The federal One Big Beautiful Bill Act (OBBBA), passed in July 2025, changed how California tax planning in 2026 and federal taxes interact. And California’s Franchise Tax Board (FTB) has its own updated numbers for credits, deductions, and income thresholds that take effect this filing season.
This guide covers everything about California income tax rates, credits available right now, deductions that actually move the needle, and strategies that work in 2026.
What Changed in California Tax Law for 2026 and What Carries Into 2026
California does not automatically follow federal tax law. That matters more than ever in 2026.
The OBBBA made most TCJA provisions permanent at the federal level. California conforms to some of them, but not all. The federal SALT deduction cap ($10,000) still applies to your federal return.
California does not cap the state and local tax deduction on California returns in the same way. This creates a planning gap that smart taxpayers use.
A Notable California Update: Alimony Rules ChangedFor divorces finalized on or after January 1, 2026, California no longer allows payers to deduct alimony on state returns, aligning closer to post-TCJA federal treatment. |
California tax brackets, credit limits, and standard deductions are adjusted annually using the California Consumer Price Index. The 2025 figures (filed in 2026) are confirmed and final from the FTB.
How California Tax Planning Works in 2026
Tax planning in 2026 in California means reducing what you owe California separately from what you owe the IRS. The state does not conform to every federal deduction, credit, or exclusion.
- California taxes all worldwide income for residents
- California income tax rates run from 1% to 12.3%, with an extra 1% Mental Health Services Act (MHSA) surcharge on taxable income above $1 million, making the real top rate 13.3% (the highest state rate in the U.S.).
- Non-residents only pay California tax on California-sourced income
- Part-year residents file Form 540NR
California Income Tax Rates in 2026 and How They Affect Planning
California runs nine progressive tax brackets. Per the FTB’s 2026 withholding schedules and EDD guidance, the marginal rates are
| Rate | Applies To |
| 1% | Lowest income bracket |
| 2% | Next income tier |
| 4% | — |
| 6% | — |
| 8% | — |
| 9.3% | Upper-middle income |
| 10.3% | — |
| 11.3% | — |
| 12.3% | Highest bracket |
| +1% MHSA | Income over $1,000,000 |
The 2025 tax year brackets are inflation-adjusted. For the 2026 tax year (filed in 2027), the FTB will release updated thresholds; those are not finalized yet as of February 2026.
How California Tax Brackets Apply in a Real-World ScenarioSay you earn $80,000 as a single filer in California for 2025. You do not pay 9.3% on all $80,000. You pay 1% on the first bracket, 2% on the next, and so on up to your top bracket. Only the income that falls inside the 9.3% bracket gets taxed at 9.3%. This is why California tax planning in 2026 focuses on which bracket your top dollars land in, not your total income. |
Key Details That Impact California Tax Planning in 2026
California tax planning in 2026 gets complicated fast because of how the state treats income differently from the IRS.
- California taxes Social Security income (the federal government does not, for lower earners)
- California does not allow the federal standard deduction; it uses its own lower amount
- California does not recognize Roth IRA conversion tax benefits the same way
- Stock options and RSU income follow California source rules even if you leave the state
Legislative Changes That Influence California Tax Planning Decisions
The OBBBA made the 20% pass-through deduction permanent at the federal level. California does not conform to this deduction. California business owners claiming the Section 199A deduction on their federal return get nothing from California for it.
California also maintained its own net operating loss (NOL) rules. The state had temporarily suspended NOL deductions in prior years; those suspensions have since expired, so NOL carryforwards are usable again in 2026, subject to current FTB rules.
Coordinating California and Federal Tax Planning
Tax planning in 2026 works best when you treat federal and California taxes as two separate puzzles to find where they overlap.
- Retirement contributions reduce both federal and California taxable income (401k, traditional IRA)
- Health Savings Account (HSA) contributions reduce federal taxes but not California income taxes. California does not conform to the federal HSA exclusion
- Capital gains rates are the same in California, regardless of holding period. California taxes all capital gains as ordinary income
- Mortgage interest is deductible on both returns (subject to limits)
California Tax Credits Available in 2026
California tax credits reduce what you owe dollar-for-dollar. Some are refundable, meaning the FTB pays you back even if your tax bill is zero.
