Key takeaways

Equity compensation can be a chance to build wealth, but having a strategy may help you make the most of that opportunity.
Equity compensation usually isn’t actual ownership in the company until the award vests and/or you exercise.
Certain events can trigger a tax bill even if you haven’t received a dime in cash yet, so it’s important to understand and plan for the tax consequences of equity compensation.
Knowing when to sell your shares depends on a variety of factors that are unique to you.

Equity compensation is pay that comes as a piece of the company you work for, instead of (or on top of) cash. It’s a chance to own part of the business. Incentive stock options (ISOs), nonqualified stock options (NSOs), restricted stock units (RSUs) and employee stock purchase plans (ESPPs) are some of the most common types of stock-based compensation.

All kinds of employees may get equity comp: employees at startups, employees at public and private companies, executives — even sometimes contractors. Companies like it because it can help them hang on to cash, keep good people around and get everyone working toward the same goals. For employees, equity compensation can be an opportunity to build wealth by participating in the company’s potential success. However, there are a lot of things to plan for and understand to make the most of that opportunity.

How does equity compensation work? The general mechanics

There’s a lifecycle to equity compensation. It typically has four stages.

The grant. This is the company offering you the opportunity to own some of its shares, either outright or as the option to purchase them over time. You’ll get a grant document that outlines the conditions of the program, including how many shares you can get and exactly how and when you can get them.
Vesting. What happens at this stage depends on the type of equity involved. If you have stock options, vesting is when you gain the right (but not the obligation) to buy some or all of the shares in your grant. If you’ve got restricted stock units (RSUs), those shares are issued to you when they vest; you don’t need to pay for them.
Exercise or settlement. If you have stock options, this is when you actually buy the shares. The price you pay, called the exercise price or the strike price, is set in your grant. If the strike price is lower than what the shares are worth right now, your options are “in the money,” which means you could be getting a deal. If the strike price is above the current market value of the shares, the options are “underwater,” and buying would cost you more than the shares are worth. If you have RSUs, there’s nothing to buy; settlement is just when the shares are delivered to you.
Sale. This is when you eventually sell your shares, ideally for more than you paid for them.

What happens if I leave my job?

If you quit, get fired or are laid off, you may lose any shares that haven’t vested yet. Some companies may give employees a little extra time after they leave to exercise their options. Keep in mind that you may have to come up with the money to cover the strike price and withholding taxes, and if the company is private, you may have no way to sell.

Common types of equity compensation

Here’s a rundown of the most common forms of equity compensation.

Incentive stock options (ISOs)

An incentive stock option, or ISO, is the right (but not the obligation) to buy shares of company stock at a fixed price (called “the strike price”). Pre-IPO companies often issue ISOs. You have no ownership, no voting rights, no rights to dividends and no ability to sell the shares until you exercise the option. ISOs typically vest over time and expire after 10 years. ISOs usually aren’t taxed until you sell the shares. There’s one catch, though: exercising ISOs can sometimes mean owing alternative minimum tax (AMT), which is calculated under a parallel tax system intended to ensure high earners pay at least some income tax. Consulting with a financial advisor before you exercise can help avoid a surprise there.

Nonqualified stock options (NSOs)

A nonqualified stock option (NSO) works a lot like an ISO. You get the right to buy company shares at a fixed price. The difference is how it’s taxed. With NSOs, you typically owe income tax when you exercise the options and capital gains tax when you sell the shares. Similar to ISOs, until you exercise the option, you don’t own the shares and you can’t vote the shares, collect dividends from them or sell them.

Restricted stock units (RSUs)

With restricted stock units, there’s nothing to buy; the company gives you the shares once they vest. Before that, you don’t own the shares, can’t vote on shareholder matters, can’t receive dividends and can’t sell the shares. Typically, you owe income tax on the shares when they vest. (In the eyes of the IRS, vested RSUs are taxable income, even if you haven’t sold the shares.) You may owe capital gains tax when you sell the shares.

