New York Property Appraiser: Records, Values & Appraisal Guide

by
Independent guide: OrangeCountyPropertyAppraiser.us is an independent informational resource. This page covers New York property assessment records, values and appraisal terminology. New York does not have one statewide “Property Appraiser” office like Florida counties do. Most assessment work is handled by local city, town or village assessors; New York City uses the Department of Finance; Nassau County has its own Assessment Review Commission process. Use official government websites for current records, forms, appeal deadlines, tax bills and deed searches.

Search New York Property Records, Understand Assessments & Find the Correct Appraisal Office

People often search for “New York Property Appraiser,” but the official New York term is usually assessor. Outside New York City, start with your local assessment roll, county real property tax office or municipal assessor. In New York City, start with the Department of Finance Property Information Portal. For deeds and mortgages, use the county clerk, county register or ACRIS where applicable.

This guide gives you the practical route: find the parcel, save the tax map number or BBL, read assessment and full-value fields correctly, check STAR and exemptions, file a grievance when needed, and avoid confusing an assessment record with legal title.

Start here: New York property appraisal is local

In New York State, assessments are determined by local assessors who estimate the value of real property in a city, town or village. The New York State Office of Real Property Tax Services provides statewide guidance, forms, systems, equalization support and assessor resources, but the property record you need usually starts with the local assessing unit.

Outside NYC

Find the local assessment roll

Open the state’s local assessment roll page, choose the county and city/town/village, then use the local roll or county property search to find the parcel.

New York City

Use NYC DOF property tools

For Manhattan, Brooklyn, Queens, Bronx and Staten Island assessment data, start with NYC Department of Finance and the Property Information Portal.

Use recording offices

Assessment records are not title records. Use county clerks/registers, or ACRIS for Manhattan, Brooklyn, Queens and Bronx documents from 1966 forward.

Do not import Florida terms: New York does not use Florida-style Property Appraiser, TRIM, Save Our Homes, portability or Value Adjustment Board language. Use New York terms: assessor, assessment roll, tentative roll, final roll, Grievance Day, Board of Assessment Review, SCAR, Article 7, STAR, tax map number, SBL and BBL.

Which New York office handles your property task?

Use the office that owns the task. The assessor does not record deeds, the clerk does not set assessments, and a tax collector cannot usually change value because the bill feels too high.

New York property identifiers: SBL, tax map number, parcel ID and BBL

New York property research often starts with an address but becomes easier after you save the tax-map identifier. This identifier connects assessment rolls, exemptions, tax bills, maps, grievance forms and recorded-document research.

Property Key New York State homeowner benefit and STAR workflows when requested. Do not guess it. Use the official Tax Department account or letter when required.

New York values: market value, assessment, level of assessment and exemptions

New York assessment records can show market value, full value, assessed value, taxable assessed value, property class, exemptions and prior-year tax information. The assessment is one component of the tax bill; the tax levy and rate are set through local budgets.

Market / full valueAssessor’s value estimate
Level of assessmentUniform percentage in the assessing unit
Assessed valueValue placed on the roll
Taxable value × rateBill varies by jurisdiction
Value terms

What the record means

  • Market value or full value is the assessor’s estimate of property value, not an online home-price estimate.
  • Assessed value is the value placed on the assessment roll based on the local level of assessment.
  • Taxable assessed value can be lower because of exemptions or special rules.
  • Tax bill depends on budgets, levies, tax rates, exemptions, special districts and local billing rules.
Common mistakes

Do not assume

  • Do not read assessed value as the full market value unless the level of assessment is 100%.
  • Do not appeal only because the tax bill increased.
  • Do not treat a tax map as a survey.
  • Do not treat an owner line as a title report.
  • Do not file New York City or Nassau County appeals using the wrong statewide grievance route.

How assessment value connects to a bill

Full Value Assessor’s market-value estimate $400,000 example Assessment Value placed on the roll $200,000 at 50% LOA Tax Bill After levy, rate and exemptions Example only. Check your local roll, tax bill and collector record before making financial decisions.
Useful full-value check: if a property is assessed at $200,000 and the level of assessment is 50%, the implied full value is $400,000. If the level of assessment is 100%, the assessed value and full value may match.

