506c vs 506b: Rule 506 of Regulation D

506c vs 506b is the choice between two exemptions under Rule 506 of Regulation D. Rule 506(c) lets you generally solicit, but every purchaser must be an accredited investor and you must take reasonable steps to verify that status. Rule 506(b) bars general solicitation and advertising, and can include up to 35 non-accredited sophisticated purchasers.

This page is the exemption comparison. The Form D notice is a separate filing — see Form D, blue sky, and SPV compliance. This is general information, not legal, tax, or investment advice. Confirm the current SEC text with counsel before you rely on either exemption.

What Rule 506 of Regulation D covers

Regulation D Rule 506 is a federal path to sell securities without registering the offering with the SEC. Rule 506 of Regulation D splits into two exemptions: Rule 506(b) and Rule 506(c). Both can support an unlimited offering amount if you stay inside the conditions of the rule you actually use.

Shared baseline, under current SEC summaries of each rule:

• Purchasers receive restricted securities.

• A Form D notice is typically due within 15 days after the first sale.

• NSMIA preempts state registration and qualification for these offerings; states may still require notice filings and collect fees.

• Bad-actor disqualification applies.

• Anti-fraud rules still apply. An exemption is not a license to omit material facts.

The split is execution, not the size of the round. 506c vs 506b is how you find buyers, who may buy, and what file you keep on each purchaser.

Rule 506(c): general solicitation with verification

Rule 506(c) is the 506c exemption. The SEC's current summary: you may broadly solicit and generally advertise if (1) every purchaser is an accredited investor, (2) you take reasonable steps to verify that status, and (3) the other Regulation D conditions are met (General solicitation — Rule 506(c), page dated June 21, 2024, last reviewed March 17, 2026).

That is the operating trade. You can put the deal on a public page, run an open webinar, or advertise. You cannot take a non-accredited purchaser. You cannot treat a checkbox as verification.

The SEC describes 506(c) verification as a principles-based, facts-and-circumstances test. Factors typically include the type of accredited investor claimed, the information you already have, how the person was solicited, and terms such as a minimum investment. The rule also lists non-exclusive methods that issuers may use for natural persons, including:

• Income: review IRS forms that report income (for example W-2, 1099, K-1, Form 1040).

• Net worth: review specified asset documents dated within the prior three months, plus a consumer report, plus a written representation.

• Third-party letter: written confirmation from a registered broker-dealer, an SEC-registered investment adviser, a licensed attorney, or a CPA that they took reasonable steps within the prior three months and determined the purchaser is accredited.

• Prior verification: in limited cases, a later written representation, if you previously verified that person, you are not aware of contrary information, and you are still within five years of that verification.

You are not required to use that list. Different purchasers in the same offering can be verified different ways. What you cannot do is skip the steps. The SEC staff's current note is blunt: self-certification by checking a box, without other knowledge of the investor's financial circumstances or sophistication, is not enough for 506(c) verification — and it is not enough for 506(b) reasonable belief either (Assessing Accredited Investors under Regulation D, dated March 21, 2025, last reviewed April 24, 2026).

Who counts as accredited is Rule 501(a), not a marketing label. Under current SEC summaries, natural persons may qualify on net worth over $1 million excluding primary residence (alone or with a spouse or partner); income over $200,000, or $300,000 with a spouse or partner, in each of the prior two years with a reasonable expectation of the same this year; certain professional licenses in good standing (Series 7, 65, or 82); and other 501(a) categories. Entities have separate tests. Those thresholds move only when the Commission changes them — treat the live SEC summary as the source, not a blog.

Rule 506(b): no general solicitation

Rule 506(b) is the older private-placement safe harbor under Section 4(a)(2). The SEC's current summary of Rule 506 b:

• No general solicitation or advertising to market the securities.

• Unlimited accredited purchasers.

• No more than 35 non-accredited purchasers. Each of those purchasers, alone or with a purchaser representative, must be sophisticated — capable of evaluating the merits and risks.

• If non-accredited investors participate, they must receive disclosure that generally contains the same type of information as a Regulation A offering, plus financial-statement information specified in Rule 506, and the issuer should be available to answer their questions.

