EV charging expense claims: how to claim home charging of a company car in Europe, and what evidence to keep

A driver who charges a company EV at home can claim the electricity back from the employer. In most European countries the claim must be based on the kWh the car actually used, multiplied by a justified price per kWh: the driver's own contract price, or an official rate where the country publishes one (Belgium, Germany, Switzerland, the UK). Without measured kWh and a defensible price, the payment stops being a reimbursement and becomes taxable pay.

This guide is written for payroll, finance and fleet teams, and for the drivers who submit the claims. It compares the rules in nine European countries, lists what a valid claim must contain wherever you are, shows with euro examples why one flat rate pays some drivers too much and others too little, and explains how companies such as the 200+ clients of Voltaback replace the monthly claim with an automatic statement.

How an EV charging expense claim works

Home charging is the only fuel a company pays for after the event. With a petrol or diesel car, the driver fills up with a fuel card and the company sees every litre. With an EV, the electricity comes from the driver's own home supply, on the driver's own bill, so the company has to pay it back.

Every country answers three questions in its own way:

• Which price? An official rate per kWh (Belgium, Germany), a monthly lump sum (Switzerland), a per-mile rate (UK), or the actual price of each driver's contract, which is accepted everywhere and is the only option in the Netherlands, Luxembourg, Italy, Spain and Portugal.
• Which kWh? Only the kWh that went into the company car, never the household's own consumption.
• Which evidence? A record the tax office or social security auditor can check: measured kWh, the tariff, and the link to a specific vehicle and driver.

If the price is too high or the evidence is missing, the payment becomes pay, with income tax and social contributions on top. Our guide to flat rate versus actual cost covers the choice of method in depth. This article focuses on the claim itself: how it is built, what it contains and how to make it audit-proof.

The rules country by country

The sections below explain each line. Whatever the country, the same core of evidence makes a claim hold up.

What every valid claim must contain

Across Europe, auditors ask the same questions: is the amount linked to the company car, is it based on measured energy, is the price justified, and can it be reproduced from the records? A claim that answers yes to all four survives an audit almost anywhere.

Two documents complete the file: the driver's electricity contract or latest bill (for the price) and the company's charging policy (which method, which rate, who approves). In Germany, the Bavarian tax office stated in June 2026 that the quantity must come "directly and unchangeably" from the charging data: a spreadsheet in which the driver types the kWh is not accepted.

Belgium: the CREG flat rate as a ceiling

In Belgium, the employer may reimburse home charging of a company car at the actual cost of the driver's contract or at a flat rate per kWh, set every quarter by FPS Finance on the basis of CREG prices, by Region of the driver's home. The framework is circular 2024/C/77 and its quarterly addenda; circular 2026/C/86 sets the fourth quarter of 2026. Source: CREG.

The flat rate is a ceiling, not the price drivers pay. Charging at night on a dual-rate contract costs about €0.24 to €0.25 per kWh, well below the Q4 2026 ceilings of 32.25 c€ in Flanders, 36.88 c€ in Brussels and 37.79 c€ in Wallonia.

The evidence rule is strict: the car's consumption must be measured separately and verifiably. Since 1 January 2025, a new measuring system must meet accuracy class B or an equivalent. An estimate based on mileage or on the household bill does not qualify. Because the rate changes each quarter, a Belgian claim must use the rate of the quarter in which the charging took place, not the one in force on the payment date.

Netherlands: actual cost per employee, no flat rate

In the Netherlands, reimbursing the electricity used to charge a company car at home counts as intermediate costs (intermediaire kosten): not wage, and untaxed, as long as the amount does not exceed what the driver really paid. It sits outside the bijtelling, which taxes private use of the car itself.

The Belastingdienst knowledge group states that the full actual cost per kWh must be worked out per employee, fixed and variable costs included. An average price for everyone is rejected. Source: Belastingdienst, kennisgroep KG:204:2024:13.

So a Dutch claim needs, per car: date, kWh, price per kWh and amount. Drivers on a dynamic hourly contract need the hourly price of each session, and those with solar panels need a reasonable valuation of the self-generated kWh. Any surplus above cost is taxed as wage.

