Since 1 January 2026, the monthly flat rates for home charging are gone. Companies that reimburse employees for charging a company car at home must now document and settle the kilowatt hours actually charged. The legal change is short. The operational consequence is not.
Home charging for company cars in Germany has moved from a payroll line item to a data process. What used to be a fixed monthly amount is now a chain of steps involving the driver, the fleet team, and payroll, with proof requirements at every stage. The question most fleet managers are asking is no longer what changed, but how to organise it. This guide covers what the change means in practice for companies operating company car fleets in Germany.
What you get in this article:
Until the end of 2025, home charging reimbursement was straightforward. The employer set a monthly flat rate, transferred the amount, and the topic was closed. Depending on vehicle type and whether the employee could also charge at the workplace, that flat rate sat between EUR 15 and EUR 70 per month. No proof of consumption was required.
Since January 2026, every kilowatt hour is subject to documentation. The flat rate has been replaced by a data process with defined requirements.
What has to be documented now:
Companies that cannot meet these requirements cannot reimburse tax-free, and they carry the exposure in a wage tax audit.
The change also moves the fleet function into a new position. Previously, fleet managed vehicles. Now fleet owns a process that sits between drivers and payroll. That is more responsibility, and it is also the point at which fleet electrification finally gets a transparent cost base.
Three points that regularly get missed:
Private vehicles are not covered. If an employerreimburses home charging for an employee’s own car, that is taxable wages. Anystatement about tax-free home charging reimbursement has to name thisdistinction.
Under the 1-%-Regelung, § 3 Nr. 46 EStG does not addanything. Where the benefit in kind is determined on the flat-rate basisunder § 8 Abs. 2 Satz 2 EStG, employer-supplied charging electricity is alreadycovered by that calculation.
The additionality requirement applies. Under § 8Abs. 4 EStG, the reimbursement has to come on top of contractual pay. Salarywaiver and salary conversion are excluded.

Most existing company car policies state a flat monthly amount for home charging and stop there. That is no longer sufficient. The car policy now has to decide whether the process is up and running or whether every month it produces administrative loops between drivers, fleet, and payroll. Here are the points that have to be included in the car policy:
Accepted forms of proof: State explicitly what sources drivers can use to document their home charging, e.g. a calibrated wallbox, a wallbox with an MID meter, a separate mobile electricity meter, or the vehicle’s internal meter via the manufacturer app or OBD data.
Mandatory fields per submission: Metered kWh, electricity price, pro-rata standing charge where the individual tariff applies, period or timestamp, and unambiguous allocation to vehicle and driver.
Electricity price model: Individual tariff including the mandatory standing charge share, or the statutory flat rate of EUR 0.34 per kWh. The choice belongs in the policy, and it applies for the full calendar year.
Submission deadlines: Fixed cut-off dates prevent late submissions from pushing into the payroll run. Automated reminders help.
Digital submission route: Define where proof is submitted: a fleet portal, fleet software, or an app-based tool. Email is workable and creates the most manual sorting. Without a defined route, parallel channels appear.
Special cases: PV charging, dynamic electricity tariffs, and charging from a household socket each need an explicit rule. Section 5 covers all three.
Review responsibilities: Fleet checks plausibility, HR and payroll handle the tax treatment. The handover between them has to be written down.
Give drivers a working examples showing what a complete submission looks like. A single example prevents more queries than three pages of explanation.
The most frequent error in practice is, that employees submit only the working price per kWh from their electricity contract and leave out the monthly standing charge. The standing charge is a fixed component of every German electricity contract and has to be included pro rata. Leaving it out creates a systematic shortfall for the employee and an incomplete documentation trail for the employer.
This example shows the scale:
Across 50 electric company cars, that is EUR 6,000 per year.
An employee’s own written statement of the electricity price is not sufficient proof. The price has to come from the supply contract or the tariff app.
When reimbursement depends on verifiable data, payroll becomes the point where everything has to line up. Every reimbursement has to appear correctly in the payroll account, tax-free, auditable, and traceable. This is where unclear responsibilities cost the most.
The fleet manager checks the plausibility, e.g. is the kWh volume consistent with mileage, is the electricity price within a realistic range, are all mandatory fields present, or is the vehicle allocation unambiguous. HR and payroll check the tax treatment, e.g. is the documentation complete for the payroll account, is the record correct, is archiving in place.
For the handover, all departments must agree on one data format, for example CSV or Excel with defined columns, and specify which fields are mandatory, set fixed handover dates so the payroll run is not compressed, and put an approval step inside fleet so only checked data moves on, with a record of who approved what and when.
