Rockland Property Tax: Rates, Deadlines & Appeals (2026)

Direct answer: Rockland County does not run one countywide assessment appeal office. You file Form RP-524, Complaint on Real Property Assessment, with the assessor or Board of Assessment Review (BAR) in the town where your property is assessed: Clarkstown, Haverstraw, Orangetown, Ramapo or Stony Point. The 2026 town grievance deadline was Tuesday, May 26, 2026—the 4th Tuesday in May; as of October 2026, the next regular town Grievance Day is expected to be Tuesday, May 25, 2027. (tax.ny.gov)

How assessments work in Rockland County

Rockland assessments are local. The five town assessors—not the County Finance Department—set the assessed values that later feed county, town, school, village and special-district tax bills. Clarkstown, Orangetown and Stony Point publish the same basic annual cycle: July 1 valuation date, March 1 taxable-status/exemption deadline, May 1 tentative roll, 4th Tuesday in May Grievance Day, and July 1 final roll. For the 2026 roll, the valuation date was generally July 1, 2025, taxable status was March 1, 2026, and final rolls were filed around July 1, 2026. (clarkstown.gov)

Rockland towns do not all assess at the same percentage of market value. For the 2026 county apportionment, Rockland adopted these equalization ratios: Clarkstown 21.15%, Haverstraw 49.26%, Orangetown 31.89%, Ramapo 7.54%, Stony Point 9.36%. That is why a Ramapo assessment may look much lower than an Orangetown assessment for a similarly priced house; compare market value, not just assessed value. (legislature.rocklandcountyny.gov)

Whether you should appeal

Appeal if your tentative assessment implies a market value above what your home could have sold for on the valuation date, or if similar homes are assessed more favorably. The most useful proof in Rockland is local and specific: 3–5 comparable sales near July 1, 2025 for a 2026 grievance, a recent appraisal, closing statement, broker price opinion, condition photos, contractor estimates, or evidence that the assessor’s record has the wrong living area, style, condition, finished basement or number of units.

Do not appeal simply because your tax bill is high. New York’s formal grievance reviews the assessment, not the budgets adopted by the county, town, school district or fire/sewer districts. NYS Tax says there is no cost to grieve an assessment and you do not need a lawyer, but if you lose at the BAR and pursue Small Claims Assessment Review (SCAR), the court filing fee is $30. (tax.ny.gov)

I did not find an official Rockland County or town-published 2026 success rate, median reduction or win-rate table for residential grievances. Treat any private mailer’s success claims as marketing unless it shows town-specific filed-case data.

Step-by-step how to file

1. Find your town roll and implied market value. Use your town’s 2026 tentative/final roll or assessor lookup. Divide your assessed value by your town’s residential ratio or level of assessment to estimate the full market value the town is placing on your home.

2. Use the official form. The form is NYS Form RP-524, Complaint on Real Property Assessment. If a representative files for you, complete the representative authorization in the form. Ramapo also publishes an informal Request for Assessment Review / TRAR form for pre-roll review, but the formal appeal is still RP-524 during the grievance period. (tax.ny.gov)

3. File in the correct town—there is no Rockland countywide portal. Safe filing is paper delivery or mail to the town assessor/BAR. New York allows electronic grievance filing only where the assessing unit has opted in and published instructions; do not assume email is valid unless that town’s current-year notice says so. Mailed grievances must be received by Grievance Day, not merely postmarked. (tax.ny.gov)

Town filing locations:

