SEC Rule 506

Rule 506(b) addresses this uncertainty by providing objective safe harbour conditions under which the Section 4(a)(2) exemption is available as a matter of law. An issuer that satisfies Rule 506(b)'s conditions — no general solicitation, sales only to accredited investors and up to 35 non-accredited sophisticated purchasers, information delivery to non-accredited investors, and compliance with the bad actor disqualification framework — can be confident that its offering qualifies for the Section 4(a)(2) exemption without undertaking the facts-and-circumstances analysis that the judicial standard otherwise requires. The safe harbour character of Rule 506(b) is therefore not merely a semantic label — it provides genuine legal certainty that transforms the commercial viability of private capital formation by removing the uncertainty that would otherwise attach to every private offering relying on the open-ended Ralston Purina standard.

The scale of the Rule 506(b) market reflects the commercial significance of this certainty. Form D data published by the Division of Economic and Risk Analysis for the period ending December 31, 2024 confirmed that Regulation D offerings — overwhelmingly dominated by Rule 506(b) — collectively reported more than $3.7 trillion in aggregate capital raised across approximately 32,000 offerings in 2024, exceeding the amount raised in registered public offerings for the same period. The private capital market enabled by Rule 506(b) is not a niche alternative to the public markets — it is a primary mechanism for capital allocation in the modern economy.

Statutory Authority and Rulemaking History

Rule 506(b) derives its statutory authority from Section 4(a)(2) of the Securities Act of 1933 — the non-public offering exemption — and Section 19(a), which provides the Commission's general rulemaking authority. Rule 506 was originally adopted as part of the Regulation D package in Securities Act Release No. 33-6389, March 16, 1982, codifying the safe harbour that had been developed through prior Commission guidance and no-action letter practice. The original Rule 506 provided the core conditions that continue to define Rule 506(b) today — no general solicitation, accredited investor participation without limit, up to 35 non-accredited sophisticated purchasers, information delivery obligations, and no limit on the aggregate offering amount.

The rule's most significant subsequent amendments were: the 2013 bad actor disqualification rulemaking, Securities Act Release No. 33-9414, September 23, 2013, which added Rule 506(d) and Rule 506(e) to the framework; and the 2021 Exempt Offering Framework rulemaking, Securities Act Release No. 33-10884, January 14, 2021, which added the 90-calendar-day rolling period for the 35 non-accredited investor limit. 

The 2013 bad actor amendments were mandated by Section 926 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which directed the Commission to adopt rules disqualifying felons and other bad actors from participation in Rule 506 offerings. The eCFR confirms January 14, 2021 as the date of the most recent amendment to Rule 506, with no subsequent amendments through June 2026. The INVEST Act, which passed the House of Representatives in December 2025, includes provisions addressing the exempt offering framework but has not been enacted into law, and no formal rulemaking proposing amendments to Rule 506(b) has been published through June 2026.

Key Provisions and Operative Requirements

Rule 506(b)(1) establishes the no-general-solicitation condition. Neither the issuer nor any person acting on its behalf may offer or sell the securities by any form of general solicitation or general advertising within the meaning of Rule 502(c). The prohibition encompasses advertisements, articles, notices, or other communications published in any newspaper, magazine, or similar media or broadcast over television, radio, or electronic communication networks accessible to the general public; seminars or meetings whose attendees have been invited by any general solicitation or general advertising; and any other communication directed at investors generally rather than at a defined group with whom the issuer has a pre-existing substantive relationship. 

The prohibition is absolute: a single act of general solicitation in connection with a Rule 506(b) offering contaminates the entire offering and causes it to lose the Rule 506(b) safe harbour for all investors in the offering, not merely those reached through the general solicitation.

The concept of a pre-existing substantive relationship is the central analytical tool for navigating the general solicitation prohibition. The Commission has articulated through no-action letters and interpretive guidance that a communication is not general solicitation where it is directed at persons with whom the issuer has a pre-existing substantive relationship — a relationship established before the commencement of the offering and through which the issuer has acquired enough information about the investor's financial circumstances or sophistication to evaluate whether the investor is an appropriate participant in the offering. 

