Understanding California Paycheck Taxes

Navigating paycheck taxes in California involves understanding federal, state, and sometimes local tax obligations that impact your take-home pay. This guide provides a clear overview of how these taxes are calculated, key factors affecting your withholdings, and official resources to ensure compliance and accuracy.

Federal Income Tax

Federal income tax is withheld from your paycheck based on your gross income, filing status, and allowances claimed on your Form W-4. The Internal Revenue Service (IRS) uses a progressive tax system, meaning higher earnings are taxed at higher rates. For 2025, tax brackets range from 10% to 37%, depending on your taxable income. Your employer calculates withholdings using the information you provide on Form W-4, which includes your marital status, dependents, and any additional tax you want withheld. To estimate federal withholdings accurately, refer to the IRS Tax Withholding Estimator.

California State Income Tax

California imposes a state income tax, which is also progressive, with rates ranging from 1% to for 2025, depending on your income and filing status. The California Franchise Tax Board (FTB) oversees these withholdings. Your employer uses the DE 4 form, California’s equivalent of the W-4, to determine state withholdings. This form allows you to adjust for state-specific allowances or additional withholdings. California’s top rate of applies to high earners, including an additional 1% Mental Health Services Tax for taxable income above $1 million. To understand your state tax liability, consult the FTB’s tax rate schedules.

Social Security and Medicare Taxes

Federal payroll taxes include Social Security and Medicare, collectively known as FICA taxes. For 2025, Social Security tax is on earnings up to $168,600, and Medicare tax is on all earnings, with an additional for wages exceeding $200,000 (single filers) or $250,000 (married filing jointly). These rates are outlined by the Social Security Administration. Self-employed individuals pay both the employee and employer portions, totaling for Social Security and for Medicare, as per IRS guidelines.

California State Disability Insurance (SDI) and Other Deductions

California requires contributions to State Disability Insurance (SDI), which provides short-term benefits for non-work-related disabilities or pregnancy. For 2025, the SDI withholding rate is on wages up to $161,215, with a maximum contribution of $1, according to the Employment Development Department (EDD). Some employees may also contribute to the Paid Family Leave (PFL) program, which is funded through SDI. Unlike other states, California does not have local income taxes in most areas, but other deductions like health insurance or retirement contributions may reduce your take-home pay.

How Paycheck Taxes Are Calculated

Your employer calculates taxes based on your gross pay per period (weekly, biweekly, or monthly). The process involves:

  • Determining federal income tax using IRS withholding tables and your W-4 details.
  • Calculating state income tax using FTB tables and DE 4 information.
  • Applying FICA taxes (Social Security and Medicare) at fixed rates.
  • Withholding SDI at the state-mandated rate.

Bonuses, overtime, or irregular income may be taxed at supplemental rates: 22% for federal and for California, per FTB guidelines. To preview your net pay, use official tools like the EDD’s payroll tax calculator resources or the IRS estimator.

Factors Affecting Your Withholdings

Several factors influence your paycheck deductions:

  • Filing Status: Single, married filing jointly, or head of household impacts tax brackets.
  • Dependents: Claiming dependents reduces taxable income.
  • Multiple Jobs: Holding multiple jobs requires adjusting withholdings to avoid underpayment.
  • Additional Income: Interest, dividends, or freelance income may require extra withholdings.

Review your W-4 and DE 4 annually or after major life events (marriage, childbirth, or job changes) to ensure accurate withholdings.
