Cost Segregation in New York: State Tax Rules (2026)

New York investors face a two-layer problem. The state decouples from federal bonus depreciation, and New York City imposes its own taxes on top for city residents and for unincorporated businesses operating in the city.

The study still works. But the state and city math diverges from the federal math immediately, and it stays divergent for the entire hold period.

New York Decouples From Bonus Depreciation

New York requires an addback of the federal bonus depreciation deduction under IRC Sec. 168(k) and a recomputation of depreciation as though the provision did not exist. A narrow exception has historically applied to certain property placed in service in designated zones.

For state purposes, reclassified components from a cost segregation study depreciate over their normal MACRS recovery periods. Five-year property over five years, 15-year land improvements over fifteen.

The reclassification is still worth a great deal at the state level, because moving basis from a 27.5-year or 39-year schedule to five and fifteen years accelerates recovery substantially even without bonus.

The consequence is a permanent divergence between federal and New York depreciation schedules and, eventually, between federal and New York basis. Both must be tracked separately.

New York City Adds Another Layer

New York City residents pay a city personal income tax on top of state tax, pushing combined marginal rates well above 14% at high incomes.

Separately, the city imposes the unincorporated business tax on the income of partnerships and sole proprietorships carrying on a trade or business in the city. Real estate activity is generally excluded from UBT where the taxpayer holds property solely for its own account, which covers most passive rental ownership, but the exclusion has limits and does not extend to dealer activity or to entities providing services.

City corporate taxes apply to corporations. The classification of the ownership entity therefore has consequences beyond the state level for New York City property.

Passive Loss Rules Follow Federal

New York generally starts from federal adjusted gross income and applies modifications, which means the federal passive activity determination under IRC Sec. 469 carries into the state computation.

An investor who qualifies as a real estate professional and generates a non-passive federal loss carries that treatment into New York, subject to the depreciation modification. This is a meaningful advantage over states like New Jersey and Pennsylvania that restrict loss usage structurally.

The New York loss will simply be smaller, because the bonus depreciation was added back.

Nonresident Owners and Property Transfers

New York taxes nonresidents on New York source income, including rental income from New York property, and requires a nonresident return.

New York also imposes real estate transfer taxes at both the state and, for city property, the city level. New York City's real property transfer tax and the state's mansion tax and additional base tax apply to acquisitions and dispositions at rates that make transaction structuring consequential.

Transfers of controlling interests in entities holding New York real property can trigger transfer tax as well, which catches investors who assume an entity-level transfer avoids it.

Worked Example: Brooklyn Multifamily

An investor acquires a Brooklyn multifamily property for $4,200,000. Land is allocated at $1,100,000, leaving $3,100,000 depreciable. A study reclassifies 22%, identifying $409,200 of five-year property and $272,800 of 15-year land improvements.

Federally, the full $682,000 is bonus eligible in year one, plus $87,927 of structural depreciation, for approximately $769,927.

For New York, bonus is added back. Five-year property produces roughly $81,840 in year one under MACRS, 15-year property roughly $13,640, and structure $87,927, for approximately $183,407.

The first-year difference is $586,520. At a combined New York State and New York City marginal rate near 14.8%, that is roughly $86,800 of state and city benefit deferred rather than lost, recovered across the following fourteen years.

Against a straight-line-only alternative, the study still accelerates roughly $95,480 of state depreciation into year one, worth about $14,100 in the first year alone, with the advantage compounding annually.

State conformity provisions are amended frequently and the mechanics below should be confirmed against the current year instructions before filing.

Planning Points

Track New York and federal basis separately from acquisition. The divergence begins immediately and is expensive to reconstruct at disposition.

For New York City property, confirm the entity classification against the unincorporated business tax rules before acquisition rather than after.

Model transfer tax on both acquisition and the anticipated exit, including the controlling interest rules, since the combined transfer tax burden on New York City property is high enough to affect hold period decisions.

Where the household includes a spouse who can qualify for real estate professional status, the federal treatment carries into New York, which makes the New York position materially better than New Jersey or Pennsylvania.

Frequently Asked Questions

Does New York allow bonus depreciation?

Generally no. New York requires an addback of the federal bonus depreciation deduction under IRC Sec. 168(k) and a recomputation without it, with a narrow historical exception for certain designated zone property.

Is cost segregation worth it in New York?

Yes. Even without bonus depreciation, reclassifying basis from a 27.5-year or 39-year schedule to five and fifteen years accelerates state recovery substantially, and the federal benefit is unaffected.

Do New York rental losses offset wages?

Subject to the depreciation modification, yes, where the federal treatment allows it. New York starts from federal adjusted gross income, so a non-passive federal loss under real estate professional status carries into the state computation. This is more favorable than New Jersey or Pennsylvania.

Does New York City tax rental income separately?

City residents pay city personal income tax on top of state tax. The unincorporated business tax applies to partnerships and sole proprietorships doing business in the city, though holding property solely for one's own account is generally excluded.

Does transferring an LLC interest avoid New York transfer tax?

Often not. Transfers of controlling interests in entities holding New York real property can trigger transfer tax at the state and city level. This catches investors who assume an entity-level transfer is outside the transfer tax rules.
