California State Tax 2026: Rates, Brackets & What You Actually Owe
California's 13.3% top income tax rate gets all the headlines, but most Californians have no idea what rate they actually pay — or why their effective state tax rate is substantially lower than that top bracket suggests. This guide dismantles the confusion: here are the exact 2026 California Franchise Tax Board tax brackets, the real story on SDI, the sales tax calculation, property tax limitations under Proposition 13, and the specific strategies that meaningfully reduce your California tax bill.
Key Takeaways
- • California has the highest top state income tax rate in the U.S. — 13.3% on income over $1 million (12.3% base + 1% Mental Health Services Tax).
- • Most Californians fall in the 9.3% bracket: it applies to all income between $70,607 and $371,479 for single filers in 2026.
- • California's standard deduction is only $5,706 (single) — compared to $16,100 federally — making state taxable income significantly higher than federal taxable income for many filers.
- • As of 2024, California eliminated the SDI wage cap: the 1.2% SDI rate now applies to all wages with no ceiling.
- • California taxes Social Security benefits, 401(k) distributions, and IRA withdrawals as ordinary income — unlike many other states.
The Real Numbers
According to the Tax Foundation's 2026 State Individual Income Tax Rates and Brackets report, California's 13.3% top marginal rate ranks #1 in the nation — more than 2 percentage points above Hawaii's #2 rate of 11%. Yet the California Franchise Tax Board's own statistics show the average effective state income tax rate paid by California filers is approximately 5.6% — because the vast majority of residents fall in brackets well below 13.3%.
California Income Tax Brackets 2026: Single Filers
California uses nine income tax brackets, with rates ranging from 1% to 12.3%. These are applied to your California Taxable Income — your federal AGI with California adjustments, reduced by the California standard deduction or itemized deductions. Note that California's standard deduction is dramatically lower than the federal version.
| Taxable Income (Single) | Tax Rate | Tax on This Bracket |
|---|---|---|
| $0 – $10,756 | 1% | Up to $107.56 |
| $10,757 – $25,499 | 2% | Up to $294.84 |
| $25,500 – $40,245 | 4% | Up to $589.80 |
| $40,246 – $55,866 | 6% | Up to $937.20 |
| $55,867 – $70,606 | 8% | Up to $1,179.12 |
| $70,607 – $371,479 | 9.3% | Up to $27,981.58 |
| $371,480 – $445,771 | 10.3% | Up to $7,651.91 |
| $445,772 – $742,953 | 11.3% | Up to $33,593.87 |
| $742,954 – $999,999 | 12.3% | Up to $31,615.77 |
| $1,000,000+ | 13.3% | On all income above $1M |
Source: California Franchise Tax Board (FTB), 2026 tax year schedules. The 13.3% rate applies to the Mental Health Services Tax, which is the 1% surcharge on top of the 12.3% bracket. It is permanent and has been in place since 2004 when California voters passed Proposition 63.
California Income Tax Brackets 2026: Married Filing Jointly
| Taxable Income (MFJ) | Tax Rate |
|---|---|
| $0 – $21,512 | 1% |
| $21,513 – $50,998 | 2% |
| $50,999 – $80,490 | 4% |
| $80,491 – $111,732 | 6% |
| $111,733 – $141,212 | 8% |
| $141,213 – $742,958 | 9.3% |
| $742,959 – $891,542 | 10.3% |
| $891,543 – $1,485,907 | 11.3% |
| $1,485,908 – $1,999,999 | 12.3% |
| $2,000,000+ | 13.3% |
For married filing jointly filers, the $1 million Mental Health Services Tax threshold is applied per return — meaning a household earning $1.5 million combined pays 13.3% on the $500,000 above $1 million, not each individual. This differs from some states that apply the high-income surcharge per spouse.
