How to Hire Employees in Kentucky: The Complete Compliance Sequence

The first Kentucky founder I helped through a first hire had done the parts everyone remembers. He had an employer identification number (EIN), a state withholding account, a signed offer letter, and a start date on a Monday. What he did not have was an occupational license account with the county where his new technician would actually be working, or a workers compensation policy with an effective date earlier than the start date.

This guide gives you the full Kentucky sequence in the order the work actually happens, with the deadline and the exposure attached to each step, checked against the agency or the statute that enforces it.

Kentucky is not a hard state to hire in. It is a state where the biggest administrative weight sits below the state level, where insurance that some states let small employers skip is mandatory here from the very first employee, and where two of the wage rules have no federal equivalent at all. None of that is complicated. All of it is easy to miss when nobody owns the checklist.

I built FirstHR because this kind of sequence is exactly what a small business without a dedicated HR person keeps dropping. The rules are knowable. The calendar reminder is what never gets set.

The Kentucky Hiring Sequence at a Glance

Ten of the eleven items below are legal obligations with a named enforcing body and a stated consequence; the eleventh, the onboarding plan, is what protects the hire. The registrations and the workers compensation policy come first. The offer, the forms, and the posted notices cluster around the start date, and the new hire report falls inside the first three weeks of employment.

The rest of this guide walks each step in the same order, with the Kentucky specifics that differ from the generic advice on hiring your first employee.

Step 1: Get Your Federal Employer Identification Number

Start with the federal Employer Identification Number, because every Kentucky registration that follows asks for it. The EIN is how the IRS identifies your business on employment tax returns and deposits. Apply through the IRS online application and the number is issued at the end of the session.

The Kentucky unemployment insurance registration is explicit about the dependency. The state employer guide lists your federal EIN among the details the registration asks for and says that if you do not have one, you must first apply for and receive it from the IRS. Founders who try to run the state registrations in parallel with the EIN application usually end up restarting one of them.

If you formed an LLC or a corporation and already hold an EIN, reuse it. If you have been operating as a sole proprietor and filing under your Social Security number, you need one now. Payroll tax deposits cannot be made against a personal Social Security number.

Step 2: Open Your Kentucky Withholding Account

Kentucky has a state income tax, so the withholding account is the first state registration. It sits with the Department of Revenue, which issues your Kentucky withholding account number and assigns the schedule on which you remit the tax you withhold. The Department of Revenue directs employers to register for withholding tax purposes through its MyTaxes portal.

Kentucky withholding is arithmetically simple compared with most states. The department states that the Kentucky withholding tax rate is 3.5 percent for tax year 2026, applied as a flat rate against wages after a standard deduction of $3,360. The rate stepped down from 4.0 percent under the individual income tax reduction enacted in House Bill 1.

Two details save trouble later. Keep the Department of Revenue account number and your federal EIN together, because Kentucky withholding filings ask for both. And confirm your assigned filing frequency at registration rather than assuming quarterly, because the department sets it based on expected withholding volume, and a monthly filer who files quarterly accrues penalties from the first month.

Step 3: Register for Unemployment Insurance

Unemployment insurance sits with a different agency and follows a different trigger. You register with the Kentucky Office of Unemployment Insurance through the Kentucky Unemployment Insurance Portal (KUIP), reached from kcc.ky.gov. The portal replaced the older KEWES system for employers in summer 2026.

The 2026 employer guide from that office says you need an account if you employ workers in Kentucky, and the portal decides from your registration answers whether you are liable and from what date.

For a for-profit business other than agriculture, the guide gives the liability test: you become liable if you pay at least $1,500 in gross wages in a single calendar quarter, or if you have at least one worker performing service in any part of 20 different weeks out of a calendar year.

For the 20-week test, the workers do not have to be the same people each week, and the weeks do not have to be consecutive. Most small businesses making a genuine first hire clear the first test inside the first quarter.

