Employee Benefit Plan Audit Outsourcing for CPA & Accounting Firms – Why It Matters
Summary
How outsourcing employee benefit plan (EBP) audit support helps CPA firms — 401(k), 403(b), pension, H&W, ESOP — under SAS 136, avoiding the common DOL deficiencies.
EBP audits carry outsized risk for the effort: the DOL actively reviews plan audits and rejects deficient ones, yet the work is seasonal and specialized. Outsourcing EBP audit support lets your firm serve more plan clients by moving the workpaper preparation to a team trained specifically in ERISA plan audits — while your licensed auditors keep the opinion and the responsibility.
This guide covers the plan types, what's prepared, the standards, and the deficiencies a good partner helps you avoid.
Which plans need an EBP audit
ERISA generally requires an independent audit for large plans — 100+ eligible participants for defined-contribution plans (401(k), 403(b), profit-sharing), defined-benefit pension plans over the DOL asset threshold, and health-and-welfare plans with 100+ participants.
Every EBP type, supported
- 401(k) / profit-sharing — participant, contribution, distribution, and investment testing
- 403(b) — elective deferrals, the universal-availability requirement, plan-loan and hardship rules
- Defined-benefit pension — actuarial valuation testing (reconciling ASC 715 disclosures to the actuary's report), plan-asset and benefit-payment testing
- Health & welfare — claims paid and IBNR liabilities, stop-loss reconciliation, FSA testing
- ESOP — employer-security valuation, appraiser independence (per DOL/ERISA), share-price reconciliation
What's prepared (you keep the opinion)
Workpapers for all required areas, ASC 960 plan financial statements, and the Form 5500 schedules that accompany them — Schedule H, Schedule of Assets Held, Reportable Transactions, and Delinquent Participant Contributions. Your firm assesses risk, reviews, and signs; the offshore team prepares.
Standards & avoiding DOL deficiencies
Work follows SAS No. 136, the AICPA EBP Audit & Accounting Guide, and DOL Field Assistance Bulletins — and is built to satisfy the DOL's rejection-criteria checklist. The most-cited DOL deficiencies a disciplined process prevents: inadequate investment testing, failure to test prohibited transactions, insufficient participant-data testing, weak going-concern evaluation, and missing required disclosures.
Why outsourcing it works
Seasonal EBP capacity without seasonal hiring, at up to 70–75% less than in-house staff for the same preparatory work — so your firm can grow its plan-audit practice profitably.
