The short answer: You might benefit from a 10b5-1 plan if a large portion of your wealth is tied to company stock, you are concerned about the appearance of insider trading, or insider trading rules make it difficult to place trades when you want to.
A 10b5-1 plan is often a good fit when you want to reduce concentration risk, create predictable liquidity, or remove emotion and timing pressure from stock sales. It may be less necessary if your equity exposure is modest or you already have flexibility around when you can trade.
We recommend not doing this alone. Working with a fiduciary financial advisor with deep knowledge around the complexities of 10b5-1 plans can help you design an effective plan that helps you better understand potential execution, tax, and compliance considerations.
When a large portion of your wealth sits in company stock, it’s natural to feel some tension when you’re ready to sell shares and diversify. It can be especially uncomfortable when your ability to place those trades is limited by insider-trading rules and company policies.
Beyond the concentration risk and tax complexity that comes with equity compensation, placing trades with knowledge of material non-public information (MNPI), or even just appearing to do so, may exposure you to regulatory scrutiny, which is why executives and other corporate insiders face additional limits.
In some cases, you may even find yourself restricted from selling during an open window when other employees are allowed to trade.
Enter 10b5-1 plans. When used thoughtfully, these plans may help create clarity and structure around stock sales, while supporting broader financial goals.
In this article, we’ll walk through what a 10b5-1 plan is, how it works, and how it can help reduce the risk of insider-trader allegations when used correctly.
What Is a 10b5-1 Plan?
A Rule 10b5-1 plan can support an affirmative defense to insider trading allegations, but only if the plan is entered into and operated in full compliance with SEC rules and in good faith. It does not eliminate regulatory risk.
A 10b5-1 plan is a pre-arranged trading plan that allows employees to sell company stock according to specific instructions set in advance.
The plan is established during an open trading window when you’re also not aware of any material, nonpublic information. Once in place, trades happen automatically if pre-set conditions are met.
The key part is that the plan is established without you exercising any further discretion or subsequent influence over how, when, or if the trades occur. In this way, a 10b5‑1 plan creates a clear separation between making a decision of when and what to sell and when those trades are actually executed.
This separation is what supports an affirmative defense against insider trading under SEC rules, so long as the plan’s conditions are met and the plan is operated in good faith.
Who Typically Uses 10b5-1 Plans?
10b5-1 plans are most common among people senior executives, board members, and other insiders who face tighter trading restrictions. They can also be useful for any employee who wants to avoid being limited to blackout periods or wishes to place trades in an automated, disciplined, systematic way.
These plans are especially helpful for those whose company stock ownership represents a large share of their overall net worth. In those cases, selling shares isn’t just a financial decision— it’s also a compliance exercise, and it’s important to have structure so you’re not forced to make decisions under pressure.
How a 10b5-1 Plan Actually Works
The process begins with designing the plan itself. This is where key decisions are made:
- How many shares will be sold
- Over what time period
- Under what conditions
Some plans follow a simple schedule of preset dates. Others use price targets or formulas to decide when shares should be sold.
The right structure may depend on goals, risk tolerance, and tax considerations. A fiduciary wealth management team familiar with equity compensation and tax strategy can help you build a plan that works for you.
Once the plan is adopted, SEC rules require a waiting period from the time the plan is submitted until any trades can actually be placed.
For directors and officers, it’s the later of 90 days or 2 business days after the issuer’s quarterly results disclosure (capped at 120 days). For everyone else, it’s generally 30 days.
This “cooling-off” period is meant to reinforce that the plan was created in good faith, without access to inside information actively influencing the price or performance.
After that, trades are executed automatically through your equity compensation brokerage account if/when all predetermined conditions have been met.
Why 10b5-1 Plans Exist in the First Place
At their core, 10b5‑1 plans are really about managing risk in two ways:
- From a regulatory standpoint, the plan helps demonstrate that trades weren’t influenced by inside information.
- From a planning standpoint, it introduces discipline and predictability into what can otherwise be an emotional and stressful process.
For many executives, these plans also provide a practical way to create liquidity. Stock sales can be coordinated to support cash needs, prepare for tax obligations, or meet diversification goals without requiring constant attention to trading windows or market headlines.
What’s Changed in Recent Years
In recent years, the SEC has increased its focus on 10b5-1 plans. New rules have added more structure, including the cooling-off periods we mentioned above, limits on overlapping plans (with limited exceptions, such as certain sell-to-cover arrangements), and additional disclosure requirements.
Where 10b5-1 Plans Can Go Wrong
A common pitfall is treating a 10b5‑1 plan as a one‑off solution instead of part of your broader financial strategy.
Taxes are another area where surprises can pop up if the timing of sales isn’t planned carefully. Depending on the type of equity involved, sales may result in ordinary income, capital gains, or both if strategic timing of stock sales isn’t taken into consideration.
Without coordination, it’s easy to sell too much too quickly, triggering unnecessary taxes, especially if taxable events outside of the 10b5-1 plan (for example, RSU vesting) aren’t taken into consideration.
It’s also common to sell too little, leaving portfolios overly concentrated and exposed to company-specific risk and/or missing opportunities to sell stock at advantageous tax rates.
Do You Need a 10b5-1 Plan?
You may want to consider starting a 10b5-1 plan if company stock plays an outsized role in your financial life. This is common for executives whose compensation is heavily equity-based or whose net worth has grown alongside the company’s success.
A plan can also be helpful if trading windows feel restrictive or stressful, or if selling shares has become something you delay because the process feels complicated or risky. In those cases, structure can be a relief.
On the other hand, if your equity exposure is relatively small or your liquidity needs are minimal, a formal trading plan may add more complexity than value. The decision isn’t about checking a box—it’s about alignment.
Before starting a 10b5-1 plan, it’s worth stepping back and asking a few bigger-picture questions:
- How dependent is your financial future on the performance of a single stock? Or asked another way, what percentage of your net worth is tied up in one stock?
- What role do stock sales play in funding taxes, lifestyle needs, or long-term goals? And related, what role would you like it to play?
- How comfortable are you navigating trading rules and market volatility on your own?
If those questions feel tough to answer, that’s usually a signal that more structure could help.
Final Thoughts
Ultimately, the question isn’t just should I start a 10b5-1 plan? It’s whether having a defined, compliant framework for managing company stock would make the way you manage company stock simpler, clearer, and more intentional.
For executives and insiders with meaningful equity exposure, a 10b5-1 plan may be appropriate—but only when the plan is designed to support long-term goals, not just to meet a technical requirement.