A March 12, 2025 C&DI confirmed that registered investment advisers may form pre-existing substantive relationships with prospective offerees sufficient to negate the general solicitation concern, extending prior guidance on broker-dealer relationships to include investment adviser client relationships as a qualifying pre-existing substantive relationship.

Rule 506(b)(2) establishes the investor eligibility conditions. The issuer may sell securities to an unlimited number of accredited investors as defined in Rule 501(a). In addition, the issuer may sell to up to 35 other purchasers who satisfy the sophistication standard — purchasers who, either alone or together with a purchaser representative, have such knowledge and experience in financial and business matters that they are capable of evaluating the merits and risks of the prospective investment. 

The 90-calendar-day rolling period for the 35 non-accredited investor limit was added by the 2021 amendment, replacing the prior per-offering count that had allowed issuers to include 35 non-accredited investors in each of a series of sequential offerings. Under the amended framework, an issuer conducting multiple Rule 506(b) offerings in close succession may not include more than 35 non-accredited investor purchasers across all such offerings within any 90-calendar-day period.

The sophistication standard applicable to non-accredited investors is evaluated on an objective basis — the purchaser must actually have sufficient knowledge and experience in financial and business matters to evaluate the investment, not merely assert that they have it. Where a non-accredited investor cannot independently satisfy the sophistication standard, the investor may satisfy it through a purchaser representative as defined in Rule 501(h), who must be independent of and unaffiliated with the issuer and its principals, must have such knowledge and experience in financial and business matters that he or she is capable of evaluating the merits and risks of the investment, must acknowledge in writing that he or she is acting as the purchaser's representative in the transaction, and must disclose to the purchaser any material relationship between the purchaser representative and the issuer or its principals.

The information obligations under Rule 502(b) apply where non-accredited investors participate in a Rule 506(b) offering. The issuer must provide those investors with disclosure documents meeting the standards specified in Rule 502(b)(2) — Form 1-A level disclosure for offerings up to $20 million, registration statement level disclosure for offerings above that amount — a reasonable time before the sale. 

The issuer must also make itself available to answer questions from prospective purchasers and must provide the same information to accredited investors if it provides any information under Rule 502(b) to non-accredited investors in the same offering. In practice, the information delivery requirement for non-accredited investors is one of the principal reasons that most Rule 506(b) issuers limit participation exclusively to accredited investors — the cost and complexity of preparing compliant disclosure documents for non-accredited investors is substantial and is avoided entirely where the offering is limited to accredited investors.

Rule 506(b)'s investor verification standard is reasonable belief — the issuer need not obtain documentary verification of each investor's accredited status but must reasonably believe that each purchaser is an accredited investor based on information available to the issuer at the time of the sale. This reasonable belief standard is meaningfully less demanding than the affirmative verification obligation imposed by Rule 506(c), and in practice is typically satisfied through an accredited investor questionnaire or representation letter completed by the investor, supplemented by whatever additional diligence the circumstances warrant.

Rule 506(d) — the bad actor disqualification provision — renders Rule 506(b) unavailable for offerings in which any covered person has experienced a disqualifying event. Covered persons include the issuer and its predecessors and affiliated issuers; any director, executive officer, general partner, or managing member of the issuer; any beneficial owner of 20% or more of the issuer's outstanding voting equity securities; any promoter connected with the issuer in any capacity; any person that has been or will be paid, directly or indirectly, remuneration for solicitation of purchasers in connection with the offering; any general partner, managing member, director, or executive officer of any such compensated solicitor; and any underwriter. Disqualifying events include felony or misdemeanor criminal convictions related to securities fraud or false SEC filings; SEC enforcement orders; court injunctions and restraining orders related to securities law violations; final orders from state securities, federal banking, or other specified financial regulators; suspension or expulsion from FINRA or other SRO membership; U.S. Postal Service false representation orders; and registration stop orders.

