Key Takeaways
- An 83(b) election taxes restricted shares at grant-date value instead of at each vest, locking in today's (ideally negligible) price.
- The deadline is 30 days from the stock's transfer, no extensions, no exceptions, and filing proof is on you.
- It is a bet that the stock rises: you prepay a small known tax to avoid a large future one, and forfeit it if you leave early.
Restricted stock, actual shares subject to vesting, common for founders and very early employees, is normally taxed as each tranche vests, at whatever the shares are worth then. For a startup that works, that default is a disaster: each vest of now-valuable shares is ordinary income, with tax due on paper wealth you cannot sell. The 83(b) election flips the timing: file within 30 days of receiving the shares, pay ordinary tax on their full value today, and all future appreciation becomes capital gain, taxed only when you sell.
When the shares are worth pennies, the election costs almost nothing and changes everything downstream.
The Mechanics and the Merciless Deadline
The election is a short statement filed with the IRS within 30 days of the share transfer, with a copy retained and, typically, one to your employer. Thirty calendar days, from transfer, not from when you learned about it, and there is no relief for missing it. File by certified mail or the IRS's electronic option, keep proof of mailing, and confirm receipt in your records; the burden of proving a timely election is yours, potentially years later in diligence for an acquisition. Founders should treat the 83(b) as part of incorporation hygiene, done the same week stock is issued.
The Math of When It Wins
Classic case: a founder receives shares worth $2,000 total at formation. Electing means recognizing $2,000 of income now, trivial tax, and starting the long-term capital-gains clock (and the five-year QSBS clock, covered in the QSBS guide) immediately. Without the election, vests over four years at rising valuations could generate six or seven figures of ordinary income with no liquidity to pay it. The election loses when the stock declines or you forfeit unvested shares after leaving, the prepaid tax is not refunded, which is why it suits low-current-value, high-uncertainty grants: small known cost, huge avoided risk.

Where Employees Meet It
Regular option holders meet the 83(b) through early exercise: some companies allow exercising options before they vest, receiving restricted shares, and filing an 83(b) on the (ideally zero) spread. Done at a low 409A value, this starts capital-gains and QSBS clocks years early at minimal tax. The risks are real cash out the door for illiquid shares and forfeiture-with-repurchase if you leave, usually at your cost, so size it by the private-company sizing rule: only money whose loss changes nothing.
Common Failure Modes
The catastrophic one is silence: not knowing the window existed until day 40. Others: filing without proof and failing diligence later; electing on already-valuable shares and writing a large check for a company that then stumbles; and confusing RSUs, which cannot take an 83(b), with restricted stock, which can. If you are receiving founder shares or early-exercising options this month, this is a this-week conversation with your planner and CPA, not a next-quarter one.
Frequently Asked Questions
Can I file an 83(b) for RSUs?
No. RSUs are a promise of future shares, not a current transfer of property, so there is nothing to elect on. The election applies to restricted stock and early-exercised options.
What does filing cost me if the startup fails?
The tax you prepaid on the grant-date value, usually small by design, plus any exercise cost. You can generally claim a capital loss on your investment when the shares become worthless.
I missed the 30-day window. Any fix?
No retroactive relief exists. The fallback is planning around vest-date taxation: modeling the income, timing sales where possible, and occasionally restructuring future grants properly.
