The Basics
What Cost Segregation Does for Indiana 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 Indiana, 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 Indiana properties in full. State-level treatment is where Indiana is different: Indiana has long decoupled from federal §168(k) bonus depreciation (Ind. Code §6-3-1-33), and under Senate Enrolled Act 243 (2026) Indiana extended the decoupling to §168(n) qualified production property. Federal bonus depreciation is added back on the Indiana return, and property depreciates via regular MACRS on the state return.
Federal Deduction Is Where the Money Is
Indiana’s Tax Landscape: Why Cost Segregation Matters Here
Individual Income Tax
2.95% flat for 2026 (per Indiana DOR), scheduled to decrease to 2.90% for 2027. Indiana counties levy separate local income taxes (ranging 0.5% to ~3.4%) that are stacked on top of the state rate.
Corporate Income Tax
4.9% flat, one of the lower corporate rates in the Midwest.
Bonus Depreciation Conformity
Decoupled. Indiana has long disallowed federal §168(k) bonus depreciation (Ind. Code §6-3-1-33). Under Senate Enrolled Act 243 (2026), Indiana extended the decoupling to §168(n) qualified production property (per Indiana DOR Information Bulletin #118, effective July 4, 2025). Federal bonus depreciation is added back on the Indiana return; property depreciates via regular MACRS.
§179 Expensing
Indiana caps §179 at $25,000, significantly below the federal 2026 $2.56M cap. Federal §179 amounts above $25,000 require an Indiana addback in Year 1, with subsequent-year recovery.
Property Tax
~0.76% effective on owner-occupied housing (Tax Foundation 2026). Indiana’s constitutional property tax caps limit rates to 1% for homesteads, 2% for residential rental and agricultural property, and 3% for commercial and industrial property (as a percent of assessed value). A separate lever from income tax.
§481(a) Catch-Up
For Indiana 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 Indiana
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 Indiana specifically, the federal Year 1 savings apply fully; the Indiana state benefit is spread across the useful life of the reclassified components under regular MACRS (no state-level bonus stacking).

Cost Segregation in Indiana
Frequently Asked Questions
Does Indiana conform to federal bonus depreciation rules?
No. Indiana has long decoupled from federal §168(k) bonus depreciation (Ind. Code §6-3-1-33). Under Senate Enrolled Act 243 (2026), Indiana extended the decoupling to §168(n) qualified production property. Federal bonus depreciation is added back on the Indiana return; property depreciates via regular MACRS. Your federal Year 1 tax savings from a cost segregation study are fully preserved.
How does Indiana’s flat income tax interact with a cost segregation study?
Indiana has a flat 2.95% individual income tax for 2026 (scheduled to decrease to 2.90% in 2027) and a 4.9% flat corporate income tax. Indiana counties levy separate local income taxes on top of the state rate. Because Indiana decouples from federal bonus depreciation, the state-level Year 1 benefit is limited relative to conformity states. However, the reclassified MACRS depreciation still reduces Indiana taxable income faster than the default 39-year or 27.5-year schedule would.
What about Indiana’s §179 cap?
Indiana caps §179 at $25,000, significantly below the federal $2.56M cap for 2026. Federal §179 amounts above $25,000 require an Indiana addback in Year 1, with subsequent-year recovery. This affects the timing but not the total Indiana benefit for property that qualifies for §179 treatment.
What Indiana commercial property types benefit most from cost segregation?
What Indiana commercial property types benefit most from cost segregation?
Can I do a cost segregation study on an Indiana 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 Indiana manufacturing and industrial properties.
How do you do a cost segregation study on an Indiana 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 Indiana 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 Indiana 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. Indiana’s manufacturing expansion pipeline (Subaru, Toyota, Honda, Rivian-adjacent auto parts), Indianapolis life sciences growth, and Indianapolis-suburb multifamily development have produced substantial newer property in the ideal window.
Does Indiana’s property tax rate affect the cost seg decision?
Not directly. Cost segregation reduces income tax through accelerated depreciation, not property tax. Indiana’s effective property tax rate is around 0.76% (Tax Foundation 2026), and Indiana’s constitutional property tax caps (1% homestead, 2% rental/ag, 3% commercial/industrial) provide predictability. Property tax is a separate lever from the income-tax benefit cost segregation delivers.
What documentation do you need for an Indiana 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 Indiana decouples from federal bonus depreciation and caps §179 at $25K, your CPA will need the detailed asset schedule to maintain the Indiana MACRS calculation and §179 adjustment. We provide it as part of the standard deliverable.
Can you handle Indiana multi-property portfolios?
Yes. We regularly run cost segregation studies across multi-state and Indiana-only portfolios. Common for Indianapolis-metro multifamily portfolios, manufacturing operators with multiple Indiana facilities, and logistics operators with distribution centers along I-65/I-70. Typical study timeline is 4–8 weeks per property; complex manufacturing facilities take longer proportional to the equipment-cataloging effort.
