Greenspoon Marder

Greenspoon Marder brings decades of property tax expertise to Denver's complex assessment landscape. Our team understands that property taxes represent one of your largest ongoing expenses, whether you're a commercial property owner, residential investor, or homeowner facing an unexpected assessment increase. We've built our reputation on thorough analysis and aggressive advocacy. Our attorneys don't just file appeals—we dig deep into valuation methodologies, market comparisons, and assessment procedures to build compelling cases. With extensive experience in Colorado's property tax system, we know how assessors think and what evidence carries weight in hearings.

Our comprehensive property tax services start with detailed assessment reviews where we analyze your property's classification, valuation methods, and comparable sales data. We identify discrepancies in square footage, condition ratings, or inappropriate comparisons that often lead to overassessments. Our formal appeal process includes preparing and filing all necessary documentation with county assessors and boards of equalization. We handle residential appeals for homeowners dealing with sudden increases and complex commercial appeals involving income capitalization and cost approaches. Our valuation dispute services extend beyond appeals to include consultation on property improvements, exemption applications, and strategic timing for major renovations. We also provide ongoing monitoring services, tracking your assessments year over year and proactively identifying issues before they become costly problems. For investors and developers, we offer portfolio reviews to ensure consistent and fair treatment across multiple properties.

Our process begins with a comprehensive property analysis, typically completed within 48 hours of engagement. We review three years of assessment history, recent sales data, and property characteristics to identify grounds for appeal. Next, we conduct market research and may arrange for independent appraisals when beneficial. We prepare detailed appeals addressing specific valuation errors and file within statutory deadlines. Throughout the hearing process, we present evidence methodically, cross-examine assessor witnesses, and negotiate settlements when appropriate. Most cases resolve within 90-120 days, though complex commercial properties may require longer timelines.

We serve the entire Denver metropolitan area including Jefferson, Adams, Arapahoe, Douglas, and Boulder counties. Our team regularly appears before assessment boards throughout the Front Range and maintains relationships with assessors' offices across the region. We also handle select high-value properties statewide when the economics justify our involvement.
