SEC Form 3 Filing Made Simple

Fast,accurate and compliant Form 3 filings using Form345.com's simple 5 step workflow

What is Form 3?

Form 3 is the initial statement of beneficial ownership filed with the SEC. Corporate insiders— directors, officers, and anyone holding more than 10% of a registered class of securities—must file it when they first become insiders.

  • Deadline: Must be submitted within 10 days of becoming an insider.
  • Why it matters: Ensures transparency under Section 16 of the Securities Exchange Act of 1934.
  • Common triggers: The Company goes public, or someone is newly appointed as a director/officer.

Why Form 3 Filing is Important

Form 3 isn’t just paperwork—it’s the foundation of insider reporting. Because it’s the very first disclosure made when someone becomes an insider, the accuracy of Form 3 sets the tone for all future filings (Forms 4 and 5).

Legal Obligation

The SEC strictly enforces the 10-day deadline. Late filings can lead to financial penalties and reputational damage for both the insider and the company.

Form 3 filings are often scrutinized during audits and investigations. A mistake at this stage can complicate compliance reviews later.

The information disclosed in Form 3 (initial ownership structure) becomes the baseline for all subsequent updates in Forms 4 and 5.