California Earned Income Tax Credit (CalEITC)
For tax year 2025 (filed in 2026), the CalEITC offers up to $3,756 for working Californians earning up to $32,900. It is refundable. ITIN holders qualify.
Over 3.4 million Californians claimed it in 2025, receiving more than $1.4 billion combined (FTB, February 2026). Claim it on Form FTB 3514.
Young Child Tax Credit (YCTC)
If you qualify for CalEITC and have a child under 6 years old, you get up to $1,189 extra. For tax year 2025, you can qualify even with zero earned income if your wages don’t exceed $35,640 and your net loss doesn’t exceed $35,640.
Foster Youth Tax Credit (FYTC)
Former foster youth ages 18–25 at the end of the tax year get up to $1,189 refundable. If both spouses qualify, the household gets up to $2,378. Claim it on FTB 3514 alongside CalEITC.
Child and Dependent Care Expense Credits
California offers a percentage-based credit for childcare expenses for working parents. The credit rate depends on your income. It is non-refundable; it reduces what you owe but does not pay out if your bill hits zero.
Adoption-Related Tax Credits in California
California’s adoption cost credit covers qualified expenses for adopting children. Amounts and eligibility rules are confirmed through the FTB annually. For current thresholds, check FTB Publication 1001.
Head of Household Credits for Joint Custody Situations
California provides a joint custody head of household credit for taxpayers who share custody and qualify for head of household filing status. This is a non-refundable credit. It applies when a non-custodial parent qualifies under specific FTB rules.
Dependent Parent Tax Credit
If you support a parent who is not your dependent but qualifies under California rules, you may claim a credit. This is a non-refundable credit listed on Form 540. The FTB confirms eligibility annually.
California Renter’s Tax Credit
Renters who do not own property and meet the California income thresholds get a flat credit: $60 for single filers and $120 for married/RDP joint filers (for tax year 2025).
It is non-refundable. You must live in a California residence for which you paid rent, and you cannot be claimed as a dependent.
Senior Head of Household Tax Credit
California residents 65 or older who qualify as head of household get an additional credit. For 2025, the credit is a percentage of California’s adjusted gross income, subject to income limits. Check the FTB 2025 Form 540 instructions for the exact amount.
California Motion Picture and Film Production Tax Credit
California’s film tax credit runs as a competitive program managed by the California Film Commission. Productions meeting spending thresholds in California get a credit against California income tax. The current program (Program 4.0) offers up to 25–35% of qualified spending.
Low-Income Housing Tax Credit (LIHTC) in California
The state LIHTC works alongside the federal LIHTC to fund affordable housing construction. California’s credit is administered by the California Tax Credit Allocation Committee (CTCAC). Investors in qualifying projects claim the credit over 10 years.
Clean Energy and Environmental Tax Credits in California
California’s clean energy credits include the California Competes Tax Credit (for businesses committing to jobs) and various credits tied to clean vehicle purchases through CARB programs.
The IRA-era federal EV credits still interact with state planning. California does not offer a separate state EV credit but integrates with federal incentives.
Business and Economic Development Tax Credits
The California Competes Tax Credit is a negotiated credit for businesses creating jobs or expanding in California. Administered by the Governor’s Office of Business and Economic Development (GO-Biz), the credit runs in quarterly application rounds.
California also offers the New Employment Credit (NEC) for hiring in designated geographic areas.
How California Tax Deductions Fit Into a Strategic Tax Plan
The California standard deduction for 2025 (the tax year you file in 2026) is:
- $5,706: Single or Married Filing Separately
- $11,412: Married Filing Jointly, Head of Household, or Qualifying Surviving Spouse
These numbers are far lower than the federal standard deduction. Most Californians with significant mortgage interest, property taxes, or medical costs do better itemizing on their state return, even if they take the federal standard deduction.
Itemized Deductions and California-Specific Limitations
California allows mortgage interest, property taxes, charitable contributions, and certain medical expenses as itemized deductions. But California does not allow the federal deduction for state and local taxes paid to other states. California also does not allow the qualified business income (Section 199A) deduction.
Strategic California Tax Planning Strategies for 2026
Income Timing and Deferral Strategies
If you expect to earn significantly more in 2026 than in 2025, push income into 2025 where possible or defer it into 2027. A $50,000 bonus hitting in the 9.3% bracket costs less than one hitting the 10.3% bracket.
