What is California State Income Tax?
The Franchise Tax Board imposes California state income tax on individuals and businesses that earn income in the state. This applies not only to residents but also to people who are not residents of the state but work and earn income from the state’s sources. The system is progressive, which means if your income increases, the tax rate on that income will also increase.
This also means that people with high incomes pay higher income tax than low-income earners. California’s tax system differs from other states’ because it does not offer a flat tax rate, making tax planning more important.

Key Rate Insights:
- 1 percent applies to the lowest income bracket
- Rates gradually increase across multiple brackets
- The top rate of 13.3 percent applies to high-income individuals

It is important to note that California does not have separate tax rates for different income types, such as capital gains. All income is generally taxed at the same rate.
Understanding California Tax Brackets
In California, there are tax brackets that determine how your income is taxed in layers. Here, your entire income is not taxed at a single rate; it is divided into separate portions, each taxed at a specific rate.
How it Works
If you move into a higher tax bracket, then only the income within that bracket is taxed at the higher rate. The rest of your income remains taxed at lower rates.
Filing Status Categories:
- Single
- Married filing jointly
- Married filing separately
- Head of household
Each category has different income thresholds, which means your filing status can significantly impact your tax bill.
What Income is Taxable in California?
California taxes nearly all forms of income, making it one of the broadest tax systems in the United States.
Common Taxable Income Includes:
- Salaries and wages
- Self-employment and freelance income
- Rental income
- Capital gains from investments
- Bonuses, commissions, and tips
If you are a California resident, you are taxed on your worldwide income. Non-residents, however, are taxed only on income earned in California.
Standard Deduction vs Itemized Deductions
When filing taxes, you have the option to reduce your taxable income through deductions. You can either take the standard deduction or itemize your deductions.
1. Standard Deduction
This is a fixed amount that reduces your taxable income and is easier to claim.
2. Itemized Deductions
These include specific expenses such as:
- Mortgage interest
- Medical expenses
- Charitable donations
For many taxpayers, especially high-income individuals and homeowners, itemizing deductions can yield greater tax savings.
California Tax Credits You Should Know
You must know about tax credits that help you reduce the amount of tax you owe. These tax credits are more valuable than tax deductions.
Popular California Tax Credits:
- California Earned Income Tax Credit (CalEITC)
- Young Child Tax Credit
- Child and Dependent Care Credit
Most tax credits are designed for low- and middle-income households, but eligibility depends on income and other criteria.
