The 83(b) Election: Why Founders and Early Employees Have 30 Days to Act on Restricted Stock

Filing an 83(b) election means telling the IRS you want to be taxed on your restricted stock today, at today's value, rather than when it vests. For a founder receiving stock worth a fraction of a cent per share, that decision can shift years of appreciation from ordinary income rates into long-term capital gain territory. The window is exactly 30 calendar days from the grant date. Not business days. Days.

What Restricted Stock Is and Why the Default Is a Problem

Restricted stock is an actual equity grant, not a promise of equity. You own shares from day one, but they are subject to a vesting schedule: leave before you vest, and you give them back.

Under IRS default rules (Section 83), you are taxed as each tranche vests, at ordinary income rates, on the fair market value on that vesting date. If the company has grown meaningfully by year two or four, you are paying ordinary income tax on a number that did not exist when you accepted the grant. For founders and early employees, that default is expensive by design.

How the 83(b) Election Resets the Clock

The election is a one-page letter to the IRS, filed within 30 days of the grant, that says: tax me now, on today's value.

If you are a founder receiving one million shares at $0.001 par value, your taxable income at election is $1,000. Every dollar of appreciation from that point forward is a capital gain, and if you hold the shares more than a year past the grant date, it is long-term capital gain, taxed at 15 or 20 percent rather than 37 percent ordinary income rates. The vesting schedule still governs forfeiture risk. The tax clock started at grant.

This is where restricted stock behaves differently from RSUs. RSUs cannot take an 83(b) election because you do not own shares at grant. The parent guide on equity compensation explains that distinction in full.

The Scenarios Where the Election Hurts Instead of Helps

Two situations make the election the wrong choice.

First: the stock declines or you leave. If you file the election, pay tax on $50,000 of grant-date value, and forfeit the shares before vesting, you are left with a capital loss and the tax paid at grant does not come back.

Second: a high grant-date value. The election triggers a real tax bill today. The future capital gain treatment may still be worth it, but the arithmetic has to pencil out.

The election also interacts with ISO grants and AMT. This lives in the Soil layer of a plan, where tax architecture decisions have compounding consequences. See the Sporos Doctrine for how these interactions work across a full plan.

A Founder Who Filed vs. One Who Didn't

Two co-founders each receive 1,000,000 shares at $0.001 per share. Four years later, shares are worth $5 each.

Founder A filed the 83(b) election. Her taxable income at grant was $1,000. Her $4,999,000 of gain is long-term capital gain at 20 percent. Tax owed: roughly $1,000,000.

Founder B missed the window. Quarterly vesting events generate ordinary income as the company appreciates toward its Series B. Her effective rate on much of that same gain is closer to 37 percent. The difference is real money, not a planning footnote.

Frequently Asked Questions

Can I file an 83(b) election on RSUs?

No. RSUs are a promise to deliver shares in the future, not a transfer of property at grant. The election applies only to restricted stock where you receive shares subject to forfeiture.

What happens if I miss the 30-day window?

The opportunity is permanently lost. Vesting events revert to ordinary income events at their then-current fair market value, and the IRS has granted no relief for late filings.

Does the 83(b) election affect my vesting schedule?

No. The vesting schedule and forfeiture conditions remain exactly as written in your grant agreement. The election changes only when and how the gain is taxed.

Is the election worth it if the grant-date value is not negligible?

It depends on expected growth rate, your marginal rate, and how much you would pay today versus the projected savings on appreciation. At meaningful grant-date values, this requires your specific numbers.

What to Do Next

What decides this is how much the company is expected to grow and how confident you are in staying through the vesting schedule. If the grant-date value is truly minimal and the upside is real, the election is almost always the right answer.

Where it goes wrong is the forfeiture scenario combined with a non-trivial grant-date value. People file the election correctly, pay the tax, and then leave before vesting. The tax paid does not come back.

Worth a conversation if you are within your 30-day window right now, if you hold both restricted stock and ISOs and are unsure how the two interact in an AMT year, or if a vesting cliff is approaching and you have never stress-tested what the ordinary income event looks like at current valuations.
