Rockland County Property Tax Records Online

The Rockland County Department of Finance runs a property tax search tool on its website. You can look up assessment data, view tax bills, and make payments for any parcel in the county. The search is free. Enter an address, owner name, or tax map number to get started. Results include assessed values, exemptions, and tax amounts broken down by district.

Several Rockland County towns also run their own online payment portals. Orangetown uses a system at egov.basgov.com/orangetown where you can search by tax map number, address, or owner name. Ramapo has its own PROS system at townoframapo.prosgar.com that shows assessment information, property inventory, and comparable sales. Clarkstown's assessor's office provides its own search tools as well. Each town handles tax collection at the local level, though the county oversees the broader assessment framework.

Online payments typically carry small fees. Credit cards run about 2.45%. Electronic checks are cheaper, usually under a dollar. Visa debit cards have a flat fee around $3.95. These fees go to the payment provider, not to the county or town. If you prefer to avoid fees, you can pay by check through the mail or drop it off in person at the town clerk's office.

Rockland County GIS Maps and Tax Parcels

Rockland County provides GIS mapping that includes interactive and static maps for property research. The GIS system covers environmental data, planning layers, real property information, election districts, zoning, and tax maps. You can view parcel boundaries, look up ownership, and get basic assessment data just by clicking on a map location.

The county also participates in the NYS Statewide Parcel Map Program. This state-level GIS portal publishes updated parcel data for all New York counties, including Rockland. The data gets refreshed annually and is available as web services or downloadable files. It is useful for comparing parcels across town lines or looking at broader trends in assessed values across the county.

Tax maps are the official record of parcel boundaries. Each parcel has a unique tax map number used by the assessor, the county clerk, and the tax collection offices. If you need a printed copy of a tax map, contact the Real Property Tax Department at (845) 638-5131. Maps can also be viewed through the GIS portal online.

Rockland County Property Tax Assessments

Local assessors in each Rockland County town set property values based on market data. The Residential Assessment Ratio, or RAR, varies by town and is issued annually by the NYS Office of Real Property Tax Services. For instance, Orangetown's RAR was 29.52 in 2025. That means a home assessed at $218,000 would have an assumed market value of roughly $738,000. The RAR goes up when the market drops and comes down when values rise.

The tentative assessment roll publishes on May 1 in most Rockland County towns. Property owners have until Grievance Day, typically the fourth Tuesday in May, to file a challenge using the RP-524 form. The Board of Assessment Review in each town hears complaints and decides whether to adjust the assessment. If you disagree with their decision, you can pursue Small Claims Assessment Review or an Article 7 proceeding in court under the Real Property Tax Law.

Exemption applications must be filed by March 1. Common exemptions include STAR for school tax relief, senior citizen exemptions under RPTL Section 467, veterans exemptions under RPTL Sections 458 and 458-a, and exemptions for agricultural, solar, and nonprofit properties. The assessor's office in your town can help with forms and answer questions about which programs you qualify for.

Rockland County Tax Foreclosure and Delinquent Taxes

The county posts a list of properties up for auction on its website, and interested buyers can review the terms before the sale date. These auctions are open to the public.

Delinquent tax penalties accrue monthly. Town and county taxes are typically due in January or February. School taxes are due in September or October.
