California Payroll: Taxes, Rules, and Compliance for Small Businesses

California payroll laws do not follow a simple payroll playbook. State tax rules, wage and hour laws, and filing requirements often go beyond federal standards, and they do not always line up cleanly. If you run payroll for employees in California, you need to know what applies at the state level and how it affects your process day to day.

This guide covers some of the most common California payroll taxes, wage requirements, and employer responsibilities. Use it to understand the framework, then confirm current rates and rules with the Employment Development Department (EDD) or your payroll tax advisor before you file.

Payroll Taxes in California

What payroll taxes do employers pay in California? The state breaks payroll taxes into four categories. Two are deducted from employee wages — State Personal Income Tax (PIT) and State Disability Insurance (SDI) — and two are paid by the employer: Unemployment Insurance (UI) and Employment Training Tax (ETT). Keeping that distinction straight matters when you are setting up payroll or reviewing what goes where.

Rates, wage bases, and withholding amounts all depend on employee earnings, filing status, and current state thresholds. Most employers rely on payroll systems to handle these calculations in real time. Many payroll platforms automatically calculate SDI and PIT withholding based on current rates, wage levels, and employee elections on Form DE 4 and Form W-4, which cuts down on manual adjustments and keeps payroll consistent.

CA Personal Income Tax (PIT)

California refers to state income tax as Personal Income Tax (PIT) through the Employment Development Department (EDD). Employees pay PIT, and employers withhold it from wages based on California's progressive tax rates, which range from about 1% to 12.3% depending on income and filing status. Employers calculate withholding using the employee's Form DE 4, along with current state tax tables and wage levels. Since 2020, the redesigned federal Form W-4 no longer includes allowances for California PIT purposes, so new hires and any employees changing their withholding must submit both a Form W-4 and a DE 4. If an employee does not provide a properly completed DE 4, employers must withhold California income tax as if the employee were single with zero allowances. Employees who submitted a Form W-4 before 2020 and have not changed their withholding may continue to have PIT calculated based on that earlier form.

Your payroll system should calculate PIT each pay period, apply the correct withholding, and send those funds to the EDD on the required schedule. Employers also report PIT wages and withholding on quarterly returns and annual wage reports. Staying current with rate tables and employee elections keeps withholding accurate and reduces the need for corrections later.

CA State Disability Insurance (SDI)

California State Disability Insurance (SDI) funds Disability Insurance (DI) and Paid Family Leave (PFL), which provide partial wage replacement when employees cannot work due to a non-work-related disability or qualifying family leave. Employees pay SDI through payroll deductions. As of 2026, the contribution rate is 1.3% of wages, and California applies SDI to all wages because the state does not set a wage cap.

Most employees participate in SDI unless they qualify for a limited exemption, such as coverage under an approved voluntary plan. Payroll systems track SDI wages each pay period, calculate the correct deduction, and handle reporting and deposits through the EDD.

SDI plays a separate role from employer-provided leave policies. California requires employers to provide paid sick leave at a rate of at least 1 hour for every 30 hours worked or through a front-loaded grant of at least 40 hours per year. Paid Family Leave benefits, funded through SDI, support employees during qualifying life events.

CA Unemployment Insurance (SUI)

California Unemployment Insurance (UI), often called State Unemployment Insurance (SUI), provides temporary income to eligible workers who lose their jobs through no fault of their own. Employers pay this tax; employees do not contribute. New employers typically start at a 3.4% rate on the first $7,000 of each employee’s annual wages, and the state adjusts experienced employer rates each year based on claims history and other factors.

Payroll systems calculate UI tax based on taxable wages, track each employee’s wage base, and apply the correct employer rate. Employers report UI wages and contributions to the EDD and submit deposits on the required schedule. Many businesses use payroll providers to handle these calculations, filings, and payments, which simplifies the process.

CA Employment Training Tax (ETT)

California Employment Training Tax (ETT) supports state workforce training programs that help employers develop employee skills. Employers pay ETT; employees do not contribute. Employers apply the tax at a rate of 0.1% on the first $7,000 of each employee’s wages each year.

Payroll systems calculate ETT alongside UI, track the wage base, and include ETT amounts in quarterly filings with the EDD. Employers submit ETT deposits through the same process used for UI. Many payroll providers manage these steps together, which keeps filings organized and reduces administrative work.

Minimum Wage in CA

California sets a statewide minimum wage that exceeds the federal rate, and employers must follow the higher standard. As of 2026, the statewide minimum wage is $16.90 per hour. This rate sets the baseline, but it does not always reflect the full picture.