Rule 506(e) provides the disclosure requirement for pre-2013 events. Where a covered person has experienced a disqualifying event that occurred before September 23, 2013 — the effective date of the bad actor disqualification provisions — the issuer must furnish to each purchaser a reasonable time prior to sale a written description of any such matters. This disclosure obligation ensures that investors receive information about covered persons' prior adverse histories even where those histories predate the disqualification provision's operative date.

Scope of Application

Rule 506(b) is available to all issuers regardless of size, industry, reporting status, or organizational form — unlike the registered offering framework, which conditions the choice of registration form on the issuer's Exchange Act reporting history and public float, and unlike Rule 504, which excludes Exchange Act reporting companies, investment companies, and blank check companies. Rule 506(b) is available to operating companies of all sizes, private equity and venture capital funds, real estate investment funds, hedge funds, family offices, startup companies, and any other issuer seeking to raise capital through a private placement structure. The only categorical issuer exclusions are those imposed by the bad actor disqualification framework — an issuer whose covered persons have experienced disqualifying events is excluded from Rule 506(b) regardless of its other characteristics.

Securities sold under Rule 506(b) are covered securities under Section 18(b)(4)(D) of the Securities Act as added by the National Securities Markets Improvement Act of 1996. This covered security status preempts state securities registration and qualification requirements — a Rule 506(b) offering is exempt from state blue sky registration in all 50 states. States may require notice filings and may charge notice filing fees, and most states have adopted notice filing requirements for Rule 506(b) offerings through which they receive copies of the Form D filed with the Commission. However, states may not condition the availability of the Rule 506(b) exemption on state review, qualification, or approval of the offering.

Relationship to Related Rules and Regulations

Rule 506(b) is structurally inseparable from the broader Regulation D framework. Its conditions cross-reference Rule 501 for the accredited investor and purchaser representative definitions, Rule 502(b) for information delivery obligations, Rule 502(c) for the general solicitation prohibition, Rule 502(d) for resale restrictions, Rule 152 for integration analysis, and Rule 503 for Form D filing requirements. These cross-references are not merely administrative — they define the entire compliance framework applicable to a Rule 506(b) offering.

The relationship between Rule 506(b) and Rule 506(c) is one of mutual exclusivity. An issuer must elect either the no-solicitation framework of Rule 506(b) or the general solicitation framework of Rule 506(c) — the two cannot be used simultaneously for the same offering. Once a general solicitation has been made in connection with an offering, the issuer can no longer rely on Rule 506(b) for that offering and must either satisfy Rule 506(c)'s accredited-investor-only verification requirements or accept that the offering is not exempt from registration.

For broker-dealers participating as placement agents in Rule 506(b) offerings, FINRA Rule 5123 requires that the broker-dealer file with FINRA, within 15 calendar days of the date of first sale, any private placement memorandum, term sheet, or other offering document used in connection with the offering, or notify FINRA that no such documents were used. FINRA Rule 5122 governs private placements of securities issued by member firms and their affiliates. These FINRA filing and disclosure requirements apply alongside — not in lieu of — the federal Rule 506(b) conditions.

Amendment History and Regulatory Evolution

Rule 506(b)'s core structure has remained essentially unchanged since 1982, reflecting the Commission's sustained confidence in the safe harbour's basic design. The most significant amendments have been additive rather than structural — the 2013 bad actor provisions adding a new layer of eligibility screening, and the 2021 rolling period amendment modifying the non-accredited investor limit's temporal structure. The rule's foundational elements — unlimited accredited investor participation, 35 non-accredited investor cap, no general solicitation, no offering amount ceiling, and reasonable belief verification — have been stable for over four decades.

The most significant development in the Rule 506(b) landscape since the 2021 amendment is the Commission's progressive refinement of the general solicitation prohibition's application in the digital communications environment. C&DI guidance has addressed social media communications, venture fair and demo day participation, online intermediary platforms, and investment adviser client outreach — progressively updating the general solicitation framework to address communication methods that did not exist when the prohibition was originally conceived. The March 12, 2025 C&DI on investment adviser pre-existing relationships represents the most recent significant interpretive update in this area.