New York property tax cycle: roll, grievance, final roll and bills

Specific dates vary by locality, so always confirm the official date with the assessor or local roll. In many communities outside NYC, the tentative roll appears around May 1, Grievance Day is the fourth Tuesday in May, and the final roll is filed around July 1. School tax bills are commonly issued near the beginning of September, and county/town tax bills often arrive in early January.

Valuation datePrice level for the assessment cycle is fixed.
Taxable status dateOwnership, condition and exemptions are measured for the roll.
Tentative rollCheck assessment, market value and exemptions early.
Grievance DayFormal complaint deadline in many communities.
Final rollTax bills are based on final roll information.
Tax billsSchool, county, town, city and special district billing varies.
Deadline rule: if you miss the administrative grievance deadline, you may lose the opportunity for administrative and judicial review for that assessment year. New York City and Nassau County have separate review systems and deadlines.

New York City property records: DOF, NOPV, Tax Commission and ACRIS

New York City has its own property assessment and recording structure. The Department of Finance values property every year, publishes assessment rolls, sends the Notice of Property Value, maintains tax maps and provides the Property Information Portal. The NYC Tax Commission is the independent forum for assessment challenges. ACRIS is the main online recording search for Manhattan, Brooklyn, Queens and Bronx documents from 1966 to the present.

STAR, exemptions and property tax relief

New York property-tax benefits are not the same as Florida Homestead. The most searched benefit is STAR, which provides school property tax relief to eligible homeowners. New homeowners generally register for the STAR credit with New York State rather than applying for a new STAR exemption with the local assessor.

STAR credit

New homeowners start here

If you are a new homeowner or are not receiving a STAR benefit on your current home, register with New York State when the property becomes your primary residence.

Open STAR resource center
2026–2027 base amounts

Basic and Enhanced STAR

New York State’s STAR calculation page lists the 2026–2027 Basic STAR base amount as $30,000 and the Enhanced STAR base amount as $88,500. Actual savings vary by locality.

Check STAR calculation rules
Other exemptions

Local filing still matters

Senior, veteran, disability, agricultural, nonprofit and other exemptions can require local forms, proof and deadlines. Use the assessor and current state form page.

Open exemption forms

How to handle exemptions safely

  1. Find the property’s assessing unit and parcel identifier.
  2. Open the local assessor page or assessment roll.
  3. Check which exemptions already appear on the record.
  4. For STAR, use the official Tax Department STAR page and Homeowner Benefit Portal instructions.
  5. For local exemptions, use the current state form and the local assessor’s filing instructions.
  6. Confirm the taxable status date or local deadline before waiting.
  7. Save proof of submission and later verify the exemption on the roll or bill.
Important filing note: the state form page warns users not to file exemption applications with the New York State Department of Taxation and Finance or ORPTS unless the specific state program instructs them to do so. Local exemptions generally go to the assessor.

How to challenge a New York property assessment

New York State says property owners are eligible for formal review of their assessment. Outside New York City and Nassau County, the normal local route is to file Form RP-524, Complaint on Real Property Assessment, with the assessor or Board of Assessment Review by the local deadline. After the local board decision, qualifying homeowners may be able to use Small Claims Assessment Review, and other cases may proceed through Article 7 in State Supreme Court.

Outside NYC/Nassau

Board of Assessment Review

Use RP-524, attach supporting evidence, and file by Grievance Day. Contact the assessor for the exact deadline and accepted filing method.

Open grievance forms
SCAR

Small Claims Assessment Review

SCAR is a court review option for many owner-occupied one-, two- or three-family homes after the administrative review step. The court filing fee is listed as $30.

Open SCAR information
Article 7

State Supreme Court review

Article 7 tax certiorari is a judicial route. New York State guidance says it generally must be filed within 30 days after the final assessment roll filing or notice rule.

