California income tax: rates and San Jose filing questions

FTB provides tax-year and filing-status-specific tables and rate schedules. The reviewed calculator is for 2025 only and excludes Form 540 2EZ and prior years. A 2025 calculator result is not a verified 2026 tax estimate.

Sources checked 2026-10-24. General information maintained by San Jose Tax with AI assistance. We are an independent directory, not a government agency or tax adviser. Verify the instructions for your tax year and circumstances.

Where are the correct California tax brackets?

For the 2025 Form 540 instructions, taxable income of $100,000 or less uses the tax table; above that amount uses the appropriate rate schedule. Use the actual return instructions rather than applying the highest bracket to all income.

Federal income and California adjustments

The 2025 resident Form 540 begins with federal adjusted gross income and applies California adjustments before later deductions and tax calculations. Federal taxable income and California taxable income are not automatically the same amount.

Gather the federal return, W-2s, 1099s and earlier California adjustment schedules. Retirement benefits and investment gains require their own checks; use the related guides for those tasks.

Moving into or out of San Jose

California taxes worldwide income while you are a resident and California-source income during nonresidence. Form 540NR is the nonresident/part-year route. A move during the year can leave a California-source filing obligation.

Keep your actual residence and work dates, plus California property or business details. Ask whether the preparation scope includes both states, state credits and any prior-year carryovers.
