The tax benefits of owning commercial real estate come from five main sources: depreciation deductions that shelter rental income, mortgage interest deductions, 1031 exchanges that defer capital gains indefinitely, pass-through deductions on qualified business income, and, in New York City, property-level abatement programs like 467-m and ICAP that reduce the tax bill itself. Together they make commercial real estate one of the most tax-efficient ways to hold wealth in the United States. A building can throw off real positive cash flow while reporting little or no taxable income for years. Below are the mechanics and limits of each benefit, the NYC-specific layers, and the points where any serious owner should bring in a CPA before acting.
Depreciation: the foundation of commercial real estate tax shelter
Nonresidential commercial property depreciates over 39 years on a straight-line basis (residential rental property, including NYC multifamily, uses 27.5 years). Land is not depreciable, so the split between land and improvements in your purchase price allocation matters. In Manhattan, where land is a large share of total value, that allocation deserves real attention at acquisition.
In practice the effect is large. Buy a commercial building at $13M with $10M allocated to improvements and you deduct roughly $256,000 a year against the property's income: cash you keep, on income the IRS does not tax today. Buildings with strong cash-on-cash returns can report close to zero taxable income for years. The cost is depreciation recapture. When you sell, accumulated depreciation is recaptured at up to 25%, which is exactly why the 1031 exchange is the companion strategy.
Cost segregation and bonus depreciation: front-loading the benefit
A cost segregation study, performed by an engineering-based specialist for typically $5,000–$20,000, breaks a building into components the tax code lets you depreciate faster: 5-year property (carpeting, certain fixtures and equipment), 7-year property, and 15-year land improvements. On a typical commercial asset, 20–35% of the depreciable basis can be moved out of the 39-year bucket.
Bonus depreciation turns that reclassification into a first-year event. Under the rules restored in 2025, qualifying short-life property can be written off entirely in year one. On a $10M acquisition where a study reclassifies $2.5M into short-life categories, that can mean a seven-figure first-year deduction. The rules have changed several times this decade and interact with the rest of your tax position, so this is the one area where running the numbers with your CPA before closing, rather than after, clearly pays for itself.
The 1031 exchange: deferring gains indefinitely
Section 1031 lets you sell investment real estate and roll the full proceeds into like-kind replacement property without recognizing capital gain or depreciation recapture. You have 45 days to identify replacements and 180 days to close, with a qualified intermediary holding the funds throughout. Investors chain exchanges for decades, trading up from a small mixed-use building to institutional assets without ever paying tax on the appreciation along the way.
The endgame is the step-up in basis. When an owner dies holding exchanged property, heirs generally receive the asset at fair market value, and the deferred gain is never taxed. 'Swap till you drop' is a cliché in this business because it really does work as a wealth-transfer strategy. Model your own numbers with Skyline Properties' 1031 exchange calculator. Exchange timelines are also one of the most common reasons NYC sellers run confidential off-market processes: a quiet sale with a controlled closing date protects a 180-day clock in a way a public marketing campaign can't.
Interest deductions and the pass-through benefit
Mortgage interest on commercial acquisition and improvement debt is deductible against property income. Larger owners run into the business-interest limitation rules, but an electing real property trade or business can generally opt out in exchange for slightly slower depreciation on the building. Most NYC ownership structures make that election as a matter of course.
Most private commercial real estate is held in LLCs and partnerships taxed as pass-throughs, and qualified business income from rental real estate can qualify for the 20% pass-through deduction, subject to income thresholds and the wage-and-basis tests. Entity structure, state and city tax treatment (NYC's unincorporated business tax reaches some structures), and the pass-through deduction all affect one another. Set up the entity with your CPA and real estate attorney before you sign a contract, because restructuring after closing is expensive.
