Updated September 2026. No 2026-27 rate is posted. The newest rates Finance publishes are labelled tax year 2026, and its Class 2 guide says a year’s rate is set by the City Council and not finalized until November, so that is what the table below carries. On the January 15, 2026 tentative roll, Staten Island class 1 homes took the largest percentage increase in assessed value of any borough, up 5.1 percent. The surcharge exemption deadline is October 6, 2026, covered in the surcharge, explained.

Staten Island is Richmond County, and in a borough-block-lot number it is borough code 5. That is close to all that makes its property tax local, because the rates and the rules are citywide. The roll is what differs, and Staten Island’s is unlike any other. Our primer, how NYC property tax works, has the arithmetic.

What is a Staten Island property tax bill made of, and is there a borough rate?

There is no Staten Island property tax rate. Finance sets the rate by tax class, four of them, applied identically in all five boroughs, so a house in Great Kills pays what a house in Bayside pays. The counts below are Staten Island’s share of the FY2027 tentative roll, 130,979 lots, from the Finance roll summary.

The class 1 rate was 20.085 percent in tax year 2025, so it fell while assessed values rose. Caps reach class 1 and, inside class 2, only 2a, 2b and 2c; an eleven-unit rental on Bay Street has none and is phased in instead.

Three things differ by borough: the market values Finance models from local sales, the class mix, and the housing stock. Staten Island is the outlier on class mix, 92.7 percent of its lots in class 1 on the tentative roll against 77.3 percent in Queens, 66.8 in the Bronx, 62.3 in Brooklyn and 3.9 in Manhattan. A borough of 109,205 one- to three-family houses behaves differently under caps than a borough of rental towers.

How does Finance value a Staten Island home?

Finance does not appraise a one-, two- or three-unit house. It “uses statistical modeling to analyze prices of similar properties (based on factors such as size and location) that sold in your neighborhood in the prior three years.” That value is multiplied by the level of assessment, 6 percent for class 1, and state law caps the increase at 6 percent a year and 20 percent over five.

The cap is where a Staten Island house and its sale price part company, and the gap is measurable. Take the 70,158 one- to three-family homes on the FY2027 tentative roll carrying no exemption at all. Their median market value is $774,000, and 6 percent of that, $46,440, is exactly their median actual assessed value. Their median billable assessed value is $35,783, and 68,152 of them, 97 percent, are billed on less than the uncapped 6 percent figure. A house held twenty years is taxed on an assessment that never caught up. A house bought last year is not, and its owner is usually the one who calls us. The cap also sets the number an appeal must beat, the effective market value, which our guide to the Notice of Property Value sets out field by field.

The smaller stock is valued another way. Class 2 is valued as income-producing, co-ops and condos as though they were rentals, and class 4 on income potential and expenses, all resting on the owner’s Real Property Income and Expense filing, required above $40,000 of actual assessed value on the tentative roll. RPIE-2025 was due June 1, 2026, and a careless filing on Hylan Boulevard becomes next year’s assessment. We run RPIE filing as its own service.

What does the FY2027 tentative roll say about Staten Island?

Finance published the roll on January 15, 2026. Citywide market value reached $1.659 trillion, up 5.4 percent; class 1 gained 5.2 percent, to $822.2 billion, with assessed values up 4.7 percent to $28.2 billion. The borough line is short. “Staten Island had the greatest percentage increase in assessed value, up 5.1 percent,” the release says of class 1 homes, with Queens at 4.9 and Brooklyn at 4.5. Values reflect activity from January 6, 2025 to January 5, 2026, the taxable status date.

The release gives borough percentages, not dollars, so no dollar total for Staten Island appears here. The roll file does carry a borough record: 8,200 vacant land lots, more than any other borough.

How do you look up a Staten Island property tax bill or property records?

Start with the borough-block-lot number, because every city system is keyed to it, and a Staten Island BBL begins with 5. The Property Information Portal holds the assessment record for any lot. Finance’s Property Tax Public Access portal searches by address or BBL and holds the bills, notices, tax class, market value and exemptions.

Deeds are the local exception. Finance says its business centers “receive deeds and mortgages for recording (except for Staten Island).” Richmond County records its own, at the Richmond County Clerk’s Office, 130 Stuyvesant Place, “for Richmond County only.” ACRIS serves the other four boroughs.

