Search Kings County Property Tax Records

Kings County property tax records cover all of Brooklyn, the most populated borough in New York City. The NYC Department of Finance manages assessments and tax bills for every parcel in Kings County. You can search property records through the ACRIS system for deeds and transfers, or use the Department of Finance portal for assessed values and tax bills. Brooklyn has over 280,000 tax lots, and all of them are in the public record. Whether you own a brownstone in Park Slope or a condo in Williamsburg, these tools give you free access to the data.

Kings County Property Tax Records Through NYC DOF

The NYC Department of Finance is where you find property tax records for Kings County. This is different from upstate counties, which use local Real Property Tax Services offices. In Brooklyn, the DOF handles everything from setting assessed values to sending out tax bills. There is no separate county assessor. The city does it all.

The Department of Finance values every property in Brooklyn each year. The tentative assessment roll lists the value of every parcel in the borough. You can download the full roll as a data file or search for a single property online. The system lets you look up any address in Kings County and see the current assessed value, tax class, and any exemptions on file. Tax class matters in NYC because different property types get taxed at different rates.

Brooklyn properties fall into four tax classes. Class 1 covers one to three family homes. Class 2 is for apartment buildings, co-ops, and condos. Class 3 is for utility company equipment. Class 4 covers commercial and industrial properties. The tax rate for Class 1 in recent years has been around 21%, while Class 4 sits near 10.7%. These rates get set by the City Council each fiscal year.

Search Brooklyn Property Tax Records on ACRIS

The ACRIS system is the main tool for looking up deeds, mortgages, and other recorded documents in Kings County. ACRIS stands for Automated City Register Information System. It covers Brooklyn, Manhattan, Queens, and the Bronx. The system has records going back to 1966. You do not need an account to search. It is free.

To search Kings County records on ACRIS, you can use the property address, the BBL number (Borough-Block-Lot), or the party name. BBL is the parcel identifier used across NYC. Every lot in Brooklyn has a unique BBL that starts with the borough code 3. Once you pull up a parcel, you can see every recorded document tied to that property, including deeds, mortgages, liens, and satisfaction pieces. You can view the actual document images too.

The Kings County office for ACRIS filings is at 210 Joralemon Street, 2nd floor, Brooklyn, NY 11201. All Real Property Transfer Tax returns must be filed through ACRIS. Paper filings are not accepted for Brooklyn. If you need help with ACRIS, the contact center is at (212) 487-6300 or you can email acrishelp@finance.nyc.gov.

Kings County Property Tax Bills and Payments

Property tax bills in Kings County are issued by the NYC Department of Finance. Most Brooklyn property owners get billed quarterly. The city sends out a Notice of Property Value each January, which shows the upcoming assessment. The actual tax bill follows later. You can view your bill online through the DOF property tax bill page by searching with your address or BBL number.

If you disagree with your assessed value, you can challenge it through the NYC Tax Commission. The filing window opens in January and typically runs through March. There is no fee to file. The commission reviews your case and can lower the assessment, but it cannot raise it. This is a separate process from the upstate Board of Assessment Review system.

Brooklyn has some of the highest property values in the state. A brownstone in a neighborhood like Brooklyn Heights or Cobble Hill can carry an assessed value well into the millions. But the assessment system uses ratios, so the taxable value is often much less than the market value for Class 1 homes. That gap between market value and assessed value is one of the more debated parts of the NYC property tax system.

Property Tax Exemptions in Kings County

Kings County property tax records show a wide range of exemptions. STAR is the most common. Basic STAR is for all owner-occupied primary homes. Enhanced STAR is for seniors 65 and over who meet income limits. In NYC, STAR now works as a credit rather than an exemption for new applicants. Existing recipients keep the exemption on their tax bill.

Veterans in Brooklyn can get a partial exemption under state law. The city has adopted the alternative veterans exemption, which gives different levels based on wartime service, combat zone duty, and disability ratings. Senior citizens 65 and older may qualify for an income-based exemption that reduces their assessed value on a sliding scale. Disabled homeowners have their own program too.

Brooklyn also has a large number of properties with nonprofit and religious exemptions. Churches, schools, hospitals, and charitable organizations can get a full or partial exemption from property taxes. The Department of Finance tracks all of these in the assessment roll. You can see which exemptions apply to any parcel when you search the records online.

Brooklyn Property Transfers and Sales Data

Every property sale in Kings County gets recorded through ACRIS. The seller must file a Real Property Transfer Tax return along with the deed. The NYC Real Property Transfer Tax applies to all transfers in the five boroughs. The tax rate depends on the property value and type. For residential properties under $500,000, the rate is 1%. Above that, it goes to 1.425%.

Unlike upstate counties, Kings County does not use the statewide SalesWeb database. Brooklyn sales data is available through ACRIS and the NYC Open Data portal instead. The city publishes rolling sales data that includes sale price, date, property type, and BBL. Researchers and appraisers use this data to find comparable sales for valuation work. It is all free and public.
