If you’re running payroll in California, you know the rules can feel overwhelming. The state has some of the strictest laws in the country, and getting them right matters for your team and your business. Employers often struggle with the sheer complexity of staying compliant. One small mistake can mean penalties and disputes.
The State of California enforces daily overtime after eight hours and double time after twelve. It also enforces strict pay date schedules for semi-monthly and monthly payrolls, along with mandatory electronic filing and payment of payroll taxes.
On top of that, employers must register with the Employment Development Department (EDD) soon after they start paying wages. These rules go beyond what many other states require. Getting payroll right protects your team and your company. Miss a payroll tax deadline, and you’re looking at a 15 percent penalty plus interest, not something any business owner wants to deal with
Late final pay can lead to waiting time penalties of up to thirty days of wages. This guide shows a step-by-step path to set up payroll in California. You will see the legal, administrative, and strategic actions that keep you compliant and efficient.
Understand California Payroll Laws and Requirements
Payroll in California comes with more rules than in most other states. Employers are expected to understand and follow them to stay compliant and protect their workforce. Below are the main laws that make California stand out:
Minimum Wage
California sets a higher minimum wage than the federal rate, which is $7.25 per hour. Some cities like San Francisco and Los Angeles enforce even higher local rates. As of 2025, the statewide minimum wage is $16.50 per hour, but local ordinances can raise that floor further.
Pay Frequency
The businesses must pay employees at least twice per month, on regular, designated paydays. Wages earned between the 1st and 15th must be paid no later than the 26th of that month, while wages earned between the 16th and the end of the month must be paid no later than the 10th of the following month. This is stricter than many other states that only require monthly or semi-monthly pay.
Overtime Rules
Think paying overtime only kicks in after 40 hours a week? In California, the bar is set much lower. Employees in California earn overtime pay at one and a half times their regular rate after working more than 8 hours in a single day, and double their regular rate after 12 hours in a day. They also qualify for overtime if they work more than 40 hours in a week. Federal law, by contrast, only requires overtime after 40 hours in a week, which makes California’s rule much stricter.
Meal and Rest Breaks
The California employees must receive a 30-minute meal break if they work more than 5 hours, and a second meal break if they work more than 12 hours. They also earn a 10-minute rest break for every 4 hours worked. Skip a required meal or rest break, and it costs you an extra hour of pay per day. The state takes employee breaks seriously.
Payroll Records
Businesses must maintain detailed payroll records, including hours worked, pay rates, deductions, and net wages. These records must be kept for at least three years, and employees have the right to request access.
Wage Statement (Paystub) Requirements in California
When an employee resigns or is terminated in California, the employer must issue the final paycheck without delay. If payment is late, the employer may be liable for a waiting time penalty equal to the employee’s daily wage for each day the paycheck is withheld, up to a maximum of 30 days. Failure to provide accurate paystubs can trigger lawsuits under California’s Private Attorneys General Act (PAGA), exposing employers to significant penalties. Even small errors like missing the employer’s address or not breaking out overtime separately can create compliance risks.
As payroll complexities grow, businesses need more than just accuracy; they need a reliable, compliant, and scalable solution.
Employers must provide the following information on each wage statement:
Gross wages earned
Total hours worked (for non-exempt employees)
All deductions (taxes, benefits, garnishments, etc.)
Net wages earned
Pay period dates (start and end)
Employee’s name and ID number (last 4 digits of SSN or employee number)
Employer’s legal name and address
Hourly rates and hours worked at each rate (regular, overtime, double time)
Piece-rate information (if applicable)
Expert Advice: Use software that automatically applies California’s rules. Manual calculations increase the risk of errors, especially with overtime and city-specific laws.
Step-by-Step: How to Set Up Payroll in California
Setting up payroll involves a series of legal and administrative tasks that ensure employees are paid correctly and taxes are handled on time. Each step builds the foundation for compliance.
Step 1: Apply for an Employer Identification Number (EIN)
An Employer Identification Number, or EIN, is a unique nine-digit number issued by the Internal Revenue Service. Every business that hires employees must have an EIN to report taxes and other documents to the federal government. It acts like a Social Security number for a company.
How to Apply for an EIN
The IRS allows businesses to apply for an EIN online, by fax, mail, or phone (phone is only for international applicants). The online application is the fastest, and once submitted, the EIN is issued immediately.
Note:If you are switching your entity type or ownership structure, you may require a new EIN. Check IRS rules to avoid compliance gaps.
Step 2: Register with the California Employment Development Department (EDD)
This step is a critical part of California payroll setup, as it ensures your business can handle unemployment insurance, disability insurance, and payroll taxes properly.
Once you have your EIN, the next step is registering your business with the California Employment Development Department (EDD). This registration is mandatory for all employers who pay wages, as it allows the state to track unemployment insurance, disability insurance, and payroll taxes.
Identify the first payroll date and the expected number of employees.
