1031 Exchanges in New York: Rules, Taxes, Insurance, and the Long Arc

A Shop 1031 research page. Reviewed 2026-06-03. Every claim sourced; sources collected at the foot of the page.

New York is a high-conformity state with a high-cost transactional surface, not a non-conforming state with hidden friction. The distinction matters because most of the casual framing around a New York 1031 starts with the assumption that the state will somehow tax the gain anyway, which is wrong, and ends without modeling the transfer-tax stack at closing, which is the actually material cost. New York fully conforms to the federal §1031 deferral framework through New York Tax Law §612, recognizes the deferral at the state level for residents and grants withholding relief to nonresidents through Form IT-2663, and does not pursue deferred New York-source gain after a cross-state exchange the way California’s claw-back does. The cost is concentrated at closing in the New York State real estate transfer tax, the New York City Real Property Transfer Tax for in-city transactions, and the mansion tax on residential acquisitions above one million dollars. Each of these is independently sourceable. Together they form the actual calculus a New York exchanger should run.

This page is the working guide. The federal §1031 floor, New York’s full conformity, the IT-2663 nonresident-withholding mechanic that catches non-New York residents selling New York real property, the transfer-tax stack at closing, the Class 1-4 property tax assessment structure that distinguishes residential from commercial in New York City, the post-Sandy coastal insurance dynamics, the demographic story including the renewed 2025 population decline, and the unique considerations a New York exchanger should clear before identifying replacement.

§1. 1031 mechanics in New York

The federal floor applies in New York the same way it applies in every other state. Internal Revenue Code §1031 permits the deferral of gain on the sale of real property held for productive use in a trade, business, or investment, provided the proceeds are reinvested into like-kind real property of equal or greater value through a Qualified Intermediary. Identification of replacement must occur within forty-five days of the relinquished closing; the replacement must close within one hundred eighty days of the same event. The authorities are 26 U.S.C. §1031 and the implementing regulations at 26 C.F.R. §1.1031(k)-1, with operating guidance in IRS Publication 544. ^{1 2 3}

New York fully conforms to the federal §1031 treatment at the state level. The conforming provision is New York Tax Law §612, which establishes that New York taxable income for individuals is computed by reference to federal adjusted gross income, with specified state-level modifications that do not include a §1031 modification. A properly executed exchange that defers gain federally defers it for New York state income tax purposes at the same time, and the deferral applies whether the replacement property is located in New York or in another state. There is no California-style claw-back. Once New York grants the deferral, it does not pursue the deferred New York-source gain after a cross-state exchange. This is a meaningful distinction for the New York-to-Florida and New York-to-Texas migration patterns that have shaped New York exchange capital flows since the pandemic. ^{4 5}

The state-specific mechanic that catches every nonresident sale of New York real property is Form IT-2663, the Nonresident Real Property Estimated Income Tax Payment Form. Under New York Tax Law §663, a nonresident transferring New York real property must file IT-2663 before the deed is recorded and is generally required to remit an estimated income tax payment at the highest New York personal-income tax rate, currently 7.7 percent, on the gain. For §1031 exchanges, the form provides an exemption: the seller checks Box 4B (Section 1031 like-kind exchange), provides a brief summary, and remits no estimated tax. The exemption requires the deferred exchange to be in place with the Qualified Intermediary at the time of recording, which means coordination between the QI, the title company, and the seller’s representative is required before the deed crosses the recording counter. Missed IT-2663 paperwork at recording produces the same operational complication as missed Form 593 paperwork in California: surprise withholding at close, complicated QI handling, and a refund-claim process to recover the withheld amount. ^{5 6}

The transfer tax mechanics are where the New York transaction cost is concentrated. New York State imposes a real estate transfer tax under New York Tax Law §1402 at $2 per $500 of consideration, or 0.4 percent. On a $5,000,000 transaction, the state transfer tax is $20,000. New York City imposes a separate Real Property Transfer Tax (RPTT) under Chapter 21 of Title 11 of the New York City Administrative Code. For residential property, the RPTT rate is 1.0 percent on consideration of $500,000 or less and 1.425 percent above that threshold. For commercial property and other non-residential transfers, the RPTT rate is 1.425 percent on consideration of $500,000 or less and 2.625 percent above that threshold. On a $5,000,000 New York City commercial acquisition, the combined state-plus-city transfer tax is approximately 3.025 percent of consideration, or $151,250, before recording fees and title insurance. The transfer tax is paid by the grantor (seller) by statute, though buyers often assume the obligation by contract in markets where the convention has shifted. ^{7 8 9}

