Sales and use tax refunds and deferrals are available for certain clean energy projects when certified by the Department of Labor & Industries (L&I). This program was created as a way for the state to address the impacts of climate change on a large scale.

NOTE: If you are a homeowner adding solar panels to your residence, you do not need to read further. Please go to the state Department of Revenue (DOR) website for additional information.

To receive a refund, a project developer must comply with specific labor standards. The machinery and equipment generating the electricity must be installed and completed by Dec. 31, 2029.

The amount of the refund depends on the generating capacity of the project. Projects that can receive the refund must be of the following types:

  • Solar.
  • Fuel cells.
  • Wind.
  • Biomass energy.
  • Geothermal resource.
  • Tidal or wave energy.
  • Technology that converts otherwise lost energy from exhaust.

The labor standards L&I will use to certify a project can be included in a Project Labor Agreement (PLA) or Community Workforce Agreement (CWA) as part of the project. A project without a PLA or CWA must still fulfill the specific labor standards.

You’ll need to submit an application to L&I to receive a certification for your project. Take the certification to DOR to receive a refund for the purchase of the energy generating machinery and equipment.

Deferrals

To receive a deferral, a project developer must comply with specific labor standards described below. Applications must be received by June 30, 2032. Projects must be completed by Jan. 1, 2033.

Qualified projects must meet the standards in one of these categories:

  • Clean technology manufacturing, clean alternative fuels production, and renewable clean energy storage (projects must be at least $2 million).
  • Solar canopies on large-scale commercial parking lots and other similar areas (must produce at least 1 MW of energy).

The labor standards L&I will use to certify a project can be included in a Project Labor Agreement (PLA) or Community Workforce Agreement (CWA). A project without a PLA or CWA must still fulfill the labor standards, described below.

In the application to L&I, you will need to decide one of three tax deferral amounts sought:

  • 100% - If your project has a PLA or CWA. You will need to include the agreement in your application.
