The company car benefit in kind is the tax and social security valuation of the private use of a vehicle provided by an employer. As soon as an employee can use their company car outside of business trips, this arrangement counts as indirect pay, subject to social security contributions and income tax. A decree dated February 25, 2025 significantly changed the calculation rules that apply from February 1, 2025 onward, replacing a system that had remained almost unchanged since 2002. This guide covers the calculation methods, the rates in force in 2026, and the specific rules for electric vehicles.
What is the company car benefit in kind?
A benefit in kind refers to any good or service provided free of charge or at a reduced rate by an employer, which must be added to the employee’s gross pay. The company car is the most common example in businesses that operate a vehicle fleet. It differs from a plain service vehicle, reserved solely for business trips and returned outside working hours, which does not generate a benefit in kind since no private use is authorized.
The benefit-in-kind classification applies as soon as the employment contract or an internal memo explicitly authorizes private use of the vehicle, including commuting between home and work. This formal authorization, even when only implicit in day-to-day practice, is enough to trigger the valuation requirement, regardless of how much the employee actually uses the vehicle privately.
The legal framework in force in 2026 is based on the decree of February 25, 2025, which replaced rules inherited from 2002. Vehicles made available before February 1, 2025 remain, in some cases, subject to the previous scale until the end of the current contract, while any new vehicle assigned after that date systematically follows the new rules.
How to calculate the benefit in kind: flat rate or actual expenses
The employer has two calculation methods available to value the benefit in kind of a company car, and must keep the same method for the entire current calendar year.
The flat-rate method applies a fixed percentage to the vehicle’s purchase price including tax (if purchased) or to its annual leasing cost (if leased). This is the most commonly used method in practice, since it requires no mileage tracking and simplifies payroll administration.
The actual-expense method values the benefit in proportion to private mileage actually driven, relative to the vehicle’s total annual mileage. This method requires keeping a precise logbook, distinguishing business trips from private ones, which makes it more demanding but sometimes more favorable for employees whose private use remains marginal.
The choice between the two methods mainly depends on the vehicle’s usage profile: a sales representative driving mostly for business purposes often benefits from the actual-expense method, while an executive using their company car in a more balanced mix of business and private trips generally finds the flat rate more convenient.
2026 flat-rate scale by vehicle age and financing method
The flat-rate scale varies depending on whether the vehicle is purchased or leased, its age, and whether the employer covers fuel costs.
| Vehicle situation | Without fuel | With fuel covered |
|---|---|---|
| Purchased, less than 5 years old | 15% of purchase price incl. tax | 20% of purchase price incl. tax |
| Purchased, more than 5 years old | 10% of purchase price incl. tax | 15% of purchase price incl. tax |
| Leased (long-term rental or lease-to-own) | 50% of annual leasing cost | 67% of annual leasing cost |
The purchase price including tax used for a purchased vehicle corresponds to the list price at the time of acquisition, discounts included, without factoring in the vehicle’s subsequent depreciation. For a leased vehicle, the total annual rent billed by the financing provider serves as the basis for calculation, which explains the proportionally higher rate applied in that case.
This scale applies uniformly regardless of the vehicle category (sedan, SUV, estate), the determining factor remaining its purchase price or leasing cost rather than its body type. The choice of vehicle itself, covered in our guide on how to choose the right company car, therefore has a direct impact on the level of benefit in kind generated.
Electric vehicles: the 70% reduction until 2027
Electric vehicles benefit from a notably more favorable regime than combustion-engine vehicles. A 70% reduction applies to the value of the benefit in kind calculated under the standard flat-rate scale, capped at 4,641.60 euros per year in 2026.
Two cumulative conditions govern this favorable regime. First, the vehicle must meet the environmental score required for eligibility to the ecological bonus, which effectively excludes certain models assembled outside the European Union. Second, only fully electric vehicles (Battery Electric Vehicle category) are covered: plug-in hybrids, even with substantial electric range, remain subject to the standard scale with no special reduction.
