Schedule 13D and 13G: Thresholds, 2024 Deadlines, and Filing

The filing rules for Schedule 13D and Schedule 13G require anyone who acquires more than 5% of a public company’s voting shares to disclose that position to the SEC, using the long-form Schedule 13D by default or the shorter Schedule 13G if the holder qualifies as a passive, institutional, or exempt investor. The deadlines were tightened by an SEC rule that took effect September 30, 2024, and most filers now work on a business-day clock rather than the older calendar-day one.¹

The 5% Threshold and What Counts as Ownership

The filing obligation is triggered when a person or group crosses 5% of a class of equity securities registered under Section 12 of the Securities Exchange Act.² The denominator is the total outstanding shares most recently reported by the company. The obligation reaches individuals, corporations, partnerships, trusts, and informal groups who coordinate their purchases.

Beneficial ownership is broader than what sits in your brokerage account. You are a beneficial owner of shares over which you have or share either voting power or investment power, meaning the ability to sell or otherwise dispose of them.³ Shares held through family trusts, partnerships, or managed accounts where you retain control all count.

You also count shares you can acquire within 60 days through options, warrants, or convertible securities.³ Those not-yet-exercised shares are treated as outstanding for your calculation but not for anyone else’s. Cash-settled derivatives like equity swaps generally do not create beneficial ownership because they carry no voting or disposition rights, though a Schedule 13D filer must still disclose them in Item 6.⁴

Group Filings

When two or more investors agree to act together regarding a company’s shares, the SEC treats them as a single person for beneficial ownership purposes, and their holdings are combined. The agreement does not need to be formal or written. Two investors who each own 3% and casually agree to coordinate proxy votes have created a 6% group with a filing obligation. Adding a new member who owns more than 2% of the class to an existing reporting group triggers a fresh filing, because the group is deemed to have acquired that member’s shares.⁵

Which Form Applies

Schedule 13D is the default. Schedule 13G is a shorter alternative that only certain filers can use, and misclassification is a common enforcement issue.

When Schedule 13D Is Required

If you cross 5% and have any intention of influencing the company’s management, board, or business direction, you file Schedule 13D.² Activist shareholders seeking board seats, pushing for a merger, or lobbying for changes in corporate strategy all belong on 13D. So do investors who are still considering such steps. The SEC reads “purpose” broadly.

Who Can Use Schedule 13G

Three categories of investors qualify for the short form:²

Qualified institutional investors, meaning registered broker-dealers, banks, insurance companies, registered investment companies, and investment advisers, who acquired the shares in the ordinary course of business and not to influence control.
Passive investors, meaning holders of more than 5% but less than 20% who certify that the shares were not acquired to change or influence control.
Exempt investors, meaning persons who held the shares before the company registered under Section 12 or are otherwise exempt from Section 13(d) filing requirements.

The “ordinary course of business” and “no intent to influence control” requirements drive most disputes. A passive holder who later decides to push for a board seat loses 13G eligibility and must switch to 13D.

Filing Deadlines Under the 2024 Rules

The SEC’s 2023 final rule compressed nearly every deadline, and the new timelines took effect September 30, 2024.¹

Schedule 13D

The initial filing is due within 5 business days after crossing 5%. Amendments are due within 2 business days of any material change.⁶

Schedule 13G

Deadlines vary by filer category:

Qualified institutional investors file the initial report within 45 days after the end of the calendar quarter in which ownership exceeds 5%. If ownership exceeds 10% at month-end, an accelerated filing is due within 5 business days after that month-end. After that, any month-end increase or decrease of more than 5% triggers another 5-business-day filing window.
Passive investors file within 5 business days of crossing 5%. If ownership then exceeds 10%, an amendment is due within 2 business days, and any later increase or decrease of more than 5% triggers a 2-business-day amendment deadline.
Exempt investors file within 45 days after the end of the calendar quarter in which ownership exceeds 5%, with quarterly amendments due within 45 days of quarter-end for any material changes.

The passive-investor initial deadline is the one that changed most, moving from 10 calendar days to 5 business days.¹

What Schedule 13D Requires You to Disclose

Schedule 13D asks for considerably more detail than the short form. You provide full legal name, address, and citizenship for yourself and any associated entities or group members. Filers with certain legal history involving securities, including criminal convictions or civil judgments, must disclose it.

The report requires a breakdown of the source of funds used for the purchase. If you borrowed, you identify the lender and describe the loan or credit agreement terms.⁷

Item 4, purpose of the transaction, is the heart of the filing. You must describe any plans or proposals relating to the company, including:⁷

Acquiring additional shares or selling existing ones
Pursuing a merger, reorganization, or liquidation
Selling or transferring a significant portion of the company’s assets
Changing the board of directors or management
Altering the company’s capitalization or dividend policy
Delisting the company’s securities from an exchange

Vague or incomplete purpose disclosures are a common target for SEC scrutiny. The filing must also state the exact number of shares beneficially owned, the percentage of the class, transactions in the shares over the past 60 days, and any derivative contracts referencing the company’s equity, including cash-settled instruments.

Amendments and Switching From 13G to 13D

A Schedule 13D amendment is required within 2 business days of any material change. An ownership swing of 1% or more in either direction is automatically material.⁶ Smaller changes can also qualify depending on circumstances, and a shift from a passive stance to an activist one is material even if your share count has not moved.

Schedule 13G eligibility ends in two main ways: your purpose changes, or a passive investor crosses the 20% ceiling. Either forces a switch to Schedule 13D within 5 business days, down from 10 calendar days under the prior rules.¹ During the transition, passive investors face a cooling-off restriction: no voting the shares and no additional acquisitions until 10 days after the Schedule 13D is filed.

How to File Through EDGAR

All Schedule 13 filings are submitted electronically through EDGAR.⁸ First-time filers need a Central Index Key (CIK) number, obtained by submitting Form ID through the EDGAR Filer Management site.⁹ The application requires a notarized authentication document signed by an authorized individual and designation of at least one account administrator. Companies and multi-member entities must designate two.

Watch the daily cutoff. Filings submitted by 5:30 p.m. Eastern Time on a weekday receive that day’s filing date. Anything submitted between 5:30 p.m. and 10:00 p.m. rolls to the next business day. The system does not accept filings outside the 6:00 a.m. to 10:00 p.m. Eastern window or on federal holidays. Against a 2- or 5-business-day deadline, missing the 5:30 cutoff by minutes costs a full day. Once accepted, the filing is publicly available on EDGAR almost immediately.

Penalties for Late or Missed Filings

The SEC has made beneficial ownership reporting a priority enforcement area and uses data analytics to identify late filers. In a September 2024 sweep, the Commission brought settled charges against 25 entities and individuals for delinquent filings. Civil penalties ranged from $10,000 to $200,000 for individuals and $40,000 to $750,000 for entities. Public companies that contributed to insider filing failures, or failed to report insider delinquencies, were charged $200,000 each.

Beyond monetary penalties, the SEC can seek injunctive relief ordering violators to stop further violations and to file corrected reports. Courts have authority to freeze voting rights or restrict further acquisitions when a filer has used delay to gain an unfair advantage. Enforcement actions are publicly posted, and institutional investors on the SEC’s delinquent filer lists face questions from their own clients and compliance committees.
