Section 16 Insider Reporting Compliance Guide 2026

The landscape of Section 16 insider reporting changed fundamentally on March 18, 2026. For the first time in the Exchange Act's history, directors and officers of foreign private issuers (FPIs) must file public beneficial ownership reports with the SEC, following enactment of the Holding Foreign Insiders Accountable Act (HFIAA). If your company is an FPI, or you advise one, this guide covers every obligation you need to meet right now.

Key takeaway: The HFIAA extends Section 16(a) reporting to FPI directors and officers, but explicitly leaves Section 16(b) short-swing profit liability and Section 16(c) short-sale restrictions out of scope. FPIs are not fully equated with domestic issuers.

What Is Section 16 of the Exchange Act?

Section 16 of the Securities Exchange Act of 1934 requires insiders of companies with equity securities registered under Section 12 to publicly disclose their holdings and transactions. Historically, "insiders" meant directors, officers, and beneficial owners of more than 10% of a registered class at domestic issuers. FPIs were carved out entirely under Rule 3a12-3(b).

The HFIAA, signed into law on December 18, 2025 as part of the National Defense Authorization Act for Fiscal Year 2026, closed that carve-out for directors and officers. The SEC adopted final implementing rules on February 27, 2026, amending Rule 3a12-3(b) and Rule 16a-2 and updating the text of Forms 3, 4, and 5.

For a deep dive into the short-swing profit rules that FPIs remain exempt from, see SEC Section 16(b) Short-Swing Profit Rules: A 2026 Practitioner's Guide.

Who Is a Section 16 Reporting Person Under the HFIAA?

The HFIAA applies to directors and officers of FPIs with a class of equity securities registered under Section 12(b) or Section 12(g) of the Exchange Act. It does not extend to 10% beneficial owners of FPIs, which is a meaningful difference from the domestic issuer framework.

Who Qualifies as a Section 16 Officer?

Rule 16a-1(f) defines "officer" by function, not title. The covered group includes:

• President
• Principal financial officer
• Principal accounting officer (or controller, if no PAO exists)
• Any vice president in charge of a principal business unit, division, or function (sales, administration, finance)
• Any other person who performs a policy-making function for the issuer

This definition is identical to the "executive officer" definition used for Dodd-Frank clawback purposes under Rule 10D-1. FPIs that applied that definition broadly for clawback policies should revisit the list carefully: the right approach for clawback purposes may overcount for Section 16 purposes, or vice versa.

Who Qualifies as a Section 16 Director?

Section 3(a)(7) of the Exchange Act defines "director" as any director of a corporation or any person performing similar functions, whether the entity is incorporated or not. For FPIs with two-tier board structures (a supervisory board and a management board), the SEC has confirmed that the Section 16 definition may be broader than what Form 20-F captures under "board of directors," which typically refers only to the supervisory board. FPIs should apply consistent criteria for their director rosters for both Section 16(a) and the FPI eligibility test under Rule 3b-4.

Directors by deputization, where an entity exercises board influence through a designated representative, can also fall within scope.

Practical note: 10% beneficial owners of FPIs remain fully exempt from Section 16, including Section 16(a) reporting. This contrasts with domestic issuers, where 10% owners must file Forms 3, 4, and 5.

Section 16 Reporting Forms: Form 3, Form 4, and Form 5

FPI insiders must file the same three forms as domestic insiders. All filings must be submitted electronically through EDGAR and accepted by 10:00 p.m. Eastern time to receive that day's filing date.

For existing FPI insiders serving as of December 18, 2025, the SEC's HFIAA FAQ confirms that Form 3 was due on March 18, 2026. If a person was no longer a director or officer as of that date, no Form 3 was required.

For new appointments after March 18, 2026, Form 3 is due within 10 calendar days of becoming an insider. For FPI IPOs after March 18, 2026, Form 3 is due upon effectiveness of the Exchange Act registration statement.

What Goes on Form 4?

Form 4 covers all changes in beneficial ownership, including open-market purchases and sales, equity award grants, option exercises, vesting events, gifts, and sell-to-cover or tax-withholding transactions tied to equity compensation. A sale on Tuesday must be reported by 10:00 p.m. Eastern on Thursday.

For a detailed breakdown of which specific transactions trigger a Form 4, including the nuances around equity compensation events, see What Transactions Trigger a Form 4 Filing Under Section 16?.

