What Is the 83(b) Election Deadline and Why Do 30 Days Matter?
Last reviewed: August 2026
The 83(b) election deadline is 30 days from the day your restricted stock is granted, or from the day you early-exercise options before they vest. There is no extension and no late filing that fixes it. Miss the window and you have quietly agreed to be taxed at ordinary income rates on every dollar your equity gains while it vests, instead of at capital gain rates.
Key Takeaways
- The clock starts at grant or early exercise, not at the tax filing deadline, and it runs 30 calendar days.
- Filing shifts future appreciation from ordinary rates to long-term capital gain rates of 0%, 15%, or 20%.
- The top federal ordinary rate reaches 37% in 2026, which is the gap the election is closing.
- The election is a bet: prepaid tax is not refunded if the company fails or you forfeit unvested shares.
About the Author: Jeff Judge, CFP®, AEP®, ChFC®, CLU® is Managing Partner of Chesapeake Financial Planners in Forest Hill, Maryland. He has been helping families and business owners in Harford County and the Baltimore metro area navigate equity compensation and startup exits since earning his CFP® certification in 2013, by using Chesapeake's signature process, the R.U.D.D.E.R. Method™. "I have watched people hand the IRS tens of thousands of dollars they never had to pay," Jeff says, "because of a one-page form they did not know existed."
What does an 83(b) election actually change about your taxes?
It changes when you are taxed, and that changes the rate. When you receive stock subject to vesting, the default rule taxes you as the shares vest, at ordinary income rates, on whatever the shares are worth on each vesting date. If the company grows, your tax bill grows right alongside it, tranche by tranche, all of it taxed like salary.
The election flips the timing. You tell the IRS in writing that you want to be taxed now, at grant, on today's value. For a founder or a very early employee, that value is often a rounding error. You pay ordinary income tax on that small number once, and from that point forward the growth is treated as capital gain. Hold the shares long enough and it becomes long-term capital gain.
Put real numbers on it. Say you join early and receive 50,000 shares of restricted stock worth two cents each, so $1,000 of value at grant. File the election and you report $1,000 of ordinary income this year. Four years later the shares are worth $8 apiece. Without the election, each vesting slice is taxed as ordinary income at that climbing price. With it, the entire run from two cents to $8 is capital gain. Same shares, same outcome for the company, very different tax bill for you.
| Default treatment | With an 83(b) election | |
|---|---|---|
| When you are taxed | At each vesting date | Once, at grant |
| Taxed on | Value on each vesting date | Value at grant |
| Rate on later growth | Ordinary income | Capital gain |
| Cash needed for tax | In vesting years, when shares may be unsellable | Up front, usually small |
This is not a loophole. It is a timing choice the code hands you, and the default is the worse of the two options for most people who qualify. The mechanics sit inside the broader picture we lay out in our equity compensation planning guide.
Why does the default rule cost so much?
Two things make it painful, and they stack.
The first is the rate gap. Ordinary income rates run well above long-term capital gain rates, which top out at 20% federally while the top ordinary bracket reaches 37%. When the appreciation on your shares gets taxed as ordinary income instead of capital gain, you are paying the more expensive rate on the growth for no reason other than a form you skipped.
The second is timing. Restricted stock vests in the years you are presumably still working and drawing a salary. That vesting income lands on top of your paycheck, in exactly the years the stock is climbing, and can push you into higher brackets right when the equity is worth the most. You get taxed at your worst marginal rate on your best asset.
Then there is the cash-flow trap, which is the one that actually keeps people up. If the company is still private, you cannot sell. There is no market. The default rule still hands you a tax bill on the paper value as each tranche vests, so you owe real cash on gains you cannot touch. I have seen people scramble to cover a five-figure tax bill on stock they could not legally sell a single share of. Filing at grant, when the value is tiny, sidesteps that entire mess.

Who can file an 83(b) election, and who cannot?
This is where half-knowledge does real damage, so read this part twice. The election applies to stock you actually receive that is subject to vesting. That means restricted stock awards, the kind founders and very early employees get, and shares you receive from the early exercise of stock options before they vest. Those are the two cases.
It does not apply to standard RSUs. An RSU is a promise to deliver a share to you later, once it vests. Until that happens you do not own property, and if there is no property there is nothing to make an election on. If someone confidently tells you to file an 83(b) on your RSUs, they do not understand the instrument, and the paperwork goes nowhere. The vesting mechanics that do matter for RSUs are covered in our piece on double-trigger RSUs at a private company.
Early exercise deserves its own paragraph, because it is the case people understand least. Some option plans let you exercise before your options vest, which means you pay to buy shares now and receive stock still riding the vesting schedule. On its own that sounds like paying early for no reason. The election is the entire point of doing it. You exercise while the spread between your strike price and current value is small or zero, file inside the window, and start the capital gain clock on shares that have barely moved. Skip the election and early exercise loses most of its purpose.
So what is step one? Not filing anything. Step one is knowing what you actually hold. Founders and the first handful of employees typically have restricted stock. People who join later typically have RSUs. Option holders sit in the middle, and the question only comes alive for them if the plan allows early exercise and they take it. If you cannot say with certainty which describes your grant, nail that down this week, because everything else depends on it.
