Workers’ compensation is a state system. Every state writes its own statute, sets its own benefit levels, and decides its own rules about who must be covered and how. That works cleanly when a business operates entirely within one state, and it gets complicated the moment an employee crosses a state line to work.
For a growing number of businesses, that happens routinely. A crew takes a job in the next state, a salesperson covers a multi-state territory, an employee relocates and works remotely from somewhere you have never done business. Each of these can create a coverage question that the policy in your file may not answer.
Why State Lines Matter So Much
An injured worker generally files a claim under a specific state’s workers’ compensation system, and that state’s rules determine the benefits, the medical treatment framework, and the dispute process.
Which state applies is not always obvious. Depending on the jurisdiction, it can turn on where the injury occurred, where the employee was hired, where they principally work, where the employer is based, or some combination. Some states allow an injured worker to choose among more than one that has a legitimate connection.
Because your policy is written state by state, the question that matters is whether the state that ends up governing the claim appears on your policy in the right place.
Reading Item 3 of Your Policy
The information page of a standard workers’ compensation policy contains a section, commonly labeled Item 3, that lists states. It has two parts that are easy to confuse and important to understand.
Part One, sometimes shown as 3.A, lists the states where your policy provides workers’ compensation coverage directly. These are the states you have declared operations in and where payroll is being reported and rated.
Part Three, commonly 3.C, is the other states insurance provision. It lists states where you do not currently have operations but where coverage may extend if you unexpectedly begin work there.
That distinction is the heart of the issue. Other states insurance is designed for the unexpected, not the planned. If you knew you would be operating in a state and did not have it added to 3.A, a carrier may take the position that the other states provision was never intended to respond.
Extraterritorial Provisions and Reciprocity
Most states have extraterritorial provisions allowing an employee temporarily working out of state to remain covered under their home state’s policy for a limited period.
These provisions are not uniform. The permitted duration varies, some states require the work to be genuinely temporary, and some have reciprocity agreements with specific states but not others.
A handful of states are monopolistic, meaning workers’ compensation must be purchased from a state fund rather than a private carrier. Your private policy generally cannot extend coverage into those states at all, and separate arrangements are required for employees working there.
The practical consequence is that a policy that seems to cover a traveling employee may not, and the answer depends on which two states are involved.
Remote Employees Create a Quiet Version of This Problem
Field crews and traveling salespeople make the issue visible. Remote employees make it invisible.
When someone is hired to work from home in a state where your business has no other presence, that state generally becomes their principal place of employment. An injury while working, even at their kitchen table, may fall under that state’s system.
If the state is not listed on your policy, you may face a claim in a jurisdiction where you have no coverage in place. There can also be registration, tax, and posting obligations that come along with having an employee there.
This tends to surface during an audit or a claim rather than at hiring, which is why it is worth handling proactively when someone relocates.
Practical Steps for Employers
Maintain a current list of every state where employees actually live and work, and update it when someone moves. Compare that list against Item 3.A on your policy.
Add states where you have a known, ongoing presence rather than relying on other states insurance to backstop a permanent situation.
Confirm that any monopolistic state where you have workers is handled through the appropriate state fund.
Tell your agent before an employee relocates or before a crew takes an out-of-state job, not after. Adding a state to a policy in advance is routine, while resolving a claim in an unlisted state is not.
Keep records showing where each employee works and how long out-of-state assignments run, since extraterritorial provisions often hinge on duration.
Getting Your Policy to Match Reality
Multi-state workers’ compensation is one of the areas where the details genuinely vary by jurisdiction and change over time, so general guidance only takes you so far. The right answer depends on the specific states involved and how your workforce is distributed.
An independent agent who handles multi-state accounts can review Item 3 against where your people actually are, identify states that should be added, and flag monopolistic state issues before they become claims. If your workforce has spread out over the past few years and the policy has not been revisited, that comparison is worth doing.
