Highest state income tax with 10 brackets from 1% to 13.3%
At $100,000 income, California charges 9.3% marginal state income tax, resulting in approximately $5,762 in state tax burden.

California has the highest state income tax in the United States, with rates ranging from 1% to 13.3% across 10 progressive tax brackets. The state's tax system was designed to be highly progressive, with lower-income earners paying minimal tax while high earners contribute substantially more.
Why these rates? California's high tax rates fund extensive state services including public universities (UC/CSU systems), Medi-Cal (state Medicaid), and social programs. Proposition 30 (2012) temporarily increased rates on high earners, which has been extended multiple times.

Recent changes: The Mental Health Services Tax (1% surcharge) applies to income over $1 million and was made permanent in 2004 via Proposition 63. In 2026, all brackets remain unchanged from 2025.

Tax considerations if moving here:
| State | Tax Rate | Tax on $100K Income | Difference from California |
|---|---|---|---|
| California | 1-13.3% | $5,762 | Baseline |
| Nevada | 0% | $0 | −$5,762 (save) |
| Oregon | 4.75-9.9% | $6,195 | +$433 (higher) |
| Arizona | 2.5% flat | $2,500 | −$3,262 (save) |
Key insight: Moving from California to Nevada or Texas saves $5,762/year at $100K income, $10,991/year at $150K, and over $22,000/year at $250K.
But consider:
California's income tax ranges from 1% to 13.3% across 10 progressive brackets. Most middle-income earners (around $50K-$75K) pay an effective state rate of 3-5%. High earners above $1 million pay the full 13.3% on income exceeding that threshold. The exact rate you pay depends on your taxable income after deductions.
California has 10 tax brackets for 2026. They start at 1% for income up to $10,099 and increase progressively: 2%, 4%, 6%, 8%, 9.3%, 10.3%, 11.3%, 12.3%, and top out at 13.3% for income over $1 million. These are marginal rates, meaning you only pay the higher rate on income within each bracket, not your entire income.
California: $5,762 state tax at $100K income (9.3% marginal rate). Texas/Florida: $0 state income tax (0%). However, Texas property tax averages 1.6% vs California's 0.74% (thanks to Prop 13). On a $600K home, that's $9,600/year in Texas vs $4,440 in California - a $5,160 difference that nearly offsets the income tax savings for homeowners.
California has a standard deduction of $5,363 for single filers in 2026 (follows federal rules adjusted). This means the first $5,363 of income is tax-free. Additionally, the first $10,099 of taxable income (after deductions) is only taxed at 1%. Effectively, a single person making $15,462 pays minimal California tax (<$100/year).
Move if: you're a high earner ($200K+) who rents, work remotely, can establish residency elsewhere (California will audit you), and prioritize cash savings. Stay if: you own an expensive home (Prop 13 caps property tax increases), work in tech/entertainment (salaries often 30-50% higher in CA), value weather/culture/universities, or your equity vests while a CA resident.