Enforcement Context and SEC Action Patterns

The Commission's enforcement activity in the Rule 506(b) context is extensive and spans the full range of the rule's conditions. The general solicitation prohibition generates the largest volume of enforcement referrals — issuers that have used social media, public websites, mass email campaigns, or public pitch events to market Rule 506(b) offerings have been the subject of both informal staff correspondence requiring remediation and formal enforcement proceedings. The Commission has consistently taken the position that the general solicitation prohibition is strictly applied and that a single public communication about an offering's existence and terms constitutes general solicitation that contaminates the entire offering.

The accredited investor qualification and verification requirements generate a steady stream of enforcement actions involving issuers that have characterised non-qualifying investors as accredited, failed to conduct any meaningful accredited investor assessment, or deliberately misrepresented investors' qualifying status in Form D filings. The reasonable belief standard does not excuse complete absence of inquiry — an issuer that accepts a purchaser's self-certification without any corroborating assessment has not satisfied the reasonable belief standard where the circumstances should have alerted it to doubts about the investor's qualifications.

The bad actor disqualification framework has generated a category of enforcement action focused specifically on issuers that have failed to conduct adequate covered person diligence before commencing a Rule 506(b) offering. The Commission has brought actions against issuers that proceeded with offerings without discovering disqualifying events in their covered persons' backgrounds that a reasonable inquiry would have revealed, and has treated the consequent loss of the Rule 506(b) exemption as a Section 5 violation for all sales made in the tainted offering.

The Office of Examinations and FINRA's examination programme both include Rule 506(b) compliance as a priority area for broker-dealer placement agents, with particular focus on general solicitation practices, accredited investor diligence procedures, and compliance with the FINRA Rule 5123 offering document filing requirement.

Examination Relevance and Key Takeaways

Rule 506(b) is among the most heavily examined concepts across the SIE, Series 7, Series 65, and Series 66 examinations. Candidates should understand all core conditions: the prohibition on general solicitation and the pre-existing substantive relationship concept that defines its boundary; the unlimited accredited investor participation and the 35 non-accredited sophisticated purchaser limit within any 90-calendar-day period; the sophistication standard for non-accredited investors and the purchaser representative mechanism; the information delivery obligations under Rule 502(b) that apply where non-accredited investors participate; the reasonable belief verification standard applicable to accredited investor status determinations; and the bad actor disqualification framework and its covered person categories and triggering events.

The distinction between the reasonable belief verification standard of Rule 506(b) and the affirmative reasonable steps verification obligation of Rule 506(c) is a consistently examined concept, as is the mutual exclusivity of the two exemptions — an issuer that engages in general solicitation cannot rely on Rule 506(b). The covered security status of Rule 506(b) offerings — preempting state blue sky registration requirements — is examined in the context of state and federal securities law interaction.

The key points to retain are these. Rule 506(b) is the traditional private placement safe harbour under Section 4(a)(2) of the Securities Act, providing the most widely used exemption from registration in the United States private capital markets. The rule permits issuers to raise unlimited capital from an unlimited number of accredited investors, with no information delivery obligation to accredited investors and no restriction on offering size. 

Up to 35 non-accredited sophisticated purchasers may participate within any 90-calendar-day period, subject to mandatory information delivery and the sophistication requirement. General solicitation and general advertising are strictly prohibited — a single general solicitation contaminates the entire offering. Accredited investor verification requires reasonable belief rather than affirmative documentation. Securities are covered securities exempt from state registration requirements, though notice filings are commonly required. Bad actor disqualification under Rule 506(d) applies to a broad range of covered persons, with pre-2013 events requiring written pre-sale disclosure under Rule 506(e). Rule 506 was last amended January 14, 2021 and no amendments are pending as of June 2026.
