Introduction

Regulation D represents the most widely used exemption from SEC registration requirements for private securities offerings in the United States. Since its adoption in 1982, Regulation D has facilitated over $1.5 trillion in annual capital formation, accounting for approximately 90% of all private placements. Understanding the precise language and requirements of Regulation D is essential for issuers, fund managers, attorneys, and compliance professionals who structure private offerings.

This comprehensive guide provides a word-for-word breakdown of Regulation D's key provisions, with practical explanations of how each rule applies in real-world capital raising scenarios. Whether you're conducting your first private placement or your fiftieth, this guide will serve as your authoritative reference for navigating Regulation D's requirements, limitations, and safe harbors.

What is Regulation D and Why Does It Matter?

Regulation D provides a series of safe harbor exemptions under Section 4(a)(2) of the Securities Act of 1933, which exempts "transactions by an issuer not involving any public offering" from registration requirements. The regulation codifies and clarifies the private offering exemption, establishing clear standards that issuers can follow to ensure their offerings qualify for exemption status. When properly structured and executed, Regulation D offerings allow companies to raise unlimited capital without the extensive disclosure requirements, audited financial statements, and ongoing reporting obligations associated with registered public offerings.

The regulation consists of six rules (Rules 501 through 506) and several preliminary notes that establish definitions, conditions, and safe harbors. The most commonly used provisions are Rule 506(b) and Rule 506(c), which together account for over 95% of all Regulation D offerings. Understanding the precise language of these rules is critical because even minor deviations from the regulatory requirements can result in loss of the exemption, giving investors rescission rights and exposing issuers to SEC enforcement actions.

The Structure of Regulation D

Regulation D is organized into six primary rules that work together to create a comprehensive framework for private offerings:

RulePurposeKey Provision
Rule 501Definitions and TermsDefines "accredited investor," "aggregate offering price," and other key terms
Rule 502General ConditionsEstablishes integration, information requirements, and resale limitations
Rule 503Filing RequirementsMandates Form D filing within 15 days of first sale
Rule 504Small OfferingsExemption for offerings up to $10 million (rarely used)
Rule 505Offerings up to $5MRepealed in 2016, no longer available
Rule 506Unlimited OfferingsProvides two pathways: 506(b) and 506(c) for unlimited capital raises

The following sections provide word-for-word analysis of the most critical provisions that govern modern private placements.

Rule 501: Definitions and Terms

Rule 501 establishes the foundational definitions that apply throughout Regulation D. The most consequential definition is that of "accredited investor," which determines who can invest in most private offerings.

Accredited Investor Definition (Rule 501(a))

The regulation defines an accredited investor as any person who falls within one of several categories. For natural persons, the two most common qualification methods are:

Income Test: Any natural person whose individual income exceeded $200,000 in each of the two most recent years, or whose joint income with a spouse exceeded $300,000 in each of those years, and who has a reasonable expectation of reaching the same income level in the current year.

Net Worth Test: Any natural person whose individual net worth, or joint net worth with a spouse, exceeds $1,000,000 at the time of purchase, excluding the value of the person's primary residence.

The 2020 amendments to the accredited investor definition added several new qualification categories, including individuals holding Series 7, Series 65, or Series 82 securities licenses, and individuals who are "knowledgeable employees" of private funds. These expansions recognize that financial sophistication can be demonstrated through professional credentials and experience, not merely wealth.

For entities, the accredited investor definition includes banks, insurance companies, registered investment companies, business development companies, small business investment companies, employee benefit plans with assets exceeding $5 million, trusts with assets exceeding $5 million that are not formed specifically to acquire the securities, and any entity in which all equity owners are accredited investors.

Aggregate Offering Price (Rule 501(c))

The regulation defines "aggregate offering price" as the sum of all cash, services, property, notes, cancellation of debt, or other consideration received by an issuer for issuance of its securities. This definition is critical for determining whether an offering falls within the monetary limits of Rule 504 or whether it qualifies for the unlimited offering size permitted under Rule 506.

The calculation of aggregate offering price requires careful attention to the integration doctrine, which may combine multiple offerings into a single offering for purposes of determining the total amount raised. Issuers must consider whether previous or subsequent offerings should be integrated based on factors including timing, type of consideration, and manner of offering.

