Understanding the differences between Regulation A, Regulation D, and Regulation CF is crucial for both companies seeking to raise capital and investors looking to participate in private markets. Each exemption serves different purposes, has distinct requirements, and offers unique advantages depending on the company's needs and investor base.
All three leave a public filing trail, and that trail is the quickest way to tell them apart in practice: a Reg D raise is reported on a short Form D, a Reg A offering on a full offering circular (Form 1-A), and a Reg CF raise on Form C, posted by the funding portal running the deal.
Overview Comparison
| Feature | Regulation A+ | Regulation D | Regulation CF |
|---|
| Maximum Offering | $20M (Tier 1) / $75M (Tier 2) per 12 months | Unlimited (506); $10M (504) | $5M per 12 months |
| Investor Types | General public | Accredited; 506(b) also allows up to 35 sophisticated non-accredited | General public |
| General Solicitation | Permitted | 506(c) only | Permitted |
| SEC Review | Yes (must be qualified) | No | No |
| Ongoing Reporting | Tier 2: Form 1-K, 1-SA, 1-U | None (annual Form D amendment while selling) | Annual Form C-AR |
Regulation A+ Deep Dive
Regulation A is often called a mini-IPO: the issuer files an offering circular that the SEC reviews and qualifies, then sells to the public. The list of Reg A issuers spans real estate funds, consumer brands and fractional-asset series.
Best For
- Companies seeking substantial funding ($20M - $75M)
- Businesses wanting to access retail investors
- Companies comfortable with public disclosure
- Potential IPO candidates
Advantages
- Broad Investor Base: Can sell to any investor, including non-accredited
- Public Marketing: Full advertising and solicitation permitted
- Testing the Waters: Can gauge interest before filing
- Not Restricted: Securities sold under either tier are not restricted securities, though a trading market may never develop
Disadvantages
- SEC Review Process: The offering must be qualified by the SEC, which commonly takes several months of comment letters
- Extensive Disclosure: Near-IPO level disclosure requirements
- Ongoing Obligations: Continuous reporting requirements
- State Registration (Tier 1): Tier 1 offerings must also be registered in each state where they are sold; Tier 2 preempts state review but caps non-accredited investors at 10% of income or net worth unless the securities are listed
Regulation D Analysis
Regulation D carries most private capital raised in the U.S. The issuer files a Form D within 15 days of the first sale, listing the exemption claimed, the total offering amount, the amount sold so far, the minimum investment, the number of investors, any sales commissions, and the executive officers, directors and promoters involved.

Each exemption serves different purposes in the capital formation ecosystem, and understanding their distinctions is crucial for both issuers and investors.
Companies should work with experienced securities counsel to evaluate which exemption best fits their needs, considering both immediate fundraising goals and long-term strategic objectives. The regulatory landscape continues to evolve, and the 2020 amendments made these exemptions easier to use and combine.
