Rule 10b5-1 plan vs Form 144: how they differ
On Rule 10b5-1 plan vs Form 144, the two are easy to confuse because they can both attach to the same insider sale, but they do different jobs. A Rule 10b5-1 plan is the pre-arranged trading plan that gives an insider a defense against insider-trading claims. A Form 144 is the notice an affiliate files with the SEC before selling restricted or control stock under Rule 144. One is a legal shield set up ahead of time; the other is a pre-sale disclosure. This guide compares Rule 10b5-1 plan vs Form 144, and it is not investment advice.
Definition
Rule 10b5-1 plan versus Form 144
are two things that can touch the same insider sale. The Rule 10b5-1 plan is a pre-arranged trading plan that defends against insider-trading claims. The Form 144 is a pre-sale notice an affiliate files before selling restricted or control stock under Rule 144. One protects; the other notifies. Source: SEC.
What does a Rule 10b5-1 plan do?
A Rule 10b5-1 plan is set up in advance, when the insider holds no material non-public information, and it fixes the amount, price, and timing of future trades. If it meets the conditions, including the cooling-off period the SEC added in its 2022 amendments, the later trades are protected even if the insider knows more by the time they run. It is about timing and intent, not about disclosure.
What does a Form 144 do?
A Form 144 is a notice, not a defense. When an affiliate plans to sell restricted or control securities above the reporting threshold, they file a Form 144 with the SEC first, stating how much they intend to sell and when. It exists so the market has notice that an insider sale is coming under Rule 144.

How the two compare
The clean way to hold them apart is defense versus notice, and before versus around the sale.

A single affiliate sale can involve all three records: the 10b5-1 plan behind it, the Form 144 before it, and the Form 4 that reports it afterward.

Reading them together
Because they overlap on the same sale, reading them together tells you more than either alone. A sale that runs off a 10b5-1 plan set months earlier, reported on a Form 4 with the plan checkbox ticked and preceded by a Form 144, is a routine, pre-committed disposal. For where the completed trade is reported, see what a Form 4 filing is, and for the whole process of following disposals, see how to track insider selling.

Frequently asked questions
What is the difference between a 10b5-1 plan and a Form 144?
A Rule 10b5-1 plan is a pre-arranged trading plan that gives an insider a defense against insider-trading claims. A Form 144 is a notice an affiliate files with the SEC before selling restricted or control stock under Rule 144. The plan is a legal shield; the Form 144 is a pre-sale disclosure. Source: SEC.
Can one sale involve both a 10b5-1 plan and a Form 144?
Yes. An affiliate can sell shares under a 10b5-1 plan and, because the same sale is a Rule 144 sale above the reporting threshold, also file a Form 144 before it, plus a Form 4 to report the completed trade. They answer different questions about the same transaction. Source: SEC.
When is a Form 144 required?
An affiliate must file a Form 144 when planned sales of restricted or control securities exceed 5,000 shares or $50,000 within a three-month period. Since 13 April 2023, Form 144 must be filed electronically on EDGAR. Source: SEC.
Which one shows the trade actually happened?
Neither confirms a completed trade on its own. A 10b5-1 plan is set up in advance and a Form 144 is a notice of intent to sell. The completed transaction is reported afterward on a Form 4, within two business days. Source: SEC.
