15 things to verify on a subcontractor’s workers’ comp line when crews cross state lines. Named states, monopolistic-state coverage, employers’ liability, owner exclusions, and waivers.
Why this exists
A subcontractor’s certificate of insurance comes in, the workers’ compensation box on the ACORD 25 is filled, a policy number sits in the row, and the certificate gets filed as compliant. Then the sub’s crew works across three states on the same job, an apprentice gets hurt on the leg of the project in the state the policy never named, and the carrier denies the claim because that state was not listed on the policy. Now the injured worker has nowhere to turn but up, and an uncovered comp injury rolls onto the general contractor as a statutory employer in most states, where the GC can be on the hook for benefits the sub failed to insure. The workers’ comp line is the one place on a certificate where a single missing state code, a sole-proprietor exclusion nobody read, or a policy that does not recognize where the work actually happens turns into the GC’s payroll and the GC’s claim.
Workers’ comp is the coverage everyone assumes is handled and almost nobody verifies past the policy number. It is also the line that varies the most across state lines, which is exactly the problem on any job that crosses one. Comp is state-administered, the rules are set state by state, and a policy written and rated for one state does not automatically follow a crew into the next. The states the policy covers live in a specific place on the form, and the sub that works in five states on a policy that names two has a gap on three of them. The certificate looks clean. The coverage is not there.
Then there are the states where the rules are different in kind, not just in detail. In a small set of states, a private workers’ comp policy is not even valid, because coverage in those states has to come from the state’s own fund. A certificate showing a standard private comp policy in one of those states is not evidence of compliant coverage, no matter how good the limits look, because that policy cannot legally cover that state’s exposure. A reviewer who does not know which states work that way will accept a certificate that proves nothing, and the gap surfaces only when a worker gets hurt and the claim has nowhere to go.
That is what this checklist does. It is a verification list, item by item, for reading the workers’ comp line on a subcontractor’s certificate when the work touches more than one state. It walks the coverage the way it actually has to be read: the policy itself, the states named on it, the employers’ liability that rides alongside it, the exclusions for owners and officers, the special-fund states where a private policy does not count, the waiver of subrogation, the policy term, and the named insured. It does not set your limits, name your states, or write your subcontract, and it does not give legal or insurance advice. It gives you the structure to require comp coverage deliberately and verify it line by line, so the workers’ comp line stops slipping through review as a filled-in box.
Who uses this
- General contractors and construction managers who write subcontractor insurance requirements and run crews across state lines, and need the workers’ comp line read for the states the work actually touches, not just confirmed as present
- Risk managers responsible for matching comp coverage requirements to where subs perform work and to each state’s rules, including the special-fund states
- Contract administrators and compliance staff who review certificates of insurance as they arrive and have to confirm the comp policy names the right states and carries the right employers’ liability, not just a policy number
- Project executives who carry the statutory-employer exposure when a sub’s comp coverage fails to respond, and want to know the requirement was real before the sub mobilized
- Subcontractors who work across state lines and want to know exactly what a GC checks on the comp line so their certificate clears review the first time instead of bouncing
What’s included
This checklist walks the 15 things to verify on a subcontractor’s workers’ comp line, from the certificate to the policy behind it, when the work crosses state lines. Work it top to bottom for each sub as the certificate arrives. Each item is a pass, a fail, or an action to chase down with the sub or its broker. The point is to read the comp line the way it actually has to be read across states, so a sub never mobilizes on a certificate that shows a policy but does not cover the states where the crew works. Because workers’ comp is state-administered and the rules vary by state, confirm the specifics for each state on your job with your risk manager, broker, or counsel.
- Workers’ comp coverage is shown on the ACORD 25 with a policy number and limits. Confirm the workers’ compensation and employers’ liability section of the certificate is populated, not blank, and shows a policy number and effective dates. The standard ACORD 25 certificate of liability insurance has a dedicated workers’ comp section with its own row, so this coverage has a fixed place to live and there is no excuse for it being empty on a sub with employees. A blank comp section, or one with no policy number, is a fail to send back before anything else on the row matters.