The mansion tax under New York Tax Law §1402-a applies to residential conveyances of consideration of $1,000,000 or more, in graduated brackets running from 1.0 percent at the $1,000,000 threshold to 3.9 percent on consideration of $25,000,000 or more. The mansion tax is paid by the grantee (buyer). It applies only to residential property, including co-ops, condominiums, and one-to-three-family homes; it does not apply to commercial property. For a 1031 exchanger acquiring a multifamily residential property above the threshold, the mansion tax is a closing-side cost the offer price should absorb. ¹⁰

New York imposes no state-level registration or bonding regime on Qualified Intermediaries. Federal §1031 rules apply. The buyer should confirm independently that the QI carries fidelity bonding and errors-and-omissions coverage proportionate to the transaction size.

New York is an attorney-state for real estate closings. Both buyer and seller typically engage New York-licensed counsel, and counsel attends the closing. This is structurally different from the title-and-escrow model of California, Texas, and Florida. The attorney-state convention adds to closing costs but reduces the operational gap between the contract language and the recorded outcome. The TP-584 (state transfer-tax return) and TP-584-NYC (city transfer-tax return) are filed with the deed at recording.

§2. Property tax in New York

New York’s property tax system varies substantially by jurisdiction, with the New York City structure operating on a different statutory basis than the rest of the state. Statewide, effective property tax rates run in the upper third nationally, with significant geographic dispersion across Long Island (Suffolk and Nassau counties), Westchester, the Hudson Valley, upstate, and New York City itself. The governing statute outside New York City is the New York Real Property Tax Law (RPTL); within New York City, RPTL Article 18 establishes the special class-based assessment system administered by the New York City Department of Finance. ^{11 12}

The New York City Class 1-4 structure is consequential for 1031 exchangers. Class 1 covers one-to-three-family homes and is governed by separate assessment caps. Class 2 covers residential rental, cooperative, and condominium properties, subdivided into Class 2A (4-6 units), Class 2B (7-10 units), Class 2C (cooperatives or condominiums of 3-10 units), and Class 2 large properties (11+ units). Class 3 covers utility properties. Class 4 covers all other commercial property: office, retail, hotel, industrial, warehouse, gas station, parking lot, and most large vacant lots. Class 2 small properties (2A, 2B, 2C) are subject to a beneficial assessment cap of 8 percent annual increase and 30 percent over five years. Class 2 large properties and Class 4 properties have no assessment cap, but benefit from a transitional assessment system that phases in any change to assessed value (whether increase or decrease) over five years at 20 percent per year. ¹³

The transitional assessment system is the most commonly missed item in cross-state replacement underwriting on New York City Class 4 commercial property. A property whose just value rose 15 percent in the year before acquisition is still phasing in that change over five years, which means the year-of-acquisition assessed value can lag market value materially. The exchanger inherits the phase-in schedule, which can compress in the buyer’s favor (if values declined recently) or expand against the buyer (if values rose recently). Modeling the property-tax line from the just value alone, without the transitional adjustment, will either overstate or understate the cash tax bill for several years.

Outside New York City, the property tax base is administered at the county and town level, with the New York State Office of Real Property Tax Services overseeing the assessment process. The STAR program provides limited state-funded relief for owner-occupied residential property and is not relevant to investment property. The municipal tax base varies sharply: Westchester and Long Island carry some of the highest effective rates in the United States; many upstate municipalities run lower effective rates against a lower base.

Harlow’s note on unit economics. On a $5,000,000 New York City Class 4 commercial acquisition, year-one property tax depends meaningfully on the transitional assessed value schedule the property carries at acquisition rather than the just value at acquisition. The lookup is mechanical (the NYC Department of Finance publishes the schedule per property), but the cash difference between just value and transitional value can run 10 to 25 percent on a recently appreciated property. Model the year-one cash tax from the transitional roll, not from the assessment-ratio-adjusted just value. Outside New York City, on a $5,000,000 Westchester or Long Island commercial acquisition at the local effective rate, expect year-one tax in the range of $90,000 to $130,000, with a sharper response to local school-district budget cycles than in most other states.

§3. Property insurance in New York

New York’s property insurance market sits between the structural pricing of the Gulf and Atlantic hurricane-exposed markets and the lower-loss-profile northern markets. The dominant catastrophe exposure is named storms, with Hurricane Sandy in 2012 setting the modern benchmark for downtown Manhattan, Brooklyn waterfront, Queens, and the Long Island south shore. Nor’easter exposure, ice-storm exposure, and an increasing convective-loss signal across upstate New York have repriced reinsurance into the state since 2022, though not at the magnitude of the Gulf Coast repricing.

