Read Schedule 13D or 13G to understand a person’s substantial ownership of a covered class—generally more than 5%—and, on Schedule 13D, the filer’s relevant plans or proposals. These are separate reporting regimes, not competing versions of the same form.
Quick comparison: what each filing tells you
| Filing | Who and what it covers | When to read it | Timing headline |
|---|---|---|---|
| Form 4 | Section 16 report of specified insiders’ reportable changes in beneficial ownership. Section 16 status includes directors and officers and, generally, beneficial owners of more than 10%. | You want to inspect a covered insider’s reported transaction or ownership change. | Covered transactions are generally reported within two business days after execution, subject to limited deferred-reporting exceptions described in SEC materials. SEC enforcement material. |
| Schedule 13D | Section 13(d) substantial-ownership report. Generally relevant after a person acquires beneficial ownership of more than 5% of a covered class, when that person is not eligible to use Schedule 13G. | You want to understand a large holder’s position and the plans or proposals disclosed in the filing. | Initial filing within five business days after the acquisition that triggers reporting; an amendment for a material change is due within two business days. The SEC staff says the initial clock runs from trade date. SEC staff interpretations; SEC rule announcement. |
| Schedule 13G | Section 13(g) route available only to filers meeting a specified institutional, passive-investor, or exempt-investor eligibility route. | You want to see a qualifying large holder’s reported position and understand the stated basis for using 13G. | Deadlines depend on filer category and the applicable rule. The revised deadlines became applicable beginning September 30, 2024; there is no single 13G deadline for every filer. SEC rule announcement. |
The more-than-5% and more-than-10% figures belong to different regimes. The first is the general threshold relevant to Schedule 13D/13G reporting; the second is one route into Section 16 status. A person may be covered by one regime, both, or neither, depending on status and facts. SEC staff interpretations; SEC enforcement material.

Which filing should you open first?
If you are tracking an insider’s transaction
Start with Form 4. It is the relevant place to look for a covered insider’s reportable ownership changes, including transactions. Check the reporting person, transaction and event dates, and the ownership information in the filing rather than relying only on a headline summary.
If you are assessing a large holder’s position or intentions
Start with the holder’s Schedule 13D or 13G. A 13D is especially useful when you want to review the filer’s disclosed plans or proposals as well as its ownership position. For either schedule, read the filing itself and any amendments; the latest position or disclosure may differ from an earlier report.

If you are trying to understand why a holder filed 13D or 13G
Read the schedule’s stated filing basis and certification. A filer cannot use 13G just because it prefers that form: the relevant eligibility conditions must be met. The SEC’s summary is that an investor with control intent files 13D, while qualifying exempt investors and investors without control intent may use 13G. The actual rule route and facts matter; “13G” does not simply mean a holder has no influence. SEC rule announcement; SEC staff interpretations.
How to tell Schedule 13D from Schedule 13G
Both schedules concern substantial beneficial ownership, but 13G is limited to qualifying routes under the rules; 13D is the general route when the filer is not eligible for 13G. The relevant route depends on the filer’s category and circumstances, not merely the size of the position.
Rank #2
- Qualified institutional investors: Certain institutional filers may qualify for a 13G route if they meet the applicable conditions.
- Passive investors: A passive route is not available when the filer has a purpose or effect of changing or influencing control, subject to the rule’s terms. SEC staff says an officer’s or director’s role will generally make reliance on the passive 13G route unavailable.
- Exempt investors: Some persons may qualify for an exempt-investor route under the applicable rule.
These categories are a guide to what to check, not a shortcut for deciding a real filing obligation. Group status, beneficial-ownership rules, derivatives, exemptions, and the filer’s role or purpose can affect the analysis. SEC staff interpretations.
Timing: the clocks are different
Schedule 13D
Under the SEC’s 2023 amendments, an initial Schedule 13D is due within five business days after the acquisition that creates the reporting obligation. An amendment reporting a material change is due within two business days. SEC staff interprets the initial period as running from the trade date when the trade triggers the obligation, rather than the settlement date. SEC rule announcement; SEC staff interpretations.

Rank #3
Schedule 13G
13G deadlines vary by the filer’s eligibility category and the applicable rule. The SEC says the amendments accelerated those deadlines and that the revised deadlines became applicable beginning September 30, 2024. Do not infer a universal due date from the schedule name alone; identify the filer category and check the current rule. SEC rule announcement.
Form 4
Form 4 has its own Section 16 clock. SEC enforcement material describes the general deadline for covered changes as two business days after execution, with limited circumstances allowing deferred reporting. That is not the same clock as Schedule 13D’s trade-date rule. Check the current Form 4 instructions and applicable exceptions before drawing a conclusion about a particular filing’s timeliness. SEC enforcement material.
How to read the filings without mixing up their signals
- Identify the filer and regime. Is the report from a director, officer, or more-than-10% owner for Section 16 purposes, or from a more-than-5% beneficial owner under Section 13? The thresholds are not interchangeable.
- Check what prompted the report. Form 4 generally reflects a transaction or another reportable ownership change. Schedule 13D or 13G reports substantial beneficial ownership and, where required, later changes under a different set of rules.
- Read the filing date alongside the event date. For 13D, the initial clock may start from trade date; for Form 4, the general rule described in SEC materials is measured from execution. For 13G, the applicable category determines the calendar.
- Review amendments. A filing is a snapshot under its own legal test. An earlier percentage or share count may no longer describe the reported position, and changes can trigger amendments under the relevant rule.
- Look beyond the headline share count. Beneficial ownership can involve indirect interests and derivative rights. The filing and applicable rule determine what is counted; a headline total alone may not tell the full story.
A sale does not, by itself, answer every question about a 13D filer’s continuing reporting obligations. SEC staff describes specific treatment for material changes and for a final amendment declaring that the filer has ceased to beneficially own more than 5%. Check the applicable rule and the filings in the sequence. SEC staff interpretations.

The SEC’s 2023 amendments shortened the initial Schedule 13D deadline from 10 days to five business days and set a two-business-day deadline for material-change amendments. The revised Schedule 13G deadlines became applicable beginning September 30, 2024. Structured, machine-readable Schedule 13D and 13G filings became required beginning December 18, 2024. The format change affects filing data and access; it does not change the basic choice of filing to read for a transaction versus substantial ownership.

When the distinction matters most
- You see an executive purchase or sale: check that person’s Form 4 for the reported transaction and ownership change.
- You see a fund or investor reported above 5%: check its Schedule 13D or 13G and determine which eligibility route it claims.
- You want to know whether a large holder may seek changes: review Schedule 13D’s disclosures about plans or proposals; do not treat a 13G label alone as proof of no influence.
- You are comparing two percentages: first establish which beneficial-ownership test, class, date, and filing regime each number uses.
For an actual compliance question, the result can depend on beneficial ownership, group status, derivative rights, transaction facts, exemptions, and filer category. The filing is useful evidence, but it is not a substitute for applying current SEC rules to the specific facts.