The problems that show up without this are consistent. PDFs without timestamps, a different file format from every driver, missing standing charge figures, late submissions, and no clear owner for final sign-off. For fleet management that means to bring in HR and payroll early. Where fleet and payroll design separately, the two designs meet for the first time in the payroll run, which is the worst possible place for that conversation.
A screenshot from a vehicle app looks complete at first glance: kWh charged, date, sometimes the location. However, several questions can stay open. Without a VIN check, there is no unambiguous link to the company vehicle. Without location context, there is no way to tell whether the session happened at home or at a public charge point that should be billed separately. Screenshots can also be edited.
Before data goes to payroll, fleet should apply a first plausibility check. An employee driving 300 kilometres in a month should not be charging 500 kWh, since electric cars typically consume 15 to 25 kWh per 100 kilometres. An electricity price of EUR 0.15 per kWh would be unusually low and EUR 0.60 per kWh unusually high, outside dynamic tariffs with peak-load pricing. Timestamps have to be present, and the vehicle allocation has to be readable from the number plate or the VIN.
Automating the check
Home charging management tools can run parts of this automatically: comparing metered volume against mileage, flagging outliers, and applying the correct electricity price per driver. Trust is thereby not an internal control system in tax terms. The employer, not the employee, carries the liability for tax-free reimbursements.
This is the point fleet managers most often underestimate. Proof of home charging has to be archived centrally by the employer in a form that survives an audit. Storage on employees’ private phones does not meet that standard. If documents cannot be produced during a wage tax audit, the company is liable, not the employee.
The exposure is straightforward to size. Across 50 electric company cars at an average reimbursement of EUR 80 per month over three years, the total reimbursed amount is EUR 144,000. If the underlying proof is missing, that full amount can be reassessed as taxable wages, plus interest and audit costs.
What to settle in writing: where documents are stored, who owns the archive, and how retrievability is guaranteed for the full retention period. Systems that store proof centrally with timestamps and version history remove this question from the fleet team’s desk.
Companies have to decide how home charging is priced. The choice drives the administrative load for drivers, fleet, and payroll, and it belongs in the car policy.
One point first, because it is the most common misreading of the 2026 rules: the choice concerns the price, never the quantity. The kWh volume has to be metered in every case, using a separate stationary or mobile meter, which expressly includes the vehicle’s internal meter. There is no version of the 2026 rules in which measurement can be skipped.
Employees are reimbursed at their real tariff. With this method, the employee provides the supply contract. The working price per kWh comes from that contract and the monthly standing charge is included pro rata. Tariff changes have to be reported and documented.
This gives the most accurate result per employee and is attractive for drivers with cheap tariffs or a PV system. It also means contracts have to be reviewed, standing charges calculated, and changes tracked, with a different calculation per driver reaching payroll.
For small fleets of up to roughly 20 electric company cars with widely differing tariffs, that effort can be worth it.
The Strompreispauschale is a fixed price per kWh set by reference to published statistics. For 2026, it is EUR 0.34 per kWh, derived from the Statistisches Bundesamt figure for the first half of 2025 of 34.36 cents per kWh, rounded down to the full cent. Here, no electricity contracts have to be collected or checked. Tariff changes are irrelevant and only the metered kWh volume has to be documented.
The rate is set annually, always from the first-half figure of the previous year, so it changes every January. The flat rate is available from 1 January 2026 to 31 December 2030.
It is less precise than the individual tariff. It can sit below the real cost for employees on expensive contracts, for example at EUR 0.40 per kWh, and above it for employees with cheap tariffs or a PV system. For fleets from about 20 vehicles upwards it is the option that keeps the process stable.
Some companies let employees pick between the individual tariff and the flat rate. That accommodates different situations, and it also means running two processes in parallel, with a higher query volume. The choice has to be exercised uniformly per employee for the entire calendar year. Switching mid-year is not possible.
For most companies, the flat rate is the pragmatic answer. It simplifies settlement, makes costs predictable, and removes the tariff conversation entirely.
Three situations need their own wording in the car policy. The new regulation on home charging is clear on all three, which makes them easy to settle in advance.
Employees with their own photovoltaic system can use the regular household tariff from their electricity contract, regardless of how much of the charged electricity actually came from the roof. That means no split calculation between grid electricity and solar electricity and the regular household price applies, for example EUR 0.32 per kWh. The standing charge can be included pro rata.
A suggested wording for the car policy would be the following: “Employees with a private PV system settle at their regular household electricity tariff. A split between grid and solar electricity is not required.”
With variable-price contracts such as Tibber or aWATTar, the price changes hourly. Settling per kWh at hourly prices would be extremely cumbersome. Hence, employees may use the average monthly price per kWh shown in their tariff app, including the pro-rata standing charge. An hourly settlement is not required.
