A YES vote on this measure means: Three business tax provisions will return to what they were before 2008 and 2009 law changes. As a result: (1) a business will be less able to deduct losses in one year against income in other years, (2) a multistate business will have its California income determined by a calculation using three factors, and (3) a business will not be able to share tax credits with related businesses. A NO vote on this measure means: Three business tax provisions that were recently changed will not be affected. As a result of maintaining current law: (1) a business will be able to deduct losses in one year against income in more situations, (2) most multistate businesses could choose to have their California income determined based only on a single sales factor, and (3) a business will be able to share its tax credits with related businesses.
