Equity Compensation Triage for High Earners

Most high earners don't have one equity problem. They have four stacked on top of each other, and the order to work them is set by whichever clock expires first: the 83(b) window, then ISOs, then NSOs, then the concentration question. Without that order you get paralysis, or one-off decisions that conflict by tax time.

Start With What's Already Burning

The 83(b) election window closes 30 days after grant. If you hold restricted stock (actual shares, not RSUs) or early-exercised ISOs, that clock is already running. Missing it means owing ordinary income tax on all appreciation at vesting rather than at grant, often tens of thousands of dollars.

ISOs come next. Exercising creates no regular income tax, but the spread between exercise price and fair market value counts as an AMT preference item. In a high-income year, one where a bonus and RSU vests also land, a large ISO tranche can push you into AMT territory fast. A practical threshold: model the AMT impact before exercising if your total ISO spread for the year would exceed roughly $100,000. Spreading exercises across two tax years is often cleaner.

NSOs are simpler to understand but not simpler to ignore. The spread at exercise is ordinary income subject to payroll taxes up to the wage base, so timing relative to other income matters. A year where you're already in the 37% bracket is a different calculation than one where deferred compensation or a sabbatical opens a window at lower rates.

RSUs, ESPPs, and the Concentration Question

RSUs are taxed as ordinary income when they vest, whether you sell or not. Sell-to-cover, the common default, withholds shares for the tax and leaves you holding the remainder in one stock position, usually without a deliberate decision to hold it.

When a single stock position exceeds 10% of your net worth, you have concentration risk that warrants an explicit plan. Above 20%, the question isn't whether to diversify but how fast and through what mechanism. Tax considerations should inform the pace, not justify holding a dangerous position indefinitely.

ESPP shares add one more layer. The discount is taxed as ordinary income in the year of sale, with qualifying vs. disqualifying dispositions affecting the split. Holding for appreciation compounds concentration in the company that already pays your salary: two forms of human capital in one name. That is Soil-layer work, tax architecture before return optimization.

The Takeaway

The fact that sets your order is which clock runs out first, not which position is largest. A modest restricted-stock grant with 11 days left on its 83(b) window outranks a far bigger ISO tranche you can exercise any time in the next four years.

The people who get hurt are usually the ones handling each grant carefully in isolation. They exercise ISOs in the same year a large RSU tranche vests and a bonus lands, every decision defensible alone, then find in April that the combination created an AMT bill nobody modeled.

Sequencing four grant types across two or three tax years is worth a conversation before your next vest date.
