[to be written-up June-July2021] Note, the CA state discourse is inconsistent re the naming of its bodies: we have “California State Board of Equalization”, with the same phrase given as the copyright holder (https://www.boe.ca.gov/), whereas there’s “State of California Franchise Tax Board”, with the copyright holder as “California Franchise Tax Board” (https://www.ftb.ca.gov/). For simplicity, this blog gives them both as ‘California State’.
