NYC Co-op/Condo Tax Abatement: File by February 15, 2027

The abatement is a state program, created under Real Property Tax Law § 467-a and administered by the NYC Department of Finance. It applies to tax class 2 co-ops and condos, and the benefit percentage depends on the development's average assessed value per unit, a number DOF calculates, not the board.

The program is large. In fiscal year 2023, according to the NYC Comptroller's audit of the program, 253,686 co-op units received $497.1 million in abatements and 56,437 condo units received $161.9 million. Many Manhattan buildings land in the 17.5% tier, while a good share of Brooklyn co-ops still qualify for more.

The abatement is granted development by development, but eligibility is decided one unit at a time. Under the DOF eligibility rules, a unit qualifies when:

• The development is tax class 2 and does not receive J-51, 421-a, 421-b, 421-g, or 420-c benefits.
• The unit is the owner's primary residence.
• The owner holds no more than three units in the development, one of which is their primary residence.
• The owner purchased on or before January 5 for the tax year beginning the following July 1. A buyer who closes after January 5 waits a year.
• The unit is not owned by a business, such as an LLC, and is not held by the sponsor or the sponsor's successors. DOF allows limited exceptions for LLC and limited partnership ownership tied to security concerns.
• If a trust owns the unit, it must be the primary residence of the trustee, all of the trust's beneficiaries, or the life estate holder.

The LLC rule catches more units than any other. A shareholder who transfers shares into an LLC for estate or liability reasons drops out of the program, and the board is the party that has to notice.

Boards or their authorized managing agents file, not individual owners. DOF is explicit that boards "are responsible for renewing the abatement each year," and the online application in SmartFile is open from October 5 to February 15. Paper applications by mail are still accepted, but online filing is faster and leaves a record.

There are two filing situations:

• First-time developments submit the Cooperative or Condominium Property Tax Abatement Initial Application.
• Developments already receiving the abatement file the annual renewal, which reports units that were added, sold, or no longer qualify.

Either way, the board has to collect proof of primary residency. Per the DOF abatement FAQ, unit owners and shareholders must certify their primary residency to their managing agents or boards, and the board submits that information with the application. Send the certification request with the October budget packet, when owners are already reading board mail, instead of chasing signatures in February.

This is the step that can wipe out the benefit for the entire development. DOF requires a prevailing wage affidavit from developments that have either:

• 30 or more units and an average assessed value above $60,000 per unit, or
• fewer than 30 units and an average assessed value above $100,000 per unit.

The consequence is not partial. In DOF's words: "If your development is required to submit a prevailing wage affidavit and does not, the entire development will lose the abatement for that tax year."

The affidavit certifies that every building service employee is paid the prevailing wage set by the City Comptroller, and § 467-a defines that group broadly: doormen, porters, handymen, janitors, cleaners, and elevator operators, among others, with an exception only for people regularly scheduled under 8 hours per week. For the small Manhattan buildings Ora manages, the $100,000 test is the one to check, because a 12-unit elevator co-op with a full-time super can cross it. The board then has to weigh the abatement against the payroll commitment, and that is a decision to make in October, not on the eve of the deadline.

For a co-op, the abatement lands on the corporation's tax bill, and the statute requires the corporation to credit it "against the amount of such taxes attributable to eligible dwelling units at the time of receipt." In practice that means a per-share credit on the maintenance statements of qualifying shareholders. For a condo, the abatement is applied to the taxes on each eligible unit, so it shows up on the unit owner's own bill.

Many co-op boards pair the pass-through credit with an assessment of similar size, so the cash stays in the building and funds reserves. It is a widely used and legitimate tool, provided the board discloses it plainly and votes it properly. Our guide to reserve fund planning for NYC co-op boards covers how much that account should hold.

The timing matters this year because everything else in the budget is moving the other way. The Rent Guidelines Board's 2026 Price Index of Operating Costs measured building operating costs up 5.3% from April 2025 to March 2026, with insurance up 10.5% and fuel up 11.0%. Those pressures hit co-ops and condos as hard as rentals, as we noted in our RGB Income & Expense Study breakdown.

The co-op/condo abatement is the only line on a NYC board's calendar that cuts a shareholder's tax bill by 17.5% to 28.1% in exchange for a roster and a signature. In the buildings we manage, the risk is never the form. It is the unit that moved into an LLC in August, or the apartment that was sublet all year, that nobody told the board about. Confirm the residency roster in October, not February.

In October 2024 the Comptroller audited DOF's administration of the abatement and found 720 ineligible units receiving the benefit in fiscal year 2023. Among them: 290 units owned by businesses, 27 units where owners broke the primary residence rule, and 123 units in developments that failed to submit a correct prevailing wage affidavit. The audit put the cost of ineligible abatements over fiscal years 2019 to 2024 at $6.5 million, and DOF agreed to remove the units and recover the money.

The practical message for boards is that DOF is now checking ownership and residency against what the board certified. Since the board or its agent signs the filing, the board's own records are the first line of defense:

• Keep every residency certification on file, by unit and by year.
• Log every transfer, estate, and LLC conversion as it happens, and remove the unit from the renewal if it no longer qualifies.
• Confirm the prevailing wage affidavit is filed, and filed correctly, every year it is required.

Transfers are where the data goes stale, and co-op boards now operate under fixed review deadlines for purchase applications. Our guide to the co-op application timeline law covers those deadlines; the same transfer log should feed the abatement renewal.

Here is the part most boards have not heard. Section 467-a authorizes the current abatement schedule "in the fiscal years commencing in calendar years two thousand twelve through two thousand twenty-six." The city fiscal year that began July 1, 2026 is the last one the statute covers, and the application you file by February 15, 2027 is for the year beginning July 1, 2027.

The last extension was Chapter 147 of the Laws of 2023, sponsored by Senator John Liu, which passed both houses on May 31, 2023, was signed June 30, 2023, and added four years. That renewal was signed months after the February 2023 filing deadline, and DOF collected applications on schedule anyway. Expect the same pattern now: file on time, and treat the 2027–28 credit as likely rather than certain until Albany acts.

For budgeting, that means one line of caution. If your board offsets the abatement with an assessment, write the 2027–28 assessment resolution so it is contingent on the abatement being granted, and say so in the budget letter.

October already carries a second board deadline: covered buildings must post their energy efficiency grade by October 31. Put both on the same agenda, and ask whoever manages the building to confirm in writing which filings they own.
