Let’s be real for a second. Looking at a tax table is about as exciting as watching paint dry in a humidity chamber. But if you live in California, ignoring the ca state tax brackets 2024 is a dangerous game that usually ends with a surprise bill from the Franchise Tax Board (FTB) that could ruin your whole week.
California has a reputation for being the "high tax state," and honestly, it’s not just a rumor. With a top marginal rate that hits 13.3%—and effectively 14.4% for high earners this year—it’s a complex beast.
But here’s the kicker: most people think they’re paying way more than they actually are because they don't understand how progressive brackets work. You aren't taxed at your highest rate on all your money. It’s a ladder. You pay a tiny bit on the first chunk, a little more on the next, and so on.
The 2024 Numbers You Actually Need
For the 2024 tax year (the returns we're all sweating over in early 2025), the FTB adjusted the brackets by 3.3% to keep up with inflation. It’s a small mercy, but it prevents "bracket creep," where you end up in a higher tax tier just because your boss gave you a cost-of-living raise that didn't actually make you "richer."
If you’re filing as Single or Married Filing Separately, your first $10,756 of taxable income is only hit with a 1% rate. That’s basically pocket change in the eyes of the state. Once you cross that, the 2% bracket kicks in for everything up to $25,499.
The jumps happen fast. By the time you’re making over $70,606 as a single person, you’ve landed in the 9.3% bracket. This is where the "California tax bite" starts to feel real for the middle class.
For Married Filing Jointly, the numbers basically double. You don't hit that 9.3% wall until your combined taxable income clears $141,212.
Why 13.3% Isn't the Whole Story Anymore
You’ve probably heard the "13.3%" figure tossed around at dinner parties or on news segments about people fleeing to Texas. That’s the 12.3% top bracket plus a 1% surcharge for the Mental Health Services Act.
But 2024 brought a massive change that many high-earners missed.

Starting January 1, 2024, the state lifted the "wage ceiling" on State Disability Insurance (SDI) contributions. Previously, you stopped paying that 1.1% tax once you earned over a certain amount (about $153k). Now? There is no limit. If you’re a high-income professional making $1 million, that extra 1.1% applies to every dollar of your wages.
Effectively, the top "all-in" rate for wage earners in California is now 14.4%.
The Standard Deduction: Your First Line of Defense
Before you even look at those brackets, you get to chop a chunk off your income. For 2024, the California standard deduction is:
- $5,540 for Single filers or Married filing separately.
- $11,080 for Married filing jointly, Head of Household, or Surviving Spouses.
Is it lower than the federal deduction? Yes, significantly. But California also gives you a "Personal Exemption Credit," which is $149 for individuals. It’s a direct dollar-for-dollar reduction of your tax bill, not just a deduction from your income.
Common Mistakes: Taxable Income vs. Gross Income
I see this all the time. Someone says, "I make $100k, so I’m in the 9.3% bracket."
Sorta, but not really.
Your tax bracket is based on taxable income, not your gross salary. After you take out your 401(k) contributions, your health insurance premiums, and either your standard or itemized deductions, that $100k might look more like $75k.
Also, remember that California doesn't play nice with certain federal rules. For example, if you're lucky enough to have an HSA (Health Savings Account), the feds let you deduct those contributions. California? Nope. They treat that money as taxable income. It’s one of those "California additions" that catches people off guard.
The "Hidden" 1% Mental Health Tax
If you happen to be having a very good year and your taxable income clears $1,000,000, you get hit with an extra 1%. This isn't just a high-income bracket; it's a specific surcharge. It’s stayed at $1 million for years, even though inflation has changed what $1 million buys in San Francisco or LA.
The Million-Dollar Net Operating Loss (NOL) Trap
For business owners, 2024 is a weird year. The state suspended the Net Operating Loss (NOL) deduction for 2024 through 2026 for those with income over $1 million.
If your business had a rough couple of years and you were hoping to use those losses to offset a big 2024 gain, you might be out of luck if your income is high. You can still carry the losses forward, but you can't use them right now to lower your 2024 bill.
Actionable Steps for Your 2024 Return
Don't just hand a pile of receipts to your CPA and pray.
First, check your withholding. If you haven't updated your DE 4 (the California version of the W-4) in years, you’re likely under-withholding, especially with the new SDI rules.
Second, look into the Pass-Through Entity (PTE) Elective Tax. If you own an S-Corp or an LLC, this is the single best way to circumvent the $10,000 federal limit on State and Local Tax (SALT) deductions. It’s a "workaround" that the IRS actually blessed, and it can save California business owners tens of thousands of dollars.
Finally, track your California-specific adjustments. Since the state doesn't follow federal law on things like student loan interest or certain depreciation rules, keeping a clean list of "California-only" expenses is the only way to ensure you aren't overpaying the FTB.

Check your 2024 income against the adjusted $10,756 (Single) or $21,512 (Joint) base tiers to see where your "true" starting point is. If you're hovering right on the edge of a higher bracket, a last-minute contribution to a traditional IRA (if you qualify) or a business expense could drop you back down and save you a percentage point or two across your top earnings.
