Hey Broker-Dealers! You already understand the ins and outs of financial markets, risk-return analysis, and the trust your clients place in you because of your expertise. However, beyond selecting the right securities and strategies, there is something equally critical—audits.
Audits aren’t just about ticking compliance boxes or avoiding penalties—they’re a powerful tool to build transparency, reinforce client confidence, and demonstrate that your firm operates with integrity and accountability. In today’s regulatory environment, staying audit-ready is not just good practice—it’s a competitive advantage.
But before diving deeper into the topic, let’s first understand who qualifies as a broker or dealer under the definitions provided by the Securities and Exchange Commission (SEC).
Broker- In simple terms, a broker acts as an agent for investment advisors, independent contractors, financial consultants, and placement agencies. They earn profit from commissions.
Dealer – In simple terms, a dealer acts as a principal, buying and selling securities for themselves and earning a profit from price changes, rather than charging a fee.
And many firms act as both brokers and dealers. That’s why they are referred to as broker-dealers.
Being classified as a broker or dealer triggers licensing, compliance, and reporting requirements under U.S. securities laws. In this blog, we will cover all the legal requirements for a broker-dealer:
Registration Requirements for Broker-Dealers
In the US, an individual can’t be called individually a broker, a dealer, or together as a broker-dealer if they don’t fulfill the following registration requirements:
| Entity Type | Required Registration Bodies | Notes |
| Broker | SEC, FINRA, and State Regulators (as applicable). | Must also register with each exchange they plan to access (e.g., NYSE, NASDAQ). |
| Dealer | SEC, FINRA (if serving retail), and State Regulators. | Proprietary trading firms may still need FINRA registration if they are public-facing. |
| Broker-Dealer | SEC + FINRA + SIPC + State Regulators | Most comprehensive registration; subject to full compliance & auditing |
What is a broker-dealer audit, and why is it important?
A broker-dealer audit is a comprehensive, independent examination of a broker-dealer’s financial record, operations, and all internal controls, required by U.S. law and conducted annually by a PCAOB-registered firm. It ensures that the firm is set by the Securities and Exchange Commission (SEC) and the Financial Industry Regulatory Authority (FINRA).
Why is it so important?
- Protects investors: Audits ensure that client assets are safe, managed ethically, and transparently.
- Builds credibility: Audited broker-dealers earn greater trust from investors, partners, and regulators.
- Avoids penalties: By staying compliant with audits and fulfilling filing requirements, you can avoid fines or even license suspension and revocation, which may depend on the specific case.
- Supports market integrity: Accurate financial and operational reporting promotes a fair and stable financial system.
Audit Related Requirements for Broker-Dealer
Broker-dealers are required to maintain certain audit-related filings as per regulations:
- Annual audit requirement (SEC Rule 17a-5(d))
- This rule says that broker-dealers must file audited financial statements annually
- A PCAOB-registered independent public accountant must conduct the audit.
2. Statement of financial position (Focus Report)
- File monthly, quarterly, or annually
- Submitted through FINRA’s gateway system
3. Compliance Report/ Examination Report
- Compliance Report: The broker-dealer must include a compliance report if it is not exempt from SEC Rule 15c3-3.
- Exemption Report: Broker-dealer must file an exemption report if it is exempt from SEC Rule 15c3-3
4. Custody Rule considerations(Rule 15c3-3)
Must file if the broker-dealer has custody of customer assets. It can be subject to additional audit scrutiny under the custody provisions.
5. AML audits
Anti-Money Laundering is a program by FINRA to ensure that firms detect and report suspicious activity. It determines whether the policies, procedures, and practices are adequately designed to comply with requirements by current government guidelines.
All SEC-registered broker-dealers are required to undergo AML audits, regardless of their size or business model.
There is no exemption, including for firms that do not hold customer funds, and are fully disclosed introducing firms and engaged only in proprietary trading.
6. SPIC-6 and SPIC-7
These are mandatory annual statements forms filled with SPIC(Securities Investor Protection Corporation).
SIPC-6 is the interim filing due by July 31st (filed for the first half of the fiscal year) covering estimated net operating revenues for the first half of the year.
SIPC-7 is the final filing, due 60 days after the fiscal year-end, and reconciles actual full-year revenues with any interim payments made. If the broker-dealer’s annual gross revenues exceed $500,000, SIPC-7 must be accompanied by a supplemental auditor’s report. Both forms help the SIPC determine the firm’s required contribution to the investor protection fund.
7. Form U4 and U5
Form U4 (Uniform Application for Broker-Dealer Registration) is used to register brokers, advisors, or portfolio managers who will represent the broker-dealer firm. It is also used when an existing representative joins a new firm.
Form U5 (Uniform Termination) is filled out when a representative leaves or is terminated. It updates FINRA records to show that the person is no longer with that firm.
8. Form BD & Form BR (For Broker-Dealer firms)
Form BD is used to register a broker-dealer firm with the SEC and FINRA. This form includes details about the firm’s business, operations, and ownership.
Form BR is used to register each branch office of the broker-dealer. If your firm has multiple office locations, each one needs to be registered using this form.
Deadlines
| Filing | Deadline |
| Annual Audit (BDs) | Within 60 days of the fiscal year-end |
| Form 10-K | 60-90 days after fiscal year-end (depending on filer status) |
| Form 10-Q | 40-45 days after each fiscal quarter |
| Form ADV (RIAs) | Within 90 days of the fiscal year-end |
| SIPC Report | Within 60 days of the fiscal year-end |
PCAOB Reporting
Auditors play a vital role in ensuring financial transparency and regulatory compliance, and PCAOB regulations mandate specific disclosures and standards that must be followed to uphold audit integrity.
One critical aspect that broker-dealers must not overlook is the importance of audit reporting requirements under PCAOB regulations.
The independent audit firm must be registered with the Public Company Accounting Oversight Board (PCAOB). The audit firm is required to file a Form AP disclosing the engagement partner for each audit report.
