Kentucky Workers Compensation

Coverage attaches at the first employee, family and part-time workers count, and the fine for going without runs per employee per day

A Louisville shop owner asked me last spring how many people he had to hire before workers compensation became his problem. He had two part-timers and a nephew who came in on Saturdays, and he was sure that was under whatever the line was.

There is no line in Kentucky. Coverage attaches at the first employee, and the part-timers and the nephew were all three of them employees. He had been uninsured for eleven months, which in Kentucky is not one violation but a fine that multiplies by headcount and by day.

This page is Kentucky only. How the system works in general, what exclusive remedy buys you and what a policy actually pays for, our guide to workers compensation insurance already covers, and none of that gets repeated here.

The wider state picture lives elsewhere too. Hiring paperwork, breaks, final pay and the Kentucky Civil Rights Act sit in the Kentucky HR compliance guide, and the hourly rate sits on the Kentucky minimum wage page.

TL;DR
Kentucky requires workers compensation insurance from the first employee, and family, temporary and part-time workers all count. Policies come from any authorized carrier, from KEMI, or from approved self-insurance. Employers report injuries to the carrier within three working days and the carrier files with the state within one week. Going uninsured costs $100 to $1,000 per employee per day.

Last checked: August 18, 2026Workers compensation rules change. The General Assembly amends KRS Chapter 342 in most sessions, the Department of Workers’ Claims updates its forms and its posting notice without announcing it, and your own carrier and policy number change the moment you switch insurers. Re-check this page against the Department’s site before you renew, and re-check it the first time you put anyone on payroll.

When Kentucky Coverage Becomes Mandatory

Kentucky employers must carry workers compensation insurance once they have one employee. KRS 342.630 makes any person other than one engaged solely in agriculture a mandatory employer the moment it has a single employee subject to the chapter, and the same rule covers every public body in the state.

The Department of Workers’ Claims leaves no room to argue the count. Its employer FAQ states that family members, temporary workers and part-time workers are considered employees, and its compliance branch repeats that there are no exceptions for any of the three.

Securing that liability has exactly two forms. The employer buys a policy from a carrier authorized to write workers compensation in Kentucky, or it is authorized by the Commissioner to pay benefits directly and posts security for them. Both routes are set out in KRS 342.340.

Your businessHeadcountCoverage required
Retail store with one part-time clerk1Yes. The first employee triggers it
Restaurant with three staff and a family member on weekends4Yes. Family and part-time workers count
Contractor with two seasonal helpers2Yes. Temporary workers count
Corporation with two officers and no other staff2Yes, unless each officer files a notarized Form 4 rejection
LLC of two qualified members with no employees0No, until a nonqualified member or an employee is added
Sole proprietor with no employees0No, and the owner is covered only by election
Farm employing four field workers4No. An employer engaged solely in agriculture is outside KRS 342.630
Ohio business sending a crew into Kentucky for a weekAnyYes. A separate Kentucky policy is required

The out-of-state trap catches more employers than the headcount one. Every Kentucky policy must pay the employer’s entire Kentucky liability, so an all states endorsement on a home state policy does not qualify, and the Department specifically rejects the C-110 filings Ohio employers rely on at home.

Agriculture is the one genuine carve-out, and it is narrower than it sounds. An employer engaged solely in agriculture is outside KRS 342.630 and agricultural employment is exempt under KRS 342.650, but a business that farms and also runs a retail operation is not engaged solely in agriculture. The Department’s employer responsibilities page states the general rule for everyone else.

Who Is Excluded From Kentucky Coverage

Kentucky exempts twelve specific classes of employee and treats business owners separately from staff. The exemptions are listed in KRS 342.650, they are narrow, and a worker who does not appear on that list is presumed to be inside the system.

Owners are governed by KRS 342.012 instead. Sole proprietors, qualified partners and qualified members of an LLC are employees only if they elect to come in and buy the endorsement that covers them. A partner or member is qualified only where the partnership agreement or articles show on their face that the person shares in profit or loss and participates in decisions.

