Workers Compensation Requirements by State Explained
Why there is no national answer on workers comp, the three facts true everywhere, six questions that decide your obligation, and how to verify your state.
Search this question and you will find a dozen fifty-state comparison tables, most of them copying figures from each other, few of them citing a state agency. They disagree with one another in places, and several of them are wrong for at least one state on any given day. This guide explains why, and shows how to get a correct answer for your own state.
The reason is structural rather than lazy. There is no general federal workers' compensation requirement for private employers and no federal agency overseeing the state programs. The federal Office of Workers' Compensation Programs runs four separate schemes of its own and says plainly that it plays no part in running or overseeing the state programs. That leaves fifty states plus the District of Columbia legislating independently, on their own schedules, with nobody reconciling the result.
Instead of another table, this guide gives you the three facts that hold everywhere, the six questions that actually determine your obligation, the ways states differ that catch small businesses out, and a method for getting that answer in one conversation. That is more useful than a table that was accurate the month it was written.
I build the people and records tooling for businesses without an HR department at FirstHR. This is general information and not legal or insurance advice; workers' compensation is state-regulated and the details change, so confirm anything here with your state agency or a licensed agent before acting on it.
What Workers Compensation Actually Is
Workers' compensation is a state-mandated insurance system that pays medical costs and partial wage replacement to employees injured or made ill by their work, without requiring the employee to prove the employer was at fault. In exchange, the employee generally gives up the right to sue the employer over the injury. That trade is the entire design.
The no-fault part is the piece employers most often misread. It means an injured employee does not have to show the business did anything wrong, which sounds alarming until you notice the other half: the business does not have to defend whether it did.
Think of a slip in a kitchen, a lifting injury in a warehouse, or a repetitive strain injury at a desk. In each case the question is whether the injury arose out of the work, not whose fault it was.
Understanding the trade explains the rest of the subject. Coverage costs money, and it also works as a liability shield, which is why the penalty for not carrying it so often includes losing that shield. An uninsured employer does not simply owe a fine. It faces the injury claim in the form the system was designed to prevent.
Most private policies come in two parts. The first pays the statutory benefits the state requires. The second, usually called employer liability, responds to injury lawsuits that fall outside the exclusive remedy. That second part is worth knowing about because in the four exclusive-state-fund states it is typically not included in what the state sells you.
Minimum Workers Compensation Limits by State
The statutory half of the policy carries no dollar limit at all. It pays whatever the state benefit schedule says the injury is worth, so there is no coverage amount for you to choose there. The minimums people ask about sit on the employer liability half instead, and there is no single national figure to quote: the number that binds you comes from your state and from the contracts you sign.
Carriers write that second part to standard limits, expressed as an amount per accident, an amount per employee for disease, and a policy aggregate for disease. A state can require more than the carrier default.
Private contracts frequently require more than the state does: general contractors, landlords, and larger customers often set a limit in the contract before they will let your people on site. Ask your agent for both numbers and buy to the higher one.
In North Dakota, Ohio, Washington, and Wyoming the question changes shape rather than disappearing. The state fund sells the statutory coverage without the employer liability part, so the limit conversation happens on a separate policy, often called stop-gap coverage, arranged alongside the state fund account.
Why There Is No National Answer
The single most useful fact in this subject is that no general national requirement exists for private employers. Workers' compensation is a state matter, and the federal role is limited to distinct programs covering particular groups of workers, such as the federal longshore law, which requires covered maritime employers to insure or self-insure their compensation liability.
The federal Office of Workers' Compensation Programs administers four disability compensation programs: for federal employees, for longshore and harbor workers, for coal miners, and for certain energy workers (Department of Labor).
The office's own guidance directs anyone who worked for a private company or a state government to their state program, and states directly that the federal office has no role in the administration or oversight of the state programs (OWCP).
The confusion is compounded by the fact that federal law does touch adjacent things. Federal workplace safety rules govern hazards and injury recordkeeping, federal wage law governs what you pay, and federal programs cover specific categories of worker.
None of those is workers' compensation for a typical private employer, and conflating them is how businesses conclude they have handled something they have not. If the question is who pays when one of your employees is hurt at work, the answer comes from your state.
This also explains a pattern that confuses new employers: two businesses of identical size, in identical industries, one state line apart, can have completely different obligations. That is the system working as designed. Each state made its own decisions about thresholds, exemptions, funding models, and enforcement, and none of them was constrained by what the neighboring state chose.
The Three Things That Are True Everywhere
Three structural facts hold across the country and change rarely. Knowing them is most of what you need before you pick up the phone.
The Texas position is the one most often misreported, so it is worth stating precisely. In Texas, private employers can choose to carry coverage but it is not required in most cases, while all Texas governmental entities must have it. Employers that choose not to provide coverage must notify their employees and the state division of workers' compensation (Texas Department of Insurance).
