The Thirty-Day Window

What the election does

When you receive equity subject to a substantial risk of forfeiture, typically a vesting schedule, the default treatment is that you recognize ordinary income as it vests, on the value at each vesting date.

An election under section 83(b) reverses the timing. You elect to recognize the value at grant instead, immediately, and nothing further is recognized as it vests. Subsequent appreciation becomes capital gain on disposal rather than ordinary income on vesting, and the holding period starts at grant.

For a founder receiving stock at formation, when the value is nominal, this converts a potentially enormous future ordinary income item into a small present one. That is the case for which the provision is famous.

The deadline is absolute

The election must be filed within thirty days of the transfer. Not thirty business days, not thirty days from when somebody told you about it, and not thirty days from when your lawyer sent the paperwork.

When filing is the wrong call

The election is treated as reflexively correct in founder circles, and it is not. Three situations where it is questionable or wrong.

• The value at grant is already significant. You are accelerating a real tax bill on shares you cannot sell and may never be able to sell, funded from your own cash.
• You may not stay. If you forfeit unvested shares after electing, you generally cannot recover the tax you paid on them. You will have paid ordinary income tax on equity you never received.
• The company may not succeed. Paying tax at grant on stock that later becomes worthless converts a non-event into a permanent cost, and the loss treatment available afterwards rarely makes you whole.

The election is a bet that the equity will be worth more later and that you will still hold it. It is usually a good bet at formation and a progressively worse one afterwards.

Where this lands

1. 01Establish the transfer date the moment you receive restricted equity. The clock starts there, not at signature and not at board approval.
2. 02Decide inside the first week, not the fourth. A decision made under deadline pressure with incomplete information is how the wrong call gets made in both directions.
3. 03File it correctly and keep proof. Certified mail with return receipt, a copy retained, and a copy to your preparer. Disputes about whether an election was filed are surprisingly common and turn entirely on evidence.
4. 04If you are being granted equity repeatedly, build this into the process. Every new grant is a new thirty days.
