Multi-State Workers’ Compensation Guide

A business can have one office and still employ people in several states. A bookkeeper works from a Washington home, a service crew takes Idaho jobs, and a project manager visits California customers. The business address has not changed, but its workers’ compensation insurance may need a different review.

The question is not simply whether your policy says “workers’ compensation.” It is whether the actual arrangement addresses the right employer, employees, work states and activities—and meets each applicable jurisdiction’s requirements. Remote hiring, repeated travel and permanent expansion can create different obligations.

A home-state policy is not an automatic nationwide solution

Review both the insurance contract and the rules where employees work. State listings, temporary-work exceptions, insurer notification and required acceptance documents each matter. Washington statutory coverage is through L&I industrial insurance or certified self-insurance—not a private Washington workers’ compensation policy.

Start with where each employee actually works

Create a work-location roster, not just a mailing-address list. Record each employee’s regular work state, home-work location if applicable, hiring circumstances, duties, expected travel and the employer entity. Separate permanent home offices from occasional trips and identify recurring assignments across a border.

Headquarters, residence, the place of hiring and the place of injury can all be relevant, but no one fact should be treated as the answer for every state. Washington L&I, for example, evaluates reporting employee by employee and considers where people regularly work, including living and teleworking in Washington. [3]

A payroll platform’s state-tax setting is useful administrative information, not proof of insurance. Likewise, an employee using the same laptop after a move does not mean the insurance issue stayed the same. Make work-location changes part of your hiring and relocation approval process.

Insure Pacific’s licensed-state information helps you identify our service area. An agency license is not confirmation that every insurer writes every operation, and it does not replace a required state-program arrangement.

Item 3.A: the policy’s primary state listing

In the bureau-published standard Workers Compensation and Employers Liability Policy, Item 3.A on the information page identifies the states whose workers’ compensation laws apply to primary coverage. Part One addresses the benefits required by those laws. Review the information page together with the forms and endorsements, not in isolation. [1]

The Indiana Compensation Rating Bureau explains that known or expected operations are properly listed in Item 3.A. Tell your insurer about a planned remote employee, a recurring service territory or an expected branch before relying on coverage. A state that appeared only in an old quote may not be on the issued policy. [2]

Also match the named insured to the business employing the workers. A related LLC, newly acquired company or staffing arrangement should not be assumed to share coverage merely because the owners are the same. Ask how payroll and employees of each entity are included.

Item 3.C: Other States Insurance has conditions

Other States Insurance is not interchangeable with primary listed-state coverage. In the cited standard form, Part Three applies only when a state appears in Item 3.C. It can respond when work begins there after the policy’s effective date, subject to conditions including whether that work is already insured or self-insured. [1]

Do not oversimplify this as coverage only for brief trips. Unmodified voluntary-market Part Three can also address certain newly begun long-term operations after inception. That does not make it appropriate to leave known, expected or already ongoing operations undisclosed in a general other-states listing. [2]

The cited form requires notification “at once” when beginning work in an Item 3.C state and separately addresses work already underway at inception. Those are policy-form conditions, not a universal interstate legal filing deadline. The issued form, endorsements and timing of the actual work control. [1]

Assigned-risk or residual-market policies can use more restrictive Limited Other States Insurance endorsements. A reimbursement provision in a contract is also not proof that the destination state’s insurance requirements have been satisfied. Ask the carrier what it can provide and the regulator what the law requires. [1] [2]

Remote employees: a home office can be a regular work location

A permanent remote employee deserves an onboarding insurance review even if you have no leased office in that state. Disclose the actual address or location through an appropriate channel, duties, work schedule and any regular visits to customers or company facilities. Ask whether the state must be added to the primary listing or requires another arrangement.

