Expanding outside California can create new opportunities for your business. But hiring your first employee in another state can also create workers’ compensation, payroll, tax, and compliance responsibilities you did not have before.
For contractors, manufacturers, restaurants, and other blue-collar businesses, the safest approach is to address these requirements before employees begin working in the new state.
Why Multi-State Workers Compensation Matters Before You Expand
California requires employers with one or more employees to maintain workers’ compensation coverage. But expanding outside California adds another question: Which state’s workers’ compensation rules apply to the employee?
The answer can depend on where the employee was hired, where they regularly work, where an injury happens, and the laws of the other state.
California Labor Code Section 3600.5 is especially important. In certain situations, an employee hired or regularly working in California may still be entitled to California workers’ compensation benefits after being injured while working outside the state.
That means simply sending a California employee to another state does not automatically remove California from the picture.
Before expansion, ask your insurance professional whether your current policy covers the new state and whether you need multi state workers compensation insurance.
How Does Workers Compensation Multiple States Coverage Work?
A workers’ compensation policy is not automatically a nationwide solution. Insurance requirements, benefits, classifications, and employer responsibilities can differ by state.
Imagine a California construction company wins a long-term project in Arizona. It sends five California employees to the job and hires eight additional employees locally.
The company now needs to determine how its existing coverage applies to employees temporarily working outside California and what Arizona requires for employees regularly working there.
A similar issue can arise when a restaurant group opens its first Nevada location or a California manufacturer establishes a warehouse in Texas.
This is why workers compensation multiple states planning should happen before the first shift, delivery, installation, or jobsite assignment.
What About Workers Comp For Out Of State Employees?
Employee location matters.
California employers should identify whether someone will temporarily travel outside California, permanently relocate, work remotely in another state, or be hired specifically for an out-of-state location.
Those situations can produce different insurance and compliance requirements.
For example, a California contractor sending a crew to Nevada for a short project presents a different situation from establishing a permanent Nevada branch and hiring workers who live and work there.
This distinction matters because workers comp for out of state employees can involve more than adding another address to an existing policy. The insurer may need to review payroll, job classifications, employee duties, work locations, and the states where operations will occur.
Don’t Forget Multi-State Payroll And Taxes
Workers’ compensation is only one part of expansion.
A California employer with out of state employees should also determine where wages must be reported and where unemployment insurance, state income tax withholding, and other payroll obligations apply.
California’s Employment Development Department specifically provides guidance for multi-state employment. California employers generally must register with the EDD within 15 days after paying more than $100 in wages in a calendar quarter, and employers operating across states can face additional reporting requirements based on where employees perform their work.
Multi-state employers may also elect, under federal rules, to report all new hires electronically to one state where they have employees after completing the required federal registration.
Before expanding, review:
- Workers’ compensation coverage in each state
- State employer and payroll registrations
- Income tax withholding requirements
- Unemployment insurance obligations
- Employee work locations and classifications
- New-hire reporting
- Required workplace notices
- State-specific wage and employment rules
Getting these questions answered before payroll begins is much easier than correcting registrations, taxes, or insurance coverage afterward.
Why Blue-Collar Employers Need To Be Especially Careful
For businesses with physical jobs, getting workers’ compensation right is particularly important.
California reported 679,537 occupational injuries and illnesses in 2024, while employers paid an estimated $23.2 billion in workers’ compensation system costs.
Consider a California manufacturer opening a second facility outside the state. Its production workers, warehouse employees, drivers, and office staff may have different classifications and risks. Accurate employee duties, payroll, and locations help insurers determine appropriate coverage and pricing.
The same principle applies to contractors, restaurants, trucking-related businesses, warehouses, and other blue-collar companies.
A Pre-Expansion Checklist For California Employers
Before your first employee starts working in another state, answer five questions:
1. Where will employees actually work? Identify permanent locations, temporary projects, remote employees, and traveling crews.
2. Does your current workers’ comp policy cover that state? Never assume it does.
3. Do you need employer registration there? Review payroll, unemployment, tax, and new-hire requirements.
4. Have payroll and job classifications been updated? Your insurer and payroll provider need accurate information about where employees work and what they do.
5. Are state-specific labor requirements covered? Check wage rules, workplace notices, leave requirements, safety obligations, and other employer responsibilities before operations begin.
