                     INFORMATION UPDATE

Assembly Bill (AB) 398 (Chapter 135, Stats. 2017) and AB 131 (Chapter 252, Stats. 2017) amended Revenue and Taxation 
Code (R&TC) section 6377.1, which provides for a partial sales and use tax exemption for certain manufacturing and research & 
development equipment. Among other changes, the amendments change, beginning January 1, 2018:
• The definition of a “qualified person” to include persons primarily engaged in electric power generation or distribution of electric 
power as described in NAICS codes 221111 to 221118, or 221122.
•   The definition of “qualified tangible personal property” to include special purpose buildings and foundations used as an integral part 
of the generation or production, or storage and distribution, of electric power.
The exemption certificate forms, CDTFA-230-M, Partial Exemption Certificate for Manufacturing and Research & Development 
Equipment, and CDTFA-230-MC, Construction Contracts-Partial Exemption Certificate for Manufacturing, and Research & 
Development Equipment, are included in  Regulation 1525.4, Manufacturing and Research & Development Equipment. We have 
revised the date on the posted exemption certificate forms to conform with the statutory changes. These forms will be further revised 
once the process of updating Regulation 1525.4 is completed.  
We suggest that, if applicable, the person issuing the exemption certificate add a statement on the certificate that they are “primarily 
engaged in the generation or production, or storage and distribution, of electric power as described in NAICS codes 221111 to 221118, 
or 221122.” 
For more information about the amendments to R&TC section 6377.1, please see our online guide, Tax Guide for Manufacturing and 
Research & Development Equipment Exemption.