What is the real risk nobody mentions?
Search this topic and you will find a pile of posts treating the election as free money you would be foolish to skip. That framing is incomplete, and incomplete guidance on irreversible decisions is how people get hurt.
The election is a bet. When you file, you prepay tax on shares that might one day be worth nothing. If the company folds, or you leave before your shares vest and forfeit them, you do not get that prepaid tax back. There is no tidy loss deduction that makes you whole for ordinary income tax paid on stock you never kept.
Run the downside honestly. Suppose you early-exercise a large block at a company already valued high enough that your spread triggers a real five-figure tax bill, and you file. Two years later a better offer arrives and you leave before the shares fully vest, forfeiting the unvested portion. The prepaid tax is gone and the shares are gone with it. That scenario is not the common one, but it is not rare either, and it is exactly the case the free-money crowd leaves out. What happens to equity when you walk away is worth understanding before you sign, which is why we wrote about what happens to stock options when you leave a job.
The size of the grant changes the whole calculation. For a founder holding stock with a basis of essentially zero, the tax paid at grant is trivial and the bet is close to free, so filing is usually a clear call. For someone early-exercising a large block at a company that already carries a real valuation, the upfront tax and the cash at risk are both meaningful, and the honest answer is that it depends: on the dollar size of the grant, the current valuation, your conviction in the company, and how much cash you can afford to tie up and possibly lose. Anyone giving a blanket yes or no without asking those questions is guessing.
How do you avoid blowing the 83(b) election deadline?
If you decide the election makes sense, execution is where people still trip. The 30-day clock starts at grant for restricted stock, or at exercise for early-exercised options. It does not start when you get around to it, and it has nothing to do with the April filing deadline. Thirty calendar days, counted from the grant or exercise date.
A few habits keep this from going wrong:
- File in the first week, not the fourth. Mail and life both get in the way, and there is no grace period waiting for you.
- Send the signed election to the IRS office where you file your return, and keep proof of mailing.
- Include a copy with that year's tax return.
- Loop in a tax professional before you file rather than after, since the election interacts with your broader picture.
- Raise the question before you sign anything, while you are still negotiating the offer.
Does living in Maryland change the math? Partly. Maryland starts from your federal income and does not apply a preferential rate to long-term capital gain, so the rate arbitrage the election creates is a federal benefit rather than a state one. What still matters here is the stacking. Maryland's top marginal rate reaches 6.5% and Harford County adds a local income tax of 3.06% on top of it. For someone at a Baltimore-corridor biotech or a Hopkins spinout, a default-rule vesting event concentrates a large slug of income into a single year at combined federal, state, and county rates. Spreading that exposure is part of why the timing question deserves attention before the grant is signed, not after.
Deciding whether to file, and sizing the cash you are willing to put at risk, is exactly the kind of sequencing question the R.U.D.D.E.R. Method™ is built for. It is Chesapeake's six-step process for turning a financial picture into a plan you can follow, and it starts with understanding what you actually hold before anyone recommends a move. The founder-focused version of this decision is covered in our companion piece on the 83(b) election.
Frequently Asked Questions
What happens if I miss the 83(b) election deadline?
Nothing can be done to fix it. There is no extension, no late-filing relief, and no procedure for asking the IRS to accept it after 30 days. You fall back to the default rule, which taxes each vesting tranche as ordinary income at that date's value. The only remaining planning is around when you sell and how you manage the resulting bracket pressure.
Can I file an 83(b) election on RSUs?
No. An RSU is an unfunded promise to deliver shares later, not a present transfer of property, and Section 83 applies to property transferred in connection with services. With no property there is nothing to elect on. Filing anyway accomplishes nothing. The election applies to restricted stock awards and to shares acquired by early-exercising options before vesting.
How much tax do I actually pay when I file?
You pay ordinary income tax on the value of the shares at grant, less anything you paid for them. For a founder whose shares are worth fractions of a cent, that can be a few dollars. For an employee early-exercising at a company with a real valuation, the spread between strike price and current value can produce a meaningful bill, which is why the size of the grant drives the decision.
Does an 83(b) election start the long-term capital gain holding period?
Yes, that is a large part of the point. Filing generally starts the holding period at grant or exercise rather than at each vesting date, so shares held long enough after that point can qualify for long-term capital gain rates on the appreciation. Without the election, the holding period for each tranche generally begins when that tranche vests.
Should I file if I am not sure I will stay at the company?
That uncertainty is exactly the reason to run the numbers rather than follow a rule of thumb. If you leave before vesting and forfeit shares, the prepaid tax is not recoverable. When the upfront tax is trivial, the risk is small. When it is a five-figure check, your conviction in the company and your tolerance for losing that cash should drive the answer, ideally with a tax professional involved.
Understanding the 83(b) election deadline is not the same as knowing whether filing is right for your grant, and the two questions get collapsed constantly. If you hold restricted stock, or you are weighing an early exercise, the useful question this week is short: is my clock already running? Schedule a Fit Call and we will look at what you hold and what the numbers actually say.
