Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Sullivan County Real Property Tax Services Agency.
Relief programs
The filing guidance for this county is: March 1, 2026 taxable-status date for most New York exemption applications; confirm with the local assessor. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationNew York senior-citizen exemption (RPTL §467) is locally adopted; qualifying owners are generally age 65+ and subject to the income limit set by the county, city, town, village, or school district, with up to a 50% assessed-value reduction. Basic and Enhanced STAR provide school-tax relief; new applicants register for the STAR credit with NYS, while Enhanced STAR is for eligible owners age 65+ subject to the current income limit. Confirm the local scale with the municipal assessor.
No general countywide assessed-value cap verified. New York requires annual assessment at a uniform percentage of market value; the New York property-tax cap limits annual tax-levy growth (generally 2% or inflation, with exceptions), not an individual parcel's assessed value.
Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: 2026 assessment complaints are filed with the applicable municipal Board of Assessment Review by that municipality's Grievance Day; countywide date not published. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
