Selected Experience

Sutherland client prevails in PK Ventures, Inc. v. Commissioner appeal.
Sutherland was retained to seek reconsideration and file an appeal in connection with many different issues that the taxpayer had lost at trial when represented by other counsel. We determined that the IRS, prior counsel and the U.S. Tax Court mischaracterized many of the issues under TEFRA, causing the Tax Court to agree with us that it lacked jurisdiction to sustain many of the IRS adjustments, and (after prompting from the U.S. Court of Appeals for the Eleventh Circuit) that most of the remaining IRS adjustments were time-barred under TEFRA. As a result, our client prevailed on most of the IRS’ adjustments.
Sutherland represents international insurance company in tax litigation regarding $306 million tax refund.
Sutherland represents an international insurance company in a refund suit that it filed for its 1997 tax year, seeking the return of approximately $306 million in tax, penalties and interest. The case involves a number of issues, including whether the company is entitled to certain foreign tax credits that it claimed in various cross-border financing transactions.
Sutherland obtains ruling invalidating IRS’ penalties in “Son of Boss” case.
Sutherland represented a partnership in one of the first of the so-called “Son of Boss” cases to go to trial. We obtained one of the very few rulings in these cases invalidating the IRS’ assertion of penalties and then successfully defended the ruling on appeal in the Fifth Circuit.