In this case, the wording for the car policy could be like this: “For dynamic electricity tariffs, the average monthly price per kWh from the tariff app applies. Hourly settlement is not required.”
Not every employee has a wallbox. To accomodate this, charging from a standard household socket is permitted, when the charging history from the vehicle is available in full, e.g. from the vehicle app with kWh, date, and time. Further, evidence of the electricity price, either the contract or the flat rate, is needed.
In the end, what matters is the completeness and plausibility of the data, not the hardware at the charging point. Someone charging from a socket has to provide the same evidence as someone with a wallbox.
In the car policy, this needs to be stated: “Charging without a wallbox, for example from a household socket, is permitted. The charging history from the vehicle’s internal meter is accepted as proof, provided all mandatory fields are present.”
Leaving these three cases unwritten produces the same three questions from every driver. Each one costs fleet time and leaves the employee unsure whether their submission will be accepted.

Get infoVehicle apps and simple meter setups can be sufficient today. However, as the share of electric vehicles in the fleet grows, the case for automation grows with it. Here are ways to achieve that.
Smart wallboxes record charged volumes automatically and can pass data directly to fleet or payroll systems. That removes manual submission entirely and produces consistent data quality.
Purchase costs run from around EUR 500 to EUR 2,000 depending on model, installation by a qualified electrician is required, and tenants may need landlord approval. Employees who move frequently or have no dedicated parking space are hard to cover this way.
Smart wallboxes are a good choice for high-mileage drivers that have their own parking space at home.
A home charging management tool centralises submission and preparation of proof without new hardware. Here is how it works in practice:
Some companies plan to handle settlement through spreadsheets and email submissions. This can work for small companies that have up to ten vehicles, but it stops working shortly after that. The admin time spent in fleet and HR can be high, partly due to an high error rate from incomplete submissions. Manual processes usually also do not have systematic plausibility checks or a central, audit-ready archive. In the end, there is no path to scale as the fleet grows.
Step 1: Revise the car policy
Define which proof formats are accepted, which fields are mandatory, which electricity price model applies, how the three special cases are handled, and when submissions are due. Add a worked example.
Fleet leads, with HR and, where relevant, legal. Have the revised policy reviewed by a tax adviser before it goes out internally.
Step 2: Define the fleet-to-payroll interface
Fix responsibilities in writing: fleet checks plausibility, HR and payroll check tax treatment. Agree the data format and columns, the handover dates, and who gives final approval. Define what happens with incomplete or late submissions.
Fleet leadership and HR or payroll leadership own this jointly. A two to three hour joint session settles most of it.
Step 3: Brief employees
A 15 to 20 minute session or short video covers what changed, what has to be submitted, and by when. One worked example does more than a five-page PDF. An FAQ covering the ten most common questions removes most of the query load, and a named contact handles the rest.
Fleet and HR share this. Use the internal channels that already work.
Step 4: Evaluate a digital solution
Define requirements first: plausibility checking, audit-ready archiving, payroll integration. Request demos from two or three providers. Run a test with five to ten employees over at least four weeks. Calculate one-off and per-user running costs.
Fleet leads, with IT and, where relevant, procurement. Ask for reference customers with a comparable fleet size.
Step 5: Run a pilot
Pick ten to twenty employees covering high and low mileage, with and without a wallbox. Run the full loop once: submission, review, handover to payroll. Identify what works and where queries arise, then adjust the policy, the worked example, and the deadlines. Ask the pilot group what was unclear.
Allow four to six weeks. Finding the friction at fifteen drivers is considerably cheaper than finding it at two hundred.
Step 6: Extend to the full fleet
Move in stages rather than switching 200 vehicles at once, for example 50 per month. Keep collecting feedback, keep adjusting, and communicate regularly on what is working. Set up support: who answers questions, through which channel.
Fleet leads. Plan a buffer for the first months. Effort is usually higher than expected and settles after three to four months.
The car policy carries the process. Accepted proof formats, mandatory fields, the price model, deadlines, and the three special cases all need explicit wording. Time spent here is repaid in queries that never arrive.
The fleet-to-payroll handover is where it succeeds or fails. Unclear responsibilities produce returns, delays, and payroll pressure. One joint session between fleet and HR settles most of it.
Manual settlement does not scale. Spreadsheets and email work at ten vehicles. They do not produce a plausibility check, an audit-ready archive, or a data base for reporting.
For fleets in Germany running more than about twenty electric company cars, the statutory flat rate combined with a defined submission route is the combination that keeps monthly effort predictable.
