Workers' Comp Insurance Forms: Who Files What, and When
Workers' comp insurance forms fall into two families: coverage forms that set up and service a policy, and claim forms that report and process a workplace injury. Almost all of them are set by your state, not the federal government, which is why there's no single national form you can download once and reuse everywhere. In practice, the injured worker starts a claim by giving notice, the employer files the First Report of Injury with its insurer, and the state workers' comp board governs which forms apply and where they go. This guide sorts the forms by family, shows who is responsible for each, lays out the filing deadlines by role, and points you to where each form lives. It closes with a state-by-state snapshot and a plain-answer FAQ.
What Are Workers' Comp Insurance Forms?
Workers' comp insurance forms come in two families: coverage forms that create and maintain an insurance policy, and claim forms that report and process an injury. Understanding that split is the fastest way to find the right form, because the two families answer completely different questions. Coverage forms ask "how do we insure this business?" Claim forms ask "someone got hurt, now what?"
Here's the simple version:
- Coverage forms set up the policy. The main one is the ACORD 130 application, joined by owner or officer exclusion forms, exemptions, and certificates of insurance.
- Claim forms handle an injury. The centerpiece is the First Report of Injury, along with the state claim or notice form the worker uses.
The reason people get stuck is the belief that "workers' comp forms" means one national packet. It doesn't. Each state runs its own system with its own form numbers, so the honest answer to "which form?" always starts with "which state, and which family." That leads straight to the first question worth settling, whether these are even federal or state forms at all.
Federal vs. State Forms
Except for federal employees, who file OWCP forms through the ECOMP portal, workers' comp forms are set by each state, so there is no single national form. If you work for a private company in Ohio, you use Ohio's system. If you work for a private company in Georgia, you use Georgia's. The federal government only runs the forms for its own workers.
That's the whole rule, and it matters because it tells you where to look. Your state workers' comp board publishes the official forms, sets the deadlines, and receives the filings. Federal workers skip all of that and go through ECOMP instead. Once you know it's your state's system in play, the next question is which specific form, and that depends entirely on your role.
The Two Families at a Glance
Coverage forms create and maintain a policy; claim forms report and process an injury, and the employer is the one party that regularly handles both. A worker mostly touches claim forms. An insurer receives and processes both. The employer, though, buys the policy with coverage forms and reports injuries with claim forms, which is why employers feel buried in paperwork that seems unrelated.
| Family | Purpose | Trigger | Main filer | Example forms |
|---|---|---|---|---|
| Coverage | Set up and service the policy | Buying or changing coverage | Employer | ACORD 130, exclusions, COI |
| Claim | Report and process an injury | A workplace injury | Injured worker + employer | First Report of Injury, state claim form |
Most people arrive here worried about the claim side, because an injury already happened. So that's where we'll go next.
The Core Claim Forms (and Who Files Each)
The injury claim starts with a First Report of Injury, or FROI: the injured worker notifies the employer and completes the state claim or notice form, and the employer then files the FROI with its insurer. That hand-off is the part people misunderstand most. The worker doesn't file the FROI, and the employer doesn't file the worker's notice. Each party owns a different piece.
| Form | Who completes it | Who receives it | When |
|---|---|---|---|
| Notice of injury / claim form | Injured worker | Employer (and state board) | After the injury, within the state notice window |
| First Report of Injury (FROI) | Employer | Insurer, then state board | Within the state reporting window |
| Insurer's report | Insurer or self-insured employer | State board | Within the state filing window |
The claim form is what protects the worker's eligibility. The FROI is what starts the insurer's file. Both carry a clock, and the clock is where a strong claim can quietly fall apart.
Who Is Responsible for Each Form
Responsibility splits three ways: the injured worker gives notice and completes the claim form, the employer files the First Report of Injury, and the insurer or self-insured employer files with the state. Keeping those lanes straight prevents the most common failure, where everyone assumes someone else handled it.
- The injured worker reports the injury to the employer and completes the state claim or notice form.
- The employer completes and files the First Report of Injury with its insurer.
- The insurer (or a self-insured employer, which pays claims itself) files the required report with the state board.
One detail rarely spelled out: in many states, if the employer won't or can't file, the insurer becomes responsible for filing the report. From that point the claim is handled by a workers comp adjuster, the person who reviews the paperwork and decides what gets paid. That backstop matters if you're a worker whose employer has gone quiet. Either way, the whole chain runs on timing, so the two clocks come next.
