Pension Plan Compliance Under ERISA

A defined benefit (DB) plan — also called a pension plan — promises participants a specific monthly benefit at retirement, typically based on years of service and compensation history. Unlike 401(k) plans, the investment risk falls on the employer, making accurate financial reporting and independent auditing especially critical.

ERISA requires plan sponsors to have their defined benefit plans independently audited each year by a licensed CPA when the plan covers 100 or more participants. The audit report must be filed with Form 5500 with the Department of Labor and must examine plan assets, benefit obligations, and administrative compliance.

Defined benefit plan audits are more complex than 401(k) audits due to the involvement of actuarial valuations, benefit payment accuracy, PBGC reporting, and the interaction between plan assets and projected benefit obligations (PBO).

Defined Benefit Plan Audit FAQs

How is a defined benefit plan audit different from a 401(k) audit?

Defined benefit audits are more complex due to actuarial involvement, benefit payment accuracy testing, PBGC compliance, and the interaction between plan assets and projected benefit obligations. They require deeper coordination with actuaries and trustees.

What is the PBGC and why does it matter in the audit?

The Pension Benefit Guaranty Corporation (PBGC) insures defined benefit pension benefits. Plan sponsors must pay annual PBGC premiums. Our audit verifies that required premiums were accurately calculated and timely paid.

Do we need to coordinate with our actuary?

Yes. We review and rely on actuarial reports for benefit obligation disclosures. We coordinate directly with your plan's enrolled actuary to obtain the information needed for audit procedures and financial statement disclosures.

What happens if our plan is underfunded?

Underfunded plans face minimum funding requirements under IRC Section 430 and may have reporting obligations to participants and the PBGC. Our audit identifies funding status and reviews compliance with applicable funding requirements and disclosures.