Working from home does not automatically eliminate workers’ compensation exposure. Job-related lifting, trips and repetitive-motion problems can arise outside a conventional office. The Hartford’s educational guidance identifies remote-work injuries and state-specific requirements as relevant review topics; a claim still depends on the employment facts and applicable law. [8]

Do not promise that every fall at home is covered, or that an injury outside an agreed schedule is automatically excluded. Describe what happened, what task the employee was doing, the location and the work connection. Let the appropriate insurer, administrator or legal process determine compensability.

Document reasonable workspace expectations, equipment responsibilities, reporting contacts and an approval process for working from a new state. Encourage ergonomic setups and removal of trip hazards. These controls support safer work and clearer records; a remote-work agreement does not override statutory rights.

Traveling crews: one project can involve several coverage arrangements

For installers, contractors and field-service companies, identify the actual project site and crew before bidding or mobilizing. A finite job performed by your established traveling employees is not the same as hiring local workers for an ongoing operation. On the same site, those groups may need different state treatment.

Record expected start and finish dates, where workdays begin and end, the frequency of return visits, employee home bases and whether you maintain facilities in the destination state. Tell your agent if a short project becomes a recurring maintenance contract or if you hire locally while the crew is there.

Our workers’ compensation guide for growing businesses discusses hiring, duties, subcontractors and return-to-work planning. Those operational details remain important when the work crosses a border.

Review job contracts for required insurance evidence and limits before accepting obligations. A customer’s request for a certificate does not determine which state law applies, and a contractual requirement cannot itself expand a policy or create an exemption.

Temporary work and reciprocity are not a universal day-count rule

Extraterritorial coverage generally refers to a home-state arrangement extending to qualifying work elsewhere. Reciprocity can allow a destination state to accept that coverage for eligible temporary work. The actual agreement, employee status, industry restrictions, policy extension and certificate or approval procedures matter. [4] [6]

There is no universal 30-day exemption for out-of-state jobs. A number appearing in one state’s reporting process or an insurance condition should not be applied to another state’s legal requirements. “Temporary” can involve the nature and intent of the operation as well as its expected duration.

The Washington–Oregon agreement considers several factors, including assignment duration, employer intent, the employee’s understanding of the arrangement, facilities and project dates. It also recognizes that a project with Oregon and Washington workers can require arrangements in both states. It is not simply a rule about how long a vehicle stays across the border. [5]

Obtain confirmation before work begins and revisit it if the facts change. An approved finite assignment should not be silently stretched into permanent operations. Keep the current approval, the period it covers and the person responsible for renewals in your project records.

Washington: L&I industrial insurance requires its own review

Washington is a monopolistic state for statutory workers’ compensation. Employers use Washington L&I industrial insurance or qualify as certified self-insured employers. A private carrier’s other-states listing does not create a private Washington statutory policy. Qualifying temporary out-of-state coverage accepted by L&I is a different arrangement. [3]

An Oregon company hiring someone who regularly lives and teleworks in Washington should not describe that employee as a visiting Oregon crew member. L&I identifies that situation as typical of Washington-based employment. The Washington–Oregon agreement also excludes Washington workers of Oregon employers while those workers work in Washington. [3] [5]

For an incoming traveling crew, L&I directs employers to verify actual coverage with their insurer and have the home-state administrator send an extraterritorial coverage certificate where reciprocity applies. L&I’s approval confirmation provides evidence of its acceptance. An ordinary broker certificate is not the same document. [3]

Restrictions vary by reciprocal arrangement. L&I specifically excludes construction work from its Montana and Nevada reciprocity arrangements. Do not copy that restriction onto every other reciprocal agreement, or assume every non-construction visit qualifies. Work type, licensing requirements and employee-specific facts need review. [3]

See our Eastern Washington L&I Industrial Insurance Guide for regional context. Insure Pacific can help organize insurance questions, but Washington reporting and state-program acceptance must be confirmed with the appropriate administrator.

