Section 206 of the Advisers Act: Rules, Fiduciary Duty, and Penalties

Section 206 of the Investment Advisers Act of 1940, codified at 15 U.S.C. § 80b-6, is the federal anti-fraud rule for investment advisers. It prohibits schemes to defraud clients, negligent conduct that operates as a fraud, undisclosed principal and agency cross trades, and any other practice the SEC has defined as fraudulent by rule. Violators face SEC injunctions, registration suspensions or revocations, disgorgement, civil penalties that scale with the seriousness of the conduct, and, in serious cases, referral for criminal prosecution.

Who Section 206 Reaches

Most of the Advisers Act governs only firms registered with the SEC. Section 206 is the exception. It applies to anyone who meets the statutory definition of “investment adviser”—registered, exempt from registration, or operating unlawfully without registering at all.¹ If you give securities advice for compensation as a business, the anti-fraud rules attach.

The Four Subsections

Section 206 is built from four numbered prohibitions, each doing distinct work.²

206(1): Intentional Fraud

Subsection (1) bars any device, scheme, or artifice to defraud a client or prospective client. To win a 206(1) case the SEC must prove scienter, meaning the adviser acted with intent to deceive or reckless disregard for the truth.³

206(2): Negligent Fraud

Subsection (2) prohibits any transaction, practice, or course of business that operates as a fraud or deceit on a client or prospective client. The critical difference from 206(1) is the standard of proof: negligence is enough. The SEC does not have to show the adviser meant any harm.³ That lower bar is where a large share of enforcement lives.

206(3): Principal and Agency Cross Trades

Subsection (3) targets two specific conflicts. A principal transaction is one where the adviser trades with the client out of the adviser’s own account. An agency cross transaction is one where the adviser acts as broker for both sides. In either case, the adviser must disclose its role in writing before the trade settles and obtain the client’s consent.² Principal-trade consent must be obtained trade by trade. Agency cross transactions can proceed under advance blanket consent, but only after the adviser has provided full written disclosure of the conflicts, including the fact that it will earn commissions from both sides.⁴

206(4): The SEC’s Rulemaking Hook

Subsection (4) authorizes the SEC to define and prohibit, by rule, any additional practice it considers fraudulent, deceptive, or manipulative.² Most of the day-to-day compliance obligations on advisory firms sit here, in rules the Commission has written using 206(4) authority.

The Fiduciary Duty

The Supreme Court read a fiduciary duty into the statute in SEC v. Capital Gains Research Bureau, Inc. (1963). The Court held that Congress intended the Act to be read broadly enough to expose all conflicts of interest that could taint an adviser’s recommendations, whether the adviser acted consciously or not.⁵ In 2019 the SEC issued a formal interpretation dividing that duty into two components.³

The duty of care requires the adviser to give advice that is in the client’s best interest based on a reasonable understanding of the client’s financial goals, to seek best execution when selecting broker-dealers, and to provide ongoing advice and monitoring appropriate to the relationship.

The duty of loyalty requires the adviser not to put its own interests ahead of the client’s, and to make full and fair disclosure of all material conflicts. The 2019 interpretation was explicit that disclosure is not a get-out-of-jail card: even after disclosing a conflict and obtaining informed consent, the adviser still has to act in the client’s best interest.

The 206(4) Rules That Do the Real Work

The prohibitions in the statute itself are broad. The specific conduct rules advisers spend their compliance budgets on come from Rule 206(4), where the SEC has built out detailed requirements in several areas.

Marketing (Rule 206(4)-1)

Rule 206(4)-1 contains seven general prohibitions covering advertising, including bans on untrue statements of material fact, unsubstantiated claims, misleading implications, and cherry-picked performance.⁶ Any discussion of potential benefits must be fair and balanced with the associated risks.

