Tax Controversies and Litigation

Federal
​​The firm regularly represents taxpayers in civil tax matters before the Internal Revenue Service Examination and Appeals Divisions. Dave Porter represents taxpayers in criminal investigations involving IRS Criminal Investigation (CI), and criminal prosecutions involving the Department of Justice, Tax Division. 
The tax controversy practice includes both domestic and international tax issues.  

The firm performs a great deal of representation involving foreign income and asset compliance issues, including voluntary disclosures (OVDP and Streamlined Procedures), and advice involving FinCEN Report 114
Report of Foreign Bank and Financial Account, and other information reports.

When a tax dispute cannot be resolved at these administrative levels, Dave has litigated disputes before the U.S. Tax Court, U.S. District Courts, the U.S. Court of Federal Claims, and the U.S. Courts of Appeals.

State and Local
The state tax practice focuses on controversy work involving income, employment, and transfer taxes imposed and enforced by California state agencies, including the Franchise Tax Board, State Board of Equalization, Employment Development Department, and Department of Labor. 


The state controversy practice is expected to continue to expand as the State of California becomes increasingly aggressive in its auditing and enforcement activities.