A Texas employer that declines coverage becomes a non-subscriber. An injured employee can then bring an ordinary claim, and the employer loses the legal defenses that the workers' compensation bargain normally provides. Whether that is a sensible trade is a real business decision rather than a formality, and one to take with an attorney rather than from an article.
Texas is not alone in stopping short of a universal mandate. The South Dakota Department of Labor and Regulation states that no law there requires any employer to carry workers' compensation insurance. It still strongly recommends coverage and notes that an uninsured employer may be sued in civil court by an injured worker.
Wyoming draws the line by type of work. According to a Wyoming Legislative Service Office memo (June 2023), the state mandates coverage only for extra-hazardous employment, and an employer outside that definition can go without, buy optional coverage from the state fund, or buy it from a national carrier.
Six Questions That Decide Your Obligation
Rather than looking up a row in a table, work through six questions. The answers to these determine everything, and having them written down turns a confusing research project into a single conversation with a state agency or a licensed agent.
The second question deserves the closest look, because the headcount number is the part everyone remembers and the counting method is the part nobody checks. A business that believes it is under a five-employee threshold because it has four full-time staff may be over it once two part-timers and a family member are counted, and it will not find out until something happens.
The fourth and fifth questions interact. An owner who has elected out of coverage and also treats several workers as contractors has built a structure where, if the classification fails, there are covered employees, an uninsured employer, and no owner coverage either. That combination is common and it is the worst version of this problem.
The classification test that matters here is the state's, not the federal one, and the two are not the same. A worker who is defensibly a contractor for federal tax purposes can still be an employee for workers' compensation in a given state, because the states wrote their own tests with their own purposes.
If a meaningful share of the people doing your work are on contractor arrangements, check them against the state test specifically rather than against the one your accountant applied.
How States Count Employees
The threshold number is only half the rule. The other half is who counts toward it, and that is where small businesses most often land on the wrong side of a line they thought they were comfortably inside.
Some states do not use a headcount at all. According to the Kansas Department of Labor, coverage there is required once gross annual payroll passes $20,000, so a small crew of well-paid people triggers it before a larger crew of part-timers would. The District of Columbia has no employee-count threshold of any kind in its statute, so the duty attaches from the first employee who performs work there.
Three of the traps in that list deserve a closer look, starting with owners and officers. A corporate officer's exclusion is usually an election rather than an automatic exemption: it typically requires a filed form and, as in Florida, can require renewal. Assuming you are excluded because you own the company, with nothing filed, means being uninsured while believing you made a choice.
The seasonal case produces an unpleasant pattern. A business that stays under a threshold for most of the year and goes over it for a busy quarter has an obligation during that quarter, and discovering it afterwards is discovering it too late. If your headcount moves seasonally, ask what your peak is and what happens at it, not what your average is.
The subcontractor point is the one that catches businesses that have no employees at all. In many states, if you hire a subcontractor who does not carry their own coverage, that subcontractor's workers can become your responsibility. Collecting a current certificate of insurance before work starts, and noting the expiration date, is the standard and cheap protection.
Nick Anisimov, FirstHR founderGetting the Answer for Your Own State
There is an official route to a correct answer, and it takes about twenty minutes. The federal Department of Labor maintains a directory of state workers' compensation officials linking every state and territory to its own workers' compensation agency (State Workers' Compensation Officials). That directory is the right starting point because it routes you to the body that actually sets the rule, not to a publisher summarizing it.
| Ask this | Why it matters | Who can answer it |
|---|---|---|
| At what number of employees does coverage become required? | The threshold varies by state | State workers' compensation agency |
| Who counts toward that number? | Part-time, seasonal, family, and owners are treated differently | State agency, in writing if possible |
| Does my industry change the answer? | Construction and agriculture frequently do | State agency |
| Can owners or officers be excluded, and how? | Usually an election with a form, not automatic | State agency or licensed agent |
| Do I buy from a private carrier or the state? | Four states sell it exclusively themselves | State agency |
| What does the state charge for being uninsured? | Penalty structures differ sharply | State agency |
| What employer liability limits apply here? | Minimum limits are set state by state, and contracts often demand more | State agency or licensed agent |
| Does my policy cover the states my people work in? | Policies are written state by state | Your agent or carrier |
Ask for the answers in writing where you can. A note in an email from the state agency, or a written confirmation from a licensed agent, is worth considerably more than a recollection of a phone call if the question ever becomes contested. It also gives you something to file rather than something to remember.
A licensed agent or broker is the other route, and often the faster one, with a caveat. An agent knows the market and the practical mechanics, and an agent is also selling a policy. Both are true. Use the state agency for what the law requires and the agent for how to comply with it efficiently, and be a little careful when what the agent says the law requires matches exactly what the agent sells.

