Property Tax Grievances in St. Lawrence County, New York
St. Lawrence County publishes grievance tools, the RP-524 form, completion guidance, SCAR information, and an annual municipality-by-municipality Grievance Day schedule. Filing still occurs with the city, town, or assessing village responsible for the roll. The ordinary 2026 windows have passed. The FairPath owner-guided packet remains available year-round to organize official records, owner-approved corrections, comparisons, condition evidence, calculations, and source notes. FairPath does not file RP-524, choose the homeowner's value or requested assessment, contact the assessor or Board, represent the owner, or predict an assessment change, tax savings, tax bill, or outcome.
Assessment context: Begin with the current municipal assessment roll and identify SWIS code, parcel, class, exemptions, assessed value, uniform percentage, valuation date, and inventory facts. St. Lawrence County Real Property publishes assessment rolls, sales reports, equalization rates, tax maps, assessor contacts, and a Beacon portal. The county spans Ogdensburg, Canton, Potsdam, Massena, Gouverneur, villages, farms, forest and recreational acreage, St. Lawrence River property, Adirondack-influenced areas, manufactured housing, wells, and septic systems. These markets and assessing units are not interchangeable. River access, seasonal use, agricultural or forest status, acreage utility, mineral or commercial influence, and municipal services must be verified rather than inferred from proximity.
Filing process: New York generally uses Form RP-524 for this local Board of Assessment Review process. Use the county's annual grievance schedule and assessor directory to identify the exact assessing unit, then confirm tentative-roll publication, assessor sitting dates, Board date and hours, filing address, copies, appointment procedure, and receipt method. A city or assessing village may diverge from the ordinary fourth-Tuesday pattern. The homeowner supplies the grounds, value estimate, requested assessment, facts, and signature. Preserve the complete form, roll page, proof of delivery, exhibits, and Board determination. SCAR eligibility and Article 7 review begin only after the administrative route and have separate fees and deadlines; FairPath does not select or file a later proceeding.
Evidence to review: Anchor the packet to the subject's municipal roll and property record. Document measurable errors in acreage, waterfront or access, living area, units, property class, agricultural or forest status, outbuildings, utilities, basement, additions, and exemptions. Select sales or assessment records from the same assessing unit and relevant submarket, then explain differences in river or lake influence, village services, farm use, timber or recreational land, seasonal access, wells, septic, effective age, renovation, and condition. Apply the correct local equalization or uniform percentage before comparing assessments across municipalities. Dated photographs, surveys, permits, inspections, appraisals, farm records, and contractor scopes can establish facts. Repair cost is not an automatic dollar-for-dollar value adjustment. Owner facts remain attributed and homeowner-approved.
Current deadline guidance: 2026 municipal grievance windows are closed; verify the 2027 county schedule and local notice. St. Lawrence County publishes a dedicated annual list of Grievance Day dates because cities, towns, and assessing villages can use different dates and hours. The responsible assessing unit's 2026 entry and receipt instructions controlled; no generic countywide date is substituted.
St. Lawrence County publishes an annual municipality-specific grievance schedule rather than presenting one countywide date. Save the exact schedule entry, tentative-roll page, assessing-unit name, Board hours, and retrieval date together because the schedule can change each cycle.
Ogdensburg, towns, and assessing villages can have different calendars, offices, ratios, and Board hours.
St. Lawrence River frontage, Adirondack influence, farms, forest acreage, seasonal property, manufactured homes, wells, and septic systems require specific controls.
Use the county's roll, sales, equalization, tax-map, and assessor resources together while preserving each record's assessing-unit identity.