CategoryHow Kentucky treats it
Sole proprietorNot an employee. Covered only by electing in under KRS 342.012 and adding the endorsement
Qualified partner or LLC memberOutside the count while the agreement shows shared profit or loss and a role in decisions. The Department may ask to see the document
Nonqualified partner or LLC memberCoverage required. A person paid regular amounts for work, with no share of profit or loss and no say in decisions, is a worker
Corporate officerAn employee under KRS 342.640(2), so counted and covered unless the officer files a notarized Form 4 rejection with the Department
Family, part-time and temporary employeesCounted and covered. The Department states there are no exceptions for any of the three
Domestic servantsExempt where the household has fewer than two employees each regularly working 40 or more hours a week in domestic service
Short-term home maintenance and repairExempt for up to 20 consecutive work days in or about the employer’s private home, or the business premises where the employer has no other covered employees
Agricultural laborExempt. An employer engaged solely in agriculture is also outside the mandatory coverage rule
Aid or sustenance workersExempt where the only return for the service is aid or sustenance from a religious or charitable organization
Workers covered by federal lawExempt where a rule of liability is provided by federal law, except federal black lung benefits
Ministers and church cemetery caretakersExempt with no set agreement for fixed regular payment, or where the work is no more than 10 hours a week
Carpool and vanpool participantsExempt while riding or driving to and from work in a voluntary program
Direct sellersExempt as defined in Section 3508(b)(2) of the Internal Revenue Code
Independent contractorsNot a statutory exemption. The label has to survive the Department’s tests, and KRS 342.610(2) can make you liable for an uninsured subcontractor’s employees

The full statutory list, including the religious sect and Medicaid waiver provider categories that rarely reach a small business, sits in KRS 342.650 as published by the Legislative Research Commission.

Independent contractor status is where audits actually turn. The Department weighs whether the work is a regular and recurring part of your business, how much control you keep over the details, whether the worker has a specialized trade and a separate place of business, and what the written contract says. Our guide to worker misclassification covers the same tests in more depth.

Subcontracting does not move the risk either. Under KRS 342.610(2) a contractor who subcontracts work that is a regular or recurrent part of its own business is liable for compensation to the subcontractor’s employees unless that subcontractor secured coverage. Collect the certificate before the crew starts, and check it against the Department’s coverage lookup rather than taking a photocopy on faith.

Never ask an employee to sign a rejection
Kentucky lets an individual reject the Act with a notarized Form 4 filed with the Department, and corporate officers use it legitimately. KRS 342.395(2) makes it illegal to require that form as a condition of getting or keeping a job, or to fire someone for refusing to sign it. The penalty runs $200 to $2,000, and each form executed by an employee or applicant is a separate offense. The Commissioner also refuses to give effect to any rejection that was not voluntary, so the paperwork buys nothing and the exposure is real.

Where a Kentucky Employer Buys the Policy

Kentucky is not a monopolistic state. Coverage comes from one of three places: a private carrier authorized by the Department of Insurance to write workers compensation in Kentucky, the Kentucky Employers’ Mutual Insurance Authority, or self-insurance authorized by the Commissioner of the Department of Workers’ Claims.

Most small employers take the first route through an agent who represents several approved carriers. That is the answer the compliance branch gives when employers ask how to obtain a policy, and shopping the account across agents is how you find out whether your classification codes are being applied consistently.

KEMI is the piece that confuses people. KRS 342.803 created it as a self-supporting public body operating what the General Assembly itself called a competitive state fund, and it writes both in the voluntary market and as the insurer of last resort. So an employer nobody else will quote still has somewhere to go, without the state having a monopoly on anything.

RouteWho it fitsWhat it takes
Private carrierMost small employersAn agent representing approved carriers, accurate payroll and class codes, an annual audit
KEMI, the state fundEmployers in the voluntary market and those who cannot place coverage elsewhereA quote like any other carrier. KEMI also acts as the insurer of last resort under KRS 342.803
Individual self-insuranceLarge employers able to carry the riskAssets exceeding liabilities by at least $10 million, Form SI-02 with three years of audited financials filed two months ahead, five years of loss data, security of at least $500,000, and excess insurance of at least $10 million per occurrence
Group self-insuranceGroups pooling risk, typically by industryApproval and oversight, with groups now regulated by the Kentucky Department of Insurance

The self-insurance requirements above come from the Department’s security and compliance page, which also explains that a certified self-insurer stays certified until the Commissioner revokes or modifies the certificate. For a business with fifteen people this route is theoretical, and the $10 million net asset test is why.

Two administrative details matter once the policy exists. Your carrier files evidence of coverage with the Department within ten days of issuing the policy, and both you and the carrier must report a cancellation immediately. Building permits are the other checkpoint: a local building official cannot issue one without proof of coverage, and an applicant with no employees certifies exemption on a prescribed affidavit.