Washington employees working outside Washington

L&I says Washington-based employees remain reportable to its system when they travel, while the destination jurisdiction may also require coverage. Its separate supplemental reporting process has specific approval and reporting conditions and does not apply to work covered by reciprocity. Do not treat its reporting thresholds as a general permission to leave either state unaddressed. [3]

Oregon: distinguish temporary assignments from permanent expansion

Oregon WCD explains that Oregon coverage extends to Oregon workers temporarily employed elsewhere, but another state may require additional coverage before the work starts. Reciprocity is limited to qualifying temporary work and can include restrictions. Contact both the insurer and the destination agency rather than assuming the Oregon policy answers both questions. [4]

For incoming temporary work, Oregon generally requires Oregon coverage unless the employer qualifies through extraterritorial coverage from a reciprocating state. A permanent Oregon location and local hires require Oregon coverage; a company’s out-of-state headquarters does not make its Oregon branch temporary. [4]

A permanent home-work arrangement without a traditional branch can still need analysis. Describe the facts instead of trying to fit every remote employee into a traveling-crew exception. If your company expands its services or footprint, our business-growth insurance review guide helps connect the employment change with the wider insurance program.

Idaho: a temporary-work certificate needs approval

Idaho’s Industrial Commission says eligible out-of-state employers may request extraterritorial coverage through their home-state administrator. The Commission obtains information about Idaho operations and reviews the request case by case. Its guidance requires approval before qualifying temporary out-of-state employees start work in Idaho. [6]

The Commission distinguishes temporary and intermittent work and identifies common reasons a request does not qualify. Principally localized employees, Idaho residents hired specifically for Idaho work, a permanent physical location and certain recurring operations can prevent eligibility. A brief job description alone is not the required approval. [6]

For Idaho employers sending workers elsewhere, the outgoing certificate is not considered valid coverage until the reciprocal state approves it. This is a useful reminder that requesting paperwork and receiving acceptance are separate steps. Our Northern Idaho workers’ compensation guide for growing employers provides additional regional review questions.

California: temporary-work exceptions have actual conditions

California Labor Code 3600.5 illustrates why a state line is not the only relevant fact. It addresses qualifying out-of-state injuries for employees hired or regularly working in California, and separately provides a conditional exemption for employees hired outside California who are temporarily working there. [7]

The general temporary-work provision requires employer-furnished other-state coverage for the California work and reciprocal recognition and exemption conditions. It is not simply permission for anyone with an out-of-state policy to enter California uninsured under its rules. The section’s separate professional-athlete provisions should not be applied to an ordinary service crew. [7]

Before assigning employees, confirm the actual coverage obligation, evidence and insurer arrangement with qualified advisers. A reciprocal relationship elsewhere in the West does not prove the same facts qualify in California. If a project becomes permanent or local hiring begins, request a fresh review.

Employers liability and stop-gap are separate from statutory benefits

In the cited standard policy, Part One pays statutory workers’ compensation benefits. Part Two addresses covered damages the employer legally must pay because of employee bodily injury, subject to its own limits, exclusions and conditions. It is not coverage for every employee lawsuit, and it does not replace the benefit obligation. [1]

When state-fund or monopolistic-state arrangements are involved, ask specifically about employers liability or stop-gap protection for the affected employees. Verify covered states, the employment connection, exclusions, limits and defense terms. Adding a state to Other States Insurance should not be assumed to supply either the required statutory arrangement or a stop-gap endorsement.

Washington DES’s published out-of-state FAQ illustrates how a particular employer’s stop-gap arrangement can have different treatment for different states, including an exclusion for that arrangement’s in-Washington employees. It is an example—not a form applicable to every business. The actual policy or endorsement offered to your company must be reviewed. [9]

Keep employment-practices allegations, employee injury damages and statutory benefits distinct in the broader commercial insurance review. Insurance for discrimination or wrongful termination does not automatically pay work-injury benefits, just as statutory benefits do not insure every employment dispute.