Rule 502: General Conditions to Regulation D Exemptions

Rule 502 establishes three critical conditions that apply to most Regulation D offerings: integration, information requirements, and limitations on resale.

Integration Doctrine (Rule 502(a))

The integration doctrine addresses when multiple securities offerings should be considered a single offering for purposes of applying Regulation D's requirements and limitations. The rule provides a safe harbor stating that offers and sales made more than six months before the start of a Regulation D offering, or more than six months after completion of a Regulation D offering, will not be integrated with the Regulation D offering, provided that during those six-month periods, the issuer makes no offers or sales of securities of the same or similar class.

The practical implication of integration is significant. If two offerings are integrated, they must be evaluated together to determine whether they satisfy Regulation D's requirements. For example, if an issuer conducts a Rule 506(b) offering without general solicitation, then conducts a second offering six weeks later using general solicitation, the two offerings may be integrated, potentially invalidating the first offering's exemption.

The 2020 amendments introduced a more flexible integration framework, replacing the rigid six-month safe harbor with a principles-based analysis that considers four factors: whether the sales are part of a single plan of financing, whether the sales involve issuance of the same class of securities, whether the sales are made at or about the same time, whether the same type of consideration is received, and whether the sales are made for the same general purpose.

Information Requirements (Rule 502(b))

Rule 502(b) establishes disclosure requirements for offerings that include non-accredited investors. When an issuer sells securities to non-accredited investors in a Rule 506(b) offering, the issuer must furnish specified financial and non-financial information to all purchasers a reasonable time before sale. The required information varies based on the size of the offering and the nature of the issuer.

For offerings up to $20 million, issuers must provide financial statements for the two most recent fiscal years, which need not be audited if obtaining audited statements would involve unreasonable effort or expense. For offerings exceeding $20 million, issuers must provide audited financial statements. Non-financial information requirements include a description of the issuer's business, properties, and management, as well as disclosure of the material terms of the securities being offered.

Importantly, Rule 506(c) offerings that include only accredited investors are not subject to these information requirements, though issuers must still take reasonable steps to verify that all purchasers are accredited. This creates a fundamental trade-off: Rule 506(b) allows non-accredited investors but requires disclosure, while Rule 506(c) permits general solicitation but requires verification and limits investors to accredited individuals and entities.

Limitations on Resale (Rule 502(d))

Securities acquired in a Regulation D offering are "restricted securities" under Rule 144, meaning they cannot be resold without registration or an applicable exemption. Rule 502(d) requires issuers to exercise reasonable care to ensure that purchasers are not underwriters, which typically involves including restrictive legends on certificates, issuing stop-transfer instructions to transfer agents, and obtaining written representations from purchasers regarding their investment intent.

The practical effect of these resale limitations is that investors in Regulation D offerings must hold their securities for an extended period (typically at least six months to one year under Rule 144) before they can resell them, and even then, resales are subject to volume limitations and manner of sale restrictions. Issuers must clearly disclose these limitations to investors before sale to ensure investors understand the illiquid nature of the investment.

Rule 503: Filing of Notice of Sales (Form D)

Rule 503 requires issuers to file a Form D notice with the SEC within 15 days after the first sale of securities in a Regulation D offering. Form D is a brief notice filing that includes basic information about the issuer, the offering, and the persons involved in the offering. The filing requirement applies to all Regulation D offerings, regardless of which specific rule the issuer relies upon.

Form D requires disclosure of the issuer's name, address, jurisdiction of incorporation, and industry classification, as well as information about the offering including the type of securities offered, the minimum investment amount, and the total offering amount. The form also requires identification of persons receiving sales commissions and persons involved in the offering, including executive officers, directors, and promoters.

Failure to file Form D does not automatically invalidate the exemption, but it can result in SEC enforcement actions and may be considered evidence of non-compliance in investor lawsuits. Many states also require Form D filing as a condition of claiming a state-level exemption, making timely filing essential for both federal and state compliance.

Rule 506(b): Private Placements Without General Solicitation

Rule 506(b) is the most widely used exemption under Regulation D, accounting for approximately 75% of all Regulation D offerings. The rule permits issuers to raise unlimited capital from an unlimited number of accredited investors and up to 35 non-accredited investors, provided the issuer does not engage in general solicitation or advertising.