After processing, EDD issues a state employer account number used for all tax filings.
Update for Business Changes: For modifications like new locations, additional employees, or ownership shifts, they must be reported to EDD promptly to stay compliant.
Step 3: Collect Employee Payroll Documentation
Before paying employees, you must collect all required documentation to ensure proper tax withholding, eligibility verification, and compliance with California law.
Key Documents to Collect
Form W-4 (Federal Withholding Certificate): Determines federal income tax withholding based on the employee’s filing status and allowances.
Form DE 4 (California Employee Withholding Allowance Certificate): Determines state income tax withholding. California requires this alongside the federal W-4.
Form I-9 (Employment Eligibility Verification): Confirms employee eligibility to work in the U.S. and requires acceptable identity and work authorization documents.
Direct Deposit Authorization: If employees opt for direct deposit, collect a signed authorization form with bank routing and account numbers.
Employee Agreements or Contracts: Include any agreements regarding wages, overtime, or special allowances. Keeping these on file protects the employer in case of disputes.
Step 4: Choose a Payroll Schedule and Frequency
Selecting a payroll schedule is essential for both compliance and employee satisfaction. California law sets minimum standards, but you can choose a schedule that fits your business operations.
Common Payroll Schedules in California
Weekly: Employees are paid once per week, often on a consistent weekday.
Biweekly: Employees are paid every two weeks, resulting in 26 paychecks per year.
Semi-monthly: Employees are paid twice per month, often on the 15th and last day of the month.
Monthly: Employees are paid once per month. Mostly used for salaried employees.
Step 5: Select a Payroll System or Provider
Choosing the right provider is central to California payroll compliance since generic software may not account for overtime, meal breaks, or city-specific rules.
Payroll Provider Options
Manual Payroll: Manual payroll works if you’ve got two or three people. Beyond that, it’s a headache waiting to happen. It requires careful calculation of gross pay, taxes, deductions, and overtime. High risk of error and compliance issues.
Payroll Software: Automates calculations, tax filing, and reporting. Many solutions are California-compliant and can handle city-specific rules, overtime, and benefits.
Outsourced Payroll Services: A third-party provider manages the entire payroll process, including tax deposits, finance and accounting services, and compliance updates. Best for businesses that want to reduce administrative burden.
So what happens if your payroll system isn’t set up to handle split shifts or daily overtime? That’s where errors creep in, and fines follow.
Expert tip: Choose a system or provider that explicitly handles all California requirements automatically, including end-to-end payroll compliance and reporting. Relying on generic payroll software may lead to miscalculations and costly penalties.
Step 6: Calculate Gross Pay, Taxes, and Deductions
Accurately calculating payroll is one of the most critical steps. Miss one payroll deadline in California, and the penalties can stack up fast. That’s why many call it the toughest state in the country for payroll compliance.
Calculating Gross Pay
Gross pay is the total amount earned by an employee before any deductions. This includes:
Regular wages or salary
Overtime pay
Bonuses and commissions
Paid time off
Withholding Taxes
After gross pay is calculated, you must deduct the correct amounts for:
Federal income tax is based on the employee’s W-4.
Social Security and Medicare (FICA) standard rates apply.
State income tax based on the DE 4 form in California.
State Disability Insurance (SDI) is mandatory for California employees.
Unemployment insurance contributions: both state (SUI) and federal (FUTA).
Expert tip:Manual calculations increase the risk of errors, especially for California's daily overtime and split shifts. Payroll solutions significantly reduce mistakes.
Step 7: Pay Employees Accurately and On Time
Paying employees correctly and on schedule is crucial in California, where labor laws are strict, and penalties for late or inaccurate payments are significant.
Key Requirements
Pay Frequency: Non-exempt employees must be paid at least twice per month. Exempt employees must be paid at least monthly.
Pay Method: Employers can pay by check, cash, or direct deposit. California law allows direct deposit only if the employee consents in writing.
Accurate Wages: Ensure employees receive the correct gross pay minus accurate deductions and withholdings.
Step 8: File and Remit Payroll Taxes
Filing and remitting payroll taxes is a legal requirement for all employers. California enforces strict deadlines and penalties, so accurate and timely filings are essential.
Key Tax Responsibilities
1. Federal Taxes
Income Tax Withholding: Submit withheld federal income taxes to the IRS.
Social Security and Medicare (FICA): Both employer and employee portions must be deposited.
Federal Unemployment Tax (FUTA): Employer pays annually.
2. California State Taxes
State Income Tax Withholding: Based on DE 4 forms, submit to the California Employment Development Department (EDD).
State Disability Insurance (SDI): Employee contributions must be reported and remitted.
State Unemployment Insurance (SUI): Employer contributions must be filed regularly.
California’s expansive pay equity law applies to employers with 15-plus employees. Covered employers must establish pay scales and pay ranges for each position and furnish that information to job applicants and employees upon request.
