What Is a Form 144? The 2026 Definitive Guide
Form 144 is the SEC-mandated notice a corporate insider must file before selling restricted or control securities under the Rule 144 safe harbor. If you are an officer, director, or 10%-or-greater shareholder of a public company, or a compliance officer advising them, this form sits at the intersection of securities law, insider trading rules, and EDGAR mechanics. Get it wrong and you are not looking at a technicality, you are looking at a potential Section 5 violation of the Securities Act of 1933.
Key takeaway: Form 144 is a pre-sale notice, not a post-trade report. It must be filed concurrently with placing the sell order, and filing it does not itself authorize the sale.
What Is Form 144 and What Law Requires It?
Form 144 is formally titled "Notice of Proposed Sale of Securities Pursuant to Rule 144 Under the Securities Act of 1933." It is the notice mechanism tied to Rule 144 (17 CFR §230.144), which provides a safe harbor from the registration requirements of Section 5 of the Securities Act. Without that safe harbor, selling restricted or control securities into the public market is an unregistered distribution, which is illegal.
The form captures six categories of information:
- The class and amount of securities proposed to be sold
- The manner of sale (broker, market maker, or riskless principal)
- The filer's relationship to the issuer
- Securities sold in the prior three months (to enforce the volume cap)
- Broker information
- The approximate date of the intended sale
The official SEC form document makes the filing obligation concrete: it is required when a proposed sale exceeds 5,000 shares OR $50,000 in aggregate market value in any three-month period. Whichever threshold is crossed first triggers the obligation.
Restricted Securities vs. Control Securities: A Critical Distinction
Most explainers skip this, but the distinction determines who is subject to Rule 144 and Form 144 in the first place.
Restricted securities are securities acquired in unregistered, private transactions directly from the issuer or an affiliate. Examples include shares received in a venture financing, a private placement, a PIPE transaction, or upon exercise of employee stock options. The restriction is about how the shares were acquired.
Control securities are securities held by an affiliate of the issuer, regardless of how they were acquired. An affiliate is anyone in a relationship of control with the issuer, which typically means a director, executive officer, or a shareholder who beneficially owns more than 10% of the class. A fund that, alone or with related funds, crosses the 10% threshold is generally an affiliate. The restriction here is about who holds the shares.
An affiliate can hold both: restricted securities (acquired privately) and control securities (any shares, however acquired). Both categories require Rule 144 compliance, including Form 144, before a public resale.
Who Must File Form 144?
The filing obligation applies to affiliates of the issuer, specifically officers, directors, 10%-or-greater shareholders, and family members or controlled entities whose sales must be aggregated with theirs.
The aggregation rule is one of the most common compliance traps. Under Rule 144, sales by an affiliate and sales by persons whose transactions must be aggregated with the affiliate's, including family members sharing a household and certain trusts or entities the affiliate controls, all count toward the three-month volume cap. A director cannot route sales through a family trust to sidestep the threshold.
Non-affiliates who hold restricted securities of a reporting company must satisfy the 6-month holding period before resale, but after 12 months they may sell without any volume, manner-of-sale, or current public information conditions, and without filing Form 144 at all, per the 2007 Rule 144 amendments (Release No. 33-8869).
For non-reporting company securities, the holding period remains 12 months, and paper filing is still permitted. The electronic mandate discussed below applies only to reporting-company securities.
The Four Rule 144 Conditions: What Form 144 Does Not Replace
Filing Form 144 is a necessary step, not a sufficient one. All four conditions of Rule 144 must be independently satisfied before the sale proceeds.
| Condition | What It Requires | Common Trap |
|---|---|---|
| 1. Current public information | Issuer must be current in Exchange Act periodic reports (10-K, 10-Q, 8-K) | If the issuer is delinquent in filings, the safe harbor is unavailable regardless of Form 144 |
| 2. Holding period | 6 months for reporting-company securities; 12 months for non-reporting companies | Clock starts on the date of full payment, not grant date |
| 3. Volume limitations | The greater of 1% of outstanding shares or average weekly trading volume over the prior 4 calendar weeks | Family members and controlled entities aggregate toward this cap |
| 4. Manner of sale | Brokers' transactions, direct with a market maker, or riskless principal transactions; broker cannot solicit buy orders | Structured or negotiated sales outside these channels do not qualify |
For a detailed walkthrough of how to calculate and document the volume cap, see Finrep's Rule 144 Volume Limitations: A 2026 Practitioner Walkthrough.
On the current public information condition: if the issuer has missed a 10-K or 10-Q filing, insiders cannot rely on Rule 144. Form 144 does not cure that deficiency. The safe harbor simply is not available until the issuer is current.
What Is the Purpose of Form 144?
Form 144 exists to give the SEC and the public advance notice that an insider intends to sell, creating a transparency check on insider activity. It is not a registration statement and it does not make the sale registered. It is a disclosure mechanism that sits alongside the Rule 144 safe harbor.
