Workers’ Compensation Requirements by State for Employers

Workers’ compensation requirements vary by state, and the state where employees perform the job sets the rules.

That makes things complicated when a business grows and crosses state lines.

Take a roofing contractor who lands a job a few states away and hires extra crew members to complete that project. Before anyone even climbs a ladder, the owner needs to know which state’s requirements apply and how they’ll impact the new hires.

This article helps business owners understand where they can find each state’s official requirements and what impacts coverage. It also provides you with a simple checklist to run before any project begins.

Where Can Employers Find Official Workers' Comp Requirements by State?

Workers’ compensation is mainly a state responsibility. No federal law requires private employers to carry it. Instead, each state has its own workers’ comp laws and sets its own rules for coverage, exemptions, and claims.

The federal government runs workers’ comp programs only for specific groups. Those groups include:

• Federal employees
• Longshore and harbor workers
• Coal miners with black lung disease
• Certain other energy workers

A business with crews working on docks or navigable waters may need coverage under the federal Longshore and Harbor Workers’ Compensation Act on top of state requirements.

The U.S. Department of Labor (DoL) provides a convenient directory of state workers' compensation agencies with an interactive map. You need only click the state where their team will work to find each agency's website and contact details.

While the DoL website won't summarize each state's rules for employers, it makes it easy to find the correct agency. On the agency's site employer section, it'll usually cover:

• Employer coverage requirements
• Exemptions
• Guidance on contractors and subcontractors
• Rules for out-of-state work

If the published guidance doesn't cover a specific situation, a simple call to the agency should get you the information you need. These agencies have experienced all sorts of unique circumstances and can provide expert guidance on moving forward.

Remember that requirements change. Even if a business owner has previously operated in another state, it's critical to confirm the current rules with the state agency before starting any work.

What Determines if a Business Needs Workers' Comp Coverage?

That obligation depends on how the state's rules apply to a business' workforce, industry, ownership structure, and where the work happens. Each state answers those questions its own way.

Number of Employees and Type of Work

States set different employee thresholds when it comes to coverage. Business owners need to know how their state counts employees. Many states count part-time and seasonal workers, and some count owners or officers, too.

But headcount alone doesn't always determine coverage requirements. The same two-person business can need coverage in one industry but not another, even in the same state.

Owners, Officers, and Exemptions

An owner exemption must answer three questions:

• Is the owner eligible to apply?
• Is the exemption approved and active?
• Does the business still have to cover everyone else?

An exemption covers only the person who holds it. It doesn't exempt the company or its employees. Business owners need to check each state's rules for who qualifies, how to apply, and when to renew.

For example, under Florida's construction exemption requirements, an officer must own at least 10% of the company, and that company can exempt no more than three officers. Those conditions apply only to the individual applicant(s). They don't change the company's coverage requirements for its team.

Employees, Contractors, and Subcontractors

A job title, contract, or 1099 doesn't determine if an employee needs work comp coverage. The state's worker-status rules do. Business owners need to review the state agency's guidelines on employees and independent contractors first.

Further to that, worker status and class codes answer different questions. Status decides whether the business must cover the person. The class code describes the work the person does.

Subcontractors bring their own risk, too. In many states, if a sub has no coverage, the sub's workers can fall on the contractor they report to. Before a sub starts work, the owner needs proof of coverage or a valid exemption.

Working in More Than One State

Whenever a business owner accepts any out-of-state projects, that should prompt an immediate review of coverage long before the crew ever leaves for the jobsite. That means checking the current coverage rules from the state's agency and what coverage is currently in place.

A well-informed business owner should ask:

• Does the current coverage apply to temporary work in that state?
• What changes if the work there turns into ongoing operations?
• What documentation will the state require?
• Does the business need additional coverage for that state?

How State Requirements Differ for Employers

As mentioned, the industry that an employee works in can change coverage requirements, even in the same state. Florida makes this very clear. Here's how Florida's employer coverage requirements compare:

For example, a framing contractor with two employees needs coverage in Florida. A two-person retail shop does not. Both still need to apply Florida's rules on counting employees, owner exemptions, and the state's other provisions.

And when it comes to officers of Florida companies, the 10% ownership figure determines whether that officer can apply for an exemption or not. It doesn't decide whether the company needs coverage.

In all practicality, owners must check the requirements for their own industry and business structure. A general headcount rule isn't sufficient.

How to Check Workers' Comp Requirements Before Work Begins

Business owners can run through four steps before a new hire, sub, or job starts. Each one takes minutes and can prevent headaches later on.

1. Identify where employees will work. This includes regular job sites and any planned projects in other states.
   
   
2. Locate each state's official employer guidance. The DoL directory linked above provides each state's agency.
   
   
3. Review employee counts, ownership, exemptions, and contractor rules. Current workforce numbers matter here, and any claimed exemption needs to be validated.
   
   
4. Confirm coverage and required documentation. The owner walks the provider and the state agency through the planned work, then checks coverage, certificates, required notices, and reporting rules before the first day on the jobsite.

State Coverage Lookup Tools

Several states offer a public search that shows whether a business has workers' comp coverage on file. These tools show existing coverage. They don't show what coverage a business is required to carry.

Here are just a few examples.

• California workers' comp coverage inquiry: run by the WCIRB, the state's rating bureau. Results can lag 60 days behind recent policy changes.
• Florida Proof of Coverage search: also shows construction exemptions.
• Georgia employer coverage verification
• North Carolina insurance coverage search

These databases are especially helpful at a few key moments.

Before a subcontractor starts any work, you can easily confirm if the sub has active coverage. If it’s lapsed, the sub’s workers can become the general contractor’s responsibility. You can also check if your policy shows up on file in the state where your crew will work. And in states that list exemptions, such as Florida, the search shows you if that exemption is current.

Once again, these databases can lag behind by up to 60 days. Any search result should not be treated as final proof. Requesting a certificate of insurance from your subcontractors is a best practice in most cases.

FAQs About State Workers' Comp Requirements

Does a Business with One Employee Need Workers' Comp Coverage?

It can. In some states and industries, one employee triggers the requirement, so business owners need to check how their state counts employees by industry.

Does an Owner's Exemption Cover the Entire Company?

No. An exemption covers only the owner who holds it. The business still has to cover its other employees under the state's rules.

Does a Business Owner Need to Check Another State's Requirements When a Crew Travels There?

Yes. The owner needs to review the requirements where the crew will work and have the provider confirm how current coverage applies before the job starts.

Where Can Business Owners Verify Workers' Comp Coverage or an Exemption?

Coverage and exemption searches can be separate or even lag, so the state agency should be the starting point.

Confirm State Workers' Comp Requirements Before Work Begins

Always find official state guidance, check how it applies to your business, and confirm coverage before work starts. A new hire can change what's required. So can new duties for an existing employee, a new sub, or a job across state lines.

Before contacting a state agency or a coverage provider, you should have this information ready:

• Every state where employees will work, with project start dates and how long each job will last
  
  
• Current headcount, including part-time, seasonal, and newly hired workers
  
  
• Each worker’s job duties, since duties drive class codes
  
  
• Owners and officers, with ownership percentages and any active exemptions
  
  
• Subcontractors on the job, with their certificates of insurance or exemption proof
  
  
• Current policy details: carrier, policy number, effective dates, and the states listed on the policy

With those details in hand, the conversation moves faster and the answers are more accurate. The same questions come up whether a business works with a traditional carrier or with a PEO that bundles workers’ compensation coverage with payroll and claims support.
