Cost segregation data for Manhattan, NY investors
Interquartile range across 50 engine-modeled property scenarios matched to the Manhattan, NY investor profile. Year-1 savings shown are the federal benefit (37% + 3.8% NIIT). This state does not conform to federal bonus depreciation, so the state share is not accelerated; it recovers over standard MACRS.

Year-1 savings shown are the federal benefit only (37% + 3.8% NIIT). This state does not conform to federal §168(k) bonus depreciation, so the state share is deferred over standard MACRS rather than realized in Year 1; the federal benefit is unaffected. Confirm specifics with your CPA.
Tax law current as of May 2026. Federal: OBBBA restored 100% bonus depreciation under §168(k), permanent for property placed in service on or after January 20, 2025 (property placed in service January 1–19, 2025 remains at 40% under the prior phase-down); 2026+ stays 100%. State conformity varies; verify with your CPA.
If you live in Manhattan, your combined federal + state + city tax bracket can reach ~54.3% — the highest in the country. Cost segregation on an out-of-state short-term rental converts that bracket into Year-1 cash savings, with the federal+NIIT portion alone producing significant returns even before the state-and-city stack adds on.
- $158,000 Accelerated Depreciation (typical STR worked example)
- $64,000 Est. Year-1 federal tax savings (37% + 3.8% NIIT; NY/NYC portion deferred over MACRS)
- 64x Return on Study Cost