A Note on Pre-March 18, 2026 Transactions

If an FPI had a class of equity securities registered under Section 12 before March 18, 2026, Rule 16a-2(a) does not require directors and officers to report on their first Form 4 any transactions that occurred before that date. However, if an FPI registers under Section 12 on or after March 18, 2026, Rule 16a-2(a) does apply, and the first Form 4 must include certain transactions from the six months prior to registration.

Section 16 Exemptions for FPI Jurisdictions

The HFIAA grants the SEC authority to exempt FPI insiders from Section 16(a) if the laws of a foreign jurisdiction impose "substantially similar" requirements. The SEC exercised that authority promptly, issuing two exemptive orders.

• The first order, dated March 5, 2026, established the initial qualifying jurisdiction framework.
• The second order, dated May 20, 2026, expanded the list of qualifying cross-jurisdictions.

Under the combined orders, directors and officers may be exempt from Section 16(a) reporting if the FPI meets both conditions:

1. The company is incorporated or organized in a qualifying jurisdiction.
2. The company is subject to a qualifying regulatory regime that imposes comparable insider reporting requirements, which does not need to be the same jurisdiction as incorporation.

The qualifying cross-jurisdictions listed in the May 20, 2026 order include Australia, Canada, Chile, India, the European Economic Area, the Republic of Korea (South Korea), Singapore, Switzerland, and the United Kingdom. FPIs should work with legal counsel to confirm whether their specific facts satisfy the exemption criteria, as the analysis is jurisdiction-specific and fact-intensive.

Separately, the SEC extended no-action relief for insiders of FPIs in countries directly affected by the conflict in Iran and the surrounding region. The deadline for those insiders was extended to May 29, 2026, from the original March 18 deadline, for filers whose ability to comply was materially affected by the direct effects of the conflict.

What FPIs Remain Exempt From: Sections 16(b) and 16(c)

This distinction matters enormously for compliance program design. FPI directors and officers are subject only to Section 16(a) reporting. They remain exempt from:

• Section 16(b): Short-swing profit disgorgement. A domestic insider who buys and sells (or sells and buys) company securities within any six-month window must disgorge the profit to the company. FPI insiders face no such liability.
• Section 16(c): Short-sale restrictions. Domestic insiders are prohibited from selling short the company's equity securities. FPI insiders are not subject to this rule.

Any future extension of Sections 16(b) or 16(c) to FPIs would require additional legislation or a separate SEC rulemaking. The February 27, 2026 final rules were deliberately limited to what the HFIAA required and did not go further.

Note that Form 4 and Form 5 instructions reference transaction codes tied to Rule 16b-3 and other Section 16(b) rules. The SEC clarified in the adopting release that FPI insiders should still use those transaction codes when applicable, notwithstanding their continuing exemption from Section 16(b) liability.

EDGAR Access: The Operational Bottleneck

For many FPI directors and officers, obtaining EDGAR filing credentials was the most urgent pre-March 18 task, and it remains the critical operational step for any new insider going forward.

The process requires filing a notarized Form ID with the SEC. The SEC typically takes an average of six business days to review and approve a Form ID application. With the launch of EDGAR Next, unenrolled filers with legacy credentials also needed to re-enroll, adding to the volume of applications the SEC processed in early 2026.

The SEC's HFIAA FAQ confirmed that, given the unusually large volume of Form ID applications submitted before March 18, 2026, staff would not recommend enforcement action for untimely filings caused solely by lack of EDGAR access, provided the person submitted a completed Form ID application before March 18, filed the required report after receiving access, and did so no later than April 1, 2026.

For new insiders going forward, the practical lesson is clear: start the Form ID process immediately upon appointment, not after.

EDGAR access checklist for FPI insiders:

1. Search the EDGAR Company Database to confirm whether the director or officer has an existing CIK number.
2. If a CIK exists, confirm whether the filer is enrolled in EDGAR Next. If not, a new Form ID is required to restore electronic access.
3. If the filer serves on the board of another SEC-registered company, coordinate EDGAR access with that company's team.
4. If the filer has never filed with the SEC, submit a Form ID application for a new CIK.
5. Allow at least two to three weeks for processing, particularly during high-volume periods.