A drug-free workplace program cuts the premium by 5 percent
Kentucky certifies drug-free workplace programs under 803 KAR 25:280, and a certified employer may receive a 5 percent discount on its workers compensation premium. Certification is voluntary, there are no application fees, and the program requires a written policy distributed to and acknowledged by employees, an employee assistance program, training, testing through an approved laboratory and confidentiality rules. Source: Kentucky Department of Workers’ Claims, drug-free workplace program page.

Posters and What Goes in the New Hire Packet

Kentucky requires one workers compensation posting, and your carrier supplies it. KRS 342.610 requires every covered employer to post the notice at its principal office and at any other location where employees customarily report for payroll and personnel matters.

The content is prescribed rather than decorative. The notice names your workers compensation carrier and policy number, sets out how an employee accesses medical care for an injury, states the employee’s obligation to give notice of an accident, and carries whatever else the Commissioner requires by regulation.

That carrier name and policy number are why the poster goes stale. Change insurers, or renew into a new policy number, and the notice on the wall is wrong until you replace it. The Department tells employers to ask their agent or carrier for a current notice if one did not come with the latest policy, and the statute puts the duty to supply copies on the carrier.

Nothing in the workers compensation chapter has to be handed to an individual new hire. The obligation is a posted notice, not a pamphlet. The statutory text sits in KRS 342.610, and the same section is what makes proof of coverage a precondition for a local building permit.

Put the claim path in onboarding anyway
The law asks for a poster. Somebody who has just crushed a finger does not read the break room wall. Give every new hire one page naming the carrier, the claim phone number, the supervisor who takes the report, and the fact that they choose the treating physician unless you run an approved managed care plan. It costs nothing, and it is the difference between a three day report and a three week one.

Kentucky Injury Reporting Deadlines

Two clocks run and neither one is generous: three working days to your carrier, one week from there to the state. KRS 342.038(3) requires the employer to report any work-related injury or disease, including an alleged one, to its carrier within three working days of being notified.

The employee clock runs first. KRS 342.185 requires notice of the accident to be given to the employer as soon as practicable after it happens, and the Department tells workers to report to a supervisor as soon as possible, including for conditions that build up from repeated motion.

FilingWho files itDeadline
Notice of accidentEmployee to the employerAs soon as practicable after the accident (KRS 342.185)
Report of the incidentEmployer to its carrier or payment obligorWithin 3 working days of receiving notification, witnessed or not (KRS 342.038(3))
First report of injuryCarrier or payment obligor to the Department of Workers’ ClaimsWithin one week of receiving the employer’s notification, for an injury causing absence from work (KRS 342.038(1))
Start of income benefitsEmployer or carrierNo later than the 15th day after the employer has knowledge of the disability (KRS 342.040(1))
Supplementary reportEmployer to the CommissionerWhen the disability ends, and again at 60 days if it lasts that long (KRS 342.038(5))
Payment of a medical statementCarrier or payment obligor to the providerWithin 30 days of receiving the statement for services (KRS 342.020(4))
Application for adjustment of claimEmployee to the DepartmentWithin 2 years of the accident, or 2 years after income benefits stop, whichever is later (KRS 342.185(1))
Cumulative trauma claimEmployee to the DepartmentWithin 2 years of a physician telling the employee it is work-related, and never later than 5 years after the last exposure

The one week filing is the carrier’s job in practice, and your job is to confirm it happened. A report required by KRS 342.038 that lands more than fifteen days after it was due draws a fine of $100 to $1,000 for each offense, and the statutory text is in KRS 342.038.

Read the trigger conservatively. The statute requires the report where the injury causes absence from work for more than one day, while the Department describes it on its own pages as an absence of one day or more. Report anything with lost time and the difference stops mattering.

Reporting is not the same as accepting the claim. The Department is explicit that filing a first report of injury does not mean the carrier has accepted compensability, so report first and let the adjuster investigate. Deciding for yourself that a claim looks weak, and skipping the report, is how a three day deadline turns into a penalty.

Penalties for Going Without Coverage in Kentucky

The Kentucky penalty is not a flat fine, which is what makes it dangerous. KRS 342.990(7)(c) sets a civil penalty of $100 to $1,000 for each offense, and for an employer who fails to maintain coverage each employee and each day of violation is a separate offense.

Run that arithmetic on a six person crew and a year without a policy and the exposure is not a parking ticket. The Department states the rule in the same terms on its employer FAQ: uninsured employers are fined $100 to $1,000 for each of the employer’s employees every day the employer is without coverage.

