Reg CF vs Reg A+ vs Reg D: The Complete Guide for Founders (2026)

Every limit, every requirement, every cost, and every outcome. With real examples for each exemption. The only guide you need before choosing how to raise.

When a founder decides to raise capital, the first question is not how much to raise or who to approach. The first question is which legal exemption to raise under. Get it wrong and you spend months on the wrong compliance path, pay legal fees you didn't need to, or discover mid-raise that your investor pool is smaller than you thought.

This guide covers every material difference between Regulation Crowdfunding (Reg CF), Regulation A+ (Reg A+), and Regulation D (Reg D) — the three exemptions that cover the vast majority of startup and growth-stage capital raises in the United States. We explain what each one is, who it is for, what it costs, how long it takes, what happens after you close, and what a realistic outcome looks like for each path.

No legal jargon without explanation. No vague summaries. Just the information you need to make the decision.

📊 Side-by-Side: Reg CF vs Reg A+ vs Reg D at a Glance

EXEMPTION #1

🌱 What Is Regulation Crowdfunding (Reg CF)?

Regulation Crowdfunding, or Reg CF, was created by the JOBS Act of 2012 and went live in 2016. It allows US-incorporated companies to raise up to $5 million per 12-month period from both accredited and non-accredited (retail) investors, using an online platform registered with FINRA as a funding portal or broker-dealer.

Reg CF is the only federal exemption designed specifically to allow everyday retail investors — people who are not wealthy enough to qualify as accredited — to invest in private startup companies. This is what makes it different from every other exemption.

What are the Reg CF investor limits?

Non-accredited investors can invest, but their annual investment across all Reg CF campaigns is capped based on their income or net worth:

Accredited investors (those with $200K+ individual income or $1M+ net worth) face no cap under Reg CF. In practice, most Reg CF campaigns raise a mix of smaller retail checks ($500–$5,000) and larger accredited checks ($10,000–$100,000+).

What does a Reg CF raise require?

Filing: Companies file a Form C with the SEC before launching. This includes two years of financial statements (reviewed by an accountant for raises up to $1.235M, audited for raises above that), a description of the business, use of proceeds, cap table, and risk factors. Form C is publicly available on the SEC's EDGAR database.

Platform requirement: All Reg CF transactions must happen through a single FINRA-registered funding portal or broker-dealer. You cannot accept Reg CF investments directly on your own website or via email.

Escrow: Funds are held in escrow until the raise hits its minimum target. If the minimum is not reached by the campaign deadline, all investors are refunded automatically.

Ongoing reporting: After closing, companies must file an annual report (Form C-AR) with the SEC until the company has fewer than 300 shareholders of record, has filed at least one annual report and had total assets under $10M for three consecutive years, or has gone public or been acquired.

What does Reg CF cost?

Legal fees to prepare a Form C typically run $5,000–$25,000 depending on complexity and whether the company needs audited financials. Platform fees vary but typically include a percentage of capital raised (4–8%) plus a payment processing fee (0.5–1%). Some platforms also charge upfront setup fees of $5,000–$15,000.

Real Reg CF Example

Company: A consumer beverage brand with $400K in revenue, 2,000 email subscribers, and a community following on Instagram.

Target: $500,000 minimum, $1.5M maximum.

What happened: The company launched on a FINRA-registered portal with a 45-day campaign. They hit their $500K minimum in 18 days driven by their email list and social audience. They extended the campaign and closed at $1.1M from 430 investors. Legal cost was $12,000. Platform fees totaled $66,000 (6%). Net proceeds: $1.022M. Timeline from decision to close: 11 weeks.

Outcome: 430 investors became brand ambassadors. The company used the capital for national retail distribution. The investor community generated organic word-of-mouth that reduced paid marketing costs by an estimated 30% in the following year.

EXEMPTION #2

🚀 What Is Regulation A+ (Reg A+)?

Regulation A+ was created by the JOBS Act and updated in 2015. It allows companies to raise up to $75 million per 12-month period (under Tier 2) from both accredited and retail investors, with SEC qualification (a lighter version of a full public offering review). Reg A+ is sometimes called a "mini-IPO" because its disclosure requirements and investor base more closely resemble a public offering than a private placement.

There are two tiers. Tier 1 allows raises up to $20M but requires state-by-state registration (the "blue sky" laws), which makes it impractical for most companies. Almost all Reg A+ raises use Tier 2, which preempts state securities laws and allows public advertising nationally.

What are the Reg A+ investor limits?

Accredited investors have no cap. Non-accredited investors are limited to investing no more than 10% of the greater of their annual income or net worth per Reg A+ offering (not across all offerings — per offering). This is more permissive than Reg CF for retail investors who want to write larger checks.

What does a Reg A+ raise require?

