Updated October 2026. NYC billing rules, STAR limits and grievance dates checked with the city and state this month.
To look up NYC property taxes, search the address or BBL (borough-block-lot) number in the Department of Finance’s Property Tax Public Access portal. It shows your bills and notices of value. Homes assessed at $250,000 or less are billed four times a year. Outside the city, search your county or town assessor’s site with the SBL (section-block-lot) number.

- NYC uses a BBL number. Find it by address in the Department of Finance portal or in ACRIS.

- To grieve, most towns hear complaints on the fourth Tuesday in May. NYC’s deadline is March 15 for Class 1 homes and March 1 for other property.
How do I look up property taxes in NYC?
Use the city’s own tools. They’re free and they’re the official record.
- Go to the NYC Department of Finance Property Tax Public Access portal.
- Search by address, or by borough, block and lot.
- Open the property to see current and past bills, the notice of property value and other statements.
Don’t know the BBL? Search the address in ACRIS document search. ACRIS covers Manhattan, Queens, the Bronx and Brooklyn back to 1966, and it shows the BBL with every deed and mortgage. For Staten Island deeds, check the Richmond County Clerk.
What is a BBL number?
A BBL is NYC’s parcel ID. It has three parts: a borough code, a block number and a lot number. Borough codes are 1 for Manhattan, 2 for the Bronx, 3 for Brooklyn, 4 for Queens and 5 for Staten Island. You’ll see it on your tax bill, your deed and the city’s digital tax map.
Condos are a special case. Each unit has its own lot number, plus a “billing” lot for the whole building. Use the unit’s lot to find your own bill.
Can anyone look up NYC property taxes?
Yes. Property tax bills, values and recorded deeds are public records in New York. You can look up any address, not just your own. That’s handy before you make an offer on a home or a condo.
How do I find property taxes outside NYC?
Outside the city, each town or city assesses property, and the county keeps the tax maps. Your parcel ID is usually called the SBL, for section, block and lot. It may also be called the tax map number or print key. You’ll find it on your tax bill and your deed.
Start with your county’s real property office. Here are the main portals, checked on October 21, 2026.
| County | Where to search |
|---|---|
| Albany | albanycountyny.gov, then Real Property |
| Dutchess | dutchessny.gov — RPTS |
| Erie (Buffalo) | Erie County Real Property Tax Services |
| Monroe (Rochester) | monroecounty.gov, then property tax records |
| Nassau | nassaucountyny.gov, then Department of Assessment |
| Orange | co.orange.ny.us — Real Property |
| Saratoga | saratogacountyny.gov — Real Property Tax |
| Suffolk | suffolkcountyny.gov — Assessment |
| Westchester | westchestercountyny.gov, then tax search |
| Onondaga, Ulster | Search “real property tax services” on the county’s official site |
Not sure who assesses your home? The state’s NY Tax Dept — Real Property pages list assessors and links to the Municipal Data Portal.
How are New York property tax bills set up?
In NYC, the Department of Finance mails bills about a month before they’re due. If a bank or mortgage company pays your taxes, the bill goes to them, not you.
| NYC assessed value | How often you’re billed | Due dates |
|---|---|---|
| $250,000 or less | Quarterly | July 1, October 1, January 1, April 1 |
| More than $250,000 | Twice a year | July 1, January 1 |
Outside NYC, you usually get separate bills: a town and county bill, and a school tax bill. Dates vary by town and school district.
How does the STAR credit work?
STAR lowers school taxes on your main home. New owners get it as a check or direct deposit, called the STAR credit. Basic STAR has no age limit. The income cap is $500,000 for the credit, or $250,000 for the older exemption. Enhanced STAR adds more for owners 65 and older with lower incomes.
Register once with the state, as soon as the home is your main residence. The NY Tax Dept — STAR page has the form. Have your purchase date and the seller’s names handy.
How do I grieve my assessment in New York?
“Grieving” means asking for a lower assessment. It’s free, and you don’t need a lawyer.

What should New York sellers and buyers check?
Before you list or buy, pull the tax bill and the latest assessment. Buyers will ask what the taxes run, and lenders will too. Check whether the STAR benefit is a credit or an exemption, since it doesn’t carry over to a new owner.
