The "stroometiket" is published according to the guidelines of the Autoriteit Consument & Markt (ACM). To prove the source of the electricity supplied, energy suppliers use the system of Guarantees of Origin (green) and Certificates of Origin (grey) which follows from the Elektriciteitswet 1998. Axpo redeems the Guarantees of Origin or Certificates of Origin on the Dutch certificates register Verticer.

Energy Tax Declarations (Energiebelasting)

Could your company qualify for a lower energy-tax rate or an exemption?

Energy tax (energiebelasting) is charged on the electricity and natural gas supplied to your company. In specific situations, a different rate or an exemption may apply. To allow Axpo to assess and, where applicable, apply the correct treatment, please submit the declaration that matches your situation before delivery starts or as early as possible.

Important: This overview is a practical guide, not tax advice. Eligibility depends on the statutory conditions and your specific situation. Please notify Axpo promptly if your circumstances change.

Electricity declarations

Your situation

Declaration and what it does

When to act

You re-supply electricity to third
parties, for example via a closed
distribution system.

Resupply / onward supply declaration (Verklaring doorlevering).
This may allow electricity that is passed on to be supplied without
energy tax at this stage, provided the relevant parties account for
energy tax themselves.

Submit before the
relevant supply starts.
Usually submitted once;
tell Axpo if the situation
changes.

Your business use exceeds 10 million
kWh per year.

Business electricity-use declaration (Verklaring zakelijk verbruik
elektriciteit). This enables the business-use tax rate for qualifying
consumption.

Submit as soon as possible.
It is generally valid
indefinitely, subject
to continuing eligibility.

You have multiple electricity and/or
gas meters at the same location.

WOZ-object / cumulation declaration (Verklaring WOZ-object).
It supports the correct aggregation of consumption across qualifying
connections at one location, which may affect the tax brackets and
the energy-tax reduction.

Contact Axpo early.
Supporting documentation
may be required.

The electricity connection supplies a
property where people can stay,
such as an office or home.

Residence-function declaration (Verklaring verblijfsfunctie). This

and notify us of changes.

chemische reductie, elektrolytische en metallurgische procedés).

Your situation

Declaration and what it does

When to act