NYC-specific programs: 467-m, ICAP, and the abatement layer
New York City adds property-tax programs on top of the federal benefits. The headline program in 2026 is RPTL §467-m: up to a 35-year property-tax exemption for qualifying office-to-residential conversions in Manhattan south of 96th Street, with at least 25% of units permanently affordable. On a large conversion the abatement's net present value can run into nine figures, and it is often the line item that makes the conversion math work. Skyline Properties brokered the $135M sale of 6 East 43rd Street, a 441-unit Vanbarton Group conversion with 111 affordable units, where 467-m underwriting was central to the deal. Model any candidate building with the 467-m calculator.
ICAP (the Industrial and Commercial Abatement Program) abates part of the tax increase created by qualifying construction or renovation of commercial and industrial buildings, mostly outside the Manhattan core, for up to 25 years. For owners repositioning older assets, ICAP eligibility belongs in the underwriting next to the construction budget. For the wider NYC tax picture, read our NYC property tax guide for investors.
What the tax benefits do not do
Tax benefits make a good deal better. They won’t rescue a bad one. Depreciation shelters income the building actually produces, and an overpriced acquisition with weak NOI has little income to shelter. Recapture makes depreciation a deferral rather than an exemption, unless you exchange or hold until death. Passive-loss rules limit how much paper loss a passive investor can use against other income in a given year (real estate professional status changes this for owners who qualify). And every figure in this article describes general market practice and is not advice for your return. The owners who capture these benefits in full bring their CPA into the acquisition underwriting, and not only into the April filing.
How Skyline Properties approaches tax-driven ownership decisions
Many of Skyline Properties' off-market investment sales mandates start with a tax event: an owner facing a 1031 deadline, a family weighing step-up planning against a sale today, a conversion candidate with a limited 467-m window, an estate that needs a firm valuation without public exposure. Robert Khodadadian, Founder, President & CEO, has closed more than $976M in NYC commercial transactions, including the $65M 99-year ground lease at 236 Fifth Avenue, a structure family offices often choose for its long-duration, tax-efficient income. If a tax question is driving your hold-or-sell decision, start with a confidential broker opinion of value: no cost, no public footprint, and a defensible number your CPA and attorney can plan around.
Frequently asked questions
- How much depreciation can I take on a commercial building?
- Nonresidential commercial buildings depreciate over 39 years straight-line on the improvement value (not land). A building with $10M of depreciable basis produces roughly $256,000 of annual deductions. A cost segregation study can reclassify 20–35% of that basis into 5-, 7-, and 15-year property, and the bonus depreciation rules restored in 2025 can make much of the reclassified amount deductible in year one. Confirm the current rules with your CPA; they have changed repeatedly this decade.
- Do I pay taxes when I sell a commercial property?
- A straight sale triggers capital gains tax on the appreciation plus depreciation recapture at up to 25% on the depreciation you took. A properly executed 1031 exchange defers both by rolling the proceeds into like-kind replacement property within 180 days. Heirs who inherit exchanged property generally receive a stepped-up basis, which can eliminate the deferred gain permanently. New York State and City transfer taxes still apply at closing regardless of federal deferral.
- What is the 467-m tax abatement worth?
- RPTL §467-m grants up to a 35-year property-tax exemption for qualifying office-to-residential conversions in Manhattan south of 96th Street, with 25% of units permanently affordable. The full 35 years applies to construction commenced by June 30, 2026, stepping down to 25 years by the June 30, 2031 final deadline. On a large conversion the net present value can reach nine figures. The largest Skyline Properties-brokered 467-m transaction is 6 East 43rd Street: $135M, Vanbarton Group, 441 units. Use the 467-m calculator to model a specific building.
- Are commercial real estate tax benefits available to small investors?
- Yes. Depreciation, mortgage interest deductions, and 1031 exchanges apply to a $2M mixed-use building the same way they apply to a $200M tower. The main limit for smaller passive investors is the passive-activity loss rules, which can defer the use of paper losses against unrelated income. Real estate professional status, direct active ownership, and entity structure all affect the outcome, so have the CPA conversation before your first acquisition, not after.
