Form 1-A vs S-1: Reg A offering vs full IPO
On Form 1-A vs S-1, both are documents a company files with the US Securities and Exchange Commission (SEC) to sell securities to public investors. The difference is scale and weight. A Form 1-A runs a Regulation A offering, capped and lighter; a Form S-1 is the full registration for a standard IPO, uncapped and heavier. This guide compares Form 1-A vs S-1 across the cap, the disclosure, and the green light. It is not investment advice.
Definition
Form 1-A versus S-1
both take a company to public investors. Form 1-A runs a Regulation A offering, capped at $75 million in 12 months for Tier 2, with scaled disclosure. Form S-1 is a full IPO registration with no size cap and fuller disclosure. Source: SEC.
When is each used?
A company uses Form 1-A when it raises under Regulation A, a route built for smaller and earlier-stage issuers reaching the general public. It uses Form S-1 for a full public offering, the path most traditional IPOs take. The choice turns on how much the company wants to raise and how much disclosure and ongoing reporting it is ready to carry.
How do they differ?
The two forms cover the same goal, selling to the public, with different weight.
| What to check | Form 1-A | Form S-1 |
|---|---|---|
| Route | Regulation A (Reg A+) | Full registration |
| Raise cap (12 months) | Up to $75M (Tier 2) | No cap |
| Disclosure | Scaled | Full |
| SEC green light | Qualified | Declared effective |
| Ongoing reports | Tier 2 only (1-K, 1-SA, 1-U) | 10-K, 10-Q, 8-K |
$75M vs uncapped

Which one should you read?
Read whichever matches the raise. For a smaller company going public under Regulation A, the Form 1-A carries the terms. For a standard IPO, the S-1 does. Both sit next to the private-raise route, which leaves only a brief Form D. To find any of them, see how to search SEC EDGAR.

Frequently asked questions
What is the difference between Form 1-A and Form S-1?
Both let a company sell securities to the public. Form 1-A is used for a Regulation A offering, capped at $75 million in 12 months for Tier 2, with lighter disclosure. Form S-1 is a full registration for a standard IPO, with no size cap and heavier disclosure. Source: SEC.
Is Regulation A cheaper than a full IPO?
Regulation A is designed to be lighter than a full S-1 registration, with scaled disclosure and, for Tier 1, no ongoing SEC reporting. Whether that suits a company depends on how much it wants to raise and its reporting appetite. Form 1-A caps the raise; Form S-1 does not. Source: SEC.
Does the SEC qualify a 1-A or declare it effective?
The SEC qualifies a Form 1-A offering statement before sales, and declares an S-1 registration statement effective before sales. The labels differ but both are the green light to begin selling. Neither is an SEC endorsement of the offering. Source: SEC.
Are both filed on EDGAR?
Yes. Both Form 1-A and Form S-1 are filed on the SEC's EDGAR system and are free to read. Amendments appear as 1-A/A and S-1/A. Source: SEC EDGAR.
