What Is California Payroll Tax?
California payroll tax refers to the collection of state payroll taxes that employers must withhold from employee wages or pay directly to state agencies. These taxes help fund unemployment benefits, disability insurance, workforce development programs, and state income tax obligations.
Unlike federal payroll taxes, California has its own payroll tax system administered by the California Employment Development Department (EDD). Depending on your business size and payroll amount, you'll need to register with the EDD, calculate payroll taxes accurately, file payroll tax reports, and submit payments on time.
Most California employers are responsible for multiple payroll tax requirements, including:
Unemployment Insurance (UI)
Employment Training Tax (ETT)
State Disability Insurance (SDI)
California Personal Income Tax (PIT) withholding
Each tax serves a different purpose, and some are paid entirely by employers while others are withheld from employee wages.
California Payroll Taxes at a Glance
| Payroll Tax | Paid By | Purpose |
|---|---|---|
| Unemployment Insurance (UI) | Employer | Provides temporary income for eligible unemployed workers |
| Employment Training Tax (ETT) | Employer | Supports workforce training initiatives across California |
| State Disability Insurance (SDI) | Employee (through payroll withholding) | Covers disability and paid family leave benefits |
| Personal Income Tax (PIT) | Employee (withheld by employer) | State income tax withheld from employee wages |
Understanding who pays each payroll tax helps employers calculate payroll correctly and avoid reporting errors.
California Employer Payroll Tax Responsibilities
Every employer with workers in California has payroll tax responsibilities beyond simply issuing paychecks. Depending on your business, you'll generally need to:
Register your business with the California Employment Development Department (EDD).
Verify employee withholding information.
Calculate taxable wages.
Withhold applicable payroll taxes.
Pay employer payroll taxes.
File payroll tax returns.
Submit payroll tax deposits before their due dates.
Maintain payroll records for state compliance.
Many businesses automate these tasks using payroll software, reducing the risk of manual errors and missed deadlines.
Types of California Payroll Taxes
California employers typically deal with four primary payroll taxes. Understanding how each one works is essential for accurate payroll processing and compliance.
Unemployment Insurance (UI)
Unemployment Insurance is an employer-funded payroll tax that provides temporary financial assistance to eligible workers who lose their jobs through no fault of their own.
Employers pay this tax directly it is not deducted from employee paychecks.
The amount owed depends on factors such as your employer tax rate and taxable wages. New employers generally begin with an introductory rate, while established businesses receive an experience-based rate determined by their unemployment claims history.
Key Facts
Paid entirely by employers
Calculated on taxable employee wages
Helps fund unemployment benefits
Experience rating affects future tax rates
Must be reported to the EDD
Employers with fewer unemployment claims may qualify for lower unemployment insurance rates over time, making effective workforce management an important long-term cost consideration.
Employment Training Tax (ETT)
Employment Training Tax is another employer-paid payroll tax designed to support workforce development and employee training programs throughout California.
Although the tax amount is relatively small compared to other payroll taxes, employers are still responsible for calculating, reporting, and paying it as part of their payroll tax obligations.
Funds collected through ETT help finance training grants that improve employee skills and strengthen California's workforce.
Why It Matters
Even though ETT represents a small percentage of payroll costs, failing to report or pay it correctly can still lead to compliance issues. Including it in your payroll process ensures complete and accurate reporting.
State Disability Insurance (SDI)
State Disability Insurance (SDI) is funded through payroll deductions from employees. Employers are responsible for withholding the correct amount from employee wages and remitting those funds to the state.
The SDI program provides short-term wage replacement benefits to eligible employees who cannot work because of:
Non-work-related illness
Pregnancy
Injury
Paid Family Leave
Caring for a seriously ill family member
Bonding with a new child
Certain qualifying military family events
Accurate SDI withholding helps employees access benefits when they need them while keeping employers compliant with state payroll regulations.
California Personal Income Tax (PIT)
California employers must also withhold state personal income tax from employee wages.
Unlike employer-paid payroll taxes, Personal Income Tax is deducted directly from employee earnings. The amount withheld depends on factors such as the employee's withholding elections, taxable wages, filing status, and applicable state withholding rules.
Employers are responsible for:
Calculating withholding accurately
Deducting the correct amount each pay period
Reporting withholding to the state
Depositing taxes according to required schedules
Proper income tax withholding reduces the likelihood of employees facing unexpected tax bills when filing their state income tax returns.
