Schedule 13G Filing Requirements: 2026 Practitioner Walkthrough

Schedule 13G is the short-form beneficial ownership report any person or group must file with the SEC once they cross 5% of a Section 12-registered equity class. The 2023 amendments to Regulation 13D-G, fully operative since September 30, 2024, rewrote every major deadline and eliminated the annual February 14 amendment that the market had relied on for nearly five decades. If your compliance calendar still references the old rules, it is wrong.

This walkthrough covers the mechanics that matter most in practice: which filer category you fall into, the exact deadline that applies, what triggers a quarterly amendment, the fund-vehicle eligibility trap, and what issuers must now do when the annual 13G amendment no longer arrives.

For the 13D vs. 13G choice itself, see the Schedule 13D vs. 13G comparison guide. For switching between forms once you have filed, see the 13G to 13D playbook and the 13D back to 13G walkthrough.

Who Must File Schedule 13G?

Any person or group that directly or indirectly acquires beneficial ownership of more than 5% of a class of equity securities registered under Section 12 of the Exchange Act must file either Schedule 13D or, if eligible, the shorter Schedule 13G. The obligation runs to individuals, institutions, and groups acting in concert.

Before calculating whether you have crossed the threshold, two mechanics matter:

• Options and warrants exercisable within 60 days count. Under Rule 13d-3(d)(1), an investor holding less than 5% of outstanding shares but with in-the-money options that would push them above 5% on exercise must include those instruments in the calculation.
• Treasury shares are excluded from the denominator. Section 13(d)(4) of the Exchange Act excludes shares held by or for the account of the issuer or a subsidiary, even if not formally retired. Repurchased shares sitting in a buyback program do not count as outstanding for your percentage calculation, per the SEC's Division of Corporation Finance CFIs (last updated September 2, 2026).
• ADRs are not a separate class. If you own more than 5% of outstanding ADRs but those ADRs represent 5% or less of the underlying Section 12-registered equity class, no filing is required. The reporting obligation is determined by ownership of the deposited securities class, not the ADR wrapper.

The Three Schedule 13G Filer Categories

Schedule 13G is available to three distinct categories of filers under Release No. 33-11180, each with different eligibility tests and different deadlines. Getting the category wrong is not a technicality; it determines whether your filing is timely.

The QII Eligibility Trap for Fund Vehicles

This is the most common structural error in fund compliance. A limited partnership, LLC, or other fund vehicle cannot file as a QII simply because its general partner or investment manager is a registered investment adviser. The fund entity itself must qualify as one of the institution types listed in Rule 13d-1(b)(1)(ii). A Delaware LP that is not independently a registered investment company, ERISA plan, or other listed type does not qualify as a QII, regardless of who manages it.

The practical consequence: many fund vehicles that have historically filed as QIIs should be filing as Passive Investors, which carries a significantly shorter initial filing deadline (5 business days vs. 45 days after quarter-end) and more demanding amendment obligations at high ownership levels. Review the entity-level qualification, not just the manager's status.

Separate accounts managed by a registered investment adviser can qualify as QIIs if the adviser files on behalf of the account and the account itself meets the ordinary-course and no-control-purpose tests. Sub-advised funds require the same entity-level analysis.

The Exempt Investor Category in Detail

Exempt Investors are most commonly pre-IPO shareholders: founders, early employees, and venture investors who held shares before the issuer registered the class under Section 12. The category is frequently underused because its mechanics are less well known.

Key points:

• No control-purpose certification is required. Unlike QIIs and Passive Investors, an Exempt Investor is not required to certify that shares were acquired or held without the purpose of changing or influencing control. The SEC CFIs confirm this explicitly.
• The 2% acquisition limit has a 12-month look-back. To remain eligible, the investor must not have acquired more than 2% of the class in the 12 months preceding the most recent acquisition. If the Form 10 became effective less than 12 months ago, the look-back period runs to the time when the issuer was privately held.
• Adding a new group member can destroy eligibility. If a group relying on Rule 13d-1(d) adds a new member who beneficially owns more than 2% of the same class, the group is deemed to have "acquired" those securities. The entire group loses Exempt Investor status and must file on Schedule 13D, per the SEC CFIs.
• Stock-for-stock mergers do not qualify. A target shareholder who receives more than 5% of an acquiring company's Section 12-registered equity in a registered exchange merger cannot rely on the Section 13(d)(6)(A) exemption. That exemption covers only the issuer's own acquisition. The target shareholder must file Schedule 13D or, if eligible, Schedule 13G.

