What is the difference between Rule 506(b) and Rule 506(c)? Both are exemptions under Regulation D that let a company raise capital privately without registering the offering with the SEC. Rule 506(b) prohibits general solicitation and advertising, and in exchange permits sales to as many as 35 non-accredited purchasers. Rule 506(c) permits an issuer to advertise an offering broadly, and in exchange requires that every purchaser be an accredited investor whose status the issuer has taken reasonable steps to verify.
One rule buys silence. The other buys paperwork. That single trade explains why an investor can read about one private real estate offering on a public website and hear about another only through an introduction, and why the second conversation ends with a questionnaire while the first ends with a request for tax documents. This guide covers what each rule permits, where verification actually differs, why a sponsor picks one, and what stays identical in both. The structure sitting underneath either exemption is described in how a commercial real estate fund is organized and paid.
Key Takeaways
- Rule 506(b) prohibits general solicitation and advertising but permits sales to as many as 35 non-accredited purchasers who meet a sophistication standard.
- Rule 506(c) permits an issuer to broadly solicit and generally advertise, and requires that every purchaser be a verified accredited investor.
- Verification is the practical dividing line: a 506(b) issuer may rely on reasonable belief, while a 506(c) issuer must take affirmative, documented steps.
- Selling to non-accredited investors under 506(b) triggers specific disclosure obligations, including financial statements, which is why many sponsors decline to do it.
- Both exemptions require a Form D notice within 15 days after the first sale, produce restricted securities, and carry bad actor disqualification provisions.
- An exemption is a filing category rather than an SEC review, so neither rule says anything about whether an offering is sound.

What Rule 506(b) Permits and Prohibits
Rule 506(b) is the traditional private placement exemption. It prohibits general solicitation and general advertising, which means the offering can be discussed only with people the issuer already knows through a preexisting relationship. In exchange, it permits sales to an unlimited number of accredited investors plus a limited number of non-accredited purchasers.
The SEC's guidance on private placements under Rule 506(b) states the conditions directly: no general solicitation or advertising to market the securities, and securities may not be sold to more than 35 non-accredited investors. The rule text frames that limit as a count of purchasers in any 90 calendar day period, and it attaches a quality test on top of the quantity test. Each non-accredited purchaser, alone or with a purchaser representative, must have sufficient knowledge and experience in financial and business matters to be capable of evaluating the merits and risks of the investment.
Admitting even one non-accredited purchaser changes the issuer's obligations substantially. The SEC guidance provides that companies must give non-accredited investors disclosure documents containing information generally similar to what a Regulation A or registered offering would provide, including specified financial statements that in some cases must be certified or audited by an accountant. The issuer should also be available to answer questions from those prospective purchasers.
That cost explains a pattern investors notice and misread. Many sponsors relying on 506(b) still sell only to accredited investors, not because the rule requires it, but because preparing an audited disclosure package for a handful of subscriptions is expensive and creates a second class of investor relations work. The permission to include non-accredited purchasers is real, and it is used far less often than the rule allows.
What Rule 506(c) Permits and Requires
Rule 506(c) is the exemption that lets a private issuer speak publicly. The SEC states that Rule 506(c) permits issuers to broadly solicit and generally advertise an offering. The condition attached is absolute rather than graduated: all purchasers must be accredited investors, and the issuer must take reasonable steps to verify that status.
General solicitation is a wider category than most people assume, which matters because crossing into it is what makes the exemption necessary. The SEC's compliance guide on eliminating the prohibition against general solicitation names advertisements published in newspapers and magazines, public websites, communications broadcast over television and radio, and seminars where attendees were invited by general solicitation. A public post describing an offering, a conference presentation open to the general public, and an unrestricted page on a website all fall inside that description.
The consequence runs one direction and it is worth stating plainly. Once an offering has been generally solicited, Rule 506(b) is no longer available for it, because the absence of general solicitation is a condition of that exemption rather than a preference. A sponsor that advertises first and decides later that it would rather accept a non-accredited investor has already spent the option.
What the advertising permission does not do is change the character of the security. A 506(c) offering is still an unregistered private placement. It is not reviewed by the SEC, the antifraud provisions of the securities laws apply to every statement made in the advertising, and the interest a purchaser receives is a restricted security. Visibility and registration are separate things, and an offering that appears in public view has cleared a filing condition rather than a quality bar.
Verification Is the Real Difference
Verification is where the two rules separate in practice. A 506(b) issuer may generally rely on a reasonable belief that a purchaser qualifies, which usually takes the form of a completed investor questionnaire. A 506(c) issuer has to take affirmative steps, and the standard is an objective one rather than a matter of good faith.
The SEC describes the requirement as a principles-based method that calls for an objective determination by the issuer as to whether the steps taken are reasonable in the context of the particular facts and circumstances. Three factors drive that determination: the nature of the purchaser and the type of accredited investor the purchaser claims to be, the amount and type of information the issuer already has about the purchaser, and the nature of the offering itself.