Filing Deadlines by Role
Two separate clocks run after a workplace injury: the injured worker must give notice to the employer, often within about 30 days but as little as a few days in some states, and the employer must report the injury to its insurer, commonly within about 5 to 10 days. Blurring these two is the mistake that costs people benefits, because meeting one clock doesn't satisfy the other.
| Clock | Who acts | Typical window | Example states |
|---|---|---|---|
| Notice to employer | Injured worker | Often 30 days; varies widely | South Dakota a few days; Pennsylvania up to 120 days |
| Report to insurer | Employer | Often 5 to 10 days | Wisconsin 7 days; Minnesota 10 days |
| File with state | Insurer / self-insured employer | Often 14 days | Minnesota 14 days |
| Fatalities / serious injuries | Employer | Usually 24 to 48 hours | Minnesota 48 hours |
Notice how the worker's clock and the employer's clock are different lengths and point at different recipients. Report the injury while it's fresh, and both clocks take care of themselves. Miss one, and the consequences differ depending on who missed it.
What Late or Missing Filings Cost You
Missing a filing deadline can expose the employer to statutory penalties and can delay or jeopardize the injured worker's medical and wage benefits, though some states still allow a late filing when there's a good reason. The two clocks carry two different risks. When an employer files late, it can face a state penalty. When a worker gives notice late, the insurer can argue the claim is barred, which is where benefits get delayed or denied.
The important nuance is that a late filing doesn't automatically end a claim everywhere. Several states permit a late notice if the employer already knew about the injury or if there's a reasonable excuse. Still, those exceptions are narrow and fact-specific, so the safe move is always to report early and in writing. If an insurer denies a valid claim or drags out payment without a reasonable basis, that can rise to workers comp bad faith, and it may be worth having an attorney review the file before a deadline closes off your options. With the timing understood, the practical question is where these forms actually live and how you submit them.
Where to Get and File Your Forms
You get official workers' comp forms from your state workers' comp board's website or your insurer, and many states now require electronic submission through EDI or a state portal rather than paper. The days of one universal paper packet are mostly gone. What you download and how you send it back depends on your state's system.
Here's the general path:
- Identify your state board. Search your state's workers' comp board or division of workers' compensation.
- Pick the right form. Match the form to your role and situation (claim, coverage, or dispute).
- Complete the fillable PDF. Most official forms are fillable PDFs you finish on-screen.
- Submit by the required method. Many states use electronic data interchange (EDI) or a state portal such as ECOMP, CompFile, or WCAIS; some still accept paper.
One exception is worth flagging. In the four monopolistic states, Ohio, North Dakota, Washington, and Wyoming, private carriers can't sell workers' comp, so employers buy coverage and file through the state fund instead. Wherever you are, your state assigns its own form numbers, which is exactly what the next section maps out.
Coverage and Policy Forms Explained
To buy a policy, an employer completes the ACORD 130, the standard workers' comp insurance application, plus any owner or officer exclusion, exemption, or coverage-election forms that adjust who the policy covers. Competitors usually list these names and stop. What they actually do is more useful to know.
| Form | What it does | Who uses it |
|---|---|---|
| ACORD 130 | The standard application insurers underwrite from (Florida uses ACORD 130 FL) | Employer buying coverage |
| Owner / officer exclusion | Removes named owners or officers from the policy | Corporations, LLCs |
| Sole proprietor exemption | Lets an owner opt in or out of coverage | Sole proprietors |
| Certificate of insurance (COI) | Proves active coverage to a third party | Contractors, clients |
| Waiver of subrogation | Waives the insurer's right to recover from a third party | Contractual relationships |
| Loss run | Reports prior claims for underwriting | Employer shopping coverage |
| Experience modification worksheet | Shows the NCCI experience modifier that adjusts premium | Employer, agent |
The ACORD 130 is the anchor because it feeds the insurer everything needed to rate and bind a policy, from payroll to loss history. The other forms fine-tune who's covered and prove that coverage to the outside world. All of these names, coverage and claim alike, shift the moment you cross a state line.