Schedule 13G Filing Deadlines: The 2026 Matrix

All deadlines below reflect the amended rules operative since September 30, 2024. The pre-amendment deadlines (10 calendar days, annual year-end amendments) are gone.

Key takeaway: The annual Schedule 13G amendment obligation no longer exists. There is no February 14 deadline. All amendments are now triggered by material changes during a calendar quarter, with the amendment due 45 days after that quarter-end, per Skadden's September 2024 client alert.

How to Count the Deadlines in Practice

A few mechanics that trip up compliance teams:

1. Business days, not calendar days. The 5-business-day and 2-business-day deadlines exclude weekends and federal holidays. A Passive Investor who crosses 5% on a Monday has until the close of business on the following Monday (five business days later) to file, assuming no intervening holidays.
2. Quarter-end is the measurement date for QIIs and Exempt Investors. A QII whose position exceeds 5% intra-quarter but falls back below 5% by quarter-end has no initial filing obligation for that quarter. The obligation attaches only if the position exceeds 5% as of the last day of the calendar quarter.
3. The 10% trigger is a month-end measurement for QIIs. If a QII's position exceeds 10% at any point during a month but falls below 10% by month-end, the accelerated 5-business-day deadline does not apply. For Passive Investors, the 10% trigger is event-driven, not month-end: crossing 10% at any point starts the 2-business-day clock.
4. EDGAR accepts filings until 10:00 p.m. Eastern time. The 2023 amendments extended the EDGAR cut-off from 5:30 p.m. to 10:00 p.m. Eastern under Rule 13(a)(4) of Regulation S-T. Teams racing a 2-business-day deadline have until 10:00 p.m. on the due date, not 5:30 p.m.

What Counts as a "Material Change" for Quarterly Amendments?

The SEC declined to define "material change" for Schedule 13G quarterly amendments, pointing instead to the general materiality standard under Rule 12b-2 and the "reasonable investor" test. This is a live compliance problem, not a settled one.

The SEC did note that Rule 13d-2(a), which deems a 1% or greater acquisition or disposition of beneficial ownership a material change in the Schedule 13D amendment context, is "instructive" for Schedule 13G filers, though not formally binding. TheCorporateCounsel.net's March 2025 analysis summarises the SEC's position: "While the SEC hasn't expressly defined what constitutes a 'material' change, it has pointed to the 'reasonable investor' test and Rule 13d-2(a) as instructive. Rule 13d-2(a) deems the acquisition or disposition of beneficial ownership of 1% or more of a covered class as a material change in the Schedule 13D amendment context."

A practical working framework for compliance teams:

• Likely material: a 1% or greater change in beneficial ownership percentage; a change in the filer's purpose or intent toward the issuer; a change in the identity of the reporting persons; acquisition or disposition of derivative instruments referencing the issuer's equity.
• Likely not material: routine portfolio rebalancing that moves the position by less than 1% with no change in intent; minor administrative corrections to contact information.
• Uncertain: position changes between 0.5% and 1% in a volatile quarter; changes in the composition of a group that do not affect aggregate ownership.

The safest posture: treat a 1% change as the floor for materiality and document the analysis for any change below that threshold where a reasonable investor might disagree.

For Passive Investors specifically, the 10% threshold amendment obligations (2 business days) are separate from and in addition to the quarterly material-change obligation. A Passive Investor who crosses 10% must file within 2 business days regardless of whether the change would otherwise be "material" under the quarterly standard.

Derivative Securities: What Schedule 13G Requires

The 2023 amendments clarified Item 6 of Schedule 13D to explicitly require disclosure of all derivative interests referencing the issuer's equity, including cash-settled instruments such as total return swaps and contracts for difference, even if those instruments do not constitute beneficial ownership under Rule 13d-3.