The state’s insurer of last resort for property in designated coastal areas is the New York Property Insurance Underwriting Association (NYPIUA), established under New York Insurance Law §5301 and administered through the New York State Department of Financial Services. NYPIUA writes coastal residential and commercial property in the wind tier that the private market declines to underwrite. The exposure footprint is smaller than Florida Citizens or California’s FAIR Plan, but the operating mechanics are analogous: NYPIUA acts as the backstop when private capacity is unavailable and policyholders typically pay a premium above private market rates for that backstop. ¹⁴

Flood exposure is a distinct line. The National Flood Insurance Program under FEMA Risk Rating 2.0 has materially repriced coastal New York flood premiums since 2021, with the largest movements in the Sandy-affected zones. Commercial property above the NFIP $500,000 cap layers private excess flood coverage, and the layered structure is now common on any waterfront acquisition in Manhattan, Brooklyn, Queens, Staten Island, and the Long Island south shore. ¹⁵

For inland New York commercial property (most of the Hudson Valley, Capital Region, Western New York, the Southern Tier), the catastrophe overhead is lower and the market is more functional. Carriers underwrite property-by-property with attention to age of stock (much of New York’s commercial inventory predates 1980), sprinkler status, and roof condition. Earthquake exposure exists in a localized way along the Ramapo Fault but is not a primary line.

Harlow’s note on unit economics. For a $5,000,000 New York inland commercial property underwritten today, expect property-insurance expense in the range of 0.4 to 0.8 percent of insured value, or roughly $20,000 to $40,000 annually. For coastal New York City and Long Island commercial property within the wind tier and a named-storm zone, the range can run materially higher (0.7 to 1.5 percent of insured value), with a separate excess flood policy commonly an additional 0.1 to 0.3 percent. Bind from a quote, not a national-average assumption.

§4. Demographic trends

New York’s population stood at approximately 19.8 million as of 2025 Census estimates, with the state recording a net gain of approximately 1,076 residents in the year ending July 1, 2025. The 2025 small positive at the state level masks renewed decline at the New York City level, where the city lost approximately 12,000 residents in the same period, reversing post-pandemic gains of 70,000 in 2023 and 163,000 in 2024. The dominant underlying mechanic is reduced international migration combined with continued domestic out-migration to lower-cost states, particularly Florida, Texas, the Carolinas, and Georgia. ^{16 17}

The domestic out-migration figures are the longer trend. Between 2019 and 2023, New York City recorded a net loss of approximately 286,000 residents to other parts of New York state, 192,000 to New Jersey, 106,000 to Florida, 62,000 to Pennsylvania, and 51,000 to Connecticut. The migration to Texas was smaller in absolute terms but skewed toward higher-income migration, with Texas posting a $2 billion net adjusted gross income gain from former New York City residents during the same five-year window. The Florida outflow accounted for roughly $14 billion in adjusted gross income over the same period. The capital flow tracks the population flow, and the dominant cross-state 1031 exchange destinations for New York exchangers mirror these out-migration corridors. ¹⁷

Median household income in New York was approximately $84,000 in 2024 per Federal Reserve-published Census American Community Survey estimates, with extreme geographic concentration in New York City, Westchester, Nassau, and the Hudson Valley wealthy corridors at multiples of the state median and clusters below the state median in much of upstate New York. The Bureau of Economic Analysis reports New York per-capita personal income among the highest in the country. ^{18 19}

The major New York metropolitan markets relevant to 1031 exchangers are New York-Newark-Jersey City (approximately 19.6 million population including New Jersey and Connecticut suburbs), Buffalo-Cheektowaga (approximately 1.1 million), Rochester (approximately 1.1 million), Albany-Schenectady-Troy (approximately 900,000), and Syracuse (approximately 650,000). Each carries a distinct asset-class profile. New York City concentrates institutional office, multifamily, retail, and hospitality with the deepest global buyer pool in the country; Westchester and Long Island are the dominant suburban multifamily and industrial markets; Buffalo and Rochester are the upstate value plays across all major asset classes; Albany serves the state-government and life-sciences corridors. Long Island industrial and the Hudson Valley distribution corridor (driven by proximity to the New York City consumption zone) are the deepest non-coastal industrial absorption markets in the state.

§5. Unique legal and financial considerations

Several New York-specific considerations sit outside the headline tax and insurance pictures, and each is worth surfacing before an exchanger identifies New York replacement.

