The Federal Ministry of Finance (BMF) published a groundbreaking letter on November 11, 2025, which fundamentally simplifies the billing of home charging costs for hybrid and electric company cars and clarifies many open questions. For companies with electrified fleets, this brings considerable improvements and legal certainty.
The previous option to reimburse home charging costs as a tax-free flat rate ends earlier than originally planned. The monthly flat rates between 15 and 70 euros are only valid until the end of December 2025 instead of 2030 as previously intended.
What does this mean concretely?
Previously, employers could pay their employees flat-rate amounts for charging their e-company cars at home tax-free without any proof. From January 1, 2026, this is no longer possible. For all home charging electricity costs incurred thereafter: The actually incurred electricity costs must be proven and billed exactly to the kWh instead.
This change makes precise recording and transparent billing of real charging costs essential.
One of the most significant reliefs is the approval of in-vehicle charging data as proof. Previously, only wallbox-based proofs were common.
The new regulation permits:
Almost all modern electric vehicles feature apps that automatically record charging amount and location. This significantly lowers the entry barrier for employees, as an expensive, calibration law-compliant wallbox is no longer mandatorily required.
Important: The BMF explicitly clarifies that calibration law compliance of the wallbox is no longer necessary. However, a separate electricity meter remains a prerequisite to separate the charging amount from general household consumption.
"When determining the electricity costs borne by the employee for charging the operational motor vehicle from the use of a domestic charging device, the amount of electricity is to be proven by means of a separate stationary or mobile electricity meter", states the Federal Ministry of Finance.
Two topic areas that have previously led to many inquiries and uncertainties are now clearly regulated.
Reimbursement for charging with PV electricity becomes simpler
Employees with their own PV system can use the regular household electricity tariff of their electricity provider for billing. A complicated proportional calculation of self-generated solar electricity is no longer necessary. The basic price can also be taken into account proportionally.
There is also clarity now for dynamic electricity tariffs
For electricity contracts with variable prices, the average monthly electricity costs per kilowatt-hour of the energy supplier may now be used as a basis. This pragmatic solution simplifies billing considerably.
The BMF also introduces an alternative to individual electricity price proof: For the period 2026 to 2030, the average total electricity price of the Federal Statistical Office can optionally be used.
What is the average total electricity price?
The Federal Statistical Office publishes the total electricity price for private households every six months. For billing, the value of the first half of the previous year is decisive. For 2026, this value is 0.34 euros per kWh.
The two options at a glance:
Important: The right of choice must be exercised uniformly at the employee level for the entire calendar year. A change during the year is not possible. The BMF letter states:
"In this respect, for the entire calendar year, reference is to be made to the total average electricity price including taxes, levies, and surcharges published for the 1st half of the previous year (value for an annual consumption of 5,000 kWh to less than 15,000 kWh)"
The new regulations create legal certainty and simplifications but at the same time require structured billing. Manual processes with Excel lists and paper receipts are hardly practicable anymore.
What do you need for compliant billing?
NAVIT Home Charging automates these steps and ensures that all requirements of the BMF letter are already met today. Employees upload their proofs via app, the system automatically checks plausibility and prepares the data for payroll.
The BMF letter of November 11, 2025, is significant progress. It removes uncertainties, closes regulatory gaps, and creates practicable solutions for special cases. Although the BMF letter ends a simple practice, it simultaneously creates a legally compliant and future-proof basis for billing home charging electricity in your fleet. Especially for employees with high driving volumes or expensive tariffs, the new regulations can pay off financially. By billing actual consumption, employees can receive a higher reimbursement. In addition, the flexibilization of proofs facilitates documentation.
The new regulations support companies in further electrifying their fleets and offering employees fair, transparent cost reimbursements. For companies, it is now important to review their car policy and internal billing guidelines before the end of 2025 and determine whether they choose the actual electricity price or the electricity price flat rate as a basis.
Early introduction of digital solutions for the automatic recording of kWh-exact home charging allows companies to minimize administrative effort and avoid tax risks. Employers who adapt their processes now and switch to digital solutions create the prerequisite for a transparent and legally secure fleet strategy until the end of the validity period in 2030.
