506(b) vs. 506(c): The Complete 2026 Guide for Capital Raisers
Rule 506(b) and Rule 506(c) are both Regulation D exemptions that let you raise unlimited capital without SEC registration. They differ in one fundamental tradeoff: 506(b) restricts how you find investors but simplifies verification; 506(c) lets you advertise freely but requires you to prove every investor is accredited. This guide explains both exemptions, compares them side by side, and helps you choose the right one for your raise.
The quick comparison
Both Rule 506(b) and Rule 506(c) are exemptions under Regulation D of the Securities Act of 1933. Both allow an issuer to raise an unlimited amount of capital from investors without registering the offering with the SEC. Both require the issuer to file a Form D with the SEC after the first sale and to comply with applicable state Blue Sky notice filing requirements.
The difference is a single tradeoff:
| Rule 506(b) | Rule 506(c) | |
|---|---|---|
| The tradeoff | Cannot advertise the offering | Can advertise the offering |
| The price of the tradeoff | Simpler investor verification | Must verify every investor’s accredited status |
Every other difference between the two exemptions flows from this single structural choice. The rest of this guide unpacks what that means in practice — for your marketing, your compliance burden, your legal costs, and your timeline.
What is Rule 506(b)?
Rule 506(b) is the older and more commonly used of the two Regulation D exemptions. It has been available since 1982 and is the exemption most private placements have relied on for over four decades.
Under 506(b), an issuer may raise an unlimited amount of capital from an unlimited number of accredited investors, plus up to 35 non-accredited investors who meet a sophistication standard. The issuer may not use general solicitation or general advertising to market the offering. Instead, the issuer may only offer securities to investors with whom the issuer or its placement agents have a pre-existing, substantive relationship.
Accredited investors in a 506(b) offering self-certify their status. The issuer is not required to independently verify that the investor meets the accredited investor thresholds. The investor checks a box on the Subscription Agreement or Investor Questionnaire attesting that they qualify, and the issuer is entitled to rely on that representation unless the issuer has reason to believe it is false.
Key features of Rule 506(b)
- No general solicitation or advertising permitted
- Unlimited accredited investors
- Up to 35 non-accredited investors (must meet sophistication standard)
- Investor self-certification of accredited status
- Pre-existing, substantive relationship required with all offerees
- Form D filing required within 15 days of first sale
- State Blue Sky notice filings required
What is Rule 506(c)?
Rule 506(c) was created by the JOBS Act of 2012 and became effective on September 23, 2013. It was designed to modernize capital formation by allowing issuers to publicly market their offerings while maintaining investor protection through mandatory verification.
Under 506(c), an issuer may raise an unlimited amount of capital from accredited investors only. No non-accredited investors are permitted under any circumstances. In exchange for this restriction, the issuer is permitted to use general solicitation and general advertising — meaning the issuer can market the offering publicly through social media, webinars, online platforms, conferences, advertisements, and any other channel.
The critical compliance requirement is verification. The issuer must take “reasonable steps to verify” that each investor is accredited. Self-certification alone is not sufficient. The SEC has provided four non-exclusive safe harbor verification methods, and third-party verification services have emerged to handle the process at scale.
Key features of Rule 506(c)
- General solicitation and advertising permitted
- Accredited investors only — no non-accredited investors
- Issuer must take reasonable steps to verify accredited status
- No pre-existing relationship requirement
- Form D filing required within 15 days of first sale
- State Blue Sky notice filings required

General solicitation: what it means in practice
The general solicitation restriction under 506(b) is the single most misunderstood rule in private placement law. Sponsors violate it constantly, usually without knowing it.
What counts as general solicitation
General solicitation is any communication that offers securities to the public at large or to any person with whom the issuer does not have a pre-existing, substantive relationship. The SEC and courts have interpreted this broadly. The following are all forms of general solicitation:
- Social media posts mentioning the offering (LinkedIn, Instagram, Facebook, X/Twitter)
- Webinars or seminars open to the general public that discuss the offering
- Websites or landing pages that describe the offering terms
- Email blasts to purchased or rented mailing lists
- Advertisements in any medium (print, digital, podcast, radio)
- Cold calls or cold emails to people the issuer has not previously met
- Online investment platforms that display the offering to unscreened users
What “pre-existing, substantive relationship” means
For 506(b), every person who receives an offer must have a pre-existing, substantive relationship with the issuer or its agents before the offering begins. “Pre-existing” means the relationship was established before the offering commenced — not in connection with it. “Substantive” means the issuer (or its broker-dealer, if one is involved) has enough information about the person to evaluate their financial circumstances and sophistication.
A name on a mailing list is not a substantive relationship. A connection on LinkedIn is not a substantive relationship. A business card collected at a conference is not a substantive relationship. A long-standing client, a business partner, a personal friend, or a person the issuer has known professionally for years — those are substantive relationships.