- The states where the work happens are named on the policy. This is the item that gets missed on multi-state jobs. A workers’ comp policy lists the states it covers, and a policy rated for one state does not automatically follow a crew into another. Confirm every state where the sub will perform work is named on the policy, because comp is state-administered and a state that is not on the policy may be a state with no coverage. Read where the work is happening, then confirm the policy names those states.
- Special-fund (monopolistic) states are covered through the state fund, not a private policy. In a small set of states, a standard private workers’ comp policy is not valid, and coverage must come from the state’s own fund. As of this writing those states are North Dakota, Ohio, Washington, and Wyoming. If the sub works in any of them, a private comp policy on the certificate does not prove compliant coverage for that state, and you need evidence of coverage through the state fund. Treat work in these states as a special case and confirm the current list and the requirements with your broker, since these rules are set by each state.
- Employers’ liability coverage is present with limits. Workers’ comp pays statutory benefits; employers’ liability is the part that responds to lawsuits arising out of a work injury, and the two travel together but are distinct. Confirm the employers’ liability limits are shown on the certificate, commonly stated as three figures for each accident, disease per policy, and disease per employee. Set the limits your subcontract requires rather than accepting whatever the sub carries, and confirm them with your risk manager or broker. Do not treat any single set of numbers as a universal standard.
- Stop-gap employers’ liability is in place for any monopolistic state. Coverage from a monopolistic state fund commonly does not include employers’ liability, which leaves a gap that is usually filled by stop-gap employers’ liability added elsewhere, often to the general liability policy. If the sub works in a special-fund state, the state-fund coverage alone may not carry employers’ liability, so confirm stop-gap coverage is in place for that exposure. Verify how the sub’s program handles this with your broker, since it turns on the state and the policy structure.
- Owner, officer, and member exclusions are identified and understood. Workers’ comp policies can exclude sole proprietors, partners, corporate officers, or LLC members from coverage, and the ACORD 25 has a place to indicate when they are excluded. Confirm whether the people doing the work are actually covered or sit outside the policy as excluded owners. A one-person sub whose owner is excluded may be carrying a policy that covers no one who is actually on your site. Whether and how owners can be excluded varies by state, so confirm the specifics where the work happens.
- The named insured matches the subcontracting entity exactly. Confirm the named insured on the comp policy is the same legal entity you signed the subcontract with, character for character. A certificate naming a parent company, an affiliate, a DBA, or an individual owner instead of the contracting entity may not respond when that entity’s employee is injured. A name mismatch on the comp line is a real gap, not a typo to wave through, and it matters more on comp because statutory-employer rules pull the exposure upstream when the sub’s coverage fails.
- Waiver of subrogation on workers’ comp is in place where the contract requires it. A waiver of subrogation stops the sub’s comp carrier from coming after you to recover what it paid on a claim. A waiver on the comp policy is its own endorsement, separate from any waiver on general liability, and it is commonly added by a workers’ comp waiver-of-subrogation endorsement when a written contract requires it. If your subcontract requires a waiver of subrogation on comp, confirm the comp policy carries the endorsement and that the certificate reflects it, rather than relying on the general liability waiver.
- The policy term covers the full subcontract period. Check the comp policy’s effective and expiration dates against the sub’s time on the project. A policy that expires mid-project leaves the back half of the work uncovered for comp, which is exactly when crews are largest and the most trades are stacked on site. Flag any comp policy set to expire before the sub’s scope completes, and put the renewal on your tracking so the coverage does not lapse while the sub’s people are still on the job.
- Out-of-state and extraterritorial coverage fits how the crew actually moves. A sub based in one state that sends crews to work in another raises extraterritorial questions: whether the home-state policy reaches the out-of-state work, and whether the work state requires its own coverage. Policies handle this through provisions and endorsements that vary, and the answer depends on the states involved. If the sub’s people cross state lines for the work, confirm the policy is set up to cover where they actually go, and verify the specifics with your broker, since extraterritorial rules are set state by state.
