SEC Regulation D vs Regulation A: Which Is Right for Your Capital Raise?

Regulation D and Regulation A are the two most common SEC exemptions companies use to raise capital without a full registered offering. They differ significantly in who can invest, how much you can raise, what you must disclose, and the ongoing reporting burden.

Dimension

Regulation D

Regulation A+

Max raise (per 12 months)	Unlimited (Rule 506b/c); $10M (Rule 504)	Tier 1: $20M; Tier 2: $75M
Who can invest	506b: Unlimited accredited + up to 35 sophisticated; 506c: accredited only	Tier 1 & 2: Anyone (including non-accredited investors)
General solicitation	506b: No; 506c: Yes (accredited only)	Yes — can advertise publicly
SEC filing	Form D (brief notice, not a full registration)	Form 1-A offering statement (must qualify before selling)
SEC review	No review — just file Form D	SEC reviews and qualifies the offering — takes months
Disclosure document	No formal requirement; best practice is a PPM	Offering circular required (like a mini-prospectus)
Ongoing reporting	None for most Reg D offerings	Tier 2: Annual (1-K) and semi-annual (1-SA) reports required
State preemption	506b/c: Federal preemption (no state blue sky)	Tier 1: State registration required; Tier 2: Federal preemption
Cost	Low — legal fees for PPM, Form D filing	Higher — audit requirement for Tier 2, offering circular legal fees
Time to close	Weeks (no SEC qualification needed)	3–6 months (SEC qualification process)

Key Differences

Reg D is faster and simpler — file Form D, no SEC review, close quickly. It limits you to accredited investors (Rule 506). Reg A+ allows non-accredited investors (great for consumer brands or community raises) but requires SEC qualification and ongoing reporting for Tier 2.

Who Must Comply with Both

Companies that want to do a Reg A test-the-waters campaign while maintaining a Reg D fallback
Issuers who closed a Reg D round and want to expand to non-accredited investors via Reg A

Common Questions

Which is better for a startup raising a seed round?

Regulation D Rule 506(b) is the standard for seed rounds — no SEC review, fast to close, unlimited raise amount, familiar to institutional investors and angels. Reg A+ is rarely used for seed rounds.

Can I advertise a Reg D offering on social media?

Only under Rule 506(c) — general solicitation is allowed, but you can only sell to verified accredited investors. Rule 506(b) prohibits general solicitation.

Do I need an audit for Regulation A?

Tier 2 Regulation A requires audited financial statements. Tier 1 does not, but state securities laws may require audited financials for state registration.
