State law prohibits tax officials from disclosing the identity of corporations that do not pay taxes
in California. Studies based on corporate annual reports and securities filings have identified
publicly traded corporations that pay no federal income taxes.
Since corporations are not required to disclose where they pay state corporate taxes and how much they pay, it is not possible to use this information to identify corporations that pay no California corporate income taxes.
California-based corporations that paid no federal income taxes between 2001 and 2003
include Walt Disney, Fluor, Health Net, Ingram Micro, and Computer Sciences.3
Computer Sciences reported US profits of $1.29 billion and received $31 million in federal tax rebates during the three year period studied. Ingram Micro received tax rebates in two of the three
years.
What About the Alternative Minimum Tax?
The AMT was designed to ensure that profitable businesses paid at least a minimum level of tax on their income. However, over time, the goal of the AMT has been undermined as lawmakers allowed certain preferences to reduce the amount corporations would pay under the AMT.
Preferences that enable corporations to reduce what it would owe under the AMT include the Research and Development Tax Credit; Low-Income Housing Tax Credit; various Enterprise Zone, Local Agency Military Base Recovery Area (LAMBRA), and targeted tax area credits; and Natural Heritage Preservation Tax Credit.