Travel injuries, vehicles and international work need coordination

A traveling employee may drive, stay overnight or combine business duties with personal activities. Record the travel purpose, employer instructions and actual activity when an injury occurs. Commuting, business travel and a personal detour should not be assigned one automatic claim outcome; applicable law and the facts matter.

Review the vehicles separately. Commercial auto insurance addresses vehicle-related liability and other selected auto exposures under its terms; it is not a substitute for required workers’ compensation. Personal vehicles used for work can also raise hired/non-owned auto questions.

If someone plans to work outside the United States, flag that separately before approval. Other States Insurance is not a blanket worldwide employment solution. Local compulsory arrangements, foreign voluntary coverage and travel-related services may need specialized review; do not assume a domestic policy or travel medical card resolves them.

Payroll, subcontractors and renewal records should follow the actual work

Maintain accurate records by employer entity, employee, duties, state and assignment. Ask the insurer how payroll must be allocated and what supporting documents it requires. Do not invent an allocation percentage or shift a field employee into clerical work simply because that produces a lower premium.

A single employee can perform different activities, and state classification and separation rules can differ. Discuss the permitted treatment with the insurer or rating authority. Preserve time records, project dates, payroll reports and documentation of changed duties so the audit reflects actual operations.

For subcontractors and staffing firms, confirm who employs the workers and who provides the required arrangement. A “1099” label or contractual statement is not a universal employee-status determination. Review current evidence, state scope and contract responsibilities; do not assume a certificate eliminates every exposure.

At renewal, reconcile work locations with the new information page. Revisit expiring state approvals, changed entities, payroll estimates and jobs expected during the coming term. Pay-as-you-go billing, if offered, does not itself correct an omitted state, classification or named insured.

Plan injury reporting and medical access before employees travel

A crew should know whom to call if someone is hurt away from the home office. Provide the appropriate insurer or state administrator’s reporting information, supervisor contacts and instructions for obtaining care under the applicable arrangement. Emergency care should not be delayed while the business debates state listings.

When an incident is reported, record the actual location, date, activity, assignment and employment facts. Preserve relevant project and travel records and follow the administrator’s reporting requirements promptly. Do not wait for a customer, subcontractor or payroll vendor to decide which system should handle the claim. The Hartford’s guidance discusses documenting and reporting remote injuries; Washington L&I separately addresses notifying Washington workers about their rights when injured outside the state. [8] [3]

Use the appropriate confidential channels for medical and personal information. A basic agency inquiry or text message should not contain an employee’s detailed medical records. If more than one jurisdiction may be involved, identify existing reports and claim contacts rather than making inconsistent statements or assuming the worker can collect duplicate benefits.

For recovery, discuss available modified duties with the claims administrator and follow applicable medical restrictions and employment requirements. A home-based assignment should not automatically be considered suitable light duty without reviewing the actual tasks. Planning these contacts before departure makes the insurance arrangement usable when employees need help.

Three situations to discuss before the first workday

A remote employee moves from Oregon to Washington

In this hypothetical example, the person keeps the same job but begins regularly working from a Washington home. The employer should review Washington employment status and L&I obligations before approving the move. Keeping Oregon payroll software or an Oregon mailing address is not sufficient evidence that the arrangement remains appropriate.

An established Oregon crew takes a finite Washington project

The traveling workers may qualify for temporary reciprocity only if the actual agreement and coverage conditions are met. A Washington local hire on the same project can need different treatment. Confirm worker-specific facts, the administrator-issued certificate and L&I acceptance instead of assuming one site means one exemption.

A service company’s occasional Idaho visits become recurring operations

Review the new work pattern, local hires, facilities and the validity of any certificate before continuing. The change can affect regulatory treatment as well as policy state listings. These examples identify questions to resolve; they do not predict whether a particular injury claim will be accepted.

