Frequently Asked Questions

What is a benefits audit?

A benefits audit is a comprehensive review of an organization's employee benefits programs to verify accurate administration, regulatory compliance, and cost effectiveness. It examines plan documents, eligibility practices, enrollment accuracy, premium calculations, vendor performance, and compliance with laws like ERISA and ACA. Regular benefits audits protect both the organization's fiduciary obligations and employees' access to the benefits they have been promised.

How often should a benefits audit be conducted?

Conduct a comprehensive benefits audit annually, ideally three to four months before your plan renewal date to inform negotiation strategies. Targeted audits of high-risk areas like ACA compliance and dependent eligibility should be performed more frequently, at least semi-annually. Additional audits are warranted when changing vendors, implementing new plans, or after significant regulatory changes.

What is a dependent eligibility audit?

A dependent eligibility audit verifies that all dependents enrolled in employee benefit plans meet the plan's eligibility requirements. It typically involves requesting documentation such as marriage certificates, birth certificates, or adoption papers from employees to confirm dependent relationships. These audits commonly identify 5 to 10 percent of enrolled dependents as ineligible, resulting in significant cost savings for the organization.

What ACA compliance areas should be audited?

Audit ACA compliance by verifying that applicable large employer status is correctly determined, measurement periods for variable-hour employees are properly tracked, and offers of coverage meet minimum value and affordability standards. Review Forms 1095-C for accuracy before distribution and confirm that all required ACA reporting has been filed correctly and on time. Check that waiting periods do not exceed 90 days for eligible employees.

How do you reconcile benefits carrier invoices?

Compare carrier invoices line by line against your enrollment records to verify that every enrolled employee and dependent appears correctly and that terminated employees have been removed. Validate premium rates against your plan agreements and check for any unauthorized changes. Document discrepancies and work with carriers to resolve billing errors, which commonly amount to 2 to 5 percent of total premiums.

What ERISA compliance should be verified in a benefits audit?

Verify that summary plan descriptions are current and have been distributed to participants, plan documents are properly executed and consistent with actual administration, and Form 5500 filings are accurate and timely. Review fiduciary processes for any plans with employer-directed investments and confirm that all required participant notices have been provided within mandated timeframes. Check that claims and appeals procedures comply with ERISA requirements.

How do you audit COBRA administration?

Review COBRA qualifying events over the audit period to verify that election notices were sent within the required 14-day timeframe after the plan administrator is notified. Confirm that qualified beneficiaries were offered the correct continuation coverage at the appropriate premium, and that coverage termination dates are properly calculated. Verify that any premium assistance or subsidy programs were correctly applied during the audit period.

What should you do with benefits audit findings?

Categorize findings by severity and create a remediation plan with specific actions, responsible parties, and deadlines. Address compliance violations immediately to minimize legal exposure and potential penalties. Use findings to improve ongoing administration processes, renegotiate vendor agreements, and inform benefits strategy decisions for the upcoming plan year.
