Cost segregation in New York.

New York is one of the highest-basis residential investor markets in the country. The five-borough condo + brownstone + small-multifamily market produces median rental property values of $1M–$3M+. Westchester, Long Island, and the Hamptons add high-end SFR + vacation rental layers. The Hudson Valley and Catskills add weekend-getaway STR markets in the $600K–$1.5M range. The combination produces federal cost segregation deductions among the largest in the country, but New York’s individual income tax has a high top marginal rate (10.9% state + ~3.88% NYC for residents) and its own depreciation treatment that may not match federal §168(k). The federal deduction is unaffected; the NY-side treatment is modeled separately by your CPA. Verify the current New York treatment with your CPA before filing. See Your New York Tax Savings →

How Cost Segregation Works in New York

Cost segregation reclassifies portions of your property’s depreciable basis into 5-year (FF&E, appliances, carpet), 7-year, and 15-year (land improvements) MACRS recovery periods. Reclassified components qualify for federal bonus depreciation under §168(k) in the year placed in service.

At the federal level, every $100K reclassified produces ~$37K of Year-1 federal tax savings at the 37% bracket. New York’s individual income tax adds a high state-side layer: the top marginal NY state rate is 10.9% (reached at ~$25M income for single filers; lower brackets at lower incomes), and NYC residents face an additional ~3.88% top city rate. However, New York has historically required modifications to federal income on the state return for accelerated depreciation, including bonus depreciation under §168(k), meaning the federal acceleration does not automatically flow dollar-for-dollar to the NY return. Your CPA will model the New York depreciation schedule alongside the federal one. Verify the current treatment with your CPA before filing. Whatever NY allows on the state side, the federal piece is unaffected.

Real Example — $1.85M Hudson Valley / Hamptons vacation rental:

• $1,850,000 purchase price
• $1,480,000 depreciable basis (excluding land)
• $360,000 accelerated depreciation (reclassified to 5/7/15-year MACRS)
• ~$133,200 estimated federal tax savings (37% bracket)
• New York state savings: modeled separately by your CPA based on current NY depreciation modification treatment

Representative New York Year-1 federal savings: $50,000 – $285,000 depending on basis.

What Investors in New York Should Know

Federal and NY state schedules are modeled separately. New York has historically required modifications on the state return to undo or adjust federal bonus depreciation, with the modifications generally reversing over the asset’s MACRS life. Plan for two depreciation schedules: federal MACRS with §168(k) acceleration, and a New York schedule reconciled by your CPA. The federal deduction is unaffected by the NY state-side treatment. Verify the current NY treatment with your CPA.

High basis is the norm in NY. Manhattan condo investors routinely face $1.5M–$5M purchase prices for investment-grade properties. Brooklyn brownstones and 2–4 unit properties run $1.5M–$4M. Westchester, Long Island North Shore, and the Hamptons routinely run $1.5M–$8M+. The absolute Year-1 federal deductions on a representative NY investment property are larger than on a representative property in most states, even before the state piece is layered in.

Condo basis is interior-only. Manhattan and Brooklyn investor markets are heavily condo-driven. Condo investors depreciate the interior of the unit only (flooring, casework, fixtures, appliances, FF&E), not the building shell or common areas. Reclassification percentages generally run 18–22% of depreciable basis on furnished condos. Cost segregation generally pencils for NYC condos above ~$700K purchase price given the high basis floor.

Coop ownership is structurally different from condo. NYC has a substantial coop investor market alongside the condo market. Coop owners hold shares in a corporation plus a proprietary lease (not a deeded real estate interest), and the building structure is owned by the corporation, not the shareholder. Cost segregation on coop units generally applies to interior improvements only (casework, flooring, fixtures, FF&E), with reclassification rates running 12–18% of the shareholder’s basis on furnished units. The coop-specific basis allocation requires CPA verification before filing.

Brownstone + 2–4 unit basis is full structure. Brooklyn brownstones, Harlem multifamily, and 2–4 unit converted properties offer full structural basis plus unit-count multiplication. Reclassification percentages generally run 20–26% of basis. The standout NY cost-seg play on a dollar-per-property basis.

Hudson Valley + Catskills weekend STR. Beacon, Hudson, Catskill, Phoenicia, Woodstock, Saugerties: the Hudson Valley + Catskills weekend rental market serves NYC + Boston second-home buyers and weekend renters. STR purchase prices generally $600K–$1.5M with farmhouse-aesthetic or modern-mountain furnishings. Federal acceleration produces $25K–$80K of Year-1 savings on typical properties.

Hamptons + Long Island North Shore. East Hampton, Sag Harbor, Bridgehampton, Montauk, Southampton: the Hamptons summer rental market produces some of the highest-basis vacation rental investments in the country ($2M–$15M+). The federal Year-1 deduction on a $5M Hamptons property routinely runs $300K–$500K. North Shore Long Island (Oyster Bay, Cold Spring Harbor) supports a parallel high-basis SFR investor market.

Westchester suburbs. Bronxville, Scarsdale, Rye, Larchmont, Chappaqua, Bedford: Westchester’s commuter suburbs support a high-basis SFR + small-multifamily investor market. NYC-commuter wealth drives demand for $1M–$4M family rentals.