When are the Staten Island deadlines and due dates?

Almost every Staten Island homeowner is a quarterly payer. Bills go quarterly at an assessed value of $250,000 or less, semi-annually above it, and only 162 of the borough’s 123,956 class 1 records in the Finance assessment file on Open Data carry an actual assessed value above that line. Quarterly payers get a grace period to the 15th.

How does a Staten Island homeowner appeal an assessment?

Two agencies, two filings, not interchangeable. Finance takes a wrong description or a market value error on a Request for Review, due March 15 for class 1 and April 1 for other classes, and calls it “not a substitute for appealing your property’s assessed value with the Tax Commission.”

The appeal itself goes to the New York City Tax Commission, an independent agency that can cut the assessment, change the tax class and adjust exemptions. If the property has an effective market value, the case turns on proving it is worth less than that figure. The Application for Correction must be received by March 15 for class 1 and March 1 for classes 2, 3 and 4; later applications “will not be granted.” The commission takes an application in person or by mail, and no Staten Island owner needs to cross the harbor: it lists the Staten Island Business Center, 350 St. Marks Place off Hyatt Street in St. George, first floor, as a filing location.

Past the commission the route is judicial, which is tax certiorari. The sequence is in our guide to the property tax appeal process in New York City. We run both filings: Tax Commission appeals and Finance Department appeals.

Which exemptions and abatements matter most on Staten Island?

STAR and Enhanced STAR. New York State runs both. Finance no longer administers them or takes applications, so a claim goes to the state’s Homeowner Benefits Portal.

Senior Citizen Homeowners’ Exemption. All owners must be 65 or older unless they are spouses or siblings, combined income cannot exceed $58,399, and the date to apply or renew is March 15.

Disabled Homeowners’ Exemption. The same $58,399 ceiling, for disabled owners of one-, two- or three-family homes, condominiums or co-op apartments. It cannot be held with SCHE, and an owner qualifying for both receives SCHE.

Veterans. The Alternative Veterans Exemption covers veterans of foreign wars, expeditionary medalists, veterans with honorable discharges, spouses and surviving spouses, and Gold Star parents, with Cold War veterans eligible from December 2025. Deadline March 15.

Co-op and condo abatement. Unit owners cannot apply; the board applies for the whole development. The benefit runs from 28.1 percent of the tax at an average assessed value of $50,000 or less down to 17.5 percent at $60,001 and above, for a primary residence bought by January 5. Staten Island carries 3,121 condominium unit lots in class 2, the tax class the abatement requires.

ICAP. Among the borough’s 5,500 class 4 lots on the tentative roll, this abates taxes for up to 25 years on eligible buildings built, modernized, expanded or improved, against spending of at least 30 percent of taxable assessed value within four years of the permit. Staten Island is named among the areas carrying extra benefits. More is in NYC tax abatements explained, with 421-a, 485-x and J-51.

One charge runs the other way, and Staten Island is barely exposed. The non-primary residence surcharge, effective May 28, 2026, reaches one- to three-family homes Finance values above $5 million and condominium or co-op units at $1 million or more, for tax years 2026-27 and 2027-28. Only 23 Staten Island one- to three-family homes clear $5 million on the FY2027 tentative roll, and 105 of its condominium units reach $1 million, though Finance sets surcharge exposure from the supplemental market value roll it published on July 24, 2026.

Staten Island property tax questions, answered

Is there a Staten Island property tax rate?

No. Finance sets one rate per tax class citywide. A Staten Island house pays the class 1 rate, 19.843 percent for tax year 2026, exactly what a Queens or Bronx house pays.

What is the property tax rate for a Staten Island house?

19.843 percent for tax year 2026, applied to assessed value, not market value. No 2026-27 rate has been adopted as of September 2026.

How do I find my Staten Island property tax bill or tax records?

Search Finance’s Property Tax Public Access portal by address or borough-block-lot, with 5 as the borough code. Deeds go to the Richmond County Clerk, not the city register.

When is the deadline to appeal a Staten Island assessment?

March 15 for class 1, which covers most Staten Island lots, and March 1 for classes 2, 3 and 4. Both roll to the next business day on a weekend, as in 2026.
