# What Is Early Exercise?

> Early exercise lets an option holder buy and hold shares before vesting—often to start the capital gains clock and reduce future tax on appreciation.

**Early exercise** is exercising stock options before they vest—paying the strike price now to hold shares (subject to repurchase) rather than waiting until options fully vest.

## How it works

Standard options vest over four years; you exercise after vesting and owe ordinary income tax on the spread (fair market value minus strike) at exercise. With **early exercise** (if your plan allows), you exercise unvested options immediately.

You receive **restricted stock** for the unvested portion—the company can repurchase shares if you leave before vesting, usually at cost. You file an **83(b) election** with the IRS within 30 days of exercise to pay tax on the small spread today (often near zero at grant) instead of on larger spread at each vest date.

Example: granted 100,000 options at $0.10 strike when FMV is $0.10. Early exercise costs $10,000 cash. 83(b) taxes minimal income now. If the company exits at $10/share years later, long-term capital gains treatment may apply to the gain—subject to holding periods and AMT nuances. Consult a tax advisor.

## Why it matters

- **Operators:** Early exercise is a bet on company success with real cash at risk. If the company fails, you lose the exercise payment and any AMT paid.
- **Founders:** Offering early exercise attracts tax-savvy hires. Ensure plan documents, board approvals, and 83(b) instructions are clear.
- **Finance teams:** Track repurchase rights and cap table entries for unvested early-exercised shares separately.

## Common mistake

Missing the 83(b) deadline. The election must be postmarked within 30 days of exercise—no extensions. Without it, early exercise loses most tax benefits and can create worse outcomes than waiting.

## FAQ

### What is Early Exercise in simple terms?

You pay the strike price and own shares immediately, even though your options have not fully vested. Unvested shares stay subject to repurchase if you leave.

### Why does Early Exercise matter?

If you file an 83(b) election within 30 days, future upside may qualify for long-term capital gains instead of ordinary income tax on spread at vesting. It requires upfront cash and tax risk if the company fails.