The distinction matters for 13G filers in two ways:

1. Beneficial ownership threshold. Whether a cash-settled derivative counts toward the 5% threshold is a facts-and-circumstances analysis under Rule 13d-3. A total return swap that gives the holder effective economic exposure but no voting or dispositive power over the underlying shares generally does not create beneficial ownership. But if the instrument provides, directly or indirectly, exclusive or shared investing power over the reference security, it may.
2. Disclosure obligation on Schedule 13D. If you are required to file Schedule 13D (not 13G), Item 6 requires disclosure of all derivative positions referencing the issuer's equity, including cash-settled instruments. Schedule 13G does not carry the same Item 6 disclosure requirement, but if a derivative position pushes you into Schedule 13D territory, the full disclosure obligation applies.

For a deeper treatment of cash-settled swaps and beneficial ownership, see SEC cash-settled swaps and beneficial ownership explained.

Structured Data: The XBRL Requirement Since December 2024

All Schedule 13D and 13G filings (other than exhibits) must be submitted in inline XBRL format, effective December 18, 2024. This is not a future obligation; it is a current requirement that applies to every filing made today.

In practice, this means:

• Filers must use the EDGAR Online Forms system, which supports inline XBRL tagging for Schedule 13D and 13G filings.
• The structured data requirement covers the body of the filing. Exhibits (such as joint filing agreements) are excluded.
• Filers who previously submitted plain-text or HTML filings without XBRL tagging must update their workflow. The EDGAR Filer Manual and 17 CFR 240.13d-102 govern the technical format requirements.

Teams that have not yet updated their filing templates since December 18, 2024 should treat this as an immediate remediation item.

How to File on EDGAR: The Mechanics

Schedule 13G and its amendments are filed through the EDGAR Online Forms system. The form type selection depends on what you are filing:

• Initial filing: select "Schedule 13G" as the form type.
• Amendment: select "Amendment to Schedule 13G." Have the accession number of the most recent prior filing ready; EDGAR requires it to link the amendment to the original.
• Switching to Schedule 13D: this is a separate filing workflow covered in the 13G to 13D switching playbook.

The EDGAR cut-off is 10:00 p.m. Eastern time. A filing accepted by EDGAR before 10:00 p.m. on the due date is considered filed on that date.

The Issuer-Side Problem: Proxy Tables Without Annual 13G Amendments

This is the gap that most competing content misses entirely, and it is a real operational problem for corporate secretaries and general counsel preparing proxy statements.

Before the 2023 amendments, issuers preparing the Item 403 of Regulation S-K beneficial ownership table for their proxy statement could rely on the annual Schedule 13G amendments filed by February 14 each year. Those amendments reflected year-end ownership positions and arrived reliably before proxy season. That filing no longer exists. As TheCorporateCounsel.net noted in March 2025: "All of the annual Schedule 13G amendments that we relied on each year to update the beneficial ownership table have disappeared, thanks to the SEC's 2023 amendments."

What issuers face now:

• The most recent 13G on file for a given institutional holder may be months old, reflecting a quarter-end position that predates the proxy record date by a significant margin.
• Instruction 3 to Item 403 of Regulation S-K permits issuers to rely on the contents of Schedules 13D and 13G, "unless the registrant knows or has reason to believe that such information is not complete or accurate or that a statement or amendment should have been filed and was not."
• That carve-out creates an affirmative obligation. If an issuer has reason to believe a filed 13G is stale, it cannot simply cite it in the proxy table without independent verification.

Key takeaway for issuers: Instruction 3 is not a blanket safe harbour. If you know or have reason to believe a major shareholder's position has changed materially since the last 13G was filed, you must exercise independent judgment, not just copy the last filing date into a footnote.

A second complication: Form 13-F data is not a substitute. SEC CDI Question 229.02 (Regulation S-K) makes clear that "investment discretion" (the 13-F standard) is not the same as "beneficial ownership" (the 13D/G standard). An investment manager may report a position on Form 13-F without that position constituting beneficial ownership for Item 403 purposes, and vice versa. Issuers cannot rely exclusively on 13-F data to identify 5% beneficial owners.

