Put Equity Compensation in Context
An 91做厙 Engines advisor can help you clarify options and make strategic timing decisions.
Equity compensation is non-cash pay offered by employers in the form of company stock, such as restricted stock units, stock options or employee stock purchase plans. It can help employees build wealth but also comes with tax implications and investment risks that should be carefully managed.
When it comes to your job, you know what compensation is it's reflected in the paychecks you get every couple of weeks. But you might be surprised the first time an employer offers you equity compensation, which wont appear in your regular direct deposits. In addition to your regular pay, theyre offering to compensate you in the form of an ownership stake in the company.
Employee equity compensation can have the potential for a lot more value than your regular paychecks, but it also comes with choices and complexity. Understanding what youve been granted and what decisions youll eventually have to make is what turns equity compensation from a confusing perk into something you can actually plan around.

WHAT IS EQUITY COMPENSATION?
Equity compensation is a way for companies to pay employees not just with cash, but with ownership in the company. Instead of (or in addition to) salary or bonuses, youre given stock-based benefits that can become more valuable if the company grows. The upside is obvious: If the company does well, you may be able to share in that success. The tradeoff is complexity, especially around timing, taxes and risk.
Companies offer an equity compensation plan to attract and retain employees and to give them incentives toward long-term company success. Its most commonly offered to executives, senior leaders, and high-impact employees whose work significantly influences company value, and its common in startups, tech and other growth industries.
There are several different kinds of equity compensation. Well take a look at that next.

TYPES OF EQUITY COMPENSATION
RESTRICTED STOCK UNITS
With a restricted stock unit, your employer grants you a certain amount of stock. The RSUs are restricted because you dont own them right away. Instead, there are requirements to be met, most often a vesting schedule. As you meet the requirements, the stock becomes yours.
For example, an employer might grant you 100 shares on a 5-year vesting schedule. After one year, you might own 20 shares. After two years, youd own 40 shares, and so on.
As the stock vests, its value on the vesting date is usually taxed as ordinary income, even if you dont sell it.
STOCK OPTIONS: ISO VS. NSO
Stock options give you the opportunity to buy company stock in the future at a fixed price, called the grant or strike price. If the company stock rises above that price, you can buy low and potentially sell high. If it never rises, you dont have to do anything at all. Options usually expire after a set amount of time, so theyre eventually worthless if you never exercise them (meaning, buy the stock).
There are two main kinds of employee compensation stock options. Nonqualified stock options create taxable income when you exercise them, even if you hold onto the stock and dont sell your shares. Incentive stock options can receive more favorable tax treatment, but only if you follow strict holding rules after exercising them.
EMPLOYEE STOCK PURCHASE PLANS
Some employees also have access to employee stock purchase plans, which allow you to buy company stock through payroll deductions, often at a discount. ESPPs can have the same kind of favorable tax treatment as ISOs if all requirements are met.

HOW EQUITY COMPENSATION IS TAXED
Different kinds of equity compensation are taxed differently, and its important you understand the consequences before they hit your wallet.
RSU TAX TREATMENT
RSUs are typically taxed like ordinary income when they vest. So, if you have stock worth $50,000 vesting, its like getting a $50,000 cash bonus.
Note that you dont have to sell the stock to owe taxes on it. So, if you want to hold onto it, youll need cash to cover the tax bill.
Of course, employees of private companies dont usually have the option of selling, which could leave them in a quandary. However, most private company employees have the option of making a Section 83(i) election with the IRS, which allows them to defer the income for up to five years. That can help if youre waiting for an IPO or other company sale to go through.
NSO TAX TREATMENT
With NSOs, the income thats taxed is usually the difference between the strike price and the current market price when you exercise the options in other words, the value of the discount gets taxed. So, if you exercise options that allow you to buy 1,000 shares of stock at $50, and the market price is $75, youll be taxed on $25,000 ($25 discount x 1,000 shares). As with RSUs, this is true even if you hold onto the stock, so youll need cash to cover the bill, unless you qualify for and make a Section 83(i) election.
If your company isnt publicly traded, theres no market price you can refer to. In that case, the value of the stock (and therefore the income youre taxed on) is what the company determines to be its fair market value, often from an annual 409A valuation.
ISOS TAX TREATMENT
With ISOs, you usually wont owe taxes until you sell the stock (with one important caveat, which well get to). Instead, assuming you meet the requirements, the money you make from the exercise is taxed as long-term capital gains when you sell shares.
For example, say you exercised your right to buy 1,000 shares of stock at $50 as part of an ISO instead of an NSO. The stocks market price at exercise is once again $75, but you dont owe income tax. You hold onto the stock for another year until its worth $85 and then sell. Your gain of $35,000 ($85 sale price - $50 cost basis x 1,000 shares) is taxed as long-term capital gains, which has lower rates than ordinary income.
To get this best-case tax scenario, you need to make sure your sale of stock is a qualifying disposition, which among other things, means:
- Its been at least two years since the options were granted, and
- Its been at least one year since the options were exercised
If you dont meet the requirements, the ISOs will be taxed more like NSOs when you sell, with the discount ($25 in our example) taxed like ordinary income and any post-exercise gains ($10 in our example) taxed as capital gains.
Now, to the caveat: You might owe taxes at exercise of an ISO if you fall under the alternative minimum tax system, which generally applies to people who have a lot of income and a lot of deductions. When calculating AMT, the value of ISOs (the discount) is a preferential item that counts as income.

