Project Overview & Estimated Benefits

How Cost Segregation Helps
—

Why This May Be a Good Fit
—

What This Estimate Shows Based on available information and preliminary assumptions, approximately — to — of the property may be reclassified into shorter‑life assets eligible for accelerated depreciation. If a study were completed and applied in tax year —, the estimated Year‑1 income tax savings for — would be approximately — to —. Of that amount, — to — reflects the estimated increase over standard straight‑line depreciation for —.

How We Support the Process
—

If you’d like, we can prepare a formal proposal to quantify and document the opportunity through an engineering‑based cost segregation study.

Note: This is a preliminary planning estimate based on the inputs provided and high‑level assumptions. Final allocations, depreciation schedules, and any filing approach should be confirmed through a formal study and reviewed with your CPA or tax advisor.

Note: Accelerated Depreciation Deduction values include bonus depreciation (if applicable), accelerated MACRS on short‑life property, and remaining straight‑line depreciation on long‑life property. “Increase in Deduction …” is Accelerated minus Straight‑Line. “Total Tax Savings …” is the estimated tax benefit from that increase based on the Effective Income Tax Rate. Tax savings reflect the estimated income tax benefit realized in the tax year shown (the year accelerated depreciation is applied), calculated using the effective tax rate applied for this estimate. If applicable, this includes any one-time catch-up adjustment taken in the Change Year. Rule-of-Thumb Estimate — Not a Formal Engineering Study. Allocation percentages are modeled ranges calibrated to IRS Audit Technique Guide (Pub. 5653) benchmarks and published study data. The IRS ATG explicitly identifies rule-of-thumb approaches as the least reliable cost segregation methodology, subject to greater IRS scrutiny than engineering-based studies. Final tax benefits depend on a formal engineering-based cost segregation study, detailed asset classification, applicable tax law, and the taxpayer’s specific circumstances. This estimate should not be used as the basis for filing tax returns or as a substitute for professional tax advice.

Estimator Assumptions & Methodology

⚠ Rule-of-Thumb Estimate — Important Limitations
The IRS Audit Technique Guide (Pub. 5653) explicitly identifies rule-of-thumb approaches as the least reliable cost segregation methodology and notes they are subject to greater IRS scrutiny. This estimate uses allocation percentages calibrated to IRS ATG benchmarks and published industry study data. It is provided for prospect qualification and feasibility planning only — not as a basis for filing tax returns or replacing an engineering-based cost segregation study.

Depreciable Basis

Purchase/Project Cost − Land + Capitalized Improvements
Land is non-depreciable

1031 / Carryover Basis

Carryover basis remains depreciable
Carryover basis is generally not bonus-eligible
This estimate models carryover as long-life basis (conservative)

Allocation Approach

Rule-of-thumb ranges calibrated to IRS ATG benchmarks and published study data — not an engineering-based study; the IRS identifies rule-of-thumb as the least reliable cost segregation methodology
Scenarios (Low/Med/High) reflect conservative to more accelerated assumptions
Basis is split into 5-year, 15-year, and 27.5/39-year property

Bonus Depreciation

Applied only to new 5-year and 15-year property when available
Not applied to 1031 carryover basis

Year 1 Depreciation

Bonus (if applicable) + MACRS on 5/15-year remainder
Straight-line on long-life (27.5 or 39 years)
Compared to a straight-line baseline for the same life

Prior Depreciation / Method Change (If Selected)

Shows incremental acceleration assuming prior straight-line depreciation was claimed
Actual reporting may vary based on prior schedules and conventions

Tax Rate

Uses Federal + State combined rate (simplified; ignores deductibility/limitations)

Note: Results are rule-of-thumb estimates for prospect qualification and planning. Actual allocations require a formal engineering-based cost segregation study and will vary based on property-specific components, documentation, and applicable tax law.

Important Notes: This is a rule-of-thumb estimate for prospect qualification and planning only. Allocation percentages are calibrated to IRS ATG benchmarks and published study data, but have not been validated against an engineering inspection of this specific property. The IRS Audit Technique Guide (Pub. 5653) identifies rule-of-thumb cost segregation approaches as the least reliable methodology and subject to greater scrutiny.

Actual asset classifications, depreciation schedules, and tax outcomes are determined through a formal engineering‑based cost segregation study and may vary based on property specifics, documentation, and applicable tax law. Tax laws and bonus depreciation provisions are subject to change.
