Delivering Exceptional Tax Strategy Across New York
Across New Yorkʼs 62 counties, Ryan applies local insight, data analytics, and statutory expertise to identify overassessments, manage exposure, and secure sustainable savings for commercial portfolios.
New York County
As the stateʼs financial core, Manhattan presents dense commercial concentration, constant redevelopment, and high-value real estate turnover. Complex valuation models, driven by income, rent rolls, and capitalization rates, require technical precision and consistent monitoring.
Business Property Classification: Real property is assessed at market value under the New York City Department of Finance (DOF) guidelines, and personal property is exempt.
Local Millage Rates: Property class–based rates (commercial, residential, utility) are set annually by the NYC Council.
Strategic Considerations: Commercial properties are subject to class-based caps. Annual DOF tentative roll reviews are crucial for capturing appeal opportunities.
Erie County
Buffaloʼs revitalized industrial and logistics economy drives steady assessment growth across warehousing, light manufacturing, and redevelopment projects. Frequent revaluations and special-district overlays create exposure for businesses with expanding portfolios.
Business Property Classification: Real property is subject to local assessment, and tangible personal property is exempt.
Local Millage Rates: Countywide rates average 2.65% of market value and vary by municipality and school district.
Strategic Considerations: Rapid redevelopment and shifting industrial baselines make periodic ratio verification essential to prevent inflated assessments.
Westchester County
Westchesterʼs proximity to New York City and its concentration of corporate offices and mixed-use developments generate premium valuations and complex apportionment across municipalities. Precise management of exemptions and special assessments is key.
Business Property Classification: Real property is assessed locally, and personal property is not taxable.
Local Millage Rates: The average combined effective tax rate ranges from 2.5 to 3.0%, depending on school and town levies.
Strategic Considerations: High-value office and multifamily conversions introduce opportunities for reassessment requests and valuation relief after renovation.
Albany County
As New York’s capital region, Albany County combines government operations, higher education, and growing technology sectors with steady commercial development. Assessment uniformity and transparency initiatives have modernized valuation practices, but rising property values continue to drive scrutiny of assessments for office, retail, and mixed-use properties.
Business Property Classification: Real property is assessed at full market value, and tangible personal property is exempt from taxation.
Local Millage Rates: The average combined effective rate is approximately 2.7%, with variations across municipal and school district boundaries.
Strategic Considerations: Frequent revaluation cycles and public-sector ownership concentrations require proactive coordination with assessors and timely filing of appeals to maintain fair assessments.
Monroe County
Anchored by Rochester, Monroe County features a diverse economy spanning healthcare, optics, education, and advanced manufacturing. Ongoing revitalization in downtown and riverfront areas, combined with adaptive reuse of industrial properties, drives frequent reassessment and classification adjustments.
Business Property Classification: Real property is assessed locally at full market value, and tangible personal property is exempt.
Local Millage Rates: Average effective tax rates range from 2.6 to 3.1%, depending on local municipal and school levies.
Strategic Considerations: Redevelopment projects and tax increment financing (TIF) zones can significantly alter valuation baselines, making early engagement and consistent audit reviews essential to identify and correct overassessments.
Onondaga County
Centered around Syracuse, Onondaga County serves as a major economic and logistics hub in Central New York, with strong ties to higher education, healthcare, and manufacturing. Ongoing infrastructure investments and redevelopment of industrial and waterfront districts have contributed to increasing property values and heightened scrutiny of commercial assessments.
Business Property Classification: Real property is assessed locally based on market value, and tangible personal property is generally exempt from taxation under New York State law.
Local Millage Rates: Effective property tax rates across the county’s municipalities and school districts typically range from 2.6% to 3.4% of market value, depending on local levies.
Strategic Considerations: Varying assessment levels and equalization rates across towns and the City of Syracuse require ongoing monitoring to ensure fair valuations. Active redevelopment and infrastructure investment can trigger shifts in commercial assessments, making coordination with assessors and timely appeals essential to maintain equitable tax positions.
