EY hires Koch as new Americas tax policy chief

Harry Reid, the Democrats' leader in the US Senate, has lost his chief adviser on tax and economic policy to EY.

Cathleen Koch is to join EY as Americas tax policy leader, where she will be responsible for developing the Big 4 firm's capabilities on the subject in more than 30 countries in the Americas. She will also advise clients on US, Americas and global tax policy matters.


Koch has worked on almost every Congressional tax and budget measure since January 2013, when she joined Senator Harry Reid's staff. Before this she was tax chief at the Senate Finance Committee, where she led the work on legislation such as the Troubled Asset Relief Programme, the American Recovery and  Reinvestment Act and the Affordable Care Act. She was also senior tax policy adviser and staff director of the Finance Subcommittee on Energy, Natural Resources and Infrastructure.


Koch was director of tax policy and senior tax adviser for General Electric, the industrial and financial services group, and director of global government affairs for Amgen, the biotechnology company.
