Rule 506(b) vs 506(c): Key Differences for Issuers
Rule 506(b) and 506(c) are the two most popular Regulation D exemptions for raising private capital. This guide breaks down their differences so you can choose the right one for your offering.
This article is for informational and educational purposes only and does not constitute financial, legal, investment, or tax advice.
- Rule 506(b) prohibits general solicitation but allows up to 35 non-accredited investors alongside unlimited accredited investors, with self-certification of accredited status.
- Rule 506(c) permits general solicitation and public advertising but requires all investors to be accredited investors with independent verification.
- Both rules allow unlimited capital raises, preempt state registration, and require a Form D filing with the SEC.
- Choose 506(b) when you have a strong existing investor network and want operational simplicity. Choose 506(c) when you need to reach new investors through public channels.
- The decision often comes down to a trade-off between marketing flexibility (506(c)) and lower compliance overhead (506(b)).
Overview of Rule 506(b) and 506(c)
Rules 506(b) and 506(c) are both part of Regulation D under the Securities Act of 1933. They are the two most widely used exemptions for private capital raises in the United States, collectively accounting for the vast majority of the more than $2.7 trillion raised through Reg D offerings annually. Both allow issuers to raise an unlimited amount of capital without registering securities with the SEC, and both preempt state “blue sky” registration requirements.
Despite these similarities, 506(b) and 506(c) operate under fundamentally different frameworks when it comes to how issuers find investors and how they confirm investor eligibility. Understanding these differences is essential for fund managers, SPV sponsors, startup founders, and real estate syndicators who need to select the right exemption for their offering.
Rule 506(b) has been available since Regulation D was adopted in 1982. It is the older, more established exemption and remains the most heavily used by a wide margin. Rule 506(c) was introduced by the JOBS Act in 2012 and became effective in September 2013. It was designed to modernize private capital formation by allowing issuers to publicly market their offerings—a previously prohibited practice under all Reg D exemptions.
General Solicitation Explained
The most consequential difference between 506(b) and 506(c) is the treatment of general solicitation. This single distinction shapes everything from how you find investors to how you structure your marketing, and it is the primary factor driving most issuers’ choice between the two rules.
What Counts as General Solicitation
General solicitation refers to any broadly distributed communication used to attract investors to a securities offering. The SEC and courts have interpreted this concept broadly. Examples include:
- Advertisements in newspapers, magazines, websites, or social media platforms
- Mass emails or cold outreach to potential investors with whom the issuer has no prior relationship
- Public seminars, conferences, or “demo day” presentations where investment opportunities are discussed
- Television, radio, or podcast advertisements promoting an offering
- Listings on investment platforms or crowdfunding-style websites that are open to the public
Under Rule 506(b), all of these activities are prohibited. An issuer relying on 506(b) cannot use any form of general solicitation or general advertising to attract investors. Under Rule 506(c), all of these activities are permitted—issuers can openly market their offerings through any channel they choose.
The Pre-Existing Relationship Standard
Because 506(b) prohibits general solicitation, issuers must rely on pre-existing, substantive relationships to identify potential investors. The SEC has clarified that a “pre-existing relationship” means the issuer (or its broker-dealer) had an existing relationship with the investor before the offering began. A “substantive” relationship means the issuer has enough information about the investor to reasonably evaluate their financial sophistication and ability to bear the investment’s risks.
In practice, this means 506(b) issuers typically raise capital from:
- Personal and professional contacts of the founders or sponsors
- Existing investors in prior funds or vehicles
- Investors introduced through registered broker-dealers who have vetted the relationship
- Members of investor networks or groups where membership is substantively screened (not just open registration)
This relationship requirement is one of the most commonly misunderstood aspects of 506(b). Simply meeting someone at a conference and immediately discussing a deal does not establish a pre-existing relationship. The relationship must predate the offering, and the issuer must have a basis for evaluating the investor’s sophistication.
