Frequently Asked California Tax Questions
What is the California Standard Deduction for 2026?
For the 2026 tax year, the California standard deduction is $5,900 for single filers and $11,800 for married couples filing jointly (or Head of Household). These amounts are indexed annually for inflation by the California Franchise Tax Board (FTB). Unlike the federal standard deduction, California's is significantly smaller, meaning more of your income is subject to state tax.
Does California tax income over $1 million?
Yes. California imposes a 1% Mental Health Services Tax surcharge on all taxable income that exceeds $1,000,000. This applies regardless of filing status and brings the top marginal rate to 13.3% — the highest state income tax rate in the United States. The surcharge was enacted through Proposition 63 in 2004 to fund mental health services statewide.
