    New WA Sales Tax Exemption on Solar Panels

    Washington State just made solar energy installations cheaper. Beginning July 1st, 2019, all equipment for solar energy systems smaller than 100 kilowatts in size are exempt from 100 percent of state and local sales and use tax.

    This saves thousands on most projects. For an average-sized residential system, this will save homeowners $2,500+ on the total project cost. That’s about 8% savings!

    This new Washington state tax exemption for solar (PDF) is good through December 2029. Paired with the last year of a federal solar tax credit that returns 30% of the system cost, solar technology is better (and cheaper) than ever. Now is a great time to start making your own power!

    How Does It Work?

    Simple! Instead of paying the typical sales tax you normally would, you now do not. This tax exemption alone significantly decreases the price by thousands. Depending on which city you live in determines how much you will save. If you live in Vancouver, Washington you will pay 8.4% less than you would have prior to July 1st, 2019. Below is a list of SW Washington cities and their current combined state and local sales tax.
