NYC Co-op and Condo Property-Tax Abatement: What Owners Should Check

New York City's co-op and condo property-tax abatement can reduce the tax attributable to an eligible unit, but an individual owner usually does not submit the building application. The board or managing agent files for the development and reports which units qualify.

Reviewed August 4, 2026. Eligibility, percentages, and filing rules can change. Confirm the current record with the managing agent and NYC Department of Finance.

The basic eligibility pattern

The unit must generally be in an eligible Tax Class 2 co-op or condo and used as the owner's primary residence. Sponsor units, units owned by many business entities, and investor or second-home units generally do not qualify. Ownership of multiple units and trust arrangements require a closer reading of the rules.

The published abatement percentage depends on the development's average assessed value per unit. Current tiers range from 17.5% to 28.1%. That percentage applies to the eligible property tax, not to the unit's market price or common charges.

The building files, but the owner supplies the facts

The board or managing agent collects unit-owner names and primary-residence certifications, then files with the Department of Finance. The normal filing deadline is February 15. A buyer who closes after the building has assembled its roster can be missed unless ownership and residency records are updated promptly.

After closing, send the managing agent:

• the recorded or closing ownership information it requests;
• the names of all owners;
• the correct mailing address;
• the primary-residence certification; and
• any trust or estate documents needed to establish beneficial ownership.

Ask when the next building filing occurs and request written confirmation that the unit was included.

How to verify the benefit

For a condo, review the unit's Department of Finance account and tax bill. For a co-op, taxes are assessed at the building level and the economic benefit may flow through the corporation's maintenance calculation, so request the board or managing agent's allocation statement. Do not rely only on the seller's prior maintenance bill; a seller's eligibility does not automatically prove the buyer's.

Common reasons the benefit disappears

• The unit is no longer the owner's primary residence.
• Ownership changed but the managing agent was not notified before filing.
• The unit moved into an LLC or other ineligible ownership form.
• The building's filing omitted or misclassified the unit.
• The owner confused this city abatement with the separate state STAR credit.

Correcting an omission can take time and may depend on the filing cycle. Raise it as soon as the discrepancy appears.