New employers do not choose their unemployment contribution rate. Kentucky assigns new employers other than contract construction a beginning rate of 2.70 percent, while new contract construction employers get the maximum rate under the schedule in effect that year. Contributions apply only to a capped amount of wages per employee: according to the Office of Unemployment Insurance, the taxable wage base is $12,000 for 2026, up from $11,700 in 2025, with the surcharge at 0.00 percent.

Step 4: Open Local Occupational License Accounts

This is the step that has no analogue in most states, and the one Kentucky employers skip most often. Kentucky cities, counties, and school districts levy occupational license fees on wages earned inside their boundaries, and the Department of Revenue collects none of them. Each jurisdiction registers you separately, sets its own rate, picks its own forms, and runs its own filing calendar.

The scale is the part that surprises people. A presentation given to a Kentucky legislative committee in October 2025 by the Kentucky Association of Counties and the Kentucky League of Cities counted roughly 170 cities and 87 counties levying the tax on payroll. Registering with the state touches none of it.

The practical move is to build the jurisdiction list before the first payroll run rather than after the first notice. Write down every city and county where the new hire will physically perform work, including job sites and client locations, then check each one for an occupational license fee and register where it applies. Getting this wrong produces notices from local governments that coordinate neither with each other nor with the state.

The worksheet below is that list. One row per place work is performed, with the account number and the filing calendar sitting next to it.

Step 5: Put Workers Compensation in Force Before the Start Date

Kentucky requires workers compensation insurance from the first employee, and it is not elective for the employer. KRS 342.630 makes any person, other than one engaged solely in agriculture, that has one or more covered employees in Kentucky mandatorily subject to the workers compensation chapter. There is no small employer threshold to grow into.

KRS 342.650 lists the exemptions, and they are narrow. They include agricultural workers, a domestic servant in a private home where the employer has fewer than two employees each regularly working 40 or more hours a week in domestic employment, and short-term maintenance, repair, or remodeling work lasting no more than 20 consecutive work days at a private home (or at the premises of an employer with no other covered employees).

Two more exemptions cover people performing services in return for aid or sustenance from a religious or charitable organization and members of qualifying religious sects. None of these exemptions helps a business hiring its first commercial employee.

The Department of Workers Claims, inside the Education and Labor Cabinet, enforces the requirement. Under KRS 342.990, violations carry a civil penalty of not less than $100 and not more than $1,000 for each offense, and for employers who fail to maintain coverage on their employees, each employee and each day of violation counts as a separate offense.

Step 6: Write the Posting, Make the Offer, and Deliver the Notice

Kentucky has no statewide pay transparency mandate and no salary history ban reaching private employers, so the general requirements for what a job posting must contain apply without a state overlay.

Kentucky has also not enacted a ban-the-box statute covering private employers; the fair-chance measures in the state attach to public hiring and public contracting rather than to private applications.

Two Kentucky rules do reach the hiring stage. KRS 336.220 makes it unlawful for an employer to require any employee or applicant to pay the cost of a medical examination, or of furnishing any records the employer requires as a condition of employment. If your role needs a physical, a drug screen tied to that examination, or records the employer demands, the employer pays.

The second is a genuine Kentucky first-hire step. Under KRS 344.040(3), an employer must give new employees written notice at the commencement of employment of the right to be free from discrimination related to pregnancy, childbirth, and related medical conditions, including the right to reasonable accommodations, and must conspicuously post the same notice at the place of business in an area accessible to employees.

KRS 344.030 supplies the coverage line, setting the pregnancy accommodation duty at employers with 15 or more employees in the state, and lists the accommodations. They include more frequent or longer breaks, time off to recover from childbirth, modified equipment, appropriate seating, temporary transfer to a less strenuous position, job restructuring, light duty, a modified work schedule, and a private space other than a bathroom for expressing breast milk.

