Form 144: how insiders file notice of selling restricted stock

When an insider sells restricted securities, the SEC needs a heads up, and that notice is Form 144. It is an EDGAR filing, it is free, and for most startup teams it is the second SEC form they ever touch after Form D.

What Form 144 is

Form 144 is the notice of proposed sale of securities under Rule 144 of the Securities Act of 1933. An affiliate, meaning an officer, director, or holder of 10% or more of a class of equity, who sells restricted securities must file it to claim the Rule 144 safe harbor. Without the filing, the sale risks being treated as an unregistered distribution of securities, which is a far more serious problem than a missed form. The notice is filed with the SEC through EDGAR, has no filing fee, and must be filed before or at the time the sale is placed. See the Form 144 filing page for the calendar view and prep checklist.

The form itself asks for the issuer, the insider's relationship to it, the securities being sold, the number of shares, the estimated sale proceeds, and the market where the sale will occur. It also asks whether the seller has sold any of the issuer's securities in the prior three months, because the volume calculation depends on recent sales history.

Who has to file

The filing obligation attaches to two groups:

  • Affiliates: officers, directors, and holders of 10% or more of any class of equity securities. The rule captures control persons whether or not they hold restricted stock, because the SEC treats affiliate sales of any securities as potentially subject to Section 16 and Rule 144.
  • Sellers of restricted securities: anyone selling shares acquired in a private placement, an option exercise, a convertible note conversion, or another non-public transaction. A non-affiliate selling restricted stock of a reporting company can rely on Rule 144 without filing Form 144 once the holding period is met, but the broker still needs the compliance paperwork.

The distinction matters in practice. A founder selling shares they have held since founding is an affiliate, so they file Form 144 regardless of the size of the sale. An employee who bought shares in a seed round but holds no control position may be able to sell smaller amounts under Rule 144 without the filing, though the volume limits still apply.

The Rule 144 holding period

The core requirement of Rule 144 is a six-month holding period for restricted securities of a company that files reports with the SEC, and a one-year holding period for a non-reporting company. The clock starts when the securities were fully paid for, not when they were granted. That distinction matters for option holders: the holding period runs from the exercise date for the shares acquired, and from grant for certain qualified grants if the exercise price was paid up front in the form of an irrevocable election.

Holding-period tracking is where legal teams most often make mistakes, because each acquisition starts its own clock. A founder who exercises options in three separate tranches has three separate holding periods, and only the shares from the oldest tranche may be saleable today. The date the shares were paid for, not the date the option was granted, is the controlling fact.

Volume and manner of sale limits

An affiliate selling under Rule 144 must also respect the volume limit. The seller may not sell more in any three-month period than the greater of 1% of the outstanding shares or the average weekly trading volume in the four weeks before the sale. The sale must be in an "ordinary brokerage transaction," meaning no solicitation of buyers and a commission at normal rates. When the sale is placed, the Form 144 is filed with the SEC and the selling broker receives a copy, which is how the broker confirms the sale is compliant.

Filing mechanics on EDGAR Next

Form 144 goes through the same EDGAR Next pipeline as Form D. The seller needs a CIK and the EDGAR Next credentialing tied to a Login.gov account, then the structured filing is submitted and the SEC returns an accession number. It is the second form in LawDep's filing workflow for exactly this reason: the same credentials, the same pipeline, and a different template. A Form 144 triggered by an insider's sale shows up as an event filing on the compliance calendar, with the insider's entity details pre-populated from the register.

What happens if you sell without filing

The practical consequence is that the sale does not qualify for the Rule 144 safe harbor. The seller is left arguing that the sale was exempt another way, or that it was a non-distribution, which is a harder position to defend. The SEC has also focused on late and missing Form 144 filings in enforcement actions against insiders, particularly where the sales coincided with undisclosed company information. The form is cheap and fast, and the downside of skipping it is out of proportion to the effort.

Keep the calendar honest

Form 144 is event-driven, which means reminders do not come from a fixed date. They come from the sale event. LawDep surfaces the obligation when a restricted-sale transaction is logged, so the notice does not get lost between the broker, the lawyer, and the insider. Holding periods are tracked alongside, so a proposed sale can be checked against the oldest acquired shares before the paperwork starts.

How Form 144 interacts with Section 16

An affiliate who sells stock typically triggers a second filing obligation under Section 16 of the Securities Exchange Act. Officers, directors, and 10% holders must report their transactions on Form 4 within two business days of the trade, and the sale also reduces the insider's beneficial ownership, which is disclosed. The two filings are separate: Form 144 is the notice of intent to sell under Rule 144, and Form 4 is the Section 16 report of the completed transaction. A sale that generates both is common, and missing either one is an independent violation.

The Section 16 rules also add a wash-sale overlay: an insider who buys and sells within six months is exposed to short-swing profit disgorgement under Section 16(b). The Form 144 planner should therefore confirm not only the Rule 144 holding period but also the six-month window of Section 16(b), because the profit on a round-trip trade belongs to the company regardless of intent. Tracking the two calendars together is the difference between a clean sale and a compliance incident that lands on the annual proxy statement.
