Reg D & Compliance
What Is a 506(c)? Requirements, Verification, and Advertising Rights
What is a 506(c)? It's an exemption under Rule 506 of Regulation D — the SEC safe harbor most private offerings use — that lets an issuer advertise a private securities offering publicly, on two conditions: every investor must be accredited, and the issuer must take reasonable steps to verify it. In practice, a "506(c) offering" is a private raise (most often a real estate syndication or fund) that can legally run ads, publish content, and pitch strangers, with no cap on how much it raises.

This page is the plain-English answer for the sponsor hearing the term for the first time: what 506(c) requires, who actually uses it, what it is not, and how it differs from its sibling, 506(b). When you're ready to go deeper, each section routes to the full guide on that piece.
The one-paragraph answer, unpacked
Regulation D is the set of SEC rules that lets companies sell securities without registering the offering — the "private placement" path that funds most syndications. Rule 506 is its workhorse safe harbor, and it splits into two doors. Rule 506(b) is the traditional one: no public advertising, investors from your existing network. Rule 506(c), added under the JOBS Act in 2013, is the modern one: general solicitation — public advertising of the offering — is permitted, in exchange for a stricter investor standard and a verification duty.
So when a sponsor says "we're raising under 506(c)," they're telling you three things at once: the offering is exempt from SEC registration, it can be marketed in public, and every check that clears will come from a verified accredited investor.
506(c) requirements: the table
The requirements are short enough to fit in one table — what's deceptive is how much operational weight sits behind each row:
| Requirement | What it means in practice |
|---|---|
| Accredited investors only | Every purchaser must be accredited — commonly $200k income ($300k jointly) in each of the last two years, or $1M net worth excluding the primary residence, plus certain licensed professionals and entities. No non-accredited seats at all. |
| Reasonable verification of accreditation | Self-certification checkboxes don't count. You verify through income documents, asset statements, a professional letter from the investor's CPA/attorney/broker-dealer/adviser, or a third-party service (commonly ~$50–$100 per investor). |
| Form D filing | File Form D with the SEC within 15 days of the first sale. Most states also require blue-sky notice filings (with fees) where your investors live. |
| Bad-actor disqualification | The exemption isn't available if the issuer or certain covered persons have disqualifying events — counsel runs these checks as standard practice. |
| Anti-fraud compliance | Exempt from registration, never from truth. Every ad, webinar, and deck is subject to anti-fraud rules — misstatements and omissions carry liability. |
| No offering size cap | Rule 506 has no dollar limit and no cap on the number of accredited investors. The practical ceiling is your marketing reach, not the rule. |
If you want each row dissected — the verification safe harbors, the channel-by-channel advertising playbook, what you still can't say in an ad — that's our full 506(c) rule guide. This table is the whole skeleton.
Who uses 506(c), and why
The searcher asking "what is a 506c" has usually just heard the term from a specific kind of sponsor — because 506(c) fits a recognizable set of situations:
- The sponsor whose network is tapped. The first deal closed on friends and family under 506(b); the second strained the same list. Deal three is bigger than the rolodex, and growth has to come from strangers — which only 506(c) allows you to market to.
- The sponsor raising on a deadline. A property under contract with a closing date can't wait for referrals to trickle in. Paid ads, webinars, and public outreach compress the top of the funnel in a way private networking can't.
- The repeat syndicator building a capital pipeline. Audiences compound: the email list, the content library, and the webinar registrants from this raise become the launch pad for the next. That compounding only works when marketing in public is legal.
- The fund or platform raising continuously. Always-on offerings are effectively marketing operations — public content and advertising are structural, not optional, which makes 506(c) the default architecture.
Notice the common thread: every one of these is a sponsor whose constraint is audience, not deal flow. That's the pain 506(c) exists to solve — the raise capped at the size of your personal network while the deal demands more. What 506(c) doesn't solve is the marketing itself: the rule opens the channel, and the sponsor still has to build the audience, the funnel, and the follow-up that turn advertising rights into wired capital.