The first is the drop-and-swap structure for partnership-owned New York real property. A drop-and-swap occurs when partners in a partnership owning real property liquidate their partnership interests for tenants-in-common (TIC) interests in the property before the sale, allowing each former partner to execute a separate §1031 exchange on their TIC interest. New York courts and the New York Department of Taxation and Finance have, in recent administrative decisions, accepted properly structured drop-and-swap transactions on the New York state side, though the federal treatment under IRS guidance carries its own constraints. For partnership-owned New York real property where partners want divergent post-sale outcomes, the drop-and-swap is the standard structuring tool and should be run with New York-licensed counsel well before the relinquished close. ²⁰

The second is the New York City commercial property abatement regime. The Industrial and Commercial Abatement Program (ICAP), formerly the Industrial and Commercial Incentive Program (ICIP), under New York City Administrative Code §11-271 provides partial real property tax abatement for qualifying renovation and new construction of industrial and commercial property. The 421-a program (now expired for new entrants but with phase-out tails on existing certificates) provided multifamily incentives; the J-51 program (also being phased out) provided rehabilitation incentives. For an exchanger acquiring New York City property with an existing abatement certificate, the abatement period and any post-acquisition compliance burdens belong in the due-diligence checklist. ²¹

The third is the rent stabilization regime. Approximately one million rental units in New York City are subject to rent stabilization under the Rent Stabilization Law and the Emergency Tenant Protection Act. The 2019 Housing Stability and Tenant Protection Act materially constrained rent increases, vacancy decontrols, and major capital improvement pass-throughs. For an exchanger acquiring rent-stabilized multifamily property, the cap on rent growth and the constraint on conversion to market rents materially affect the underwriting. The DHCR (New York State Division of Housing and Community Renewal) administers rent stabilization compliance. ²²

The fourth is the New York LLC ownership disclosure requirement for residential property. Under New York Tax Law §1409(a) and related provisions, the TP-584 transfer-tax return now requires disclosure of LLC members for residential property transfers, intended to address anonymous ownership in luxury New York City residential. The disclosure does not apply to commercial property in the same form, but the residential disclosure does affect 1031 acquisitions structured through LLC vehicles.

The fifth is the cooperative ownership structure for residential property in New York City. A New York City cooperative is technically a transfer of shares in a corporation that owns the underlying real property, not a transfer of real property itself. The §1031 treatment of cooperative interests has been confirmed in IRS guidance for residential cooperatives, but the mechanics of identification, QI custody, and transfer-tax assessment differ from a fee simple transfer. The RPTT applies to cooperative transfers; the federal §1031 analysis applies; the operational coordination with the cooperative board is a separate diligence track.

§6. Closing summary and the work ahead

The New York 1031 exchanger is operating in a market with a clear set of distinguishing features. The federal floor applies; New York fully conforms and does not pursue deferred New York-source gain after a cross-state exchange; the IT-2663 nonresident-withholding obligation must be cleared at recording with the Box 4B exemption; the New York State transfer tax of 0.4 percent stacks with the New York City RPTT of 1.425 to 2.625 percent and, on residential acquisitions above one million, the mansion tax of 1.0 to 3.9 percent; the New York City Class 1-4 assessment system with the Class 2 small-property cap and the Class 2 large / Class 4 transitional five-year phase-in is meaningfully different from any other state’s property-tax mechanics; the coastal property insurance market repriced after Sandy and is repricing again after the 2022-2024 reinsurance cycle; the population is roughly flat at the state level but New York City has resumed declining; the dominant cross-state outflow is to Florida, Texas, the Carolinas, and other parts of New York state itself; commercial property carries abatement certificates and rent-stabilization compliance that must be diligenced; partnership-owned property can use drop-and-swap structuring with proper counsel; cooperatives carry their own §1031 mechanics. None of these is a reason to avoid a New York exchange. Each is a reason to underwrite one carefully. The jurisdiction-specific factors above are starting-point context. A state-experienced CRE professional will translate them into deal-specific judgment.

This is the question Shop 1031 was built to compress. Every New York offering memorandum on the platform is normalized to a single schema, underwritten at re-let to the buyer’s specific equity, debt, and DSCR floor, and ranked by Dark Shell Score. The buyer searches a pre-cleared field rather than reading offering memoranda to disqualify them. For a market with New York’s specific overlay, that compression is decisive because the variables that move outcomes (transfer-tax stack at closing, IT-2663 coordination at recording, the Class 4 transitional assessed value at acquisition, ICAP and 421-a abatement diligence, rent-stabilization analysis, cooperative versus condominium classification) are knowable in advance and frequently missed in conventional buy-side workflows.
