The first three articles in this series looked at Kentucky’s data center wave from the ground — the projects, the corridor, the substations, the land. This one turns the camera around and looks at it the way a capital partner does. If you are weighing a data center development play in Kentucky, two policy structures do most of the work in the pro forma: the Kentucky data center incentives written into HB 775, and the federal Qualified Opportunity Zone program that overlays parts of central and southern Kentucky. Stack them correctly and the math on a ground-up project changes materially. Here is how the two fit together, in plain terms, from where we sit working the I-65 corridor every day.
HB 775: The Sales-Tax Incentive, Tier by Tier
The single largest state driver of Kentucky’s data center activity is House Bill 775, enacted in Kentucky’s 2025 regular session (2025 Ky. Acts ch. 98) and effective June 27, 2025. It took an incentive that had been Jefferson-County-only and rebuilt it as a tiered, statewide framework. Most coverage stops at the $450 million headline. The part that matters to an investor is the tier structure, because it decides which counties your project can actually clear.
The Stites & Harbison legal summary lays the three tiers out cleanly:
- Counties of 100,000 or more population — minimum $450 million capital investment, up to 50 years of sales and use tax exemption on qualifying equipment.
- Counties of 50,000 to 99,999 population — minimum $100 million, up to 25 years.
- Counties under 50,000 population — minimum $25 million, up to 25 years.
- A colocation-campus developer (a “project organizer” under the statute) has its own path — a $150 million minimum for up to 15 years, in any county.
The qualifying scope is the data-center equipment itself: routers, servers, monitoring systems, software, network gear, fiber-optic cabling. What the bill text does not yet clearly resolve is whether construction materials, property tax, or electricity are covered — a gap worth pinning down with counsel before you underwrite the exemption too aggressively. The statute also bars stacking it with other Chapter 154 incentives or the crypto-mining electricity exemption, and it will not cover a project that merely relocates an existing Kentucky data center.
The strategic takeaway for capital is that every Kentucky county now has a tier. That is unusual. Virginia’s program, by comparison, costs the state an estimated $1.9 billion a year in forgone revenue at full buildout and is concentrated in a handful of northern counties. Kentucky’s geographic reach is the deliberate policy choice, and it is what opens the smaller-county play the earlier programs never did. We covered the full 30-project landscape and the pushback counties in Kentucky’s data center boom.
How the Kentucky Data Center Incentives Change the Investor Math
Run the tiers against real project sizes and the framework starts working for you. A regional edge-class campus in the 80-to-100-megawatt range typically carries a capital cost between $50 and $150 million depending on cooling and phasing. Drop that project into a county under 50,000 population — LaRue, Hart, Meade, Nelson, Barren — and it clears the $25 million floor without strain, unlocking up to 25 years of sales-tax exemption on the equipment stack.
A mid-size operator in a county of 50,000 to 99,999 — Madison, for instance — reaches the $100 million tier on a serious build. The 100,000-plus counties — Jefferson and Fayette, but also Hardin (Elizabethtown), Warren (Bowling Green), and Daviess (Owensboro) — sit in the top $450 million tier, where the exemption can run up to 50 years. The point is that the incentive is not a Louisville-only benefit: it scales down to the edge-class projects that fit central Kentucky’s 40-to-200-acre parcels, where much of the near-term dealflow lives. We walked through those economics in our edge data center breakdown.
The sales-tax exemption is a capital-cost line item, not a cash-flow gimmick. On an equipment-heavy build, Kentucky sales and use tax on qualifying gear is real money removed from day-one basis — and on the largest tier, the exemption runs up to half a century. That is the kind of number that moves an IRR, not just a marketing headline.
Opportunity Zones: The Federal Layer That Stacks On Top
HB 775 works on the tax you pay to build. Qualified Opportunity Zones work on the tax you pay to invest. They are separate programs, and that separation is exactly why they stack.
The Opportunity Zone program, created by the 2017 federal tax law, lets an investor roll a realized capital gain into a Qualified Opportunity Fund to defer tax on that original gain — and, if the investment is held long enough, exclude the appreciation on the new investment from capital-gains tax entirely. It was built to steer patient capital into designated lower-income census tracts. Kentucky has 144 such tracts, and several sit directly on the corridors this series has been tracking.
The one closest to our own work is the Cave City / Horse Cave cluster in Barren and Hart counties, which is a designated Qualified Opportunity Zone. That is the same Barren County corridor already drawing exposition-center and hospitality investment. A ground-up development there — data center or otherwise — can be structured through a Qualified Opportunity Fund so that the equity gains ride the OZ appreciation exclusion, while a qualifying data-center project inside the county picks up the HB 775 sales-tax tier on the equipment. One is federal and gain-based; the other is state and equipment-based. Nothing about claiming one forecloses the other.
The catch worth naming plainly: Barren County (Cave City) has been operating under a data-center moratorium since mid-2024, so the OZ-plus-HB-775 stack there applies most cleanly to non-data-center development today, and to data-center use only if and when the local posture changes. That is the discipline this whole thesis requires — the incentive map and the zoning map are two different maps, and the parcel has to clear both.
Where the Two Maps Overlap
The interesting acreage is where a favorable HB 775 tier, an Opportunity Zone designation, and a workable zoning posture all land on the same parcel. In practice that means starting from the county’s population tier, filtering to the OZ tracts inside it, then filtering again to parcels with real power — 80 to 100 megawatts available now, ideally within a couple miles of a substation — and diverse fiber. The power and substation picture is its own subject, and it is usually the binding constraint before either tax layer comes into play.
Along the I-65 corridor, Hardin County sits in the top $450 million tier — the hyperscale scale its Glendale-grade infrastructure was built to attract, while LaRue, Hart, and Meade fill in the under-50,000 tier where a $25 million edge build clears easily. The land side — what a data-center-grade parcel is worth to a developer, and how a landowner should think about it — we broke down in a companion piece on data-center-ready land for Kentucky landowners. Read the two together and you have both sides of the same table.
How to Actually Underwrite This
If you are moving from thesis to term sheet, the sequence we would run is straightforward. First, confirm the county population tier and model the HB 775 exemption against your equipment budget, not your total project cost — the exemption is scoped to qualifying gear. Second, check whether the target tract is a designated Opportunity Zone and, if so, structure the equity through a Qualified Opportunity Fund early, because the gain-rollover clock and the fund’s timing rules are unforgiving if you set them up late. Third — and this is the one that kills more deals than either tax question — verify power availability and local zoning posture before you fall in love with a parcel. Incentives do not build substations, and a moratorium does not care about your OZ election.
Done in that order, the Kentucky stack competes with anything in the second-wave Midwestern data-center belt: a statewide sales-tax exemption that scales down to edge-class projects, a federal capital-gains shelter on designated tracts, land that still prices like Kentucky farmland, and a corridor whose power was overbuilt for a battery plant. Rare combination, and it is early.
Where to Look First
If you want to see what is actually on the market inside these tiers, start with the commercial inventory along the corridor. Hardin County’s mid-tier seat is anchored in Elizabethtown commercial listings, with the Glendale commercial corridor carrying the infrastructure spillover. The under-50,000 edge tier shows up in Radcliff commercial and in the LaRue County seat at Hodgenville commercial. For the full spine, the I-65 corridor search pulls the whole Louisville-to-Tennessee stretch.
