Solar Sales Tax Exemption

Click to the bill report as passed during the 2019 legislative session. For more details visit the DoR’s 2019 Tax Legislation page and click on the “clean energy” link for details.

Federal Solar Investment Tax Credit.

Another important Washington state solar incentive is the solar Investment Tax Credit. The ITC is one of the most important federal policy mechanisms to support the growth of solar energy in the United States. Since the ITC was enacted in 2006, the U.S. solar industry has grown by more than 10,000% – creating hundreds of thousands of jobs and investing billions of dollars in the U.S. economy in the process.

Unfortunately, In December 2019, Congress and the White House were unable to agree on including an extension of the solar Investment Tax Credit (ITC) in an end of year tax package meaning the credit will decrease over the next two years and disappear completely in 2022.

As it stands the ITC is scheduled to step down as follows:

  • 26% tax credit for projects that begin construction in 2020
  • 22% tax credit for projects that begin construction in 2021
  • 2022 the ITC no longer exists for residential systems.

Net Metering

When your solar PV system produces more power than you’re using, net metering allows the excess electricity to spin your meter backwards, giving you a dollar-for-dollar utility credit for all the excess energy. This Washington state solar incentive basically makes your electric utility your energy bank. A bi-directional meter replaces your existing electricity to track your energy usage and production. This allows you to use your stored energy credits at times when the sun isn’t shining as much, such as nighttime and winter.
