Diann Smith focuses her practice on state and local taxation and unclaimed property advocacy. Diann advises clients at any stage of an issue, including planning, compliance, controversy, financial statement issues and legislative activity. Her goal is to find the most effective method to achieve a client's objective regardless of when or how an issue arises. Diann emphasizes the importance of defining a client's objective - whether it is finality of a frequently audited issue, quick resolution of a stand-alone tax liability, or avoiding competitive disadvantages in the application of a tax. The defined objective then governs the choice of the path to a solution.
Her clients span a broad range of industries, including transportation, retail, government contractors, information services, emerging technologies, financial services, health care, digital and cloud computing services, and oil and gas. Diann has represented clients on nexus, tax base, business/non-business income classification, apportionment and ASC 740-10 compliance issues. She has also counseled clients on multi-state unclaimed property compliance and voluntary disclosure opportunities, and has contributed as a co-author for a cert petition filed before the US Supreme Court. She serves as outside counsel on state tax and unclaimed property matters for the Entertainment Software Association and the National Retail Federation.
