The Section 83(b) Election on Equity Compensation

How it works

Section 83(a) taxes property received for services when it becomes substantially vested, meaning it is transferable or no longer subject to a substantial risk of forfeiture, at that later date's fair market value minus whatever the recipient paid for it. Until that moment, the person who performed the services is not treated as owning the property for tax purposes at all.

Section 83(b) lets that person elect out of the wait-and-see rule. Instead of being taxed later, at vesting, on whatever the stock happens to be worth by then, the election pulls the same calculation forward to the transfer date and taxes the spread at today's value instead. For a founder at formation, or an early employee exercising a freshly priced option, today's value is often close to nothing. Everything the stock does from that point forward becomes long-term capital gain rather than compensation once the holding period is met, and that same holding period, including whatever qualified small business stock exclusion the shares separately qualify for, starts counting from the transfer date instead of from vesting. Skip the election, and the entire run-up between grant and vesting lands in one year as ordinary income, often a large, illiquid, undiversified spike that arrives whether or not there is any cash on hand to pay the tax on it.

The election is not free. It is irrevocable, and if the stock is later forfeited, the tax already paid on the phantom spread does not come back beyond a narrow loss that is often worth nothing, covered under Where it goes wrong below. Electing is a bet that the grant survives to vest and that the company is worth more later than it is today.

The employer's side moves in the same direction. It gets a deduction equal to whatever the recipient included in income, timed to the recipient's inclusion year. Elect, and the employer's deduction is small and lands in the grant year. Skip the election, and the deduction is larger and lands in the vesting year. Whichever timing the recipient's election sets, the employer's deduction follows it automatically.

What counts as a substantial risk of forfeiture

This phrase gets used loosely, and the loose version is wrong often enough to matter, because whether one exists is what decides whether there is anything to elect on in the first place. The regulation ties it to a real, forward-looking condition, ordinarily that the recipient keep performing substantial services into the future. Several things that sound like risk do not qualify by themselves. A decline in the property's value is not a risk of forfeiture; it is just the property being worth less. A restriction that survives forever, such as a fixed buy-sell formula, does not create one on its own either. A plain agreement not to compete does not, absent other facts pointing the other way. Neither does a requirement to hand the stock back if the recipient is fired for cause or convicted of a crime. None of those conditions are about continuing to show up and do the job, which is the thing the regulation is actually testing for.

What this means in Florida

Not much, and I would rather say that plainly than let anyone assume otherwise. Florida has no individual income tax, so nothing about this election changes on the state side, whether the spread is taxed at grant or at vesting. The entire analysis, the grant-date tax, the vesting-date tax, and the eventual capital gain, is a federal question. A Florida resident is not getting a state benefit here that a resident of any other state is not also getting.

Who this applies to

The election only works if actual property changes hands, and only if that property is substantially nonvested at the moment it does. Two grant structures satisfy that in the ordinary course.

• Restricted stock awards. Actual shares are issued, subject to a vesting schedule. The 30-day clock starts on the grant date.
• Early-exercised stock options. The option itself is usually not a taxable event, because a nonqualified option without a readily ascertainable market value is not taxed at grant. The taxable transfer happens at exercise. If the plan allows the option to be exercised before it vests, the clock starts on the exercise date, not on the date the option was originally granted.

Restricted stock units do not qualify, and this is not a close call. The statute says directly that neither section 83 generally, nor any election under it, applies to restricted stock units. Independently of that carve-out, an RSU is only a promise to deliver stock later; no property changes hands at grant, so there is nothing yet to elect on even before reaching the statutory language.

Anyone who performs services can file the election. Being an employee is not a requirement; an independent contractor receiving the same kind of restricted grant can elect too, though whether a given working relationship is really a contractor arrangement or an employment relationship is its own question, and one with consequences well beyond this election.

Electing is an easy call when the grant-date value sits at or near nothing, there is real cash on hand to cover tax on that small spread, and the plan is to stick around through vesting. It deserves more caution when the grant-date value is already meaningful, the position feels uncertain, or there is no outside cash to fund the tax without touching stock that usually cannot be sold yet anyway.

A different regime for partnerships and LLCs

A partnership or LLC profits interest is a different fact pattern from what this page covers, restricted stock and early-exercised options, and I am leaving it out deliberately rather than compressing it into a paragraph. It runs under its own separate body of long-standing IRS guidance, with its own eligibility rules and its own answer to whether an election is even needed. That is a different page.

What it requires

Everything here has to happen inside a single, unforgiving window, or the election never takes effect.

