Who Audits Benefit Plans

Global and national audit firms continue to dominate the ERISA benefit plan marketplace. With nearly 2,400 clients, CliftonLarsonAllen audits the most number of ERISA benefit plans in the U.S.  RSM US, a close second, audits almost 2,300 benefit plans.

While the Big Four may not audit the most number of plans, they do play a significant role in auditing the larger ERISA benefit plans.

Only one Big Four firm was named in the top ten by the number of plans audited, but each of the Big Four firms lead in terms of total plan assets. With over $1 trillion in assets audited, PricewaterhouseCoopers leads the top ten. KPMG, Deloitte, and Ernst & Young each follow with between $760 and $886 billion in assets audited. Together, the Big Four audit 41% of the total market.

This data is based off of 2016 filing year, with a filing deadline of October 15, 2017.
