Search for "Westchester County tax foreclosure" and you will find plenty of pages describing a county that sends notices, runs auctions and takes houses. That is not how it works here. In Westchester, the county government is mostly in the background. The real enforcement happens at the level of your city or town, and the rules can differ from one municipality to the next. This guide explains who actually holds the power over an unpaid tax bill in Westchester, how the in rem process works when a municipality uses it, and how to protect the equity in your house while there is still time.
It is general information. For your parcel, the receiver of taxes in your city or town, or a real estate attorney, can give you exact figures and dates.
In Westchester, your city or town tax office, not the county, collects the property tax bill (including the county's share) and pursues unpaid balances. The county itself does not hold tax lien sales. So the first call when you fall behind is to the receiver of taxes or city finance office named on your bill.
Why Westchester Works Differently
Westchester has 6 cities (Mount Vernon, New Rochelle, Peekskill, Rye, White Plains and Yonkers) and 19 towns. According to the county Department of Finance, those 25 municipalities assess property, bill and collect taxes, collect the county portion as part of that bill, and guarantee the full county amount to the county government. They also keep the late-payment interest and penalties and pursue the property owners who do not pay.
Several other layers sit on top of that:
- Town and county taxes: billed by the town or city receiver, usually in the spring in the towns.
- School taxes: often billed separately and on a different schedule, commonly in the fall with a second installment later.
- Village taxes: if you live in an incorporated village such as Ossining, Tarrytown, Mamaroneck or Pelham, the village bills its own tax as well.
- Interest and penalties: set by state law and the Westchester County Tax Law and kept by the collecting municipality. Ask for a payoff figure good through a specific date, because the balance changes each month.
That structure explains why two neighbors on opposite sides of a town line can face different enforcement processes for the same missed payment.
Lien Sales and Who Holds Your Lien
Unpaid taxes become a lien on the property. In Westchester, some cities and towns sell those liens, at an auction or in a bulk sale, to investors who pay the tax amount and then collect it from the owner with interest. The county's own finance department notes that it does not hold these sales but that municipalities occasionally do.
- Your lien may no longer belong to the town. If it was sold, the payoff may need to go through the lien holder or its servicer, and the amount will include the interest and charges they are allowed to collect.
- A lien holder can foreclose. Westchester's tax law allows the holder of an unredeemed tax lien to bring a foreclosure action in court. That is a lawsuit, with service of papers and a court schedule, and it should be answered.
- You still own the house. A lien, sold or not, does not transfer title by itself. It gives someone the right to foreclose if it stays unpaid.
- Check the record. A title search or a call to the receiver will tell you whether your lien was sold and to whom.
The In Rem Proceeding, Step by Step
"In rem" means the case is brought against the property itself rather than against you personally. New York's Real Property Tax Law Article 11 sets out the statewide model, and cities can follow their own charter provisions. The City of Yonkers is a useful example because its code spells the process out:
- Only older liens. Yonkers' in rem process applies to liens at least two years old.
- Public notice. The city publishes a notice of foreclosure listing the parcels, and owners of record and others with an interest are notified.
- A redemption deadline. Before publication, the Commissioner of Finance sets a redemption deadline at least eight weeks after the first publication. Paying everything owed by that date takes your parcel out of the case.
- Answering. If you have a legal objection, such as a defect in notice or a payment that was not credited, you can file an answer in the proceeding instead of letting it pass by default.
- Judgment. For parcels that are not redeemed or successfully defended, the court enters a judgment and the city takes title. After that, the right to redeem is gone.
Other Westchester municipalities may use lien sales, in rem proceedings or both, under their own procedures. The common thread is that each process has a last date to pay, and missing it is what turns a tax debt into the loss of the house.
After the U.S. Supreme Court ruled in Tyler v. Hennepin County (2023) that a government cannot keep more than the tax debt when it takes and sells a home, New York amended RPTL Article 11 in 2024 (Laws of 2024, chapter 55, Part BB) to create a way for former owners to claim surplus after a tax-foreclosed property is sold. That right is real, but it applies after you have lost the house, auction prices are often far below what a normal sale brings, and claims have deadlines and procedures. It is much better to capture your equity yourself, before the redemption date.
A Sample Timeline
Every municipality's calendar is different. This is a simplified example of how an in rem case like the one in Yonkers' code can unfold, not a schedule for your property.
| When | What happens | Your move |
|---|---|---|
| Bill due date | Tax goes unpaid and becomes a lien; interest begins | Pay, or ask the receiver about options right away |
| Months after | Interest and penalties grow; the lien may be sold in some municipalities | Find out who holds the lien and get a written payoff |
| Lien reaches two years | Parcel becomes eligible for in rem foreclosure | Pay, sign an agreement if offered, or plan a sale |
| Notice published | Foreclosure notice lists the parcel and sets the redemption deadline | Calendar the deadline; consult an attorney |
| At least 8 weeks later | Redemption deadline | Pay in full or close a sale before this date |
| After the deadline | Judgment; the city or town takes title | Only a possible surplus claim remains |
Getting Current and Lowering the Bill
- Ask about an installment agreement. State law lets many tax offices accept payments over time on delinquent taxes, and some Westchester municipalities do. Ask the receiver what is available for your parcel and whether staying current on it keeps the property out of the next enforcement round.
- Make sure STAR is applied. Basic STAR lowers school taxes on a primary residence, paid as a state credit for households with income up to $500,000, or as an exemption for some long-time owners. Enhanced STAR gives more to income-qualified owners 65 and older. Check at tax.ny.gov.
- Look at local exemptions. Many towns, cities and school districts offer reductions for income-qualified seniors, people with disabilities and veterans. Applications go to your assessor.
- Grieve the assessment. If the house is over-assessed, file a grievance on your municipality's Grievance Day. See our post on what to do when Westchester property taxes are too high.
- Chapter 13. A bankruptcy filing stops collection and can spread tax arrears over a three-to-five-year plan. Speak with a bankruptcy attorney first.
Note that New York's pandemic-era Homeowner Assistance Fund, which once helped with tax arrears, has closed and is no longer taking applications.
When Selling Is the Better Exit
If you cannot catch up, and the house is worth meaningfully more than what you owe, selling before the redemption deadline protects that difference. A simple illustration, not a prediction of any price: a house worth $650,000 in good condition, needing about $70,000 of work, with $40,000 in tax arrears and a $300,000 mortgage. If it sold as-is for $540,000, the taxes and mortgage would be paid at closing and about $200,000 would remain before any other liens. Lose the same house to a judgment, and the outcome depends on what an auction brings and whether a surplus claim succeeds.
You do not need to pay the taxes before selling. The title company gets the exact payoff from the receiver, or from the lien holder if the lien was sold, and pays it at the closing table. If the property is already on an enforcement list, New York's Home Equity Theft Prevention Act may also give you specific contract protections and a five-business-day right to cancel a sale to an investor. If your bill comes from the City of White Plains, we buy houses in White Plains as-is and close around that payoff.