Rule 506(c) also sets out a non-exclusive list of methods that satisfy the requirement, and these are what an investor actually encounters at subscription. For the income test, reviewing IRS forms reporting income for the two most recent years, such as a Form W-2, Form 1099, Schedule K-1, or Form 1040, together with a written representation about the current year. For the net worth test, reviewing documentation dated within the prior three months, including bank or brokerage statements and appraisals for assets and a consumer report for liabilities, with a written representation that all liabilities have been disclosed. Alternatively, written confirmation from a registered broker-dealer, an SEC-registered investment adviser, a licensed attorney in good standing, or a certified public accountant in good standing. A separate path covers certain investors who purchased in the issuer's earlier Rule 506(b) offerings, and a previously verified investor may provide a written representation that remains usable for five years.
The staff has also addressed minimum investment size. In a response dated March 12, 2025, the SEC's Division of Corporation Finance described a high minimum investment amount as a relevant factor in verifying accredited investor status, where the purchaser represents both that it is accredited and that the investment is not financed in whole or in part by a third party for that purpose, and the issuer has no actual knowledge of facts indicating otherwise. Who qualifies in the first place is set by rule rather than by any sponsor, and the thresholds are covered in the guide to what qualifies someone as an accredited investor in commercial real estate.
Why a Sponsor Chooses One Rule Over the Other
The choice is a trade between reach and friction, and both sides of it are ordinary business decisions rather than signals about quality. Rule 506(b) preserves flexibility about who may purchase and keeps the subscription process lighter. Rule 506(c) permits public discussion of an offering and pays for that permission with a verification process applied to every single purchaser.
A sponsor with a long investor list and a habit of raising capital through relationships gives up little by staying inside 506(b). The offering is described only to people already known, the paperwork at closing is a questionnaire rather than a document review, and a long-standing investor who no longer meets the accreditation thresholds can still participate if the sponsor is willing to carry the disclosure obligations that come with that.
A sponsor that wants to publish, present publicly, or describe an offering on an open website needs 506(c), and accepts three costs in return. Every purchaser must be accredited, so the non-accredited category disappears entirely. Every purchaser must be verified, which means either collecting sensitive financial documents or routing the investor to a third party who will issue a letter. And every public statement about the offering is subject to the antifraud provisions, which raises the stakes on marketing language considerably.
None of this tells an investor anything about the underlying assets, the fee structure, or the sponsor's discipline. The exemption governs how the offering may be marketed and who may buy it. Whether the vehicle is a single-asset deal or a pooled one is a separate question entirely, addressed in how a syndication and a fund differ for a passive investor, and the two choices are independent of each other.
What Does Not Change Under Either Rule
A surprising amount is identical on both sides of the line, and the shared requirements are often more consequential to an investor than the difference. Both exemptions produce an unregistered offering of restricted securities, both require the same notice filing, both preempt state registration while leaving state notice obligations intact, and both leave every substantive question to the investor.
Four specifics carry across. A company relying on either exemption is required to file a notice with the Commission on Form D within 15 days after the first sale of securities in the offering, and that filing is a notice rather than an application. Purchasers receive restricted securities, which cannot be freely resold without registration or another exemption, so illiquidity is a feature of both. The Securities Act provides federal preemption from state registration and qualification for Rule 506 offerings, though states retain authority to require notice filings and collect fees. And both are subject to bad actor disqualification provisions, which can put the exemption out of reach for an issuer whose covered persons have certain disciplinary histories.
The most important shared fact is what neither rule does. No one at the SEC reads the offering documents, evaluates the properties, checks the projections, or forms a view on whether the terms are fair. An exemption is a filing category. That leaves the entire substance of the decision with the investor, which is why the diligence described in what the passive investor position actually involves does not get any lighter because an offering was permitted to advertise.
For an investor comparing two offerings, then, the useful reading of the exemption is narrow and practical. It predicts how the offering was found, what documents will be requested before a subscription is accepted, and whether anyone outside the accredited category can participate. It predicts nothing else.

Frequently Asked Questions
Q: Can a Rule 506(b) offering be advertised on a website or social media?
A: No. The absence of general solicitation is a condition of the exemption, and the SEC's examples of general solicitation include public websites, newspaper and magazine advertisements, television and radio communications, and seminars whose attendees were invited by general solicitation. A public post describing the offering would put the exemption at risk for that offering rather than simply breaking a guideline.
Q: Can a non-accredited investor participate in a Rule 506(c) offering?
A: No. Rule 506(c) requires that all purchasers be accredited investors, with no exception for sophistication or for a preexisting relationship. Rule 506(b) is the exemption that permits non-accredited purchasers, capped at 35 and subject to a sophistication standard, and admitting them triggers specific disclosure requirements including financial statements.
Q: What counts as reasonable steps to verify accredited investor status?
A: The standard is principles-based and objective, weighing the nature of the purchaser, the information the issuer already holds, and the nature of the offering. The rule lists non-exclusive safe methods, including reviewing IRS income forms for the two most recent years, reviewing asset and liability documentation dated within the prior three months, or obtaining written confirmation from a registered broker-dealer, an SEC-registered investment adviser, a licensed attorney, or a CPA.
Q: Does a Form D filing mean the SEC reviewed or approved the offering?
A: No. Form D is a notice filed within 15 days after the first sale, not an application and not a review. No one at the Commission evaluates the assets, the projections, or the terms. That is why the exemption an offering relies on says nothing about its quality, and why the substantive work stays with the investor and their own advisors.