The first sheet is one row per state where anybody actually performs work, with columns for the threshold, the counting method, whether an owner election was filed, and crucially who confirmed it and when. The second is the policy register, including a column for whether employer liability is included, which is the question that matters in the exclusive-fund states. The third tracks subcontractor certificates with expiry dates, because an expired certificate is functionally the same as no certificate.

Ryan HowardSalesUp to DateWhat Non-Compliance Actually Costs
Penalty amounts are set state by state and change, so repeating figures from a comparison table would be exactly the mistake this guide is arguing against. What is stable is the shape of the consequences, and the shapes recur across states.
The per-day structure is the one that catches people, because the intuition is that a penalty is a number and the reality is that it is a number multiplied by how long you were exposed. A business that discovers it should have carried coverage for the past eight months is not looking at a single fine. It is looking at a fine multiplied by roughly two hundred forty.
There is a quieter version of non-compliance that does not involve going uninsured at all: under-reporting payroll. Because premium is calculated from payroll and classification, an estimate that understates either produces a policy that costs less and an audit that costs more.
Most policies are audited after the period, and the correction arrives as a bill. Reporting honestly at the start simply chooses when you pay, and it keeps the relationship with the carrier intact, which matters at renewal.
The loss of the exclusive remedy is the one that matters most and gets discussed least. The system caps what an injured employee can recover because the employer bought into it. Inside the system, a serious injury produces a defined sequence of medical payments and wage replacement, calculated to a formula and handled by an insurer.
Outside the exclusive remedy, there is no schedule of benefits and no administrative process. The same injury produces a lawsuit against the business with no ceiling, defended and paid by the business, and in several states with the usual defenses unavailable. That is the difference between a cost and an existential threat to a small company.
Employers often assume the premium is the reason to hesitate, so the cost side deserves a look. Workers' compensation premiums are generally calculated from your payroll, the classification codes that describe the work your people do, and your claims history. The number is driven by what your business actually does rather than by a flat rate.
For low-hazard office work the premium is frequently far smaller than owners expect, and for genuinely hazardous work it is large for a reason. Either way, getting a quote is cheaper than estimating.
Workplace injuries are not a remote possibility even in businesses that feel low risk. According to the Bureau of Labor Statistics, private industry employers reported 2.5 million nonfatal workplace injuries and illnesses in 2024, a rate of 2.3 cases per 100 full-time equivalent workers.
The federal injury and illness statistics program publishes the industry data if you want a grounded sense of your own exposure (Bureau of Labor Statistics). The point of looking is to see that the premium is being weighed against something real, not to alarm yourself.
You Just Hired Your First Employee
The most common version of this problem is not an employer ignoring a rule. It is an employer who hired somebody, dealt with the obvious paperwork, and never learned that workers' compensation was a separate item with its own trigger.
The seventh step is worth taking seriously because workers' compensation is rarely the only thing triggered by a first hire in a new state.
Registering for state unemployment tax and getting the rest of the new hire paperwork right belong to the same conversation, and they surface the same question about where the person actually works.
Remote Workers and Multiple States
Remote work broke the assumption underneath most workers' compensation advice, which is that a business operates where it is registered. Coverage generally follows where the work is performed, and policies are written state by state.
| Situation | The question it raises | What to do |
|---|---|---|
| You hire someone in a new state | Does your policy extend there at all | Tell your agent before the start date, not after |
| An existing employee relocates | Coverage may no longer match where they work | Treat a relocation as a notifiable event |
| Someone works from home in your state | Injuries at home can still be work-related | Confirm how your carrier treats it |
| Employees travel across state lines | Which state's system applies to an injury on the road | Ask about extraterritorial provisions specifically |
| You operate in an exclusive-fund state and others | You will need a state fund account plus a private policy | Confirm employer liability is covered in both |
| A subcontractor works in a different state | Their certificate may not cover the state of the work | Check the states listed on the certificate, not just its existence |
Extraterritorial provisions are the rules that decide whether coverage follows an employee into another state, which most employers assume happens automatically. Many state systems and many policies contain terms addressing employees who temporarily work in another state, and the terms have limits: a defined number of days, a requirement that the work be temporary, or reciprocity that exists between some states and not others.
Temporary travel is usually manageable. A person who has effectively relocated is not temporary, whatever the paperwork says. The relocation row is the one that quietly creates the most exposure, because nothing happens at the moment it goes wrong.
Someone moves, tells you as a courtesy, and nobody connects it to insurance. Asking employees to report a relocation, and treating each report as a trigger for a coverage check, costs nothing and closes the gap.
The classification question sits underneath all of this and deserves its own attention, because it is the failure mode that turns a compliance question into a serious one. If a worker you treat as a contractor is found to be an employee, they count toward every threshold and are covered retroactively, so the business learns it was uninsured only after an injury. The tests differ by state and by purpose, and misclassification is worth understanding properly rather than assuming a contract settles it.
