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 Onondaga County Real Property Tax Services.
Relief programs
The filing guidance for this county is: March 1, 2026 for county properties outside Syracuse, as stated by Onondaga County RPTS; file local exemption applications with the applicable town or city 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's 2026 Enhanced STAR benefit is for a qualifying owner-occupied primary residence with at least one resident owner age 65 or older by December 31 and combined income of resident owners and spouses of $110,750 or less. A municipality may also grant the senior-citizens exemption under RPTL §467, reducing assessed value by up to 50% subject to its local income limit; file RP-467 or RP-467-Rnw with the local assessor, usually by March 1.
New York's property-tax cap limits the annual levy of participating local governments and most school districts to the lower of 2% or inflation, with override provisions; it is not an individual parcel assessed-value cap. Local assessors apply uniform-assessment rules under New York Real Property Tax Law.
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: May 26, 2026 is the standard fourth-Tuesday-in-May New York Board of Assessment Review grievance day; Onondaga County has no countywide assessor and local town/city assessors control any alternate date. File RP-524 locally. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
