Exercising stock options.
"Exercise now, or wait?"Both miss the point. The machinery underneath decides what you keep.
A big grant vests, or an IPO unlocks. The instinct is to exercise and sell, or to hold and hope. Both ignore the machinery underneath: the AMT, your bracket, the concentration, and the calendar.
The ripple
An exercise is one decision. It sets off a chain of tax and portfolio consequences that a single well-chosen year can't contain.
A large block of stock options is ready to exercise
ISO or NSO decides whether it's ordinary income or an AMT preference
The exercise can quietly trigger the alternative minimum tax
It stacks on the year's bracket and the 3.8% surtax
Exercising leaves a concentrated position in one company
A multi-year sell-down unwinds it deliberately, not all at once
Low-basis shares can fund charity or gifts instead of a tax bill
What you keep
One grant. Six decisions between exercise and what you keep.
Same grant, two outcomes
Uncoordinated
- Everything is exercised at once, and the AMT bill is a spring surprise.
- The position stays concentrated in one stock, undiversified by inertia.
- Shares are sold in a single high-bracket year.
- Charitable and gifting options for low-basis shares are never considered.
Coordinated
- The exercise is modeled against AMT and brackets before it happens.
- A multi-year sell-down (a 10b5-1-style plan) reduces concentration on purpose.
- Sales are spread across tax years to fill brackets, not spike them.
- Low-basis shares are routed to a donor-advised fund or gifts.
Same grant. A different share of it kept.
In the room: CPA, an equity-comp specialist, and the investment plan, across tax years, not one.
Financial decisions should not surprise one another.
