Employee Benefit Plan Audits

To file an annual return/report, the Employee Retirement Income Security Act (ERISA) requires employee benefit plans with 100 or more participants to undergo an audit by a qualified, independent public accountant. Employee benefits plan audits help protect your assets and the financial integrity of the plan, as well as ensure the necessary funds will be available to pay retirement, health, and other promised benefits to your employees.

The RPB Difference: 100 Plan Audits Performed Every Year

One of the most common complaints targeting CPA firms is their inability to test in areas unique to employee benefit plans. As the oldest registered accounting firm in Wisconsin, RPB has performed thousands of employee benefit plan audits, placing us in the top 5% of firms nationally. It is a frequent part of our work.


“We needed our 401K plan audited. Our accountants recommended RPB, as did our Third Party Administrator. RPB turned out to be fantastic—they ask for what they need and do the rest behind the scenes. We’ve used only them for our audits and are very happy—they’ve been our partner since 2011. They are fast, efficient, and friendly.”
