New hire paperwork and compliance for California

Hiring in California comes with the longest new-hire paperwork stack in the country, and the cost of missing a form isn't abstract: wage claims, EDD penalties, and notices that carry statutory damages per employee. This guide is the complete 2026 checklist — every form, notice, and pamphlet with its deadline and source, current as of July 2026 — including a brand-new notice requirement most employers haven't heard of yet.

Getting the foundation right pays beyond compliance. According to the Intuit QuickBooks Small Business Financing Report, small businesses using business financing are nearly twice as likely to be in an active growth phase, and clean payroll records are the first thing every lender and every audit asks for.

If you're hiring your first California employee, start with the registration section: two obligations exist before day one. If you already run a team, the checklist table and the 2026 changes section are your audit. And if you're onboarding a remote worker who lives in California, the rules follow the worker, not your address.

By the end, you'll have every required document mapped to its deadline, the registration steps that come first, and the 2026 changes to fold into your onboarding packet. Start with the full checklist.

What new hire paperwork is required in California?

Paperwork is one of the most important (and most dreaded) parts of hiring a new employee. Collecting all the right documents is nerve-wracking because you know how important it is to get it right.

And in California, the stack of new hire paperwork is a little thicker compared to other states.

IMPORTANT: Before collecting any personal information, employers must provide applicants and employees with a copy of the California Consumer Privacy Act.

The 2026 California new-hire paperwork checklist

Every legally required form, notice, and pamphlet for a standard California hire, verified against official sources in July 2026. Bookmark it — we update the rows as forms change.

Two rows deserve a flag. The Workplace Know Your Rights notice is new: SB 294 requires it for every new hire starting February 1, 2026, using the Labor Commissioner’s model notice, and most onboarding packets built before this year don’t have it. And the I-9 changed editions: from August 1, 2026, only forms showing the 05/31/2027 expiration date in the top-right corner are valid, so check the packet you’re photocopying from.

Required federal onboarding paperwork

I-9 employment verification form

The Form I-9 is mandatory for all new hires in the United States in order to verify their identity and authorization to work in the US. You, the employer, have three business days to complete Section 1 (employee information) after your new hire starts working. They then have three business days to complete Section 2 (providing documents proving work authorization). The U.S. Citizenship and Immigration Services (USCIS) offers a helpful I-9 Employment Eligibility Verification guide with a list of acceptable documents.

• Important note: Always retain copies of completed I-9 forms for at least three years (or one year after employment ends, whichever is later). Failure to properly complete and maintain I-9 forms can result in significant fines for employers.

W-4 federal tax withholding form

The W-4, which is also federally required for all U.S. workers, determines how much federal income tax is withheld from your employee's paychecks. The information the employee provides dictates the number of allowances they claim, impacting their take-home pay. The Internal Revenue Service (IRS) offers a W-4 instructions and publications page for further details.

The deadlines that matter: the employee completes I-9 Section 1 no later than the first day of work, and you complete Section 2 within 3 business days of the start date, with the supporting documents examined in person or under the remote procedures if you use E-Verify. On that subject, a California wrinkle: E-Verify is optional for private California employers, and state law restricts using it on existing employees or pre-offer applicants. The W-4 is collected at hire, before the first paycheck; employees claiming exempt must refile each year by February 15.

Required state onboarding paperwork

Required onboarding forms and pamphlets that are specific to California include:

California employee’s withholding allowance certificate (Form DE-4)

This form is used by employees to specify how much state income tax should be withheld from their paychecks. It works similarly to the federal W-4 form but is specific to California’s state tax regulations. Employers are required to retain this form but do not need to submit it to the state unless requested. However, they must ensure the correct amount of state tax is withheld based on the information provided.

Additional California new hire forms and pamphlets:

• Worker’s Compensation Time of Hire Pamphlet
• Sexual Harassment Pamphlet DFEH-185P
• Paid Family Leave Form DE 2511
• California Family Care and Medical Leave fact sheet
• EDD Disability Insurance Form DE 2515
• Rights of Victims of Domestic Violence, Sexual Assault and Stalking handout
• Health Insurance Marketplace Coverage Options Form OMB No. 1210-0149
• Wage and Employment Notice to Employees Form DLSE-NTE (for non-exempt employees only)
• Work Permit for Minors (if applicable) ( CDE Form B1-4)

You should consider having the employee verify they received and reviewed any handouts and papers that don’t require a signature. This could be one extra signed form that lists all the documentation you gave them so they can check off each one, sign the form, then store it in their employee file.

Three corrections and additions worth building into the packet. First, the DE 4 is required for every California new hire, not just those whose state withholding differs from federal; without a completed DE 4, you withhold as single with zero allowances. Second, the Wage Theft Prevention notice (form DLSE-NTE, revision 11/2023) goes to every nonexempt hire at the time of hire, and the current template already includes the paid-sick-leave section (5 days or 40 hours per year) and the emergency-or-disaster disclosure added in 2024; if any noticed term changes later, you re-notice within 7 days. Third, two notices most packets miss: the Survivors of Violence rights notice, which moved to Government Code 12945.8 with a Civil Rights Department model published in July 2025 and is required at hire, annually, and on request, and the new SB 294 Know Your Rights notice covered in the 2026 changes below.