Open grievance procedure

Assessment grievance workflow

  1. Open the tentative assessment roll as soon as it is published.
  2. Write down the assessing unit, tax map number/SBL/BBL, property class, full value, assessed value and exemption status.
  3. Identify the real problem: overvaluation, unequal assessment, exemption denial, misclassification, inventory error or local tax-rate concern.
  4. If outside NYC and Nassau, open Form RP-524 and instructions.
  5. Prepare evidence: comparable sales, appraisal, photos, repair estimates, income/expense support, floor plans, survey or factual correction documents.
  6. File with the assessor or Board of Assessment Review by the local Grievance Day deadline.
  7. Attend or respond to the hearing process as instructed.
  8. Review the BAR decision. If needed, evaluate SCAR or Article 7 deadlines quickly.
Issue Stronger evidence Weaker argument
Market value Comparable sales adjusted for location, date, size, condition and property type. One online estimate or a neighbor’s opinion.
Assessment ratio / equity Assessment roll comparisons using similar properties and the same assessing unit. Comparing properties from different towns, school districts or classes without adjustment.
Condition Dated photos, inspection notes, repair estimates and contractor documents. “The house needs work.”
Property facts Floor plan, survey, permit record, measurements or official correction request. Unsupported square-footage or acreage claim.
Exemption denial Application copy, denial notice, residency proof, age/income/disability proof where required. Assuming the prior owner’s benefit automatically carries over.
Tax bill too high? New York State guidance says if your assessment is accurate but taxes are still too high, address the taxing jurisdictions that impose taxes, such as school board, county legislature, city council, town board, fire district or special districts. A grievance is mainly about the assessment, not local budgets.

Property tax bills and payments in New York

Outside NYC, most New York taxpayers receive separate property tax bills during the year, commonly including a school tax bill and a county/town or city bill. In NYC, property tax bills and payments are handled through the Department of Finance. The assessment record helps explain the bill, but the current payment balance comes from the billing or collection office.

Assessment side

Assessor / ORPTS / DOF

  • Values real property.
  • Creates tentative and final assessment rolls.
  • Administers exemptions through local or state processes.
  • Handles value review before the appeal deadline.
Billing side

Collector / receiver / treasurer / NYC DOF

  • Issues tax bills.
  • Processes payments and receipts.
  • Handles late charges, installment rules and balances.
  • Answers current payment-account questions.
  1. Find the property identifier from the assessment roll or property portal.
  2. Identify the taxing jurisdiction: school district, town, city, village, county or NYC.
  3. Open the official collector, receiver, treasurer or NYC DOF payment page.
  4. Search by parcel ID, SBL, BBL, bill number, property address or owner name if allowed.
  5. Verify tax year, installment, balance, penalty, interest, escrow status and convenience fees.
  6. Save confirmation and download the receipt when the system provides one.
Escrow note: if your mortgage servicer pays property taxes, you may receive receipts instead of bills, or the lender may receive payment information. Always check the official collector record before assuming a bill is paid.

Deeds, mortgages, liens and recorded land documents

An assessment roll can identify a property, but it is not a legal title report. Outside NYC, deeds and mortgages are generally filed with the county clerk or county recording office. In New York City, ACRIS covers Manhattan, Queens, Bronx and Brooklyn from 1966 to present, while Staten Island property documents are searched through the Richmond County Clerk.

Recorded documents

County clerk, register or ACRIS

Use recorded-document systems for deeds, mortgages, satisfactions, liens, easements, powers of attorney, transfer reports, recording dates and certified copies.

Assessment display

Not a title search

Owner information in a tax roll may lag behind recorded documents and is not title insurance, a lien search, a boundary survey or a legal ownership opinion.

  1. Use the assessment record to confirm county, municipality or borough, address and parcel identifier.
  2. Open the correct recording office: county clerk/register outside NYC, ACRIS for Manhattan/Brooklyn/Queens/Bronx, or Richmond County Clerk for Staten Island.
  3. Search by grantor/grantee, party name, document type, document ID, file number, recording date or parcel identifier if supported.
  4. Open likely documents and compare names, property description, recording date and tax map or BBL references.
  5. Order certified copies only through the official recording office if a court, lender, title company or government agency requires certification.
  6. Use a title professional, surveyor or attorney for title, lien, boundary or easement conclusions.

Deed-fraud watch: NYC offers a Notice of Recorded Document system that can notify owners when deed- or mortgage-related documents are recorded against a BBL. A notice is not prevention, so review suspicious recordings promptly through official channels.

