Understanding how your paycheck is taxed in California is essential for effective financial planning. California’s tax system includes federal, state, and sometimes local taxes, which can significantly impact your take-home pay. This guide explains the key components of paycheck taxation in California, how these taxes are calculated, and where to find official resources for accurate information.

Federal Income Tax

Federal income tax is withheld from your paycheck based on your earnings, filing status, and allowances claimed on your IRS Form W- Internal Revenue Service (IRS) uses a progressive tax system, meaning tax rates increase as your income rises. For 2025, federal tax brackets range from 10% to 37%, depending on your taxable income. To calculate federal withholding, employers use the IRS’s withholding tables, which account for your filing status (e.g., single, married filing jointly) and the number of allowances you claim. For detailed guidance, refer to the IRS Publication 15, which outlines employer withholding responsibilities.

California State Income Tax

California has its own state income tax, administered by the Franchise Tax Board (FTB). The state uses a progressive tax system with rates ranging from 1% to for most taxpayers, with an additional 1% surcharge (the Mental Health Services Tax) applied to incomes over $1 million. The exact amount withheld depends on your income, filing status, and allowances claimed on your California Form DE FTB provides tax tables and withholding schedules to help employers calculate the correct amount. Unlike federal taxes, California does not allow certain deductions, such as contributions to Health Savings Accounts (HSAs), so it’s important to review your DE 4 carefully.

Social Security and Medicare Taxes

Your paycheck will also include deductions for Social Security and Medicare, collectively known as FICA taxes. For 2025, the Social Security tax rate is on income up to a wage base limit of $168,600, while Medicare tax is on all wages, with an additional for high earners (incomes above $200,000 for single filers or $250,000 for married couples filing jointly). These rates are set by the IRS, and you can find more details in the IRS Publication 15.

California State Disability Insurance (SDI)

California requires most employees to contribute to State Disability Insurance (SDI), which funds short-term disability and Paid Family Leave benefits. For 2025, the SDI withholding rate is on wages up to a taxable wage limit of $153, deduction is separate from state income tax and is calculated automatically by your employer. The Employment Development Department (EDD) provides official details on SDI rates and withholding.

Local Taxes

While California does not impose local income taxes statewide, certain cities, such as San Francisco, may have payroll expense taxes or other local assessments that indirectly affect employers and, in some cases, employees. Check with your employer or local government for specific requirements in your area.

How Paycheck Taxes Are Calculated

To calculate your paycheck deductions, employers use information from your W-4 (federal) and DE 4 (state) forms, combined with payroll software or tax tables. The process typically involves:

  • Determining your gross pay for the pay period (e.g., weekly, biweekly).
  • Subtracting pre-tax deductions (e.g., 401(k) contributions, health insurance premiums).
  • Applying federal and state withholding tables based on your taxable income, filing status, and allowances.
  • Calculating FICA (Social Security and Medicare) and SDI contributions based on applicable rates and wage limits.

The result is your net pay, or take-home amount. For precise calculations, use a reliable paycheck calculator tailored to California’s tax rules, like the one provided below.

Tips for Managing Your Paycheck Taxes

  • Consider pre-tax deductions, such as retirement contributions or health insurance, to lower your taxable income.
  • Use a paycheck calculator to estimate your net pay and adjust your withholdings if needed.

By understanding these components and leveraging available tools, you can better manage your finances and ensure compliance with California’s tax requirements.
