NYC agency · Tax & records
Department of Finance (DOF)
Property tax and assessments, deed and mortgage records (ACRIS), and tax abatements and exemptions.
What DOF handles
The Department of Finance assesses property value, bills property tax, records deeds and mortgages in ACRIS, and administers tax abatements and exemptions — J-51, 421-a, ICAP, the co-op/condo abatement, solar, and more.
What owners deal with
- Annual assessed value and property-tax bills; tax appeals (Tax Commission).
- ACRIS ownership, deed, and mortgage records by BBL.
- Abatement/exemption applications and compliance (some require registration or benchmarking to keep).
- Tax liens and the annual lien sale for unpaid taxes, water, and charges.
How to look it up
Use DOF Property Tax lookup and ACRIS by borough-block-lot. Your building’s BBL, owner of record, and assessed value appear in the NYC Building Compliance compliance profile.
