Two. Kentucky’s small-employer definition sets a floor of at least two employees, and it tests that floor twice — once as an average across the preceding calendar year and again on the first day of the plan year. The ceiling matters less than most expect; the floor is what decides whether a very small Kentucky business is in this market.
That is unusual enough to be worth spelling out, because the number you will find on a general federal page is not the number Kentucky’s statute carries. Below is the Kentucky text itself, what each of its two tests actually asks, where the band stops at the top, and why the definition is worth getting right before anything else happens.
Kentucky’s answer, in the statute’s own words
The definition lives in the Kentucky Insurance Code, in the definitions section that governs the whole of Subtitle 17A. KRS 304.17A-005(44) reads:
(44) ‘Small employer’ means, in connection with a group health plan with respect to a calendar year and a plan year, an employer who employed an average of at least two (2) but not more than fifty (50) employees on business days during the preceding calendar year and who employs at least two (2) employees on the first day of the plan year;
That single sentence carries both tests, and it joins them with and rather than with or. The section was last amended effective April 5, 2024, and the Legislative Research Commission serves it as live text with no repeal marker against it.
Its neighbor does a second job. KRS 304.17A-005(45) defines the term small group, and it covers two different kinds of buyer — a small employer with two to fifty employees, and an affiliated group or association with two to fifty eligible members. Those are different tests counting different things, and an association route to coverage is a subject this post does not describe: the subtitle handles employer-organized associations in separate provisions, and they were not read for this post.
The floor is two, and Kentucky tests it twice
Take the two limbs of KRS 304.17A-005(44) apart, because they can disagree with each other.
The first limb is a look-back. It asks what the employer averaged across business days during the preceding calendar year. That is a historical measurement, made over a year that has already closed, and it does not care what today looks like.
The second limb is a snapshot. It asks how many employees the employer has on the first day of the plan year — a single date, forward-looking from the first limb’s point of view, and tied to the plan rather than to the calendar.
An employer can satisfy one and fail the other. A business that averaged well above the floor last year but has shrunk to a single employee by the day its plan year opens fails the second limb. A business that only started hiring in the autumn may clear the first day comfortably and still not have the preceding-year average behind it. The statute asks for both, in one sentence, joined by and.
This is the part worth carrying into a conversation with an insurer or an agent. When somebody asks how many employees you have, the honest answer for this purpose is usually two answers, and the second one has a date attached to it.
Who falls outside the definition, and it is not an edge case
The floor of two does real work in Kentucky, and it does it at the smallest end of the market.
A sole proprietor with no employees is outside KRS 304.17A-005(44) on both limbs — no preceding-year average of at least two, and no two employees on day one. A one-employee business is in the same position for the same reason. Neither is a small employer as Kentucky’s Insurance Code uses that term, and the small-group market rules that attach to that term do not attach to them.
That is not a small population in a state with a lot of very small businesses, and it is the practical difference between Kentucky and a general description of the small-group market written for the country as a whole. It is also the single most useful thing to establish before you spend any time comparing plans, because the answer changes which market you are shopping in rather than merely which plan you pick. Our overview of how a first group plan comes together treats this as step one for exactly that reason.
Where the band ends, and Kentucky writes the other side expressly
Plenty of states leave the top of the small-group band to be inferred from the bottom of something else. Kentucky does not. KRS 304.17A-005(32)(a) defines large group to mean an employer with fifty-one or more employees.
So the line is written from both directions, in the same definitions section, in adjacent subsections. An employer under the ceiling and at or above the floor is a small employer; an employer at fifty-one or more is a large group. You do not have to reason from one to the other, and you do not have to rely on a summary of either.
The same subsection also reaches affiliated groups and certain fully insured employer-organized associations, counted in eligible members rather than in employees. That is named here and not described, for the same reason as above.
Why the number decides more than you would think
The band is not a formality. Being inside it is what makes a specific body of Kentucky law apply to your group health plan and to the insurer that writes it.
The clearest example is availability. KRS 304.17A-200(3) provides that each insurer that offers health benefit plan coverage in the small groups market shall accept every small employer that applies for coverage
. That protection is written for a small employer, which is the defined term above — so the headcount question is upstream of the acceptance question.
The conditions travel in the same breath, and they matter. The same section lets an insurer establish group participation rules requiring a minimum number of participants or beneficiaries enrolled in relation to a specified percentage or number of those eligible, and requires those rules to be applied uniformly to small employers in the small group market. It also preserves narrow denial grounds tied to a network plan’s service area and demonstrated capacity, and to an insurer’s financial reserves. None of those is a health-status test, and none of them changes the headcount definition — but “an insurer must accept you” and “an insurer may set participation rules” are two halves of one accurate sentence, and either half on its own misleads.
The point for this post is narrower and harder to get wrong: the protections attach to a defined term, and the defined term is a headcount.
