Today, stock options are part and parcel of employee compensation as a way to attract and retain quality talent within a competitive job market. From a corporate perspective, stock options are a way for employees to get in on the gains of a growing organization.
This article explores how stock options work, who gets them, tax implications, the pros and cons of this options and FAQS about stocks for HR professionals and career counselors.
Stock options also known as equity options are a form of equity compensation where companies allow employees to purchase stock at a predetermined strike price over a period of time.
The strike price is the value at the time of granting; usually the market price at the time of granting. Therefore, if employees hold onto their equity options for a set time and the company stock goes up, they're able to buy stock at a lower price and sell when they're able to exercise equity options.
Equity options are intended to incentivize people to work harder for the benefit of the company.
These are most common in tech and startup companies but are also common in companies that have been around for awhile. They are not common within unionized settings (where all compensation is open and spelled out).
Employees do not receive stock; they receive the option to purchase stock.
Organizations must ensure that equity compensation complements competitive base salary structures rather than replacing them entirely. Solutions like Compensation Software help HR leaders benchmark total compensation packages (including salary and equity incentives) against market data to ensure offers remain competitive.
Companies use equity options as a way to attract and retain talent because it minimizes upfront cash outlay. They allow employees to earn their keep and develop wealth over time. They also incentivize employee performance tied to shareholder performance.
With a more competitive environment, companies must try to offer more money than other competing companies.
| Reason | Benefit to Company | Benefit to Employee |
|---|---|---|
| Talent Attraction | Low upfront cost | Potential for gains |
| Retention | Vesting periods encourage loyalty | Wealth building opportunity |
| Performance Drive | Ties pay to stock value | Shares in success |
A survey found that almost 50% of employees say equity compensation such as equity options are one of the greatest benefits when they're looking for a new job, showcasing how benefits have changed over time.
To effectively administer these long-term incentives, organizations rely on structured reward management solutions such as Compensation Planning, which enables companies to manage equity awards alongside salary increases, bonuses, and total rewards budgets.
Employees get equity options in the form of a grant that includes how many equity options they will receive, the strike price (predetermined) and the vesting schedule.
Usually, equity options vest in four years with a one year cliff where nothing can be exercised. The employee exercises their stock options by paying the predetermined price for their shares.
A ten-year exercise period is typical.
Equity options are either in the money (if the strike price is lower than the existing market value) or they are worthless (current market values are less than the strike price). Either way, if they don't buy them, they expire worthless.
Once equity options are exercised, the employee can choose to sell them immediately, or hold onto them.
Employees receive the option (not the obligation) to buy stock at a predetermined strike price. This includes voting rights once the shares are exercised and if dividends are declared, employees will receive those dividends according to what is held.
However, until an employee exercises their option, there is no value and no shareholder rights.
Rights to purchase stock at a reduced price (if exercised).
Capital gains potential upon sale of stocks that are now valued higher than the strike price.
There is no downside risk to the employee other than failing to exercise equity options.
Employers will typically offer two types of equity options: incentive equity options or non-qualified equity options. Each appeals to certain employees at certain times and comes with different eligibility requirements, tax treatment and pros and cons for each.
| Type | Eligibility | Key Feature |
|---|---|---|
| ISO | Employees only | Tax advantages |
| NSO | Employees, consultants | More flexible |
ISOs are granted for preferential tax treatment. Employees may buy stock at a predetermined strike price and if they hold (two years from granting, one year from exercising), they may get capital gains instead.
Incentive equity options are limited to $100,000 of vesting per year.
Employees do not pay taxes upon exercise of their incentive equity options, but depending upon their other financial investments, they may pay alternative minimum tax.
Incentive equity options are great for long-term holders.
The National Bureau of Economic Research found that while incentive equity options incentivize specific employees, risk-averse employees believe it's unfortunate for them since it decreases their compensation further down the line.
NSOs are available for anyone rendering services to a company; employees and board members included. They do not enjoy the tax benefits of ISOs, however, they're a more straightforward form of equity compensation.
The employee will owe ordinary income tax to the extent of the gain from the difference between exercise price and market value at the time of exercise.
There is no requirement for an employee to hold on to shares once exercised.
Employers get a tax deduction at exercise.
Non-qualified equity options allow for widespread incentive compensation across multiple types of workers.
Equity options are taxed at the time of exercising or sale. Incentive equity options are not taxed upon sale unless regulations are stipulated; non-qualified equity options are taxed at exercise based on the straight spread calculation.
Once a sale occurs (after exercising), capital gains taxation occurs based on how long stock is held during appreciation and prior to sale price.
Employees must understand the potential tax burden from exercising large life events.
The best option is to consult with a tax professional to minimize tax burdens.
The major events that trigger taxes are when the employer exercises and when a sale occurs. At exercise, all non-qualified equity options will add to ordinary income and be taxed as grossed up events; with incentive options this may trigger AMT instead. When sold, there will be capital gains taxes.
| Event | ISO Tax | NSO Tax |
|---|---|---|
| Grant | None | None |
| Exercise | Possible AMT | Ordinary income on spread |
| Sale | Capital gains if qualified | Capital gains on post-exercise gain |
Stock options can become worthless if market prices crash; they become underwater when strike prices are higher than market prices. In addition, illiquidity occurs in private companies which makes them unpredictable either way.
Volatility can wipe options out in an instant.
Employees can be overconcentrated to their company stock; while companies want employees to hold onto company stock, it's too risky without diversification.
Options expire when an employee no longer works for the company; this advantage is not portable.
A poorly designed option fails to align expectations properly and if vesting periods are too long or too short, retention is low; immediate no-value options or strike prices higher than market prices lead to inequity.
In addition, poorly implemented equity options ultimately show owners assumed too much cash need.
If vesting against employee goals occurs, they may leave without receiving anything significant.
If taxes go against employee preference then net numbers won't come out right, especially if they think they're getting more.
It's about communication; poor communication leads poorly valued tokens and not realized holdings.
To improve transparency and employee understanding, organizations use Total Compensation Statement, which presents salary, bonuses, benefits, and equity compensation, including equity options, in a clear total rewards view.
Here are the common questions about the topic:
They build wealth over time, especially in growing firms. Employees should view them as part of diversified savings, exercising wisely to capture gains.
Assess vesting, strike price, and company prospects. Compare to salary; calculate potential value using projections. Factor in taxes and risks.
At startups, high growth potential but higher risk; large companies offer stability with lower upside. Startups often grant more options to compensate.
They add variable income, requiring budgeting for exercise costs and taxes. Integrate into retirement plans; diversify to mitigate risks.