None of this is complicated once the structure is clear. It is simply local, and the mistake almost everyone makes is looking for a national answer to a question that does not have one. Your next step is small: list every state where someone works, ask each state agency the questions above, and file what you are told and the certificates you collect alongside the rest of your employee records. That turns a one-off research project into a position you can stand behind.
Frequently Asked Questions
Which states require workers compensation insurance?
All but three states require employers to provide it, subject to limited exemptions such as small employers and agricultural or domestic workers. The three are Texas, where private employers can decide for themselves whether to carry coverage; South Dakota, where state law leaves the choice to every employer; and Wyoming, where only work its statute classes as extra-hazardous must be covered. What varies enormously among the rest is the trigger: some states require coverage from the first employee, others set a threshold of three, four, or five, and construction and agriculture often follow separate rules inside a single state. Because each state legislates independently and there is no federal agency coordinating them, the only reliable answer for your business comes from your own state's workers' compensation agency.
Is there a federal workers compensation requirement?
Not for most private employers. The federal Office of Workers' Compensation Programs does run workers' compensation, but only through four separate programs aimed at specific groups: federal employees, longshore and harbor workers, coal miners, and certain energy workers. Maritime employers and coal mine operators inside those programs are legally required to secure payment of benefits. The office itself says it has no hand in operating or supervising state systems. Anyone employed by a private business or by a state government is pointed to the state program instead, so your obligations come from state law, which explains why the rules change so much from one state line to the next.
How many employees before workers comp is required?
It depends on the state and on how that state counts. Many states require coverage from the first employee. Others set thresholds commonly in the range of three to five. Two things trip people up more than the number itself. First, part-time, seasonal, and family workers frequently count even when owners assume they do not. Second, within the same state construction work often triggers coverage earlier, sometimes from the first employee, while farm work is frequently exempt or held to a higher threshold. Confirm both the number and the counting method with your state agency.
What are the monopolistic states for workers comp?
The monopolistic states are North Dakota, Ohio, Washington, and Wyoming, each of which runs an exclusive state fund. An employer there cannot shop the private market for the mandatory coverage and instead sets up an account with the state. The catch for a small business is that a state fund policy typically leaves out employer liability, the part of a private policy that responds to injury lawsuits falling outside the exclusive remedy. Many employers in these states therefore arrange separate employer liability, often called stop-gap coverage, next to the state account. Because each fund writes its own rules, check the current arrangement with the state agency.
Does Texas require workers compensation insurance?
Not for most private employers. Texas leaves the choice to private employers. An employer that buys coverage is called a subscriber. One that goes without is a non-subscriber and has to give notice to both its employees and the Texas division of workers' compensation. Government employers have no such choice: public schools, utilities, cities, counties, and every other Texas governmental entity must be covered. Going without is lawful, but it carries a cost, because a non-subscriber loses important legal protections and can be sued in an ordinary injury lawsuit by an employee who gets hurt.
Do sole proprietors and LLC members need workers comp?
Usually they may be excluded, but the mechanics matter more than the general answer. A sole proprietor or partner is generally not covered unless they elect coverage for themselves, whereas a corporate officer, and in some states an LLC member, is typically treated as an employee until an exclusion is filed; details vary with the state and the type of entity. Choosing to exclude yourself also means you have no coverage if you are hurt, so treat it as a genuine decision rather than paperwork. If you have any employees at all, the exclusion of an owner does not remove the obligation to cover them.
What happens if you do not carry required workers comp?
Consequences fall into recurring categories rather than a single fine. Many states calculate penalties per day of non-compliance, often with a stated minimum, so a short gap becomes a large number. Several can issue a stop-work order. Losing coverage typically also removes the exclusive remedy protection that normally prevents an injured employee from suing directly. Some states reach past the company to hold owners and officers personally liable, and knowing and willful failure can carry criminal exposure. On top of all of it, the injury costs land on the business.
Do you need workers comp for remote employees in another state?
Usually the obligation follows where the work is physically performed rather than where your company is registered, so a single remote hire across a state line can bring a new set of rules into play. Policies are issued state by state, so having someone on your payroll does not automatically extend your existing coverage to a new state. When you hire across a state line or an existing employee moves, ask your agent or carrier directly whether the current policy follows them instead of assuming it does.
Does workers comp cover independent contractors?
Generally not, and that is exactly why classification is the riskiest part of this subject. A label that says contractor settles nothing if the worker fails your state's test. In that case the person is treated as an employee for workers' compensation, counts toward any coverage threshold, and is covered retroactively. The exposure runs through subcontractors too: many states hold the hiring business responsible for the employees of a subcontractor who has no coverage. Review how each worker is classified, and ask every subcontractor for a current certificate of insurance before the work starts.
