What Is a Section 83(b) Election?
A 30-day decision that can quietly reshape your entire tax bill on founder and startup equity. Here is how it works, when it pays off, and how to file it without mistakes.

30 DAYS
If you have received stock that vests over time as a founder, an early hire, or an advisor you face a tax choice most people don’t even know they have. The Section 83(b) election lets you decide when the government taxes that equity: today, while it is cheap, or later, as it vests and (hopefully) grows in value. Get it right and you may convert a large future income-tax bill into a much smaller one. Miss the window and the choice disappears for good.
The 83(b) election in plain English
A Section 83(b) election is a short written notice you send to the Internal Revenue Service telling it: “Tax me on this equity now, at its current value, rather than later as it vests.” The name comes from Section 83(b) of the Internal Revenue Code, which governs how property transferred in exchange for services is taxed.
The election only matters for equity that is subject to a substantial risk of forfeiture most commonly restricted stock that vests over a multi-year schedule or that the company can buy back if you leave early. Until that equity vests, the tax code normally treats it as not yet “yours” for tax purposes. The 83(b) election overrides that timing.
In one sentence
Filing an 83(b) election means you pay ordinary income tax on the value of your restricted equity at grant usually a tiny number and start the clock on long-term capital gains treatment immediately, instead of being taxed at each vesting date on whatever the equity is worth then.
It is a bet on growth. You voluntarily accept a small, certain tax bill today in exchange for avoiding a potentially much larger, uncertain one later. When the equity climbs in value the entire point of joining an early-stage company that trade usually works strongly in your favor.
How vesting equity is taxed without an 83(b)
When you receive equity as compensation, the IRS treats its fair market value as ordinary income the same category as your salary. The only question is when that income is recognized.
For equity that is fully vested on day one, the answer is simple: it is taxed at grant. But restricted equity that vests over time is different. Because it carries a real risk of forfeiture, the default rule (under Section 83(a)) is that you are taxed each time a portion vests, based on the fair market value on that vesting date.
In a company that is growing, this is exactly when value is rising so each vesting event can trigger a larger and larger ordinary-income tax bill, even though you haven’t sold a single share or received any cash. You may owe real money on paper gains you can’t yet spend.

The practical problem: in a successful startup, your ordinary-income exposure grows in lockstep with the company’s valuation. The 83(b) election exists to short-circuit that.
How the 83(b) flips the tax timing
When you make the election, you choose to recognize all of the equity’s value as ordinary income at grant a single moment when, for most founders and first employees, that value is at or near its floor. From that point forward, the vesting schedule no longer triggers any additional ordinary income.
Two things change in your favor:
Future growth escapes ordinary rates
Any increase in value after the grant is no longer taxed as you vest. It is taxed only when you eventually sell and as a capital gain, not as wages.
Your holding clock starts now
The long-term capital-gains holding period begins at grant for all your shares at once not piecemeal at each vesting date making favorable long-term treatment far easier to reach.
The catch is symmetry: you pay tax up front whether or not the company ever succeeds, and the IRS will not refund that tax if the equity later becomes worthless. The election is a calculated bet, not a free lunch which is why the numbers, and the timing, matter so much.
A side-by-side worked example
Meet Maya, a co-founder who receives 800,000 shares of restricted stock vesting over four years. At grant, an independent valuation pegs each share at $0.002, so the total value of her award is just $1,600. Four years later the company is acquired and her shares are worth $3.00 each $2.4 million. Here is how the two paths compare. (Rates are illustrative; actual brackets vary.)
Two things change in your favor:
Path A — She files 83(b)
Tax paid up front on $1,600
Ordinary tax (≈37%) = ≈ $592
Vesting events = $0 additional tax
On sale: gain = $2,400,000 − $1,600 = $2,398,400 → long-term capital gain
(≈20%) = ≈ $479,680
Total tax ≈ $480,272, the vast majority of it at the lower long-term capital-gains rate.
Path B — She does nothing
Taxed as ordinary income at each vesting date
Ordinary income tax on that (≈37%) = ≈ $333,000
On sale: gain above already-taxed value = $2,400,000 − $900,000 = $1,500,000 → long-term gain (≈20%) = ≈ $300,000
Total tax ≈ $633,000, much of it at high ordinary rates and owed before any liquidity event let her sell shares to pay it.
In this scenario the 83(b) election saves Maya roughly $150,000 and spares her from owing tax on illiquid paper gains during the vesting years. The lesson: when value is low at grant and expected to climb, electing early is powerful. But reverse the outcome if the company folds, Maya’s $592 of up-front tax is simply gone, while Path B would have cost her almost nothing.
Note: These figures are simplified to illustrate the mechanics. Real outcomes depend on your tax bracket, state taxes, AMT, the holding period actually achieved, and the defensibility of the grant-date valuation. Always model your own situation with a qualified advisor.
Who should and shouldn't file
The election is not automatically right for everyone. It rewards low grant-date value and expected growth, and it punishes the opposite. Use this as a starting filter, not a final answer.
Strong candidates
- Founders receiving restricted stock at incorporation, when value is near zero
- Early employees granted restricted stock while the company is still tiny
- Anyone confident the equity's value will rise meaningfully over the vesting term
- Recipients whose tax owed at grant is small enough to pay comfortably out of pocket
Think twice if…
- The grant-date value is already high, making the up-front tax bill painful
- You may leave before vesting you'd have paid tax on shares you never keep
- The company's prospects are genuinely uncertain or likely to decline
- You received stock options (not restricted stock) 83(b) generally doesn't apply to unexercised options
How to file your 83(b) election, step by step
The single most important rule: the election must reach the IRS within 30 calendar days of the equity transfer date. That window includes weekends and holidays, and the IRS has no authority to extend it. Treat the deadline as immovable.
Prepare the election statement
Draft a statement with your name, address, and taxpayer ID; a description of the property; the grant date and tax year; the fair market value at grant; any amount you paid; and a declaration that you are electing under Section 83(b). Sign it.
Mail it to the IRS within 30 days
Send the signed statement to the IRS office where you file your return. Use certified mail with a return receipt so you have dated proof of timely filing this is your only defense if the IRS later loses it.
Give a copy to your company
Provide a copy of the election to the company that issued the equity for its records. If the property was transferred by someone other than your employer, that party should receive a copy too.
Keep proof and check state rules
Retain a copy with your permanent tax records along with the certified-mail receipt. Some states require a copy attached to your state return for that year confirm your state's rule before you file.
Heads up: The IRS no longer requires you to attach the election to your federal return, but mailing it within the 30-day window is mandatory. Always verify the correct filing address on irs.gov before sending, and confirm the fair market value you report rests on a defensible valuation.
Costly mistakes people make with 83(b) elections
Most 83(b) failures aren’t about strategy they’re about execution. These are the errors that turn a smart tax move into an expensive regret.
Missing the 30-day window
The deadline runs from the transfer date, not the date you noticed. There are no extensions and no second chances. A late filing is simply invalid.
Treating "near-zero" as automatic
A very low grant-date value is the result of proper analysis, not a default. Reporting a value with no support invites the IRS to substitute its own — with interest and penalties.
No proof of mailing
Without a certified-mail receipt, you may be unable to prove you filed on time if the election is ever questioned. Regular mail leaves you exposed.
Electing on the wrong instrument
83(b) applies to restricted stock, not to unexercised options. Filing against the wrong instrument or when there's no risk of forfeiture accomplishes nothing.
Electing when value is already high
If grant-date value is substantial, the up-front tax can be a serious cash drain sometimes outweighing the benefit. Run the numbers before assuming "always file."
Forgetting state filing rules
Some states want a copy of the election with your state return. Skipping that step can undermine the treatment at the state level even when your federal filing was perfect.
Frequently asked questions
It is a written notice electing to be taxed on the value of restricted equity at grant rather than as it vests. It locks in your tax cost early, when the value is usually lowest.
Within 30 calendar days of the equity transfer date. The window is strict, counts weekends and holidays, and cannot be extended.
Founders and early employees holding restricted stock while the company’s value is still very low and expected to climb, and whose tax due at grant is small.
You lose the option permanently. The equity is then taxed as ordinary income at each vesting date, based on its value at that time — often far higher.
You must report the equity’s fair market value at grant. A defensible, independent valuation supports that number and protects you if the IRS later questions it.
Only with IRS consent, which is granted only in narrow cases such as a genuine mistake of fact within 60 days. Treat the election as effectively permanent once filed.
