Company car home charging in Belgium: who pays?

Charging a company car at home does not come out of your pocket, in principle. The employer reimburses the electricity at the CREG rate, a per-kWh cap set every quarter and per Region. In Q3 2026 it runs from 32.22 c€/kWh in Flanders to 37.83 c€ in Wallonia. Two conditions apply: a smart charger and a clause in the car policy.

Who pays for a company car charged at home?

The employer. When you charge a company car at home, the electricity used by the car is reimbursed by the employer if the car policy provides for it. That reimbursement is not an additional taxable benefit as long as it stays below the CREG rate for your Region. You remain taxed only on the car's benefit in kind, known locally as the ATN or BIK.

The CREG rate is the average all-in price of residential electricity, energy, grid, levies and VAT included, calculated by the Commission for the Regulation of Electricity and Gas. The FPS Finance (the federal tax authority) uses it as a ceiling: below it, the reimbursement is fiscally neutral; above it, the excess becomes taxable. This mechanism is what keeps Belgian fleets running, where the company car remains a pillar of salary packaging.

In practice, the employer multiplies the kWh charged at home by your Region's rate. A Walloon driver who charges 200 kWh in a month in Q3 2026 receives €75.66 (200 × €0.3783), with no tax and no social contributions. According to the CREG, this amount tracks the real price paid by households, which is why it moves every quarter.

How much can the employer reimburse per kWh in 2026?

Between 31 and 38 cents per kWh, depending on Region and quarter. The lowest cap is always in Flanders, the highest in Wallonia. For 2026 the rise has been continuous since January, after the easing at the end of 2025.

Rates in euro cents per kWh, maximum caps per Region (FLEET.be, May 2026). In plain terms: for the same consumption, a Walloon driver is reimbursed about 17% more than a Fleming, simply because residential electricity costs more there. It is not a bonus, it is an alignment on the real market price.

The rate is no fixed annuity. In Q4 2025 it had fallen to 34.57 c€/kWh in Wallonia, against 38.43 c€ the previous quarter. A driver charging 200 kWh a month saw the reimbursement drop from €76.86 to €69.14, nearly €8 less a month, with no change in habits.

Do you need a smart charger to be reimbursed?

Yes, that is the central condition. A tax-free reimbursement requires a charger that meters precisely the kWh sent to the car, separately from the household's consumption. Without that measurement, the employer has no reliable way to justify the amount, and an audit reclassifies the reimbursement as a taxable benefit.

The charger must carry a communication system that reports consumption to the employer, or a verifiable intermediate meter. Since 1 January 2025, any charger bought, rented or leased must include kWh metering meeting minimum accuracy conditions, per the FPS Finance. A figure jotted on a notepad will not survive an audit.

I watched a colleague front €40 of electricity a month for almost a year, because his company car arrived before the charger did. With no dedicated meter, his employer could not settle anything. Close to €450 out of his own pocket, never recovered.

What if I charge from an ordinary garage socket?

You lose the exemption. A standard domestic socket measures the whole house, not the car. The tax authority rejects this kind of "flat household" reimbursement, because nothing proves the car's real share. The only legal workaround is a separate meter on the dedicated circuit, but a proper charger is simpler and safer.

Who installs and owns the home charger?

Usually the company installs the home charger and keeps ownership during the contract. The installation itself is included in the car's BIK, with no surcharge. If the company transfers the charger to you at the end of the lease, that becomes a taxable benefit in kind, calculated on the residual value of the hardware.

Is the reimbursement really tax-free?

Yes, and it is now permanent. As long as the reimbursement stays below the CREG rate and appears in the car policy, it triggers no personal income tax and no social-security (ONSS) contribution. The driver remains taxed solely on the car's BIK.

This regime was long a temporary tolerance, renewed year by year, which worried fleet managers. FPS Finance circular 2025/C/38 made it permanent from Q3 2025: no more expiry date. That is a real difference for anyone signing a 48-month lease today, since the tax certainty now runs for the whole contract. The legal basis is articles 36 and 38 of the Income Tax Code, clarified by a series of circulars dated 2024 and 2025 (FPS Finance).

The trade-off is paperwork. The employer must keep charger readings and the detail of reimbursements, in principle for seven years, to defend the exemption at an audit. On the driver's side, you do nothing: the amount never appears on your return.

Why does the cap depend on your Region?

Because electricity does not cost the same everywhere in Belgium. The CREG rate reflects the average residential price actually paid in each Region, and Wallonia and Brussels are structurally more expensive than Flanders, mainly due to grid costs and regional surcharges.

This regional logic creates a useful disambiguation. If you live in Flanders, the Flemish rate applies, even if your employer is headquartered in Brussels. It is your charging address that counts, not the company's. For a fleet spread across the three Regions, payroll must therefore handle three different scales.

The employer can simplify by choosing one uniform rate for everyone. But that single rate cannot exceed the lowest of the three Regions, meaning Flanders in practice. As a result, a Walloon driver under a uniform rate is reimbursed at the Flemish cap, so less than what their Region would otherwise grant. It is worth checking which method your employer applies.

The concrete maths for 12,000 km a year

Take a realistic Belgian commuter case. A company car driving 12,000 km a year, charged 70% at home, at a real consumption of 17 kWh/100 km, is about 1,430 kWh charged at home over the year, or 119 kWh a month. The rest happens at work or on the motorway.

For this Walloon commuter, the reimbursement sits around €45 a month, roughly €540 over the year, fully exempt. A high-mileage driver at 200 kWh/month climbs past €900 a year. The gap between Regions stays modest at a single-driver scale, around €6 to €7 a month between Flanders and Wallonia, but it becomes real across a fleet of several dozen cars.

What if the employer does not reimburse home charging?

First, raise it before you sign. The reimbursement is not automatic: it depends on the car policy. If the policy is silent, the home-charged electricity stays on you, and for a driver who charges mostly at home that quickly means €400 to €700 a year out of pocket.

Three levers exist. Ask for a CREG-rate reimbursement clause to be added, which costs the employer nothing beyond the price of the electricity. Have the company install a smart charger, the technical condition for reimbursement. Or, failing that, shift part of your charging to the workplace and to public chargers covered by the charging card, which sit outside the regional cap.

The point to remember: home charging of a company car is designed to be neutral for your wallet. If it is not, the problem is not Belgian tax law, which is clear, but an incomplete car policy. And that is negotiable.