- The carrier’s rating and the policy’s validity for each state are acceptable. Coverage is only as good as the carrier behind it and only as good as its standing in the state where the work happens. Confirm the comp insurer meets your minimum financial-strength rating and that the policy is valid for each state on your job, remembering that the special-fund states are a separate question entirely. A sub can show a clean comp line written by a carrier or in a form that does not actually satisfy a particular state. Apply your carrier standard to the comp line and check state validity, not just the policy number.
- The classification codes fit the work the sub is actually doing. Workers’ comp premium and coverage rest on classification codes that describe the work, and a sub rated only for office or light work can be a signal the policy does not contemplate the trade it is performing on your site. You are not the sub’s auditor, but a comp line that looks mismatched to the scope is worth a question. Where the classifications look off for the actual work, confirm with the sub or its broker that the policy contemplates the trade, since classification rules are set within each state’s system.
- Cancellation-notice expectations are set and understood. Decide what notice you expect if the sub’s comp coverage is canceled mid-project, and understand how the certificate handles it. The ACORD 25 notice-of-cancellation language defers to the policy provisions, so a line on the certificate is not a standalone promise of notice. Set your expectation in the subcontract and confirm how cancellation notice on the comp policy is actually delivered, rather than assuming the certificate guarantees it.
- The comp coverage is evidenced on the certificate, not just claimed verbally. A sub telling you it has comp coverage, or emailing a screenshot of a declarations page, is not evidence the way a current certificate is. Require the comp coverage to appear on the ACORD 25 with policy number, limits, named states, and effective dates, and require any waiver endorsement and the owner or officer exclusion status to be reflected. If it is not on the certificate and backed by the policy, treat it as not in place until it is.
- The coverage matches the sub’s actual operations and footprint. Step back and confirm the comp line fits how this sub really works on your job and where. A sub that works one state, a sub whose crews cross two state lines a day, and a sub that picks up a leg of the project in a special-fund state all carry different comp exposures, and the policy has to match the reality. If the work crosses state lines, the named states matter. If it touches a monopolistic state, the state fund matters. Read the operation and the footprint, then confirm the comp line covers it.
How to use it
Set the comp requirement in the subcontract, then verify it on the certificate as it arrives. Before the sub is signed, decide what the scope and footprint actually require: the states the work will touch, the employers’ liability limits, whether a waiver of subrogation on comp is mandatory, and whether the job reaches a special-fund state that changes how coverage has to be carried. Write those into the subcontract so the requirement is real and enforceable, not a verbal expectation. Because comp is state-administered and the rules vary by state, confirm the specifics for each state with your risk manager, broker, or counsel.
When the certificate comes in, work this list top to bottom on the comp line specifically. Confirm the policy and limits, then confirm the named states against where the work will actually happen, because that is the gap multi-state jobs are most likely to miss. Check the special-fund states, the employers’ liability and any stop-gap, the owner and officer exclusions, the waiver if your contract required it, the named insured, and the policy dates against the sub’s time on the job. Anything that fails is an action item back to the sub or its broker before mobilization, not a note to revisit later.
The XLSX version is the working tool. It carries the 15 checks as rows with a pass, fail, or action status field you run per sub as certificates arrive, plus room to list the states each policy actually names, so a state gap never gets waved through. The PDF gives you a printable checklist for a binder or a COI-review meeting. The DOCX is the editable version for firms that keep their requirements in Word. Confirm your actual limit figures, named-state requirements, and clause language with your risk manager, broker, or counsel for each scope and each state, because those specifics are set by your contract and by each state’s rules, not by this checklist.
