Imagine a startup founded by Elon Musk, Sam Altman, Barack Obama, and Dolly Parton. Obviously it is on the cover of every magazine. Before the company does anything else, it hires a 22-year-old engineer two months out of undergrad and grants her 10 percent of the company in common stock, fully vested. The company closes a funding round the next day at a one-trillion-dollar valuation. Investors take common stock (no preferred, no liquidation preference, no protective provisions) because the company is that hot.
She is now the owner of $100 billion of common stock. [S: yay.]
She is also, as a matter of federal tax law, in the worst position of her life. [M: sad trombone.]
What happens the moment the stock hits her hands
Under section 83 of the Internal Revenue Code, when stock is transferred to an employee in exchange for services, the fair market value of that stock on the date it vests is ordinary compensation income in that year. Not capital gains. Not deferred. Ordinary.
Her taxable income for the year is, in round numbers, $100 billion. Her federal tax liability is around $37 billion. California, where she lives, wants another $13 billion. Medicare and payroll add-ons take more. She owes, conservatively, $50 billion in tax by April 15.
She has exactly zero dollars in cash. The stock is private and illiquid. Her grant agreement prohibits transfers entirely without the company’s prior written consent. No sales. No gifts. No pledges. No secondary transactions to anyone. A right of first refusal in favor of the company sits on top of anything the company would otherwise approve. She cannot sell her way out of the tax bill. The IRS is not moved by the argument that her wealth is on paper. [M: this specific part isn’t a hypothetical edge case.]
This is the phantom income problem. In the extreme it is genuinely career-ending.
The boring version is also bad
That example is absurd on purpose. No real startup would ever grant 10 percent of a one-trillion-dollar company as fully-vested common stock to a fresh hire. But the underlying tax mechanics are exactly the same when a normal Series A startup grants a normal early employee a normal chunk of stock outright.
A 22-year-old hire at a $200M company granted 0.5 percent of common stock outright has roughly $1M of ordinary income in the year the grant vests. At federal and state combined rates, the tax bill is around $400,000. The stock is illiquid. The employee is making $120,000 in salary. The math isn’t bankruptcy, but it is a material hardship, and it is the employee, not the company, who has to find the cash.
This is why almost no early-stage company grants common stock to employees outright. It isn’t stinginess. It is section 83.
What companies do instead
Every structure in startup equity is a workaround for the same problem: how do you give an employee ownership without creating a tax bill they cannot pay on an illiquid asset?
Options. The grant of an option is not a taxable event. The employee pays tax only at exercise (for non-qualified options) or at sale (for incentive stock options, subject to AMT on exercise). The employee controls the timing. In theory the employee can wait until there is a market for the stock (an acquisition, an IPO, a tender) before triggering the tax.
Restricted stock with an 83(b) election. For very early employees at very low valuations, the company grants actual stock, but unvested, and the employee files an 83(b) election within 30 days. Section 83(b) lets the employee pay tax on the grant at current value, when the stock is worth almost nothing, rather than at each vesting tranche as the value grows. This is how founder stock works. It only works when the current value is trivially small. [S: 30 days. Not 31. Not “around 30.”]
RSUs. At later-stage private companies and public companies, restricted stock units. No stock at grant, no tax at grant. Tax at settlement, typically at vesting, or at a later liquidity event, depending on the structure. The double-trigger RSU at a late-stage private company is specifically designed so the tax event does not hit until the shares are actually sellable.
Each of these is a different answer to the same question. Every one of them exists because section 83 is otherwise brutal.
What most employees do not understand
Three things worth saying plainly.
You do not actually own the company when you have options. You have a contractual right to buy shares at a set price during a set window. If you leave, that window usually closes in 90 days. If you cannot come up with the cash to exercise in 90 days, your equity evaporates. [M: read the post-termination exercise provisions before you sign.]
The 409A valuation is not the valuation. The strike price on your options is set by a 409A, which is an independent valuation of the common stock. The preferred stock the VCs own is worth substantially more. Your grant is priced off a number that is deliberately lower than the headline round valuation, and the company is legally required to keep it that way.1
The tax-planning decisions are consequential. Early exercise, 83(b) elections, ISO limits, AMT exposure, and quick-sale disqualifying dispositions are all real and all timing-sensitive. Done right, they can mean the difference between a 15 percent long-term capital gains rate and a 40-plus percent ordinary rate. Done wrong, they can mean a large tax bill with no cash to pay it.
Issuing equity is one of the highest-stakes decisions early-stage companies make. The mechanics matter more than the headline percentage.
Talk to a Talairis attorney →Get counsel before you do anything
Equity compensation is one of the few areas of the tax code where the difference between a good outcome and a bad one is almost entirely about paperwork filed at the right time with the right numbers. Thirty days late on an 83(b) is fatal. Exercising ISOs at the wrong point in the calendar year can trigger AMT that another month of timing would have avoided. Granting options without a current 409A on file can expose the whole grant to section 409A penalties, which are worse than ordinary income treatment.
This is not DIY territory. If you are a founder, have your equity plan drafted and your grant agreements reviewed by a lawyer who does this work every day. If you are an employee, do not sign an offer with meaningful equity without having counsel explain what it actually is and what elections you need to make and when.2 The worst outcomes in equity compensation are almost all caused by people who assumed the company’s form document was fine and did not read it until it was too late.
A closing thought
No startup actually gives you stock.
Not out of greed. Not out of bureaucratic inertia. The tax code makes giving you stock the worst thing they could do for you. Everything else is a workaround.
- Founders and early employees miss the 30-day 83(b) window for every reason imaginable. Mailed to the wrong IRS service center. Postmarked on day 31. Sent certified but the client never picked up the return receipt. The election times out, the stock is treated as transferred at each vest, and the recipient pays ordinary income on every tranche as the value grows. There is no fix. ↩
- Every equity grant carries a calendar of timing-sensitive elections, and every offer letter quietly puts the burden of catching them on the employee. ↩