Who are Manhattan cost segregation investors?
Manhattan’s cost-seg buyer pool clusters around four W-2 archetypes that dominate the borough’s economy:
- Finance (Goldman Sachs, JPMorgan, Citi, Morgan Stanley, hedge funds, private equity — MD and Partner level) — $500K–$3M+ base + bonus
- BigLaw (Cravath, Skadden, Wachtell, Kirkland, Sullivan & Cromwell — Partner and senior counsel) — $600K–$5M+
- Medicine (NYU Langone, Mount Sinai, Columbia, Memorial Sloan Kettering — attending physicians, surgeons, department heads) — $400K–$1.5M+
- Senior tech and media (Google NYC, Meta NYC, Bloomberg, NYT — VP and Director level) — $400K–$1.2M with RSU
The combined marginal-rate stack:
- Federal: 37%
- NIIT: 3.8%
- New York State: 9.65%
- New York City: 3.876% (resident tax — applies to all Manhattan ZIPs)
- Combined: ~54.3%
Manhattan residents pay the highest combined rate of any major metro in the country. The cost-seg deduction’s per-dollar value is correspondingly highest — every $1 of accelerated depreciation reduces Manhattan tax liability by ~$0.543.
Verify with your CPA — combined-rate math depends on filing status, AGI thresholds for NIIT, and the actual NY/NYC brackets your income lands in.
Why cost seg pays more if you live in Manhattan
A typical $500K–$1.5M out-of-state STR reclassifies 24–32% of basis under permanent 100% bonus depreciation. At the federal Year-1 rate (37% + 3.8% NIIT), every $1 of accelerated depreciation is worth ~$0.408 in Year-1 cash savings federally.
For a Manhattan finance VP at the top bracket, $158K of accelerated depreciation produces ~$64K in federal Year-1 tax savings. New York does not conform to federal §168(k) bonus depreciation, so the NY state and NYC city share of the deduction is deferred over standard 5/7/15-year MACRS rather than taken in Year 1; the federal Year-1 benefit is unaffected. See New York bonus depreciation. A Texas-based investor at the same federal bracket captures the same ~$64K federally but never picks up the deferred NY/NYC share.
The NIIT consideration: at top brackets, the 3.8% NIIT applies to passive investment income. STR property qualifying as a non-rental trade or business under Reg. §1.469-1T(e)(3)(ii) (7-day average stay + material participation) becomes non-passive — typically removing NIIT exposure on the rental side.
Where do Manhattan investors buy property?
Manhattan investors do not buy NYC property for STR — Local Law 18 + co-op board restrictions + Manhattan condo HOA rules effectively kill the Manhattan Airbnb thesis. Capital flows to vacation-resort markets within a flight or short drive:
- Smoky Mountains (Pigeon Forge, Gatlinburg) — Tennessee 0% state tax, cabin STR market, family-vacation demand.
- 30A / Destin, FL — Florida 0% state tax, premium beachfront.
- Joshua Tree / Palm Springs, CA — Desert STR.
- Maui, HI — Premium Pacific STR; direct flight from JFK.
- The Hamptons — Premium summer STR; local STR rules tightening, underwrite carefully.
A real Manhattan investor’s worked example
A Manhattan finance VP earning $1.6M (mix of base + bonus + carried interest), residing in Tribeca, buys a 2BR 30A condo for $700K with $20K immediate FF&E refresh. After $175K in land, the $525K adjusted basis includes $63K in 5-year assets (appliances, smart-home, theater system, beach package, decorative lighting), $22K in 7-year assets (custom furniture, coastal-themed built-ins), and $73K in 15-year property (pool deck, hardscaping, fencing, beach-access lighting).
That’s $158K reclassified into accelerated depreciation in Year 1. At the federal Year-1 rate (37% + 3.8% NIIT), the federal tax savings come to roughly $64,000, about 64x the cost of the study. (The NY state and NYC city share of the deduction is deferred over MACRS, not taken in Year 1; see the note above.)
Who doesn’t qualify for cost segregation in Manhattan?
REPS (Real Estate Professional Status under IRC §469(c)(7)) requires 750+ hours and more than 50% of personal services in real estate — structurally impossible for a full-time Manhattan finance professional, BigLaw partner, or attending physician. The STR exception under Reg. §1.469-1T(e)(3)(ii) (7-day average + 100-hour material participation) is the only viable W-2 offset path.
The 100-hour material participation test means active management — communicating with guests, scheduling cleanings/repairs, managing the listing. A pure property-manager arrangement doesn’t qualify — management hours must come substantially from the owner.
Frequently Asked Questions
How much does a cost segregation study cost in Manhattan? For a typical $700,000 Manhattan investment property, a Cost Seg Smart study runs $995. Full pricing: $495 (under $300K), $895 ($300K–$700K), $995 ($700K–$1M), $1,295 ($1M–$1.5M), $1,595 ($1.5M–$2M), $1,995 ($2M–$3M), $2,495 ($3M–$4M), $3,995 ($4M–$6M), $5,995 ($6M–$8M), $7,995 ($8M–$10M). Commercial and 5+ unit multifamily studies start at $1,995; 2–4 unit multifamily from $795. All studies delivered in under one hour with the CPA-Ready Guarantee — full refund if your CPA can’t use the report.
Can I cost-seg my Manhattan investment condo? For LTR, yes — Manhattan condos qualify for cost-seg at the 27.5-year residential schedule with 18–22% typical reclass. The deduction can offset passive income or qualify under REPS-via-spouse. For STR — Local Law 18 (NYC short-term rental restrictions) effectively prevents STR operation in Manhattan, so the Reg. §1.469-1T(e)(3)(ii) STR exception isn’t available locally.
Does NIIT apply to my STR income? NIIT (3.8%) applies to passive investment income. If your STR qualifies as a non-rental trade or business under Reg. §1.469-1T(e)(3)(ii) with material participation, the rental income (and the offsetting losses from cost seg) become non-passive — the NIIT exposure typically drops or disappears on the rental side. Verify with your CPA.
Does New York State conform to federal bonus depreciation? No. New York does not conform to federal §168(k) bonus depreciation. The federal Year-1 deduction is fully available; the New York state share is not accelerated and recovers over standard 5/7/15-year MACRS (deferred, not lost). Confirm specifics with your CPA.

How should Manhattan, NY investors choose a cost segregation provider?
For a Manhattan, NY investor buying a property in the $700,000 range, the choice of study provider is the single biggest controllable variable in the ROI. The methodology is fixed by IRS Audit Techniques Guide rules (industry-standard construction cost data, MACRS classification, engineering-based component reclassification) — what varies is delivery cost and turnaround time.
Traditional engineering studies often run several thousand dollars and can take several weeks, because they include on-site inspections, sales discovery calls, and scheduling overhead. The IRS Cost Segregation Audit Techniques Guide does not require a physical site visit; it requires engineering-based classification with industry-calibrated cost derivation and component-level documentation.
Modern automated providers (such as Cost Seg Smart) deliver the same IRS ATG–aligned study for $495–$1,595 in under one hour, using satellite imagery, county assessor data, and the same industry-standard construction cost databases. For a Manhattan, NY investor at the metro's combined bracket, that cost delta typically exceeds the study cost itself by several times over. The CPA-Ready Guarantee (full refund if the report can't be used by your CPA) plus the 60-day money-back policy makes the decision essentially risk-free on the report itself.
The automated path is best-fit for Manhattan, NY investors who: own residential STR property valued under $2M, are comfortable uploading closing docs + property photos online (no in-person visit required), and want the report in time to file the current year's return rather than the next one.
