What payroll deductions are employers required to withhold?

California Payroll Tax Deductions Employers Must Withhold

In California, employers are required to withhold specific payroll deductions from employee wages to comply with state and federal regulations. Understanding these deductions is essential for accurate payroll processing and maintaining compliance.

Mandatory Payroll Deductions in California

• Federal Income Tax: Employers must withhold federal income tax based on the employee’s Form W-4 and IRS tax tables.
• Social Security Tax: Withhold 6.2% of wages up to the annual wage base limit. Employers must also match this amount.
• Medicare Tax: Withhold 1.45% of all wages. Additional Medicare tax of 0.9% applies to wages above the IRS threshold, withheld only from employees.
• California State Income Tax: Employers withhold state income tax using the employee’s Form DE 4 and California withholding schedules.
• California State Disability Insurance (SDI): Withhold 1.1% of wages up to the annual SDI wage limit. This covers disability and Paid Family Leave benefits.

Additional Considerations for Employers

• Unemployment Insurance (UI) and Employment Training Tax (ETT): These are employer-paid taxes and are not withheld from employee wages but must be factored into payroll operations.
• Local Taxes: California generally does not have local payroll taxes, but employers should verify based on city or county requirements.
• Voluntary Deductions: Employers may also withhold voluntary deductions such as retirement contributions, health insurance premiums, or wage garnishments, but these require proper authorization and recordkeeping.

Operational Tips for Managing Payroll Deductions

• Use payroll software that integrates California-specific tax tables and deduction rates to automate withholding calculations.
• Regularly update withholding rates and wage limits as announced by the California Employment Development Department (EDD) and IRS.
• Maintain accurate employee records including Forms W-4 and DE 4 for correct tax withholding.
• Submit withheld taxes and required reports on time to avoid penalties.

As of 2026, staying current with California payroll tax rules and leveraging automation can reduce compliance risks and improve payroll accuracy.
