Michelle DeLappe

Michelle helps businesses reduce their state and local tax exposure through effective planning, defending against assessments and pursuing refunds.

Admitted in Washington, Oregon, Idaho, Montana, and Alaska, she handles state and local tax matters in a variety of contexts, including strategic planning, transactions, audits, administrative appeals and litigation. Her experience includes litigating some of the largest property tax disputes in Washington state history. She also helps businesses navigate issues involving nexus, apportionment, sales and use tax, B&O tax, real estate transfer taxes and other excise taxes and fees.

Michelle also represents clients in rate cases and other proceedings before the Washington Utilities and Transportation Commission (UTC). Her experience with administrative law, financial analysis and regulated industries in her state and local tax practice enables her to successfully advocate for clients in UTC proceedings.

A frequent contributor to the discussion on state and local taxes in the Pacific Northwest, Michelle has written for Tax Notes State (a Tax Analysts publication) and co-authors the Washington and Alaska chapters of the ABA Property Tax Deskbook. She regularly presents at events around the country, such as conferences hosted by the Council on State Taxation, Institute for Professionals in Taxation, American Bar Association, Seattle Chapter of the Appraisal Institute and the NYU Institute on State and Local Taxation.
