506(b) vs 506(c) Syndications: What Changes for the Investor

Two subsections of the same rule, and the difference decides whether a deal may advertise, who may invest in it, and what you will be asked to hand over before your money is accepted.

A 506(b) syndication may not be advertised and may take your word that you are accredited; a 506(c) syndication may be marketed publicly but must verify that every investor is accredited. Both are exemptions under Rule 506 of Regulation D, and nearly every private real estate syndication in the United States is sold under one of them. Which one a sponsor relies on shapes how the deal reached you and what you will be asked for.

The subsections are often written without the parentheses — 506b and 506c — in marketing material and in search. They are the same rules: paragraphs (b) and (c) of 17 CFR 230.506.

What is a 506(b) syndication?¶

A 506(b) syndication is a private offering made without general solicitation. The sponsor can raise an unlimited amount from accredited investors and sell to a limited number of sophisticated non-accredited investors, but it cannot advertise and must know each investor before showing the deal. Accredited status is usually self-certified in a questionnaire.

What is a 506(c) syndication?¶

A 506(c) syndication is a private offering that may be advertised to anyone — websites, webinars, social media, podcasts. In exchange, every purchaser must be accredited, and the issuer must take reasonable steps to verify it, typically by reviewing tax returns or account statements or by obtaining a letter from a CPA, attorney, broker-dealer or registered investment adviser.

The one distinction everything follows from¶

General solicitation — advertising an offering publicly — is prohibited under Rule 506(b) and permitted under Rule 506(c). Everything else is a consequence.

Under 506(b), the sponsor cannot advertise, cannot post the deal on a public website, cannot discuss a live offering on a podcast, and cannot cold-email a purchased list. It must have a substantive pre-existing relationship with each person it shows the offering to. This is why sponsors relying on 506(b) ask you to join an investor list and then wait before sending anything: they are establishing the relationship the exemption requires.

Under 506(c), all of that is allowed. The deal can be marketed openly. The price is that every purchaser must be an accredited investor, and the issuer must take reasonable steps to verify it — not accept a representation, but verify.

What each one asks of you¶

If the deal is 506(b)

If the deal is 506(c)

How it reached you

Through an existing relationship, after a waiting period

It could have been an advertisement, a webinar or a public listing

What you complete

An investor questionnaire, self-certifying your status

A verification process with supporting documents

Documents requested

Usually none

Tax returns, brokerage statements, or a letter from a CPA, attorney, broker-dealer or adviser

Non-accredited investors

Permitted, capped in number, and owed much more disclosure

Not permitted at all

Disclosure you receive

More, if any non-accredited investors are in the deal

Whatever the sponsor chooses to provide

Two consequences worth internalizing.

A publicly advertised deal that does not verify you has a problem. If you found an offering through an advertisement and the subscription process asks only for a checkbox, the issuer is relying on 506(c) without meeting its condition. That is the issuer's exposure rather than yours, but it is a data point about how carefully the offering is being run.

506(c) marketing is not reviewed marketing. Permission to advertise is not permission to say anything. The anti-fraud provisions of the securities laws apply to every webinar, email and landing page, but nobody checks those materials before they reach you. An advertisement for a 506(c) deal is a sales document written by the issuer, and the offering documents govern where the two disagree.

A waiting period is not a sales technique. When a sponsor says you must be on the list for a while before seeing deals, it is complying with 506(b). The requirement is real.

Verification under 506(c), concretely¶

The SEC does not prescribe a single method; it requires reasonable steps proportionate to the circumstances. Four approaches are standard:

Income test. Tax returns or equivalent filings for the two most recent years, plus your written representation that you reasonably expect to reach the threshold in the current year.
Net worth test. Statements of assets, together with a consumer credit report to establish liabilities, dated recently.
Third-party confirmation. Written confirmation from a registered broker-dealer, a registered investment adviser, a licensed attorney or a certified public accountant that they have taken reasonable steps and concluded that you qualify.
Prior verification. For someone verified previously by the same issuer, a written representation that the status continues, within the permitted period.

Most sponsors outsource this to a verification service, which is why the request often arrives from a company name you have not heard of.

The non-accredited question¶

Only 506(b) permits non-accredited purchasers, and it caps them at a limited number per offering. Those purchasers must be sophisticated — possessing knowledge and experience sufficient to evaluate the merits and risks, alone or with a purchaser representative — and they must be given substantially more disclosure than accredited investors receive, approaching what a registered offering would require.

That disclosure burden is precisely why most sponsors decline to include any. It is common for a 506(b) deal to be open to accredited investors only, despite the exemption permitting otherwise.

What happens if the exemption is blown¶

Worth understanding because it is the risk an investor bears from the issuer's carelessness rather than from the property.

If an issuer fails to satisfy the conditions of the exemption it claimed — advertises a 506(b) offering, or accepts an unverified purchaser in a 506(c) one — the offering may lose its exemption. Securities sold without a valid exemption and without registration can give purchasers a right of rescission: the right to unwind the purchase and recover what they paid, generally with interest.

That sounds like an investor protection and it is a poor one in practice. Rescission is a claim against an entity that has already spent the money on a building, it has to be asserted within a limitation period, and asserting it means litigation. The realistic value of the remedy depends entirely on whether there is anything to recover from.

There is also a second-order effect: an issuer facing rescission claims from some investors has a problem that damages every other investor in the same deal, whether or not they were affected by the defect.

The practical takeaway is not that you should evaluate securities law compliance yourself. It is that procedural carelessness in the offering process is a signal about operational carelessness generally, and it is one of the few signals you can observe directly before investing — because you experience the subscription process yourself.

Establish which subsection the deal relies on — it is stated in the memorandum and on the Form D — and let it inform two things.

If it is 506(c), expect to hand over financial documents, and treat a process that skips them as a signal about operational discipline generally. Sponsors who are careless about the condition their own exemption depends on are rarely careless only there.

If it is 506(b), note that you were shown the deal because of a relationship, and read the subscription agreement to see exactly what you are representing about yourself. The representation is what the issuer will rely on; making it inaccurately is your problem, not theirs.

Either way, look the sponsor up on EDGAR before deciding. The Form D filings are public, searchable and free, and they establish what has actually been raised.

Both subsections share one more condition, which is about people rather than process: the exemption is lost if the sponsor or another covered person has a disqualifying event. That rule is covered in Rule 506(d) bad actor disqualification.

Questions readers ask

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

506(b) forbids general solicitation, so the sponsor cannot advertise and needs a pre-existing relationship with you. It generally accepts your written representation of accredited status. 506(c) permits public advertising but requires every purchaser to be accredited and verified with documents.

Can a non-accredited investor participate in a syndication?

Only in a 506(b) offering, and only up to a limited number of purchasers who must be financially sophisticated and who must receive substantially more disclosure. Most sponsors avoid this entirely because of the added disclosure burden.

What documents does 506(c) verification require?

Reasonable steps, which in practice means tax returns or W-2s for the income test, brokerage and account statements plus a credit report for the net worth test, or written confirmation from a registered broker-dealer, registered investment adviser, licensed attorney or certified public accountant.

Does a checkbox satisfy 506(c)?

No. Self-certification alone does not meet the reasonable steps standard. If a publicly advertised deal accepts a checkbox as proof, the issuer has a problem with its exemption, and that is worth knowing before you wire.

Is one exemption safer for the investor?

Neither is safer. Both are private, unregistered and unreviewed. The verification in 506(c) protects the issuer's exemption, not your money.