Germany: contract price or Strompreispauschale

The BMF letter of 11 November 2025 gives the employer two ways to value home charging of a company car, chosen per calendar year:

• Option A: the driver's individual electricity price, including a proportionate share of the standing charge.
• Option B: the Strompreispauschale, the average household price published by Destatis for the first half of the previous year, rounded down. It is €0.34 per kWh for 2026. Applying the same rule to the Destatis figure for the first half of 2026 gives €0.32 per kWh for 2027.

Both options require measured kWh, from a separate stationary or mobile meter, which explicitly includes a wallbox meter or the car's own meter. Source: BMF letter of 11 November 2025. The reimbursement is tax-free under § 3 No. 50 EStG as a refund of the employer's own costs.

Switzerland: the CHF 60 lump sum or actual cost

In Switzerland, expenses are governed by the employer's expense regulation, approved by the canton where the company is based. The model regulation of the Swiss Tax Conference allows a lump sum of up to CHF 60.– a month for charging an electric company car at home. The alternative is actual cost: kWh charged multiplied by the employee's tariff, which varies a lot between municipalities. Source: SSK/CSI model expense regulations 2026, ElCom electricity prices by municipality.

The lump sum is simple, but it is fixed regardless of mileage, so high-mileage drivers are often underpaid. A lump sum that is not covered by an approved regulation is salary for tax and social security.

Luxembourg, Italy, Spain and Portugal: no official rate

These four countries publish no official price per kWh for home charging of a company car, so the claim must rest on actual cost.

• Luxembourg: kWh charged multiplied by the price in the employee's contract. A monthly allowance above the real cost creates taxable salary. With almost half of employees living across the border, the contract price differs widely within one fleet.
• Italy: the Agenzia delle Entrate ruled (interpello answer no. 421 of 25 August 2023) that reimbursing home electricity for a company car in mixed use is a refund of an expense borne by the employee and therefore employment income under art. 51 TUIR, even when measured precisely. The claim still needs measured kWh and the bill price, because it goes through payroll. Source: Agenzia delle Entrate, answer no. 421/2023.
• Spain: there is no exempt amount per kWh. By analogy with the tax office's doctrine on fuel for company cars (DGT V2799-23), energy for business journeys is a company expense, while energy for private use is income in kind. The claim must show the business share. The €0.26 per km allowance applies only to the employee's own car. Source: DGT rulings search, IRPF Regulation.
• Portugal: no fixed legal value either. The company can reimburse a documented expense with an objective allocation criterion; binding information from the tax authority deals with the treatment of charging costs. Source: AT, binding information 25762.

UK: the AER per mile, or actual cost

The UK uses a different logic: a rate per business mile, not per kWh. The Advisory Electricity Rate is 7p per mile for home charging and 15p per mile for public charging since 1 September 2026, reviewed every quarter. Ordinary commuting is private travel, so only business miles count, and the claim must split miles powered by home and public charging. Source: HMRC advisory fuel rates.

Alternatively, the employer can reimburse the actual cost of the electricity used to charge the company car: HMRC exempts it under s.239 ITEPA 2003, as long as it covers only the company car. Source: HMRC EIM23900. UK readers will find the full detail, including the business mileage evidence, in our UK edition.

Why one flat rate overpays some drivers and underpays others

A flat rate is an average. Drivers are not. Their price per kWh depends on the country, the region, the contract and the time they charge.

Belgian example. A Brussels driver charges 2,500 kWh a year at night at about €0.24 per kWh, so €600 of real cost. At the Q4 2026 Brussels ceiling of 36.88 c€, the claim would be €922. Paying the ceiling is allowed, but across 50 cars the gap is about €16,100 a year.

German example. Two drivers each charge 3,000 kWh a year at home.

The first driver's €300 is legal under option B, but it is money the company did not need to spend. The second driver subsidises the company car with his own money, which is a reliable source of complaints. The same pattern appears with the Swiss lump sum and the UK per-mile rate.

Multi-country fleets. In a fleet spread across Belgium, Germany and the Netherlands, three different methods apply: a regional ceiling, a national flat rate or the contract price, and the contract price only. A single group-wide amount cannot be right in all three.

When a claim becomes taxable pay

The risk is the same everywhere: an amount that is not linked to measured kWh, business miles or a justified price is pay.