The Standard Deduction Trap: Why California Tax Is Higher Than Federal
One of the most frequently misunderstood aspects of California state tax is the enormous gap between federal and California standard deductions. In 2026:
| Filing Status | Federal Standard Deduction 2026 | California Standard Deduction 2026 | Gap |
|---|---|---|---|
| Single | $16,100 | $5,706 | $10,394 more taxable in CA |
| Married Filing Jointly | $32,200 | $11,412 | $20,788 more taxable in CA |
| Head of Household | $24,150 | $11,412 | $12,738 more taxable in CA |
For a single filer earning $80,000, the federal standard deduction reduces taxable income to $63,900. California only allows $5,706, leaving California taxable income of $74,294. The extra $10,394 in California taxable income — taxed at 9.3% — adds approximately $966 to the state tax bill compared to what a naive bracket reading might suggest. This gap is one reason California's effective tax rates feel high even for middle-income earners.
California does not conform to the federal personal exemption (which is currently $0 under the 2017 TCJA), but California provides its own personal exemption credits: $144 for single filers, $288 for married filing jointly (2026), and $433 per dependent. These are credits, not deductions, so they directly reduce your California tax bill dollar-for-dollar.
California State Disability Insurance (SDI): The Uncapped Tax Since 2024
California's State Disability Insurance program provides short-term disability benefits and funds Paid Family Leave. Beginning January 1, 2024, California Senate Bill 951 eliminated the SDI wage base cap — previously, SDI was only withheld on wages up to a set ceiling. Now the 1.2% SDI rate applies to all wages with no maximum. This change significantly increased SDI costs for high earners.
SDI Cost Impact by Income Level (2026)
$75,000 salary: 1.2% × $75,000 = $900/year in SDI
$200,000 salary: 1.2% × $200,000 = $2,400/year in SDI
$500,000 salary: 1.2% × $500,000 = $6,000/year in SDI
Prior law (2023): SDI was capped at a wage base of ~$153,164, maximum withholding ~$1,378/year regardless of salary
The SDI you pay IS deductible — but only as a state tax deduction on Schedule A (itemized deductions), not above-the-line. Californians who take the federal standard deduction receive no federal tax benefit from SDI payments.
SDI withheld by your employer is reported on Form W-2 in Box 14 (labeled "CASDI" or "CA SDI"). Self-employed individuals can opt into the SDI program voluntarily through the Employment Development Department (EDD).
California Sales Tax: The Highest Base Rate in America
California's statewide base sales tax rate is 7.25% — the highest state base sales tax in the country according to the Tax Foundation's 2026 Sales Tax Rate report. Most counties and cities add local district taxes ranging from 0.10% to 2.00%, pushing combined rates significantly higher in densely populated areas.
| Location | Combined Sales Tax Rate (2026) |
|---|---|
| California statewide base | 7.25% |
| Los Angeles County | 10.25% |
| San Francisco | 8.625% |
| San Diego | 7.75% |
| Sacramento | 8.75% |
| San Jose (Santa Clara County) | 9.375% |
Groceries (unprepared food), prescription medications, and some medical devices are exempt from California sales tax. Online purchases from out-of-state retailers are subject to California use tax at the same rates — technically the buyer's responsibility to self-report on their California tax return, though this is widely under-reported for small purchases. Effective April 1, 2026, the California Department of Tax and Fee Administration (CDTFA) updated several district tax rates; check your specific city or county for current combined rates.
California Property Tax: Proposition 13 Explained
California property taxes are governed by Proposition 13, passed by voters in 1978. Prop 13 caps the property tax rate at 1% of a property's assessed value, plus voter-approved bonds and assessments that typically add 0.1% to 0.5%. The assessed value is reset to market value only at sale — between sales, annual increases are capped at 2%.
This creates a dramatic divergence between longtime owners and recent buyers in high-appreciation markets. According to the California State Board of Equalization's 2024 Annual Report, the average effective property tax rate in California was approximately 0.7% of current market value — far below the national average of 1.1% (per Lincoln Institute of Land Policy). However, a homeowner who bought in the San Francisco Bay Area in 2020 at $1.5 million pays roughly $10,500 per year in property taxes (at 0.7%), while a neighbor who bought the same house in 1998 for $350,000 pays approximately $5,600 per year — even though both homes are now worth $1.5 million.
