Five ways strong internal controls can help reduce employee benefit plan audit fees

Organizations that invest in effective internal controls often spend less time resolving audit issues and may reduce the cost of an employee benefit plan audit. Controls over payroll, eligibility, contributions, participant data, and plan documentation should be performed throughout the year to identify and correct errors before audit fieldwork begins. For HR, payroll, and finance teams, effective internal controls support a more efficient audit process and more predictable audit fees.

A practical framework: control, document, review, remediate

Plan sponsors can improve audit readiness by implementing this four-part framework: 

• Control: Establish processes that address key risks.
• Document: Maintain evidence that required procedures were completed.
• Review: Identify exceptions and address them promptly. 
• Remediate: Correct issues before they become audit findings. 

Applying the control-document-review-remediate framework across key plan processes throughout the year creates tangible benefits during the audit. The examples below illustrate how strong internal controls can improve audit efficiency, reduce the time auditors spend resolving issues, and help manage audit costs.

1. Fewer errors can reduce audit testing.
   
   Effective controls over payroll, participant data, eligibility, and contributions help identify and correct errors before they affect the audit. For example, a monthly comparison of payroll census data to the recordkeeper’s participant listing can identify missing new hires, terminated employees who remain active, or compensation fields that don’t align with the plan document. Correcting issues before the audit gives auditors fewer exceptions to investigate, letting them focus testing on higher-risk areas. Less time spent resolving errors and explaining variances can translate into less audit effort and more predictable fees.
   
2. Strong documentation reduces follow-up questions.
   
   Auditors rely heavily on documentation, including plan provisions, payroll reports, contribution calculations, census data, and remittance support. They also need evidence of management review. A smooth audit often comes down to whether supporting documentation is complete, easy to reconcile, and available when needed. An audit-ready folder organized by request category keeps information readily available. It also reduces follow-up questions, and prevents teams from recreating documentation under deadline pressure. The result is fewer requests, less back-and-forth communication, and fewer billable hours spent on clarification.
   
3. Effective controls support reliance on system processes.
   
   When key processes are controlled and reviewed, auditors may rely more on system-generated reports and consistent procedures. These processes include payroll calculations, eligibility determinations, contribution remittances, and loan or distribution activity. This is especially important when plans use third-party recordkeepers or payroll providers. Plan management remains responsible for understanding the reports used to administer the plan and retaining evidence that key outputs were reviewed. Greater reliance on tested and automated processes can decrease the extent of manual audit work.
   
4. Improved timeliness helps manage costs.
   
   Late or incomplete information is one of the most common drivers of increased audit fees. Organizations with strong internal controls typically provide reliable data more efficiently because reconciliations, approvals, and exception reviews are built into their monthly or quarterly close process. Plan sponsors that prepare core audit support before fieldwork begins may be able to reduce avoidable follow-up requests, saving time for both management and auditors. The result is a smoother audit timeline, fewer deadline-driven requests, and more predictable costs.
   
5. Strong controls reduce the risk of compliance findings.
   
   Employee benefit plans are subject to strict regulatory requirements. Effective controls over participant loans, hardship withdrawals, compensation definitions, eligibility, forfeitures, and contribution timing help prevent compliance issues that require additional audit procedures. For example, if the plan document excludes bonuses or certain fringe benefits, payroll teams should confirm that contribution calculations consistently apply the correct definition of compensation throughout the year — not after an auditor identifies a discrepancy. Fewer compliance exceptions to investigate means less time billed to the audit and fewer surprises for plan management.

How to put this into action

• Assign ownership of each key control across HR, payroll, finance, and, if applicable, plan administration.
• Create a recurring calendar for census reviews, contribution reconciliations, remittance checks, and documentation updates.
• Maintain an audit-ready folder containing final reports, reconciliations, approvals, and evidence of management review.
• Review prior-year audit requests and findings to identify recurring issues and opportunities for improvement.
• Meet with the auditor before year-end to confirm timing, data needs, and any plan changes that could affect testing.

What’s next

For organizations sponsoring employee benefit plans, investing in strong internal controls is a cost-effective strategy. The best results usually come from controls that are practical, repeatable, and owned by the teams closest to the data. HR, payroll, and finance all play a role in maintaining accurate participant information, timely contribution processes, documented reviews, and clear audit support. A stronger control environment reduces the time auditors spend resolving exceptions and creates greater opportunities to reduce audit fees while improving plan compliance and operational efficiency.
