Ellyn B. Tanenberg, Attorney & CPA

Ellyn B. Tanenberg brings a unique combination of legal and accounting expertise to property tax consulting in Washington D.C. As both an attorney and CPA, she understands property valuation from multiple perspectives and can identify assessment errors that others might miss. Our practice focuses on personalized service for property owners who want direct access to experienced professionals rather than junior staff. We handle each case with attention to detail that comes from decades of experience in tax law and property valuation. Every client works directly with our principal attorney, ensuring consistency and expertise throughout the appeal process.

Our comprehensive property tax services include detailed assessment reviews that examine both the technical accuracy of valuations and their compliance with D.C. tax law. We specialize in residential tax protests for homeowners facing unexpected assessment increases, providing thorough analysis of comparable sales and property-specific factors that may support lower valuations. For commercial properties, we offer sophisticated valuation analysis using income, cost, and market approaches appropriate to each property type. Our accounting background allows us to prepare detailed income and expense analyses that support alternative valuations for rental properties and commercial buildings. We also provide ongoing tax planning services to help property owners understand assessment cycles, plan for major improvements, and take advantage of available tax relief programs throughout D.C.

Every engagement begins with a comprehensive consultation where we review your property records, assessment history, and specific circumstances. We provide honest assessment of your case's strengths and potential savings, along with estimated costs and timelines for different approaches. If we proceed with an appeal, we conduct thorough market research, prepare detailed valuation analyses, and gather supporting documentation. Throughout the process, you work directly with our principal attorney rather than being handed off to junior staff. We handle all aspects of the appeal process while keeping you informed of developments and strategic decisions.

We serve property owners throughout Washington D.C. and have particular expertise with properties in established neighborhoods like Georgetown, Dupont Circle, and Capitol Hill where unique characteristics and historic designations can complicate assessments. We also assist clients with properties in Montgomery and Prince George's Counties.
