About the Author
This analysis was prepared by Matthew Gigantelli, a cost segregation engineer who has personally completed engineered studies on over 3,000 properties across all 50 states. Gigantelli holds a B.A. in Finance (summa cum laude) from Rasmussen University and a certification from Boon Tax Educators (2026).
Matthew Gigantelli on geographic pricing: "I have completed studies on properties in 48 states. A standalone single-family rental in California requires the same engineering analysis as one in Ohio — the same component identification, the same MACRS classifications, the same report format. The only thing that changes is the property address. Any firm that charges more based on your state is pricing on local real estate values, not engineering effort."
Key Takeaways
- Cost segregation study pricing should not vary by state. The engineering methodology — component identification, cost estimation, MACRS classification — is identical regardless of property location.
- Some traditional firms charge 20–40% more in high-cost markets (California, New York, Massachusetts) because their pricing is tied to property values or local overhead — not engineering hours.
- AI-native providers maintain consistent national pricing because their cost structure is not tied to local real estate markets or regional office overhead.
- While study pricing should be location-independent, state tax implications vary significantly. Several states do not conform to federal bonus depreciation, which affects the total tax benefit (though not the study cost).
- The most important geographic factor is not study cost — it is state tax conformity. Investors in non-conforming states (California, New York, New Jersey, Pennsylvania, and others) should understand how state depreciation rules affect their total benefit.
Why Study Pricing Should Be the Same Everywhere
The Engineering Work Is Identical
A cost segregation study on a standalone single-family rental involves the same process regardless of location:
- Data collection: Property records, imagery, construction data, owner-provided photos
- Component identification: Flooring, cabinets, appliances, specialty electrical, site improvements
- Cost estimation: RS Means construction cost data (adjusted for regional cost factors — but this is a database lookup, not additional engineering)
- MACRS classification: IRC §168, Treasury Regulations, and case law apply uniformly across all states
- Report generation: Depreciation schedules, methodology documentation, audit defense
None of these steps change based on whether the property is in Texas or Massachusetts. The components in a 2,000 sqft SFR are the same. The MACRS classifications are the same. The IRS ATG standards are the same.
Why Some Firms Charge More in Certain States
Traditional firms that price based on property value inherently charge more in high-cost markets:
| State | Median Home Price (2026) | Traditional Study Fee (Value-Based) | AI-Native Fee (Complexity-Based) |
|---|---|---|---|
| California | ~$750,000 | $6,000–$10,000 | $1,800 |
| New York | ~$650,000 | $5,500–$9,000 | $1,800 |
| Massachusetts | ~$600,000 | $5,000–$8,500 | $1,800 |
| Texas | ~$350,000 | $3,500–$6,000 | $1,800 |
| Ohio | ~$225,000 | $2,500–$5,000 | $1,800 |
| Tennessee | ~$350,000 | $3,500–$6,000 | $1,800 |
A California investor pays 2–4x more than an Ohio investor for the same engineering work — because the traditional firm's pricing formula is tied to property value, not property complexity.
AI-native providers charge the same $1,800 for a standalone SFR in every state because the fee is based on asset class and building size — the factors that actually drive engineering hours. For the full pricing breakdown by property type, see our cost segregation pricing benchmarks.
What DOES Vary by State: Tax Implications
While study pricing should be location-independent, the tax benefit of cost segregation varies by state because of differences in state tax conformity with federal depreciation rules.
State Bonus Depreciation Conformity
The most significant state-level variable is whether the state conforms to federal bonus depreciation. States that do not conform require investors to add back the bonus depreciation on their state return and claim regular MACRS depreciation instead.
| Conformity Status | States | Impact on Cost Seg Benefit |
|---|---|---|
| Full conformity (follows federal bonus depreciation) | Most states, including TX, FL, TN, NV, WA, WY, SD, AK, NH (no state income tax states are effectively conforming) | Full federal + state benefit |
| Partial conformity (conforms with modifications) | Several states with varying rules | Reduced state-level benefit; federal benefit unchanged |
| Non-conforming (does not allow bonus depreciation) | CA, NY, NJ, PA, and others (varies by year) | No state bonus depreciation; must use regular MACRS on state return; federal benefit unchanged |
Critical point: Non-conformity affects the state tax benefit only. The federal benefit of cost segregation is identical regardless of state. An investor in California receives the same federal tax savings as an investor in Texas — the difference is that the California investor may not receive additional state-level bonus depreciation savings.

