Updated September 2026. ICAP is still open to new projects. Preliminary applications are accepted until March 1, 2029, and no benefits attach to construction work performed under a building permit issued after April 1, 2029. The statute also shuts out licensed parking facilities, except one tied to housing-agency-assisted residential construction on a separate tax lot, and consumer storage warehouses, and it designates Governor’s Island a special commercial abatement area beginning January 1, 2026.

ICAP is the New York City property tax abatement for industrial and commercial construction. The acronym is shared with unrelated programs; this one is the Industrial and Commercial Abatement Program, run by the Department of Finance. It is the city’s main as-of-right incentive for building, gutting or expanding a warehouse, an office floor, a hotel or a factory, and the requirement that ends projects outright is a filing date rather than anything on the merits.

What is ICAP, and what does the acronym stand for?

ICAP stands for the Industrial and Commercial Abatement Program. In DOF’s summary, it “offers property tax abatements for up to 25 years for eligible industrial and commercial buildings that are built, modernized, expanded, or otherwise improved.” The authority is Section 489-bbbbbb of the New York State Real Property Tax Law, and DOF decides eligibility and grants the abatement on its own, without the housing-agency partner that 421-a and 485-x require. Small Business Services still has a role, enforcing Executive Order 50 and the M/WBE and labor filings that ride along with the application.

ICAP succeeded the Industrial and Commercial Incentive Program, whose “exemption ended in 2008,” though ICIP benefits approved before then are still valid. The mechanism changed with the name: ICIP granted an exemption, keeping value off the assessment before the tax rate applies, while ICAP grants an abatement, a credit against the tax after it is calculated. Our guide to NYC tax abatements and our explainer on how NYC property tax works both turn on that distinction.

Who qualifies for ICAP, and what does a project have to spend?

Three tests decide it: the use of the finished building, the amount spent, and the location, which has its own section below.

On use, the statute is narrow. “Industrial property” is nonresidential property with “at least seventy-five percent of the total net square footage” used or held out for manufacturing. “Commercial property” is broader, covering “the buying, selling or otherwise providing of goods or services including hotel services,” so hotels are in. Renovation work qualifies only where it does not increase the building’s bulk or its height “by more than thirty percent.”

Several uses knock out the entire tax lot. No abatement is granted “for work on a structure or building where twenty percent or more of the total rentable square footage of such property is or will be dedicated to residential purposes,” although anything under five percent residential is de minimis. Utility property is out except for electricity-generating peaking units, and so are self-storage facilities, consumer storage warehouses and any restricted activity. Licensed parking facilities are out too, unless the garage serves housing-agency-assisted residential construction on a separate tax lot.

Retail does not disqualify a project, it reprices it. On an industrial building, or a commercial building inside a special commercial abatement area, “if retail use exceeds 10% of the tax lot, the excess retail space is granted a 15-year benefit rather than the 25-year benefit.” In the Manhattan renovation areas, retail above five percent of the lot is ineligible outright, except in Lower Manhattan.

The money test is the minimum required expenditure: 30 percent of the property’s taxable assessed value, spent no later than four years from the building permit, and 40 percent for the extra industrial benefit. Two traps hide in that arithmetic. The percentage runs against the assessed value on the roll immediately preceding the permit, not against project cost, and spending on residential or restricted-activity space does not count toward it.

Where in New York City does ICAP apply?

Industrial work is the easy case: eligible industrial construction projects may receive abatements “in any area of the city of New York.”

Commercial work is where the map matters, and the map is mostly Manhattan. New construction reaches “anywhere in the city except for the area south of 96th Street (including the south side 96th Street) and north of Murray, Frankfort, and Dover streets.” Renovation reaches everywhere “except for between 59th Street and 96th Street,” with extra benefits in the Garment District and in Lower Manhattan between Murray Street, Battery Place, South Street and West Street.

The statute calls the excluded band a commercial exclusion area, Manhattan south of the center line of 96th Street, minus the three designated renovation areas and, from January 1, 2026, minus Governor’s Island. One line there costs more deals than the rest of the map: “Any parcel partly located in an excluded area shall be deemed to be entirely located in such area.”

DOF publishes the special commercial abatement area maps by borough on its ICAP page, along with a spreadsheet of the properties inside them, so a lot can be checked before a 25-year schedule is assumed.

What is an ICAP abatement worth?

The abatement is a percentage of a figure called the abatement base, and the base is defined by subtraction: “the amount by which the post-completion tax on a building or structure exceeds one hundred fifteen percent of the initial tax.” The city keeps taxing the property at its pre-construction level plus a 15 percent cushion, and abates a declining share of everything above that.

Three limits cap the value. Apart from the additional industrial abatement, the abatement does not apply to the initial tax or to the land, it “shall not result in any credit or refund of real property taxes,” and it can never exceed the year’s tax. Land tax stays fully payable for the whole benefit period.

