Quick recap of what stock options are: when you’re granted stock options as an employee, you have the right to buy shares of the company you are working for (or another company of the group) if you pay a certain price called exercise price or strike price, which usually correspond to the value of the shares at the time of grant.
Stock options are such a great motivation and retention tool because they usually come with what we call a vesting schedule.
⏳ Vesting means you can’t buy the shares straight away, you need to work for the company for a certain period of time before you can buy them, e.g. you can buy 1/4th of the shares after 1 year of service then gradually more over time until you can buy 100% of the shares (typically after 4 years).
If the company’s value goes up, you can buy the shares at a discount compared to their current value.
ℹ️ Let’s say that in 2021 John Doe received options to buy 100,000 shares of a Delaware C-Corp called Acme, Inc. at a strike price of 1$ each.
In 2023, the shares of Acme, Inc. are now worth 5$ each. If John Doe exercises, he would buy each share at a 4$ discount compared to their current value.
Both concepts are often mixed in practice. Although there are some similarities because both allow you not to wait until the regular end of your vesting schedule to buy shares, the comparison stops there.
To simplify, acceleration 🏎️ 💨 enables you to vest faster, typically when either the company you work for is being acquired (”single trigger”) or the company you work for is being acquired and that you’re fired as part of the acquisition (”double trigger”).
Early exercise enables you to buy shares before waiting for the end of your vesting schedule 👉 You could receive stock options on Day 1️⃣, and pay the strike price to buy the shares on that same day!
We said earlier that stock options were a great retention tool because they come with a vesting schedule. Why the hell would you, as an employer, want to allow your employees to early exercise then?
Here’s the trick: if you early exercise, you become a shareholder, but your employer still has the right to buy back the shares that haven’t vested yet. So there’s still a vesting schedule but it’s attached to your shares rather than to your options.
If you leave the company, your employer will generally have the possibility to repurchase the shares, typically at the same price as the one you’ve paid to buy them.
Like with many things that first seem absurd or useless until you have a closer look at them, the primary reason is money, and more particularly taxes.
Early exercise is also interesting in certain cases if your employee is based in the US, but this article is focused on non-US employees only.
To keep it short and simple, there are two different types of gains which are taxed with stock options:
1️⃣ When you exercise your stock options
Often, the difference between the value of the shares at the time you exercise and the strike price (sometimes called the “spread” or the “bargain element”) is taxed as salary income. Salary income is very often taxed at progressive income tax rates 👉 the more income you have, the more you’re taxed. Sadly, salary income is often the most taxed type of income.
2️⃣ When you sell the shares
Often, the difference between the price at which you sell the shares and the value of the shares at the time you exercised the stock options is taxed as capital gains. Capital gains are usually taxed at a flat rate, which is usually lower than the rates applicable to salary income.
1️⃣ Taxation at exercise
John Doe buys 100,000 shares valued at 5$, against a strike price of 1$.
Taxes = (100,000 x (5$ - 1$)) x 40% ▶️ 40% of 400,000$ = 160,000$
2️⃣ Taxation at sale
In 2025, John Doe sells the 100,000 shares now valued at 10$ each.
Taxes = (100,000 x (10$ - 5$)) x 10% ▶️ 10% of 500,000$ = 50,000$
👉 Total tax amount paid in Wonderland without early exercise = 210,000$
1️⃣ Taxation at exercise
John Doe buys 100,000 shares on the same day he receives the stock options. John Doe buys the shares at their current price of 1$ each.
Taxes = (100,000 x (1$ - 1$)) x 40% ▶️ 0$
2️⃣ Taxation at sale
In 2025, John Doe sells the 100,000 shares now valued at 10$ each.
Taxes = (100,000 x (10$ - 1$)) x 10% ▶️ 10% of 900,000$ = 90,000$
👉 Total tax amount paid in Wonderland with early exercise = 90,000$
