California's sales and use tax is dedicated to various state and local purposes.
In recent decades, Californians have spent more of their income on housing, health care, and other services not subject to the state and local sales tax.
Over the past several decades, the personal income tax has replaced the sales tax as the main source of the state's General Fund revenue.
Last week, data showed that personal and corporate income taxes together were $1.6 billion above June 2014 budget projections through November 30. New preliminary data on November General Fund sales tax collections indicate this tax is running a couple of hundred million dollars below budget act projections for the 2014-15 fiscal year to date.