SEC qualification: Unlike Reg CF (which is filed but not reviewed), Reg A+ requires the SEC to formally qualify your offering circular before you can accept money. This is a full review process. The SEC will comment on your disclosure document (Form 1-A) and you must respond to their comments, sometimes in multiple rounds. This is the biggest difference between Reg A+ and the other exemptions — it takes time and the SEC has real input into your disclosure language.

Offering circular: Form 1-A includes two years of audited financial statements, a detailed business description, management backgrounds, use of proceeds, risk factors, and a description of the securities being offered. This is a substantive document, typically 50–150 pages, prepared with securities counsel.

No platform requirement: Unlike Reg CF, Reg A+ raises do not require a FINRA-registered portal. Companies can sell directly on their own website, through a broker-dealer, or both simultaneously. This gives issuers more flexibility in how they structure their investor acquisition funnel.

Ongoing reporting: Tier 2 issuers must file annual reports (Form 1-K), semi-annual reports (Form 1-SA), and current reports for material events (Form 1-U). This reporting obligation continues until the company goes public, gets acquired, or has fewer than 300 shareholders and less than $10M in assets.

What does Reg A+ cost?

Legal fees for a Reg A+ offering typically run $50,000–$150,000 and can go higher for complex structures or contentious SEC review. Audited financials add $15,000–$50,000 depending on company size. Platform or broker-dealer fees (if used) typically run 5–8% of capital raised. Total all-in cost for a $5M Reg A+ raise is often $150,000–$400,000 — which is why Reg A+ generally only makes sense if you are raising $3M or more.

Real Reg A+ Example

Company: A PropTech platform with $2M in revenue, 12,000 users, and a plan to raise $8M to expand into three new markets.

What happened: The company filed Form 1-A, went through two rounds of SEC comments (total review time: 4.5 months), and launched a public offering on their own website plus one broker-dealer platform. They raised $8M over 90 days from 1,800 investors. Legal and accounting costs totaled $185,000. Platform fees totaled $480,000 (6%). Net proceeds: approximately $7.335M.

Outcome: The company used the raise to expand into two of three target markets. The Reg A+ offering also served as a brand-building exercise — investors became users, and the public nature of the offering generated press coverage that a private raise would not have. The company is now preparing a Series A with institutional investors.

EXEMPTION #3

🏦 What Is Regulation D (Reg D)?

Regulation D is the most commonly used private placement exemption in the United States. It allows companies to raise an unlimited amount of capital from accredited investors without SEC registration. Reg D has several sub-rules, but two dominate startup fundraising: Rule 506(b) and Rule 506(c).

Rule 506(b): Allows raises from up to 35 non-accredited but sophisticated investors plus an unlimited number of accredited investors. No general solicitation — meaning you cannot advertise publicly or reach out to investors you have no prior relationship with. This is the traditional private placement used for angel rounds, seed rounds, and Series A/B/C raises.

Rule 506(c): Allows general solicitation (public advertising, cold outreach, online listings) but requires that every investor who actually invests is verified as accredited. Verification must be documented — a self-certification checkbox is not sufficient. Third-party verification services cost $50–$200 per investor. 506(c) is used when issuers want to market broadly but are comfortable with an all-accredited investor base.

Who qualifies as an accredited investor?

Under SEC rules, an accredited investor is an individual who meets at least one of these criteria:

What does a Reg D raise require?

Filing: Companies file a Form D notice with the SEC within 15 days of the first sale. Form D is short (two pages) and is not reviewed by the SEC — it is a notice, not an application. There is no pre-approval process.

Private placement memorandum (PPM): Reg D does not legally require a PPM, but virtually every competent securities attorney will require one to be prepared. A PPM is the disclosure document investors receive. It describes the company, the securities, the risks, and the use of proceeds. Skipping it creates significant legal exposure.

No ongoing SEC reporting: After closing, Reg D issuers have no mandatory SEC reporting requirements (unless they later cross thresholds that require Exchange Act registration). This is the lowest ongoing compliance burden of the three exemptions.

What does Reg D cost?

Legal fees for a Reg D offering typically run $10,000–$50,000 depending on complexity of the PPM and deal structure. There are no platform requirements, no audited financial requirements (though investors will often ask for them), and no FINRA portal fees. Reg D is the lowest-cost exemption to execute, which is why it dominates angel and institutional fundraising.

Real Reg D Example

Company: A SaaS company with $1.2M ARR raising a $2M seed round from angel investors and one small institutional fund.

What happened: The company used Rule 506(b), meaning no public advertising. They raised from 12 accredited investors they had existing relationships with — former colleagues, angel networks, and one fund the founder had been introduced to. The raise took 6 weeks from first conversation to close. Legal cost was $22,000 for the PPM and subscription agreements. No platform fees. Net proceeds: $1.978M.

Outcome: Fast, clean, low-cost. The company gave up roughly 18% equity. Because the investors were all accredited and there were fewer than 35 total, they had no ongoing SEC reporting requirements. The trade-off: the company's investor pool was limited to people they already knew or could be introduced to. They left a potential community-building opportunity on the table.

