PCAOB broker-dealer audits are a core regulatory requirement for SEC Rule 17a-5 compliance. However, as standards evolve and PCAOB inspections highlight recurring deficiencies, many firms are reevaluating what they actually need from their audit partner.

Understanding the required audit components and how expectations are changing is the first step toward a smooth, compliant engagement.

 

Key Takeaways

  • Broker-dealer audits include three required components: a financial statement audit, a review of the exemption report, and an attestation of supplemental information under Rule 17a-5.
  • 2026 will bring heightened expectations for documentation, quality control, and fraud-focused procedures, driven by the PCAOB’s new QC 1000 standard and ongoing inspection priorities.
  • Audit readiness is the biggest factor in avoiding delays or findings, making the right audit partner essential for a smooth engagement.

 

What’s Included in PCAOB Broker-Dealer Audits?

Under Rule 17a-5, most SEC-registered broker-dealers are required to undergo three audit components annually. To understand each component, it’s helpful to look at them separately.

1. Financial Statement Audit

The financial statement audit is the core of the engagement. An audit professional examines financial statements under PCAOB standards, focusing on:

  • Accuracy
  • Completeness
  • Compliance with U.S. GAAP (Generally Accepted Accounting Principles)

Areas like revenue recognition, related-party transactions, and net capital calculations often receive heightened scrutiny. Your audit partner may spend additional time reviewing these sections to ensure they align with the standards. 

2. Review of the Exemption Report

For broker-dealers that file under an exemption from SEC Rule 15c3-3, the audit includes a review of the exemption report prepared by management. The broker-dealer auditors will review procedures to ensure a firm’s assertions are true. 

This review is particularly beneficial for customer protection requirements and the custody of customer assets. Misalignment between actual practices and an exemption claim is one of the most common findings in PCAOB inspections.

3. Attestation of Supplemental Information

A PCAOB broker dealer audit often requires supplemental information, such as Net Capital Computation or a reconciliation report. These additional requirements must be accurately and fully supported with documentation.

As part of the audit, an audit firm will review the attestation procedures to ensure that the submitted information is tied back to the underlying books and records. Incomplete or inconsistent supplemental schedules often result in delays.

 

What Changed in 2025?

Broker-dealer audits are often complex, and navigating this complexity can be challenging for firms unfamiliar with Rule 17a-5 or new regulatory requirements and expectations.

Here’s what’s changed in 2025 and what’s worth paying attention to in 2026 and beyond. 

 

New QC 1000 Standard

By December 15, 2026, PCAOB-registered firms must adopt QC 1000. This is a strengthened system of quality control that emphasizes:

  • Documentation
  • Risk assessment
  • Internal oversight. 

Broker-dealers should expect more structured requests and clearer evidence requirements from their auditors.

 

Higher Inspection Focus on Risk & Fraud

Although the audit deficiency rate decreased in 2024, there remains a focus on continuing to reduce deficiencies. This means, auditing partners will place deeper attention on:

  • Fraud risk assessments
  • Revenue streams and fee arrangements
  • Net capital computations
  • Internal controls over financial reporting
  • Documentation supporting exemption claims

 

Avoiding Audit Pitfalls

Audit readiness is often what separates smooth engagements from stressful ones. Broker-dealers can reduce risk by:

  • Maintaining complete, accurate books and closed periods
  • Documenting internal controls and key processes
  • Starting audit planning early to avoid last-minute document requests