In addition to industry-specific statewide minimum wage rates, many cities and counties, including San Francisco and Los Angeles, enforce local ordinances that require higher minimum wages than the state rate. Employers must follow the highest applicable rate based on where employees perform the work, not where the business operates. That means payroll teams need to track work locations carefully and adjust wages as local rates change.

California Pay Transparency Law

California requires employers to be upfront about pay. If you have 15 or more employees, you need to include a pay range in job postings for any role that someone can perform in California, even if your company sits somewhere else. Current employees can also ask for the pay range tied to their position, and you need to provide it.

Larger employers take on another layer. They must submit an annual pay data reports that breaks down compensation by race, ethnicity, and gender. This law pushes employers to get clear on their pay practices, not just for job postings, but across the organization. Larger employers with 100+ workers through labor contractors as well as employees may be required to submit additional reports.

California Worker Classifications

In California, you don’t get much flexibility when you label someone an independent contractor. The state starts from the opposite position: if you can’t prove the worker meets all parts of the ABC test under AB 5, you treat them as an employee.

To classify someone as an independent contractor, you need all three conditions. The worker must operate independently, perform work outside their core business, and run their own established trade. Miss any one of those, and you’re in employee territory.

This matters for payroll processing. Paying employees requires tax withholding, wage reporting, and compliance with wage-and-hour rules. Paying independent contractors does not. When a business gets this wrong, it usually shows up later as back taxes, overtime claims, penalties, and interest. It’s a classification decision, but it quickly becomes a payroll problem if you don’t get it right up front.

California Workers’ Compensation

Most California employers with at least one employee are required to carry workers’ compensation coverage. In certain circumstances, employers holding specific contracting licenses must carry coverage even if they have no employees. It covers medical care and partial wage replacement when an employee gets hurt or becomes ill because of work. Employees do not pay taxes on these benefits, which sets them apart from regular wages that run through payroll.

Payroll still plays a big role here. Insurers use your payroll data to calculate premiums and review classifications during audits. If you misclassify employees or report wages incorrectly, you can end up with higher premiums, penalties, or coverage issues. Clean payroll records and accurate classifications keep this from turning into a problem.

California Retirement Savings Requirements

If you don’t offer a retirement plan, California expects you to participate in CalSavers. The state requires certain employers to register based on size and deadline, then enroll employees in a Roth IRA program unless they opt out. You don’t contribute as the employer, but you do have to run the process.

That process runs through payroll. You need to set up deductions, apply the correct percentages, and send contributions on time. If you’d rather not manage that piece, look at the CalSavers program requirements or compare other retirement savings plan options in California that may fit your business better.

Setting Up and Filing California Payroll Taxes

Setting up California payroll starts with registration, reporting, and consistent tax filings. Small businesses must report new hires to the Employment Development Department (EDD) within 20 days of the employee’s start date. This requirement helps the state track employment and enforce child support obligations. Payroll systems can automate new hire reporting, track deadlines, and support accurate filings so teams do not have to manage each step manually.

Registering With the California EDD

Before running payroll, employers must register with the EDD to obtain a payroll tax account number.

• Register online through the EDD’s e-Services for Business portal.
• Receive an eight-digit employer payroll tax account number after registration.
• Use this number for all payroll tax filings, deposits, and correspondence.
• If you need to recover your account number, contact the EDD directly or check prior tax filings and official notices.

How To File and Pay California Payroll Taxes

Employers must file payroll tax returns and submit deposits through the EDD based on their assigned schedule.

• File returns using EDD Form DE 9 (Quarterly Contribution Return and Report of Wages) and DE 9C (Quarterly Contribution Return and Report of Wages – Continuation)
• Submit deposits for PIT, SDI, UI, and ETT through the EDD’s e-Services for Business system.
• Follow your assigned deposit schedule (monthly, quarterly, or next-day, depending on payroll size and liability)
• Use a payroll provider like Paychex to manage registrations, calculate liabilities, file returns, and submit payments automatically

California Payroll Tax Due Dates and Deposit Frequencies

California separates two timelines — when employers deposit payroll taxes and when they file quarterly returns. The two are not linked, and employers need to track them independently.

