How Long Can Property Taxes Go Unpaid in New York State?

In most of New York State, property taxes can go unpaid for about two years before the local government can foreclose and take the property permanently. That two-year redemption period is the default under Article 11 of the Real Property Tax Law, counted from the lien date.¹ New York City works on a different system: tax liens on owner-occupied one- to three-family homes and residential condos cannot be sold to a private investor until the debt has been unpaid for at least three years and totals $5,000 or more.² Interest and penalties start the day after the bill is due, so the total you owe grows every month you wait.

The Two-Year Default Statewide

Article 11 sets the standard clock. Two years from the lien date, the tax district can begin foreclosure. During those two years, you can still redeem the property by paying the delinquent taxes plus all interest and penalties that have accrued.

Local governments have some room to adjust the window. A tax district can extend the redemption period for residential or farm property. It can also shorten the period to just one year for property that has been officially listed as vacant and abandoned.¹ If your home is occupied and you’re paying attention, you get the full two years. If a property is boarded up and on the abandoned list, expect half that.

How New York City Is Different

New York City doesn’t foreclose directly for unpaid taxes. Instead, the city sells the tax lien to a private investor at its annual lien sale, and that investor can eventually foreclose if you still don’t pay. The eligibility rules depend on the property:

Owner-occupied one- to three-family homes: lien can be sold once tax debt has been unpaid at least three years and totals at least $5,000.
Residential condominiums: same three-year, $5,000 threshold.
All other properties, including commercial, mixed-use, and larger residential buildings: lien can be sold after just one year of delinquency, with a $1,000 minimum.

A homeowner in a small residential property has a meaningful buffer. A commercial owner does not.² Once a private investor holds the lien, that investor collects the debt plus fees and can move to foreclose if payment doesn’t come.

What You Owe While the Clock Runs

The two- or three-year runway is not free time. Interest starts accruing the day after the due date, and it compounds each month the balance sits.

Outside New York City, the interest rate on delinquent property taxes is set each year by the Commissioner of Taxation and Finance and cannot fall below 12% per year. Interest is calculated monthly at one-twelfth of the annual rate for each month or partial month the taxes remain unpaid.³ On a $5,000 bill at 12%, that’s at least $50 in interest every month, before any local penalty is layered on top.

New York City sets its own rates. For July 1, 2025 through June 30, 2026, the annual rates on late property taxes are:

6% for properties with assessed values of $250,000 or less
9% for assessed values above $250,000 but at or below $450,000
16% for assessed values above $450,000

These are considerably lower than the rates the city has charged in prior years.⁴ Municipalities can also tack on flat penalties and administrative fees. By the time you’re facing redemption, the number you owe can be far larger than the original bill.

The Notices You Will Get

Before the government can take a property, it has to notify you, and the law is specific about how.

When a municipality files a foreclosure petition, it must publish a public notice of foreclosure that lists every affected parcel, names the record owners, and states the final date to redeem. That final date must be at least six months after the notice is first published.⁵

Personal notice must also go to every owner and to anyone else with a recorded interest in the property. It goes out by both certified mail and regular first-class mail, on or before the day the public notice is first published. If both mailings come back undelivered within 45 days, the enforcing officer has to try to find an alternative address through the postal service. If that fails, a copy has to be physically posted on the property.⁶

The notice tells you what to do: pay by the redemption deadline, or file a verified answer with the county clerk and serve it on the tax district’s attorney by that same date. Do neither and you are permanently barred from any claim to the property.⁵

Foreclosure and the One-Month Window After Default

Once the redemption period expires without payment, the municipality files a petition of foreclosure in county court. The proceeding is “in rem,” which means it targets the property itself. No personal money judgment for the tax debt is entered against you.⁵ The government can take the property, but it cannot garnish your wages or come after your other assets for the unpaid amount.

If you don’t redeem and don’t answer by the deadline, a default judgment of foreclosure transfers title to the municipality. There is no right of redemption after that. The one narrow opening is a motion to reopen the default, and it has to be filed within one month after the judgment is entered. Courts hold that deadline strictly.⁷

You May Be Owed Money After the Sale

If the municipality later sells the foreclosed property for more than what you owed in taxes, interest, and costs, you can claim the surplus. The U.S. Supreme Court’s 2023 decision in Tyler v. Hennepin County settled the constitutional point, and New York’s Real Property Tax Law now includes a formal claim process.

Anyone who had a right or interest in the property immediately before the foreclosure judgment can file a claim with the court for a share of the surplus. For residential property, if no former homeowner has filed by the time the sale is confirmed, the proceeding stays open for at least three years from confirmation of the report of sale, and any claim filed within that window is timely. If the property was sold privately rather than at public auction, a former owner can ask the court to recalculate the surplus based on the property’s actual fair market value at the time of sale. Unclaimed surplus is eventually deemed abandoned and goes to the tax district to reduce its tax levy.⁸

For a homeowner who has lost a property to tax foreclosure, filing that claim promptly can mean recovering substantial equity that would otherwise be forfeited.

Ways to Stop or Slow the Clock

Several options exist to keep a delinquency from turning into a foreclosure. They work best when used early.

Installment Payment Agreements

Under Section 1184 of the Real Property Tax Law, local governments are authorized to adopt laws letting delinquent taxpayers spread payments over up to 36 months, on a monthly, bimonthly, quarterly, or semi-annual schedule. The local law can require a down payment of up to 25% of the delinquent amount. Interest keeps accruing on the balance, but the rate is locked in on the date you sign the agreement. Miss an installment by more than 30 days and you are in default on the agreement, which lets the municipality resume enforcement.⁹ Not every municipality has adopted a program, so ask your local tax office.

Lien Sale Exclusions in New York City

In New York City, certain exemptions keep a property out of the annual lien sale even when taxes are delinquent. Properties receiving the Senior Citizen Homeowners’ Exemption (SCHE) or the Disabled Homeowners’ Exemption (DHE) are excluded from the sale.² Getting approved for one of these exemptions before you fall behind is a genuine safety net.

Active-Duty Military Protection

If you are on active military duty, the federal Servicemembers Civil Relief Act blocks a tax sale of your property unless a court orders one and finds that your military service does not materially affect your ability to pay. A court can stay proceedings during your entire period of service and for up to 180 days after release. Interest on unpaid property taxes during service is capped at 6% per year, with no additional penalties allowed for nonpayment.¹⁰ In New York City, the Department of Finance will remove qualifying properties from any in rem foreclosure action or tax lien sale on application and will not pursue a sale until at least 180 days after military service ends.¹¹ These protections do not apply if you are not on active duty.
