A Westchester County tax lien sale is not run by the county itself. Each of the 25 cities and towns in Westchester enforces delinquent property taxes on its own under New York’s Real Property Tax Law (RPTL), and any lien sale or auction is a municipal action, not a county one.1Westchester County Department of Finance. Taxes and Liens – Overview If your taxes are behind, you are dealing with Yonkers, White Plains, Mount Vernon, or whichever municipality your property sits in. After a lien is sold, you generally have at least two years to pay what you owe and keep the home. Miss that window and the lien can ripen into foreclosure, though several protections and relief options exist along the way.
Who Sells the Lien and Under What Law
New York authorizes municipalities to sell delinquent tax liens under RPTL 1190. The statute lets a tax district contract to sell some or all of its delinquent liens to the New York Municipal Bond Bank Agency or to tax lien entities the bond bank creates.2New York State Senate. New York Code RPT 1190 – Contracts for the Sale of Delinquent Tax Liens Once sold, the purchasing entity steps into the municipality’s shoes. It holds the lien, collects the debt, and can eventually pursue foreclosure if you do not pay.
Interest keeps running the whole time. RPTL 924-a sets the rate on delinquent property taxes in New York at one percent per month, or 12% per year.3New York State Department of Taxation and Finance. Interest Rates on Late Payment of Property Taxes RPTL 1190 carries that rate (or a higher local rate if applicable) over to liens that are sold, and it accrues on the full amount owed, including penalties and charges, from the sale forward.2New York State Senate. New York Code RPT 1190 – Contracts for the Sale of Delinquent Tax Liens
The Notice You Should Receive
New York requires multiple rounds of notice before you can lose rights to your home. What you get depends on whether the municipality is selling a lien under RPTL 1190 or pursuing foreclosure under Article 11.
Before a Lien Sale
For a sale under RPTL 1190, the enforcing officer must mail notice to every affected owner at least 30 days before the scheduled sale date. Notice goes to the owner listed on the tax roll, or to a new owner if the property has changed hands since the last taxable status date, and to anyone who has filed a declaration of interest in the property.2New York State Senate. New York Code RPT 1190 – Contracts for the Sale of Delinquent Tax Liens
Before Foreclosure
If the lien reaches the foreclosure stage, the requirements tighten. Under RPTL 1124, the enforcing officer must publish a foreclosure notice in at least two newspapers of general circulation in the tax district, running the notice in three non-consecutive weeks within a two-month period.4New York State Senate. New York Real Property Tax Law 1124 – Public Notice of Foreclosure
RPTL 1125 then requires personal notice to every party with an interest in the property, sent by both certified mail and ordinary first-class mail. Notice is considered received unless both mailings come back from the postal service within 45 days.5New York State Senate. New York Code RPT 1125 – Personal Notice of Commencement of Foreclosure Proceeding Courts take these steps seriously. When notice is skipped or inadequate, the entire foreclosure can be thrown out as constitutionally defective.
How Long You Have to Redeem
A lien does not strip you of ownership. RPTL 1110 gives owners two years from the lien date to redeem by paying off the debt and clearing the lien.6New York State Senate. New York Code RPT 1110 – Redemption, Generally
That two-year window is the baseline. Under RPTL 1111, a municipality can pass a local law extending the redemption period to three or four years for residential or farm property.7New York State Senate. New York Real Property Tax Law 1111 – Extended Redemption Period The window shortens to one year for vacant and abandoned properties placed on a vacant-and-abandoned roll before the taxes became delinquent.6New York State Senate. New York Code RPT 1110 – Redemption, Generally
To redeem, you pay the full amount of delinquent taxes plus all accrued interest at the 12% annual rate, penalties, and any charges added after the lien sale. Once you pay in full, the lienholder must release the claim and your ownership rights are restored without restriction.
What Happens If the Redemption Period Runs Out
If the redemption period passes without payment, the lienholder or the municipality can begin foreclosure. In New York this is an in rem proceeding, meaning the legal action is directed at the property itself rather than against you personally. The process is governed by RPTL 1130 through 1136 and runs through the courts, which must verify that every required step was followed before granting a foreclosure judgment.8New York State Senate. New York Code RPT 1136 – Final Judgment
The most dangerous deadline in the entire process sits inside RPTL 1131. If you fail to redeem or file an answer in the foreclosure proceeding, you are permanently barred from any right, title, or interest in the property, and a default judgment is entered against you. You then have only one month after the judgment is entered to file a motion to reopen the default.9New York State Senate. New York Real Property Tax Law 1131 – Default Judgment Miss that one month, and your ownership is gone.
Ways to Resolve the Delinquency Before You Lose the Property
The earlier you act, the more of these options remain open.