Key Requirements of Rule 506(b)

The prohibition on general solicitation is the defining characteristic of Rule 506(b). The rule requires that all purchasers either have a pre-existing substantive relationship with the issuer or its representatives, or are sophisticated investors who, alone or with a purchaser representative, have sufficient knowledge and experience in financial and business matters to evaluate the merits and risks of the investment.

The pre-existing relationship requirement is not defined in the regulation itself, but SEC guidance and no-action letters provide clarity. A substantive relationship generally requires that the issuer or its representatives have sufficient information about the prospective investor to evaluate their financial circumstances and sophistication, and that this information was obtained through direct interaction over time, not merely through a questionnaire or brief conversation.

For non-accredited investors, Rule 506(b) imposes additional requirements. The issuer must reasonably believe that each non-accredited investor, either alone or with a purchaser representative, possesses sufficient knowledge and experience in financial and business matters to be capable of evaluating the merits and risks of the investment. Additionally, the issuer must provide specified disclosure documents to all non-accredited investors a reasonable time before sale.

Advantages of Rule 506(b)

Rule 506(b) offers several significant advantages for issuers with established investor networks. First, the rule permits inclusion of up to 35 sophisticated but non-accredited investors, providing flexibility for issuers who wish to include employees, friends, family members, or strategic partners who do not meet the wealth or income thresholds for accredited investor status.

Second, Rule 506(b) does not require verification of accredited investor status. The issuer need only have a "reasonable belief" that each purchaser is accredited, which can be satisfied through investor questionnaires and representations. This reduces compliance burden and administrative costs compared to Rule 506(c), which mandates documented verification.

Third, Rule 506(b) offerings benefit from federal preemption of state blue sky laws under Section 18 of the Securities Act. States cannot require registration or qualification of Rule 506(b) offerings, though they can require notice filings and collect filing fees. This preemption significantly simplifies multi-state offerings.

Limitations and Risks of Rule 506(b)

The primary limitation of Rule 506(b) is the prohibition on general solicitation, which restricts how issuers can market their offerings. Issuers cannot advertise the offering on public websites, social media platforms, or through mass email campaigns. They cannot host public webinars or seminars to promote the offering. They cannot issue press releases announcing the offering and inviting investment. These restrictions can significantly limit the pool of potential investors, particularly for first-time issuers or emerging managers without established networks.

The consequences of violating the general solicitation prohibition are severe. If an issuer engages in general solicitation while purporting to rely on Rule 506(b), the entire offering may lose its exemption, giving all investors rescission rights to demand return of their capital plus interest. The SEC may bring enforcement actions seeking penalties, disgorgement, and injunctions. In egregious cases, issuers and their principals may face bad actor disqualification, preventing them from relying on Regulation D exemptions for future offerings.

Rule 506(c): Private Placements With General Solicitation

Rule 506(c) was added to Regulation D in September 2013 pursuant to the JOBS Act. The rule permits issuers to engage in general solicitation and advertising to market their offerings, provided that all purchasers are accredited investors and the issuer takes reasonable steps to verify their accredited status.

Key Requirements of Rule 506(c)

The verification requirement is the defining feature of Rule 506(c). Unlike Rule 506(b), which permits issuers to rely on investor self-certification, Rule 506(c) requires issuers to take reasonable steps to verify that all purchasers are accredited investors. The rule provides several safe harbor methods of verification, including reviewing tax returns, W-2 forms, bank statements, credit reports, or obtaining written confirmation from registered broker-dealers, attorneys, or CPAs.

The reasonableness of verification steps depends on the facts and circumstances of each transaction. Factors the SEC considers include the nature of the purchaser and the type of accredited investor claim, the amount and type of information the issuer has about the purchaser, and the nature of the offering. For offerings conducted through online platforms or involving investors with whom the issuer has no prior relationship, more rigorous verification is typically required.

Advantages of Rule 506(c)

Rule 506(c) offers transformative marketing flexibility for issuers. Issuers can advertise their offerings on public websites, post about them on social media platforms like LinkedIn and Twitter, send email campaigns to purchased or cold lists, host public webinars and seminars, issue press releases announcing the offering, and conduct media interviews discussing the investment opportunity. This marketing freedom enables issuers to reach far larger pools of potential investors than would be possible under Rule 506(b)'s relationship-based model.

