An 83(b) election lets a U.S. taxpayer include the value of certain substantially nonvested property in income at transfer instead of waiting for vesting.
An 83(b) election is a U.S. federal tax election that lets a service provider include the value of certain substantially nonvested property in income when the property is transferred rather than when it later becomes substantially vested. The amount generally included is the property’s fair market value at transfer, ignoring restrictions that will lapse, minus the amount paid for it.
Without an election, substantially nonvested property transferred for services is generally included in income as it becomes transferable or is no longer subject to a substantial risk of forfeiture. With a timely election, the service provider generally includes the transfer-date value instead.
| Question | No 83(b) election | Timely 83(b) election |
|---|---|---|
| Compensation measurement date | Generally when the property becomes substantially vested | Transfer date |
| Compensation amount | Fair market value at vesting minus amount paid | Fair market value at transfer minus amount paid |
| Later appreciation before vesting | Can become compensation income as restrictions lapse | Generally not recognized as compensation solely because vesting occurs |
| Basis | Generally amount paid plus compensation income recognized | Amount paid plus compensation income recognized at transfer |
| Holding period | Generally begins when property becomes substantially vested | Generally begins at transfer |
| Forfeiture downside | No compensation inclusion for property forfeited before vesting under the normal rule | Prior income inclusion is generally not reversed; loss rules are limited |
The election changes timing and character, not the underlying business risk. The property can still decline, be forfeited, or remain impossible to sell.
| Arrangement | 83(b) election generally relevant? | Reason |
|---|---|---|
| Restricted stock transferred at grant | Yes, if substantially nonvested | Actual property has been transferred subject to forfeiture conditions. |
| Stock acquired through early exercise of an option | Potentially | Exercise transfers stock that may remain subject to vesting or repurchase. |
| Vested stock | Usually no new need | The property is already substantially vested when transferred. |
| Unexercised stock option | No | IRS guidance states the election cannot be made for a statutory or nonstatutory option itself. |
| Unsettled RSU | Generally no | A contractual promise is normally not a current transfer of property. |
| Phantom stock | Generally no | Hypothetical units ordinarily do not transfer actual property at grant. |
An award’s marketing label is not decisive. The legal question is whether property was transferred in connection with services and remained substantially nonvested at that time.
Assume a founder buys 10,000 restricted shares for USD 1 per share, equal to their fair market value on the transfer date. The shares cliff vest after three years and must be sold back for the original price if the service condition is not completed.
10,000 x USD 1 = USD 10,000USD 10,000USD 10,000 - USD 10,000 = USD 0If the shares are worth USD 8 each when they vest, the vesting event generally does not create USD 70,000 of additional compensation income solely because the restriction lapsed.
If all shares become substantially vested when worth USD 8 each:
10,000 x USD 8 = USD 80,000USD 10,000USD 80,000 - USD 10,000 = USD 70,000The example shows the possible upside of electing when transfer-date value is low. It does not show the downside. If the founder instead pays USD 1 per share when fair market value is USD 3, the election would generally accelerate USD 20,000 of compensation income. A later forfeiture or collapse in value would not automatically refund tax paid on that inclusion.
Actual results depend on valuation, payroll reporting, state and local law, capital-gain rules, dividends, restrictions, and transaction facts.
The current IRS process is:
The election must identify the taxpayer, property, transfer date, tax year, restrictions, fair market value, amount paid, and amount included in income, along with the required copy statement. Form 15620 is provided for convenience; a valid compliant statement remains permitted under current IRS guidance.
Taxpayers are no longer generally required to attach a copy of an 83(b) election to the income-tax return. Treasury removed that requirement for property transferred on or after January 1, 2016. The taxpayer must still file the election with the IRS within 30 days, provide required copies, and retain records supporting income and basis.
Attaching a copy to a return does not replace timely filing of the election itself.
The election amount is generally:
fair market value at transfer - amount paid for the property
Fair market value is determined without considering restrictions that will lapse, although restrictions that never lapse can be treated differently. For a private company, the valuation should be supported by contemporaneous evidence rather than an expected future financing or an informal estimate.
Even when the calculated income is zero, filing can still be important because the election documents the taxpayer’s choice to apply Section 83(b) to the transferred property.
An 83(b) election cannot generally be revoked without IRS consent. IRS Publication 525 states that consent is given only for a mistake of fact about the underlying transaction, not simply because the share value fell or the taxpayer changed their mind.
Missing the filing deadline is also not cured by attaching an election to a later tax return. Anyone facing an incorrect, incomplete, or late election should obtain qualified tax advice promptly rather than assume a routine extension exists.