Proposition 19 (passed November 2020) significantly changed the rules for parent-to-child and grandparent-to-grandchild property transfers. Beginning February 16, 2021, inherited property only retains the inherited assessed value if the child uses it as a primary residence, and only up to $1 million above the inherited assessed value. Properties transferred for investment, rental, or vacation use are now reassessed at full market value — a major change from the prior unlimited exclusion.
California Taxes Retirement Income: Key Differences From Federal Rules
California is one of the few states that taxes all major categories of retirement income. This is a critical planning consideration for retirees and near-retirees:
- Social Security Benefits: California is one of only a handful of states that taxes Social Security benefits as ordinary income. The federal government exempts up to 15% and taxes up to 85% depending on combined income — California offers no equivalent exclusion.
- 401(k) and IRA Distributions: Taxed as ordinary income at full California rates. If you withdraw $50,000 from a traditional IRA and you're in the 9.3% bracket, you owe approximately $4,650 in California income tax on that withdrawal alone, in addition to federal tax.
- Military Pensions: California taxes military retirement pay, making it one of only a small number of states to do so. Active duty pay earned outside California is exempt, but military pension income is fully taxable by the FTB.
- Railroad Retirement Benefits: Exempt from California income tax (federal law preemption under the Railroad Retirement Act).
- California Public Employee Pensions (CalPERS/CalSTRS): Fully taxable as ordinary income to California residents.
For retirees considering relocation, the California tax burden on retirement income is a major driver. A comparison of no-income-tax states versus California can be striking — see our no income tax states guide for a full analysis.
California Alternative Minimum Tax (AMT)
California has its own Alternative Minimum Tax, separate from the federal AMT. The California AMT rate is 7% on the first $232,668 of AMT income, and 9.3% on AMT income exceeding that threshold (2026). Unlike the federal AMT, California's AMT exemption phases out beginning at $312,026 for single filers and $624,051 for MFJ filers.
California AMT most commonly affects taxpayers with large incentive stock option (ISO) exercises, accelerated depreciation, certain long-term capital gains, and tax preference items. High-income residents in the tech sector who exercise ISOs need to model both federal and California AMT carefully — the California AMT can create a significant state tax liability even when federal AMT is not triggered.
FTB Filing Requirements and Key Deadlines
California income tax returns are filed using FTB Form 540 (residents), Form 540NR (part-year and nonresidents), or Form 540 2EZ (simple filers). Key 2026 filing facts:
- Filing deadline: April 15, 2027 for 2026 tax year returns (same as federal)
- Automatic extension: California automatically grants a 6-month extension to October 15, 2027 — no form required. But this extends the filing deadline, not the payment deadline. Tax owed must be paid by April 15 to avoid penalties and interest.
- Estimated tax payments: Required if you expect to owe $500 or more in California tax and your withholding and credits won't cover the liability. Due April 15, June 15, September 15 (2026), and January 15, 2027.
- Filing requirement thresholds (2026): Single under 65 must file if gross income exceeds $21,862. Married filing jointly must file if combined gross income exceeds $43,724.
California does not allow e-filing of all forms — certain amended returns and complex forms must be paper-filed. The FTB administers CalFile, a free e-filing system for simple returns. MyFTB is the online portal for viewing notices, making payments, and checking refund status.

California Tax Planning Strategies That Actually Work
1. Maximize Pre-Tax Retirement Contributions
California conforms to federal 401(k) and IRA deduction rules. Maximizing pre-tax retirement contributions reduces both federal and California taxable income dollar-for-dollar. A single filer in the 9.3% California bracket who contributes the maximum $23,500 to a 401(k) in 2026 saves approximately $2,186 in California income tax — in addition to the federal savings.
2. Harvest Capital Losses to Offset California Capital Gains
California does not have preferential long-term capital gains rates — all capital gains are taxed as ordinary income at rates up to 13.3%. This means tax-loss harvesting is even more valuable in California than in other states. Strategically realizing capital losses to offset gains can save both the federal capital gains rate and the full California marginal rate on the same income.
