Workers compensation requirements: the four kinds explained
Workers compensation requirements come in four kinds: securing cover, telling workers, reporting injuries, and contract demands. Each has its own authority.
Four different things get called workers compensation requirements, and they come from four different places. Mixing them up is how a business ends up confident it is compliant because it holds a policy, while quietly failing an obligation that has nothing to do with the policy at all.
They are, in order: securing the cover, telling your workers, reporting and recording injuries, and satisfying the people who hire you. Only the first is about buying anything.
What to take away
- Cover is generally mandatory for employers, and everything specific about it — who counts, when it starts, which categories are treated differently — is set by your state's workers' compensation act.
- The authority is your state's workers' compensation board or agency, whatever it is called. The Texas Department of Insurance's Division of Workers' Compensation, California's Division of Workers' Compensation, the New York State Workers' Compensation Board and the Florida Division of Workers' Compensation are the same kind of body under different names, and each publishes its own rules, forms and deadlines.
- Injury recordkeeping for workplace safety is a separate obligation, run by the federal Occupational Safety and Health Administration under the recordkeeping standard at 29 CFR 1904, with its own forms: the 300 Log, the 300A annual summary and the 301 incident report.
- Worker status is decided by your state's legal test, not by what your contracts call people.
Requirement one: securing the cover
Coverage for employees is generally mandatory for employers. Everything after that sentence is state law.
States set the rules: which workers count, when coverage starts, which categories are treated differently, and whether owners and officers are in or out. States genuinely differ.
How coverage is secured and what happens without it vary. Some states run a workers' compensation fund of their own — California's State Compensation Insurance Fund and the New York State Insurance Fund are two — and some let qualifying employers self-insure, usually after posting security with the board. Penalties for operating uncovered are statutory, and a state's act commonly pairs a fine with a stop-work order and leaves the employer directly liable for the injured worker's benefits.
The employee count at which cover becomes compulsory is a state figure, and states draw that line in different places: some reach employers with a single employee, while others carve out small employers or particular categories of worker. A count borrowed from another state is worth nothing here, so the only number that matters is the one your own board publishes, and the board is the place to get it.
Ask your state's workers' compensation board, which goes by different names in different places and publishes the actual rules, forms, and deadlines for its own state.
If you employ people in more than one state, you have more than one board to ask. Ask before anyone travels.
The question of who is your employee is often harder than whether you need cover. States apply their own tests, and a worker your paperwork describes as a contractor can be an employee for these purposes anyway. That, and the rest of the system's structure, is set out in the main guide to this line.
Requirement two: telling your workers
Most states require employers to inform employees about the system. That means a notice posted where staff can see it, in the current version your board issues, identifying your workers' compensation insurer or administrator and telling the worker where to go and how to file a claim. It also means specific information an injured worker has to be told at the point of injury, which in most states includes handing over the state's own employee claim form rather than a copy of your policy — in California, for example, that form is the DWC-1. The content and the format are prescribed, and using a generic template or another state's poster does not satisfy it.
Get the current version from your board. These get revised, and an out of date notice on the wall is a common and entirely avoidable finding.
Requirement three: reporting, and the separate business of recording
This is where two systems get confused, and the distinction is worth learning properly because they run in parallel.
Reporting to the comp system. When someone is injured, there are usually obligations to notify your insurer and to file with the state, on the state's forms and within windows set by statute. Most states call the insurer-side document the first report of injury, and your carrier usually files it, but the notice duty is yours. The windows are shorter than people expect — days from the injury rather than months — and your board publishes both the forms and the timing.
Recording for workplace safety. Separately from any of that, the federal Occupational Safety and Health Administration (OSHA) requires most employers to keep records of work-related injuries and illnesses under its recordkeeping standard at 29 CFR 1904. The paperwork is three forms: the OSHA 300 Log, the 300A annual summary that has to be posted each year, and the 301 incident report for each case. Employers with 10 or fewer employees at all times in the previous calendar year, and employers in the low-hazard industries the standard lists, are partially exempt from routine recordkeeping. Reporting is separate again: a fatality has to be reported to OSHA within 8 hours, and an inpatient hospitalization, an amputation or the loss of an eye within 24 hours. The OSHA material on injury and illness recordkeeping sets out who it applies to and what it asks for.
They are not substitutes. Filing one does not discharge the other, the triggers are different, and a workplace can be inside one system and outside the other. Find out which apply to you and treat them as two lists.
Requirement four: what customers and contracts demand
Businesses that hire you routinely require evidence of comp cover, and this is contractual rather than statutory. Expect a certificate of insurance on the standard ACORD 25 form, showing carrier, policy number, limits and effective dates. Expect too a request for a waiver of subrogation in the hiring party's favor, which on a workers' compensation policy is a specific endorsement your carrier has to issue, and sometimes an alternate employer endorsement or confirmation of which states your policy contemplates.
There is a reason they ask, and it runs the other way too. In many states, statutes push responsibility up the chain when a subcontractor has no cover of its own, so an uninsured sub can become the hiring business's problem.
If you engage subcontractors, collect their evidence before work starts and keep it current, because an uninsured sub can also be picked up as your payroll when the audit arrives. Matching a contractual demand to what a policy actually delivers works the same way as on the liability side, and is covered in the liability requirements guide.
What your insurer requires of you
- Accurate classification of each employee, and payroll records that support how it was split.
- Records kept in the shape the year-end audit will ask for, from the start of the period.
- Notification before employees begin working in a state the policy does not contemplate.
- Prompt reporting of injuries, in the manner the policy specifies.
- Cooperation with the claim, and evidence of subcontractors' own cover.
Read the audit worksheet before signing it. Classification errors are common, correctable, and permanent if nobody raises them.
Where each answer comes from
Obligation, benefits, forms, deadlines, worker status questions and penalties: your state workers' compensation board. Safety recordkeeping and reporting: OSHA, the federal Occupational Safety and Health Administration, and any state plan that operates in its place. Insurer conduct: your state insurance department. A disputed claim, a penalty notice, or a genuine argument about whether someone is an employee: an employment lawyer in your state.
Injuries to people who are not your employees are a different system entirely, described in the liability overview. Employees hurt while driving for work sit in both conversations at once, which is discussed in the commercial auto guide. What differs by sector is in the industry guide.
Common questions
How many employees before I need cover?
That is set by your state, and it is exactly the question to put to your state's board rather than to any website. Some states require cover from the first employee, while others exempt small employers or specific categories of worker, so the answer differs across state lines and the cost of using the wrong state's answer is a statutory penalty.
Are owners and officers covered automatically?
State-specific, and often handled by filing a form to elect in or out. Your board will say what applies and what has to be filed.
We only use contractors. Does any of this apply?
Possibly, because status is decided by your state's legal test rather than by your contracts, and because uninsured subcontractors can create obligations for the business that hired them. That these systems are built state by state is why an answer borrowed from another state is worth nothing here. This is worth a professional opinion rather than a guess.
Does a certificate from a subcontractor protect me?
It is evidence, not protection. Check it is current, check which states it covers, and re-collect it when it expires rather than filing it once at the start of the job.
