Equity Compensation: Stock Options and Restricted Stock for Private Companies

Equity compensation — giving employees or service providers an ownership interest in the company, or the right to acquire one — is one of the most valuable tools available to private companies for attracting and retaining talent. For employees who receive it, equity can represent a transformative financial opportunity. For companies that grant it, equity compensation aligns employee incentives with long-term company success and allows early-stage businesses to compete for talent against larger, cash-richer employers. But equity compensation is also one of the most legally and tax-complex areas of employment and corporate law, and mistakes in structuring or administering equity programs can create serious consequences for both companies and recipients.

Incentive Stock Options (ISOs)

Incentive stock options are a form of stock option that, when properly structured and exercised, can provide employees with the most favorable tax treatment available for equity compensation. ISOs can only be granted to employees (not consultants or outside directors), must be granted under a written plan approved by shareholders, must have an exercise price at least equal to the fair market value of the stock on the grant date, and are subject to a $100,000 annual limit on the value of options that can first become exercisable in any calendar year.

The tax treatment of ISOs is distinctive: there is no ordinary income tax upon grant or exercise of the ISO (though the spread at exercise may be subject to alternative minimum tax). If the stock is held for at least one year after exercise and two years after the grant date, the gain upon sale is taxed as long-term capital gain rather than ordinary income. This can result in tax rates significantly lower than those applicable to other forms of compensation. If the holding periods are not met (a ‘disqualifying disposition’), the spread at exercise is treated as ordinary income.

Non-Qualified Stock Options (NSOs)

Non-qualified stock options can be granted to employees, consultants, advisors, and directors. They do not have the $100,000 annual limit that applies to ISOs and are not restricted to employees. The tax treatment is less favorable: upon exercise, the spread (the difference between the fair market value on the exercise date and the exercise price) is treated as ordinary income and is subject to income and payroll taxes. For employees, the company is required to withhold taxes at exercise. The company receives a corresponding deduction equal to the ordinary income recognized by the option holder at exercise.

Restricted Stock and Section 83(b) Elections

Restricted stock is an actual grant of shares to an employee or service provider, typically subject to a vesting schedule under which the company retains the right to repurchase unvested shares if the employee leaves before vesting. By default, the tax rules treat restricted stock as compensatory income at the time restrictions lapse (i.e., as each tranche vests), with the income equal to the fair market value of the shares at the time of vesting minus any amount paid by the employee for the shares.

The Section 83(b) election allows the recipient of restricted stock to elect to recognize ordinary income based on the fair market value at grant rather than at vesting, paying tax early when the value may be low (particularly important for early-stage startups where the stock may be worth very little at grant but substantially more by the time it vests). If the company is successful and the stock appreciates significantly, subsequent appreciation is taxed as capital gain rather than ordinary income. A Section 83(b) election must be filed with the IRS within 30 days of the grant date — this deadline is absolute, and there are no exceptions.

Restricted Stock Units (RSUs)

RSUs are promises to deliver shares (or cash equivalent to the value of shares) to an employee upon the satisfaction of specified conditions, typically a vesting schedule and often a liquidity event (an IPO or acquisition). Unlike restricted stock, RSUs do not constitute actual ownership of shares before vesting, so there is no ability to file a Section 83(b) election. RSUs are taxed as ordinary income when they vest (or, for RSUs that vest upon a liquidity event, at that event). RSUs are common at later-stage private companies and at public companies, where the tax treatment at vesting is less problematic because there are liquid shares available to sell to cover the tax liability.

Setting the Exercise Price: 409A Valuations

For private companies, setting the fair market value of stock for purposes of option exercise prices is governed by Section 409A of the Internal Revenue Code, which requires that options have an exercise price at least equal to the fair market value of the underlying stock on the date of grant. Setting too low an exercise price can result in the option being treated as deferred compensation subject to punitive tax treatment. To comply with Section 409A and to have a defensible basis for the exercise price, most private companies obtain an independent 409A appraisal before each grant or grant cycle. These appraisals are conducted by qualified independent valuation firms and are typically valid for up to 12 months.

Securities Law Considerations

Stock options and restricted stock grants to employees are generally exempt from SEC registration under Rule 701 if the company meets the requirements of that exemption, which include limits on the total amount of securities that can be offered under compensatory arrangements in a 12-month period relative to the company’s total outstanding securities. Companies that exceed Rule 701 thresholds must provide employees with additional financial disclosures. State securities laws may impose additional requirements.

The Bottom Line

Equity compensation is a powerful tool with substantial legal, tax, and securities law complexity. Companies that design equity programs without careful legal and tax advice frequently create problems — grant options at incorrect exercise prices, fail to obtain 409A appraisals, miss Section 83(b) election deadlines for restricted stock grants, or inadvertently violate Rule 701. Employees who receive equity without understanding its tax treatment are frequently surprised by large tax bills at exercise or vesting. The value of equity compensation is maximized when both company and recipient understand exactly what they have and how it works.
