California State Income Taxes in 2024: What Are They?

State income taxes are levied by the state government on income earned within that state. California state income taxes need to be paid by residents of California. Even non-residents of California are subject to California income taxes, if they make money in the state.

California uses a graduated-rate tax system, which means that the percentage of tax you owe increases as your income goes up. This makes it important to know which income tax bracket you fall under.

Let’s take a closer look at the California state income tax rates and who owes California state taxes in 2024.

Why Are California State Income Taxes Required?

You already pay federal taxes, why are state income taxes required as well in California? 

Each state has its own set of state income tax laws. The primary purpose of state income taxes is to raise revenue for the state government. California taxes are used to fund state-level programs, such as public schools, Medi-Cal, social services, and more.

Who Needs To Pay California State Income Tax?

So who exactly needs to pay California state income taxes? 

Typically, those who need to file a California income tax return are those who:

  • Received income from a California source
  • Earned income over a certain threshold
  • And are required to file a federal tax return

This criteria also includes three main categories of individuals: California residents, nonresidents, and part-year residents. 

Here is what gets taxed depending on your residency status:

  • Residents: All income from sources within California and outside of California
  • Nonresidents: Any income from California sources
  • Part-year residents: All income (sourced from within or outside California) while a California resident and all income from California sources while a non-resident

What Is My California Residency Status?

As you can see, your residency status plays a big role in determining your tax liability. Who is considered a resident? The Franchise Tax Board of California sets the residency rules.

You're a resident of California if you meet one of the following criteria:

  • You were physically present in California for more than a temporary or transitory purpose 
  • Your permanent home is located in California, even if you were temporarily elsewhere for a time

For example, someone visiting California for a week's vacation would not be considered a resident, since that is a temporary presence. 

And someone whose domicile is in California, but visits family in another state is still considered a California resident during the time they visit. 

You are considered a nonresident if you do not meet the definition of a California resident. 

A part-year resident is an individual who was a resident of California for part of the year, and a nonresident for another part of the year. 

What Are The California State Income Tax Brackets?

Knowing which tax bracket you fall under is important to know to anticipate how much you will owe in state income taxes. Tax rates typically change a little each year, so it’s important to stay up-to-date on the latest rates.

We’ve put together this California state income tax bracket table to help you better understand your tax liability.