Which Payroll Taxes Are Paid by Employers vs Employees?
Understanding who bears the cost of each payroll tax helps prevent payroll mistakes and ensures accurate budgeting.
| Tax | Employer Pays | Employee Pays |
|---|---|---|
| Unemployment Insurance (UI) | YES | NO |
| Employment Training Tax (ETT) | YES | NO |
| State Disability Insurance (SDI) | NO | Through payroll deductions |
| Personal Income Tax (PIT) | NO | Withheld from wages |
While employees ultimately pay SDI and state income tax, employers remain responsible for withholding, reporting, and remitting these amounts accurately.
California Payroll Tax Rates for Employers
Understanding the current California payroll tax rates is essential for calculating payroll accurately and maintaining compliance with state regulations. While some taxes are paid directly by employers, others are withheld from employee wages and remitted to the state.
Keep in mind that certain tax rates and wage limits may change from year to year. Always verify the latest figures before processing payroll.
California Payroll Tax Rates at a Glance
| Payroll Tax | Who Pays | General Rate | Taxable Wage Base |
|---|---|---|---|
| Unemployment Insurance (UI) | Employer | Experience-based | First portion of taxable wages, subject to state limits |
| Employment Training Tax (ETT) | Employer | Fixed state rate | Same taxable wage base as UI |
| State Disability Insurance (SDI) | Employee (withheld by employer) | State-determined withholding rate | Subject to current California rules |
| Personal Income Tax (PIT) | Employee (withheld by employer) | Varies by employee | Based on taxable wages and withholding elections |
Actual rates depend on the applicable tax year and, for some taxes, your employer account history.
Instead of memorizing every rate, employers should focus on using current tax tables, maintaining accurate payroll records, and filing returns on time.
Understanding Taxable Wages
Not every dollar paid to an employee is necessarily taxed in the same way. California payroll taxes often apply to specific categories of taxable wages, and each payroll tax follows its own rules.
Depending on the tax involved, taxable wages may include:
Hourly wages
Salaries
Bonuses
Overtime pay
Commissions
Certain taxable fringe benefits
Some payroll taxes only apply up to an annual wage limit, while others may use different withholding rules. Understanding which earnings are taxable helps reduce calculation errors and prevents underpayment or overpayment.
California Payroll Tax Filing Deadlines
Meeting payroll tax deadlines is just as important as calculating taxes correctly. Late filings or payments can lead to penalties, interest charges, and additional administrative work.
Employers generally file payroll tax reports on a quarterly basis.
Quarterly Filing Schedule
| Reporting Quarter | Filing Deadline |
|---|---|
| January – March | April 30 |
| April – June | July 31 |
| July – September | October 31 |
| October – December | January 31 |
If a deadline falls on a weekend or state holiday, the due date generally moves to the next business day.
Although quarterly returns are common, some employers may be required to deposit withheld taxes more frequently depending on their payroll size and withholding amounts.
Creating payroll reminders or using payroll software can help ensure deadlines are never missed.
How to Register for California Payroll Taxes
Before paying employees, businesses typically need to register with the California Employment Development Department (EDD).
Registration establishes your employer payroll tax account and allows you to report wages, file payroll tax returns, and submit required payments.
Most employers should register shortly after hiring their first employee.
During registration, you'll generally need information such as:
Legal business name
Federal Employer Identification Number (EIN)
Business entity type
Business address
Owner or responsible party information
Date employees first performed services
Estimated payroll information
Once your account is established, you'll receive the information needed to begin filing payroll tax reports.
How to File California Payroll Taxes
Filing payroll taxes involves more than simply making a payment. Employers must accurately report wages, withhold applicable taxes, and submit returns according to state requirements.
A typical payroll tax filing process includes the following steps:
Step 1: Calculate Employee Wages
Determine each employee's gross wages, including regular pay, overtime, bonuses, commissions, and other taxable compensation.
Step 2: Calculate Payroll Taxes
Determine employer payroll taxes and calculate employee withholding based on current tax rules and withholding information.
Step 3: Withhold Employee Taxes
Deduct applicable payroll taxes from employee paychecks before issuing payment.
Step 4: Pay Employer Payroll Taxes
Remit employer-paid payroll taxes according to the required payment schedule.
Step 5: File Payroll Tax Returns
Submit payroll reports showing employee wages, tax withholdings, and employer tax obligations.
