Reg-CF, Reg-D 506(b), Reg-D 506(c), Reg-A+ vs Reg-S Equity Crowdfunding

Equity crowdfunding has become a popular way for entrepreneurs and small business owners to raise capital for their ventures. In recent years, the Securities and Exchange Commission (SEC) has introduced several regulations that govern equity crowdfunding in the United States. These regulations include Regulation Crowdfunding (Reg CF), Regulation D (Reg D), Regulation A+ (Reg A+), and Regulation S (Reg S).

In this comprehensive guide, we compare these regulations — including the critical differences between Reg D 506(b) and Reg D 506(c) — to help you understand which one might be the best fit for your company. Whether you are a startup looking to raise your first round or a growth-stage company planning a larger offering, choosing the right regulatory framework is one of the most important decisions you will make. For a deeper look at the future of equity crowdfunding, see our companion guide.

Regulation Crowdfunding (Reg CF)

Reg CF was introduced in 2015 as part of the JOBS Act. It allows companies to raise up to $5 million in a 12-month period through a registered funding portal or broker-dealer. Here are some key features of Regulation Crowdfunding.

Advantages of Regulation Crowdfunding (Reg CF)

• Access to a larger pool of investors: With Reg CF, companies can solicit investments from anyone, regardless of their income or net worth.
• Lower costs: Compared to other regulations, Reg CF is less expensive because the legal and compliance costs are lower.
• No SEC registration: Companies don’t need to register with the SEC to raise funds under Reg CF.
• Easier disclosure requirements: The disclosure requirements for Reg CF are less stringent than other regulations, which makes it easier for companies to comply.

Disadvantages of Reg CF

• Low investment limits: Investors can only invest up to a certain amount depending on their net worth and income.
• Limitations on the amount of capital raised: Companies can only raise up to $5 million in a 12-month period.
• No secondary market: Investors are not able to sell their shares until a liquidity event occurs.

Key Features and Requirements of Reg CF

• Investment limits: Investors can invest up to $2,200 or 5% of their annual income or net worth (whichever is greater) in a 12-month period.
• Financial disclosure requirements: Companies are required to provide financial statements certified by an independent public accountant for offerings over $107,000.
• Use of funds: Companies must disclose how the funds will be used and provide updates on the progress of the project.
• Reporting requirements: Companies must file annual reports with the SEC and provide updates to investors.

Examples of Successful Reg CF Campaigns

Some successful companies that have raised funds through Reg CF include BrewDog, a craft beer company, and Indiegogo, a crowdfunding platform. Reg CF has been particularly popular among startups in food and beverage, e-commerce, and consumer goods sectors.

Regulation S (Reg S) Equity Crowdfunding

Reg S equity crowdfunding allows companies to offer and sell securities outside of the United States without registration under the Securities Act. Here are some key features of Reg S equity crowdfunding:

Key Characteristics of Reg S Equity Crowdfunding

• No access to U.S. investors: Reg S equity crowdfunding allows companies to sell securities to investors outside of the United States. While this can be an advantage for companies looking to raise capital globally, it also means that they cannot sell securities to U.S. investors. This limits the potential pool of investors and may make it more difficult for companies to raise capital.
• Compliance with foreign securities laws: In addition to complying with U.S. securities laws, companies that use Reg S equity crowdfunding must also comply with the securities laws of the countries where they sell securities. This can be a complex and time-consuming process, as different countries have different securities laws and regulations. Companies may need to hire legal and financial advisors in each country to ensure that they are complying with the relevant laws and regulations.
• Limited visibility and credibility: Reg S equity crowdfunding may not provide the same level of visibility and credibility as other equity crowdfunding regulations, such as Reg A+ and Reg D. This is because Reg S offerings are not subject to the same level of disclosure requirements as other regulations, and there may be less information available to investors about the company and its operations.
• Potentially limited capital raising: While there is no limit on the amount of capital that can be raised under Reg S, the pool of potential investors is smaller than under other regulations, such as Reg A+ and Reg D. This may make it more difficult for companies to raise large amounts of capital.
• Limited marketability: Securities sold under Reg S may not be as marketable as securities sold under other regulations, such as Reg A+ and Reg D. This is because the securities cannot be sold to U.S. investors, which may limit the secondary market for the securities.

