A single filer earning California's median household income of $100,600 owes about $5,264 in California state income tax — an effective state rate of 5.23%. That is state tax only, on top of federal income tax and FICA.

Based on 2025 California rules and 2026 federal rules, with the standard deduction and no other adjustments. Median income is the 2024 Census figure.

Income tax in California

California runs the nation's most graduated income tax, with nine brackets climbing from 1% to 12.3% of taxable income. An additional 1% mental-health surcharge applies to income over $1 million, pushing the true top rate to 13.3% — the highest in the nation — though that surcharge is not modeled here. The standard deduction is small ($5,706 single / $11,412 married filing jointly), so most of a paycheck is exposed to the bracket schedule.

California income tax structure (2025)

California uses 9 progressive brackets on income above a $5,706 standard deduction (single). Single-filer brackets:

$0 – $11,0791%
$11,080 – $26,2642%
$26,265 – $41,4524%
$41,453 – $57,5426%
$57,543 – $72,7248%
$72,725 – $371,4799.30%
$371,480 – $445,77110.30%
$445,772 – $742,95311.30%
over $742,95412.30%

Married-filing-jointly thresholds differ (roughly double in most states). Each slice of income is taxed at its own rate — landing in a bracket does not tax your whole income at that rate.

Common questions

What are California's income tax brackets?
California uses nine brackets for 2025: 1% on the first $11,079 of taxable income, rising to 12.3% above $742,953 for a single filer. Taxable income here is your pay after a $5,706 standard deduction ($11,412 joint). Joint filers get their own, wider thresholds.
What is the top income tax rate in California?
12.3%, and it begins at $742,953 of taxable income for a single filer — about $748,659 of gross pay, once the $5,706 California subtracts first is added back. Only income above that point is taxed at that rate; everything below it is taxed in the lower bands.
What is the tax bill on $100,600 in California?
A single filer on California's $100,600 median household income (2024 Census figure) owes roughly $5,264 to California — an effective state rate of 5.2% against a 9.3% marginal bracket — plus about $13,302 of federal income tax.
Does California have a standard deduction?
Yes — $5,706 for a single filer and $11,412 on a joint return, subtracted before California's 1%-to-12.3% schedule is applied. A single filer earning less than $5,706 therefore owes no California income tax at all, and at the state's $100,600 median income it saves about $531 of tax.

Estimates for general informational purposes only; not tax advice. California figures are simplified (credits, local taxes, and AGI adjustments vary) and should be verified with the state Department of Revenue. This estimate does not model California's employee-paid SDI / Paid Family Leave withholding (1.2% of wages in 2025, with no wage cap). California's nine-rate 1%–12.3% schedule is applied with the $5,706 standard deduction for a single filer — not itemized deductions or any California tax credit.
