Beginning on July 1, 2014, manufacturers and certain research and developers, and beginning on January 1, 2018, certain electric power generators and distributors, may qualify for a partial exemption from sales and use tax on the purchase or lease of qualified machinery and equipment primarily used in manufacturing, research and development, and electric power generation or production, storage or distribution. To be eligible, they must meet all of these conditions:

  • Be primarily engaged in certain types of business, also known as being a “qualified person.”

The partial exemption is provided by Revenue and Taxation Code (RTC) section 6377.1.
