Spencer Fane LLP is pleased to welcome David S. Barnhill to the firm’s Tampa office as a partner in the Tax, Trusts, & Estates practice group.

David represents corporate clients in international tax planning initiatives, including inbound and outbound restructuring, and diligently guides high-net-worth individuals through pre-residency planning, expatriation, and other international tax and succession planning matters. Notably, he has advised numerous clients on participation in the IRS Offshore Voluntary Disclosure Program and other U.S. international income tax and reporting compliance matters.

In addition to maximizing clients’ tax benefits, David’s practice focuses on resolving the many complex stages of tax controversy disputes, where his representation experience spans IRS examinations and appeals, U.S. Tax Court proceedings, and federal appellate litigation.