The filing has to be mailed no later than 30 calendar days after the transfer, not business days. Under the timely-mailing rule in Section 7502 a statement postmarked on day 30 is timely even if it arrives later, and if the 30th day lands on a weekend or a legal holiday the deadline rolls to the next business day. That is the entire extension available. There is no reasonable-cause exception and no relief for a late filing, for a structural reason rather than IRS discretion. The regulations split every election into two kinds: a regulatory election, whose due date comes from a regulation or other IRS guidance, and a statutory election, whose due date comes from the statute itself. The discretionary relief the IRS can grant for a good-faith mistake reaches only regulatory elections, by its own terms, and the 30-day deadline sits in the statute itself. Miss the window, and there is no application to file asking for it back.

The filing has to be a written statement containing specific information: identifying details for the taxpayer, a description of the property and how much of it there is, the transfer date, the tax year the election applies to, the restrictions on the property, its total fair market value at transfer figured without regard to any restriction that will lapse, the amount paid, and the resulting includible amount. A standardized IRS form, Form 15620, now exists for this and is the current recommended path, though a compliant written statement drafted to the same specifications still works. It goes to the IRS office where the taxpayer files an income tax return, and a copy has to reach the person or entity the services were performed for; a copy no longer has to be attached to the return itself.

None of this can be reconstructed after the fact. The clock runs from the transfer, which for an early-exercised option means the exercise, not the original grant date. Filing against an unexercised option accomplishes nothing, because nothing has transferred yet.

What you need to document

Proof the filing went out on time

The taxpayer carries the burden of showing the election was timely, not the IRS. Mailing by a method that produces a dated record, and keeping that record, is the difference between a defensible file and an assertion nobody can back up.

A copy furnished to the company

The person or entity the services were performed for is entitled to a copy of whatever was filed. Keep proof that it was actually delivered, not just that it was drafted.

Every data element the election requires

Name and identifying information, a description and quantity of the property, the transfer date, the applicable tax year, the restrictions involved, total fair market value at transfer, the amount paid, and the resulting includible amount. Missing or wrong information invites exactly the scrutiny an otherwise timely filing should not need.

The valuation behind the reported figure

Whatever supports the fair market value used on the filing, whether that is a formal valuation, a recent priced round, or simply the price paid at formation when value and price are the same thing. If the number is ever questioned, this is what answers the question.

Where it goes wrong

This is not a listed or aggressive position. It is a routine, IRS-sanctioned election, and the ways it goes wrong are procedural and factual rather than a fight over whether the underlying law applies.

• Missing the deadline. This is the single most common and the most permanent mistake, and there is no fix for it after the fact. It is not something an amended return can repair later, because there is no return position to amend. The election either existed on day 30 or it never existed at all.
• Filing on the wrong date for an early-exercised option. The clock runs from the exercise, not from when the option was originally granted. An election dated to the grant of an unexercised option is filed against an event that has not happened yet.
• Assuming a restricted stock unit qualifies. It does not, by the statute's own terms, and attempting the election anyway does nothing but create a confusing paper trail.
• Overstating what a failed bet recovers. If the stock is later forfeited, the income tax already paid on the spread is gone, with no deduction for it. Only a narrow loss survives, limited to whatever was paid for the property minus whatever was recovered on the forfeiture, and under the ordinary reverse-vesting arrangement, where the company buys back forfeited shares at the same price the recipient originally paid, that loss usually comes out to nothing at all.
• No proof of mailing. The burden of proving timely filing sits with the taxpayer, which is where audit defense on this election actually happens: a dated mailing record kept from day one, long before any audit starts.

Revocation is not a way around a bad bet, either. Once the election is filed, undoing it takes the IRS's own consent, granted only on a narrow showing that the underlying facts were misunderstood, never because the value moved the wrong way or the recipient changed their mind about the election itself.

A situation where this comes up

The clearest case is a founder at the moment a company is formed. The stock is worth close to nothing because the company has done nothing yet, the cash needed to cover tax on that near-zero spread is trivial, and the plan is to stay and build the thing for years. Filing the election here is close to free optionality. The downside if the venture fails is bounded by how little the stock was worth on day one, and the upside, if the company is eventually sold or goes public, is that years of appreciation are taxed as capital gain instead of wages.

The harder case is an employee joining well after formation, exercising an option on stock that already carries a real, positive spread because the company has proven something and raised money at a real price. Electing means writing an actual check, now, on stock that cannot be sold and might never vest if the job does not work out. The mechanism is identical either way; what changes is whether the recipient has the cash for the bet and enough confidence the position lasts long enough to pay off.

The version I try to catch before it becomes a problem is the one where someone treats the 30-day window as a formality to get to eventually, because the paperwork around a new hire is genuinely busy in the first month. That window does not bend for anyone's onboarding schedule, and by the time it feels urgent, it is usually closed.