Updated Form Fields for FPI Filers

The SEC updated Forms 3, 4, and 5 to accommodate FPI-specific reporting. Key changes include:

• Foreign trading symbol field: An optional field (Box 3a on Form 3; Box 2a on Forms 4 and 5) allows reporting of a second trading symbol for FPIs with securities trading in both U.S. and non-U.S. markets. When shares trade in both markets, both symbols should be included.
• Postal code and country code fields: Each form now includes optional fields for a postal code and a country code as part of the reporting person's address, with a flag for non-U.S. locations.

These fields became available on March 18, 2026. Forms 3 submitted before that date could not include the new items.

Building Your Section 16 Compliance Program for FPIs

For FPIs now operating under Section 16(a), the compliance infrastructure that domestic issuers have built over decades needs to be stood up quickly. Here is a practical framework:

1. Identify and document your Section 16 insiders. Map your directors and officers against Rule 16a-1(f) and Section 3(a)(7). Cross-reference your Form 20-F senior management list, your clawback policy roster, and your two-tier board structure (if applicable). Document the analysis.

2. Confirm or obtain EDGAR credentials. For every current director and officer, verify CIK status and EDGAR Next enrollment. For incoming insiders, build Form ID submission into your onboarding checklist.

3. Establish transaction reporting workflows. Directors and officers need a clear channel to notify the compliance team of any transaction in company securities before or immediately after execution. Two business days is a short window. Coordinate with securities brokers to ensure timely notification.

4. Update your insider trading policy. Section 16(a) reporting obligations should be reflected in the policy. Pre-clearance procedures, blackout periods, and reporting obligations all need to account for the new two-business-day Form 4 deadline.

5. Assess the jurisdiction exemption. If your FPI is incorporated in or subject to the regulatory regime of a qualifying jurisdiction under the SEC's exemptive orders, work with counsel to confirm whether the exemption applies and document that analysis.

6. Prepare for real-time equity compensation disclosure. Under Section 16(a), every equity award grant, vesting event, and option exercise must be reported on Form 4 within two business days. This is a significant change from the aggregate compensation disclosure previously required on Form 20-F. Investor relations and legal teams should anticipate increased public visibility into individual compensation.

For questions about which specific transactions are exempt from Form 4 reporting, Section 16 Exemptions: Which Transactions Do Not Require a Form 4 and Why covers the Rule 16b-3 exemptions and other carve-outs in detail.

FAQ: Section 16 Insider Reporting for FPIs

Do 10% beneficial owners of FPIs have to file Section 16 reports? No. The HFIAA applies only to directors and officers of FPIs. The SEC's final rules under Rule 16a-2 explicitly exclude 10% holders of FPI equity securities from Section 16(a) obligations. This differs from the domestic issuer framework, where 10% owners must file.

Are FPI insiders subject to short-swing profit liability under Section 16(b)? No. The HFIAA amended only Section 16(a). FPI directors and officers remain exempt from Section 16(b) short-swing profit disgorgement and Section 16(c) short-sale restrictions. Any extension of those provisions to FPIs would require new legislation or a separate rulemaking.

When is Form 3 due for a director appointed after March 18, 2026? Within 10 calendar days of becoming a director or officer. For FPI IPOs after March 18, 2026, Form 3 is due on the day the Exchange Act registration statement becomes effective.

Can FPI insiders file Section 16 forms on paper? Only if the filer has obtained a hardship exception under Regulation S-T Rule 202. All other filings must be submitted electronically through EDGAR and accepted by 10:00 p.m. Eastern time to receive that day's filing date.

What is the deadline for Form 4 if a transaction occurs on a Friday? Two business days after the transaction. A Friday trade must be reported by 10:00 p.m. Eastern on Tuesday (assuming no intervening holidays).

Does a director of an FPI need to report transactions that occurred before March 18, 2026? Generally no, if the FPI already had a class of equity securities registered under Section 12 before March 18, 2026. Rule 16a-2(a) does not require retroactive reporting in that case. The look-back obligation applies only to FPIs that first register under Section 12 on or after March 18, 2026.

The HFIAA marks a genuine shift in how global capital markets transparency works. FPIs that build robust Section 16(a) compliance programs now, rather than treating it as a one-time filing exercise, will be better positioned as the SEC's attention to FPI disclosure parity continues to grow.
