The rapid rise in EV adoption brings a new set of practical challenges for companies. One of the most significant for fleet managers is how to accurately separate household electricity use from corporate EV charging costs when employees plug in at home.
Without a smart charging management platform, it’s impossible to tell which kilowatt-hours power the family fridge and which charge the company car.
Do these scenarios sound familiar to you?
Mixed use
Multiple EVs
Complicating matters further, strict regulations, such as Belgium’s strict tax rules, demand detailed and VAT-compliant invoices for every transaction. What seems like a simple home plug-in quickly becomes a heavy administrative burden for both companies and employees.
The answer is simple: Split billing offers the solution for your EV fleet. This applies whether you’re a freelancer with one car or run a business with a multi-car fleet.
What is Split Billing?
Split billing ensures company car charging at home is measured and reimbursed fairly. Instead of mixing EV charging with the rest of a household’s electricity bill, it creates a clear distinction between vehicle energy use (kWh) and household consumption.
This process is managed and automated by a charger management platform like Tap.
Here’s how it works: the smart home charger records exactly how much electricity the EV consumes. That consumption data is separated from the rest of the household load, and securely shared with the platform. The platform then generates an accurate report that bills the employer only for the energy used by the car, without accessing or affecting private household consumption.

Split billing provides a transparent, itemised view of energy use that builds trust and ensures everyone knows exactly what is being paid and why.
How Split billing works with Tap
Tap Electric provides a complete solution for both employers and drivers, covering charging at home, at work, and in public. The Tap EV management platform connects directly to the meter inside the charger, automatically handling calculation and the billing.
Tap’s split billing process:
Measure
When the employee plugs in at home, the smart station records exactly how much electricity the EV consumes.
Calculate
Based on the verified data, the platform determines the business-related portion of the energy consumption in accordance with local legislation.
Invoice
Tap automatically generates a VAT-compliant invoice for the employer, reflecting only the electricity used for business charging.
Reimburse
Tap reimburses the employee automatically and fairly, no receipts and no manual claims.
Win-win: How you can use Time-Of-Use tariffs to lower the costs of your EV Fleets
Split billing is not just about accurate accounting; it’s a powerful tool for cost optimisation.
Unmanaged charging is expensive: most drivers plug in their EVs as soon as they get home, between 17h and 20h, the most expensive time of the day.
A charger management platform like Tap Electric solves this by automatically shifting fleet charging to cheaper, off-peak hours using Time-of-Use (TOU) tariffs to lower costs.
By combining TOU tariffs with Tap’s split-billing platform, companies can automatically reimburse drivers at the real electricity rate, encourage off-peak charging, and cut both costs and emissions, all without increasing administrative workload.The result is a clear win-win: lower energy bills for employers, fair reimbursements for employees, and a greener fleet for everyone.
What Tap’s split billing solves
1
Transparent charging sessions
Every session starts with a unique Tap card or app account. That makes it easy to see whether it was the employee charging or someone else, like a partner.
2
Separation of business vs. private use
If the employee also uses the EV for personal trips, they can easily switch to their private Tap account and pay directly, both at home and on the go.
3
Clear, compliant invoices
Each month, Tap issues a tax-compliant invoice summarizing all charging activity. It comes with a detailed, downloadable report listing employees, locations, and consumption.
How does Tap help you stay tax compliant?
Tap Electric streamlines managing your EV fleet and simplifies compliance with complex Belgian tax legislation for your business.
Mandatory Reimbursement Tariffs (CREG): As of January 1, 2025, the Belgian government has established mandatory maximum tariffs for the reimbursement of home charging sessions. These tariffs are based on the quarterly rates of the CREG (Commission for the Regulation of Electricity and Gas) and vary by region.
With Tap’s split billing, you can set your tariffs for home reimbursement in the platform to automatically align with the quarterly changes in accordance with Belgian law. See Belgian Government document on maximum tariffs for more details.
- VAT on Charging:
- Home charging: In Belgium, the reimbursement of electricity consumed for charging a company car at home is generally exempt from VAT. This is because this is treated as an expense payment which the employee has already paid tax on towards their energy retailer. Tap Electric generates invoices that meet this requirement.
- The subscription fee for the split billing service: VAT is reverse charged for Belgian customers for this, since the subscription is for a service and Tap Electric is based in the Netherlands.
- Public charging: VAT is reverse charged for these transactions, per art. 51, § 2, 5 Belgian VAT Act. The is the sale of a good (electricity) and thus a domestic B2B transaction

Case Study: Check Car Sharing
Check is a leading Dutch shared mobility company focused on convenient and sustainable urban and regional travel. Unfortunately, like many parties in the e-mobility sector, Check saw a sudden spike in EV charging fraud in 2025. Because their charge card vendor had no anti-fraud technology in place, Check found themselves exposed. With our Tap’s Radar powered by AI, we were able to detect stolen cards and stop fraudulent transactions in real-time.
