Does California Have an Income Tax?

The state’s income tax rates are progressive, meaning higher income levels are taxed at higher rates. California has one of the highest income tax rates in the nation, with rates ranging from 1% to 13.3%.

- High-Tax State: With a top marginal rate of 13.3%, California’s income tax is the highest in the U.S.
- No State Income Tax States: States like Texas, Florida, and Nevada do not levy personal income taxes.
- Middle-Tier States: Many states have a flat or progressive tax system with lower top marginal rates compared to California.
For high-income earners, understanding California’s aggressive tax structure is essential to minimize liabilities and take advantage of available tax-saving opportunities.