• Unlimited offering amount, restricted securities, Form D, state-notice reservation, and bad-actor rules, as above.

The 506(b) accredited standard is reasonable belief, not the 506(c) verification methods. A questionnaire plus a real relationship and whatever else supports that belief is how most GPs run a 506(b) book. A naked checkbox is still a weak file.

In practice, staying inside 506(b) means keeping the offer off public channels. A passworded data room sent to named people is a different fact pattern from an unrestricted landing page. Where the line sits is a legal call on your facts, not a slogan.

If you actually take non-accredited purchasers, budget the disclosure work. Many SPV sponsors cap the vehicle at accredited-only even under 506(b), so they never trigger that package. That is an operational choice, not a requirement of Rule 506(b).

506c vs 506b, side by side

Use the table as a map, not as a closing checklist. The rule text and your offering documents control.

How GPs actually pick

The useful question is not "which exemption is better." It is which constraint you can live with for this vehicle.

Use 506(c) when the raise needs public reach: a public deal page, social posts that are offers, open webinars, or ads. Then build a verification file per purchaser and keep it. Entity subscribers (IRA LLCs, family LLCs, trusts) are where 506(c) books stall — you verify the purchaser named on the subscription, not a nickname on a wire.

Use Rule 506(b) when you can fill the round from people you already know and you want to avoid verification logistics. Keep the marketing private. If you might take sophisticated non-accredited purchasers, staff the disclosure. If you will not, say so in the docs and do not take the check.

Do not mix the two inside one offering. Public marketing plus a 506(b) legend on the PPM is how offerings get re-characterized. A later vehicle can use a different exemption; that is a new offering analysis for counsel, not a form swap in the CRM.

Form D still files either way. The exemption you check on Form D should match how you actually offered and sold. That filing is covered on the Form D page, not here.

What this means for an SPV

Most venture and deal-by-deal vehicles are special purpose vehicles-meaning-in-finance-banking-and-real-world-examples) offering LLC interests under Rule 506. The SPV is the issuer. 506c vs 506b is the exemption the SPV uses, not a product SKU.

Operational consequences we see on live books:

• A 506(c) SPV needs a verification method per purchaser before you accept the subscription, plus a place to store tax forms or third-party letters.

• A 506(b) SPV needs a clean offer trail. Forwarding a public tweet into a "private" round does not make the tweet private.

• Either path still needs Form D and, typically, blue-sky notices in states where you sell.

• Platform onboarding is not a substitute for the exemption. KYC/AML is adjacent work, not 506(c) verification.

Allocations publishes Standard SPV pricing at $9,950 one-time and fund pricing at $19,500/year, with 0% platform carry. See the fee schedule and what it typically costs to create an SPV in 2026. Those figures are formation and administration, not SEC filing fees (the SEC charges none for Form D) and not state notice fees, which vary by state.

If you are choosing infrastructure rather than an exemption, compare SPV platforms on who actually files, who stores the verification file, and who publishes prices.

FAQ

Can I advertise a Rule 506(b) offering on a public website or LinkedIn?

Under current SEC rules, Rule 506(b) does not allow general solicitation or advertising. A public deal page, open webinar, or paid ad is typically 506(c) territory. This is general information, not legal advice.

Does 506(c) require every purchaser to be accredited?

Yes. Rule 506(c) requires that all purchasers are accredited investors and that the issuer takes reasonable steps to verify that status. Non-accredited purchasers are not permitted.

Is a subscription-agreement checkbox enough for 506(c) verification?

No. The SEC staff has said a checkbox alone, without other knowledge of the investor, does not meet 506(c) verification or 506(b) reasonable belief.

Do I still file Form D if I use Rule 506?

Typically yes. A Form D notice is generally due within 15 days after the first sale. Filing is a Rule 503 requirement; it is not, by itself, a condition of the 506 exemption. Walk through the notice, EDGAR, amendments, and blue-sky pieces on Form D & blue-sky SPV compliance.

Rule 506 of Regulation D is the exemption. Form D is the notice. Pick 506c vs 506b from how you will offer and who you will take, then file the notice to match that choice.
