Otto Bosch

My practice focuses on federal, state, and international tax matters, with an emphasis on tax controversy, complex pass-through entity taxation, and high-net-worth taxpayer issues. I advise clients through all stages of tax disputes, from audit strategy and information development to administrative resolution, helping individuals and businesses navigate examinations, proposed adjustments, and compliance challenges while balancing litigation risk and practical business outcomes. Drawing on experience within both government and private practice environments, I provide strategic guidance on partnership and S-corporation taxation, related-party transactions, and technical issues frequently arising in sophisticated investment and operating structures.

I regularly counsel clients on multi-jurisdictional tax matters, including state and local tax compliance, conformity issues, and the tax implications of mergers, acquisitions, and other business transactions. My work includes drafting technical analyses, memoranda, and responses to taxing authorities, as well as advising on controversy procedures, penalties, and regulatory developments affecting complex taxpayers. I also assist in transactional diligence and risk assessment, helping clients anticipate and mitigate exposure before disputes arise.

In addition, my practice has included tax research and regulatory analysis involving some international and cross-border considerations, enterprise-level compliance reviews, and nonprofit and employee benefit plan matters. I bring a practical, solutions-oriented approach shaped by experience coordinating with auditors, counsel, and stakeholders, enabling clients to resolve disputes efficiently while maintaining long-term compliance and strategic tax positions.