ViolationWhere it comes fromPenalty
Failing to maintain coverageKRS 342.990(7)(c), civil$100 to $1,000 per offense, with each employee and each day counted separately
Failing to comply with the coverage requirementKRS 342.990(9)(a), criminal$100 to $1,000, or 30 to 180 days imprisonment, or both, for each offense
Knowingly authorizing the violationKRS 342.990(9)(c)Personal and individual liability, jointly and severally, for an owner, partner, LLC principal or corporate officer, surviving dissolution of the entity
Injured worker paid by the Uninsured Employers’ FundKRS 342.760(4)The employer repays the fund everything it paid, and the cabinet is subrogated to the worker’s rights
Employee sues insteadKRS 342.690(2)Exclusive remedy is lost. The worker may claim benefits and sue for damages, and you cannot plead fellow servant, assumption of risk or contributory negligence
Deducting premium from wagesKRS 342.420 and 342.990(7)(c)$100 to $1,000 per violation
Filing a required injury report more than 15 days lateKRS 342.990(7)(a)$100 to $1,000 for each offense
Accident caused by an intentional safety violationKRS 342.165(1)Compensation increased 30 percent where the employer intentionally failed to comply with a safety statute or regulation, and decreased 15 percent where the employee did

Kentucky does not run the administrative stop-work order that some states use. The tools in Chapter 342 are the citation, the daily civil penalty, criminal referral and personal liability, though the Commonwealth’s own published guidebook to workers compensation warns that a business operating with no coverage may be closed by court action.

Enforcement is not passive. The compliance branch runs a field enforcement section that investigates coverage through on-site visits to Kentucky employers, works Uninsured Employers’ Fund claims and follows up complaints, and the Commissioner issues the citation and states the penalty directly.

Once cited, you have fifteen working days to tell the Commissioner you intend to contest, or the citation becomes final. A contest goes to an administrative law judge under KRS Chapter 13B, with a ruling due within sixty days and an appeal to Franklin Circuit Court. The full penalty section is KRS 342.990.

Criminal enforcement follows a defined path rather than sitting on a shelf. The Commissioner files a complaint with the local prosecutor, and if that prosecutor does not act within twenty days the matter is certified to the Attorney General, who is directed to initiate proceedings.

The civil liability is worse than the fine anyway. An uninsured Kentucky employer loses the protection of exclusive remedy, so the injured worker can take compensation and also sue for damages, and three of the oldest defenses in employment law are unavailable in that suit.

What a Kentucky Employer Does When Someone Is Hurt

Do these in order, and do the first three the same day. Kentucky puts the choice of physician with the employee in most cases, so the value you add in the first hour is speed and a clean record, not steering.

1
Get medical care and know who picks the doctor
Under KRS 342.020(4) the injured employee selects medical providers unless you have designated a managed health care system approved by the Department of Workers’ Claims. Even then, an employee who received emergency care may elect to continue with that provider. Care runs under a single treating physician or group, and the employee may change that designated physician once before having to show reasonable cause.
2
Take the report and write it down
KRS 342.038(1) requires every covered employer to keep a record of all injuries received by employees in the course of employment. Capture the date and hour, what happened, the nature of the injury and the witnesses while the memory is fresh. Date-stamp it and keep it somewhere you can find it two years later, because that is how long the employee has to file.
3
Report to your carrier within three working days
This is your deadline, not the carrier’s. It runs from the moment you receive notification of the incident or alleged incident, and the Department is explicit that it applies whether or not you or a coworker witnessed the injury. The carrier investigates compensability. Your job is to hand it over inside three working days and to keep proof that you did.
4
Confirm the first report of injury reached the Department
The carrier or other party responsible for paying benefits files the first report with the Department of Workers’ Claims within one week of your notification, for any injury causing the employee to miss work. Ask for confirmation rather than assuming. A required report filed more than fifteen days late carries a fine of $100 to $1,000 per offense.
5
Watch the benefit clock
No income benefits are payable for the first seven days of disability unless the disability continues more than two weeks, in which case benefits run from day one. Benefits are paid on your regular payday starting with the first payday after seven days, and in no event may they begin later than the fifteenth day after you have knowledge of the disability. Late installments carry interest.
6
File the supplementary report and keep paying the medical side
KRS 342.038(5) requires a supplementary report when the disability ends, and again at sixty days if it runs that long. Medical statements are paid directly to the provider within thirty days of receipt. Never deduct any part of the premium from the employee’s wages: KRS 342.420 prohibits it and the fine runs to $1,000 per violation.
7
Keep the OSHA log separate and do not retaliate
A workers compensation claim and an OSHA recordable injury are decided under different criteria, and Kentucky runs its own state OSHA plan covering private employers. Make the two determinations separately every time. Retaliating against someone for filing a claim is its own exposure and it is the fastest way to turn a routine medical-only file into litigation.

