What the 83(b) election is
When you receive restricted stock — shares that vest over time — the default tax rule is that you're taxed as the shares vest, on their value at each vesting date. An 83(b) election lets you flip that: you elect to be taxed now, on the value at grant, and pay nothing more as the shares vest. Any future appreciation is then a capital gain when you sell.
How restricted stock is taxed without an 83(b)
Without the election, each time a tranche vests you recognize ordinary income equal to the shares' value that day. If the company is growing, that value rises over time — so you pay ordinary-income tax on a bigger number with each vesting, exactly when the stock is worth more.
How the 83(b) changes the math
Filing the election taxes you on today's value, which for founder or very-early-stage stock may be almost nothing. You pay a small amount of ordinary income tax now, start the long-term capital-gains holding clock immediately, and convert what would have been years of ordinary income into a single capital gain at sale.
Example: a founder receives 1,000,000 shares worth $0.001 each at grant ($1,000 total). Filing an 83(b) means ~$1,000 of ordinary income now. If the shares are worth $5 each at a later sale, the $5,000,000 of appreciation is long-term capital gain — not ordinary income taxed tranche by tranche as it vested.
The 30-day rule (no exceptions)
The election must be filed with the IRS within 30 calendar days of the grant or transfer. There are no extensions. Miss it and the opportunity is gone permanently. To file, you mail a signed 83(b) statement to the IRS service center where you file your return, keep proof of mailing, and provide a copy to your employer. (Confirm the current filing procedure with your CPA — IRS methods can change.)
When an 83(b) makes sense
- The stock has a very low value at grant, so the upfront tax is small.
- You strongly believe in the upside.
- You early-exercised options and want to start the capital-gains clock.
- You have the cash to pay the (small) tax now.
When it backfires
The election is a bet, and the downside is real. If you forfeit the shares — you leave before vesting, or the company fails — the tax you prepaid is not refundable. And if the stock value at grant is already high, the upfront tax bill can be substantial for shares you may never realize value from. There's no undo.
83(b) and options — the early-exercise angle
The election also comes up when you early-exercise unvested options: filing an 83(b) shortly after exercise can start the holding-period clock and, for ISOs, help manage AMT exposure. This interacts with the rules in our ISO vs NQSO guide.
Common mistakes
- Trying to file for standard RSUs — they don't qualify.
- Missing the 30-day window.
- Not documenting the fair value at grant.
- Filing without the cash to pay the resulting tax.