California new hire reporting requirements

State and federal law requires all employers (public and private) to report newly hired, rehired, or returning employees within 20 days of their start date. This form can be completed electronically through the California Employee Development Department website, faxed, or mailed to the address listed.

The specifics: file form DE 34 with the EDD’s New Employee Registry within 20 days of the start-of-work date, including rehires, through e-Services for Business. This assumes you're already registered as an employer, which is the step below.

Before day one: registering as a California employer

Two obligations exist before your new hire fills out anything.

First, employer registration: you must register with the EDD within 15 days of paying more than $100 in wages in a calendar quarter, through e-Services for Business (the paper DE 1 route takes weeks longer). Registration gets you the employer account number that every payroll filing, including the DE 34 above, hangs off.

Second, workers' compensation: California requires coverage from your very first employee, even part-time, under Labor Code 3700, and operating without it is a misdemeanor with penalties that can reach $100,000 plus a stop order that closes the business until coverage exists. Say you're a Pasadena bakery bringing on one weekend counter helper: registration and a workers' comp policy both apply before that first Saturday shift, at any hours count.

And confirm your wage floor: the 2026 state minimum is $16.90 per hour, higher in many cities and in fast food and health care, and the exempt salary floor is $70,304 per year. Below that salary, the title doesn't matter: overtime rules apply.

Hiring out-of-state and remote workers into California

The rule that decides everything: California employment law generally follows where the work is performed, not where the company sits. Hire a remote developer who works from her apartment in San Diego and the full stack applies — EDD registration, DE 34 reporting, the DE 4, the notices and pamphlets above, plus California's daily overtime and break rules — even if your company has no other California presence. In the reverse direction, a California company hiring someone who works remotely from Texas or Ohio generally follows that state's wage-and-hour rules for that employee. Multi-state situations have edge cases, so when a hire splits time across states, that's a question for an employment attorney before the offer letter, not after.

What changed for California hiring in 2026

Three changes to fold into the onboarding packet this year:

1. The Workplace Know Your Rights Act (SB 294) took effect February 1, 2026: every employer must give the Labor Commissioner’s model notice to each new hire at hire and to all employees annually, and must offer each employee the chance to designate an emergency contact for arrest or detention notification. This is a stand-alone written notice, not a poster.
2. The I-9 edition cutover: from August 1, 2026, only forms showing the 05/31/2027 expiration are valid. Purge older packets.
3. The 2026 numbers moved: minimum wage $16.90, exempt salary floor $70,304, and the computer-professional rate $58.85 an hour.

Top priorities on day 1

When your new hire shows up for their first day, there’s usually a mix of legal formalities and getting to know people and places. But before they can officially start work, HR needs to make sure they fill out all the necessary paperwork.

Paperwork and policies

Most of the required new hire paperwork in California can be filled out on the employee’s first day. The exception is the Disability Insurance Provisions (Form DE 2515), which must be provided to the employee within five days of hiring.

New hire orientation is also a good time to provide any company-specific documents before your employee begins work. Additional policies may include:

• Non-disclosure agreement (NDA): If your company deals with confidential information, an NDA might be required.
• Benefits enrollment forms: If you offer health insurance, retirement plans, or other benefits, new hires will need to choose their coverage options.
• Direct deposit authorization: This form allows for electronic payroll deposits into the employee's bank account.
• State and local requirements: Depending on your industry or location within California, there may be additional state or local requirements for new hires. Research any specific regulations that might apply to your business.
• Employee handbook: Provide your new hire with a copy of your employee handbook, which outlines company policies, procedures, and benefits. This serves as a valuable resource for them throughout their employment.
• Background checks: While not mandatory in California, some employers choose to conduct background checks on new hires. If this aligns with your company's policy, ensure you comply with all federal and state laws regarding background checks.

How to comply with California state employment standards

California employers need to set the stage for a compliant workplace by ensuring all required labor law posters and notices are available in prominent places. Each poster covers an important employment-related topic, such as labor laws, wages, workplace accidents, and more.

You should regularly check to make sure the following posters are displayed and available to your employees at all times:

• Workplace Discrimination and Harassment Poster
• Notice to Employees — Injuries Caused by Work
• Whistleblower Notice
• Unemployment Insurance Benefits Notice
• Paid Sick Leave Poster
• Payday Notice
• Emergency Phone Numbers
• Minimum Wage Poster
• Safety and Health Protection on the Job Poster

There are a number of other posters that are required by California state law, depending on the industry or type of employer.

In addition, California workplaces will need to display all federally required posters and notices. These include:

• Your Rights Under USERRA
• Families First Coronavirus Response Act Paid Leave Notice
• Family Medical Leave Act of 1993 (FMLA)
• Employee Polygraph Protection Act
• FLSA Federal Minimum Wage Poster
• OSHA Job Safety & Health Protection Poster
• Equal Employment Opportunity Poster

Additional posters may be federally recommended or required depending on industry. See a complete list of required federal and California employment posters here.

How QuickBooks helps with California hiring and onboarding

California onboarding is a dozen documents with four different deadlines, and the penalty for missing one lands per employee. QuickBooks Payroll handles the mechanics that trip teams up: employer registration details in one place, new-hire reporting, California withholding, and the records that prove every form went out on time. Build the packet once from the checklist above, and let payroll keep the deadlines.