A practical checklist before remote hiring or out-of-state work

Start early enough to obtain insurer decisions and required state acceptance before the assignment. Give one person responsibility for updating the roster and bringing changed facts back for review. Your first inquiry does not need Social Security numbers, medical details or payroll-account credentials.

Employer and employees: legal entities, employment relationships, regular work states, home-work arrangements and hiring facts.
Assignments: actual sites, duties, dates, recurring visits, local hires, subcontractors and any permanent facilities.
Insurance: current information page, Item 3.A and 3.C listings, forms, endorsements, employers-liability limits and named insureds.
State evidence: account arrangements, extraterritorial requests, approval letters, expiration dates and reporting obligations.
Administration: payroll estimates and allocation records, injury-reporting contacts, medical-access instructions and renewal responsibilities.

Ask what needs to change, which decisions require the carrier or state administrator, and when accepted insurance becomes effective. Obtain written confirmation of coverage and effective dates. An application, inquiry or quote alone does not bind insurance, and it does not constitute a state’s approval of a temporary-work arrangement.

Multi-state workers’ compensation questions

Does one workers’ compensation policy automatically cover employees in every state?

No. Review the actual primary state listing, Other States Insurance listing, endorsements, insurer authority and destination-state requirements. A carrier may be able to write several eligible states on one policy, but that is not an automatic nationwide guarantee. Washington statutory industrial insurance and other monopolistic-state arrangements need separate consideration.

Which state matters when an employee works remotely?

The state where the employee regularly performs work is important, but residence alone is not the only test. Hiring, employment localization, employer operations and applicable law can also matter. Tell the insurer about the actual home-work location and any regular work in other states. A permanent remote arrangement should not simply be treated as an occasional business trip.

Is there a universal 30-day exemption for out-of-state jobs?

No. Temporary-work rules, reciprocity conditions and reporting thresholds differ. The Washington–Oregon reciprocal agreement uses several factual factors rather than a universal 30-day rule. Washington’s separate supplemental reporting process and a policy’s notice conditions answer different questions. Confirm the applicable rule before work begins and again if the assignment changes.

What is the difference between Item 3.A and Item 3.C?

In the cited standard policy, Item 3.A identifies states whose workers’ compensation laws apply to primary coverage. Item 3.C is the listing for conditional Other States Insurance. Known or expected operations should be addressed in the primary listing. Other States Insurance can respond to certain newly begun operations after inception, but its conditions, notification requirements and endorsements still apply.

Can an Oregon company use its private policy for a permanent Washington remote employee?

Do not assume so. L&I identifies living and teleworking in Washington as a typical Washington-employee situation, and the Washington–Oregon agreement does not simply exempt Washington workers of Oregon employers working in Washington. Confirm Washington reporting and L&I industrial insurance or certified self-insurance requirements. Qualifying temporary reciprocity is a separate arrangement, not a private Washington statutory policy.

Does a certificate of insurance prove that a traveling crew meets another state’s requirements?

Not by itself. An ordinary insurance certificate is different from an administrator-issued extraterritorial certificate and any required state approval. Compare the evidence with the actual policy, workers, work location and dates. Idaho, for example, requires its approval before qualifying temporary out-of-state employees start work there.

Does workers’ compensation cover every injury at home or during a work trip?

No automatic outcome should be promised. Work-relatedness, the activity, travel arrangements, employment facts and applicable law matter. A remote-work agreement or company travel rule can help document facts but does not decide legal compensability. Arrange appropriate medical assistance and promptly report the incident to the proper insurer or state administrator rather than making an unsupported coverage decision yourself.

What should we send Insure Pacific before hiring or taking a job in another state?

Start with the employer entities, employee work states, duties, payroll estimates, job locations and expected dates, plus the current information page and endorsements. Identify local hires, remote moves, recurring visits, subcontractors and any state acceptance documents. Use an agreed secure channel for detailed records. Request written confirmation of accepted coverage and effective dates; an inquiry or quote alone does not bind insurance.