The last row is the reward for spending 40 percent instead of 30, and it is unusual, because it reduces the initial tax itself. Industrial work on a peaking unit runs a flat 15 years at 100 percent. Inflation protection is the quiet part of the value. On industrial work, the whole assessment-driven tax increase in years 2 through 13 is added to the abatement base. On commercial work in a special commercial abatement area, only the part of that increase above five percent is added. A physical change that lifts taxable value by more than five percent switches that off for the year, and missing the five-year completion date terminates it outright.

What are the ICAP deadlines, and when does the program close?

The sequence is preliminary application, final application, notice of completion, and the first of those is the one that ends projects. In DOF’s words, “you must submit the ICAP Preliminary Application prior to obtaining a building permit,” and failing to do so “will disqualify you from receiving benefits under this program.”

Fees, for preliminary applications filed on or after April 1, 2017: $150 for the preliminary application, $500 for the final application and $1,000 for the notice of completion.

What keeps an ICAP abatement alive after construction?

An ICAP benefit is not self-sustaining. The recipient must “file biennially with the department, on or before the appropriate taxable status date, a statement of the continuing use of such property,” and DOF may “terminate such benefits upon failure of a recipient to file such statement.” To owners DOF puts it plainly: “you must renew every two years.” That filing is the Certificate of Continuing Use, and a missed one is a common reason a good abatement quietly stops showing on the bill. Our exemption renewals page covers the calendar side of it.

Three obligations run alongside: a biennial business operation data report, an immediate amendment before industrial space drops below 65 percent manufacturing, and income and expense statements. Labor and M/WBE compliance sits with Small Business Services, which requires ICAP applicants and recipients to meet Executive Order 50 and file M/WBE utilization documents. The compliance report goes in with the preliminary application, and DOF’s instructions add SBS filings for projects of $750,000 and over plus a Certificate of Approval above $2.5 million.

Can ICAP be combined with 421-a, 485-x or J-51?

As a rule, no. The statute bars benefits to “a property that is concurrently receiving exemption or abatement of real property taxes under any other law,” and the exceptions are narrow: the not-for-profit and similar exemptions under RPTL 420-a, 420-b and 459-b, exemptions granted only on an owner’s primary residence, and an old ICIP benefit for a separate, earlier project. Nothing in that list reaches 421-a, 485-x, J-51 or the co-op and condo abatement.

In practice they rarely compete, because they aim at different buildings. ICAP grants nothing “for residential construction work,” so a rental or condominium project belongs in 485-x and a residential rehabilitation in J-51. One stacking limit is internal: a second ICAP on the same portion of a property waits four years from the first tax year of the earlier abatement.

Why do ICAP applications fail?

Six patterns account for most of the losses we see, and five of the six cost nothing to avoid.

• The permit came first. A preliminary application filed after the first building permit issues is fatal.
• The final application ran past a year. That is a real deadline but not an automatic death sentence: the statute says benefits are simply not granted until the final application is filed, and DOF may delay them while it investigates the late filing. DOF’s own ICAP page now applies the one-year clock only to preliminary applications filed before March 10, 2017.
• The spend fell short, or the wrong spend was counted toward the 30 percent.
• Residential use crept past 20 percent of rentable square footage and disqualified the lot.
• The lot straddled an exclusion boundary, so the whole parcel was deemed inside it.
• The abatement was won and then lost, because a Certificate of Continuing Use was never filed.

Two further failure modes cost value rather than the grant: retail creeping past 10 percent of an industrial building, and a physical change in years 2 through 13 that lifts taxable value by more than five percent.

Frequently asked questions about ICAP

What does ICAP stand for?

Industrial and Commercial Abatement Program, a New York City property tax abatement run by the Department of Finance under Section 489-bbbbbb of the Real Property Tax Law. It replaced the Industrial and Commercial Incentive Program, whose exemption ended in 2008.

How long does an ICAP abatement last?

Up to 25 years, per DOF. Industrial work and commercial work in a special commercial abatement area run 25 years, ordinary commercial construction 15, Manhattan renovation 12 or 10, and Lower Manhattan new construction 8.

Does Manhattan qualify for ICAP?

Partly. Industrial work qualifies anywhere in the city. Partly. Industrial work qualifies anywhere in the city. Commercial construction in the exclusion area, Manhattan south of the center line of 96th Street, does not. In the three renovation areas only renovation work qualifies, because new commercial construction in a renovation area is barred except in the Lower Manhattan new-construction zone. Governor’s Island qualifies from January 1, 2026.

What is the minimum spend for ICAP?

Thirty percent of the taxable assessed value on the roll immediately preceding the first building permit, spent within four years. Industrial projects reaching 40 percent also earn the additional industrial abatement.

Can ICAP be combined with 421-a or 485-x?

No. A property concurrently receiving another exemption or abatement is barred from ICAP, and the statutory exception list does not include 421-a, 485-x, J-51 or the co-op and condo abatement.

When should the ICAP application be filed?

On or before the day the first building permit is issued, and there is no cure for missing it. With no permit required, a notarized architect or engineer letter goes to DOF within 30 calendar days of the start of construction.
