Wisconsin's New EV Charging Tax Explained | Simplify Compliance with ZEF Energy

How ZEF Can Help Wisconsin Commercial Charger Owners Navigate EV Charging Tax Requirements

The state of Wisconsin has implemented a tax on electricity dispensed at non-residential electric vehicle (EV) charging stations, requiring charger owners to remit $0.03 per kilowatt-hour to the state (WI DOR). For EV charging providers and businesses, this introduces a new layer of operational complexity. ZEF is here to help ensure compliance while minimizing the administrative burden.

Understanding the Requirements

Wisconsin’s tax applies to electricity dispensed by non-residential EV charging stations. This means that operators must:

  • Accurately track kilowatt-hour usage for all non-residential EV charging transactions.

  • Report this usage to the state.

  • Remit the collected tax payments on time.

Failure to comply with these requirements can result in penalties, making accurate tracking and reporting essential.

What does Non-Residential mean?

Non-residential means ANY chargers that are not used to charge in the home: therefore fleet, workplace, public etc. use-cases all apply, regardless of whether or not the driver has to pay for the charging session. It is only home charging that has a carve-out under the law.
