California's income tax system differs from the federal tax system in a few ways. Many federal deductions are limited or not allowed in California, but the Golden State does have some of its own deductions and credits that you might benefit from.

Key Takeaways

  • California’s standard deductions are less than half of what they are at the federal level.
  • The state’s child and dependent care credit is a fixed percentage of the federal credit.
  • California imposes a 1% surcharge on very high incomes. Taxpayers who are subject to it pay a tax rate of 13.3% on their top dollars.

Income That's Exempt From California Tax

Certain types of income are exempt from tax in California, although they're taxable on your federal return. These income sources include:

  • Social Security and railroad retirement benefits that aren't included in your federal adjusted gross income, but not other private, state, local, or federal pensions
  • Interest earned on federal savings bonds
  • State income tax refunds
  • Distributions from health savings accounts (HSAs)
  • Unemployment compensation
  • California state lottery winnings

Taxable Income in California

The flip side is that you'll have to pay taxes in California on some types of income that aren't taxed at the federal level, such as foreign earned income that you can exclude on your federal tax return. In addition, interest earned on municipal, state, and local bonds from outside California is also taxable.

Alimony you receive is taxable income in California, although it's no longer taxable at the federal level for divorces entered into after 2018. The spouse paying alimony or spousal support is entitled to a tax deduction for that amount.

California Itemized Deductions

California doesn't allow deductions for some things the federal government allows, such as contributions to HSAs, adoption expenses, educator expenses, qualified higher education expenses, and paid state, local, or foreign income taxes. The amounts of other deductions the federal government allows, such as IRA contributions and charitable giving, are also limited in California.

But California has some deductions of its own:

  • Interest on loans from utility companies is deductible when the loan is used to purchase and install energy-efficient equipment or products.
  • The limit on mortgage indebtedness for the home mortgage interest deduction is $1 million in California as of the 2022 tax year, the return you file in 2023. The federal limit is $750,000.

The California Standard Deduction

The California standard deduction is much less than what's offered by the IRS. As of the 2022 tax year—the return you file in 2023—the state-level standard deductions are:

  • $5,202 for single taxpayers, as well as married and registered domestic partner (RDP) taxpayers who file separate returns
  • $10,404 for married and RDP taxpayers who file jointly, as well as heads of household and qualifying widow(er)s


The 2022 standard deductions at the federal level are $12,950 for single taxpayers and married taxpayers filing separately, $19,400 for heads of household, and $25,500 for married taxpayers filing jointly and qualifying widow(er)s.

California Tax Credits

Tax credits are deducted from any tax you owe the government. This makes them more advantageous than deductions, which only reduce the income on which you're taxed. Some of California's income tax credits include:

  • Renters Credit: This is a $60 credit for single renters whose annual incomes fall below $43,533 as of 2022. It increases to $120 for married/RDP taxpayers who file jointly and whose annual incomes fall below $87,066. The credit is nonrefundable. You must pay rent in the state of California for half the year or more.
  • Child and Dependent Care Credit: A percentage of the federal credit is allowed for qualified child and dependent care expenses. This credit is refundable. Its rules largely mirror those for the federal Child and Dependent Care Credit.
  • Joint Custody Head of Household Credit: Taxpayers who are single and married/registered domestic partners who file separately and have a child can qualify for this credit worth up to $556 for the 2022 tax year.

California Tax Rates

California income tax rates vary a bit from year to year. They're levied on California residents’ income and non-residents’ income from California sources.


California also charges a mental health services surcharge tax of 1% on incomes over $1 million, over and above the regular tax rate for residents and certain non-residents with incomes over that threshold. The tax helps to fund the state's behavioral health system.

The state has nine tax brackets as of the 2022 tax year. California's top individual income tax rate is 12.3% on annual incomes over $677,275 for single taxpayers and married or registered domestic partner (RDP) taxpayers who file separate returns. The 12.3% threshold for married and RDP partners filing jointly is $1,354,550 and $921,095 for head of household filers.

The lowest rate is 1% on annual incomes of up to $10,099 for single filers, $20,198 for married and RDP filers, and $20,212 for head of household filers for the tax year 2022.

Filing Your Return

You can find all of the forms you'll need to file your tax return on the California Franchise Tax Board (FTB) website. The FTB lists free web-based tax preparation services on its website as well. Those who meet eligibility criteria can use CalFile, the state’s free online return-preparation tool.