3. Use Health Savings Accounts (HSAs)
California does not conform to federal HSA tax treatment — HSA contributions are NOT deductible on your California return, and HSA earnings are taxable in California. This is a significant difference: while an HSA gives you a federal deduction, California treats it as a regular taxable account. Californians should still use HSAs for the federal tax benefit, but should not count on state tax savings. For HSA strategy details, see our HSA tax benefits guide.
4. Real Estate: Leverage the Mortgage Interest Deduction
California conforms to the federal mortgage interest deduction on up to $750,000 of acquisition indebtedness for homes purchased after December 15, 2017. For loans originated before that date, California follows the prior $1 million limit — and California does not fully conform to the post-TCJA federal rule, so older California law may apply for pre-2018 loans. Given California's high real estate prices, the mortgage interest deduction is one of the most significant itemized deductions available to California homeowners.
5. Understand California's Non-Conformity Traps
California has significant areas of non-conformity with federal tax law that create separate state tax obligations:
- California does not conform to the federal SALT deduction cap — California state and local taxes are deductible without limit on the California return when itemizing
- California does not recognize Section 1031 exchanges for personal property (only real property)
- California does not conform to federal bonus depreciation rules (Section 168(k)) — accelerated depreciation is limited for California purposes
- California requires adding back the deduction for 50% of self-employment taxes on the California return
- California does not conform to the federal qualified opportunity zone deferral rules
Tracking these non-conformity items requires maintaining a separate California tax basis and schedule for certain assets. Use our income tax calculator to model your combined federal and state tax liability with different income scenarios.
Frequently Asked Questions
What is California's state income tax rate for 2026?
California has nine income tax brackets ranging from 1% to 12.3% for 2026, plus a 1% Mental Health Services Tax surcharge on income over $1 million, making the effective top rate 13.3% — the highest state income tax rate in the United States. The California Franchise Tax Board administers collections. Most middle-income earners fall in the 9.3% bracket.
Is California income tax the highest in the US?
Yes. California's 13.3% top marginal income tax rate is the highest state income tax rate in the nation as of 2026, according to the Tax Foundation's 2026 State Individual Income Tax Rates report. Hawaii is second at 11%, followed by New Jersey at 10.75%. Nine states have no income tax at all: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming.
What is California's standard deduction for 2026?
California's standard deduction for 2026 is $5,706 for single filers and $11,412 for married filing jointly — far lower than the $16,100 and $32,200 federal standard deductions. This means California taxable income is significantly higher than federal taxable income for most residents who take the standard deduction federally. California also provides personal exemption credits ($144 single, $288 MFJ) that directly reduce the tax bill.
Does California tax retirement income and Social Security?
Yes to both. California taxes Social Security benefits as ordinary income — one of only a handful of states to do so. California also fully taxes 401(k) and IRA distributions, pensions, and most retirement income sources at regular income tax rates. Military retirement pay from active duty service is also taxable. This makes California a high-tax state for retirees compared to states like Florida, Texas, or Nevada that exempt retirement income entirely.
What is the California SDI rate for 2026?
The 2026 California SDI rate is approximately 1.2% applied to all wages with no wage base cap — a major change that took effect January 1, 2024 under SB 951. Previously, SDI was capped at a wage base of approximately $153,164. High earners now pay SDI on their entire salary. SDI funds short-term disability and Paid Family Leave. The withholding appears on Form W-2 in Box 14 as "CASDI."
How does Proposition 13 affect California property taxes?
Proposition 13 caps property tax at 1% of a property's assessed value (plus voter-approved additions), with assessed value only reset to market value at sale. Annual increases are limited to 2%. This creates huge disparities between longtime owners and recent buyers in high-appreciation areas — a homeowner who bought in 2002 may pay far less than a neighbor who bought the identical home recently. Prop 19 (2020) changed inheritance transfer rules, now requiring children to use inherited property as a primary residence to preserve the parent's assessed value.