This tax advantage applies to vehicles made available between February 1, 2025 and December 31, 2027, a temporary window meant to accelerate the electrification of business fleets. Another notable feature: electricity costs covered by the employer for charging the vehicle are not included in the benefit-in-kind calculation over this same period, unlike fuel for a combustion-engine vehicle, which systematically raises the flat rate applied.
In practice, an electric vehicle costs on average 3 to 4 times less in benefit in kind than an equivalent combustion-engine model, making it a significant tax lever for businesses electrifying their fleet, alongside the usage-cost savings covered in our article on how to reduce business transport costs.
Impact on payslips, contributions and income tax
The company car benefit in kind is added to gross pay shown on the payslip, which mechanically increases the base for social security contributions (both employee and employer share) as well as the amount subject to the employee’s income tax. This is applied month by month, at the same pace as salary payments, rather than as a single year-end adjustment.
For the employer, the benefit in kind does not create a direct extra cost beyond the additional employer contributions generated by the increased base. It is an accounting and social security valuation exercise, with no additional financial flow between the business and the employee, unlike a cash bonus.
The amount of the benefit in kind must appear as a distinct line on the payslip, generally specifying the calculation method used (flat rate or actual expenses). An error or omission on this point exposes the business to a reassessment during a social security audit, since the authorities treat the absence of valuation as a way of avoiding contributions owed.
How to reduce the benefit in kind on a company car
Several levers allow businesses to mechanically reduce the amount of benefit in kind generated by their fleet, without giving up company cars altogether.
Switching to electric remains the most effective lever given the 70% reduction available until 2027, provided the necessary charging infrastructure is available at the workplace or the employee’s home.
The choice between buying and leasing also affects the calculation: an older purchased vehicle (more than 5 years old) generates a reduced benefit in kind of 10% of its purchase price, versus 15% for a recent vehicle, which can influence certain fleet renewal policies. Financing options are covered in our guide on long-term car rental for business, which compares the costs and constraints of long-term rental versus purchasing.
Not having the business cover fuel costs also lowers the flat rate applied (15% instead of 20% for a recently purchased vehicle), at the cost of shifting that expense to the employee through a mileage allowance or a fuel card restricted to strictly business use. This choice should fit within a coherent fleet policy, documented in a car policy that sets the rules applicable to all employees concerned.
Frequently asked questions
How is the benefit in kind of a company car calculated?
Two methods are available: the flat-rate method, which applies a percentage of the vehicle’s purchase price or rental cost, or the actual-expense method, proportional to documented private mileage tracked in a logbook. The employer chooses one of the two methods and must keep it for the whole calendar year.
What is the 2026 flat-rate scale for the benefit in kind?
For a vehicle bought less than 5 years ago, the flat rate is 15% of the purchase price including tax, or 20% if the employer covers fuel costs. Beyond 5 years, the rate drops to 10%. For a leased vehicle, the rate is 50% of the annual leasing cost, or 67% with fuel included.
Is the benefit in kind different for an electric vehicle?
Yes. Electric vehicles benefit from a 70% reduction on the value of the benefit, capped at 4,641.60 euros per year in 2026, provided the vehicle meets the environmental score required for the ecological bonus and is made available between February 1, 2025 and December 31, 2027. Plug-in hybrids are excluded from this special regime.
Who has to pay for fuel under the benefit in kind rules?
Fuel can be covered either by the employer or the employee. If the company provides it, the flat rate applied to the vehicle increases (20% instead of 15% for a purchased vehicle, 67% instead of 50% for a leased one). Electricity costs covered for charging an electric vehicle, on the other hand, are not included in the benefit-in-kind calculation until December 31, 2027.
Does the benefit in kind change depending on whether the vehicle is bought or leased?
Yes, the flat rates differ depending on the financing method. A purchased vehicle is valued based on its purchase price including tax, while a leased vehicle (long-term rental or lease-to-own) is valued based on the annual leasing cost, with proportionally much higher rates (50% to 67% versus 10% to 20%).