The modernized rule allows testimonials and endorsements but requires clear disclosure of whether the person is a client and whether they were paid. A written agreement with the endorser is required unless the endorser is an affiliate or received less than $1,000 in compensation over the preceding twelve months. People with certain regulatory or criminal histories cannot serve as paid promoters.⁷ Whenever an advertisement shows gross performance, net performance must appear alongside it with equal prominence.⁸

Custody (Rule 206(4)-2)

Advisers who hold or have access to client funds and securities must keep those assets with a qualified custodian—a bank, broker-dealer, or futures commission merchant—in accounts separated by client. The default rule requires an annual surprise examination by an independent public accountant, conducted at an irregular time chosen by the accountant without advance notice.⁹ Some narrow exceptions exist, including for advisers whose only custody authority is deducting advisory fees.¹⁰

Pay-to-Play (Rule 206(4)-5)

Rule 206(4)-5 bars an adviser from providing advisory services for compensation to a government entity for two years after the adviser or any covered employee makes a political contribution to an official who can influence that entity’s selection of advisers.¹¹ A modest contribution to the wrong official can cost a firm a two-year ban on the resulting business.

Compliance Programs (Rule 206(4)-7)

Every SEC-registered adviser must adopt written compliance policies and procedures reasonably designed to prevent Advisers Act violations, designate a chief compliance officer, and conduct an annual review of the program’s adequacy.¹² The SEC has brought enforcement actions on this rule alone, without any underlying fraud, where the compliance infrastructure was inadequate.

Private Fund Investors (Rule 206(4)-8)

Rule 206(4)-8 fills a gap for pooled investment vehicles like hedge funds and private equity funds. It prohibits an adviser to a pooled vehicle from making untrue statements or misleading omissions to any investor or prospective investor in the fund, and from engaging in any other fraudulent or deceptive conduct directed at those investors.¹³ Sections 206(1) and (2) protect “clients,” and courts had debated whether limited partners counted as clients of the fund’s adviser. This rule protects them directly, and the SEC has enforced it on a negligence standard.

Enforcement Runs Through the SEC

Section 206 does not give investors the right to sue their adviser for damages. In Transamerica Mortgage Advisors, Inc. v. Lewis (1979), the Supreme Court held that Section 206 “simply proscribes certain conduct” and does not create a private cause of action.¹⁴ Clients who believe their adviser committed fraud generally have to look to state law claims, breach-of-contract theories, or FINRA arbitration where the adviser is also a broker-dealer. The federal statute itself is enforced by the SEC.

The Commission can proceed in its own administrative forum or file suit in federal district court. It can seek injunctions, which courts must grant without requiring a bond.¹⁵ In administrative proceedings, the SEC can censure an adviser, restrict their business activities, suspend their registration for up to twelve months, or revoke it.¹⁶

Penalties

Civil Monetary Penalties

Financial penalties run in three tiers, adjusted periodically for inflation. The current per-violation figures, which remain at 2025 levels for 2026 due to a delay in CPI data publication, are:¹⁷

Tier 1, basic violations: up to $11,823 per violation for an individual, or $118,225 for a firm.
Tier 2, fraud or reckless disregard of a regulatory requirement: up to $118,225 per violation for an individual, or $591,127 for a firm.
Tier 3, fraud causing substantial losses to others or substantial gains to the adviser: up to $236,451 per violation for an individual, or $1,182,251 for a firm.

These are per-violation caps. A pattern of misconduct across multiple clients or transactions multiplies quickly.

Disgorgement and Industry Bars

The SEC routinely seeks disgorgement, an order requiring the adviser to return profits earned through the illegal conduct. It can also bar individuals from associating with any registered advisory firm or broker-dealer, which effectively ends a career in the industry.

Criminal Referrals

Section 206 is a civil statute, but the Advisers Act authorizes the SEC to transmit evidence to the Attorney General for criminal prosecution.¹⁵ The Department of Justice can pursue charges independently of any SEC civil action. Criminal cases carry higher fines and possible prison time, and tend to involve deliberate, egregious fraud rather than the negligence-based conduct that fills the SEC’s administrative docket.