Why a general federal page will give you a different floor
This is the trap in Kentucky, and it is worth naming directly because the wrong answer is served from a .gov domain.
The federal overview of the Small Business Health Options Program at healthcare.gov states a general size range for a business or non-profit purchasing that coverage. Read carefully, that page carries no date of any kind — no last-updated stamp, no plan year on the band sentence — and the word Kentucky does not appear on it anywhere. It is a national summary, and its floor is not the floor Kentucky’s statute sets.
A second federal page, the CMS table of state-specific rating variations, summarizes the federal default band in the same shape. Kentucky’s cell under the column for a state-expanded definition of small employer is blank on that table, and on the page’s own reading rule a blank cell means the federal default applies. That corroborates exactly one thing: Kentucky has not raised its ceiling above the federal default. It says nothing at all about the floor, and it does not license the federal floor for Kentucky.
Neither band is reproduced here, in digits or in words, because printing either one next to the word Kentucky is how the wrong number gets into circulation. The affirmative statement in KRS 304.17A-005(44) beats an inference from a blank cell and beats a national summary, and an employer who checks their work against a general federal page instead of against the statute will correct a right answer into a wrong one.
Read the operative text, not the heading
One more discipline, because it is the reason this post quotes rather than summarizes.
KRS 304.17A-005 is headed only Definitions for subtitle. The heading carries no number and no band. Everything above lives in the operative text of the subsections, and a reader who skims section headings looking for a headcount will not find one anywhere in Subtitle 17A.
The same caution applies to how the Legislative Research Commission serves the material. A live Kentucky statute section arrives as a PDF, and the HTTP response tells you nothing about whether what you are reading is current. The evidence of currency is printed on the document’s own face: the Effective line and the History line. For KRS 304.17A-005 those read to an amendment effective April 5, 2024, with the chain running back to the section’s creation in 1998. Check those two lines, every time, before relying on a Kentucky statute you pulled yourself.
There is one further hazard inside the same section. KRS 304.17A-005(11) defines Eligible individual, and a reader searching that section for the words eligible and individual will land on it first. It is a creditable-coverage test for an individual seeking coverage. It is not a definition of who counts as an employee, and it has nothing to do with the band.
What this post does not answer
Two boundaries, stated rather than implied.
Who counts as one employee. The band counts employees, and that is as far as this post goes on the subject. Whether a particular part-time worker, seasonal hire, owner, partner, LLC member or S corporation shareholder counts toward that average is a separate question, and nothing read for this post supports an answer in either direction. It is worth settling with your own tax adviser before you put a number on an application.
Which plans the subtitle reaches. Kentucky’s Insurance Code does not apply every one of its rules to every kind of coverage; KRS 304.17A-008 sets that boundary and lists what the subtitle leaves out. That is a different subject with a different answer, and enumerating it here would be the wrong place for it.
If your headcount sits near the floor — or wobbles across it between the look-back year and the first day of your plan year — that is exactly the situation to put in front of someone before you shop. The Kentucky background we hold in one place is on our Kentucky small business health insurance page, and if you would rather start with your own numbers, send us the headcount and the plan-year date.
The bottom line
Kentucky sets its own small-employer band, and the number that catches employers out is the floor rather than the ceiling. Under KRS 304.17A-005(44) an employer must have employed an average of at least two employees on business days during the preceding calendar year and must employ at least two on the first day of the plan year. Both limbs have to be met, and a generic federal page will tell you something different.
Frequently asked questions
How many employees does a Kentucky small employer need?
At least two, and the requirement is tested twice. KRS 304.17A-005(44) defines a small employer as one who employed an average of at least two but not more than fifty employees on business days during the preceding calendar year and who employs at least two employees on the first day of the plan year.
Can a Kentucky sole proprietor with no employees buy a small-group plan?
Not as a small employer under KRS 304.17A-005(44). A sole proprietor with no employees, and a business with one employee, sit outside that definition on both of its limbs — the preceding-year average and the first-day-of-plan-year test.
Where does Kentucky’s small-group band end?
Kentucky writes the other side of the line expressly. KRS 304.17A-005(32)(a) defines a large group to mean an employer with fifty-one or more employees, so the small-group band stops where that one starts rather than being left to inference.
Will a federal small-business page give me the right Kentucky number?
Not for the floor. General federal pages state a national summary band, and at least one of them carries no date of any kind and never mentions Kentucky. Kentucky’s operative floor comes from KRS 304.17A-005(44), and the statute beats a generic federal summary.
How can I read Kentucky’s definition for myself?
The Legislative Research Commission serves KRS 304.17A-005 in full. Read the operative text of subsection (44) rather than the section heading, which says only that the section contains definitions for the subtitle, and check the Effective and History lines printed on the document’s own face.
