Alternative Fuel Vehicles and Plug-In Hybrids Washington State Tax Exemptions

On August 1, 2019, Washington State reinstated the sales and use tax exemption for the sales of:

  • Vehicles powered by a clean alternative fuel.
  • Certain plug-in hybrids.

The exemption applies to dealer and private sales of new, used, and leased vehicles sold on or after August 1, 2019.

  • New vehicle transactions must not exceed $45,000 in purchase price or lease payments.
  • Used vehicles transactions must not exceed $30,000 in fair market value or lease payments.

These thresholds may also include the value of your trade-in, if applicable.


If the cost of a new vehicle is $48,000, and the value of your trade-in is worth $6,000, you can't receive the tax exemption. Even though the trade-in brought the cost down to $42,000, the new vehicle was still worth over the $45,000 limit. You cannot use a trade-in to lower the price of a vehicle to meet the exemption limits.