BENEFITS OF EQUITY COMPENSATION
Equity compensation can be high-risk, high-reward. Theres always the possibility that options will never be exercised, or that stock values will fall instead of rise, eroding your compensation.
But the flip side is also true: Stock values could soar if your company goes through a period of intense growth, an IPO or other sale. Receiving equity compensation can give you a sense of ownership, pride and dedication that makes your job more meaningful and engaging.

RISKS TO CONSIDER BEFORE YOU RELY ON EQUITY COMPENSATION
Weve already mentioned some of the risks of equity compensation: If your companys stock value drops (whether its because of company performance or a market downturn), your stock or stock options could be worth much less than you expected or even nothing at all.
This is especially risky if you dont have a cash cushion to get you through hard times. You could be forced to sell when stock prices are down or, in the case of ISOs, before a sale would qualify for preferential tax treatment.
Stock and stock options can also open you up to the risk that bad company performance will hurt your financial security. A large part of your financial stability your job and income is already tied to your company. Having a lot of your portfolio in stock and stock options for the same company compounds that risk.
泭
WHEN SHOULD YOU EXERCISE OR SELL YOUR EQUITY COMPENSATION?
Deciding when to exercise or sell equity compensation is often less about finding the perfect moment and more about weighing a few considerations.
One is diversification: As company stock grows into a larger share of your net worth, selling some shares can help reduce concentration risk.
Another is taxes, since the timing of an execution or sale can influence whether gains are taxed as ordinary income or capital gains, and whether executing or selling in a particular year pushes your total income into a higher tax bracket.
Your current cashflow needs also matter you may need money to fund nearterm goals like buying a home, paying college costs, or paying taxes due on RSUs or an options exercise.
Finally, practical constraints can play a role, such as:
- Vesting schedules, since you cant sell any stock until it vests
- Expiration dates for options
- Trading windows or limitations set by your employer
- The stocks price you wouldnt want to execute an option if its trading below the strike price
STRATEGIES TO HELP MANAGE EQUITY COMPENSATION
One of the biggest risks with equity compensation isnt obvious at first. Over time, company stock can quietly grow into one of your largest assets while your income is also tied to the same employer. That combination can leave you overly exposed to the fortunes of a single company.
Diversification doesnt necessarily mean selling everything right away, but it does mean being intentional about how much of your net worth youre willing to have tied to one stock and recognizing when equity compensation is shifting from a growth opportunity into a concentration risk. Managing that balance often involves timing sales, spreading them over multiple years, or coordinating equity decisions with other savings and investments.
When youre thinking about exercising options or selling stock, thoughtful tax planning can also help you avoid surprises and make tradeoffs consciously rather than reactively.
Of course, the best tax planning is done in concert with your overall financial planning. Taxes can be an important consideration, but decisions also have to work for your situation and goals. A financial advisor can help you connect the dots strategically and take the best advantage of your opportunities.
