Exercise timing is a tax and liquidity decision

ISO exercise timing

ISO exercise timing depends on strike price, fair market value, expected income, AMT exposure, cash available for exercise and taxes, and whether you can hold long enough for potential long-term capital gain treatment.

When this workflow applies

Use an ISO timing workflow when approaching year end, when valuation changes, when leaving a company, or when deciding whether to early exercise.

Step-by-step workflow

Model the bargain element created by the exercise date you are considering.
Test smaller exercise quantities across tax years instead of assuming one large exercise is best.
Track the ISO holding-period dates for qualifying disposition treatment.
Plan cash for strike cost, possible AMT, and the risk of no immediate liquidity.

Common risks to check

Leaving a company can shorten the exercise window.
Exercise before liquidity can create tax risk without sale proceeds.
Selling too early can create a disqualifying disposition and change the tax result.