No-Income-Tax States
States with no individual income tax (Texas, Florida, Tennessee, Nevada, Washington, Wyoming, South Dakota, Alaska, New Hampshire) provide no state-level depreciation benefit — but also impose no state-level depreciation recapture. The cost segregation benefit is purely federal, which simplifies the analysis.
High-Income-Tax States
Investors in high-income-tax states that conform to federal bonus depreciation receive the largest total benefit:
| State | Top State Rate | Federal Rate | Combined Rate | Year-1 Savings on $750K SFR |
|---|---|---|---|---|
| California (non-conforming) | 13.3% | 37% | 37% federal only | ~$53,300 (federal) + $0 state bonus |
| New York (non-conforming) | 10.9% | 37% | 37% federal only | ~$53,300 (federal) + $0 state bonus |
| New Jersey (non-conforming) | 10.75% | 37% | 37% federal only | ~$53,300 (federal) + $0 state bonus |
| Oregon (conforming) | 9.9% | 37% | 46.9% | ~$67,600 (federal + state) |
| Minnesota (conforming) | 9.85% | 37% | 46.85% | ~$67,500 (federal + state) |
| Hawaii (conforming) | 11% | 37% | 48% | ~$69,100 (federal + state) |
| Texas (no state tax) | 0% | 37% | 37% | ~$53,300 (federal only) |
Calculations assume $750,000 SFR, 20% land, 24% accelerated allocation, 100% bonus depreciation. State calculations are simplified; actual state treatment varies by entity type and filing status.
Investors in conforming high-tax states like Oregon, Minnesota, and Hawaii receive the highest combined benefit because state bonus depreciation amplifies the federal savings.
State-Specific Considerations
California
California does not conform to federal bonus depreciation. California investors claim regular MACRS depreciation on their state return (5-year and 15-year property depreciated over their full recovery periods, not expensed in Year 1). The federal benefit is unchanged. Given California's 13.3% top rate, the state-level depreciation still provides meaningful savings — just spread over the recovery period rather than concentrated in Year 1.

Florida and Texas
No state income tax. Cost segregation benefit is purely federal. These states are among the most popular for rental property investment, and the absence of state tax simplifies the cost segregation analysis — no state conformity issues, no state depreciation schedules, no state recapture.
Tennessee
Tennessee has no state income tax on earned income (the Hall Tax on investment income was fully repealed in 2021). Cost segregation benefit is purely federal. Tennessee is a major short-term rental market (Nashville, Gatlinburg, Pigeon Forge), making cost segregation particularly relevant for STR investors using the material participation loophole.
For Tennessee-specific guidance, see our Tennessee cost segregation STR tax guide.
New York
New York does not conform to federal bonus depreciation. New York investors must add back the bonus depreciation on their state return. However, New York allows a special depreciation deduction under Tax Law §606(a) that provides partial acceleration. The federal benefit is unchanged. Given New York's 10.9% top rate, the state-level impact is significant — consult a New York tax professional for the specific calculation.
The Bottom Line: Focus on Federal Benefit, Not State Study Pricing
The two most common geographic misconceptions about cost segregation:
-
"Studies cost more in expensive markets." They should not. Engineering effort is determined by property type and complexity, not location. If a provider charges more for a California SFR than a Texas SFR, they are pricing on property value — not work performed.
-
"Cost segregation does not work in non-conforming states." It works — the federal benefit is identical. Non-conforming states reduce the state-level bonus depreciation benefit, but the federal deduction (which is the majority of the savings for most investors) is unaffected.
The right approach: evaluate cost segregation based on the federal benefit, treat any state-level benefit as a bonus, and choose a provider that prices on property complexity rather than geographic location.

Frequently Asked Questions
Q: Does a cost segregation study cost more in California than Texas?
A: It should not. The engineering methodology is identical regardless of state. AI-native providers charge the same fee nationally ($1,800 for a standalone SFR in any state). Some traditional firms charge more in high-cost markets because their pricing is tied to property values — but this reflects their pricing model, not the actual engineering work required.
Q: Does cost segregation work in states with no income tax?
A: Yes. The federal tax benefit of cost segregation is identical regardless of state. In no-income-tax states (Texas, Florida, Tennessee, Nevada, etc.), the benefit is purely federal. There is no state-level depreciation benefit, but there is also no state-level recapture — simplifying the analysis.
Q: How does California's non-conformity affect cost segregation?
A: California does not allow bonus depreciation on the state return. California investors must use regular MACRS depreciation schedules for state purposes (5-year and 15-year property depreciated over their full recovery periods). The federal benefit — including 100% bonus depreciation — is unchanged. The state-level depreciation still provides savings, just spread over time rather than concentrated in Year 1.
Q: Should I factor state taxes into my cost segregation ROI calculation?
A: Yes, but the federal benefit alone justifies cost segregation for most properties. State-level benefits are a bonus in conforming states and are deferred (not lost) in non-conforming states. Use the free calculator for a property-specific estimate that accounts for your tax bracket.
Q: Do I need a state-specific cost segregation provider?
A: No. MACRS classifications are federal law and apply uniformly across all states. The engineering methodology does not change by state. What you may need is a CPA who understands your state's conformity rules for filing the state return. The cost segregation study itself is state-independent.
