A Section 83(b) election is one of the most powerful and most commonly overlooked tax planning tools available to employees who receive restricted stock as part of their compensation. By filing this election within 30 days of receiving the stock grant, an employee chooses to pay income tax on the shares at their current fair market value rather than waiting until the shares vest. When the stock appreciates significantly between the grant date and the vesting date, the tax savings can be substantial.
Understanding how the Section 83(b) election works, when it makes sense to file one, and what risks are involved is essential for anyone receiving equity compensation. This guide breaks down the mechanics, benefits, and potential downsides so you can make an informed decision about your restricted stock tax strategy. The key question it answers is simple: should you file a Section 83(b) election, and when?
How the Section 83(b) election works
Under normal tax rules, restricted stock is not included in an employee’s gross income until it vests. Vesting typically occurs over several years based on a schedule set by the employer. At the point of vesting, the employee owes ordinary income tax on the fair market value of the shares at that time, not the value when they were originally granted.
A Section 83(b) election changes this default treatment. When an employee files the election, they are telling the IRS that they want to recognize the income now, at the stock’s current value, rather than later when it vests. The employee pays ordinary income tax on the fair market value of the stock at the time of the grant, even though they do not yet have full ownership rights. This rule is set out in Internal Revenue Code Section 83 and the related Treasury regulations.
The critical deadline is 30 days from the date the restricted stock is transferred to the employee. If the employee does not file the Section 83(b) election within that 30-day window, the election is invalid and cannot be made later. There are no extensions and no exceptions. The filing must be sent to the IRS, and the employee should also provide a copy to their employer and retain one for their own records.
In November 2024, the IRS released Form 15620, Section 83(b) Election, the first standardized form for making this election. Use of the form is voluntary, so a properly worded written statement still works, but the form lays out exactly what information the IRS expects. Reviewing it before filing is a sensible first step. Because the election is a formal tax position, coordinating it with your broader plan through professional tax advisory services helps avoid procedural errors.
When a Section 83(b) election saves you money
The primary benefit of making a Section 83(b) election is straightforward. If the stock increases in value between the grant date and the vesting date, the employee pays tax on a lower amount. All the appreciation that occurs after the election is not taxed as ordinary income. Instead, when the employee eventually sells the stock, that growth is taxed at the long-term capital gains rate, which is significantly lower than ordinary income tax rates for most taxpayers.
Consider this example. An employee receives 10,000 shares of restricted stock valued at $1 per share, with a four-year vesting schedule. If the employee files a Section 83(b) election, they pay ordinary income tax on $10,000 at the time of the grant. Four years later, when the stock has risen to $10 per share and fully vests, the employee owes no additional ordinary income tax at vesting. If they then sell the shares, the $90,000 in appreciation, equal to $100,000 minus $10,000, is taxed at the capital gains rate.
Without the election, the employee would owe ordinary income tax on $100,000 at vesting, the full fair market value of the shares at that time. The difference in tax liability between these two scenarios can be tens of thousands of dollars. This is the core reason employees with restricted stock tax obligations should carefully evaluate whether to file.
A Section 83(b) election is most beneficial when the stock’s current value is low relative to its expected future value. Early-stage startup employees often find this election especially attractive because the stock price at the time of grant may be a fraction of a penny, meaning the upfront tax cost is negligible.
Factors to evaluate before filing
Making a Section 83(b) election is not always the right decision. Several factors should be weighed carefully before filing.
Current versus future tax rates
The employee must consider whether their marginal tax rate will be higher in the year they receive the stock or in the year the stock vests. If the employee expects to be in a higher tax bracket at the time of vesting, perhaps because of salary increases, bonuses, or other income sources, filing the election early at a lower rate makes sense. If instead the employee expects lower income in future years, waiting may result in a smaller tax bill overall.
Confidence in stock appreciation
An employee should only file a Section 83(b) election if they have reasonable confidence that the stock will increase in value. The election essentially accelerates tax liability based on a bet that the shares will be worth more later. If the stock price stays flat or declines, the employee will have paid taxes earlier than necessary without receiving any offsetting benefit.
Liquidity and cash flow
Filing the election means paying tax now, before the stock has vested and before the employee can sell the shares. Employees need to ensure they have the cash available to cover the tax bill at the time of filing. For employees at early-stage companies where the grant value is low, this is usually manageable. For employees at later-stage companies where shares may already carry significant value, the upfront cash requirement can be a real barrier.
