatever the rate, the evidence expected of a French driver is what it is everywhere: the date, the destination, the business reason and the distance, written down at the time rather than reconstructed in the spring.
The table decides what a kilometre is worth. Only the log decides how many kilometres there were.