Employee stock purchase plans (ESPPs)

ESPPs are programs that allow you to buy company stock at a discount. The money goes directly from your paycheck into the plan’s account, which the plan then uses to buy company shares for you on a specified date. The amount of the discount varies by plan but can be as much as 15%. There’s usually a cap on how much you can buy each year. You may pay ordinary income tax on the discount (depending on the plan type and how long you hold) and capital gains tax on any profit you make from selling the shares.

Key things to know about taxes on equity compensation

Taxes are where equity compensation gets especially tricky and where a lot of people get caught off guard. The more you know ahead of time about what you might owe, the easier it is to plan around it.

You might encounter these taxes if you receive equity compensation.

Ordinary income tax: In 2026, these rates range from 10% to 37%, depending on the total amount of your taxable income. States have their own tax brackets. Some cities may also have a local income tax.
Capital gains tax: There are two types of capital gains tax. Short-term capital gains tax rates are the same as ordinary income tax rates. Long-term capital gains tax rates are either 0%, 15% or 20%, depending on your income, filing status and other factors. Typically, you must hold an investment for more than a year to get the long-term capital gains tax rate. States have their own capital gains tax rules.
Social Security and Medicare tax: These are in addition to income taxes and typically apply to RSU vesting and NSO exercises.
Net investment income tax (NIIT): This is a 3.8% tax that applies to capital gains if your modified adjusted gross income exceeds $200,000 ($250,000 if filing jointly).
Alternative minimum tax: AMT is a tax system that the IRS runs parallel to the standard tax system. It has different tax rates. The idea is to ensure that certain high-earning taxpayers pay at least some income tax.

Cheat sheet: Equity compensation taxation

Equity type	What you’re taxed on	When
ISOs	The difference between what you paid for the shares (the strike price) and what you sold them for. ISOs get capital-gains treatment only if you hold more than two years from grant and more than one year from exercise. Otherwise, some or all of the bargain element may be taxed as ordinary income. The bargain element is the difference between the strike price and the market value of the shares when you exercised.	Typically, when you sell the shares. AMT may be due in the year you exercise in some cases.
NSOs	The bargain element when you exercised, taxed as ordinary income. The bargain element is the difference between the strike price and the market value of the shares at exercise. When you sell, you owe capital gains tax on the difference between the sale price and the market value at exercise.	When you exercise and when you sell the shares.
RSUs	The value of the shares when they vest, and anything you get above the vest-date value when you sell.	When they vest and when you sell the shares.
ESPPs	The amount of the discount and the profit on the sale of the shares.	When you sell the shares.

Where things can get complicated

Here are some things to watch for if you’re receiving equity compensation.

Withholding tax

The IRS considers vested RSUs ordinary income, which makes them subject to withholding tax. Withholding tax is income tax that your employer withholds from your paycheck throughout the year and sends to the IRS or the state on your behalf. Employers commonly withhold a flat 22% on supplemental wages, which applies to RSUs. (That flat rate is higher if your supplemental wages cross $1 million.) Also, states with income taxes may require withholding.

So when your RSUs vest, expect some taxes to come out. That may actually help you avoid a surprise bill in April. And in many cases (check your employer’s plan), you don’t actually have to come up with the cash — you may be able to give back just enough of the vested RSUs to cover the withholding tax.

But withholding 22% may not be enough if you’re a high earner in a higher tax bracket. For example, if you have $100,000 of RSUs vest, the 22% (or $22,000) your employer withholds could fall short if you’re in the 35% tax bracket. In that case — and keep in mind, this is a very simplified example — your actual tax would be $35,000. You may have to come up with the extra $13,000 in April (and don’t forget — state and payroll taxes may apply, too). Because withholding often doesn’t match what you’ll actually owe, a financial advisor may be able to help you make a strategic plan for your RSUs.

Alternative minimum tax (AMT) traps

As mentioned, AMT exists to ensure that certain high-earning taxpayers pay at least some income tax.

For AMT purposes, the bargain element (the difference between the strike price and the market value of the shares when you exercise) counts as income. If that bargain element is big enough, exercising your options could land you with an AMT bill that you didn’t see coming. (When that happens, you may be eligible to take a special minimum tax credit against your regular tax in later years, though.)