Risks and downsides of a Section 83(b) election
While the upside of a Section 83(b) election can be significant, the risks are real and should not be dismissed.
Stock value decreases after filing
If the stock drops in value after the employee files the election, they will have overpaid on taxes. The employee recognized income at a higher value than the stock is ultimately worth at vesting, and the IRS does not allow a deduction for this difference. The employee cannot claim a loss deduction to offset the tax already paid on the higher grant-date value.
Forfeiture if employment ends before vesting
The most painful scenario occurs when an employee leaves the company, whether voluntarily or involuntarily, before the restricted stock fully vests. In this case, the unvested shares are forfeited. The employee loses the stock but does not get a refund of the taxes paid on it through the Section 83(b) election. The money paid to the IRS is gone, and the employee has nothing to show for it. This risk is particularly relevant for employees at startups and high-growth companies where turnover can be high.
The election is irrevocable
Once a Section 83(b) election is filed, it cannot be revoked without IRS consent, which is rarely granted. The employee is locked into the decision regardless of how circumstances change. This makes it essential to think through all possible outcomes before filing.
How to file a Section 83(b) election
Filing the election requires sending a written statement, or the official Form 15620, to the IRS within 30 days of the stock transfer. The statement must include the employee’s name, address, and taxpayer identification number, a description of the property, the date it was transferred, the taxable year of the transfer, the fair market value of the property at the time of transfer, the amount paid for the property, and a statement that copies have been provided to any other relevant parties.
The filing goes to the IRS Service Center where the employee files their federal income tax return. The employee should send a paper filing by certified mail to have proof of the submission date. As of 2025, the IRS also accepts Form 15620 electronically through its website. A copy of the election should be retained with the employee’s tax records for the year the property was received, and the employee is required to give a copy to the company for whom the services were performed.
Missing the 30-day deadline is one of the most common and costly mistakes in restricted stock tax planning. There is no relief or workaround if the deadline is missed. Setting a calendar reminder immediately upon receiving a stock grant is a simple step that can prevent a significant financial loss. For founders and growing businesses managing equity grants across a team, structured accounting services can keep these filings on track.
Section 83(b) elections and different types of equity
Not all equity compensation is eligible for a Section 83(b) election. The election applies specifically to property, including restricted stock, that is subject to a substantial risk of forfeiture. It does not apply to stock options that have not yet been exercised. If an employee exercises stock options early, before vesting, the resulting shares may be eligible for the election.
Restricted stock units, or RSUs, are generally not eligible for Section 83(b) elections because RSUs are a promise to deliver shares in the future rather than an actual transfer of property. The employee does not own the shares until they vest, so there is no property to elect on at the time of grant. This is an important distinction that employees receiving RSUs should understand.
Founders and early employees who receive restricted stock in exchange for services to a startup are among the most common filers of Section 83(b) elections. The grant-date value of founder shares is typically very low, making the upfront tax cost minimal and the potential upside considerable.
Frequently Asked Questions
What is a Section 83(b) election?
A Section 83(b) election is a filing with the IRS that allows an employee to pay income tax on restricted stock at the time it is granted rather than when it vests. This can result in significant tax savings if the stock increases in value between the grant date and the vesting date.
What is the deadline to file a Section 83(b) election?
The election must be filed within 30 days of the date the restricted stock is transferred to the employee. This deadline is strict. There are no extensions, and missing it means the election cannot be made for that stock grant.
Can you lose money by filing a Section 83(b) election?
Yes. If the stock decreases in value after filing, the employee will have paid tax on a higher amount than the stock is ultimately worth. Additionally, if the employee leaves the company before the stock vests, the shares are forfeited but the taxes already paid are not refunded.
Do RSUs qualify for a Section 83(b) election?
No. Restricted stock units are a promise to deliver shares in the future and do not involve an actual transfer of property at the time of grant. Because no property changes hands, there is nothing to elect on under Section 83(b).
Who benefits most from a Section 83(b) election?
Early-stage startup employees and founders who receive restricted stock at a very low valuation benefit the most. The upfront tax cost is minimal, and if the company grows significantly, the appreciation is taxed at the lower capital gains rate instead of ordinary income rates.
Should I consult a tax advisor before filing a Section 83(b) election?
Yes. The decision involves evaluating your current tax bracket, expected stock appreciation, vesting schedule, employment stability, and cash flow. A qualified tax advisor can model the scenarios and help you determine whether filing is the right choice for your specific situation.