The SEC's investor.gov portal states it plainly: "A person filing a Form 144 must have a bona fide intention to sell the securities referred to in the Form within a reasonable time after the filing of the Form." That "bona fide intention" requirement has teeth. Filing Form 144 repeatedly and then not selling could attract SEC scrutiny. Compliance teams should document the intent at the time of filing and maintain records of the decision process.
The form must be filed concurrently with placing the order to sell with a broker, or executing a sale directly with a market maker. It is not a post-trade report. If the sale does not happen within a reasonable time, the form lapses and a new one must be filed before any subsequent sale.
Form 144 vs. Form 4: The Difference That Trips Up Insiders
This is the single most common point of confusion for insiders and compliance teams. The two forms serve entirely different legal purposes and operate under different statutes.
| Form 144 | Form 4 | |
|---|---|---|
| Statute | Securities Act of 1933 | Securities Exchange Act of 1934, Section 16(a) |
| Purpose | Pre-sale notice of intended sale | Report of actual completed transaction |
| Timing | Filed concurrently with or before placing the sell order | Filed within 2 business days of the transaction |
| Who files | Affiliates selling restricted or control securities under Rule 144 | Officers, directors, and 10%-or-greater shareholders (Section 16 insiders) |
| What it discloses | Proposed sale details, volume history, broker | Completed transaction: price, shares, transaction code |
| EDGAR system | EDGAR OnlineForms (XML-based) | EDGAR OnlineForms (XML-based) |
An insider selling shares typically must file both: Form 144 before or concurrent with the sale, and Form 4 within two business days after. They are not interchangeable and one does not substitute for the other.

The 2023 Electronic Filing Mandate: What Changed Operationally
Since April 13, 2023, all Form 144 filings for securities of reporting companies must be submitted electronically via EDGAR. Paper filings for reporting-company securities are no longer accepted. This was mandated by SEC Final Rule Release No. 33-11070, adopted December 22, 2022.
A subsequent amendment, Release No. 33-11159 (effective March 20, 2023), changed how Form 144 filings are disseminated on EDGAR. They are now treated as ownership/Section 16 filings, with dissemination extended to 10:00 p.m. Eastern time on the filing date.
The practical operational changes compliance teams need to know:
- EDGAR codes are now mandatory. Every filing person, including affiliated entities and individuals who may receive in-kind distributions, must have their own EDGAR filing codes. The application process can take anywhere from one day to two weeks depending on the SEC's backlog.
- The XML spreadsheet format replaced HTML. EDGAR HTML filings are no longer supported as of the EDGAR 22.3 release (September 19, 2022). The filing uses a specially structured XML-based spreadsheet with three sheets: "Securities Information," "Securities To Be Sold," and "Securities Sold In The Last Three Months."
- Sheet limits apply. A filer must submit 1 to 40 "Securities Information" sheets, 1 to 40 "Securities To Be Sold" sheets, and 0 to 200 "Securities Sold In The Last Three Months" sheets per filing, per the Workiva Form 144 FAQ.
- The approximate date of sale field is constrained. It must be no greater than the current date plus 10 business days and no less than the current date minus one calendar year.
- Brokers may need a power of attorney. Many full-service brokers will continue to file on behalf of clients, but now require EDGAR filing codes and, in some cases, formal powers of attorney and amended service agreements.
Filings are submitted through the EDGAR OnlineForms system at onlineforms.edgarfiling.sec.gov.
For non-reporting company securities, paper filing in triplicate remains permitted under 17 CFR §239.144.
Is Form 144 Publicly Available, and What Does It Signal to Investors?
Yes. All electronically filed Form 144 filings are publicly searchable on EDGAR. This is not incidental: the SEC's regulations explicitly state that the information "will be made a matter of public record" and that "any information given will be available for inspection by any member of the public."
Investors and analysts routinely monitor Form 144 filings as a leading indicator of insider sentiment. The logic is straightforward: an insider who files Form 144 is signaling an intent to sell, which the market often reads as a bearish signal, particularly when multiple insiders at the same company file in close succession. Washington Service and other data providers have built entire products around aggregating and analyzing Form 144 data.
A few nuances worth knowing:
- Form 144 is an intent to sell, not a completed sale. The insider is permitted but not required to sell within the 90-day window after filing.
- The form also discloses securities sold in the prior three months (Table II), which can confirm whether previously filed Form 144s were actually executed.
- For foreign private issuers, whose officers and directors are not required to file Form 4, Form 144 is often the only public source of insider transaction data.
Is Form 144 Bullish or Bearish?
A single Form 144 filing is generally read as a mildly bearish signal, but context matters significantly. An insider selling a small portion of a large holding for diversification or tax planning purposes carries different weight than a cluster of Form 144 filings from multiple senior executives at the same company in a compressed timeframe.
Analysts weight Form 144 signals alongside Form 4 completions (which confirm the sale actually happened), the insider's historical filing-to-sale conversion rate, and the company's broader disclosure picture. A Form 144 that is never followed by a Form 4 sale tells its own story.