New York assessment math and task router

These browser tools are educational only. They do not collect personal data, file a grievance, pay a bill, calculate every exemption or replace the official assessment roll, tax bill or collector record.

Full value and tax-rate estimate

Use the level of assessment field from your local roll. If your municipality assesses at 100%, enter 100. For tax rate, enter dollars per $1,000 of taxable assessed value if that is how your local bill shows it.

$200,000 assessment at a 50% level of assessment implies $400,000 full value. At $25 per $1,000, the illustrative tax is $5,000 before exemptions or local adjustments.

Common New York property-record problems

Address search does not find the property

Confirm the city, town, village or borough first. Then search by tax map number, SBL, parcel ID or BBL. A mailing city, school district, ZIP code or postal address may not match the assessing unit.

The assessed value looks much lower than the market value

Check the level of assessment. Some assessing units assess at a percentage of market value. Divide assessed value by the level of assessment percentage to estimate full value.

The tentative roll and tax bill do not match

The tentative roll is proposed assessment information. The final assessment roll is used for tax bills. Check the roll year, final roll date, exemptions and local collector record before assuming an error.

I missed Grievance Day

Contact the assessor immediately to confirm whether any correction route exists. For formal assessment review, missing the deadline can prevent administrative and judicial review for that assessment year.

The owner name is old after a sale

Check the county clerk/register or ACRIS for the recorded deed. Assessment records may reflect roll timing or processing delays. Do not record a new deed simply because an online assessment display has not updated.

The tax map boundary looks wrong

Use maps for research and orientation only. For legal boundaries, easements, encroachments or title disputes, use recorded documents, a licensed surveyor, a title professional or an attorney.

Official resources and verification

Use these official sources for current New York assessment records, forms, appeal procedures, STAR rules, tax bills, NYC records and recorded documents. Recheck deadlines, forms, benefit amounts and portal instructions before filing or paying.

New York Property Appraiser FAQs

1. Does New York have a statewide Property Appraiser?

No. “Property Appraiser” is a common search phrase, but New York property assessment is usually handled by local city, town or village assessors. New York City uses the Department of Finance, and Nassau County has its own assessment review process.

2. What is the official way to search New York property assessments?

Outside New York City, use the New York State “Check your assessment” page to find the local assessment roll, then search the county or municipal record. In New York City, use the Department of Finance Property Information Portal.

3. What is SBL in New York property records?

SBL usually means Section-Block-Lot. Many New York counties and municipalities use SBL, tax map number or parcel ID to identify property on assessment rolls, tax maps, bills and grievance forms.

4. What is BBL in New York City property records?

BBL means Borough-Block-Lot. It is the main New York City parcel identifier used in Department of Finance property tools, tax maps, ACRIS and many NYC property-record workflows.

5. What is the difference between full value and assessed value in New York?

Full value is the assessor’s market-value estimate. Assessed value is the value placed on the roll based on the local level of assessment. If the level of assessment is not 100%, assessed value and full value will not be the same.

6. When is Grievance Day in New York?

In most communities outside New York City and Nassau County, Grievance Day is the fourth Tuesday in May. Dates can vary, so confirm the exact deadline with the local assessor or assessment roll notice.

7. What form do I use to grieve a New York assessment?

Outside New York City and Nassau County, the usual state form is RP-524, Complaint on Real Property Assessment. File it with the assessor or Board of Assessment Review by the local deadline and include supporting evidence.

8. How do I challenge a New York City property assessment?

Use the New York City Tax Commission, not the normal local Board of Assessment Review route. File the correct Tax Commission application for your property tax class and verify the current deadline on the official Tax Commission website.

9. Where do I pay New York property taxes?

Property tax payments go to the local collector, receiver of taxes, county treasurer, school tax collector or NYC Department of Finance, depending on the property location and bill. Use the official payment system shown by the bill or local government.

10. Where do I find New York deeds, mortgages or liens?

Use the county clerk, county register or county recording office. In New York City, use ACRIS for Manhattan, Brooklyn, Queens and Bronx records from 1966 forward, and use the Richmond County Clerk for Staten Island records.
