Reg A vs. Reg D: Which Exemption Fits Your Raise?

By Frederick M. Lehrer  ·  October 01, 2026

Most private companies raise money under one of two SEC exemptions: Regulation D or Regulation A. They solve different problems. Choosing the wrong one costs time, money, and sometimes the exemption itself.

Regulation D in Brief

Regulation D — usually Rule 506(b) or 506(c) — is the workhorse of private capital.

  • ›No limit on the amount raised
  • ›Investors: accredited investors (506(c): accredited only, verified; 506(b): plus up to 35 sophisticated non-accredited)
  • ›Advertising: prohibited under 506(b); permitted under 506(c) with verification
  • ›SEC review: none — file a Form D after the first sale
  • ›Shares: restricted; resale generally under Rule 144
  • ›Disclosure: a PPM is the norm

Regulation A in Brief

Regulation A, sometimes called a "mini-IPO," is closer to a public offering.

  • ›Limits: Tier 1 up to $20 million; Tier 2 up to $75 million in a 12-month period
  • ›Investors: the general public, with investment limits for non-accredited investors in Tier 2
  • ›Advertising: permitted, including testing the waters
  • ›SEC review: an offering circular on Form 1-A, reviewed and qualified by SEC staff
  • ›Shares: generally not restricted
  • ›Ongoing reporting: Tier 2 requires annual, semiannual, and current reports

Side by Side

| | Reg D (506) | Reg A (Tier 2) |

|---|---|---|

| Maximum raise | Unlimited | $75M / 12 months |

| Who can invest | Mostly accredited | Anyone (with limits) |

| SEC review | None | Yes |

| Time to launch | Weeks | Months |

| Cost | Lower | Higher (audit, review) |

| Resale | Restricted | Generally freely tradable |

How to Choose

Choose Reg D if your investors are accredited, you want speed, and you can live with restricted shares.

Choose Reg A if you want to raise from your customers or community, need broad advertising, or want a step toward a public market — and you can budget for audited financial statements, SEC review, and ongoing reporting.

The question I ask first is always the same: how will you find your investors? The marketing plan decides the exemption.

I discussed Regulation A in depth on the podcast: Regulation A-Plus: What the Mini-IPO Actually Costs You.
