Tax Controversy Team of the Year 2015

The Legal 500 US Awards for 2015 recognized Mayer Brown as Team of the Year for Tax Controversy for the second consecutive year. The award honors the best private practice teams over the past 12 months.

Jason Osborn is a Tax partner in the firm’s Washington, DC, office focusing primarily on transfer pricing and other international tax issues. He represents multinational clients in a wide range of industries in negotiations for bilateral advance pricing agreements (APAs) and in transfer pricing controversies. He also provides multinational clients with sophisticated international tax planning services. His transfer pricing experience and insight is extensive and varied and includes cost sharing arrangements, transfers of tangible and intangible property, intercompany services, intercompany loans and guarantees, global dealing and cross-border restructurings. His industry experience includes pharmaceuticals, software, electronics, financial institutions, insurance, automotive, consumer products, energy and transportation, among other industries.

Jason served from 2008 through 2012 in the IRS Office of Associate Chief Counsel (International), most recently as senior technical reviewer in the transfer pricing branch, and before that, as a team leader in the APA Program. In this connection, he provided technical and strategic guidance and advice to the IRS in matters related to transfer pricing, negotiated a significant number of complex APAs, and served as a member of the APA Program’s coordination group for financial institutions. Leveraging his recent government experience, Jason brings to the table a unique and current perspective in advising clients and negotiating APAs and resolutions of transfer pricing controversies.

Prior to joining the IRS, Jason was a Tax associate at Mayer Brown from 2003 to 2008. He began his legal career in 2001 as a tax associate in the New York office of another multinational law firm.

Jason has spoken on panels on current transfer pricing issues hosted by the American Bar Association, the Tax Executives Institute, the Organization for International Investment (OFII) and BNA/CITE.

Mayer Brown was recently named Tax Controversy Team of the Year for the second consecutive year in the Legal 500 United States Awards. "Mayer Brown is 'among the best' and fields a large team…dedicated exclusively to tax controversy and transfer pricing," said Legal 500 and its sources in the US edition. The firm is “regularly seen in the most high-profile controversy cases before the US Tax Court” and produced “yet another impressive run of work” in 2014.
