Workplace and company-car charging, billed correctly.

Since January 2026, the old monthly flat rates for charging company cars are no longer tax-free in Germany. Tax-free reimbursement is only possible on the basis of the actually charged kilowatt hours. POWR measures every charge at work and at the home wallbox and produces a consumption-exact, audit-proof statement.

Tax rule since January 2026

What changed in January 2026?

Since January 2026, the German tax authorities no longer accept monthly flat rates without consumption evidence as tax-free. Reimbursement is based on the actually charged amount of electricity, evidenced per charging session, at work and at the home wallbox.

Until the end of 2025, fixed monthly flat rates (15 to 70 euros) were a common, tax-accepted way to reimburse employees for charging a company car. With the current BMF circular, this simplification ends without a transition rule: a flat rate without evidence of the charged amount of electricity counts as a taxable benefit in kind since January 2026.

For valuing the evidenced kilowatt hours, employers have a choice: reimburse either the employee’s actual electricity price or an official average price per kilowatt hour (electricity price flat rate). The choice is exercised uniformly for the calendar year. In both variants the charged amount of electricity must be measured and documented per charging session, and that is exactly what POWR does.

As of July 2026. This section summarises the legal situation (current BMF circular) in general terms and does not replace tax advice. Please review your specific case with your tax advisor.

Consumption-based billing

How does POWR bill by consumption?

POWR records every charging session kWh-exact via the wallbox meter, assigns it to the charging person and their vehicle, and produces an audit-proof statement from it. Employer and tax office receive traceable evidence, without estimates and without monthly flat rates.

  1. Meter

    Every charging session is recorded to the exact kWh at the workplace and at the home wallbox and attributed to the person and the vehicle.

  2. Attribute

    POWR separates business from private charging and applies the correct electricity price for each charging location.

  3. Bill

    The recorded data becomes a monthly, consumption-accurate statement for the employer and an audit-proof record for the tax office.

At the workplace

How does charging at the workplace work?

On site, employees and company cars charge at your charging points and identify themselves with the POWR card or QR code. POWR attributes each session to the right person, so business and private use are cleanly separated and billed correctly.

  • Business and private charging are recorded and reported separately.
  • The same platform operates your charging points and delivers the billing.

At home (home charging)

How is home charging measured?

At the employee's private wallbox, POWR records every charging session to the exact kWh via the wallbox's meter. This separates the company car's consumption from private household electricity and lets it be reimbursed by consumption against the employer.

One platform

Operation, billing and charge card from a single source.

POWR does more than billing: the same platform controls your charging points over OCPP and issues the POWR card for Europe-wide roaming. That means you no longer have to manage separate point solutions.

Frequently asked questions

What changed in January 2026?
With the current BMF circular, the old monthly flat rates (15 to 70 euros) are no longer tax-free since January 2026. Tax-free reimbursement is based on the kilowatt hours evidenced per charging session, valued at the actual electricity price or the official electricity price flat rate. The employer exercises this choice uniformly per calendar year.
How is home charging measured?
POWR records every charging session at the home wallbox to the exact kWh via its meter and attributes it to the company car. This separates business charging from private household electricity, so it can be reimbursed by consumption against the employer.
What does the employer get, and what does the tax office get?
The employer receives a monthly, consumption-exact statement per employee and vehicle. For the tax office, POWR delivers audit-proof evidence of the charged kilowatt hours, regardless of whether the employer reimburses at the actual electricity price or the electricity price flat rate.
Which wallboxes are supported?
POWR is vendor-agnostic and connects wallboxes via the OCPP standard, at the workplace and at home. You are not tied to a particular hardware manufacturer and can keep using existing devices.
How is the electricity price determined?
The electricity price used can be stored per charging location: the site price at the workplace and the household-evidenced price at home. POWR then bills the metered kWh at that price and reports the basis transparently.
