Choosing an audit firm in Iowa

Engagement volume is the most objective public signal of employee benefit plan audit experience: the Department of Labor’s audit quality study found deficiency rates of 76% among CPAs performing one or two plan audits a year, versus 12% at the largest practices. The table above shows which firms do this work in Iowa at real volume.

Beyond volume, ask candidate firms about AICPA Employee Benefit Plan Audit Quality Center membership, who staffs the fieldwork, experience with your recordkeeper and payroll systems, and whether the fee assumes an ERISA Section 103(a)(3)(C) election. A Iowa address is not required — plan audits are performed remotely under the same national standards — but local presence can simplify scheduling and walkthroughs.
