Equity Compensation: How to Plan Around RSUs, Options, and ESPPs
Equity compensation can become one of the largest parts of your net worth and one of the easiest to mismanage. Here is how the pieces work and what to weigh before your next vesting date.
Equity compensation is pay delivered as company stock rather than cash, most often as restricted stock units (RSUs), stock options, or an employee stock purchase plan (ESPP). Each type is taxed differently and vests on its own schedule, so the planning question is rarely whether to hold company stock. It is how much, for how long, and how the taxes and concentration risk fit the rest of your financial plan.
What to know before you decide
- RSUs are taxed as ordinary income when they vest regardless of if you sell or not. The shares you keep are then subject to capital gains rules from that point forward.
- Stock options come in two forms, incentive stock options (ISOs) and non qualified options (NSOs), and the tax treatment differs sharply, including a possible alternative minimum tax exposure with ISOs.
- An ESPP often lets you buy company stock at a discount. The discount is a real benefit, but holding every share you buy quietly builds concentration.
- Concentration is the risk most people underestimate. When one company pays your salary and holds a large share of your net worth, a single stock carries outsized weight.
- The tax bill and the sell decision are connected. Planning the two together, ahead of vesting, usually beats reacting after the shares land.
Equity Compensation, explained
The three forms you are most likely to hold
Most equity compensation arrives as one of three types, and telling them apart is the first step because each one changes what you owe and when.
Restricted stock units (RSUs)
An RSU is a promise of company shares that become yours on a vesting date. When they vest, their full value counts as ordinary income that year, and your employer typically withholds some shares to cover part of the tax. Two things surprise people here. The withholding is often not enough to cover the full bill at higher incomes, and the shares you keep start their capital gains calculation at the vesting price, not at zero.
Stock options (ISOs and NSOs)
An option is the right to buy company stock at a set price. Non qualified options are taxed on the difference between the grant price and the market price when you exercise. Incentive stock options can be more favorable, but exercising them can trigger the alternative minimum tax, a parallel calculation that catches many people who exercise and hold. The choice of when to exercise is a planning decision with real tax weight, not just a market call.
Employee stock purchase plans (ESPPs)
An ESPP lets you buy company stock through payroll, often at a discount and sometimes with a lookback that prices the purchase off the lower of two dates. The discount is a genuine benefit. The quiet risk is that people enroll, buy every period, and never sell, so the position grows into a large and undiversified holding without a decision ever being made.
Company stock inside your 401(k): the NUA rule
If your 401(k) holds actual shares of your employer’s stock, a rule called net unrealized appreciation, or NUA, may matter more than anything else on this page. When you leave the company, the usual move is to roll the entire 401(k) into an IRA. For most assets that is the right call. For appreciated employer stock, it can be a costly reflex.
NUA lets you move the employer shares in kind into a taxable brokerage account instead of rolling them to an IRA. You pay ordinary income tax only on the cost basis, which is the value of the shares when they first went into the plan. The appreciation is then taxed at long term capital gains rates when you sell, which are generally lower than ordinary income rates. Roll the stock into an IRA instead and this treatment is gone for good, because every dollar that later comes out of the IRA is taxed as ordinary income.
The rules are strict. The full plan balance generally must be distributed in a single tax year following a triggering event such as leaving the company, and the employer shares must come out in kind. Because one wrong step forecloses the benefit permanently, this is a decision to think through carefully, and usually one to coordinate with your CPA, before you move anything.

Why concentration is the real conversation
When your employer pays your salary and also holds a large share of your investments, your financial life leans heavily on one company. If that company has a hard year, your income and your portfolio can feel it at the same time. This is not a prediction about any employer. It is a structural point about putting too much in one place. The planning work is deciding, in advance and on purpose, how much company stock you are comfortable holding and building a schedule to trim toward that target rather than deciding in the moment.
How this fits a plan
Equity compensation does not sit on its own. It touches your cash flow, because vesting events change your income in specific years. It touches your tax planning, because the timing of a sale or an exercise can move a tax bill. And it touches your long term allocation, because a large single stock position changes the risk of the whole portfolio. The most useful step is usually to write down what you hold, when it vests, and how it is taxed, then decide the sell and diversification plan before the next vesting date rather than after.

Equity Compensation FAQ
Do I owe tax on RSUs even if I do not sell them?
Yes. RSUs are generally taxed as ordinary income at their value on the vesting date, whether or not you sell. If you keep the shares, any gain or loss after that date is treated separately under capital gains rules.
Should I sell my company stock as soon as it vests?
There is no single right answer. Selling at vesting can reduce concentration and is often close to tax neutral for RSUs, since you already paid income tax on that value. Holding may fit if the position is small relative to your overall assets. The decision belongs inside your broader financial plan rather than being made share by share.
What is the alternative minimum tax and why does it come up with options?
The alternative minimum tax is a separate calculation that can apply when you exercise incentive stock options and hold the shares. It catches people off guard because the tax can be owed in a year when no shares were sold. Planning the timing of an exercise is how you avoid surprises.
How much company stock is too much?
There is no universal threshold, but the useful question is how much of your net worth you would be comfortable having depend on one company, given that the same company also pays your salary. Setting a target and diversifying toward it on a schedule is more reliable than deciding in the moment.
