The 83(b) Election: When It Saves You Six Figures
An 83(b) election lets you pay tax on restricted stock now, at its grant-date value, instead of at each vesting date when it may be worth far more — so the later appreciation is taxed as a capital gain when you sell, not as ordinary income at vest.
Two catches define the decision: you have 30 days from the grant to file — no extensions, no do-overs — and the election only works for restricted stock and early-exercised options, not RSUs.
There is a one-page letter in startup equity that can be worth six figures. Most people first hear about it after the deadline has already passed — from a coworker who filed one, or a CPA reviewing a vesting schedule and wincing. By then it is too late: the election is filed within 30 days of the grant or not at all.
Figures verified as of November 10, 2026: 2026 federal brackets and capital gains thresholds from IRS Revenue Procedure 2025-32; election procedure from IRS Form 15620 (April 2025 revision). All dollar examples below are simplified illustrations, not anyone's real situation.
What the election actually does
Under the default rule in IRC Section 83(a), restricted stock is not taxed when you receive it, because you could still forfeit it. Instead, you owe ordinary income tax each time a chunk vests, on the spread between what you paid and the fair market value that day. If the company grows, every vest is a bigger tax bill at ordinary rates — up to 37% federally in 2026 (above $640,600 of taxable income single, $768,700 joint).
An 83(b) election flips the timing: you volunteer to be taxed at grant, on the spread between the grant-date value and what you paid. Nothing more is due as the shares vest, and when you sell, the appreciation is a capital gain, with the long-term holding period starting at grant.
That is the entire trick: pay ordinary tax once, on a small number, and convert all future growth into capital gains at 0%, 15%, or 20%. For 2026 the 20% rate starts above $545,500 of taxable income (single) and $613,700 (joint), plus a 3.8% net investment income tax above $200,000 of modified AGI (single) and $250,000 (joint).
Who can use it — and the RSU trap
The election requires one thing: property must actually be transferred to you. That single requirement decides who can file and who cannot.
| Equity type | Property transferred at grant? | 83(b) available? | Default tax timing |
|---|---|---|---|
| Restricted stock award (RSA) | Yes — shares issued, subject to vesting | Yes | At vest, unless elected |
| Early-exercised options | Yes — shares issued on exercise, still unvested | Yes | At vest, unless elected |
| Standard RSU | No — unfunded promise | No | At vest, always |
| Double-trigger RSU (private) | No — shares only at liquidity event | No | At liquidity event |
| Unexercised options | No — options are not property under Section 83 | No | At exercise |
This is the most common and most expensive misunderstanding in equity comp. RSUs are not restricted stock. With an RSA, the company issues actual shares into your name on day one, subject to forfeiture if you leave. With an RSU, you own nothing until vesting — a contractual promise, taxed under Section 451, with nothing for an 83(b) election to attach to. If your grant letter says "restricted stock units," you have no 83(b) decision to make. If it says "restricted stock," you have 30 days.
Early-exercised options work the same way: exercise before vesting, file within 30 days of exercise, and the same math applies. One extra watch-out for incentive stock options: the spread at exercise can count as income for the alternative minimum tax, so run the AMT math before you file.
The six-figure math
Simplified illustration. It assumes the full spread lands in the top bracket for clarity; real tax is progressive, and state tax is separate.
Picture an early employee granted 50,000 shares of restricted stock: fair market value $0.50 per share ($25,000 total), price paid $0.10 per share ($5,000), spread at grant $20,000.
With the election: recognize $20,000 of ordinary income at grant. At a 32% marginal federal rate, that is about $6,400 of tax. The tax basis in the shares becomes $25,000, and the long-term holding clock starts. Four years later the shares are worth $20 each — $1,000,000 total. Sell, and the $975,000 gain ($1,000,000 minus the $25,000 basis) is a long-term capital gain: 20% plus the 3.8% net investment income tax, or about $232,050. Total federal tax: about $238,450.
Without the election: at vest, $995,000 ($1,000,000 minus the $5,000 paid) is ordinary income. At a 37% top rate, that is roughly $368,150 of federal tax — and the basis steps up at vest, so there is no further gain at sale.
| No election | With 83(b) election | |
|---|---|---|
| Tax at grant | $0 | $6,400 |
| Tax at vest | ~$368,150 (ordinary income) | $0 |
| Tax at sale | $0 | ~$232,050 (long-term capital gain) |
| Total federal tax | ~$368,150 | ~$238,450 |
| Saved by the election | ~$129,700 |
That is the six figures in the headline: roughly $130,000 saved, because about a million dollars of appreciation was taxed at 23.8% instead of 37%. The saving scales with the growth. For founders, who often buy shares at formation-date value of a fraction of a cent, the spread at grant is near zero and nearly all the appreciation becomes capital gain.
One honest caveat: the saving above is federal. Some states tax capital gains as ordinary income — California is the big one — so there the election saves federal tax only.