Multi-State Tax Planning for California Residents
California aggressively audits people who claim to have moved out of the state. The FTB looks at where your family lives, where you vote, and where you hold a driver’s license.
Remote workers employed by California companies while living out of state still face potential California tax exposure on wages earned during California assignments.
Integrating Estate and Gift Tax Planning
California does not have a state estate tax or gift tax. But California residents with large estates still face federal estate tax exposure. Irrevocable trusts, gifting programs, and business entity structuring can reduce the taxable estate without California-specific complications.
Business Entity and Structure Optimization
California charges an $800 minimum franchise tax on LLCs, LPs, and corporations, even if they make nothing. For LLCs, the annual fee scales up based on gross receipts. Multi-entity structures sometimes create unnecessary franchise tax exposure. Review the entity structure every year.
Maximizing Credits and Layering Deductions
Stack credits in the right order. Claim CalEITC first, then YCTC, then FYTC; they build on each other. Non-refundable credits should offset tax liability created after refundable credits reduce the bill. Applying them in the wrong order wastes money.
Planning Ahead for New and Changing Tax Laws
California’s legislature meets annually. Bills affecting business credits, housing credits, and income sourcing rules pass mid-year. California tax planning in 2026 is watching the California Legislative Information site for anything moving through the Senate or Assembly that could affect your 2026 tax year filing.
Record-Keeping and California Tax Compliance
California has a four-year statute of limitations for income tax audits, longer if income is substantially underreported. Keep W-2s, 1099s, K-1s, receipts for business expenses, and all credit documentation for at least five years.
The FTB uses data-matching from IRS records, so discrepancies between your federal and state returns flag audits.
Industries Where California Tax Planning Has the Biggest Impact
Tax Planning for Film and Television Production
Productions using the California Film Tax Credit must apply and receive allocation before spending. Credits can be sold or transferred, a valuable option for smaller productions that do not have large California tax bills to offset.
Tax Planning for Clean Energy and Environmental Businesses
Solar, EV charging, battery storage, and clean fuel businesses in California intersect federal IRA credits with state enterprise zone incentives.
Planning the timing of qualified property purchases affects both federal bonus depreciation and California’s separate depreciation rules (California does not conform to federal bonus depreciation; assets depreciate more slowly for state purposes).
Tax Planning for Real Estate Investors and Developers
California’s Prop 13 caps annual property tax increases at 2%, but reassessment occurs on sale. For developers and investors, 1031 exchanges work federally, but California imposes a clawback mechanism if you exchange into out-of-state property. Know this before you execute any exchange.
Tax Planning for Technology and Manufacturing Businesses
R&D tax credits exist at both the federal level and in California. California’s Research Credit (Form 3523) offers a 15% credit on qualified research expenses above a base amount. It is non-refundable but carries forward indefinitely.
Tax Planning for Agriculture and Specialty Producers
California farmers can use income averaging on federal returns (Schedule J), but California does not conform to this provision. Farmers also face different estimated tax rules at the state level. Qualifying farmers can skip the January estimated payment and pay in full by March 1, 2027, for the 2026 tax year.

FAQs
California passed SB 711; alimony paid under divorce agreements signed on or after January 1, 2026, is no longer deductible on state returns. California also rejected the OBBBA's 100% bonus depreciation and the 20% pass-through deduction (Section 199A); both remain unavailable on California returns. Business owners now carry two separate depreciation schedules.
California’s high tax rates mean you need to plan carefully to avoid overpaying. For higher earners, it’s important to manage income timing and use strategies like retirement contributions or deductions to stay in a lower bracket. The mental health surcharge for those making over $1 million is another consideration. Proper planning helps minimize taxes and maximize savings.
Yes, in many cases you can. Some credits, like the CalEITC in California, are state-specific. However, credits like those for charitable donations or energy-efficient upgrades can be claimed on both your federal and state taxes. Just make sure you meet the requirements for each credit.
Keep receipts for expenses like medical bills (over 7.5% of your AGI), property taxes, charitable donations, and business expenses if you’re claiming work-related deductions. Having accurate records will help you claim all your eligible deductions and avoid issues if you’re ever audited.
You may want to change your residency status if you move out of California and no longer spend most of your time here. If you’ve established a home in another state and want to take advantage of lower taxes there, it might make sense to change your residency, but be careful, as California is strict about this. It’s a good idea to talk to a tax pro before making the switch.
