The 10 Types Of Equity Compensation, Explained
10 Types of Equity Compensation, Explained
From ISOs and RSUs to phantom stock and profits interests: how each type works, how it's taxed, and what it means for your financial plan.
Equity compensation comes in 10 main forms: incentive stock options (ISOs), non-qualified stock options (NQOs), restricted stock units (RSUs), performance shares, employee stock purchase plans (ESPPs), stock appreciation rights (SARs), phantom stock, restricted stock awards (RSAs), direct stock ownership, and profits interests in LLCs. Each type is taxed differently and carries its own vesting rules, so the right strategy depends on which one, or combination, is sitting in your equity award agreement. For tech professionals, equity compensation is often the single largest lever in a financial plan: bigger than salary, bigger than a 401(k) match. Knowing which type you hold is the first step to deciding when to exercise, when to sell, and how to plan around the tax bill.
What Is an Incentive Stock Option (ISO)?
An Incentive Stock Option (ISO) is a right to buy company shares at a fixed exercise price, granted only to employees, not contractors or board members. The exercise price equals the fair market value of the stock on the grant date, and ISOs are typically issued early in a company's life, when the stock price, and the potential upside, is low.
To get favorable tax treatment, you generally need to hold ISO shares for at least two years from the grant date and one year from the exercise date. Meet both holding periods, and your gain on sale is typically taxed at long-term capital gains rates instead of ordinary income rates. Exercising ISOs doesn't trigger regular income tax, but it often triggers the Alternative Minimum Tax (AMT), a separate tax calculation that can catch employees off guard if they're not planning for it.
Exercising a large ISO grant in one calendar year can push you into AMT territory even though you haven't sold a single share. Modeling the exercise before you do it is the difference between a planned tax bill and a surprise one.

A Non-Qualified Stock Option (NQO) is a right to buy company stock at a fixed price that can be granted to employees, consultants, and other stakeholders, not just employees, which is where it differs from an ISO. This flexibility makes NQOs a common choice for companies that want to incentivize a broader group of contributors beyond the W-2 workforce.
NQOs and ISOs are similar in structure but taxed differently. When you exercise an NQO, the spread between the exercise price and the fair market value on the exercise date is taxed as ordinary income immediately, which is why many employees exercise and sell NQOs on the same day, often called a cashless exercise. Because exercising is optional, an NQO only has value if the company's stock price rises above your exercise price.
Type 3What Is a Restricted Stock Unit (RSU)?
A Restricted Stock Unit (RSU) is a company's promise to deliver shares, or cash of equal value, once a vesting requirement is met, with no purchase required. Unlike ISOs, NQOs, or ESPPs, RSUs don't ask you to buy shares at a discount or decide when to exercise; you simply receive the shares once vesting requirements, whether time-based or performance-based, are satisfied.
RSUs are taxed as ordinary income at vesting, based on the fair market value of the shares on that date, then any further gain or loss when you sell is taxed as a capital gain or loss. Because vesting requirements typically span several years, RSUs are also a common tool for retention: leave the company before the vesting date, and you generally forfeit the unvested units.
What Are Performance Shares?
Performance shares are company shares awarded through an equity plan where vesting depends on hitting specific performance targets, not just time served: think revenue milestones, stock price benchmarks, or individual KPIs, on top of a standard vesting schedule. Employers use performance shares to tie compensation directly to company results, which is why they're common in senior and executive-level equity packages.
Performance shares carry more upside than a standard RSU grant if targets are exceeded, but more downside too. Miss the targets, and you may vest into fewer shares than expected, or none. That asymmetry makes performance shares one of the equity types most worth reviewing with an advisor before you count on their value in a financial plan.
Type 5What Is an Employee Stock Purchase Plan (ESPP)?
An Employee Stock Purchase Plan (ESPP) lets employees buy company stock at a discount, typically 5% to 15% off, through after-tax payroll deductions accumulated over an offering period. At the end of the period, those contributions are used to purchase shares, often at the lower of the stock price at the start or end of the period.
Qualified ESPPs, structured under IRC Section 423, offer the most favorable tax treatment if shares are held long enough to qualify for a "qualifying disposition." Non-qualified ESPPs skip the special holding period rules but also skip the tax benefits. Either way, the mechanics stay simple: decide a contribution percentage, let payroll handle the rest, and receive discounted shares at the end of each offering period.
Type 6What Are Stock Appreciation Rights (SARs)?
Stock Appreciation Rights (SARs) pay employees the increase in a company's stock price over a set period, in cash or shares, without requiring them to buy or hold any actual stock. If the stock price rises, the holder receives the difference between the value at grant and the value at the end of the period; if it doesn't rise, the SARs simply expire worthless, with no money at risk.
For example: an employee granted 1,000 SARs at $50 per share, vesting when the stock reaches $75 per share, would receive a $25,000 payout, the $25 per-share gain multiplied by 1,000 SARs. SARs let employees participate in stock price growth while avoiding the exercise cost and ownership risk that come with traditional stock options.
Type 7What Is Phantom Stock?
Phantom stock is a deferred compensation arrangement that pays a future cash bonus equal to the increase in value of a set number of company shares, without ever issuing actual shares. Companies use phantom stock to reward employees for stock price growth without diluting ownership, which is why it's most common in upper-management compensation packages.
A phantom stock plan typically specifies a vesting schedule, a grant date, and defined payout triggers: retirement, a change in control, or a fixed date are common examples. Because no real equity changes hands, phantom stock is taxed as ordinary income when the cash payout is received, similar to a bonus.
Type 8What Is a Restricted Stock Award (RSA)?
A Restricted Stock Award (RSA) grants actual company shares on the grant date, making the recipient a shareholder immediately, subject to a vesting schedule that determines when full ownership rights apply. Vesting is typically tied to tenure or performance milestones and often spans several years.
Because RSA recipients are shareholders from day one, the fair market value of the shares is taxable at grant, unless the recipient files a Section 83(b) election or the agreement defers taxation until vesting. This is a meaningfully different tax trigger than an RSU, where taxation always happens at vesting: the timing distinction is one of the most common points of confusion between the two.
Type 9What Is Direct Stock Ownership?
Direct stock ownership is exactly what it sounds like: an employee holds company shares outright, either through a bonus grant or a direct purchase, with no vesting schedule or conditional structure attached. It's the most straightforward form of equity compensation on this list, and it puts the employee's financial outcome directly in line with the company's performance.
Some direct stock ownership arrangements allow elective deferral contributions, where employees defer a portion of salary into stock ownership, a strategy that can carry favorable tax treatment for employees in higher income brackets when structured correctly.
Type 10What Are Profits Interests in LLCs?
A profits interest is an equity award granted to employees of a limited liability company (LLC) that represents a share of future appreciation in the company's value, not a stake in the LLC's current value. This distinction separates a profits interest from a capital interest, which does represent a claim on existing company value.
Profits interests are typically structured to be tax-efficient at grant, since the recipient isn't taxed on value they don't yet have a claim to, only on future growth as the LLC's value increases. That structure is one reason profits interests are a common equity tool at LLCs looking to reward key employees without triggering an immediate tax bill.
