Litigation and Controversy - Tax

Spinning circle Big letter B

Doug John’s law practice focuses on tax controversy and state and local taxation, with an emphasis on property tax counseling and litigation.

A senior partner in the firm and a Best Lawyers in America honoree, Doug works with individuals and companies to navigate Arizona’s and Nevada’s complex state and local tax systems in order to minimize their income tax, sales and use tax, and property tax liability.

Over the past six years, Doug has reduced his clients’ property tax values by over $2 billion, through a sound knowledge of property tax law, valuation theory and tax assessment practices.

Doug represents clients in all phases of state and local tax litigation, from administrative appeals to court litigation, as well as in appellate matters. He also advises clients on a wide range of state and local tax matters, including multistate income tax issues, nexus issues, and sales and use tax issues.

In the area of property tax, in addition to valuation appeals, Doug represents clients regarding exemptions, tax abatements, tax credits, real property transfer tax, and the real estate tax implications of acquisitions, mergers, development and dispositions, as well as assisting companies with property tax projections.

His state and local clients include individuals and small businesses to Fortune 500 corporations. In property tax matters, his clients represent nearly every segment of the real estate market, including apartments, casinos, department stores, electric cooperatives, golf courses, hotels, industrial warehouses, LIHTC housing, malls, master-planned residential communities, mining operations, office buildings, pipelines, possessory interests, residential developments, senior care/assisted living facilities, and shopping centers.
