California Code, Revenue and Taxation Code - RTC § 6010.7

Paragraph (5) of subdivision (g) of Section 6006, paragraph (5) of subdivision (e) of Section 6010, and Section 6094.1 shall have no application to a lease of a chemical toilet unit. Such a lease is a “sale” and “purchase” and the taxes imposed by this part apply measured by the lease or rental price accordingly, regardless of whether the unit is leased in substantially the same form as acquired and regardless of whether sales tax or use tax has been paid with respect to the chemical toilets at the time of their acquisition.