Why this matters
If a 506(b) issuer engages in general solicitation — even inadvertently — the exemption is potentially lost. The offering becomes unregistered, and every investor has a potential rescission claim. This is why 506(c) was created: to give issuers who need to market broadly a lawful path to do so.
Accredited investor verification under 506(c)
The verification requirement is the compliance cost of choosing 506(c). Unlike 506(b), where investors simply check a box, 506(c) requires the issuer to take “reasonable steps to verify” that each investor meets the accredited investor definition. The SEC has provided four non-exclusive safe harbor methods.
Safe harbor verification methods
| Method | What it requires |
|---|---|
| Income verification | Review IRS forms (W-2, 1099, K-1, tax returns) for the two most recent years showing income exceeding $200,000 (individual) or $300,000 (joint), plus a reasonable expectation of reaching the same level in the current year |
| Net worth verification | Review bank statements, brokerage statements, tax assessments, appraisal reports, and credit reports to confirm net worth exceeding $1 million (excluding primary residence) |
| Third-party confirmation | Obtain a written confirmation from a registered broker-dealer, SEC-registered investment adviser, licensed attorney, or CPA that the professional has taken reasonable steps to verify the investor’s accredited status within the prior three months |
| Existing verification | If the investor was previously verified as accredited in a prior offering by the same issuer, the issuer may rely on that verification if the investor self-certifies that their status has not changed |
In practice, most 506(c) issuers use either the third-party confirmation method or a specialized verification service. Services like Verify Investor, Parallel Markets, and others charge $30 to $75 per investor and handle the document collection, review, and written confirmation. This removes the verification burden from the issuer and creates a clean compliance record.
Non-accredited investors and 506(b)
One feature unique to 506(b) is the ability to accept up to 35 non-accredited investors. This is sometimes a decisive factor for sponsors whose investor base includes family members or friends who do not meet the accredited investor thresholds.
However, accepting non-accredited investors under 506(b) triggers additional disclosure requirements. The SEC requires that non-accredited investors receive disclosure documents “of the type that would be required in a Regulation A offering” — which means substantially more detailed financial and business disclosures than what most PPMs contain by default. In practice, this makes the documents longer and the engagement more expensive.
Most experienced securities counsel advise sponsors to limit their 506(b) offerings to accredited investors only, even though the rule permits non-accredited participation. The incremental cost and risk of the additional disclosure requirements rarely justify the benefit of accepting a small number of non-accredited investors.
Cost differences between the two exemptions
The legal cost of preparing a 506(b) and a 506(c) offering is substantially the same. The PPM, Subscription Agreement, Operating Agreement, Investor Questionnaire, Form D filing, and state Blue Sky filings are structurally similar regardless of which exemption is chosen. A specialist flat-fee firm typically charges the same flat fee for either exemption.
The cost differences emerge after document delivery:
| Cost element | 506(b) | 506(c) |
|---|---|---|
| PPM drafting | $12,000 – $25,000 (flat fee) | $12,000 – $25,000 (flat fee) |
| Investor verification | $0 (self-certification) | $30 – $75 per investor (third-party service) |
| Marketing costs | $0 (no advertising permitted) | Variable (advertising, platform fees, content) |
| Ongoing compliance | Minimal | Verification for each new investor throughout offering |

Which exemption is right for your raise?
The right exemption depends on three questions:
1. Can you fill the raise from your existing network?
If your existing relationships — personal, professional, and business contacts — are sufficient to fill the raise, 506(b) is almost always the better choice. You avoid the verification burden and cost, you maintain the option to accept a small number of non-accredited investors if needed, and the compliance profile is simpler. Most first-time sponsors raising $500,000 to $5 million fall into this category.
2. Do you need to reach investors you do not already know?
If you need to market the offering publicly — through social media, online platforms, conferences, or any form of advertising — 506(c) is the only lawful option. Any form of general solicitation under 506(b) jeopardizes the entire exemption. Sponsors raising larger amounts ($10 million and above), sponsors in markets where their personal network is insufficient, and sponsors using online fundraising platforms typically need 506(c).
3. Are any of your likely investors non-accredited?
If friends or family members who do not meet the accredited investor thresholds will invest, 506(b) is the only option. 506(c) does not permit any non-accredited investors under any circumstances. Keep in mind that accepting non-accredited investors under 506(b) triggers additional disclosure requirements and cost.
The practical default. For sponsors raising $500,000 to $10 million from people they already know, 506(b) is the standard starting point. For sponsors who need to market publicly or who are raising through online platforms, 506(c) is the correct choice. For sponsors who are unsure, a 15-minute call with a securities attorney can resolve the question definitively.
Can you switch from 506(b) to 506(c)?