• Clarkstown Assessor, 10 Maple Ave., New City, NY 10956; assessor@clarkstown.gov; phone 845-639-2031. (clarkstown.gov)
• Haverstraw Assessor, Town Hall, 1 Rosman Road, Garnerville, NY 10923; assessor@townofhaverstraw.org; 845-942-3717. Haverstraw’s page says grievances can be filed in 2026 but also contains a conflicting “May 28” line; because the statutory/town calendar rule is 4th Tuesday, confirm any later date directly before relying on it. (townofhaverstraw.org)
• Orangetown Assessor / BAR, Orangetown Town Hall, 26 Orangeburg Road, Orangeburg, NY 10962. (orangetown.com)
• Ramapo Assessor, 237 Route 59, Suffern, NY 10901; townoframapoassessor@ramapo.gov. Ramapo’s 2026 notice required RP-524 and supporting documents to be filed at the Assessor’s Office by 8:00 p.m. May 26, 2026; mailed forms had to be received by that date. (ramapo.gov)
• Stony Point Assessor, 74 E. Main St., Stony Point, NY 10980; assessor@townofstonypoint.org; 845-786-2716 ext. 117. Stony Point’s 2026 page states grievances could be filed May 1–May 26, 2026. (stonypointny.gov)

4. Attach proof, not a speech. Put your requested assessment on RP-524, show your math, and attach a concise comparable-sales grid. If your house has defects, include photos and repair estimates.

What happens after

The hearing body is the town Board of Assessment Review. It is appointed locally, generally has three to five members, and cannot include the assessor or assessor’s staff. You may appear, use a representative, or in many towns let the BAR decide on your written submission. A typical residential hearing is short: the board checks whether your complaint was timely, reviews your comps/appraisal and the assessor’s explanation, may ask questions, and then deliberates later. (tax.ny.gov)

The BAR sends a written Notice of Determination stating whether your tentative assessment was reduced and why. If you disagree, an eligible owner-occupied one-, two- or three-family homeowner may file SCAR in New York Supreme Court; the deadline is generally 30 days after the final assessment roll is filed or notice of filing, whichever is later. In Rockland towns with July 1 final rolls, that usually means the end of July. (tax.ny.gov)

Local tips

Check exemptions before you grieve. March 1 is the normal Rockland town exemption deadline. Common homeowner exemptions include STAR, Enhanced STAR, senior citizens, limited-income disability, veterans, volunteer firefighter/ambulance, agricultural and solar exemptions. For 2026–2027, NYS certified Rockland Basic STAR exemption amounts ranging from $4,690 in Ramapo to $32,600 in Haverstraw, with Enhanced STAR amounts higher. (clarkstown.gov)

Worked savings example using Rockland’s actual county tax. Suppose a Ramapo homeowner’s 2026 assessment is $60,500. Using Ramapo’s 2026 residential assessment ratio from the notice, about 6.05%, that implies roughly $1,000,000 market value. If strong comparable sales support $900,000, the target assessment is $54,450, a reduction of $6,050. Rockland’s 2026 county levy for Ramapo was $46,048,115 on $1,840,225,328 taxable assessed value, an actual county rate of about $25.023 per $1,000 of assessed value. County-tax savings alone would be about $151 for the year; the total savings would be higher once Ramapo town, school and applicable special-district rates are applied. (legislature.rocklandcountyny.gov)

File early. The deadline is jurisdictional. If your town offers email, fax, drop box or e-filing in a current notice, keep proof of successful receipt. Otherwise, hand-deliver or use a tracked mailing early enough that the assessor actually receives RP-524 before Grievance Day.

When Are Property Taxes Due in Rockland County?

County & Town tax is collected by the Receiver of Taxes in each town from January 1 through March 31; payments are interest-free in January, have 1% interest in February, and 2% interest in March. If not paid to the Receiver by March 31, the account is turned over to the Rockland County Commissioner of Finance on April 1, with a 5% penalty and 1% interest per month or part of a month from February 1 until paid. Quarterly County & Town tax installment plan: January 15 to the town Receiver, then April 15, July 15, and October 15 to the Rockland County Commissioner of Finance; Rockland County states the quarterly plan has a 5% service charge, and failure to make a quarterly payment makes the unpaid balance due with 5% penalty plus 1% monthly interest.

This is not the same as the assessment appeal deadline above. The appeal deadline is your window to contest your assessed value; the payment due date is when the resulting tax bill must be paid. Missing one does not affect the other, but missing either has real consequences — one forfeits your right to appeal for the year, the other can trigger penalties and interest.

