Living in the Golden State is beautiful, but man, the taxes are a lot. If you’ve ever looked at your paycheck and wondered why such a huge chunk is missing, you’re looking at one of the most progressive tax systems in the country. California doesn't just have one rate. It has nine. Well, technically ten if you count the millionaire’s surtax.
Basically, the california 2024 tax brackets work like a ladder. You don't pay the highest rate on every dollar you make. You only pay the higher rates on the money that "lands" in those specific buckets. People get this wrong all the time. They think if they get a raise and hit a higher bracket, they might actually take home less money. That’s a myth. Your first $10,000 is always taxed at the lowest rate, regardless of whether you're a barista or a tech CEO.
How the 2024 Brackets Actually Shake Out
The Franchise Tax Board (FTB) adjusts these numbers every year for inflation. For 2024, they bumped things up by 3.3% because, honestly, everything is more expensive now.

If you're filing as Single or Married Filing Separately, the 1% rate applies to your first $10,756 of taxable income. Once you go over that, the 2% bracket kicks in for the next chunk of change up to $25,499. It keeps climbing from there: 4%, 6%, 8%, and then a big jump to 9.3% for income over $70,606.
For those Married Filing Jointly, the buckets are exactly double. You’ll pay 1% on your first $21,512. The top rate of 12.3% doesn't even touch you until your joint taxable income clears $1,442,628.
The Mental Health Surcharge
There is a "secret" bracket. If your taxable income goes over $1 million, California tacks on an extra 1% for the Mental Health Services Act. This was established by Proposition 63. It means the real top rate for the state's highest earners is 13.3%.
The Standard Deduction: Your First Win
Before you even look at those brackets, you get to shave some money off the top. This is the standard deduction. For the 2024 tax year, it’s $5,540 for single filers. If you’re married filing jointly or a head of household, that number jumps to $11,080.

Most people just take the standard amount. However, if you have a massive mortgage or huge medical bills, you might want to itemize. California's rules for itemized deductions are kinda specific and don't always match the federal rules, so watch out for that.
A Big Change Nobody Is Talking About: SDI
There’s a massive change for 2024 that isn't technically an "income tax" but hits your wallet the same way. It’s the State Disability Insurance (SDI) tax. In 2023, there was a cap on how much of your salary was subject to this 1.1% tax.
Starting January 1, 2024, that cap is gone.
If you make $500,000, you’re now paying 1.1% on the whole thing. For high earners, this is a sneaky tax hike of several thousand dollars that caught a lot of people off guard when their first January paychecks arrived.
Why Your "Taxable Income" Isn't Your Salary
Keep in mind that the california 2024 tax brackets apply to taxable income, not your gross salary. You subtract your 401(k) contributions, your health insurance premiums, and your deductions first.
- Gross Pay: $100,000
- 401(k) Contribution: $20,000
- Standard Deduction: $5,540
- Taxable Income: $74,460
In this example, only that $74,460 gets put through the bracket "machine."
Credits That Actually Help
California offers a few credits that act like a gift card for your taxes. A credit is better than a deduction because it lowers your tax bill dollar-for-dollar.
- California Earned Income Tax Credit (CalEITC): If you earn less than $30,950, you could get up to $3,644 back.
- Young Child Tax Credit: This provides up to $1,117 for qualifying families with kids under 6.
- Renter’s Credit: It’s small—$60 for singles or $120 for couples—but if you make under $52,421 (single) or $104,842 (joint), it’s basically a free dinner.
Planning Your Next Move
Tax season in California is always a headache, but knowing the numbers helps you plan. Since the state relies so heavily on high-income earners, the brackets are steep.
If you want to lower your bill for the 2024 tax year:
- Max out your 401(k) or 403(b): This is the easiest way to drop into a lower bracket.
- Check your withholding: If you got a big bonus or a raise, use the FTB's online calculator to make sure you aren't going to owe a massive penalty in April.
- Keep receipts for the Renter's Credit: If you're eligible, it's an easy win that most people forget to claim.
The best thing you can do right now is pull your most recent pay stub. Look at the "Year to Date" California tax withheld. Compare it to where your income sits in the brackets above. If you're falling behind, adjust your DE 4 form with your employer now so you don't get hit with a surprise bill later.