KEY DIFFERENCES

🔍 The 6 Most Important Differences Founders Get Wrong

1. "Accredited only" vs. "everyone." Reg D is accredited investors only (with a narrow exception for sophisticated investors under 506b). Reg CF and Reg A+ allow retail investors. If your target investors are everyday people who love your product, Reg D is the wrong exemption. If you are raising from angels and funds, Reg CF and Reg A+ add compliance overhead you may not need.

2. General solicitation rules differ by sub-rule. Reg CF allows full public advertising. Reg A+ allows full public advertising. Reg D Rule 506(c) allows public advertising but requires verified accredited investors. Reg D Rule 506(b) prohibits general solicitation entirely — which means no LinkedIn posts, no Twitter announcements, no cold emails to investor lists.

3. SEC qualification vs. SEC filing vs. SEC notice. Reg A+ must be qualified by the SEC before you can accept money — this takes 3–6 months. Reg CF requires a Form C filing before launch, but the SEC does not review or approve it — you can typically launch within 3–6 weeks. Reg D requires only a Form D notice filed within 15 days of first sale — meaning you can close a deal before you file anything.

4. The minimum raise mechanics are different. Reg CF has a mandatory minimum target (a "target offering amount") and funds are held in escrow until it is hit. Reg A+ and Reg D do not require a minimum and can close on a rolling basis — you can take investor money the day it is committed.

5. Ongoing reporting burden is not equal. Reg A+ has the highest ongoing reporting burden (annual + semi-annual SEC filings). Reg CF has moderate burden (annual report). Reg D has the lowest (no mandatory SEC reporting post-close). If you want to minimize compliance costs after your raise, Reg D wins. If you want to build a public track record and investor community, Reg CF or Reg A+ are better fits.

6. The investor relationship is different. Reg D investors are typically sophisticated, write larger checks, and expect board seats, pro-rata rights, and information rights. Reg CF and Reg A+ investors typically write smaller checks, have no governance rights unless specifically granted, and are more valuable as a community asset than as active participants in company decisions.

DECISION FRAMEWORK

✅ Which Exemption Is Right for Your Raise?

Use this framework to narrow down your options based on where you are as a company:

The last row is worth noting: companies can run a Reg CF campaign at the same time as a Reg D round. This is increasingly common — the Reg CF campaign builds community and validates demand while a parallel Reg D round closes with institutional or accredited investors. Space Funding has structured dozens of simultaneous raises across both exemptions.

COMMON QUESTIONS

💬 Frequently Asked Questions

Can I run a Reg CF and Reg D raise at the same time?

Yes. Companies can run a Reg CF crowdfunding campaign and a Reg D private placement simultaneously, as long as each offering follows its own rules independently. The Reg CF must go through a FINRA portal; the Reg D can close directly with accredited investors. There is no legal prohibition on running both at once, and it is increasingly common for growth-stage companies.

What is the difference between a Reg CF and a Reg A+ raise?

The two most important differences are the raising limit ($5M for Reg CF vs. $75M for Reg A+) and the SEC process (Reg CF is filed but not reviewed; Reg A+ requires full SEC qualification before you can accept money). Reg A+ costs significantly more in legal fees and takes 3–6 months longer to launch. Reg CF is appropriate for raises up to $5M; Reg A+ makes sense when you need more than $5M and can support the higher upfront cost and timeline.

Do I need a lawyer for a Reg CF raise?

Yes. While Reg CF has lower legal costs than Reg A+ or Reg D, you still need a securities attorney to prepare your Form C, review your financial statements, and ensure your offering documents comply with SEC rules. Attempting to file a Form C without counsel is a compliance risk. Expect to spend $5,000–$25,000 on legal fees depending on complexity.

What happens if my Reg CF campaign does not hit its minimum?

If a Reg CF campaign closes before reaching its stated minimum target offering amount, all investor funds held in escrow are returned in full. Investors pay nothing. The company receives nothing. You can relaunch a new campaign after a failed one, but you will need to update your Form C and restart the filing process.

Can foreign companies raise under Reg CF, Reg A+, or Reg D?

Reg CF and Reg A+ are available only to US-incorporated companies (or companies with their principal place of business in the US in some cases). Reg D is also restricted to US issuers in most cases, though certain foreign private issuers have used analogous exemptions. If you are a foreign company, you will generally need to form a US entity before accessing these exemptions.

What is the difference between equity and a SAFE under Reg CF?

Companies raising under Reg CF can offer equity (actual shares), SAFEs (Simple Agreements for Future Equity), convertible notes, revenue share agreements, or debt instruments. SAFEs are the most common instrument in early-stage Reg CF raises because they defer the valuation conversation until a future priced round. Equity rounds require a current valuation, which can be contentious at early stages.