For issuers with strong marketing capabilities or those raising capital for the first time without established investor networks, Rule 506(c) can dramatically accelerate the capital raising process. The ability to leverage content marketing, paid advertising, public relations, and social media can generate hundreds or thousands of investor leads, far exceeding what most issuers could achieve through warm introductions alone.

Limitations and Risks of Rule 506(c)

The verification requirement creates significant administrative burden and compliance risk. Issuers must collect sensitive financial documents from all investors, review them for authenticity and sufficiency, and maintain detailed records of their verification procedures. For offerings with dozens or hundreds of investors, this process can consume substantial time and resources.

The verification requirement also creates friction in the investor experience. Many high-net-worth individuals are reluctant to share tax returns, bank statements, or other financial documents with issuers, particularly for smaller investment amounts. This friction can reduce conversion rates and extend the time required to close investments.

Additionally, Rule 506(c) offerings are limited to accredited investors only. Unlike Rule 506(b), which permits up to 35 sophisticated but non-accredited investors, Rule 506(c) provides no flexibility to include employees, friends, family members, or strategic partners who do not meet accredited investor thresholds.

Choosing Between Rule 506(b) and Rule 506(c)

The choice between Rule 506(b) and Rule 506(c) depends fundamentally on the issuer's investor network, marketing strategy, and willingness to implement verification procedures. The following decision framework can guide issuers in selecting the appropriate exemption:

Choose Rule 506(b) if:

  • You have an established investor network and can fill the offering through existing relationships
  • You want the flexibility to include up to 35 sophisticated but non-accredited investors
  • You prefer to avoid the administrative burden and investor friction of verification procedures
  • You are conducting a friends and family round or raising from a small group of known investors
  • You want to minimize compliance costs and administrative complexity

Choose Rule 506(c) if:

  • You are a first-time issuer without an established investor network
  • You want to leverage content marketing, paid advertising, and social media to generate investor leads
  • You are comfortable implementing verification procedures and collecting financial documents
  • All of your target investors are accredited and willing to provide verification documentation
  • You want maximum marketing flexibility and are willing to accept the verification burden in exchange

Many issuers find that Rule 506(b) works well for initial rounds where they are raising from known contacts, then transition to Rule 506(c) for later rounds when they want to expand their investor base through public marketing. Some issuers conduct simultaneous offerings under both rules, using Rule 506(b) for existing relationships and Rule 506(c) for new investors sourced through marketing.

State Blue Sky Law Coordination

While Rule 506 offerings benefit from federal preemption of state registration and qualification requirements, states retain authority to require notice filings, collect filing fees, and enforce anti-fraud provisions. Most states require issuers to file a Form D and pay a filing fee before or shortly after making sales to residents of that state. Filing fees typically range from $250 to $1,000 per state, with some states charging fees based on the amount raised from state residents.

Issuers must carefully track which states their investors reside in and ensure timely filing in each state. Failure to make required state filings can result in state enforcement actions, investor rescission rights under state law, and bad actor disqualification in some jurisdictions. Many issuers engage specialized blue sky filing services to manage multi-state compliance, particularly for offerings involving investors in numerous states.

Common Mistakes and How to Avoid Them

Mistake #1: Engaging in general solicitation while relying on Rule 506(b)

Many issuers inadvertently violate the general solicitation prohibition by posting offering details on public websites, discussing the offering in media interviews, or sending email blasts to non-targeted lists. To avoid this mistake, issuers should implement strict marketing controls, password-protect all offering materials, and ensure all communications are directed only to individuals with whom the issuer has pre-existing relationships.

Mistake #2: Failing to verify accredited investor status in Rule 506(c) offerings

Some issuers relying on Rule 506(c) collect investor self-certifications but fail to take reasonable steps to verify the accuracy of those certifications. To avoid this mistake, issuers should implement one of the safe harbor verification methods, maintain detailed documentation of their verification procedures, and engage legal counsel to review verification protocols before launching the offering.

Mistake #3: Missing Form D filing deadlines

Form D must be filed within 15 days after the first sale of securities. Many issuers miss this deadline, particularly when the first sale occurs quickly after launch. To avoid this mistake, issuers should prepare Form D in advance and establish clear procedures for filing immediately after the first investor wires funds.