Background checks are otherwise governed by federal law and by the general rules in state background check law. Kentucky adds a useful protection on the other side of the process: KRS 411.225 immunizes an employer from civil liability for disclosing information about the job performance, professional conduct, or evaluation of a current or former employee to a prospective employer, when the employee or that prospective employer asked for it.

The KRS 411.225 immunity falls away only if the plaintiff proves the information was disclosed knowing it was false, with reckless disregard for its truth, or with intent to mislead, or that the disclosure was itself an unlawful discriminatory practice under KRS Chapter 344. Reference calls in Kentucky are safer to give than most employers assume.

Step 7: Complete Form I-9 by the Third Business Day

Every employer in the United States must complete Form I-9 for every new hire to verify identity and authorization to work. This is federal law and Kentucky adds nothing to it, but the deadline is tight, and a late Section 2 is an easy mistake to make.

The employee completes Section 1 no later than the first day of work. You complete Section 2 within three business days of the start date by examining original documents the employee chooses to present. You cannot tell the employee which documents to bring. U.S. Citizenship and Immigration Services (USCIS) leaves that choice to the employee, and demanding specific documents with intent to discriminate is unlawful document abuse under federal law, a problem separate from any deadline.

Kentucky places no employment verification requirement on employers beyond federal I-9 compliance and has no state E-Verify mandate. Employers may enroll in E-Verify voluntarily, and some do because a federal contract requires it or because one standard across several states is easier to run. Enrolling never replaces the I-9.

Step 8: Collect the Withholding Forms Before the First Paycheck

Every Kentucky new hire completes federal Form W-4, which sets federal withholding. Kentucky Form K-4 is the state withholding certificate; it does not carry allowances the way the old federal form did.

According to the employer instructions on the 2026 Form K-4, the Department of Revenue requires a K-4 only to document an exemption from Kentucky withholding or a request for extra withholding. When neither applies, you withhold under the state formula and need no K-4 on file.

The reciprocity exemption matters more in Kentucky than in most states because of geography. Kentucky maintains income tax reciprocity with seven states: Illinois, Indiana, Michigan, Ohio, Virginia, West Virginia, and Wisconsin. Five of those share a border with the Commonwealth, and an eligible employee who lives in any of the seven checks box 4 on the K-4 so you can stop withholding Kentucky income tax.

The K-4 attaches conditions to two of the seven: a Virginia resident must commute daily, and an Ohio resident qualifies only if not a shareholder-employee holding 20 percent or more of an S corporation. The older stand-alone Form 42A809, last revised in 2007, is still posted, but the Department of Revenue employer instructions point commuters to the K-4.

In the Cincinnati, Evansville, and Huntington commuting belts, a meaningful share of a Kentucky employer's staff lives across a state line. Getting that K-4 on file before the first payroll run avoids a refund conversation the following spring.

Collect all of it before day one rather than on day one. Everything on that list except the employer half of the I-9 can be handled in advance, which turns the first morning into an introduction to the work rather than an hour of forms. That sequencing is the entire point of structured new hire paperwork.

Step 9: File the New Hire Report Within 20 Days

Kentucky employers must report each new employee within 20 days of the hire. KRS 405.435 requires an employer to provide the information to the Office of the Attorney General when it hires an employee, and the same obligation applies when you rehire or permit the return to work of someone who was laid off, furloughed, separated, granted leave without pay, or terminated.

Filings go through the Kentucky New Hire Reporting Center, which is the intake point for the office that now runs child support enforcement in the Commonwealth. The report must carry the employee name, address, and Social Security number, plus the employer name, address, and federal and state employer identification numbers where assigned, and the date services for remuneration were first performed.

The statute lets you satisfy the report by submitting a copy of the employee W-4 form or an equivalent form provided by that office, which is why this step sits immediately after the withholding forms.

The penalty structure escalates rather than firing on day 21. If an employer fails to report, written notice of the requirement goes out. If nothing is filed within 20 days of that notice, a second notice follows.

