You probably already know that California has some of the highest income taxes in the country. It’s basically a meme at this point. But if you’re living in the Golden State, or thinking about moving here, you need to look past the "13.3%" headline number everyone screams about on social media. That's the top rate. Most people don't pay that.
For the 2025 tax year—the taxes you’ll actually file in early 2026—the California 2025 tax brackets have been adjusted for inflation. This is a big deal because it helps prevent "bracket creep." That’s the annoying phenomenon where you get a cost-of-living raise, but it gets eaten alive because it pushes you into a higher tax percentage. The Franchise Tax Board (FTB) tweaks these numbers annually based on the California Consumer Price Index.
Honest truth? It’s a progressive system. It’s designed to hit the highest earners hard while giving lower-income folks a bit of a breather. But because California is, well, expensive, those "high" brackets often start hitting people who feel firmly middle-class in cities like San Francisco or San Diego.
The Reality of the Progressive Tax System
California uses ten different tax brackets. Ten. That’s a lot compared to the federal system, which only has seven.
It starts at a tiny 1% and climbs all the way up to 12.3%. Wait, where does the 13.3% come from? That’s the Mental Health Services Act. It’s an additional 1% surcharge on any taxable income over $1 million. If you’re making seven figures, Sacramento is definitely taking a hefty slice of the pie.
Let’s look at the actual numbers for single filers. If your taxable income is between $0 and $11,014, you’re in that 1% bucket. Once you cross $11,014 but stay under $26,117, that specific chunk of money is taxed at 2%. This continues upward. By the time you’re earning over $68,347, you’ve hit the 8% bracket. For many professionals in California, this is where the bite starts to feel real.
If you're married and filing jointly, the income thresholds basically double. So, that 1% bracket applies to your first $22,028 of combined income.
Why the "Taxable Income" Number Matters
Don't confuse your salary with your taxable income. They aren't the same. People get this wrong constantly.
Your taxable income is what's left over after you take your deductions. In California, you can choose between the Standard Deduction or Itemized Deductions. For 2025, the standard deduction for a single filer is $5,556. For those married filing jointly, it’s $11,112. It’s not huge, especially compared to the federal standard deduction, but it lowers the starting point of those California 2025 tax brackets.
Breaking Down the 2025 Thresholds
Let's get into the weeds of the specific rates.

For a single person or a married person filing separately, the 4% bracket kicks in at $41,223. The 6% bracket starts at $56,331. If you're lucky enough—or maybe unlucky enough, depending on how you look at your tax bill—to earn over $376,636, you're looking at a 10.3% rate on those top dollars.
It gets steeper.
- 9.3% Rate: Starts at $68,347 for singles and $136,694 for couples.
- 10.3% Rate: Starts at $376,636 for singles and $753,272 for couples.
- 11.3% Rate: Starts at $451,960 for singles and $903,920 for couples.
- 12.3% Rate: Starts at $753,273 for singles and over $1.5 million for couples.
Then, of course, that extra 1% for the millionaires.
It’s a "marginal" system. If you earn $70,000, you don't pay 9.3% on the whole $70k. You pay 1% on the first chunk, 2% on the next, and so on. Only the dollars above $68,347 get taxed at that 9.3% rate. This is the most common misunderstanding in tax history. Seriously.
The Impact of Credits
Brackets are only half the story. California offers some unique credits that can wipe out your tax liability entirely if you qualify.
The California Earned Income Tax Credit (CalEITC) is a big one. It’s designed for low-to-moderate-income working Californians. If you earn less than $30,000, you might be looking at a significant refund, even if you didn't owe much to begin with. Then there’s the Young Child Tax Credit, which can provide up to $1,177 per eligible family.
If you're a renter, don't forget the Nonrefundable Renter’s Credit. It’s small—$60 for singles or $120 for couples—but in a state where rent is astronomical, every little bit helps. To get it, your adjusted gross income has to be below certain limits (usually around $50,000 for singles).
Capital Gains: The California Trap
Here is where California really differs from the federal government.
Federal taxes usually give you a break on long-term capital gains. If you hold a stock for over a year, you pay a lower rate (0%, 15%, or 20%).