Property Tax Exemptions in Rockland County

• STAR / School Tax Relief — Owner-occupied primary residences that meet New York STAR eligibility rules; new homeowners and first-time STAR applicants receive the STAR credit rather than a new STAR exemption, while existing STAR exemption recipients may continue the exemption. The NYS Tax Department publishes Rockland County STAR savings by municipality, school district, and tax class.. Benefit varies by municipality, school district, and tax class; the NYS 2025 Rockland County table lists final Basic STAR and Enhanced STAR credit/exemption savings amounts for each jurisdiction rather than one countywide amount. Yes; new or first-time applicants register with New York State for the STAR credit. Existing STAR exemption recipients generally update registration only for specified ownership/deed changes; beginning in 2026, seniors receiving Basic STAR no longer need to take action to upgrade to Enhanced STAR when eligible. (Source: https://www.tax.ny.gov/pit/property/star/comparison/39-rockland.htm)
• Senior citizens exemption — Homeowners generally age 65 or older who meet local income limits and other ownership/residency requirements; the 2024 NYS exemption report confirms Rockland County assessment rolls included RPTL 467 senior exemptions.. Local governments and school districts may reduce the taxable assessment of the senior’s home by as much as 50%; the local maximum income limit may be set between $3,000 and $50,000, with optional sliding-scale benefits in some localities. Yes; file Form RP-467 for first-time applications and Form RP-467-Rnw for renewals with the local assessor. Apply by Generally March 1 in most communities, but confirm with the local assessor.. (Source: https://www.tax.ny.gov/pit/property/exemption/seniorexempt.htm)
• Veterans exemptions — Eligible veterans or certain family members, depending on the exemption type; New York lists alternative veterans, Cold War veterans, eligible funds, and veterans with a permanent and total disability exemptions, and the 2024 NYS exemption report confirms Rockland assessment rolls included multiple veterans exemption codes.. Alternative veterans exemption may include 15% assessed-value reduction for wartime service, an additional 10% for combat zone service, and an additional disability-related reduction equal to one-half of the service-connected disability rating, subject to local maximums. Cold War veterans exemption benefit is a local-option 10% or 15% exemption, subject to state/local maximums. The permanent-and-total disability veterans exemption, if offered by a taxing jurisdiction, is a full exemption from property taxes, special ad valorem levies, and special assessments. Yes; veterans exemptions are not automatic and require filing the appropriate application with the municipal assessor. Alternative veterans exemption generally only needs to be filed once unless the owner moves or the service-connected disability rating changes; Cold War disability changes may require refiling by taxable status date. Apply by Generally March 1 in most communities, but confirm with the assessor.. (Source: https://www.tax.ny.gov/pit/property/exemption/vetexempt.htm)
• Persons with disabilities and limited incomes exemption — Eligible disabled homeowners using the property as their legal residence, with documented disability and income within locally adopted limits; the 2024 NYS exemption report confirms Rockland County assessment rolls included RPTL 459-c persons with disabilities and limited incomes exemptions.. Up to a 50% reduction in assessed value where the local government or school district has opted in and set income limits; localities may also offer sliding-scale exemptions below 50% for incomes above the basic limit, up to a 5% exemption if income is below $58,400. Yes; first-time applicants file Form RP-459-c, and renewal applicants file Form RP-459-c-Rnw each year unless disability proof already shows the disability is permanent. Apply by Generally on or before the local taxable status date; in most towns this is March 1, but confirm with the assessor.. (Source: https://www.tax.ny.gov/pit/property/exemption/disablexempt.htm)
• Agricultural assessments / agricultural property exemptions — Agricultural property meeting New York agricultural assessment rules; the 2024 NYS exemption report confirms Rockland County assessment rolls included agricultural district and agricultural land not in district exemptions/assessments.. Benefit is based on agricultural assessment values rather than a single countywide dollar amount; NYS publishes annual agricultural assessment values per acre and related agricultural assessment resources. Yes; use the agricultural assessment forms and supporting proof required by the assessor. (Source: https://www.tax.ny.gov/research/property/assess/valuation/agindex.htm)
