Tompkins County Property Tax Records
Tompkins County property tax records are maintained by the Real Property Tax Services office in Ithaca. The county seat is Ithaca, home to Cornell University and Ithaca College, which means a large share of property in the county is tax-exempt. The Real Property office keeps assessment rolls, tax maps, and sales data for every parcel in the county's nine towns and one city. You can search these records online, visit the office in person at the county administration building, or request information by mail. Most online searches are free and do not require an account.
Tompkins County Property Tax Overview
Search Tompkins County Property Tax Records
The Tompkins County Real Property Tax Services office provides online access to assessment data for all parcels in the county. The department uses the Image Mate Online system, which is common across many New York counties. You can search by owner name, property address, or tax map number. Results show assessed values, property class codes, lot dimensions, and any exemptions on the parcel. The system is free to use and does not need a login.
If you prefer to look up records in person, the Real Property office is at the Tompkins County administration building in downtown Ithaca. Staff can pull up records, print assessment data, and answer questions about how your property was valued. The Tompkins County Clerk's Office also keeps land records including deeds, mortgages, and liens that tie into the property tax records. These offices work together when property transfers happen.
The state Municipal Data Portal lists contact information for each Tompkins County town assessor. It also links to local search tools and provides equalization rates by municipality. The SalesWeb database offers ten years of property sales data for Tompkins County, updated weekly from RP-5217 transfer reports filed with the county clerk.
Property Tax Assessments in Tompkins County
Each town in Tompkins County has a local assessor who sets property values. The assessor reviews recent sales, building permits, and market conditions to come up with an assessed value for every parcel. Under the Real Property Tax Law, the tentative assessment roll publishes on May 1. That gives property owners time to review their number before the final roll is set.
The county Real Property Tax Services office supports local assessors with data collection, sales verification, and appraisal assistance. The Director of Real Property Tax Services also maintains tax maps for the entire county and provides training to local boards of assessment review. Tax map maintenance is an ongoing task, since parcels split, merge, and change hands throughout the year. Each parcel has a unique tax map number that links to the assessment database.
Tompkins County participates in the NYS Statewide Parcel Map Program. Parcel data gets updated annually and is available for download or as web services through the state GIS portal. This data is useful for looking at property tax records across town boundaries or for doing a broad search of assessed values in the county.
Tompkins County Tax Grievances and Exemptions
If you think your property assessment is too high, talk to the local assessor first. Many issues get resolved at that stage. If you still disagree, file an RP-524 form on Grievance Day. In most Tompkins County towns, Grievance Day falls on the fourth Tuesday in May. The Board of Assessment Review hears your case and makes a decision. If you are not satisfied, you can take the matter to Small Claims Assessment Review or file an Article 7 proceeding in court.
Common exemptions in Tompkins County include STAR for school tax relief, senior citizen exemptions under RPTL Section 467, veterans exemptions under RPTL Sections 458 and 458-a, and agricultural exemptions for qualifying farmland. Ithaca's large share of tax-exempt institutional property means that taxable parcels often carry a heavier burden. That makes it especially important for homeowners to check that their assessments are fair and that they are getting every exemption they qualify for.
Exemption applications are due by March 1 in most towns. The Check Your Assessment page on the state Department of Taxation and Finance site explains the full process step by step. It also links to the Municipal Data Portal where you can find your town assessor's contact information.
Note: Tompkins County has a large share of tax-exempt property due to Cornell University and other institutions, which affects the tax rate for remaining taxable parcels.
Tompkins County Delinquent Taxes and Foreclosure
Delinquent property taxes in Tompkins County are handled through the county treasurer's office. Town and county taxes are typically due in January or February. School taxes come due in September or October. If you miss the deadline, interest and penalties start accruing. The county uses RPTL Article 11 enforcement procedures for collecting unpaid taxes, which can eventually lead to foreclosure if the debt is not resolved.
Properties that go through foreclosure may end up at a county auction. The county posts a list of available properties before the auction date. Interested buyers should review all terms and do their own title research before bidding. Once you buy a property at auction, you take it as-is.
The Real Property Tax Law sets out the rules for enforcement of delinquent taxes across all New York counties, including Tompkins. RPTL Article 11 covers the notice requirements, redemption periods, and foreclosure procedures that the county must follow.
