More jargon than substance
Equity compensation — restricted stock units, incentive stock options, non-qualified stock options — generates more anxiety than almost any other topic in personal finance. The jargon is dense, the tax treatment is intricate, and the stakes feel high because the amounts are often a large share of a household’s net worth. Strip away the jargon, however, and there are only four decisions that genuinely matter. Everything else is mechanics.
Decision one: when to exercise
The first decision is when to exercise options. Options give you the right to buy shares at a fixed price, but that right has a finite life and the tax consequences of exercising depend on the spread between the exercise price and the fair market value at exercise. Exercising early minimizes the spread (and therefore the tax) but ties up cash and risks paying for shares that may never appreciate. Exercising late maximizes the spread (and the tax) but preserves flexibility.
Decision two: when to sell
The second decision is when to sell the shares you acquire — whether from exercised options or from vested RSUs. The default for most recipients is to hold, partly out of loyalty and partly out of a reluctance to realize tax. Holding, however, leaves you with a concentrated position in the company that pays you, which is a risk concentration rather than an investment thesis.
Decision three: how to handle the alternative minimum tax
The third decision, specific to incentive stock options, is how to manage the alternative minimum tax. Exercising and holding ISOs can trigger AMT liability even though no regular tax is due, because the bargain element is an AMT preference item. This can produce a large tax bill with no cash from a sale to pay it.
Decision four: how to fund the exercise
The fourth decision is how to fund the exercise cost and the associated tax. Exercising options requires cash to buy the shares, and exercising and holding can require additional cash to cover the tax. The funding source matters: using cash you already have preserves the upside but concentrates your net worth further; a same-day sale (sell to cover) funds the exercise and tax from the proceeds but forfeits the upside on the sold shares; a margin loan preserves the shares but introduces leverage and its associated risks.
The mechanics, demoted
Once the four decisions are made, the mechanics — vesting schedules, holding periods for qualifying vs. disqualifying dispositions, the 83(b) election for early-exercised options, the interplay between regular tax and AMT — become implementation details. They still matter, and getting them wrong can be costly, but they are downstream of the decisions. A good tax professional can handle the mechanics; only you can make the decisions.
The bottom line
Equity compensation is complex in its mechanics but simple in its decisions. When to exercise, when to sell, how to handle the AMT, and how to fund the exercise are the four decisions that determine whether your equity comp becomes diversified wealth or a permanent concentrated bet. Make those four decisions deliberately, with professional help on the mechanics, and the rest of the jargon becomes manageable rather than menacing.