There are a few ways to manage potential AMT exposure. For example, a qualified financial advisor can help you calculate how many shares you can exercise without crossing the AMT threshold and then exercise your options in batches over several years.

Unintentional concentration risk

Companies often grant equity compensation yearly as “refreshers,” which can be great — more shares! But over time, the accumulation of all that company stock also can become a much bigger chunk of your portfolio than you intended. When you consider that the value of your vested shares, unvested shares and your salary are coming from the same place, it’s easy to see how your finances might become dependent on the success or failure of one company. If it hits a rough patch, your income and your investments may take a hit together. A financial advisor can help you work out how much company stock makes sense for your situation and goals, whether and when to sell some of your equity, and how to strategically diversify your portfolio.

10b5-1 plans

If you’re an executive, director or employee with access to material nonpublic information, your status as an insider may affect your ability to sell shares. A Rule 10b5-1 plan allows insiders to trade company stock on a set schedule. The terms of the trades (such as number of shares, price and trade dates) are set ahead of time, often via a formula, algorithm or other calculation.

Private versus public company equity

If you work for a private company, selling your shares can be hard. You may have to wait until your company goes public, is acquired or makes a tender offer (which is when the company or an investor offers to buy shares from employees). You may also have to bring more cash — private companies can be less likely to offer sell-to-cover programs, which allow you to sell shares to pay for things like taxes or the strike price of options. And even if an IPO is on the horizon, there may be a lockup period that will prevent you from selling your shares right away.

With RSUs, private companies may require both time and a liquidity event (such as an IPO or acquisition) before they vest, but at least that means you aren’t taxed on shares you can’t sell.

Knowing when to sell

Whether and when to sell your equity depends on a variety of factors, including your near-term cash needs, the tax costs, the equity compensation as a percentage of your net worth and your outlook for the company.

It’s also hard to keep the emotions out of the decision when it comes to your company’s stock. For example, many people struggle with these factors:

Feeling that it’s disloyal to sell the company stock. Ask: If this were a cash bonus, would you use all of that cash to buy your company’s stock? If the answer is no, consider selling.
Fear of regrets if the share price goes higher after the sale. This is classic FOMO.
Holding the shares solely to get long-term capital gains tax treatment. A sale soon after vesting often produces little gain, and thus little tax obligation. If you’re torn, a financial advisor can help you weigh the tax costs against your goals.
Relying on rumors of an IPO. Companies sometimes dangle IPO messaging as a way to retain employees. It takes more than wishful thinking to make an IPO happen.

Talking with a qualified financial advisor can help bring other perspectives into view and help you consider all the sides of a decision to sell.

Weighing a job offer: How to think about equity compensation in relation to other pay

A salary is a known quantity, paid on a schedule in return for time and expertise. A bonus is often cash tied to results. But equity compensation is a bet on the company’s future. So one way to think about equity compensation is as a potential upside on top of cash you can count on, rather than a substitute for that cash. Here’s how the pieces differ, plus some questions to ask before you say yes.

Equity compensation versus other types of compensation

Compensation type	Pros	Cons
Regular wages	Earned and paid relatively immediately. You generally know how much it’s worth in advance. Typically doesn’t go down if the company’s stock price dips.	Typically doesn’t automatically go up if the company is doing well. Is usually taxable once you get it.
Cash bonus	Is in cash. Often is tied to personal or team achievements.	Typically is infrequent. Is usually taxable once you get it.
Equity compensation	Depending on terms, can generate significant wealth if the company does well. Some types (like ISOs) can be a way to defer taxes until you sell.	May be worthless if the company doesn’t do well (or well enough). Some situations can generate a tax bill even if you haven’t sold the shares or received any cash.

Questions to ask if equity comp is in your offer letter

How many shares are in the award?
What is the strike price?
When did the company last obtain a valuation, and what was the value per share?
How many shares are outstanding now?
What events must occur in order for the options or shares to vest?
Over what time period do the shares or options vest?
When does the grant expire?
Is early exercise allowed?
What happens if the company is acquired or I am terminated or laid off?