Installment Payment Agreements
Under RPTL 1184, municipalities can enact local laws allowing owners to pay off delinquent taxes in installments rather than a lump sum. Agreements can last up to 36 months, on a monthly, quarterly, or semi-annual schedule. The municipality can require a down payment, but it cannot exceed 25% of the delinquent amount.10New York State Senate. New York Real Property Tax Law 1184 – Payment of Delinquent Taxes in Installments
Not everyone qualifies. You are ineligible if you have a delinquent lien on another property in the same tax district that is not part of the agreement, if a property you owned was foreclosed within the past three years, or if you defaulted on a previous installment agreement within the past three years.10New York State Senate. New York Real Property Tax Law 1184 – Payment of Delinquent Taxes in Installments Contact your local tax enforcement office early to find out whether your municipality has adopted the option.
Senior Citizen and Disability Exemptions
If you are 65 or older, you may qualify for a property tax exemption under RPTL 467. The exemption uses a sliding scale based on income: municipalities set a maximum income threshold (the statute allows a range from $3,000 to $50,000), and the exemption percentage decreases as your income rises above that threshold.11New York State Senate. New York Real Property Tax Law 467 – Exemption for Senior Citizens In parts of Westchester County, the income ceiling has been set as high as $58,400. If you are married or co-own with a sibling, only one person needs to be 65, and you must own and occupy the property as your primary residence for at least 12 consecutive months.
An exemption will not erase existing delinquencies, but it can lower future bills enough to keep you from falling further behind. Apply through your municipal assessor’s office well before the filing deadline.
New York Homeowner Assistance Fund
The New York State Homeowner Assistance Fund (HAF), funded by the U.S. Treasury, covers delinquent property taxes, water and sewer bills, mortgage payments, and other housing costs for homeowners facing financial hardship linked to the COVID-19 pandemic.12U.S. Department of the Treasury. Homeowner Assistance Fund You must own and occupy the property as your primary residence. Funding is limited and may not remain available indefinitely, so check with your municipality or the state program portal for current status.
Chapter 13 Bankruptcy
Filing Chapter 13 triggers an automatic stay that immediately halts most collection activity, including tax lien foreclosure. In Chapter 13 you propose a repayment plan lasting three to five years, during which creditors cannot start or continue collection efforts.13United States Courts. Chapter 13 Bankruptcy Basics The stay is not permanent. If the plan fails or the court lifts the stay, the foreclosure picks up where it left off. Treat this as a last resort after exhausting other options.
Challenging the Lien
If the underlying assessment was wrong, or the municipality failed to follow proper notice procedures, you can challenge the lien’s validity. Procedural failures, especially inadequate notice, are the most common basis for successful challenges, and courts have repeatedly invalidated foreclosures where the required mailings or publications were deficient. An attorney experienced in New York real property tax law can evaluate whether the process had any gaps worth pursuing.
If You Lose the Property, You May Be Owed the Surplus
For years, when a municipality foreclosed and sold a property for more than the tax debt, many jurisdictions kept the difference. That practice ended in 2023, when the U.S. Supreme Court unanimously ruled in Tyler v. Hennepin County that retaining surplus proceeds from a tax foreclosure sale violates the Fifth Amendment’s Takings Clause. Chief Justice Roberts wrote that the government “cannot take more from an owner than what is due.”14Supreme Court of the United States. Tyler v. Hennepin County, Minnesota (2023)
New York amended Article 11 in 2024 in response. The enforcing officer must now determine whether a surplus exists within 45 days of selling a foreclosed property. If there is a surplus, former owners have the right to file a claim before the court confirms the sale report. For residential property, the law goes further: if no former homeowner has filed a claim by the time the sale is confirmed, the proceeding stays open for at least three additional years to hear a late claim. Any surplus that goes completely unclaimed eventually goes to the tax district to reduce its tax levy, not to the state comptroller.
If you lose a Westchester property to tax foreclosure and it sells for more than what you owed, file a surplus claim as soon as you can. The three-year residential extension is a backstop, not a reason to wait.
Credit and Federal Tax Aftermath
Since 2017, the three major credit bureaus have stopped including tax liens on consumer credit reports, so a tax lien alone will not show up as a derogatory mark or directly damage your score. The situation is not harmless, though. If the lien progresses to foreclosure, the loss of the property brings mortgage default, judgment records, and financial disruption that lenders do notice. And selling or refinancing a property with an outstanding lien is essentially impossible, because the lien must be satisfied before clean title can transfer. The practical effect is that the property becomes illiquid until the debt is paid.
Losing property through tax foreclosure can also create federal income tax exposure that catches many former owners off guard. The IRS treats a foreclosure as a sale, so you may need to report a capital gain or loss depending on the property’s value at the time of foreclosure compared to your original cost basis. The rules differ for rental property and a primary residence. If any portion of the tax debt is forgiven or canceled, the canceled amount generally counts as taxable income, with exceptions for insolvency and bankruptcy, among others. Speak with a tax professional before your next filing deadline if a foreclosure has occurred.