The recordkeeping mistake usually runs the other way, with every comp claim copied onto the log automatically. Our guide to OSHA forms 300 and 301 covers which injuries are actually recordable.

One habit is worth building before the renewal arrives. Premium is rated on payroll by classification code and trued up at audit, so job assignments and payroll records that stay accurate as people move around are what keep the audit bill from becoming a surprise. Our guide to the workers compensation audit covers what the auditor asks for.

If the piece that keeps slipping is the employee record itself, who works where, under what job title, hired on what date, with which documents signed, that is the record FirstHR was built to hold. FirstHR is an onboarding and HR platform, not an insurer or a broker, and it does not sell coverage. It keeps the file straight so the numbers you hand your carrier are the right ones.

Key Takeaways
Kentucky requires workers compensation from the first employee under KRS 342.630, with no small business threshold and only an employer engaged solely in agriculture outside the rule.
Family, temporary and part-time workers count, and corporate officers are employees under KRS 342.640(2) unless they file a notarized Form 4 rejection with the Department.
Sole proprietors, qualified partners and qualified LLC members sit outside the count under KRS 342.012 and are covered only if they elect in through an endorsement.
Buy from any authorized carrier, from KEMI as the competitive state fund and insurer of last resort, or self-insure with more than $10 million in net assets and Commissioner approval.
Post the notice naming your carrier and policy number, report injuries to the carrier within three working days, and confirm the carrier files with the state within one week.
Going uninsured costs $100 to $1,000 per employee per day, carries criminal exposure and personal liability for owners and officers, and loses you exclusive remedy protection.

Frequently Asked Questions

How many employees before workers compensation is required in Kentucky?

One. KRS 342.630 makes any person other than one engaged solely in agriculture a mandatory employer once it has a single employee subject to the chapter. The employer secures that liability by buying a policy from a carrier authorized to write workers compensation in Kentucky, or by being authorized by the Commissioner to pay benefits directly. Out-of-state employers performing any work in the state need a policy providing Kentucky coverage.

Do part-time, temporary and family employees count in Kentucky?

Yes, all three. The Department of Workers’ Claims states that family members, temporary workers and part-time workers are considered employees, and its compliance branch confirms there are no exceptions for any of them. Officers of a corporation count as well under KRS 342.640(2). The people outside the count are sole proprietors, qualified partners and qualified LLC members, and only until they elect coverage for themselves.

Does Kentucky have a state workers compensation fund?

Yes, and it is competitive rather than monopolistic. KRS 342.803 created the Kentucky Employers’ Mutual Insurance Authority as a self-supporting public body that writes coverage in the voluntary market and as the insurer of last resort. Employers may also buy from any carrier authorized by the Department of Insurance to write workers compensation in Kentucky, typically through an agent, or apply to self-insure.

What poster does Kentucky require, and does anything go to a new hire?

KRS 342.610 requires a workers compensation notice posted at the principal office and anywhere else employees report for payroll and personnel matters. It names your carrier and policy number, explains how to access medical care and states the employee’s duty to report accidents. Your carrier supplies it. Nothing in the workers compensation chapter requires a separate pamphlet for each new hire.

How fast must a Kentucky employer report a work injury?

Within three working days to your carrier, counted from the moment you are notified of the incident or alleged incident, whether or not anyone witnessed it. The carrier or other payment obligor then files the first report of injury with the Department of Workers’ Claims within one week for any injury causing lost time. A required report filed more than fifteen days late draws a fine of $100 to $1,000 per offense.

What happens if a Kentucky employer has no coverage?

The civil penalty is $100 to $1,000 for each offense, and each employee and each day of violation counts separately. The same failure carries criminal exposure of $100 to $1,000 or thirty to one hundred eighty days in jail, or both. Owners, partners, LLC principals and corporate officers who knowingly authorized the violation are personally liable, and the employer must reimburse the Uninsured Employers’ Fund for anything it pays.

Who chooses the doctor for a Kentucky work injury?

The employee, unless you have designated a managed health care system approved by the Department of Workers’ Claims. An employee who received emergency care may elect to keep treating with that provider even under a plan. Treatment runs through a single treating physician or group, and the employee may change that physician once before needing to show reasonable cause. Your carrier pays providers directly within thirty days.