506(c) at a glance
The compact fact sheet — the things worth remembering after you close this tab:
- Public advertising: allowed. Ads, social content, webinars, podcasts, press — general solicitation is the defining feature.
- Investors: accredited only. No exceptions, no 35-seat allowance for non-accredited investors.
- Verification: required. Reasonable steps — documents, professional letters, or third-party services — not a self-check box.
- Offering size: uncapped. No dollar limit, no investor-count limit for accredited investors.
- Form D: due within 15 days of the first sale, plus state blue-sky notice filings.
- Anti-fraud rules: always apply, to every public word.
- Created: 2013, under the JOBS Act.
What a 506(c) is not
Because the term travels fast in sponsor circles, a few misconceptions travel with it. Clearing them up early saves expensive confusion later:
- It is not a registration. A 506(c) offering is exempt from SEC registration — that's the entire point. Calling it "registered with the SEC" in marketing is wrong and the kind of misstatement anti-fraud rules exist for.
- It is not SEC approval. Filing Form D notifies the SEC of the offering; nobody at the SEC reviews or blesses your deal. Implying approval or endorsement is a classic red flag.
- It is not a license to promise returns. Advertising rights cover the channel, not the claims. Guaranteed-return language and cherry-picked track records create liability whether they appear in a PPM or an Instagram caption.
- It is not investor-side paperwork. The 506(c) election, the verification duty, and the filings all belong to the issuer. If you're the sponsor, this is your compliance workload — not your investors'.
- It is not automatic. The conditions are real: close one unverified investor and the exemption itself is undermined. Sponsors run 506(c) raises with securities counsel for a reason.
506(c) vs 506(b) in one glance
The other door in Rule 506 is 506(b) — and the choice between them is the first real decision of any Reg D raise. The one-glance version:
| 506(c) | 506(b) | |
|---|---|---|
| Public advertising | Allowed | Prohibited |
| Investors | Accredited only, verified | Self-certified accredited + up to 35 sophisticated non-accredited |
| Practical raise ceiling | Your marketing reach | Your existing network |
The rough heuristic: if your existing network can comfortably fund the deal — or you must include non-accredited friends and family — 506(b) keeps things frictionless. If growth depends on reaching investors you haven't met, 506(c) is the exemption built for it. The full trade-off analysis, including why you shouldn't casually flip from one to the other mid-raise, lives in our 506(c) vs 506(b) comparison. And whichever door you choose, the structural decision deserves a conversation with securities counsel before anything about the offering goes public.
Frequently asked questions
What is a 506(c) in simple terms?
A Regulation D exemption that lets a company advertise a private securities offering publicly — ads, social media, webinars — as long as every investor is accredited and the issuer takes reasonable steps to verify it. There's no cap on the amount raised.
What are the 506(c) requirements?
Accredited investors only, reasonable verification of each investor's status (documents, professional letters, or a third-party service), Form D filed within 15 days of the first sale, state blue-sky notice filings, no disqualified bad actors, and full anti-fraud compliance in every communication.
Is a 506(c) offering registered with the SEC?
No — it's exempt from registration. Form D is a notice filing, not a review or approval. The SEC neither examines nor endorses 506(c) offerings, and marketing that implies otherwise is a compliance problem.
Who can invest in a 506(c)?
Accredited investors only — commonly individuals with $200k income ($300k jointly) in each of the last two years, or $1M net worth excluding their primary residence, plus certain license holders and qualifying entities. Each one must be verified, not just self-certified.
How much can you raise under 506(c)?
There's no limit. Rule 506 offerings carry no dollar cap and no ceiling on the number of accredited investors — the same exemption covers a $2M syndication and a nine-figure fund. The practical limit is marketing reach.
What's the difference between 506(b) and 506(c)?
506(b) prohibits public advertising but allows self-certified accredited investors plus up to 35 sophisticated non-accredited investors. 506(c) permits public advertising but restricts the offering to verified accredited investors only. The choice usually comes down to whether your network can fund the raise.
