Bay Area venture capitalist Tom Steyer has poured millions of dollars into this measure. He says it would raise $1 billion a year for green building projects and the state budget by closing a tax loophole.
Steyer: "There is an error in state tax law that allows out-of-state corporations to pay less tax than California corporations on the same sales."
Peter DeMarco represents a business coalition that believes the tax law should remain as it is.
DeMarco: "Now is hardly the time - if ever - to make some policy change that is going to drive workers and jobs out of California."
Two other tax measures could also be on the November ballot - one from education advocate Molly Munger and one from Governor Jerry Brown. There's also a proposal that would end the same tax exemption in the California legislature.
