City of Buffalo tax sale, 2026 season

Verified

Buffalo sells its own delinquent property, separately from Erie County. The city's In Rem Foreclosure page states that the departments of Assessment and Taxation and Law are responsible for collecting delinquent accounts through the In Rem foreclosure auction, and that properties with arrears in property taxes, user fees, sewer rent and other judgments are auctioned off in an open and fair public auction. Erie County's own sale covers county liens and leaves city parcels to this process.

The status is the story: no Buffalo in rem auction has been held since the three day sale of Tuesday, October 29 through Thursday, October 31, 2019 at the Buffalo-Niagara Convention Center. A City Charter Revision Commission agenda of December 17, 2025, posted on the city's site, notes there has not been an in rem auction since 2019 and that thousands of properties would be at risk in 2026 assuming an auction is held. None is announced in the city sources read, and no money terms for a future city auction are published, so this page states the mechanism and the gap rather than borrowing Erie County's terms, which belong to a different sale.

Research City of Buffalo parcels before you bid

A sale list gives you the parcels, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across City of Buffalo, searchable by address, owner, or county, including parcels that never reach a sale list.

How New York tax foreclosure works

Unpaid taxes become a lien on the property, and the city enforces that lien in court under Real Property Tax Law Article 11, the in rem foreclosure process.
The owner gets a redemption period, two years from the lien date by default, longer where a local law extends it for homes or farms. Paying everything owed during that window ends the case.
When the period expires, the court can award the property to the city. The former owner's right to redeem is over at that point; there is no post-sale redemption period on a New York tax deed.
The city then sells at public auction, which is the sale this page tracks. Deeds are usually quitclaim, bids can require governing body approval, and any surplus over the taxes and charges is handled under RPTL sections 1195 to 1197 for the former owner and lienholders.

How registration works

Not published, because no sale is scheduled. The city published no registration procedure, bidder requirements or deadlines for a future auction in the sources read. When a sale is announced, its notice carries the registration terms; nothing on this page should be read as the county's registration rules, which govern a different auction.

Terms: what a bid actually costs

The city's pages publish the mechanism and no money terms for any current sale, because there is no current sale. The rows below say so individually rather than importing figures from the Erie County auction, whose deposit and deed rules are the county's own:

Deposit or down payment	Not published in the sources read.
Buyer premium	Not published in the sources read.
Balance due	Not published in the sources read.
Deed type	Not published in the sources read.

Before you bid

Owners facing foreclosure may contact the Department of Assessment and Taxation at (716) 851-5733 (extension 2) to discuss payment plans and other options, per the city's In Rem Foreclosure page. Buyers have nothing to prepare against a date: the working habit for Buffalo is a watch on the city's site for an announced auction, because a resumed sale after a seven year pause would arrive with its own new terms, and the 2019 terms are not published in the sources read either.