Reg S is particularly relevant for companies pursuing token sales and blockchain-based fundraising, as many token offerings target international investors. Companies looking at global capital raising may also consider combining Reg S with Reg D 506(c) for U.S. accredited investors.

Comparison of the Five Regulations

Regulation Crowdfunding (Reg CF), Regulation D 506(b), Regulation D 506(c), Regulation A+ (Reg A+), and Regulation S (Reg S) are the five regulations that govern equity crowdfunding in the United States.

Key Differences Between These Regulations

• Investor type: Reg CF allows companies to sell securities to both accredited and non-accredited investors, while Reg D 506(b) and Reg D 506(c) allow companies to sell securities to accredited investors only. Reg A+ allows companies to sell securities to both accredited and non-accredited investors, but the offering is subject to additional requirements, such as filing a Form 1-A with the SEC. Reg S equity crowdfunding allows companies to sell securities to investors outside of the United States.
• Capital raising limit: Reg CF allows companies to raise up to $5 million, while Reg D 506(b) and Reg D 506(c) have no limit on the amount of capital that can be raised. Reg A+ allows companies to raise up to $75 million, but the offering is subject to additional requirements, such as filing a Form 1-A with the SEC. Reg S has no limit on the amount of capital that can be raised.
• Advertising restrictions: Reg D 506(b) prohibits general solicitation, while Reg D 506(c) allows for general solicitation. Reg CF and Reg A+ allow for general solicitation, but the offering is subject to additional requirements. Reg S allows for general solicitation.
• Verification of investor status: Reg CF and Reg D 506(b) do not require companies to verify the accredited status of the investors, while Reg D 506(c) requires companies to take reasonable steps to verify the accredited status of the investors.
• Compliance costs: The legal and compliance costs for Reg CF are generally lower compared to Reg D 506(b), Reg D 506(c), and Reg A+ due to the lower capital raising limit and less stringent requirements. Reg S has its own set of requirements and compliance costs.

Which Regulation Is Best for Different Types of Companies?

The answer to this question depends on several factors, including the size of the company, the amount of capital needed, the type of investors targeted, and the desired level of regulatory compliance. Here are some guidelines to help companies and investors choose the right regulation:

• Reg CF may be a good option for companies that want to raise up to $5 million from both accredited and non-accredited investors, without the need for extensive legal and compliance work.
• Reg D 506(b) may be a good option for companies that want to raise capital from accredited investors through pre-existing relationships or personal networks without general solicitation.
• Reg D 506(c) may be a good option for companies that want to raise capital from accredited investors through general solicitation, but are willing to take on the additional compliance costs associated with verifying the accredited status of the investors.
• Reg A+ may be a good option for companies that want to raise up to $75 million from both accredited and non-accredited investors, and are willing to undergo the additional compliance work associated with filing a Form 1-A with the SEC.
• Reg S may be a good option for companies that want to raise capital from investors outside of the United States.

Conclusion: Choosing the Right Equity Crowdfunding Regulation

Each of the five equity crowdfunding regulations — Reg CF, Reg D 506(b), Reg D 506(c), Reg A+, and Reg S — serves a different purpose and caters to different company profiles, capital needs, and investor targets. The right choice depends on how much capital you need, whether you want to reach accredited or non-accredited investors (or both), your budget for compliance and legal costs, and whether you are targeting U.S. or international investors.

Frequently Asked Questions

What is the difference between Reg CF, Reg D, Reg A+, and Reg S?

