ACORD 130 is the standard workers compensation application, the form that collects an employer's class codes, payroll estimates by state and classification, officer coverage elections, and experience modification factor so carriers can quote a workers comp policy. Workers compensation is the most formula-driven line in commercial insurance, and this form supplies every input in the formula. Rate times payroll per class, adjusted by the experience mod, is essentially the whole premium calculation, and all three variables come off this application.
That mechanical quality makes accuracy unusually consequential here, because every figure on the form is verified later, either by the premium audit or by the rating bureau. This page covers the classification and payroll sections, the officer inclusion and exclusion elections, and the experience mod field.
What does ACORD 130 collect?
The application collects the employer's identity and locations, then gets to the rating information that distinguishes it from every other ACORD section. The state rating worksheet lists each state where employees work and, within each state, every applicable classification with its class code, the number of employees, the estimated annual payroll, the rate, and the resulting estimated premium.
Below the rating detail come the coverage requests, employers liability limits and any endorsements needed, such as a waiver of subrogation a contract requires. The individuals section records owners, partners, and officers with their titles, ownership percentages, duties, payroll, and their inclusion or exclusion elections.
A prior carrier and loss history section covers past policies and claims, and a block of underwriting questions probes the exposures comp underwriters price carefully, including work above ground level, hazardous materials, employees traveling out of state, subcontractors used, and whether the employer provides group health benefits. The experience mod field carries the employer's current factor and its anniversary date.
How do class codes and payroll estimates set the premium?
Workers comp premium is rate times payroll, per $100 of remuneration, calculated separately for each classification and then adjusted. A clerical class might rate at a fraction of a dollar per $100 of payroll while a roofing class rates at double digits, so which code the payroll lands in matters as much as how much payroll there is.
Classification follows the governing rules of the rating bureau, NCCI in most states, and the general principle is that the business's overall operation is classified, not each task, with standard exceptions for clerical and outside sales employees who split out into their own codes when payroll records support the division.
The payroll figures on the application are estimates, and the policy is auditable, so after the term ends the carrier's premium audit examines the actual payroll records and produces a return premium or an additional bill. The operational discipline that separates clean accounts from problem accounts is payroll segregation, keeping records that break payroll out by classification and by state, because auditors assign undocumented payroll to the highest-rated applicable code. Estimate from real payroll data. The audit will find the truth regardless.
How do officer inclusion and exclusion elections work?
Most states let certain owners, partners, LLC members, and corporate officers elect whether to be covered by the workers comp policy, and the application records the election for each named individual. The default and the available choices vary by state and by entity type, which is why the form asks for title, ownership percentage, and duties alongside the election.
The tradeoff is real in both directions. Excluding an owner saves premium, since included officer payroll is charged, subject to state minimum and maximum payroll amounts used for rating, but an excluded owner injured on the job has no comp benefits and health insurance policies commonly exclude work-related injuries, which can leave a working owner personally uninsured for the exact injuries most likely to occur.
Brokers flag this hard for owners who work in the field. An excluded roofing company president who climbs ladders has made a serious bet. The election also interacts with contract work, because general contractors often require subcontractors' owners to carry coverage on themselves, precisely so an injured sole proprietor does not become the GC's comp claim:
| Application section | What it feeds |
|---|---|
| State rating worksheet with class codes and payroll | Deposit premium calculation, later verified by audit |
| Officer and owner elections | Who is covered and whose payroll is charged, per state rules |
| Experience modification field | The multiplier applied to the entire manual premium |
| Prior carrier and loss history | Underwriter verification against loss runs and bureau data |
What does the experience mod field do?
The application asks for the employer's current experience modification rate and its effective date, and this single number scales the whole premium. The mod compares the employer's actual losses to what the rating bureau expects for employers of the same size and classifications, with a factor above 1.00 raising premium and a factor below 1.00 lowering it.
Underwriters do not take the declared figure on faith, since mods are promulgated by the rating bureau and verifiable, but the field matters for quoting accuracy and for spotting problems early. A mod that is missing when the employer's size should qualify it for experience rating, or a declared figure that does not match the bureau's worksheet, sends the submission back for clarification.
The mod also explains why comp claims echo for years. Losses typically feed the mod calculation for three policy periods, so a bad year keeps charging premium long after the injured employee has recovered.
Where can you see the actual form?
Menlo does not reproduce ACORD forms because they are copyrighted by ACORD Corporation. Licensed agencies and carriers access current editions through acord.org and complete the 130 inside their agency management systems, usually alongside the ACORD 125 master application. Employers see the completed form when their broker sends the package for review and signature, and reviewing the class codes, payroll figures, and officer elections before signing is the practical protection.
Frequently asked questions
What is the difference between ACORD 125 and ACORD 130?
ACORD 125 is the master commercial application covering the applicant's identity, operations, and general history. ACORD 130 is the workers compensation application carrying the comp-specific rating data, class codes, payroll by state, officer elections, and the experience mod. Package submissions include both, though workers comp is sometimes submitted with the 130 alone.
Can owners exclude themselves from workers comp?
In many states yes, depending on entity type, title, and ownership percentage, and the election is recorded on the application. The premium saving is real, but an excluded owner injured at work generally has no comp benefits and may find health insurance excludes occupational injuries. Ask your broker how your state and entity type handle it.
What if I do not know my experience mod?
If your business is large enough to be experience rated, your current carrier or the rating bureau can provide the mod worksheet, and your broker can pull it. New or small businesses below the premium eligibility threshold simply are not experience rated yet, and the field reflects that.
Why does the application ask about subcontractors on a workers comp form?
Because uninsured subcontractors can become the hiring employer's employees for comp purposes. Auditors ask for certificates of insurance on every subcontractor, and payments to subs without their own comp coverage get charged as payroll on the hiring employer's policy.
