California state finances are the budget of the U.S. state of California. They are made up of several funds derived from taxes.  The General Fund makes up 3/4th of the entire budget; it allocates monies to state operations and payments to localities.  The annual budget is proposed by the California State Legislature and approved by the Governor of California, who enjoys the prerogative of line-item veto. 
California levies a 9.3 percent maximum variable rate income tax, with six tax brackets, collecting about $40 billion per year (representing approximately 51% of General Fund revenue and 40% of tax revenue overall in FY2007).  California has a state sales tax of 8.25%, which can total up to 10.75% with local sales tax included.  All real property is taxable annually, the tax based on the property's fair market value at the time of purchase or completion of new construction. Property tax increases are capped at 2% per year (see Proposition 13).
One notable side effect of California's tax structure is that a substantial portion of the state's income comes from a small proportion of wealthy citizens. For example, it is estimated that in 2004 the richest 3% of state taxpayers (those with tax returns showing over $200,000 in yearly income) paid approximately 60% of state income taxes. 
State spending increased from $56 billion in 1998 to $131 billion in 2008, and the state was facing a budget deficit of $40 billion in 2008.  California is facing another budget gap for 2010,  with $72 billion in debt.  California faces a massive and still-growing debt. 
[ needs update] In June 2009 Gov. Arnold Schwarzenegger said "Our wallet is empty, our bank is closed and our credit is dried up."  He called for massive budget cuts of $24 billion, about 1⁄4 of the state's budget.  
California faced a $26.3 billion budget deficit for the 2009–2010 budget year.  While the legislative bodies appeared to address the problem in 2008 with the three-month delayed passage of a budget they in fact only postponed the deficit to 2009 and due to the late 2008 decline in the economy and the credit crisis the problem became urgent in November 2008.
2012 brought somewhat of an improvement to state finances, though the state still faced a $16 billion budget deficit for the year. To help alleviate this, Governor Jerry Brown introduced proposals to bring measures to voters, in order to pass tax increases. If these are not passed, more severe cuts are expected. California's unemployment rate also fell, from a high above 12.4%, to below 11%, currently standing at around 10.7%. 
In 2017 a miscalculation of the costs for the state's Medi-Cal program of $1.9 billion in 2016 led Governor Jerry Brown to project the state of California will face a $1.6 billion budget deficit. 
California uses two kinds of tax anticipation notes: Revenue Anticipation Notes (RANS), which are issued and paid back within a fiscal year, and Revenue Anticipation Warrants (RAWS), which are issued on a fiscal year and paid back the following fiscal year.  RANS are commonly used due to the delay between expenditure and tax collection while RAWS are only used in times of crisis.
