Idle Reduction Tax Incentives and Exemptions

Tax incentives are available for the infrastructure and services that support the use of auxiliary power for vehicles with gross vehicle weight ratings of more than 14,000 pounds through on-board or stand-alone electrification systems. These incentives include a business and occupation tax deduction and a sales and tax exemption for machinery and equipment used to provide auxiliary power at truck stops. Sales and use tax exemptions are also available for any parts and labor necessary to enable heavy-duty diesel trucks to accept power for on-board electrification systems. These exemptions expire July 1, 2015. (Reference Revised Code of Washington 82.04.4338, 82.08.815, 82.08.825, 82.12.815, and 82.12.825)
