Wind Energy Production Tax

The owner of a WECS that converts wind to usable form of energy must file a Wind Energy Production report. 

Filing

The owner of a WECS must file the Wind Energy Production report online through our e-Services system. See filing details in the Wind Energy Production Report Instructions. 

The owner of a WECS must register for an Energy Production Account before filing. Register by calling Business Registration at 651-282-5225.

Report Deadline

The Wind Energy Production Tax report is due annually on January 15. 

An extension of up to 15 days may be granted if the owner submits a written request showing good cause. For more information, visit the extensions request instructions webpage. 

If the owner of a WECS does not file on time, we will determine the tax by applying a production rate of 60% to the nameplate capacity of the system. 

The department will determine the tax due and notify the owner of the WECS and the counties where the systems are located by February 28. 

Counties bill and collect the wind energy production tax. The counties where the systems are located will send the tax bills. The tax must be paid to the appropriate county treasurer by May 15. 

The department has an optional Energy Production Tax Statement that counties can use for billing the Solar or Wind Energy Production Taxes.

The amount of tax is paid to the county treasurer at the time and manner provided for payment of property taxes. Taxes are considered personal property taxes. 

Revenues from wind energy production taxes are part of the settlement between the county auditor and county treasurer. Revenue is distributed as 80% to the county and 20% to the city/township where the systems are located. 

The nameplate capacities of WECS under common ownership will be combined if the system meet both criteria:

• Located within five miles of each other
• Constructed in the same 12 month period

Common ownership exists when the same, or similar, persons or entities own two or more systems, even if the ownership shares are different for each system. Common ownership does not exist solely because the same person or entity provided equity financing. 

The original date of an existing wind energy conversion system is not changed if the system is replaced, repaired, or otherwise maintained or altered. 

In the case of a disagreement with the department of revenue on the combined nameplate capacity of the system, the department of commerce shall determine the total size of the system. 

If approved by the county where the system is located, the land that the WECS is located on is valued in the same manner as similar land that has not been improved with a WECS.

The land is classified as the most probable use if it were not improved with a WECS.