The statute reserves its administrative fine of $250 per calendar month per person for a narrower case: the report is still missing 20 days after the second notice, or is false or incomplete, and the failure results from a conspiracy between employer and employee to keep the information from being filed. No fine is imposed for a period shorter than one full calendar month.

Step 10: Post the Notices and Onboard Through Day 90

Two things happen at the start date. The required notices go up, and the actual onboarding begins. The notices are a one-time setup task. The onboarding is where the money you just spent on hiring either returns or evaporates.

Kentucky adds a posting requirement that many employers miss because it comes from the workers compensation chapter rather than the labor chapter. KRS 342.610 requires every covered employer, at its principal office and at other locations where employees customarily report for payroll and personnel matters, to post a notice stating the name of its workers compensation insurance carrier and the policy number, the means to access medical care for injuries, and the employee obligation to give notice of accidents. Your carrier supplies the notice, so ask for it when the policy binds.

On top of that sit the state notices from the Education and Labor Cabinet, the Kentucky civil rights and pregnancy accommodation notices, and the federal set covering the FLSA, the Employee Polygraph Protection Act, and USERRA. Both the state and the US Department of Labor publish these free. There is no reason to buy them from a poster vendor.

The Cabinet publishes the state set on its required posters page, including a wage and hour poster and a workplace safety poster. The safety poster is a state one because Kentucky runs its own OSHA-approved State Plan, which covers most private workplaces in the state.

I built the AI onboarding wizard in FirstHR for exactly this stretch. The offer letter and the pregnancy accommodation notice go out with e-signature. Form I-9, W-4, and K-4 go on the first-day list as tasks for the new hire, and completed forms are kept in their employee file; the forms themselves are completed outside the platform. The 20-day new hire report gets a task with its own due date, and the wizard turns the job description into a 30-60-90 day plan instead of leaving the first quarter unplanned.

Kentucky-Specific Rules That Change How You Employ People

Six Kentucky rules reshape the employment relationship from the first hire onward. Each differs enough from the generic national picture that copying a handbook or a pay calendar from another state produces a compliance gap.

The seventh day premium deserves emphasis because no federal rule produces it. KRS 337.050 requires an employer who permits an employee to work seven days in one workweek to pay time and a half for the time worked on that seventh day. It does not turn on crossing 40 hours.

The statute's main carve-out applies where the employee is not permitted to work more than 40 hours during that workweek, and in that case the employer may credit overtime already paid for the same hours under another law or contract. The statute adds a short list of occupational exclusions, and its definition of employee leaves out any officer, superintendent, foreman, or supervisor whose duties are principally limited to directing or supervising other employees.

Pay timing is the second rule employers get wrong by assumption. KRS 337.020 requires every employer doing business in Kentucky to pay each employee, as often as semimonthly, all wages earned to a day not more than 18 days before the payment date. Under KRS 337.055, the final paycheck for an employee who leaves or is discharged is due no later than the next normal pay period after separation, or 14 days after the separation date, whichever occurs last. Kentucky applies the same clock to a resignation and a discharge.

Kentucky is an at-will state, with the narrow public policy exception the courts recognize when a discharge violates a fundamental and well-defined policy expressed in a constitutional or statutory provision. That makes handbook language worth reviewing before the first hire, because a poorly drafted employee handbook can undercut at-will employment by implying job security the business never intended to promise.

Two coverage thresholds are worth knowing early. Under KRS 344.030, the Kentucky Civil Rights Act reaches employers with eight or more employees in the state in each of 20 or more calendar weeks, except that its disability provisions and its pregnancy accommodation duty reach employers with 15 or more.

Kentucky requires no vacation, holiday, bereavement, or sick leave from private employers, paid or unpaid. It does require reasonable personal leave of up to six weeks, on written request, when an employee receives an adoptive child under the age of ten, under KRS 337.015, and that statute also requires parity: an employer that gives paid leave or other benefits to birth parents must give the same type, amount, and duration to adoptive parents.

