Avoid auditors offering unusually low fees or lacking dedicated benefit plan experience, those are serious red flags. Ask about annual audit volume, peer review results, and who’ll actually perform your audit. Keep going to uncover everything you need to make a confident, informed decision.
What Qualifications Should a Benefit Plan Audit Firm Actually Have?
When selecting an audit firm for your employee benefit plan, you’ll want to verify that they hold a valid CPA license and maintain membership in the American Institute of Certified Public Accountants (AICPA).
Beyond these basics, confirm that the firm participates in the AICPA‘s Employee Benefit Plan Audit Quality Center (EBPAQC). Membership signals a commitment to specialized training and rigorous quality standards specific to benefit plan audits.
You should also check whether their professionals hold relevant credentials, such as the Certified Employee Benefit Specialist (CEBS) designation, which demonstrates deeper expertise in employee benefits administration and regulatory compliance.
Red Flags That Signal a Low-Quality Benefit Plan Auditor
Spotting a low-quality benefit plan auditor early can save you from costly compliance failures and potential DOL penalties.
Watch for auditors offering unusually low fees, since deep discounts often signal limited ERISA experience or rushed work.
Be cautious if they can’t demonstrate dedicated employee benefit plan audit volume or relevant peer review results.
Avoid firms that assign inexperienced staff without proper supervision or skip essential audit procedures to cut time.
If an auditor seems unfamiliar with Form 5500 requirements or avoids discussing their DOL inspection history, treat that as a serious warning sign worth investigating further.
How Much Does a Benefit Plan Audit Cost in 2026?
Once you’ve filtered out low-quality auditors, your next practical question is what a legitimate benefit plan audit will actually cost you in 2026.
Fees typically range from $8,000 to $30,000, depending on plan complexity, participant count, and transaction volume. Larger plans with multiple investment options or international components push costs higher.
Don’t automatically choose the cheapest bid—suspiciously low quotes often signal cut-corner work that triggers DOL scrutiny.
Request itemized proposals from at least three qualified firms so you’re comparing equivalent scope.
Treat the audit as a compliance investment, not simply an expense to minimize.
Big Firm or Local CPA: Which Is Right for Your Plan Audit?
Choosing between a large national firm and a local CPA practice isn’t simply a matter of prestige or price—it comes down to experience, availability, and fit with your plan’s specific needs.
Large firms bring deep specialization and dedicated benefit plan audit teams, which matters if your plan is complex or large.
Local CPAs often provide more personalized attention and competitive pricing, but verify they perform enough benefit plan audits annually to stay current with DOL requirements and ERISA regulations.
Whichever you choose, confirm the firm holds an AICPA Employee Benefit Plan Audit Quality Center membership—that credential signals genuine commitment to this specialized work.
What Should You Ask a Benefit Plan Auditor Before Hiring?
Before you sign an engagement letter, arm yourself with the right questions—what you ask a prospective auditor reveals as much about their qualifications as any credential on their website.
Ask how many employee benefit plan audits they complete annually and what percentage of their practice that represents.
Find out if they’ve handled plans similar to yours in size and type.
Ask about their peer review results, recent DOL audit experience, and staff turnover.
Confirm who’ll actually perform the work—not just who’ll sign the report.
Their answers will quickly separate genuinely qualified firms from those simply willing to take your engagement.