This is one of the most frequently asked questions in private placement law, and the answer is not simple.
Technically, nothing in Regulation D prohibits an issuer from amending its offering to rely on a different exemption. In practice, switching from 506(b) to 506(c) mid-offering creates serious legal risk because of the integration doctrine.
The SEC’s integration analysis asks whether two purportedly separate offerings are actually a single offering. If a sponsor begins under 506(b), then later conducts general solicitation under 506(c), the SEC could determine that the entire offering — including the 506(b) period — was conducted with general solicitation, thereby destroying the 506(b) exemption retroactively. Every investor who purchased during the 506(b) period would then have a rescission claim.
The safest approach for a sponsor who wants to switch is to terminate the 506(b) offering completely, observe a reasonable waiting period (the SEC has adopted a 30-day safe harbor for offerings separated by at least 30 days that meet certain conditions), and commence a new 506(c) offering as a separate transaction.
Switching mid-stream without experienced securities counsel reviewing the specific facts is not recommended.

Frequently asked questions
What is the difference between 506(b) and 506(c)?
Rule 506(b) and Rule 506(c) are both exemptions under Regulation D of the Securities Act that allow issuers to raise unlimited capital without SEC registration. The core difference is the tradeoff between marketing and investor verification. 506(b) prohibits general solicitation and advertising but allows up to 35 non-accredited investors and requires only investor self-certification of accredited status. 506(c) permits general solicitation and advertising but requires that all investors be accredited and that the issuer take reasonable steps to verify each investor’s accredited status independently.
Can I advertise my offering under 506(b)?
No. Rule 506(b) prohibits general solicitation and general advertising. The issuer may only offer securities to investors with whom the issuer or its agents have a pre-existing, substantive relationship. This means no public advertising, no social media posts promoting the offering, no webinars open to the general public, and no online platforms that solicit investors broadly. The pre-existing relationship must be substantive — not merely a name on a mailing list — and must be established before the offering begins.
What does “reasonable steps to verify” mean under 506(c)?
Under Rule 506(c), the issuer must take reasonable steps to verify that each investor is an accredited investor. The SEC has identified four non-exclusive safe harbor methods for verifying income or net worth: reviewing tax returns for the two most recent years; reviewing bank, brokerage, or other asset statements; obtaining a written confirmation from a registered broker-dealer, SEC-registered investment adviser, licensed attorney, or CPA; or relying on an existing verification if the investor was previously verified and self-certifies that their status has not changed. Third-party verification services can handle this process for a per-investor fee.
Can non-accredited investors participate in a 506(c) offering?
No. Rule 506(c) requires that all investors in the offering be accredited investors. There is no exception. This is the tradeoff for being permitted to use general solicitation and advertising: the issuer gains the ability to market broadly but loses the ability to accept any non-accredited investors. If a non-accredited investor is discovered after closing, the exemption may be lost for the entire offering, creating rescission liability for every investor.
Which is better for a first-time capital raise, 506(b) or 506(c)?
For most first-time capital raisers, Rule 506(b) is the more practical choice. First-time sponsors typically raise from their existing network — friends, family, business contacts, and professional relationships — which satisfies the pre-existing relationship requirement. 506(b) also avoids the cost and administrative burden of accredited investor verification. 506(c) becomes the better choice when the sponsor’s existing network is insufficient for the raise amount and the sponsor needs to market broadly to reach new accredited investors.
Does 506(c) cost more than 506(b)?
The document drafting cost for 506(b) and 506(c) is substantially the same, since the PPM, Subscription Agreement, and Operating Agreement are structurally similar. The cost difference comes from investor verification. 506(c) requires ongoing verification work — either handled internally by the issuer, by counsel as a separate engagement, or through a third-party verification service at $30 to $75 per investor. For a 20-investor offering, verification adds $600 to $1,500 to the total cost. The PPM legal fees themselves are typically identical.
Can I switch from 506(b) to 506(c) after starting my offering?
Switching from 506(b) to 506(c) mid-offering is extremely difficult and creates significant legal risk. The primary obstacle is that any general solicitation conducted under 506(c) retroactively contaminates the 506(b) period if the SEC determines the offering was integrated. In practice, the safest approach is to terminate the 506(b) offering, wait a reasonable period, and begin a new 506(c) offering. Converting mid-stream is not recommended without experienced securities counsel reviewing the specific facts.
Do both 506(b) and 506(c) require a PPM?
Neither Rule 506(b) nor Rule 506(c) technically requires a Private Placement Memorandum as a matter of law. However, a PPM is the issuer’s primary defense against later claims of inadequate disclosure under the anti-fraud provisions of federal and state securities law. In practice, every competent securities attorney will require a PPM for any Reg D offering regardless of exemption. The PPM documents the disclosures that protect the issuer if an investor later claims they were not adequately informed of the risks.
