Donna McComber, a highly regarded transfer pricing economist with the Internal Revenue Service, has rejoined Baker McKenzie as a Director of Economics.


Based in Washington, DC, Ms. McComber spent the last 10 years with the IRS, most recently serving as Assistant Director of the agency's Advance Pricing and Mutual Agreement Program. Prior to joining the IRS in 2006, Ms. McComber was a Senior Economist with Baker McKenzie.


At the IRS, Ms. McComber was involved in some of the most difficult cases in APMA’s inventory, including intangibles migration, restructuring, and financial product cases. In addition to making strategic and policy decisions involving procedural and technical issues, Ms. McComber also reviewed numerous Advance Pricing Agreements and Mutual Agreements for a range of treaty partners.


In addition, McComber led competent authority negotiations with China, Denmark, Germany, Japan, Mexico, Switzerland and the United Kingdom, and was a critical contributor to negotiations with other treaty partners, including Australia, Canada, and Korea. 


"Donna is well known in the transfer pricing community and brings a wealth of knowledge from the government side in negotiating APAs and resolving MAP issues, two procedures that are highly important to companies engaging in cross-border transactions with related parties," said Tom Linguanti, Chair of the Firm's North American Tax Practice. "In addition, Donna's insights into the perspectives of numerous US treaty partners will immediately benefit our clients. We are very pleased to have her back on the team."


In her role with the IRS, Ms. McComber developed a focus on discount rates and cost-sharing, playing a critical role in drafting the IRS's cost-sharing regulations. She also assisted the IRS Chief Counsel in reviewing appeals and audit cases for specific issues, including pre-tax/post-tax issues, discount rate issues and useful life issues.


"Many of our clients seek insights on the complexities of the cost-sharing regulations for the purposes of both planning and compliance, and Donna's unique experience with the IRS in developing these rules will further strengthen and deepen our transfer pricing, regulatory, and controversy capabilities," added Mr. Linguanti. 


With 950 tax practitioners in more than 40 countries, Baker McKenzie's Tax Practice is one of the most highly-rated and recommended among law firms worldwide. The practice provides a strong network of tax professionals offering domestic and multinational companies with a full complement of tax planning services, from analysis to implementation, as well as a full range of tax dispute resolution services in the US and abroad, including advice on US and global tax policy, transfer pricing, customs, local and indirect tax and employee benefits tax issues.


The US tax practice was recently recognized by Law360 in its 2015 "Tax Practice Groups of the Year" and by US News & World Report and Best Lawyers as a National Tier One firm for tax law. The Firm was also named Americas Tax Disputes Firm of the Year for 2015 by the International Tax Review.


Ms. McComber is the latest in a series of prominent hires for the Tax Practice in North America. Experienced trust and estates attorney David Berek recently joined in Chicago, and tax planning attorneys Jennifer Molnar, Patrick Cox and Dan Cullen recently joined Washington, DC, New York and Chicago, respectively.


Baker McKenzie's global team of economists consists of more than 30 practitioners based in North America, and over 50 worldwide.  It is the only law firm to compete with the Big 4 and one of the very few law firms to offer integrated legal and economics transfer pricing services.  Baker & McKenzie LLC provides economic, quantitative, financial engineering and valuation services in connection with a wide range of client needs.


"I am thrilled to rejoin Baker McKenzie," said Ms. McComber. "I look forward to working with its highly regarded team and utilizing my government experience to provide strategic tax guidance to our clients on critical transfer pricing matters."


Ms. McComber received her B.A. from the University of Mary Washington and her M. A. in Economics from Vanderbilt University.


Concluded Rick Hammett, Baker McKenzie's North American Managing Partner, "We are focused on further strengthening our Firm's capabilities across North America. Donna's previous experience at our Firm, combined with her work at the IRS, will be highly valuable to our clients."