What Happens If You Do Not File, or File Incorrectly?
Selling restricted or control securities without complying with Rule 144, including filing Form 144 where required, constitutes an unregistered sale of securities in violation of Section 5 of the Securities Act of 1933. The consequences are serious:
- SEC enforcement action
- Disgorgement of profits from the sale
- Civil penalties
- Potential criminal liability under Section 24 of the Securities Act
This is not a theoretical risk. The SEC has enforcement tools specifically designed to identify unregistered distributions, and Form 144 filings (or their absence) are part of the surveillance picture. A failure to file is visible precisely because the electronic mandate now makes all compliant filings publicly searchable on EDGAR.
For compliance teams at smaller companies: equity plan participants who received restricted stock are not automatically affiliates. Whether they are subject to Rule 144 and Form 144 depends on whether they meet the definition of affiliate, which turns on control, not just employment status. Legal counsel should make that determination before any sale.
Form 144 and 10b5-1 Trading Plans
Insiders increasingly use Rule 10b5-1 trading plans to pre-schedule sales when not in possession of material non-public information, providing an affirmative defense against insider trading claims. The SEC significantly tightened 10b5-1 plan rules in December 2022 (Release No. 33-11138), adding cooling-off periods: for officers and directors, the later of 90 days after plan adoption or the next quarterly earnings release, up to a maximum of 120 days.
A 10b5-1 plan does not eliminate the Form 144 obligation. If sales under the plan cross the 5,000-share or $50,000 threshold in any three-month period, Form 144 must still be filed concurrently with each sale (or the first sale in a series). The plan provides the insider trading defense; Form 144 provides the Securities Act resale notice. They operate in parallel.
Form 144 filings are also a useful data source for plan adoption dates, since the form captures when securities were acquired and under what arrangement.
Form 144 Compliance Checklist
Before an insider sells restricted or control securities under Rule 144:
- Confirm affiliate status. Is the seller an officer, director, 10%-or-greater shareholder, or a controlled entity or family member whose sales aggregate with one?
- Check the holding period. Has the seller held the securities for at least 6 months (reporting company) or 12 months (non-reporting company)?
- Verify the issuer is current. Are all Exchange Act periodic reports (10-K, 10-Q, 8-K as required) up to date? If not, the Rule 144 safe harbor is unavailable.
- Calculate the volume cap. Aggregate all sales by the affiliate and related persons over the prior three months. Confirm the proposed sale does not exceed the greater of 1% of outstanding shares or the average weekly trading volume over the prior four calendar weeks.
- Confirm the manner of sale. Is the sale through a broker's transaction, directly with a market maker, or as a riskless principal transaction? Is the broker prohibited from soliciting buy orders?
- Check the threshold. Does the proposed sale exceed 5,000 shares or $50,000 in aggregate market value over the three-month period? If yes, Form 144 is required.
- Obtain EDGAR filing codes. Confirm the filing person has active EDGAR codes. If not, apply immediately.
- Prepare the XML spreadsheet. Complete the three-sheet EDGAR XML template: Securities Information, Securities To Be Sold, and Securities Sold In The Last Three Months.
- File concurrently. Submit Form 144 via EDGAR OnlineForms at the same time as placing the sell order with the broker.
- File Form 4 after the sale. Report the completed transaction within two business days of execution.
FAQ
Who needs to file Form 144? Officers, directors, and 10%-or-greater shareholders of a reporting company, plus family members and controlled entities whose sales are aggregated with theirs, must file Form 144 when proposed sales in any three-month period exceed 5,000 shares or $50,000 in aggregate market value.
What is the Form 144 filing deadline? Form 144 must be filed concurrently with placing the sell order with a broker or executing a sale directly with a market maker. It is not filed after the sale. EDGAR accepts filings until 10:00 p.m. Eastern time; submissions after that time are treated as the next business day.
Is Form 144 the same as Form 4? No. Form 144 is a pre-sale notice filed under the Securities Act of 1933, while Form 4 is a post-transaction report filed under Section 16(a) of the Exchange Act within two business days of the completed sale. An insider typically files both.
Is Form 144 publicly available on EDGAR? Yes. All electronically filed Form 144 filings are publicly searchable on EDGAR. Since April 13, 2023, all filings for reporting-company securities must be submitted electronically, making the full universe of current filings publicly accessible in near real-time.
Does filing Form 144 authorize the sale? No. Filing Form 144 is a necessary condition for using the Rule 144 safe harbor, but all four Rule 144 conditions (current public information, holding period, volume limitations, and manner of sale) must be independently satisfied. The form is a notice, not a permission slip.
What is Form 144A? Form 144A is a different instrument entirely. Rule 144A is an SEC safe harbor that allows resales of restricted securities to qualified institutional buyers (QIBs) without SEC registration. It is not a form filed with the SEC; it is a transactional exemption. The two are frequently confused but serve entirely different purposes.