Mistake #4: Failing to include restrictive legends and transfer restrictions

Securities sold in Regulation D offerings are restricted securities that cannot be freely resold. Issuers must include appropriate restrictive legends on certificates and obtain written investment representations from purchasers. To avoid this mistake, issuers should work with securities counsel to draft appropriate subscription agreements and stock certificates that include required legends and restrictions.

Mistake #5: Integrating multiple offerings inappropriately

Issuers sometimes conduct multiple offerings in close succession without considering whether they should be integrated for purposes of Regulation D. To avoid this mistake, issuers should consult with counsel before launching any offering to evaluate whether previous or planned future offerings should be integrated, and structure offerings with appropriate time gaps and factual distinctions to avoid integration.

Frequently Asked Questions

What is the difference between Rule 506(b) and Rule 506(c)?

Rule 506(b) prohibits general solicitation but allows up to 35 non-accredited investors and requires only reasonable belief of accredited status. Rule 506(c) permits general solicitation but requires all investors to be accredited and mandates documented verification of accredited status.

How do I verify accredited investor status under Rule 506(c)?

The rule provides several safe harbor methods including reviewing tax returns, W-2 forms, bank statements, or credit reports from the past two years, or obtaining written confirmation from a registered broker-dealer, attorney, or CPA who has verified the investor's accredited status within the past three months.

Can I include non-accredited investors in a Rule 506(b) offering?

Yes, Rule 506(b) permits up to 35 non-accredited investors, provided they are sophisticated (either alone or with a purchaser representative) and you provide them with specified disclosure documents before they invest.

Do I need to file Form D for every Regulation D offering?

Yes, Form D must be filed within 15 days after the first sale of securities in any Regulation D offering, regardless of which specific rule you rely upon.

What happens if I accidentally engage in general solicitation in a Rule 506(b) offering?

Engaging in general solicitation while relying on Rule 506(b) can invalidate the entire offering exemption, giving investors rescission rights and exposing you to SEC enforcement actions. If you realize you have engaged in general solicitation, consult securities counsel immediately to evaluate remediation options.

Can I switch from Rule 506(b) to Rule 506(c) mid-offering?

Switching exemptions mid-offering creates integration risk and compliance complexity. If you want to add general solicitation to your marketing strategy, it is generally better to close the Rule 506(b) offering, wait an appropriate period, and then launch a new Rule 506(c) offering.

Are Regulation D offerings exempt from state securities laws?

Rule 506 offerings are exempt from state registration and qualification requirements, but states can still require notice filings, collect filing fees, and enforce anti-fraud provisions. You must comply with notice filing requirements in each state where you have investors.

How long must investors hold Regulation D securities before they can resell them?

Securities acquired in Regulation D offerings are restricted securities under Rule 144. Generally, investors must hold the securities for at least six months (for reporting companies) or one year (for non-reporting companies) before they can resell them, and even then resales are subject to volume limitations and manner of sale restrictions.

What is a "pre-existing substantive relationship" for purposes of Rule 506(b)?

A pre-existing substantive relationship generally requires that you or your representatives have sufficient information about the prospective investor to evaluate their financial circumstances and sophistication, obtained through direct interaction over time. A brief conversation or completion of a questionnaire is typically insufficient.

Can I use social media to market a Rule 506(c) offering?

Yes, Rule 506(c) explicitly permits general solicitation, including social media marketing. However, you must still comply with anti-fraud rules, which require that all statements be truthful and not misleading, and you must verify that all purchasers are accredited investors.

What is the "bad actor" disqualification rule?

Rule 506(d) disqualifies issuers from relying on Rule 506 if certain "bad actors" are involved in the offering, including the issuer, its predecessors, affiliated issuers, directors, executive officers, general partners, managing members, and certain compensated solicitors. Bad actor events include criminal convictions, SEC enforcement actions, and certain regulatory orders.

Do I need audited financial statements for a Rule 506 offering?

Only if you are including non-accredited investors in a Rule 506(b) offering and the offering size exceeds $20 million. For offerings up to $20 million with non-accredited investors, audited financials are required only if they are available without unreasonable effort or expense. Rule 506(c) offerings with only accredited investors have no financial statement requirements.