How Forms Differ State by State
The same claim-initiation form has a different name in every state: Connecticut's Form 30C, California's DWC-1, North Carolina's Form 18, and Pennsylvania's LIBC forms all do a similar job under different numbers. This is the heart of why "one national form" is a myth. The purpose stays constant; the label changes.
| State | Claim / notice form | Coverage note | Where to file |
|---|---|---|---|
| Connecticut | Form 30C (Notice of Claim) | Private market | CT Workers' Compensation Commission |
| California | DWC-1 (Claim Form) | Competitive state fund available | CA DWC / insurer |
| North Carolina | Form 18 (Notice of Accident) | Private market | NC Industrial Commission |
| Pennsylvania | LIBC forms (claim family) | Private market | PA Bureau of Workers' Compensation |
| Ohio, North Dakota, Washington, Wyoming | State-fund forms | Monopolistic: coverage through the state fund only | State fund |
This is a sample, not all fifty states. The takeaway is the pattern: find your state board, then find its form. When a claim isn't smooth, a different set of forms comes into play.
Dispute and Ancillary Forms
If an insurer denies or contests a claim, dispute forms take over: a notice to contest states the insurer's position, and a hearing request lets the injured worker escalate to the state board. This is also where medical authorization forms show up, since the insurer needs signed permission to pull the records that support or challenge the claim.
The rough sequence looks like this: a claim is filed, the insurer either accepts it or files a notice to contest (Connecticut's Form 43 is one example), and if it's contested, the worker files a hearing request to bring the dispute before the board. Return-to-work forms and supplemental reports fill in around that path as the claim evolves. Because these steps are fact-specific and vary by state, they're a good moment to confirm details with your state board. The quick, specific questions readers still ask are answered next.
Frequently Asked Questions
Who fills out the workers' comp claim form, the employer or the employee?
The injured worker starts the claim by giving notice and completing the state claim or notice form. The employer then files a separate form, the First Report of Injury, with its insurer. They're different forms with different owners, so both parties have something to complete, and neither should assume the other handled everything.
What is a First Report of Injury (FROI)?
The First Report of Injury, or FROI, is the form that officially opens a workers' comp claim by reporting a workplace injury to the insurer and, in most states, the state board. The employer usually completes and files it. It captures the who, what, when, and where of the injury so the insurer can begin processing benefits.
How long do I have to report a work injury?
Two clocks run at once. The injured worker typically must give notice to the employer within about 30 days, though some states allow only a few days and others up to 120. The employer must report to its insurer sooner, often within about 5 to 10 days. Exact windows vary by state, so confirm yours.
Are workers' comp forms federal or state?
State, in almost every case. Each state runs its own workers' comp system with its own forms and deadlines. The main exception is federal employees, who use OWCP forms filed through the federal ECOMP portal instead of a state board. There's no single national form set for private-sector workers.
What is ACORD 130?
ACORD 130 is the standardized workers' comp insurance application that employers complete to buy coverage. Insurers use it to gather payroll, operations, ownership, and prior-claims data, then rate and bind a policy. It's accepted across most states, with Florida using a state-specific version called ACORD 130 FL.
Do I file workers' comp forms with the state or the insurance company?
Usually both, in sequence. The employer first reports the injury to its insurer using the First Report of Injury. The insurer, or a self-insured employer, then files the required report with the state workers' comp board. The exact routing and whether it's electronic depends on your state's rules.
What happens if my employer won't file the form?
In many states, if the employer won't or can't file, the insurer becomes responsible for filing the report. As the injured worker, you can still protect yourself by giving written notice of the injury and contacting your state workers' comp board directly, which can explain your options and next steps.
Where do I download workers' comp forms?
Get official forms from your state workers' comp board's website or from your insurer. Most are fillable PDFs you complete on-screen. Many states also require or offer electronic submission through a portal or EDI system rather than paper. Federal employees download and file their forms through ECOMP instead.
What form do I use in my state?
It depends on your state, since each assigns its own numbers. For example, Connecticut uses Form 30C, California uses the DWC-1, North Carolina uses Form 18, and Pennsylvania uses its LIBC forms. In the four monopolistic states, you file through the state fund. Check your state board's forms page for the exact form.
What is an owner or officer exclusion form?
An owner or officer exclusion form removes named owners, officers, or partners from a workers' comp policy, so the business isn't paying premium to cover people who choose not to be covered. Rules vary by state and business type. Sole proprietors often use a related exemption form to opt in or out of coverage.
What if a deadline is missed?
A missed deadline can mean statutory penalties for the employer or delayed and denied benefits for the worker, since timely filing is usually a condition of eligibility. That said, a late filing doesn't automatically end every claim. Some states allow late notice when the employer already knew or there's a reasonable excuse.
What forms do injured workers personally sign?
Injured workers usually complete and sign the state claim or notice form that starts the claim, plus any medical authorization form that releases records to the insurer. Depending on the state and situation, a worker may also sign forms related to returning to work or, if a claim is contested, a hearing request.
