Regulation D
Regulation D is a set of SEC rules that provides exemptions from federal securities registration requirements, allowing companies to raise capital through private placements. Instead of filing a full registration statement and prospectus, issuers can sell securities to accredited investors and, in some cases, a limited number of sophisticated non-accredited investors.
How Regulation D Works
The Securities Act of 1933 requires any offer or sale of securities to be registered with the SEC — unless an exemption applies. Regulation D provides the most commonly used exemptions. Companies file a brief Form D notice with the SEC (usually within 15 days of the first sale) instead of a full registration package.
Reg D does not exempt issuers from anti-fraud provisions. Companies must still provide accurate, non-misleading information to investors. The exemption only removes the registration and prospectus requirements.
The Three Main Reg D Exemptions
| Rule | Max Raise | Investor Restrictions | General Solicitation | SEC Filing |
|---|---|---|---|---|
| Rule 504 | $10 million (12 months) | No accreditation required (state law applies) | Allowed in some states | Form D |
| Rule 506(b) | Unlimited | Unlimited accredited + up to 35 sophisticated non-accredited | Not allowed | Form D |
| Rule 506(c) | Unlimited | Accredited investors only | Allowed | Form D |
Rule 504: Small Offerings
Rule 504 allows companies to raise up to $10 million in a 12-month period. There are no specific federal restrictions on investor qualifications, but state securities laws (blue sky laws) still apply. This exemption is typically used by smaller companies in early-stage fundraising.
Securities issued under Rule 504 may be restricted (meaning buyers cannot freely resell them) depending on state registration requirements. If the offering is registered in at least one state that requires public filing and delivery of a disclosure document, the securities may be freely tradable.
Rule 506(b): The Workhorse Exemption
Rule 506(b) is the most widely used Reg D exemption. There is no cap on the amount raised. Issuers can sell to an unlimited number of accredited investors plus up to 35 non-accredited investors who are “sophisticated” — meaning they have sufficient knowledge and experience in financial matters to evaluate the investment.
The catch: no general solicitation or advertising is allowed. Companies must have a pre-existing relationship with investors before offering securities. If non-accredited investors participate, the issuer must provide disclosure similar to what would be required in a registered offering (audited financial statements, risk factors, etc.).
506(b) offerings benefit from federal preemption — they override state blue sky laws, so companies do not need to register the offering in each state where they sell securities.
Rule 506(c): General Solicitation Allowed
Added by the JOBS Act in 2013, Rule 506(c) permits general solicitation and advertising — companies can publicly announce their offering through websites, social media, conferences, and other channels. The trade-off: all buyers must be accredited investors, and the issuer must take reasonable steps to verify accredited status.
Verification methods include reviewing tax returns, bank statements, brokerage accounts, or obtaining written confirmation from a CPA, attorney, or registered investment advisor. Self-certification alone is not sufficient under 506(c).
Rule 506(b) vs. Rule 506(c)
| Feature | Rule 506(b) | Rule 506(c) |
|---|---|---|
| Capital Limit | None | None |
| General Solicitation | Prohibited | Permitted |
| Investor Types | Accredited + up to 35 non-accredited | Accredited only |
| Verification | Self-certification accepted | Reasonable verification required |
| Disclosure to Non-Accredited | Full disclosure required | N/A — no non-accredited investors |
| State Preemption | Yes | Yes |
| Typical Use | PE funds, VC funds, real estate syndications | Online platforms, crowdfunding portals, publicly marketed deals |
Form D Filing Requirements
Companies using Reg D must file Form D with the SEC, typically within 15 days of the first sale of securities. Form D is a brief notice — not a registration statement — that includes basic information: the company name, its officers, the type of securities offered, the exemption claimed, and the amount being raised.
Form D filings are publicly available on the SEC’s EDGAR database. Analysts and investors can search these filings to track private fundraising activity, identify emerging companies, and monitor capital flows into private equity and venture capital.
Form D filings on EDGAR are a goldmine for tracking private market activity. You can see how much a company is raising, who the executive officers are, and whether they are using 506(b) or 506(c). Many startups file their first Form D well before any IPO discussions — watching these filings can give you an early signal on companies to watch.
Restrictions on Resale
Securities sold under Regulation D are typically “restricted securities” under Rule 144. Buyers generally cannot resell them on the open market without either registering the securities or meeting the conditions of a resale exemption. For most non-affiliated holders, this means a six-month to one-year holding period before resale is permitted.
Institutional buyers may resell to qualified institutional buyers (QIBs) under Rule 144A, which provides liquidity for institutional-sized positions without a holding period.

Frequently Asked Questions
What is a Regulation D offering?
A Regulation D offering is a private securities sale that is exempt from full SEC registration. Companies file a brief Form D notice and sell securities to qualified investors — primarily accredited investors — without the cost and time required for a public offering. It is the most common method for private equity funds, venture capital firms, and private companies to raise capital.
What is the difference between Rule 506(b) and 506(c)?
Rule 506(b) prohibits general solicitation but allows up to 35 sophisticated non-accredited investors alongside unlimited accredited investors. Rule 506(c) permits general solicitation and advertising but restricts participation to accredited investors only and requires the issuer to verify their status. Most traditional fund raises use 506(b); online platforms and publicly marketed offerings use 506(c).
Do Regulation D offerings need to be registered with state regulators?
Rule 506 offerings are federally preempted — they override state registration requirements under the National Securities Markets Improvement Act. However, states can still require Form D notice filings and collect fees. Rule 504 offerings do not have federal preemption and must comply with applicable state blue sky laws.
Can you lose money in a Regulation D investment?
Yes. Reg D investments carry significant risks including illiquidity (you cannot easily sell restricted securities), lack of public disclosure, higher default rates for early-stage companies, and potential total loss of capital. The SEC exemption removes registration requirements — it does not reduce investment risk.
How long must you hold Regulation D securities before selling?
Under Rule 144, non-affiliated holders of restricted securities from an SEC-reporting company must wait six months before reselling. For non-reporting companies, the holding period is one year. Institutional holders may resell earlier to QIBs under Rule 144A without holding period requirements.