• Belgium: kWh that are not measured separately, or that include household use, are a taxable benefit subject to ONSS / RSZ contributions.
• Netherlands, Germany, Luxembourg: the part above the real cost, or a payment without measured kWh, is taxable wage.
• Switzerland: a lump sum outside an approved expense regulation is salary.
• Italy: the reimbursement is employment income in any case, so the risk is wrong withholding rather than requalification.
• UK: a round-sum allowance, or an AER-style payment above actual cost without evidence, is earnings with PAYE and Class 1 NIC.

The other common mistake is to accept claims built from the household bill. A household bill mixes the car with heating, cooking and everything else, and no tax office accepts that as proof of the car's consumption.

Business, private and public charging

Three situations come up in almost every claim review.

Private journeys and holidays. In most countries, the energy for private trips in a company car is part of the car benefit the driver is already taxed on, so the employer can reimburse it at cost. Spain is the main exception, where the private share is income in kind. In the UK, the AER only covers business miles, while the actual-cost route covers all home charging of the company car.

Public charging paid by the driver. It is a separate line, backed by the operator's receipt or statement, and reimbursed at the price actually paid. Better still, a charging card paid directly by the company removes the claim altogether.

The employee's own car. When an employee uses a private EV for business trips, the rules change: the employer pays a per-km allowance (for example €0.26 per km in Spain, or 55p per mile for the first 10,000 business miles in the UK) and the electricity is included in it. Mileage records then matter more than kWh. Our guide to keeping a business mileage log lists the fields each country expects.

Cross-border drivers and multi-country fleets

Cross-border work is common in Europe: Luxembourg, Switzerland, the Netherlands and Belgium all employ large numbers of people who live in a neighbouring country. Two different rules then meet.

• The tax and social security rules of the payment generally follow the country where the employee is paid and insured, so the claim method is set by the payroll country.
• The price per kWh comes from the electricity contract in the country where the driver lives and charges.

A Luxembourg employer with a driver living in Belgium therefore reimburses Belgian kWh at a Belgian contract price, under Luxembourg payroll rules. Where the payroll country uses a regional flat rate, as Belgium does, check with your payroll provider which rate applies to a driver living abroad. For group fleets, one policy can cover all countries if it says "actual cost, or the national official rate where one applies" and leaves the price to each driver's file.

For drivers: how to get paid correctly

If you drive a company EV, four habits protect you:

• Give your employer your real contract, including any night or dynamic rate, and update it when you switch supplier.
• Charge the company car at home on its own record: if a second EV or a heat pump shares the supply, the measurement must come from the car or a dedicated meter.
• Keep public charging receipts and claim them separately.
• Check your payslip: the reimbursement should appear as a non-taxable item in most countries.

If you are paid a flat rate below your real cost, ask whether the policy allows actual cost on evidence: in Germany, Belgium and the UK, it does.

A sample monthly claim

Here is what a complete monthly claim looks like for a Dutch driver, built on actual cost:

The same structure works in every country: only the price line changes (CREG ceiling, Strompreispauschale, contract price or bill price).

How many kWh a company EV charges at home

Before checking a claim, it helps to know what a plausible figure looks like. A typical company EV uses 16 to 20 kWh per 100 km in the battery, plus about 10 % charging losses at home, so roughly 18 to 22 kWh per 100 km drawn from the wall. Most company car drivers charge 60 to 80 % of their energy at home.

Assumption: 20 kWh per 100 km drawn from the socket, losses included. Winter months are 10 to 20 % higher than summer months. A claim far outside this range, for example 600 kWh in a month for a driver at 15,000 km a year, deserves a question before payment: it may include a second household car or a heat pump.

How to work out a driver's real price per kWh

When the method is actual cost, the right figure is the marginal price of one more kWh, not the average of the bill. It is the sum of the energy price, the per-kWh network charge, the per-kWh taxes and levies, and VAT. Fixed standing charges are excluded in most countries, because they are paid whether the car charges or not; Germany's option A is the exception, as it allows a proportionate share.

