With a focus on high-net-worth individuals, Dennis advises on wealth transfer planning and compliance, optimization of pooled family investment structures, income tax planning around major liquidity events and state tax minimization for trusts. In the corporate context, he works with clients to plan, design and implement accounting and inventory methods, capitalization structures, holding company structures designed to minimize tax burden, various entity structures, and federal and state tax credit studies. Dennis has worked extensively with both inbound and outbound corporate structures and has significant experience with consolidated tax returns and multi-state reporting. He serves clients spanning several industries, including manufacturing, wholesale and distribution, retail and real estate.
