TLDR: Startup equity compensation is how a company gives a piece of its ownership pie to employees, directors, advisors and consultants. Typically, these stock option awards work differently from the founder stock issued at formation. Key considerations when issuing equity compensation are how big you should make the company’s option pool, whether the company should grant incentive stock options under IRC Section 422 or nonqualified stock options, setting the exercise price per share through an IRC Section 409A valuation, and whether to provide equity compensation with the ability to early exercise paired with an IRC Section 83(b) election. Undoing and cleaning up poorly issued startup equity compensation can be messy and expensive, so engaging the right legal counsel from day one is critical.
What is startup equity compensation, and how is it different from founder stock?
Startup equity compensation is the right to own a piece of your company that you grant to employees, directors, advisors, and consultants as compensation for their services. It is a different legal instrument from the founder stock issued at formation.
Founders typically receive shares of restricted stock at formation for a nominal price and file an 83(b) election. As the company grows and adds team members, it often compensates them with stock options, which are a contractual right to buy a fixed number of shares at a later date at a price set today, granted under an equity incentive plan. Stock options can be issued as incentive stock options (ISOs) or nonqualified stock options (NSOs), and depend on the individual’s role with the company receiving the equity compensation. Treating founder stock and stock options as the same thing is a common mistake and can create tax and securities law problems for your company.
How big should your option pool be, and who does it dilute?
The option pool is a reserve of shares set aside for the company to grant stock options to its team. The right size depends on several factors and should be considered on a case-by-case basis. If the pool is too large, then founders often absorb the extra dilution.
Typically, pre-seed and seed-stage companies adopt option pools equal to ten, fifteen, or twenty percent of the company’s fully diluted capitalization. The option pool should be large enough to cover the company’s intended hires until it raises its next funding round. In a priced-equity round, investors will likely require the company to increase its option pool for future hiring.
When investors require you to create or expand the pool as a condition of a priced round, that pool is almost always carved out of the pre-money valuation (i.e., the existing stockholders and founders absorb the dilution, not the incoming investors). By setting an option pool at formation or soon after, founders maintain more control and leverage in future negotiations.
ISOs or NSOs: which option type fits which person?
Incentive stock options (ISOs) can only be issued to W-2 employees and can qualify for better tax treatment. Nonqualified options can be issued to any team member, but are taxed as ordinary income on the spread at the time of exercise.
There are two types of stock options that a company can issue, ISOs and NSOs, and their main difference is how they are taxed. Incentive stock options (ISOs), under IRC Section 422, can only be issued to W-2 employees and can qualify for favorable treatment (i.e., no regular income tax at exercise and the chance of long-term capital gain on sale if the holding periods are met, though the spread at the time of exercise is an item for the alternative minimum tax). Nonqualified options (NSOs) can be issued to any type of team member, including directors, advisors, consultants, etc., but the difference between the exercise price and the fair market value at the time of exercise is taxed as ordinary income.
ISOs have two main limitations. First, only employees can hold ISOs. Also, ISOs carry a $100,000 limit under IRC Section 422(d). To the extent the value of stock for which ISOs first become exercisable in a year exceeds $100,000, measured at grant, the excess is treated as NSOs. Also keep the holding rules under IRC Section 422 in mind, which require holding the shares for more than two years from the grant date and more than one year from the exercise date. From a tax perspective, the general rule is to issue ISOs for employees, NSOs for everyone else, and structure the company’s equity plan to allow both.
Why does a 409A valuation matter before you grant an option?
A 409A valuation serves as an independent appraisal of the value of your company’s common stock. Stock option grants must be priced at or above fair market value. If a stock option grant is priced below fair market value, the tax penalty falls on the grantee, and the company may face a due diligence issue.
IRC Section 409A requires that stock options be granted at an exercise price at or above fair market value. If stock options are priced too low, the option can be treated as deferred compensation that violates IRC Section 409A, triggering immediate income tax on vesting plus an extra 20% federal penalty for the option holder. That penalty falls on your team member, not the company, which makes this a retention issue, not just a compliance one.
To avoid this outcome and for future due diligence, founders often pay for a formal valuation under IRC Section 409A. A valuation by a qualified independent appraiser is presumed reasonable, and the IRS has the burden to prove otherwise, giving the company a safe harbor to rely on. Without it, the company has to defend its own price to the IRS if challenged. Typically, obtaining a 409A valuation is straightforward, so companies obtain it before granting options, refresh it at least every twelve months, and refresh it sooner after any material event such as a priced-equity round. Granting options without a current 409A valuation is one of the most common due diligence questions.
What is early exercise, and when should it be used?
An early-exercise stock option allows a grantee to exercise the stock option and buy the underlying shares before they vest. Paired with a timely 83(b) election, it can start the capital gains clock early, but it means putting cash at risk on unvested, illiquid stock.
The early exercise feature lets a grantee exercise some or all of the option shares before they vest, buying restricted stock that the company can repurchase on the original vesting schedule. Early exercise structures an option similar to restricted stock. The appeal for grantees is tax timing. If a grantee early exercises the stock option while the spread is close to zero and files an IRC Section 83(b) election within the 30-day deadline, the grantee can start the capital gains and qualified small business stock (QSBS) clocks right away. When the stock is still cheap, an early exercise can turn what would have been ordinary income into long-term capital gains and significant tax savings if the QSBS conditions are met. Also, most early-exercise stock options are granted as NSOs for additional tax efficiency.