Investor Verification Requirements
The second major difference between 506(b) and 506(c) concerns how issuers confirm that their investors qualify as accredited investors. This distinction has significant operational and cost implications.
Self-Certification Under 506(b)
Under Rule 506(b), issuers may rely on investor self-certification to establish accredited status. In practice, this typically involves:
- An accredited investor questionnaire included in the subscription documents
- A checkbox or representation where the investor affirms they meet one or more accredited investor criteria
- The investor’s signature on subscription agreements containing accredited investor representations
No independent verification is required. The issuer does not need to review tax returns, bank statements, or other financial documents. This self-certification approach is significantly simpler and faster, which is one reason 506(b) remains so popular.
However, self-certification carries risk. If an investor falsely claims accredited status and later challenges the investment, the issuer’s exemption could be jeopardized if it had reason to doubt the investor’s representation and failed to investigate further.
Reasonable Steps Under 506(c)
Under Rule 506(c), issuers must take “reasonable steps” to independently verify that every investor is an accredited investor. Self-certification alone is not sufficient. The SEC has provided a non-exclusive list of acceptable verification methods:
- Income verification: Reviewing IRS forms such as W-2s, 1099s, or tax returns for the two most recent years, combined with a written representation that the investor reasonably expects to meet the income threshold in the current year.
- Net worth verification: Reviewing bank statements, brokerage statements, certificates of deposit, tax assessments, or appraisal reports, combined with a consumer credit report to check for liabilities.
- Third-party confirmation: Obtaining a written confirmation from a registered broker-dealer, SEC-registered investment adviser, licensed CPA, or attorney that the professional has taken reasonable steps to verify the investor’s accredited status within the prior three months.
- Existing investor recertification: For investors who previously invested in the issuer’s offerings and were verified as accredited at that time, obtaining a written certification that their status has not changed.
Many issuers use third-party verification services to streamline this process, but it still adds time, cost, and friction to the subscription process. Some investors are reluctant to share sensitive financial documents, which can reduce conversion rates.
Side-by-Side Comparison Table
The following table summarizes the core differences between Rule 506(b) and Rule 506(c):
| Feature | Rule 506(b) | Rule 506(c) |
|---|---|---|

| State preemption | Yes (covered security) | Yes (covered security) |
| Form D filing | Required within 15 days | Required within 15 days |
| Bad actor disqualification | Yes | Yes |
| Typical use case | Funds, SPVs, startups raising from known investors | Online platforms, public fundraising, broad distribution |
Which Rule Should You Choose?
The right exemption depends on your specific situation. Here are the key factors to evaluate:
Choose Rule 506(b) if:
- You have an established network of investors and strong pre-existing relationships.
- You want to include a small number of non-accredited but sophisticated investors (such as friends, family, or trusted advisors).
- You prefer a simpler subscription process with self-certification rather than full verification.
- You do not need to publicly advertise the offering.
- Operational simplicity and lower compliance costs are priorities.
Choose Rule 506(c) if:
- You need to reach investors beyond your existing network through advertising, social media, or online platforms.
- You are comfortable limiting participation to accredited investors only.
- You have the infrastructure (or a third-party provider) to handle accredited investor verification efficiently.
- Your offering benefits from broad public visibility—for example, a fund with a compelling track record that could attract capital through marketing.
- You operate an online investment platform or syndication model where public marketing is essential to the business.
Many issuers start with 506(b) for their initial raises, leveraging existing relationships and keeping the process straightforward. As their track record grows and they need access to a wider pool of investors, they transition to 506(c) for subsequent offerings. Some issuers run both types simultaneously for different vehicles or fund series.
Practical Considerations for Issuers
Cost and Timeline Differences
The verification requirements under 506(c) add both direct and indirect costs. Direct costs include fees for third-party verification services, which typically range from $30 to $100 per investor. Indirect costs include longer subscription timelines (investors need time to gather and submit documentation), potential investor drop-off during the verification process, and the administrative overhead of managing verification workflows.