Stop reading the workers’ comp line by hand
Named states, monopolistic-state funds, employers’ liability with stop-gap, owner exclusions, waivers of subrogation, and a policy term that has to cover every day the crew is on site. Most reviewers check the box and move on. Contracts Connected reads the comp line for the states the work actually touches, flags the special-fund gaps, and tracks the renewals so a sub never mobilizes on a certificate that does not cover where the work is happening.

Frequently asked questions about the workers' comp verification checklist
Which states require workers’ comp coverage through a state fund instead of a private policy?
A small set of states require workers’ comp coverage to come from the state’s own fund rather than a private insurer, and these are commonly called monopolistic states. As of this writing they are North Dakota, Ohio, Washington, and Wyoming. In those states a standard private comp policy is generally not valid for that state’s exposure, so a certificate showing a private policy does not prove compliant coverage there. The list and the rules are set by each state and can change, and a couple of US territories operate their own funds as well, so confirm the current list and the specific requirements with your broker before relying on it. If a sub’s work touches one of these states, treat it as a special case and ask for evidence of coverage through the state fund.
How do I verify a sub’s workers’ comp covers a multi-state job?
Read the states named on the policy against where the work will actually happen. A workers’ comp policy lists the states it covers, and because comp is state-administered, a policy rated for one state does not automatically follow a crew into the next. Confirm every state the sub will perform work in is named on the policy, and treat any state where the work happens but the policy is silent as a potential gap to resolve before mobilization. For subs that cross state lines, also check how the policy handles out-of-state and extraterritorial work, since those provisions vary. Where a state on your job is a special-fund state, the named-state check is not enough on its own, because coverage there has to come from the state fund.
What is the difference between workers’ comp and employers’ liability?
They travel together on the same policy but do different jobs. Workers’ compensation pays statutory benefits to an injured worker regardless of fault, under the rules of the state administering the claim. Employers’ liability is the part that responds to lawsuits arising out of a workplace injury, the kind that fall outside the no-fault comp system, and it is commonly stated on the certificate as three limits covering each accident, disease per policy, and disease per employee. You generally want both confirmed, with the employers’ liability limits set to what your subcontract requires. In the special-fund states, employers’ liability is commonly not included in the state-fund coverage, which is why stop-gap employers’ liability becomes its own check.
Can a subcontractor exclude owners or officers from workers’ comp?
In many states, yes, and it is a real gap to watch on small subs. Workers’ comp policies can exclude sole proprietors, partners, corporate officers, or LLC members from coverage, and the ACORD 25 has a place to indicate when those people are excluded. The risk is a one-person or owner-run sub whose only worker on your site is the excluded owner, which means the policy may cover no one actually doing the work. Whether owners can be excluded, and how, is set by each state, so confirm the specifics where the work happens. When you review a small sub, check the exclusion status rather than assuming the policy covers everyone on the crew.
Does a workers’ comp waiver of subrogation need a separate endorsement?
Generally yes, and it is separate from any waiver on the general liability policy. A waiver of subrogation on workers’ comp gives up the comp carrier’s right to recover from you what it paid on a claim, and it is commonly added by a dedicated workers’ comp waiver-of-subrogation endorsement, typically when a written contract requires it. Because it is its own endorsement on its own policy, a waiver on general liability does not carry over to comp. If your subcontract requires a waiver of subrogation on comp, confirm the comp policy actually carries the endorsement and that the certificate reflects it, and verify the exact form and any state-specific rules with the sub’s broker.
Where does workers’ comp appear on the ACORD 25?
In its own dedicated section. The standard ACORD 25 certificate of liability insurance has a workers’ compensation and employers’ liability section, separate from general liability and auto, with space for the policy number, the effective and expiration dates, the employers’ liability limits, and an indication of whether any proprietor, partner, officer, or member is excluded. Read that section for the policy and the employers’ liability limits, confirm the states the policy names match where the work happens, and check the exclusion indicator for small subs. The certificate evidences the coverage; it is not the policy itself, so confirm any waiver endorsement and the named states against the policy rather than assuming the certificate row tells the whole story.
