PROPERTY TAX EXEMPTIONS AND ASSESSMENTS ON PROPERTY:  Your local municipal Assessor establishes the Assessment Value of your Property, reviews and processes eligible property exemptions, assists with the processing of Enhanced STAR and schedules appointments for property tax grievance day.  ALL PROPERTY EXEMPTIONS MUST BE SUBMITTED BY MARCH 1ST EACH YEAR through your local Municipal Assessor (or NYS if related to STAR.)  Grievance Day is usually the 4TH TUESDAY OF MAY EACH YEAR and is filed on NYS Form RP-524.  Further information related to Grievance is available at :NYS Grievance Procedures.  Please contact your local municipality or Assessor and confirm grievance day and time as they are subject to change per municipality.   The Oswego County Assessor Contact List is available hereOSWEGO COUNTY ASSESSOR CONTACT LIST

NYS STAR AND ENHANCED STAR PROGRAMS:  NYS offers STAR and Enhanced STAR options.  The BASIC STAR option is eligible only through NYS at NYS STAR PROGRAM.   The Enhanced STAR is available through NYS or through your local municipal Assessor.  STAR and Enhanced STAR exemption application deadline is March 1st each year.  In the 2020 NYS Budget, it was enacted that BASIC STAR BENEFITS WILL BE DENIED to property owners who are delinquent on their County, Town, Village, City or School property taxes for more than one year.   All delinquent taxpayers who are behind on their property taxes and all delinquent installment contract holders who are behind on their payment schedules must bring their accounts current with the Oswego County Treasurer's Office by MAY 15TH EACH YEAR to keep their STAR exemption or STAR credit.   If you pay your taxes late but pay your taxes in full (becoming current), you may become eligible to get BASIC STAR in the future year.  If you become eligible again, you may be converted from STAR exemption to STAR credit by NYS and then will receive a STAR check.  Once a taxpayer loses their STAR from the school tax bill, the taxpayer can only receive a STAR check with future eligibility.  All inquiries regarding STAR and ENHANCED STAR should be directed to the NYS Department of Taxation and Finance.  Their phone number is 518-457-2036 and their normal office hours are Monday through Friday, 8:30 a.m. – 4:30 p.m. More information may be obtained at:
