An 83(b) election is a one-page letter to the IRS, filed within thirty days of receiving restricted stock, that chooses to be taxed on the shares' value at grant instead of as they vest — and for early employees and founders receiving stock worth pennies, it is almost always the right choice, because the alternative taxes the shares at whatever they are worth on each vesting date. The election exists because of Section 83 of the Internal Revenue Code, which otherwise treats vesting restrictions as meaning the recipient has not really received the property until it vests. File the election, and the whole grant is taxed immediately at grant-date value, with all later appreciation taxed as capital gain at sale. Miss the thirty-day window and the election is gone — no extensions, no forgiveness. This article explains who it applies to and how it works.

Who Faces the 83(b) Decision?
The election applies to restricted stock — actual shares subject to vesting or forfeiture — not to stock options. The classic recipients are founders at incorporation (whose shares are worth almost nothing and who should file essentially without exception) and early employees granted restricted stock instead of options, common in the first hires before a formal option plan exists. Option holders face the decision only when exercising early: exercising unvested options makes the recipient an owner of restricted stock, and the 83(b) clock starts at exercise. Recipients of stock through repurchase-right founder agreements — including those with vesting imposed by investors — face it as well. For recipients of plain options who do not exercise, there is nothing to elect.
What Does Filing Actually Change?
Without the election, each vesting date is a taxable event: the recipient recognizes ordinary income equal to the shares' fair market value that day minus anything paid. For a company whose value rises, that means tax bills on paper wealth the recipient cannot spend — shares not yet sellable, taxed at ordinary rates as they vest, a problem that compounds into a genuine crisis when a company's value runs up before liquidity. With the election, the entire grant is taxed once at grant-date value — for early-stage companies, often pennies per share, producing a de minimis tax bill — and every subsequent gain is capital gain, at preferential rates, when the shares are eventually sold, with the holding period starting at grant. The trade is honest: the recipient pays tax on value that might evaporate, and cannot claim a loss for the amount included in income if the shares become worthless. For near-zero-value grants, that trade is trivially favorable; for grants with real value, it deserves actual computation.
How Is the Election Made?
Mechanics are strict. The election is a signed statement identifying the taxpayer, the property, the transfer date, the restrictions, and the value included in income — the IRS and several publishers provide template wording. It must be filed with the IRS within thirty days of the grant date: postmarked within the window, mailed to the service center, with proof of mailing kept forever. Copies go to the employer and are attached to the recipient's next tax return. The thirty-day deadline has no extensions and no late relief — courts have consistently upheld the deadline — which is why the standard practice is to prepare the election the same day the grant documents are signed. Companies onboarding recipients of restricted stock should hand each one the form and the instructions; recipients should not assume anyone else handled it.
What Happens Without One?
The failure mode is expensive and common enough to be a startup ritual: an early hire with restricted stock skips the election, the company's 409A value climbs through successful rounds, and each vesting tranche triggers ordinary income tax on appreciation the hire has not banked. At acquisition, the shares still pay off, but the tax paid along the way exceeded what capital treatment would have cost, sometimes by large multiples. The lesson: the 83(b) window is one of the few truly irreversible thirty-day deadlines in tax — identify whether a grant is restricted stock, decide quickly, and file with proof on day one.