The 30-day deadline is absolute
The clock runs from the transfer date — usually the grant date for restricted stock, or the exercise date for early-exercised options — not from when you sign the paperwork or the board approves the grant. You have 30 calendar days. If day 30 falls on a weekend or federal holiday, it rolls to the next business day. Otherwise there is no extension, no relief for reasonable cause, and no do-over. The IRS takes the position that it lacks authority to grant late relief.
The election is also irrevocable once filed. It can be revoked only with the IRS's consent, granted almost never — typically only when the election was made under a mistake of fact, and the request must come within 60 days of discovering the mistake.
How to file in 2026
The IRS released a standardized form in late 2024 — Form 15620, Section 83(b) Election (April 2025 revision) — and in July 2025 opened online filing through an IRS online account. Mail or a self-drafted letter meeting Treasury Regulation 1.83-2 also work. Use only one method.
- Online: file Form 15620 through your IRS online account (identity verified through ID.me). You get immediate confirmation of receipt — worth a lot on a hard 30-day deadline.
- By mail: send the signed form or statement to the IRS service center where you would file your federal return — Austin, Kansas City, or Ogden, depending on your state — using the "no payment" address. The postmark date counts, so a letter postmarked on day 30 is timely. Send it certified mail with return receipt and keep the proof.
- Copy to your employer: you must furnish a copy to the company. Keep a copy for your own records too.
- No return attachment: final regulations (T.D. 9779) eliminated the requirement to attach a copy to your Form 1040 for property transferred on or after January 1, 2016. You still report the income recognized on the election on that year's return.
Confirm the grant-date fair market value with the company before you file — for a private company that is the 409A valuation — because that number is the amount you are taxed on.
The three ways it backfires
1. You forfeit the shares. Leave before vesting, and the tax you paid at grant is gone. The statute is blunt: no deduction is allowed for the income you recognized. Your only loss is a capital loss equal to what you actually paid out of pocket, minus anything you get back — and capital losses offset only $3,000 of ordinary income per year. If you paid almost nothing for the shares, the deductible loss may be close to zero.
2. The value falls. File on stock worth $10 a share, watch it fall to $2, and you paid ordinary tax on value you will never see. The smaller the spread at grant, the cheaper the bet; a large spread means a large, non-refundable upfront tax bill.
3. You owe tax on money you cannot touch. The shares are illiquid — you cannot sell them to pay the tax. For early-exercised ISOs, the spread at exercise can also count as AMT income, creating a bill with no cash from the shares to pay it. Never file an election you cannot afford out of cash you can afford to lose.
The decision test
| File the election when… | Think twice (or skip it) when… |
|---|---|
| The spread at grant is small — ideally near zero | The spread at grant is already large |
| You expect meaningful appreciation | The company's outlook is genuinely uncertain |
| You are likely to stay through vesting | You might leave before the shares vest |
| You can pay the tax from cash you can afford to lose | Paying the tax would strain your finances |
| The shares are restricted stock or early-exercised options | Your grant is RSUs — no election is available |
When all five conditions on the left hold, the election is close to automatic — the founder case, and the early-employee case while the 409A is still low. When any condition on the right holds, it is a real gamble, and the price of losing is tax paid on value you never receive. If you do file, do it the week the grant lands, not the week the deadline lands.

83(b) election FAQ
Can I make an 83(b) election for my RSUs?
No. An 83(b) election requires that actual shares be transferred to you. An RSU is an unfunded promise to deliver shares in the future, so there is nothing for the election to attach to. RSUs are taxed under Section 451 and are always taxed at vesting. The election works for restricted stock awards and early-exercised options.
What happens if I miss the 30-day deadline for an 83(b) election?
The election is gone for that grant, permanently. The 30-day deadline has no extensions, no grace period, and no relief for reasonable cause — the IRS takes the position that it lacks authority to grant late relief. You fall back to the default rule: ordinary income tax on the spread at each vesting date.
What happens if I leave and forfeit shares after filing an 83(b) election?
The tax you paid is gone. The statute allows no deduction for the income you recognized on the election, and you cannot amend the earlier return to undo it. Your only consolation is a capital loss equal to what you actually paid for the shares, minus anything you get back — subject to the $3,000-per-year cap against ordinary income. If you paid almost nothing for the shares, the deductible loss may be close to zero.
Do I still need to attach a copy of the 83(b) election to my tax return?
No. For property transferred on or after January 1, 2016, final regulations (T.D. 9779) eliminated the requirement to attach a copy to your Form 1040. What still matters is filing with the IRS within 30 days and giving a copy to your employer. Keep a copy with your tax records as good practice.
The bottom line
The 83(b) election is a one-time, 30-day decision to pay a small tax now so years of growth are taxed as capital gains instead of ordinary income. When the spread at grant is small and the company grows, it can save six figures. When the shares are forfeited or the value falls, the tax you paid is gone for good. Check which kind of equity you hold — RSUs cannot use it — confirm the grant-date value, and file the week the grant lands.