• Dual-rate contracts: use the night or off-peak price if the car charges at night, which is what most drivers do when the car can schedule it. In Belgium, the night bi-hourly price is about €0.24 per kWh; in Luxembourg about €0.19 at night on a dual-rate offer.
• Single-rate contracts: the variable price per kWh on the bill, about €0.32 in Germany in 2026 for a typical contract.
• Dynamic hourly contracts: the hourly price of each session plus the fixed per-kWh mark-up and taxes.
• Solar panels: kWh from the roof have a value too (the feed-in tariff the driver gives up), but they are not free and not priced at the grid rate either.

The price must be updated when the contract changes, and at least once a year. Our article on what a home kWh really costs shows the full breakdown by country.

Setting up the claim process, step by step

For payroll and fleet teams, a clean process has six steps:

1. Write the charging policy: method (actual cost or official rate), which kWh are covered, how public charging is handled, who approves.
2. Collect each driver's price basis at onboarding: contract or latest bill, and the meter type.
3. Fix a monthly cut-off: sessions from the 1st to the last day of the month, claims due by the 5th, paid with the next payroll.
4. Check plausibility: kWh against mileage, price against the contract, no overlap with public sessions.
5. Pay through payroll under a dedicated non-taxable code (or a taxable one in Italy), so the amount appears on the payslip.
6. Archive the file per driver and month for the retention period of the country.

Manual claims cost more than they seem. At 15 minutes for the driver and 10 minutes for approval and payroll, a 100-car fleet spends around 500 hours a year on charging claims, before any correction.

Accounting and VAT

The reimbursement is a vehicle running cost for the company, booked with the other fuel and energy costs of the fleet. VAT is a frequent question: because the electricity invoice is addressed to the employee, not to the company, the company generally cannot recover input VAT on home charging reimbursements. The amount reimbursed is therefore the price including VAT. Check the national rules with your tax adviser if your fleet is large, as the treatment of company car energy differs between countries.

Five checks before approving a claim

1. Is the vehicle a company car? Private cars follow the per-km allowance, not kWh reimbursement.
2. Do the kWh come from a measurement, not from the driver's estimate or the household bill?
3. Is the price the one in the driver's file, and has the contract changed since?
4. Is the period correct, especially in Belgium where the rate changes each quarter?
5. Are public sessions excluded from the home total and reimbursed separately with receipts?

A claim that passes these five checks is defensible in front of a tax inspector in any of the countries above.

Data protection: what the claim may and may not contain

A charging claim is personal data under the GDPR (in Switzerland, the nLPD), so the rule of data minimisation applies: collect what the reimbursement needs and nothing more.

• Needed: driver, vehicle, period, kWh, price, amount, and the fact that the session took place at home.
• Not needed: the GPS position of the car, the exact address of each session beyond the registered home, journey histories, or charging times in more detail than the tariff requires.

Where a works council exists, any system that can monitor employees may require its agreement, for example under § 87(1) No. 6 of the German Works Constitution Act. Choosing a tool that never sends location data to the employer makes that discussion much shorter. It is also simpler to explain to drivers, who are more willing to connect their car when they know the company sees kWh and euros, not where they went.

How to remove the monthly claim entirely

The best claim is the one nobody has to fill in. When each home charging session is measured automatically and priced at the right rate, the driver no longer submits anything and payroll receives a ready statement.

That is how Voltaback works. The software reads each home charging session from the car's own data, for more than 48 car brands, and applies the rate your policy chooses: the driver's real tariff, or the national rate where one exists. Voltaback relies on the home's MID-certified meter, not on a standalone cable meter. The measurement has been audited by an independent third party at a 1.22 % relative error, and the kWh cannot be edited by the driver.

• For the driver: no receipts, no spreadsheet, a statement each month. See the driver's guide to charging a company car at home.
• For payroll: one statement per vehicle, kWh, price and amount, ready for the payroll run and for an audit, in every country of the fleet.
• For the company: no hardware to buy, ISO 27001 certified since 2 December 2025, GDPR compliant, and the company never receives the drivers' location.

The full process, from policy to payroll, is set out in our guide to managing home charging reimbursement. To see the cost for your own fleet, use the home charging cost simulator, or read how home charging reimbursement works with Voltaback.

Turn claims into a monthly statement

Expense claims for EV charging are a symptom: the company lacks the data, so it asks the driver for it. Once each session is measured and priced automatically, payroll gets an audit trail in every country and drivers get paid exactly what they spent.