Practical steps for proxy season:

1. Pull all Schedule 13G and 13D filings for the issuer from EDGAR at least 60 days before the proxy filing date.
2. Note the date of each filing and the quarter-end it reflects.
3. For any holder whose last filing is more than one quarter old, assess whether a material change has likely occurred based on available market data (13-F filings, public trading data, press reports).
4. Where there is reason to believe a filing is stale, contact the holder directly or disclose the limitation in the proxy table footnotes with the date of the source report.
5. Do not rely on 13-F data alone to confirm or deny 5% beneficial ownership.

Group Formation: The Coordination Risk

The 2023 adopting release clarified that two or more persons can constitute a "group" under Sections 13(d)(3) and 13(g)(3) without an express written agreement. Concerted actions for the purpose of acquiring, holding, or disposing of securities can be sufficient.

This has direct implications for institutional investors who coordinate on proxy votes, engage jointly with management on ESG matters, or participate in shareholder campaigns. The SEC's guidance does not prohibit coordination, but it does mean that the aggregate beneficial ownership of coordinating parties must be assessed against the 5% threshold. If the group collectively exceeds 5%, a group filing obligation may arise.

For a full treatment of group formation mechanics and the practical boundaries of safe coordination, see the beneficial ownership group formation guide.

Losing Schedule 13G Eligibility

A Schedule 13G filer who loses eligibility must switch to Schedule 13D. The triggers differ by filer category:

• QII: develops a control purpose or effect, or ceases to hold in the ordinary course of business.
• Passive Investor: develops a control purpose or effect, or exceeds 20% beneficial ownership.
• Exempt Investor: acquires more than 2% of the class in any 12-month period (unless eligible as a QII or Passive Investor).

Once eligibility is lost, the filer must file Schedule 13D within 5 business days. The Schedule 13G passive investor eligibility walkthrough covers the eligibility tests in detail, and the 13G to 13D switching playbook covers the conversion mechanics.

FAQ

Who needs to file Schedule 13G? Any person or group that beneficially owns more than 5% of a Section 12-registered equity class and qualifies as a QII, Passive Investor, or Exempt Investor may file Schedule 13G in lieu of Schedule 13D. Investors who do not meet any of those three categories must file Schedule 13D.

How many days do you have to file a 13G? It depends on your filer category. QIIs and Exempt Investors have 45 days after the calendar quarter-end in which they first exceed 5% at quarter-end. Passive Investors have 5 business days after crossing 5%. If any filer's ownership exceeds 10% before the end of the quarter, a faster deadline applies: 5 business days after month-end for QIIs, 2 business days after the event for Passive Investors.

Is there still an annual Schedule 13G amendment due February 14? No. The 2023 amendments eliminated the annual amendment obligation entirely. All Schedule 13G amendments are now triggered by material changes during a calendar quarter, with the amendment due 45 days after that quarter-end. The February 14 deadline no longer exists.

What is the Schedule 13G filing deadline for 2026? For QIIs and Exempt Investors, the Q3 2026 initial filing deadline is November 14, 2026 (45 days after September 30). The Q3 2026 quarterly amendment deadline is the same date. For Passive Investors, the deadline is always 5 business days after the triggering acquisition, regardless of quarter.

Can a limited partnership file as a QII because its GP is a registered investment adviser? No. The LP itself must qualify as one of the institution types listed in Rule 13d-1(b)(1)(ii). A GP's or manager's QII status does not extend to the fund vehicle. An LP that does not independently qualify must file as a Passive Investor if it holds less than 20% without a control purpose.

What are the EDGAR filing instructions for Schedule 13G? File through the EDGAR Online Forms system. Select "Schedule 13G" for an initial filing or "Amendment to Schedule 13G" for an amendment. All filings must include inline XBRL tagging as of December 18, 2024. The EDGAR cut-off is 10:00 p.m. Eastern time. The SEC's how-do-I guide covers the technical submission steps.

What happens if I miss the Schedule 13G filing deadline? Late or missed filings expose the filer to SEC enforcement action, including civil monetary penalties, disgorgement of profits, and injunctive relief. The SEC has historically pursued enforcement actions for beneficial ownership reporting failures, particularly where late disclosure coincided with market-moving activity. Compliance officers should treat the 5-business-day and 2-business-day deadlines as hard stops, not aspirational targets.