• Quarterly Returns (All Employers): Every employer files Form DE 9 and Form DE 9C quarterly, regardless of their deposit schedule. Returns are due by April 30, July 31, October 31, and January 31.
• Deposit Frequencies (Varies by Employer): The EDD assigns each employer a deposit schedule — Next-Day, Semiweekly, Monthly, or Quarterly — based on the employer's federal deposit schedule and California PIT withholding amounts. The specific thresholds and timing are detailed in the EDD's payroll tax due dates calendar.

Employers must align deposits with their assigned schedule to avoid penalties and interest. Late deposits and late returns are penalized separately.

California Payroll Compliance Rules and Consequences

California requires employers to follow detailed payroll rules that go beyond federal standards, especially for overtime, meal and rest breaks, and final pay. Employers must track hours, pay rates, and timing closely because small errors can lead to wage claims, penalties, or audits. Clear payroll processes and accurate recordkeeping help reduce risk and support compliance.

Overtime

California overtime rules focus on daily hours worked, weekly hours worked, and consecutive workdays. Employers must pay nonexempt employees one and one-half times their regular rate for all hours worked over eight in a single workday, over 40 in a workweek, and for the first eight hours worked on the seventh consecutive day in a workweek. Employers must pay double time, or two times the regular rate, for all hours worked over 12 in a single workday and for all hours worked over eight on the seventh consecutive day.

Certain executive, administrative, and professional employees may qualify for exemptions if they meet salary and duties tests, along with specific industry-based exceptions. Employers must classify employees correctly and track hours accurately to apply overtime rules. Failure to pay overtime correctly can trigger back wages, penalties, and potential lawsuits.

Meals and Breaks

California requires employers to provide both meal and rest breaks and maintain accurate records reflecting compliance. Nonexempt employees who work more than five hours in a day must be provided with the opportunity to take a 30-minute unpaid, off-duty meal period, which must begin no later than the end of the employee’s fifth hour of work. Employees who work more than ten hours must be provided with a second 30-minute meal period no later than the end of the employee’s 10th hour of work..

Employers must authorize and permit paid 10-minute rest breaks for every four hours worked or a major fraction of that time.

Certain industries allow limited exceptions, and employees may waive meal periods under specific conditions. For each workday an employer fails to provide a required meal or rest break, the employer must pay one additional hour of pay at the employee’s regular rate. The premiums are imposed only once per workday regardless of the number of meal or rest breaks the employer did not provide. Payroll systems should be capable of capturing time records that reflect compliance with these requirements.

Payment Frequency and Deadlines

California requires employers to follow strict pay frequency rules and to establish and post regular paydays in advance. Most employees, including nonexempt employees paid on an hourly or salary basis, must be paid at least twice per month. Exempt employees may be paid once per month.

Under a semimonthly schedule, wages earned from the 1st through the 15th must be paid by the 26th of the same month, and wages earned from the 16th through the end of the month must be paid by the 10th of the following month. Employers using weekly or biweekly payroll schedules must pay wages within seven calendar days after the close of the payroll period.

Some exceptions apply depending on industry or collective bargaining agreements. Late or improperly timed wage payments can result in penalties, including wage statement fines, waiting time penalties and other wage-related claims, so payroll timing matters.

Expense Reimbursements

California Labor Code Section 2802 requires employers to reimburse employees for all necessary expenses incurred while performing their job duties. This requirement goes beyond federal law and applies to a wide range of work-related costs.

For example, when an employee uses a personal vehicle for a business errand, the employer must reimburse mileage or actual expenses tied to that use. When a remote employee uses a personal phone or internet plan for work, the employer must reimburse a reasonable portion of those costs, even if the employee maintains an unlimited plan. Employers should set clear reimbursement policies and track payments through payroll or expense systems to maintain consistency.

Final Paychecks

California law sets strict timing and other rules for paying final wages to departing employees. Final wages include all earned pay, including overtime and accrued, unused vacation, and must be accompanied by an accurate, itemized wage statement that lists hours, rates, deductions, and other required details.

Timing depends on how the employment relationship ends:

• If an employer terminates an employee, final pay is due immediately at the time of termination.
• If an employee provides at least 72 hours’ notice of resignation, final pay is due on the employee’s last day.
• If an employee leaves without providing 72 hours’ notice, final pay must be provided within 72 hours. Under the California final pay 72 hours rule, the deadline is measured in calendar time, not business days, and may fall on weekends or holidays.

Limited exceptions may apply in certain industries or under collective bargaining agreements. Employers must comply with California final paycheck law carefully, as delays can trigger the California final paycheck law waiting time penalty. This penalty requires employers to pay the employee’s daily wage for each day the payment remains late, up to 30 days.
