The Basics
What Cost Segregation Does for Tennessee Property Owners
A cost segregation study identifies building components, HVAC systems, specialty flooring, parking surfaces, interior finishes, and 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 Tennessee, 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 Tennessee properties in full. Tennessee state-level treatment is unique: Tennessee statically conforms to the TCJA depreciation rules (not OBBBA). Under TCJA’s phase-down schedule (which OBBBA superseded federally but Tennessee still follows for state excise tax), Tennessee allowed 80% bonus in 2023, 60% in 2024, 40% in 2025, and 20% in 2026, with 0% bonus depreciation allowed for Tennessee excise tax in 2027 and later unless the legislature changes state law. However, Tennessee conforms to OBBBA’s §179 expansion to $2.5M (indexed to $2.56M for 2026) with the increased $4M phase-out, creating an asymmetric planning opportunity. Businesses with significant Tennessee operations may elect §179 expensing instead of relying on bonus depreciation, capturing more state benefit.
Federal + Tennessee §179 Where Year 1 State Benefit Lives
Tennessee’s Tax Landscape: Why Cost Segregation Requires State Planning Here
Individual Income Tax
None on wages. The Hall Tax on interest and dividends was fully repealed effective January 1, 2021. Tennessee is one of nine states with no personal income tax on wage income.
Excise Tax
6.5% on net earnings, applies to corporations, partnerships, LLCs, and other business entities doing business in Tennessee. The Tennessee Works Tax Act exempts the first $50,000 of net earnings from excise tax for tax years ending on or after December 31, 2024.
Franchise Tax
Applied on the greater of net worth or a real/tangible property base. Minimum franchise tax is $100.
Bonus Depreciation Conformity
Static TCJA conformity. Tennessee follows the TCJA-era phase-down (per Tennessee Works Tax Act) 40% for 2025, 20% for 2026, 0% for 2027 and later. Tennessee does NOT follow OBBBA’s restoration to permanent 100% bonus. §168(n) qualified production property is not allowed for Tennessee excise tax purposes.
§179 Expensing: Conforms Federal
Tennessee follows OBBBA’s §179 increase to $2.5M (indexed to $2.56M for 2026) with $4M phase-out. This creates an asymmetric planning opportunity businesses can capture full §179 at both federal and Tennessee levels while bonus depreciation only partially conforms at the Tennessee level.
Single Sales Factor Apportionment
For most corporations, effective 2025.
Sales Tax
State sales tax is 7%; combined state + local sales tax averages 9.61% one of the highest in the country.
Property Tax
~0.71% effective on owner-occupied housing (moderate). A separate lever from income tax.
§481(a) Catch-Up
For Tennessee 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 Tennessee
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 Tennessee specifically, the federal Year 1 savings apply fully. Tennessee excise tax benefit for 2026 is 20% of the federal bonus depreciation deduction (Tennessee TCJA conformity); properly structured, §179 expensing at Tennessee-conforming amounts (up to $2.56M for 2026) can substantially increase the state-level Year 1 benefit. For property placed in service in 2027 and later, no Tennessee state bonus depreciation will be allowed unless the legislature changes the law.

Cost Segregation in Tennessee
Frequently Asked Questions
Does Tennessee conform to federal bonus depreciation rules?
Partially, and it’s asymmetric. Tennessee statically conforms to the TCJA depreciation rules (not OBBBA), meaning Tennessee follows TCJA’s phase-down: 40% bonus for 2025, 20% for 2026, and 0% for 2027 and later (unless the legislature changes state law). §168(n) qualified production property is not allowed for Tennessee. However, Tennessee does conform to OBBBA’s §179 increase to $2.56M for 2026. Your federal Year 1 tax savings from a cost segregation study are fully preserved; Tennessee state-level benefit is limited on the §168(k) side but preserved on the §179 side.
What is the Tennessee Works Tax Act and how does it affect cost segregation?
The Tennessee Works Tax Act (2023) coupled Tennessee with the TCJA’s bonus depreciation phase-down schedule for assets placed in service after January 1, 2023. Under TCJA (which OBBBA superseded federally but Tennessee still follows for state purposes), bonus depreciation drops to 20% in 2026 and 0% in 2027. Tennessee also exempted the first $50,000 of net earnings from excise tax and extended F&E credit carryforwards to 25 years.
How does Tennessee’s tax structure interact with a cost segregation study?
Tennessee has no individual income tax on wages (the Hall Tax on interest and dividends was fully repealed effective January 1, 2021). Business taxes: excise tax 6.5% on net earnings, plus a franchise tax on net worth. Because Tennessee has asymmetric depreciation conformity (partial §168(k), full §179), planning is critical, §179 election can capture more Tennessee state benefit for eligible property.
What Tennessee commercial property types benefit most from cost segregation?
Nashville corporate campuses (HCA, Bridgestone, Nissan HQ, Oracle, Amazon HQ2 East), Memphis FedEx logistics infrastructure, Volkswagen Chattanooga plus Ford BlueOval City EV manufacturing, HCA Healthcare and Vanderbilt medical facilities, Great Smoky Mountains corridor destination hospitality, and Nashville-metro multifamily. Automotive manufacturing, logistics, and destination hospitality typically deliver the strongest results.
Can I do a cost segregation study on a Tennessee 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 Tennessee automotive manufacturing, healthcare, Memphis logistics, and Nashville-metro corporate properties. Note: the Tennessee bonus depreciation coupling to TCJA only applies to assets placed in service after January 1, 2023, for pre-2023 assets, Tennessee historically disallowed federal bonus depreciation entirely.
How do you do a cost segregation study on a Tennessee 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 Tennessee 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 Tennessee 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. Nashville’s corporate expansion boom, Ford BlueOval City construction, Amazon HQ2 East buildout, plus Nashville-metro multifamily have produced substantial newer commercial property in the ideal window. Note that only 2023-2026 property benefits from any Tennessee state bonus depreciation (with declining percentages), property placed in service in 2027+ receives no Tennessee state bonus benefit unless the legislature changes the law.
Should Tennessee property owners consider §179 instead of bonus depreciation?
For Tennessee-heavy operations, potentially yes, for property that qualifies for both §179 and §168(k). Tennessee conforms to OBBBA’s $2.56M §179 cap but only allows 20% bonus in 2026 (0% in 2027+). §179 election can capture more Tennessee state benefit while preserving federal benefit. Your CPA should model both options for your specific facts.
What documentation do you need for a Tennessee 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 Tennessee has TCJA-static bonus + full §179 asymmetry, your CPA will need the detailed asset schedule for both federal and Tennessee optimization. We provide it as part of the standard deliverable.
Can you handle Tennessee multi-property portfolios? How long does a study take?
Yes, we regularly run cost segregation studies across multi-state and Tennessee-only portfolios. Common for Nashville corporate campus operators (HCA, Bridgestone), Memphis logistics operators with multiple facilities, automotive manufacturing operators (Nissan, Volkswagen, Ford BlueOval), and Nashville-metro multifamily portfolio owners. Typical study timeline is 4–8 weeks per property; complex automotive manufacturing, logistics, and healthcare facilities take longer proportional to the specialty-equipment cataloging effort.