What worked for me

The Kentucky rule that cost me time was the local one. I had the state accounts open and assumed that was registration finished, then learned that the county where our field tech actually worked levied its own occupational license fee with its own form and its own calendar. Nothing catastrophic happened, but we filed late for two quarters and the notices came from a government that had no visibility into the state accounts we had opened correctly. Now the jurisdiction list gets built from the job description before the offer goes out, and it lives with the payroll setup records.

City Requirements: Louisville, Lexington, and Northern Kentucky

Kentucky city rules are almost entirely about tax rather than about employment standards. No Kentucky city or county sets a minimum wage of its own, and the wage, hour, leave, and separation rules above apply uniformly statewide. What varies by city is the occupational license fee and who has to register for it.

Louisville shows how the layers stack. According to the Louisville Metro Revenue Commission, the 2.2 percent resident rate is not one tax but three: Louisville Metro at 1.25 percent, the Transit Authority of River City at 0.2 percent, and the School Boards Tax at 0.75 percent. Non-residents working in Jefferson County pay 1.45 percent, the same package without the school board component.

Employers file Form W-1 quarterly, and any employer that withheld more than $3,000 in any one of the preceding four quarters also owes monthly deposits due 15 days after the month ends.

Northern Kentucky is where the local and reciprocity rules collide. An employer in Boone, Kenton, or Campbell County frequently has staff living in Ohio and working across more than one Kentucky county in the same week. Those employees claim the reciprocity exemption on Form K-4 to stop Kentucky income tax withholding, but the local occupational license fee still follows the worksite, because it is a tax on work performed inside the boundary rather than a tax on the resident. The two rules point in different directions and both have to be applied.

The practical advice is short: comply with Kentucky state law everywhere in Kentucky, and treat the local layer as a per-worksite question rather than a per-company one. Confirm fair-chance and living wage terms separately if you bid on a municipal contract, because those conditions attach to the contract rather than to your general hiring practice.

Employee or Independent Contractor: Kentucky Charges Twice for a Wrong Answer

Misclassifying a Kentucky worker produces two separate liabilities that arrive from two different agencies on the same set of facts. The unemployment side comes first: if the Office of Unemployment Insurance determines that the services were covered employment, you owe back contributions, interest, and penalties for the entire period, and the reserve account that drives your future rate is rebuilt around the corrected wages.

The workers compensation side is usually larger. Someone who should have been classified as an employee also should have been covered, so the coverage penalty under KRS 342.990 runs per employee and per day for the same stretch, and the exclusive remedy under KRS 342.690 was never available for any injury in that window.

Kentucky adds a trap for anyone who subcontracts. Under KRS 342.610, a contractor who subcontracts all or part of a contract is liable for compensation to the subcontractor employees unless the subcontractor secured coverage first, and a person who contracts to have work performed that is a regular or recurrent part of their own trade or business is deemed a contractor for that purpose. KRS 342.690 confirms the point from the other direction: the exclusive remedy definition of employer includes that contractor whether or not the subcontractor actually secured coverage.

The guidance is not complicated. Run the control analysis before anyone is paid on a 1099 and write down the answer. Collect a current certificate of coverage from every subcontractor doing work that is regular or recurrent for your business. The gap between a properly classified employee and contractor is a few percent of payroll cost. The gap between a correct classification and a wrong one is years of back liability across two agencies.

The Mistakes That Cost Kentucky Small Businesses the Most

These are the failures that show up repeatedly at Kentucky small businesses making a first or second hire. Most of them are sequencing errors rather than knowledge gaps. The founder knew the rule and ran the steps in the wrong order.

The common thread is that compliance fails on the calendar, not in the reasoning. Nobody sets out to run an uninsured week or to file a new hire report on day 31. The task simply arrives during a stretch when the founder is doing four other jobs. That is why reminders and task workflows do more good at this scale than another compliance summary would.
