California residents generally calculate their income taxes under two different sets of rules: federal income tax laws and California state income tax laws. The two systems use different tax brackets, income thresholds, deductions, and treatment of certain types of income.
For many taxpayers, California’s tax brackets begin at lower income levels, and the state’s standard deduction is considerably smaller than the federal deduction. Understanding these differences can help individuals and families better anticipate their overall tax liability.
The tax consultants at Robert Hall & Associates help Los Angeles households evaluate both federal and California tax obligations through our tax advisory services.
The brackets and deductions below apply to tax year 2026, generally covering income earned during 2026 and reported on tax returns filed in 2027.
California vs. Federal Tax Brackets: 2026 Comparison
Both federal and California income taxes use progressive tax systems. This means different portions of taxable income are taxed at different rates, rather than applying one rate to all income.
Here is a side-by-side comparison of the major differences for 2026:
| Tax Feature | Federal | California |
| Number of ordinary income tax brackets | 7 | 9 |
| Ordinary income tax rates | 10% to 37% | 1% to 12.3%, plus an additional 1% on taxable income above $1 million |
| Standard deduction, single | $16,100 | $5,900 |
| Standard deduction, married filing jointly | $32,200 | $11,800 |
| Long-term capital gains | Generally 0%, 15%, or 20%, with special rules for certain gains | Taxed at regular state income tax rates |
| Qualified Business Income deduction | Available to eligible taxpayers | California does not conform to the federal deduction |
These differences mean that the same income can produce different taxable income calculations and tax liabilities on federal and California returns.
How Do Federal Income Tax Brackets Work in 2026?
The IRS uses seven federal income tax brackets, ranging from 10% to 37%.
For the 2026 tax year:
- The lowest federal income tax rate is 10%.
- The highest federal income tax rate is 37%.
- The 37% bracket begins above $640,600 in taxable income for single filers.
- The federal standard deduction is $16,100 for single filers.
- Married couples filing jointly generally receive a $32,200 standard deduction.
Under the IRS’s 2026 inflation adjustments, the 22% federal bracket applies to taxable income above $50,400 through $105,700 for single filers.
Because the system is progressive, taxpayers do not pay their highest marginal rate on all their income. Each rate applies only to the portion of taxable income falling within that bracket.
How Do California Income Tax Brackets Work in 2026?
California also uses a progressive income tax system, but it has nine regular tax brackets ranging from 1% to 12.3%.
For the 2026 tax year, the California Franchise Tax Board adjusted its income thresholds for inflation.
Key figures include:
- Nine regular income tax brackets, ranging from 1% to 12.3%
- The 12.3% bracket begins above $768,213 in taxable income for single filers
- An additional 1% tax applies to California taxable income above $1 million
- A $5,900 standard deduction for single filers
- An $11,800 standard deduction for married couples filing jointly
The additional 1% tax on taxable income above $1 million brings California’s highest marginal individual income tax rate to 13.3%.
Like the federal system, California applies each tax rate only to the income within that bracket.
How Big Is the Standard Deduction Gap in 2026?
One of the most noticeable differences between federal and California income taxes is the standard deduction.
For 2026, a single taxpayer receives a federal standard deduction of $16,100 compared with $5,900 in California, a difference of $10,200.
For married couples filing jointly, the federal standard deduction is $32,200 compared with $11,800 in California, a difference of $20,400.
Consider a simplified example of a single taxpayer earning $100,000 in wages with no other income or adjustments who claims the standard deduction on both returns.
- Federal taxable income: $100,000 minus $16,100 = $83,900
- California taxable income: $100,000 minus $5,900 = $94,100
This example assumes no other applicable deductions, adjustments, or differences between federal and California tax treatment.
The difference in taxable income does not automatically mean the California tax bill will be higher. Each system applies its own progressive rates to the applicable taxable income.
Are Capital Gains Taxed Differently in California?
Yes. Federal and California tax treatment can differ significantly when taxpayers sell investments or real estate.
Qualifying long-term capital gains may receive preferential federal tax rates of 0%, 15%, or 20%, depending on the taxpayer’s income and the type of gain.
Certain gains, including depreciation-related real estate gains and collectibles, may be subject to different federal rules.
California generally does not provide preferential tax rates for long-term capital gains. Instead, capital gains are taxed using the state’s regular income tax brackets.
For taxpayers selling appreciated stock, investment property, or other assets, the gain can increase California taxable income and potentially push a portion of that income into a higher marginal bracket.
Reviewing both federal and California tax consequences before a significant sale can help taxpayers better understand the potential tax impact.
When Does the 9.3% California Tax Bracket Start?
California’s 9.3% income tax bracket covers a relatively wide range of taxable income.
For the 2026 tax year, the 9.3% bracket begins above:
- $75,197 for single filers
- $150,394 for married couples filing jointly
Higher tax rates apply only to income exceeding the applicable thresholds, not to the taxpayer’s entire income.
For example, if a taxpayer moves into a higher California tax bracket, only the portion of taxable income above that bracket’s starting threshold is subject to the higher rate.
Understanding the difference between marginal and effective tax rates can help taxpayers avoid overestimating the impact of additional earnings.
How to Reduce California State Income Tax
Tax planning opportunities depend on the taxpayer’s income, filing status, investments, business activity, and other circumstances.
Several strategies may be worth reviewing:
- Retirement Contributions: Eligible traditional 401(k) contributions and deductible IRA contributions may reduce taxable income. IRA contribution deadlines and deduction limits depend on applicable tax rules.
- California Itemized Deductions: Some taxpayers may benefit from itemizing deductions on their California return even when taking the federal standard deduction.
- Timing a Sale: In certain circumstances, the timing or structure of a transaction may affect which tax year recognizes the gain. Installment sales and other strategies have specific eligibility requirements.
- Dual-Income Withholding Review: Married couples with two incomes may benefit from reviewing withholding on both paychecks to determine whether their combined tax liability is adequately covered.
Not every strategy works for every taxpayer. Reviewing the applicable federal and California rules before making significant decisions can help identify opportunities and avoid unnecessary surprises.
Understanding Your Marginal vs. Effective Tax Rate
Your marginal tax rate is the rate applied to the last dollar of taxable income within your highest applicable bracket.
Your effective tax rate measures your total tax liability relative to an income measure, such as taxable income or total income.
Because both federal and California income taxes use progressive brackets, your effective rate is generally different from your highest marginal rate.
Understanding this distinction is particularly useful when evaluating raises, bonuses, investment gains, retirement contributions, and other changes in income.
California Tax Planning for Los Angeles Households
California’s tax rules can create different results from federal tax calculations, particularly for households with multiple income sources, significant investment gains, or changing financial circumstances.
Reviewing both returns throughout the year can help taxpayers understand how income, deductions, credits, and planning decisions affect their overall tax position.