California? Nope.
Sacramento treats capital gains as regular income. If you sell a house or a bunch of Nvidia stock and make a massive profit, that money gets stacked right on top of your salary. It can easily push you into those 10.3% or 11.3% California 2025 tax brackets very quickly. Investors often forget this and end up with a nasty surprise come April.
Standard Deduction vs. Itemized: The Math Has Changed
Ever since the federal Tax Cuts and Jobs Act capped the SALT (State and Local Tax) deduction at $10,000, itemizing has become less common for many. However, California still allows you to itemize on your state return even if you take the standard deduction on your federal return.
You might want to itemize if you have:
- Large mortgage interest payments.
- Significant charitable contributions.
- Uninsured casualty or theft losses.
- High medical expenses (though they must exceed a certain percentage of your income).
For most renters or people with small mortgages, the standard deduction is the way to go. It’s simpler. No receipts to track. Just take the $5,556 (for singles) and move on with your life.
The "Sun" Factor: Business and Freelance Income
If you’re a freelancer or own a small business in the CA, the California 2025 tax brackets apply to your net profit. But there’s a catch. Most LLCs in California have to pay an $800 annual franchise tax just for the privilege of existing.
If your LLC makes over $250,000, you start paying an additional "LLC Fee" based on gross total income. This is separate from your personal income tax. It's essentially a tax on being successful.
How to Prepare for the 2025 Tax Year
Waiting until April 2026 to think about this is a recipe for stress.
First, check your withholdings. If you’re an employee, look at your paystub. If the amount being sent to the FTB seems low compared to these brackets, you might want to adjust your DE 4 form (the California version of the W-4).

Second, look at your retirement contributions. Contributions to a traditional 401(k) or 403(b) lower your taxable income for both federal and state purposes. If you’re on the edge of the 9.3% bracket, bumping up your retirement savings by a few thousand dollars could keep that money in your own pocket (eventually) rather than the state's.
Third, keep track of your "Above-the-Line" deductions. These are things like educator expenses or student loan interest. While California generally follows federal rules, there are always slight variations. For instance, California doesn't tax Health Savings Account (HSA) contributions the same way the feds do. In California, HSA contributions are often taxed as income. It's a weird quirk, but it matters.
Helpful Resources
If you want to dive into the exact decimal points, the California Franchise Tax Board website is the source of truth. They release the finalized, inflation-adjusted tables every autumn. You can also use their "Tax Calculator" tools to run scenarios.
Real World Example: The San Jose Engineer
Let's look at "Sarah," a software engineer in San Jose. She's single and earns $160,000.
After her federal 401(k) contribution of $23,500 and the California standard deduction of $5,556, her taxable income for the state is roughly $130,944.
Looking at the California 2025 tax brackets, she’s not paying 9.3% on $130,944. She’s paying:
- 1% on the first $11k.
- 2% on the next $15k.
- 4% on the next $15k.
- 6% on the next $15k.
- 8% on the next $12k.
- 9.3% only on the amount between $68,347 and $130,944.
Her effective tax rate—the actual percentage of her total income that goes to the state—is likely closer to 7% or 8%, not the top bracket of 9.3%. Understanding this distinction is the difference between tax panic and tax planning.
Actionable Next Steps
Don't let the numbers overwhelm you. Taxes are a game of organization.
- Review your DE 4: Make sure your employer is taking out enough. If you had a big bill last year, increase your withholding now.
- Max out your 401(k): This is the single most effective way to drop yourself into a lower California tax bracket.
- Track your residency: If you spend significant time outside of California but still claim residency, keep a log. The FTB is notorious for "residency audits" if they think you're trying to dodge their brackets by claiming you live in Nevada or Texas.
- Check for credits: Specifically, see if you qualify for the CalEITC or the Renter's Credit. These are literally free money that people leave on the table every year.
- Consult a pro: If your income involves K-1s, rental properties, or complex stock options (RSUs/ISO), a CPA who specializes in California law is worth their weight in gold. The state's rules on "source income" are incredibly complex.
The 2025 tax year is already underway. The sooner you align your finances with these updated brackets, the less painful that final calculation will be. Keep an eye on your adjusted gross income, stay organized with your receipts if you plan to itemize, and always remember that in California, the state wants its share of every dollar you earn, regardless of how you earned it.
The brackets are set. Now it's just about how you navigate them.
