Nicknamed “the professor” by his colleagues, Tim Riffle offered nearly encyclopedic knowledge of federal tax law. With more than three decades of practice advising on the tax challenges associated with all phases of the business life cycle, Tim guided clients through complex tax matters, providing solutions that help maximize tax savings while minimizing the potential for controversy.
Tim’s business clients ranged from Fortune 500 companies to startup ventures, including middle market companies, multistate and multinational companies, privately held and family businesses, investment funds, closely held S corporations, LLCs and partnerships, start-ups, entrepreneurs and high net worth individuals. Tim offered extensive experience in the tax implications of structuring business combinations, new business formations, pass-through entities (partnerships, S corporations, and LLCs) and tax exempt organizations.
Tim also represented individuals and families in the areas of charitable giving, foundations and gift and estate taxation, and universities, hospitals, museums and other non-profit organizations in tax exemption and unrelated business income tax matters. In addition, he advised fiduciaries and beneficiaries involved in probate, guardianship and trust administration matters.
Dedicated to consistently delivering clear, concise and practical tax counsel, Tim guided clients through complicated federal and state tax laws and regulations with the goal of helping them to achieve their overall objectives. He was appreciated by clients and colleagues alike for prompt and efficient tax advice that actually parallels and enhanced their financial goals, and was committed to structuring transactions and resolving matters with solutions that ensure tax efficiencies.
Notably, Tim was co-author of the Indiana Limited Liability Company Forms and Practice Manual (Data Trace Publishing, 1996).
Tim spent his entire career in private practice at Barnes & Thornburg, beginning as an associate in 1983. A resident of Bloomington, Indiana, Tim has two children, Madeline, a researcher at a Fortune 500 corporation, and Mark, a lawyer.
