The Basics
What Cost Segregation Does for Kentucky Property Owners
A cost segregation study identifies building components, HVAC systems, specialty flooring, parking surfaces, interior finishes, exterior lighting, that qualify for accelerated depreciation on 5-, 7-, or 15-year schedules rather than the default 27.5-year (residential rental) or 39-year (commercial) building schedule. Front-loading those deductions increases first-year cash flow and lowers current-year federal taxable income.
In Kentucky, the federal benefit works the same way it does anywhere, the One Big Beautiful Bill (OBBBA, P.L. 119-21) permanently restored 100% bonus depreciation for qualified property placed in service after January 19, 2025, and that federal benefit applies to Kentucky properties in full. State-level treatment is where Kentucky is different: Kentucky has never adopted federal §168(k) bonus depreciation. For property placed in service after September 10, 2001, Kentucky follows the depreciation deduction allowed under IRC §168 as in effect on December 31, 2001, meaning no bonus depreciation on the Kentucky return. Federal bonus depreciation must be added back, and property depreciates via pre-bonus MACRS on the Kentucky return.
Federal Deduction Is Where the Money Is
Kentucky’s Tax Landscape: Why Cost Segregation Matters Here
Individual Income Tax
3.5% flat for 2026 (down from 4% in 2025 via revenue-triggered reduction schedule enacted in 2022 by the Kentucky General Assembly).
Corporate Income Tax
5% flat on C-corporations. Kentucky also imposes an LLET (Limited Liability Entity Tax), a gross receipts-based alternative minimum tax on C-corporations and limited liability pass-through businesses that applies even when the business doesn’t turn a profit.
Local Occupational Taxes
Kentucky is one of few states that levies additional income-based taxes at the county and municipal levels (occupational license taxes and net profit taxes). These vary by locality and are separate from state income tax.
Bonus Depreciation Conformity
Decoupled. Kentucky follows IRC §168 as in effect December 31, 2001, which does not include §168(k) bonus depreciation. Federal bonus depreciation is added back on the Kentucky return; property depreciates via pre-bonus MACRS.
§179 Expensing
Kentucky caps §179 at $100,000, well below the federal $2.56M cap for 2026. Federal §179 amounts above the Kentucky cap require an addback and subsequent-year recovery on the Kentucky return.
Property Tax
~0.83% effective on owner-occupied housing (Tax Foundation 2026), moderate. A separate lever from income tax; cost segregation operates on income tax through accelerated depreciation.
§481(a) Catch-Up
For Kentucky properties owned more than a year without a study, an automatic accounting-method change (Form 3115 under Rev. Proc. 2015-13 and its updates) captures all missed depreciation into the current tax year at the federal level, no amended returns required.

Real Numbers
What First-Year Savings Might Look Like in Kentucky
Results depend on property type, cost basis, construction year, and applicable depreciation rates, and we run a free benefit analysis before you commit to a study so you can see projected numbers first.
As a reference point, an Ambrose Group engagement on a $2.9M commercial property delivered $657,692 in first-year depreciation increase and $230,192 in first-year tax savings. In Kentucky specifically, the federal Year 1 savings apply fully; the Kentucky state benefit is spread across the useful life of the reclassified components under pre-bonus MACRS (no state-level bonus stacking). Given Kentucky’s 3.5% individual and 5% corporate rates, the federal deduction is where the bulk of the study’s economics live.

Frequently Asked Questions
Does Kentucky conform to federal bonus depreciation rules?
No. Kentucky has never adopted federal §168(k) bonus depreciation. For property placed in service after September 10, 2001, Kentucky follows IRC §168 as in effect on December 31, 2001, a version that does not include bonus depreciation. Federal bonus depreciation is added back on the Kentucky return; property depreciates via pre-bonus MACRS. Your federal Year 1 tax savings from a cost segregation study are fully preserved.
What is Kentucky’s §179 cap?
Kentucky caps §179 at $100,000, well below the federal $2.56M cap for 2026. Federal §179 amounts above $100,000 require an addback and subsequent-year recovery on the Kentucky return. This is one of the lowest §179 caps in the country.
How does Kentucky’s flat income tax interact with a cost segregation study?
Kentucky has a flat 3.5% individual income tax for 2026 (down from 4% in 2025) and a 5% flat corporate income tax. Kentucky also imposes an LLET (Limited Liability Entity Tax), a gross receipts-based alternative minimum tax on C-corporations and LLCs. Local occupational taxes at the county and city level are additional. Because Kentucky decouples from bonus depreciation and caps §179 low, the federal Year 1 benefit is where most of the study’s economics live.
What Kentucky commercial property types benefit most from cost segregation?
Louisville logistics and distribution (UPS Worldport, Amazon, DHL), Toyota Georgetown manufacturing and auto parts operations, bourbon distilleries and aging rickhouses along the Kentucky Bourbon Trail, healthcare across Louisville and Lexington, and multifamily in both metros. Specialty industrial and equipment-heavy property produces the strongest results.
Can I do a cost segregation study on a Kentucky property I’ve owned for years?
Yes. A §481(a) adjustment via an automatic accounting-method change (Form 3115 under Rev. Proc. 2015-13 and its updates) lets you capture all missed depreciation from prior years into the current tax year without amending past returns. Especially valuable for long-held Kentucky manufacturing, distillery, and industrial properties.
How do you do a cost segregation study on a Kentucky property when you’re based in Texas?
Cost segregation is governed by federal tax law, so the methodology is identical regardless of state. Our engineer works either through an in-person Kentucky site visit or, for well-documented properties, a virtual site inspection using high-definition video, construction documents, and interactive tools. Both are IRS-compliant.
What construction era of Kentucky property produces the strongest cost segregation outcomes?
Properties placed in service since 1987 are eligible under current IRS guidance, and studies limited to the last 7–10 years tend to deliver the strongest ROI. Kentucky’s Toyota Georgetown expansions, Louisville logistics buildout, and bourbon industry investment cycle have produced substantial newer commercial property in the ideal window.
Does Kentucky’s LLET affect the cost seg decision?
The LLET is a gross receipts-based tax, so it isn’t directly reduced by depreciation deductions the way the corporate income tax is. Cost segregation reduces Kentucky corporate income tax and individual income tax through accelerated depreciation, the LLET operates on a different base. Your CPA should model both when planning.
What documentation do you need for a Kentucky cost segregation study?
Purchase or construction cost documentation, a current depreciation schedule from your CPA, construction plans or specs (when available), any prior appraisals, and, for renovation studies, improvement records. Because Kentucky maintains a separate depreciation schedule (no §168(k) bonus, $100K §179 cap), your CPA will need the detailed asset schedule to compute Kentucky-specific depreciation. We provide it as part of the standard deliverable.
Can you handle Kentucky multi-property portfolios? How long does a study take?
Yes, we regularly run cost segregation studies across multi-state and Kentucky-only portfolios. Common for Louisville logistics operators with multiple warehouses, distillery operators with multiple production and aging facilities, and multifamily portfolio owners. Typical study timeline is 4–8 weeks per property; complex manufacturing or distillery facilities take longer proportional to the equipment-cataloging effort.