These are four SEC regulations governing equity crowdfunding. Reg CF allows companies to raise up to $5M from anyone (accredited and non-accredited investors). Reg D 506(b) allows unlimited raises from accredited investors without public advertising. Reg D 506(c) allows unlimited raises from accredited investors with public advertising but requires investor verification. Reg A+ allows raises up to $75M from both accredited and non-accredited investors. Reg S allows companies to raise capital from investors outside the United States.

Which equity crowdfunding regulation is best for startups?

For most early-stage startups, Reg CF is the best starting point because it has the lowest compliance costs, allows investments from anyone regardless of income or net worth, and is accessible through platforms like Wefunder, Republic, and StartEngine. For startups with access to accredited investor networks, Reg D 506(b) or 506(c) may also be strong options.

What is the maximum amount I can raise under each regulation?

Reg CF: up to $5 million in 12 months. Reg D 506(b): no limit. Reg D 506(c): no limit. Reg A+ Tier 1: up to $20 million in 12 months. Reg A+ Tier 2: up to $75 million in 12 months. Reg S: no limit. For raises over $5M, companies typically move to Reg D 506(c) for accredited investors or Reg A+ for both accredited and non-accredited investors.

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

The key differences are advertising and verification. Reg D 506(b) prohibits general solicitation (public advertising) but does not require formal verification of investor accreditation. Reg D 506(c) allows general solicitation through websites, social media, and performance marketing, but requires companies to take reasonable steps to verify each investor’s accredited status. Both allow unlimited capital raising from accredited investors.

What is an accredited investor?

An accredited investor is an individual with a net worth of at least $1 million (excluding primary residence) or an annual income of at least $200,000 (or $300,000 for married couples) for the past two years, with a reasonable expectation of reaching the same income level in the current year. Certain entities such as banks, insurance companies, and trusts with assets exceeding $5 million also qualify. Reg D 506(b) and 506(c) are limited to accredited investors, while Reg CF and Reg A+ are open to both accredited and non-accredited investors.

Can I use multiple regulations at the same time?

Yes. Many companies use a stacked regulatory strategy — for example, combining Reg CF (for retail investors) with Reg D 506(c) (for accredited investors) and Reg S (for international investors). This approach maximizes your total addressable investor pool but requires careful legal planning to ensure compliance across all regulations. Consult with our team to discuss multi-regulation strategies.

What are the compliance costs for each regulation?

Reg CF has the lowest compliance costs, making it ideal for early-stage companies. Reg D 506(b) has moderate costs, primarily legal fees for preparing offering documents and Form D filing. Reg D 506(c) has higher costs due to the investor verification requirement. Reg A+ has the highest compliance costs among U.S. regulations, as it requires filing a Form 1-A offering statement with audited financial statements. Reg S compliance costs vary by country and can be complex.

What platforms can I use for equity crowdfunding?

For Reg CF, popular platforms include Wefunder, Republic, StartEngine, Dalmore Group, and DealMaker. For Reg D offerings, companies often work directly with broker-dealers or use platforms that specialize in accredited investor offerings. For Reg A+, companies can use platforms like StartEngine for Tier 2 offerings or work with specialized investment banks. See our detailed platform comparison guide for more information.

How long does it take to launch an equity crowdfunding campaign?

Timelines vary by regulation. Reg CF campaigns can be launched in 4–8 weeks with proper preparation. Reg D 506(b) and 506(c) offerings can be launched relatively quickly once documentation is prepared. Reg A+ campaigns take longer — typically 3–6 months — due to the SEC qualification process for the Form 1-A offering statement. The marketing and investor acquisition strategy should be planned well in advance of the launch date.

Why is marketing important for equity crowdfunding success?

Filing the regulatory paperwork is necessary but not sufficient for a successful raise. Effective performance marketing, targeted investor acquisition, strong branding, and conversion optimization are what determine whether a campaign hits its fundraising goals. Companies that invest in professional crowdfunding marketing consistently outperform those that rely solely on platform traffic. At Growth Turbine, we have supported 200+ campaigns with an 87% success rate because we combine regulatory expertise with data-driven marketing execution.
