Equity Compensation Planning: A Guide for High-Income Professionals

High-income professionals in medtech, medicine, and business ownership often hold more than one type of equity grant at once, and each type follows its own rules for vesting and taxation. Knowing which type (or types) you hold is the starting point for every other decision that follows.

RSUs (Restricted Stock Units) are a promise from an employer to deliver shares once a vesting condition, usually time, is met. Unlike an option, an RSU has no exercise price: once it vests, you simply receive the shares (or their cash equivalent), and the value received is taxed as income at that point. RSUs carry no risk of expiring worthless the way an option can, but they also offer no leverage if the stock appreciates before vesting.

ISOs (Incentive Stock Options) can only be granted to employees and must meet specific IRS qualification requirements, including limits on the value that can first become exercisable in a calendar year. When those requirements are met and shares are held long enough, gain on sale may qualify for capital gains treatment rather than ordinary income treatment. That favorable treatment is not automatic, and, as discussed below, exercising ISOs may create an alternative minimum tax obligation even before any shares are sold.

NSOs (Non-Qualified Stock Options) can be granted to employees, directors, and consultants alike, with fewer restrictions than ISOs. In exchange for that flexibility, the spread between the exercise price and the fair market value at exercise is taxed as ordinary income at exercise, regardless of whether the shares are sold. Only appreciation after exercise is eligible for capital gains treatment.

ESPP (Employee Stock Purchase Plan) programs let employees buy company stock, often through payroll deductions, at a discount to market price, subject to plan limits. Whether the resulting gain is taxed as a qualifying or disqualifying disposition depends on how long you hold the shares after purchase and after the offering began, and the two outcomes can produce meaningfully different tax results for the same shares.

Our equity compensation planning services start from an inventory of exactly which grant types you hold, since the planning that follows differs by type.

Because RSUs do not require an exercise, timing questions here mainly apply to options. Once vested, an option can typically be exercised any time before it expires, and the timing choice trades off differently depending on option type, cash available, and your view of the stock.

Early exercise, when a plan allows exercising options before they vest, generally requires filing an 83(b) election with the IRS within 30 days of exercise to start capital gains treatment on future appreciation from that early date. It also means paying the exercise cost, and potentially tax, on shares that could still be forfeited if employment ends before they vest, so it shifts risk earlier in exchange for a potentially lower tax basis later.

Exercising at vesting versus holding is the more common decision. Exercising promptly may limit how much the spread (and any related tax) can grow if the stock keeps rising, but it also commits cash and increases exposure to a single company's stock. Holding unexercised options preserves flexibility and caps downside to the option's value, but a stock decline before you exercise could reduce or eliminate the built-in value.

Market conditions and concentration risk, how much of your net worth already sits in one employer's stock through salary, vested shares, and outstanding grants combined, may both influence when exercising or selling makes sense. A rising stock can make holding feel appealing while quietly increasing concentration; a volatile or declining stock can make an unexercised option's remaining value uncertain. Neither condition points to one correct action for every household.

A large vesting or exercise event rarely sits in isolation on a tax return. It can push total income into a higher bracket for the year, which changes how several other year-end tools perform.

Tax-loss harvesting, selling an investment at a loss to offset capital gains realized elsewhere, may help offset gains generated by an equity sale, subject to the wash-sale rule and the $3,000 annual limit on offsetting ordinary income once losses exceed gains. Charitable bunching, combining several years of planned giving into one tax year, often through a donor-advised fund, is another tool some households use to offset a large equity income event with an equally large deduction in the same year, though the benefit depends on how your itemized deductions compare to the standard deduction.

Withholding management deserves separate attention. RSU vesting may trigger supplemental withholding at a flat rate that may not cover the full tax liability once the vest is added to salary and other income, and options exercised without a same-day sale generally have no withholding applied at all. Reviewing withholding against an estimate of the actual tax owed, rather than assuming the employer's default rate is sufficient, is one of the more overlooked steps in equity planning.

For years with a large vesting or exercise event, estimated tax payments may be worth planning for in advance, since waiting until the following April to address a withholding shortfall could also mean an underpayment penalty on top of the tax itself. Our tax planning for high-income earners article covers these year-end tools in more depth, and business owners who also hold equity in their own company may find additional context in our business exit planning article, since entity structure and equity treatment can interact at the time of a sale.
