Early Exercise
The ability to exercise stock options before they have vested, typically combined with an 83(b) election to gain potential tax advantages.
What Is Early Exercise?
Early exercise is a provision in some stock option agreements that allows you to exercise your options before they have vested. Instead of waiting for options to vest over your vesting schedule, you can purchase the underlying shares immediately — even on your first day. The shares you purchase through early exercise are still subject to the company's repurchase right: if you leave before the shares vest, the company can buy back the unvested shares, typically at the price you paid.
How Early Exercise Works
The Mechanics
When you early exercise, you pay the exercise price for some or all of your unvested options and receive actual shares of stock. These shares are subject to a repurchase right that mirrors your vesting schedule. As shares vest over time, the repurchase right lapses, and those shares become fully yours.
For example, if you are granted 10,000 options with an exercise price of $0.25 per share, you could early exercise all 10,000 shares for $2,500 on day one. If you leave after one year with standard four-year vesting, 2,500 shares would be fully vested and yours to keep. The company would have the right to repurchase the remaining 7,500 unvested shares at $0.25 per share.
Not All Plans Allow It
Early exercise is not universally available. It is more common at early-stage startups and is specifically permitted (or not) in your stock option agreement. If your agreement does not include an early exercise provision, you must wait for options to vest before exercising them.
The 83(b) Election Connection
Why It Matters
Early exercise is almost always paired with an 83(b) election — a filing with the IRS within 30 days of exercise that tells the government you want to be taxed on the shares at their current value rather than their value when they vest. Without an 83(b) election, you would owe taxes on each vesting tranche based on the FMV at the time of vesting, which could be significantly higher than the exercise price.
The Tax Advantage
When you early exercise and file an 83(b) election at a time when the FMV equals or is close to the exercise price, the taxable amount is zero or near zero. This means you pay little or no tax at exercise. More importantly, the capital gains holding period clock starts immediately. If you hold the shares for more than one year after exercise, any future gain qualifies for long-term capital gains rates — which are significantly lower than ordinary income tax rates.
Practical Implications for Startup Employees
Ideal Timing
Early exercise is most advantageous when the company is at an early stage and the 409A valuation is low. The earlier you exercise, the smaller the spread between the exercise price and FMV, and the lower your tax burden. As the company grows and the 409A valuation increases, the tax benefit of early exercise diminishes.
Financial Risk
The primary risk of early exercise is that you are spending real money on shares that may ultimately be worthless. If the startup fails, you lose your investment with no recourse. You are also locking up capital that could be invested elsewhere.
Forfeiture Risk
If you leave the company before your shares fully vest, the company will repurchase your unvested shares — typically at the lower of your exercise price or the current FMV. You get your money back for those unvested shares, but you do not participate in any appreciation on them.
How It Relates to Exercising Stock Options
Early exercise is one of the most powerful tax planning tools available to startup employees. By purchasing shares when values are low and filing an 83(b) election, you can potentially convert what would otherwise be ordinary income into long-term capital gains. However, it requires upfront capital and a willingness to accept the risk of loss. Evaluate your financial position, your confidence in the company, and the current valuation before making this decision.