Under 506(b), the subscription process is faster because self-certification can be completed as part of the standard subscription agreement. There are no additional verification fees, and investors are not asked to produce sensitive financial documents.
For the Form D filing itself, the process is identical regardless of which rule you choose. Both require filing with the SEC within 15 days of the first sale, and both must indicate the specific exemption relied upon. For a step-by-step walkthrough, see our guide on how to file Form D.
Marketing and Distribution Strategy
The general solicitation distinction fundamentally shapes your distribution strategy. Under 506(b), investor outreach is inherently personal and relationship-driven. Your “marketing” is limited to one-on-one conversations, small group meetings with pre-qualified contacts, and introductions through broker-dealers or existing investors.
Under 506(c), you can build a full marketing funnel: content marketing, paid advertising, social media campaigns, webinars, conference presentations, and listings on investment platforms. This is particularly powerful for issuers who want to build a brand around their investment offerings or who operate in markets where investor education and visibility drive deal flow.
However, the ability to advertise under 506(c) does not mean anything goes. All marketing materials must still comply with securities laws—they cannot contain misleading statements, must present balanced information about risks and returns, and should be reviewed by securities counsel. The SEC has brought enforcement actions against issuers whose 506(c) advertising crossed the line into fraud or misrepresentation.

Frequently Asked Questions
Can I switch from Rule 506(b) to 506(c) during an offering?
Switching mid-offering is risky and generally not recommended. If you began an offering under 506(b) without general solicitation and then switch to 506(c), you must ensure that all investors—including those who subscribed under the 506(b) phase—are verified accredited investors. Any non-accredited investors who participated during the 506(b) phase would need to be excluded, which may not be legally or practically feasible. The safer approach is to complete the 506(b) offering, then launch a new offering under 506(c) with proper verification procedures in place from the start.
Does choosing 506(c) mean my Form D filing will look different?
Yes. When filing Form D, you must indicate whether you are relying on Rule 506(b) or Rule 506(c). This selection is publicly visible on the SEC’s EDGAR database. Beyond that checkbox, the form itself collects the same information under both rules: issuer details, offering size, amounts sold, number of investors, and use of sales commissions. You can track these filings and see how other issuers are splitting between 506(b) and 506(c) using SPV Flow’s data tools.
What happens if I accidentally engage in general solicitation under 506(b)?
Engaging in general solicitation under a 506(b) offering can jeopardize the entire exemption. If the SEC determines that general solicitation occurred, the offering may lose its exemption status, meaning the securities were sold in violation of federal registration requirements. This exposes the issuer to potential rescission claims from investors (the right to get their money back), SEC enforcement action, and state-level penalties. Common inadvertent solicitation pitfalls include posting about an offering on social media, discussing deal specifics at public events, or sending offering materials to contacts without a pre-existing relationship.
Are there third-party services that handle 506(c) accredited investor verification?
Yes. Several services specialize in verifying accredited investor status for 506(c) offerings. These platforms typically review financial documents (tax returns, bank statements, brokerage statements) or obtain third-party professional letters (from CPAs, attorneys, or registered investment advisers) on behalf of the issuer. Using a reputable third-party verification service strengthens the issuer’s position that “reasonable steps” were taken, as the SEC has acknowledged that third-party verification is one of the accepted methods. Costs generally range from $30 to $100 per investor, depending on the provider and volume.
Which rule do most issuers choose—506(b) or 506(c)?
Rule 506(b) remains significantly more popular by both filing count and total capital raised. According to SEC data, approximately 90% of Regulation D offerings rely on Rule 506(b). The primary reasons are the lower compliance burden (self-certification vs. verification), the ability to include non-accredited investors, and the fact that many issuers have sufficient existing networks to fill their raises without advertising. However, 506(c) adoption has been growing steadily, particularly among online investment platforms, real estate syndicators, and fund managers who prioritize broad distribution and investor acquisition through digital channels.
