Quick Answer
California sales tax on labor depends on four distinctions: (1) labor to create / fabricate / produce TPP — taxable; (2) installation labor — generally exempt; (3) repair labor — generally exempt if separately stated; and (4) services to property — facts-specific analysis. The short version is that fabrication labor is taxable but installation and repair labor generally aren’t. In our experience, the separately-stated requirement is where most contractors and repair shops get tripped up in audits.1