Early exercise means paying for stock that has not vested, so if the grantee leaves early, the company can (and usually does) buy back the unvested shares. The 83(b) election must be filed before the 30-day deadline, and missing it wipes out the benefit. Early exercise is powerful for team members at a company whose stock is still near its formation value, but it primarily benefits the grantee, not the company. Early exercise should be the exception, and not the norm when issuing stock option grants.
For additional details, the CCG founder vesting guide covers the 83(b) mechanics in more depth, since the same election governs founder stock.
Should an early-stage startup ever use RSUs?
Usually not. RSUs are taxed when shares are delivered, and a private company gives the recipient no way to sell shares to cover the tax burden.
Restricted stock units (RSUs) are a promise to deliver shares later, and for an early startup they are usually the wrong tool given their tax treatment. RSUs are generally taxed as ordinary income when they settle and the shares arrive, and a private company has no public market where the recipient can sell shares to pay that tax bill. That is why private companies that use RSUs usually add a liquidity-event condition, so shares settle only when there is a way to pay the tax, meaning the RSU delivers nothing until an exit.
You might consider RSUs once the value of your company’s common stock has increased to the point that the cost of exercising options makes it difficult to hire new employees, or when a liquidity event is close. At the seed or Series A stage, stock options and restricted stock often work better for founders and team members. Using RSUs early sometimes indicates that the equity plan was copied from a later-stage template instead of rightsized for where your company is today.
What securities rules apply when you hand out equity?
Every equity grant is the sale of securities and therefore must comply with the applicable federal and state securities laws. Federally, Rule 701 covers compensatory grants. At a state level, California Corporations Code Section 25102(o) covers the plan in California, and blue sky filings may be required depending on where the company and grantees are located.
Every grant of equity is an offer and sale of securities, so it has to comply with state and federal securities laws. Federally, the common exemption from registration for compensatory equity is Rule 701 under the Securities Act of 1933, as amended, which exempts compensatory grants to employees, directors, and certain consultants of a private company, subject to annual dollar limits and, once you cross a threshold of securities sold in a twelve-month period, added disclosure requirements. If you grant a lot of equity in a year, work with your counsel to confirm that you stay inside Rule 701 and provide the extra disclosures when the threshold trips.
In California, compensatory plans are handled by Cal. Corp. Code Section 25102(o), which exempts options and other equity issued under a plan that complies with Rule 701, subject to a filing and applicable filing fee. This exemption is what early-stage California companies most often rely on for their equity plans, and it is separate from the Cal. Corp. Code Section 25102(f) exemption used for financings. The equity plan, the grants, and the exemption filings are one connected system. Adopting a compliant plan, granting under it, and keeping the filings current is ordinary housekeeping, but if you leave it undone, it can become a diligence problem in the middle of your next financing round and can result in hefty penalty fees. If the grantee is in another state or the company is headquartered in another state, the company will also need to qualify under that state’s securities laws.
Frequently Asked Questions
What are key differences between ISOs and NSOs?
Incentive stock options under IRC Section 422 can only be issued to W-2 employees. They can qualify for favorable tax treatment, with no regular income tax at exercise and possible long-term capital gains and QSBS treatment if the holding periods and other conditions are met. However, the spread is an AMT item. Nonqualified options can be issued to anyone, but remember that the spread at exercise is taxed as ordinary income. ISOs also carry a $100,000 annual limit under IRC Section 422(d), above which they are treated as NSOs.
How big should a startup’s option pool be?
Pre-seed and seed-stage pools often range from 10% to 20% of a company’s fully diluted equity capitalization, but the right size depends on a company’s future hiring needs, not a rule of thumb. Because investors usually carve a new or expanded pool out of the pre-money valuation, an oversized pool is founder dilution given away for no hire, so build the plan first and defend the number.
What is a 409A valuation and do I need one?
A 409A valuation is an independent appraisal of the current fair market value of your company’s common stock. IRC Section 409A requires that options be granted with an exercise price that is at or above its then fair market value. A valuation by a qualified independent appraiser creates a safe harbor that presumes the price is reasonable. You need one before granting options, refreshed at least every twelve months and after any material event, because a mispriced option can trigger immediate tax plus a 20% penalty for the holder.
What is the early exercise of a stock option?
An early-exercise stock option allows the holder to exercise and purchase the underlying shares before they vest. The stock option effectively converts into shares of restricted stock, which the company can repurchase on the original vesting schedule. If the IRC Section 83(b) election is filed within the 30-day deadline, the early exercise can start the capital gains and QSBS clocks early, turning future appreciation into long-term capital gains and additional tax savings. Early exercise works better for early employees while the stock is cheap, but it carries the risk of paying cash for unvested, illiquid shares.
Do RSUs make sense for an early-stage startup?
Usually not, because RSUs are generally taxed as ordinary income when the shares are delivered, and with a private company, there usually is no market in which to sell the shares and pay the corresponding tax. Private companies that use RSUs usually add a liquidity-event condition, so the units deliver nothing until an exit. At seed and Series A, options and restricted stock almost always work better for founders and employees, and RSUs matter mainly at later stages when the common stock price makes option costs a real barrier.
