About California State Tax Calculator 2026

The California State Tax Calculator estimates how much California state income tax and related payroll taxes are taken from your earnings and how they affect your real take‑home pay.

It combines California’s progressive state brackets with State Disability Insurance (SDI), optional Employment Training Tax (ETT) assumptions, plus federal and FICA taxes if you want a complete paycheck view.

California income tax basics

California uses a progressive income tax system with nine personal tax brackets, starting at 1% and reaching up to 12.3% for the highest incomes.

A separate 1% Mental Health Services Tax applies to taxable income above a very high threshold, effectively pushing the top marginal rate to 13.3% for ultra‑high earners.

Standard deductions and credits: California offers standard deductions that differ by filing status and small personal exemption credits that directly reduce state tax.
No local wage income tax: Unlike some states, California does not levy city‑level personal income taxes on wages; major cities like Los Angeles and San Francisco rely on other tax types instead.
SDI and other payroll taxes: Employees also pay State Disability Insurance (about 1.1% up to an annual wage cap), and employers may pay ETT; SDI appears on many paychecks as a separate California line item.

How the California State Tax Calculator works

Step 1 – Compute California taxable income: The calculator starts with gross pay, subtracts pre‑tax benefits, then applies the applicable California standard deduction and personal exemption credits.
Step 2 – Apply CA state brackets: It splits taxable income across California’s nine brackets and multiplies each band by its corresponding rate to determine total state income tax.
Step 3 – Add SDI (and optional extras): The tool applies the current SDI rate to wages up to the statutory cap and may optionally factor in small state payroll surcharges if you enable full payroll mode.
Step 4 – Combine with federal and FICA (optional): When activated, the calculator estimates federal income tax using current U.S. brackets plus Social Security and Medicare contributions to show a complete tax picture.
Step 5 – Break down by paycheck: Annual totals are divided by your chosen pay frequency to display gross pay, each tax type, and net pay per paycheck in a clean, scannable layout.

Outputs you will see

Annual and per‑paycheck CA state tax: Total California state income tax for the year and the amount withheld from each paycheck.

Effective tax rates: The tool reports your effective California state rate and, when full mode is enabled, your combined effective tax rate including federal and FICA.
Take‑home pay summary: A table shows gross pay, state tax, SDI, federal and FICA (if included), and final net income annually and for each paycheck.