STR permitting is a complex layer in NYC. Local Law 18 (NYC’s 2023 short-term rental crackdown) materially constrained sub-30-day rentals across the five boroughs. Whether your NYC property qualifies as a permitted STR affects material participation analysis under §469. The Hudson Valley, Catskills, Hamptons, and Long Island are not subject to Local Law 18. Resolve permitting with local counsel before purchase.

Multi-Property Investors and Form 3115 Lookback

A typical NY investor holds a Brooklyn brownstone or 2–4 unit small-multi plus a Hudson Valley or Catskills weekend property plus (for higher-net-worth households) a Hamptons summer rental. Properties acquired 2+ years ago without a cost segregation study qualify for Form 3115 lookback: the missed federal acceleration recaptures in a single tax year via §481(a). On a 3-property NY portfolio, the catch-up federal deduction routinely runs $300K–$800K depending on basis. Multi-property study bundles run 5%–15% off per property. See bundle pricing →

Key Markets in New York

Manhattan, NY

Manhattan’s condo investor market is one of the highest-basis residential markets in the country. Interior-only depreciation on premium FF&E and finishes produces meaningful reclassification on properties above ~$700K. The combination of high basis + NY’s high top marginal rate (10.9% state + 3.88% NYC = ~14.78% combined) makes accelerated deductions among the most valuable in any state; the federal piece is unaffected by NY state-side treatment. See Manhattan breakdown →

Brooklyn, NY

Brooklyn’s brownstone + 2–4 unit property market is the standout NY cost-seg play on a dollar-per-property basis. Full structural basis + unit-count multiplication + high property values produces Year-1 federal deductions in the $80K–$250K range on typical properties. Park Slope, Fort Greene, Bedford-Stuyvesant, Williamsburg, Crown Heights all support strong investor activity. See Brooklyn breakdown →

Westchester, NY

NYC-commuter SFR + small-multifamily investor market. Bronxville, Scarsdale, Rye, Larchmont, Chappaqua, Bedford support $1M–$4M+ family rentals. Westchester’s high property values produce strong federal accelerations; the NYC-commuter investor base skews high-income W-2 with STR-material-participation considerations on second properties. See Westchester breakdown →

Long Island + Hamptons, NY

Long Island North Shore (Oyster Bay, Cold Spring Harbor) supports a high-basis SFR investor market. The Hamptons (East Hampton, Sag Harbor, Bridgehampton, Montauk, Southampton) produce some of the highest-basis vacation rentals in the country. Federal Year-1 deductions on a $5M Hamptons property routinely run $300K–$500K. See Long Island breakdown →

Hudson Valley + Catskills

Beacon, Hudson, Catskill, Phoenicia, Woodstock, Saugerties: weekend / vacation rental economy serving NYC + Boston second-home buyers. Median STR purchase prices $600K–$1.5M with farmhouse-aesthetic or modern-mountain furnishings.

Property Types That Benefit Most in New York

Brownstones + 2–4 unit small multifamily: Brooklyn, Harlem, parts of Queens. Full structural basis + unit-count multiplication + high NYC property values. The standout NY play.

Condos: Manhattan, Brooklyn waterfront, Long Island City, NYC waterfront. Interior-only basis but at NYC price floors ($700K+) the interior FF&E + finishes still produce meaningful acceleration.

Single-family rentals: Westchester suburbs, Long Island North Shore, Westchester county SFR. NYC-commuter SFR + small-rental investor market.

Vacation rental STRs: Hamptons, Hudson Valley, Catskills. Highest-basis vacation rentals in the country (Hamptons) or modern-mountain Hudson Valley + Catskills inventory. Strong FF&E densities.

Mixed-use: Manhattan, Brooklyn, Queens. Ground-floor retail + residential upstairs is common in pre-1940 NYC inventory. The mixed-use 27.5yr + 39yr split produces meaningful reclassification on both components.

When Cost Segregation Typically Makes Sense in New York

It generally makes sense when:

• Purchase price above ~$700K for condos, ~$1M+ for SFR / brownstone / multifamily
• Property is furnished (STR) or has significant interior finishes / land improvements
• You materially participate in your STR operation (subject to NYC Local Law 18 permitting outside NYC)
• You’re a high-income W-2 earner who can use STR material participation to offset salary income; NY’s high combined federal + state + NYC rate makes this especially valuable
• You hold the property for 3+ years (depreciation recapture applies at sale: up to 25% on real-property gain, and ordinary rates on some personal-property components)
• Your CPA is comfortable maintaining a separate New York depreciation schedule with state-level modifications

It may not make sense if:

• Condo under ~$500K (interior-only basis may not justify study cost)
• Your NYC property is unpermitted for short-term rental use under Local Law 18 and can’t qualify for material participation
• You’re a passive investor with no other passive income
• You plan to sell within 12–18 months

CPA use note: These figures estimate the size of the depreciation deduction. Whether the loss is usable in the current year depends on passive-activity rules, STR material participation, REPS status, entity structure, depreciable basis, and state conformity. Your CPA decides how and when it is applied. Specialty and site components (equipment, casework, docks, pools, arenas, tenant improvements, and similar) are only classified when you own them and they are included in the depreciable basis being studied.
