This is an interesting case because it is another example of how Kal-E-forn-YA taxes everything. It's too long to post here. So, if you're interested, read it at FindLaw.com.
Summary: In 1989, California enacted legislation that imposed a tax on businesses (with 50 or more employees that "use, generate, store, or conduct activities in this state related to hazardous materials."
It should come as no surprise that the California Board of Equalization has decided that fluorescent lightbulbs, batteries, inks, correction fluid, and toner used in printers and fax machines constitute "hazardous materials"! Thus, all businesses with 50 or more employees have to pay the "Hazardous Materials Tax".
I did not make this up!
