83(b) Election Explained: What It Is, Pros, Cons and How to File

A timely and correctly filed 83(b) election can lead to significant tax savings, especially for early-stage companies where the value of shares is expected to appreciate substantially over time. The election allows you to pay taxes on restricted stock — including shares from early-exercised stock options — at the time of grant or early exercise rather than waiting until vesting, which could result in a lower tax liability if the value increases significantly.

What Is an 83(b) Election?

A Section 83(b) election is a written election filed with the Internal Revenue Service that allows a taxpayer to include the value of transferred restricted property — the fair market value (FMV) of the restricted stock, less any amount paid for it — in income at the time of transfer rather than at vest.

By electing this treatment, you include income on unvested shares before you have full ownership — typically when the spread between what you paid and the FMV is small or zero. A section 83(b) election may also begin the holding period for the transferred shares at grant or early exercise rather than vesting, which can help you meet applicable long-term capital gain holding-period requirements sooner.

One important thing to note is that a stock option itself can’t be 83(b)-elected. For stock options, the election only comes into play once you early exercise and convert the option into actual shares that are subject to vesting. It’s those restricted shares, not the option, that you elect on.

For example, say you early exercise 10,000 stock options with a $0.50 exercise price at a moment when the FMV is also $0.50 per share:

With an 83(b) election – The spread is $0, so you recognize essentially no ordinary income today — and nothing further as the shares vest. Sell three years later at $5.00, and your $45,000 of growth may receive long-term capital gains treatment, assuming the applicable holding-period requirement and other requirements are met.

Without an 83(b) election – If the FMV is $3.00 at vesting, you recognize $25,000 of ordinary income ($3.00 - $0.50 × 10,000 shares) on shares you haven’t sold, and only growth above $3.00 is eligible for capital gains treatment.

This contrast illustrates why an 83(b) election may be attractive when the spread is low and the shares are expected to appreciate: it may move more future appreciation into capital gains treatment and avoid additional ordinary income tax as the shares vest.

How an 83(b) Election Applies by Equity Type: NSOs, ISOs and RSAs

The mechanics — and whether an 83(b) election is even available — depend on the type of equity award you hold. (For background on how stock options differ from restricted stock units, see our separate guide.)

Non-qualified stock options (NSOs)

NSOs without early exercise or 83(b) election

At the time of grant, there’s no tax implication. When the options vest and you exercise, the spread (the difference between FMV at exercise and the exercise price) is taxed as ordinary income and subject to withholding. If you sell shares at a gain later, the difference between the sale price and FMV at exercise is taxed as a capital gain — short-term or long-term depending on the holding period.

NSOs with early exercise and an 83(b) election

If you early exercise your nonqualified stock options before they vest, you can file an 83(b) election to be taxed on the spread between the exercise price and FMV at exercise. Doing so can result in little to no taxable income if the exercise price and FMV are similar. After filing the 83(b) election, there’s no additional tax at vesting, because you already paid tax at exercise. When you sell the shares at a gain after holding them for at least a year, long-term capital gains rates may apply to the difference between the sale price and the FMV on the exercise date, assuming the applicable holding period requirement and other requirements are met.

Who should consider this option? NSO holders who typically benefit are employees at early-stage companies who are confident the stock will appreciate, plan to stay through vesting and can comfortably afford the exercise cost.

When should you not file an 83(b) election for NSOs?

You shouldn’t file an 83(b) election for NSOs when there’s:

• Risk of forfeiture – If you may leave the company before the shares vest, you could lose the tax benefits and only get a limited tax deduction based on your cost.
• Risk of loss – If the stock’s value decreases, you won’t be able to claim the loss until you sell, and it will be subject to capital loss limitations.
• A large upfront tax bill – If you need to borrow money to exercise early for tax benefits, it might not be worth the financial strain.

Incentive stock options (ISOs)

ISOs already defer regular income tax until sale, provided you meet the holding period requirements (two years from grant, one year from exercise). The catch is that the spread at exercise counts toward the alternative minimum tax (AMT). Early exercising an incentive stock option and filing an 83(b) election accelerates that AMT adjustment to a point when the spread is small, potentially reducing AMT exposure.

Who should consider this option? This tends to suit option holders who expect a large spread — and therefore a meaningful AMT bill — if they wait to exercise at vesting. If you’re unlikely to trigger AMT, the election may offer little benefit.

Restricted stock awards (RSAs)

RSAs without an 83(b) election

If you receive RSAs as part of your compensation, there’s no tax due at grant. At vesting, the spread (FMV on vesting minus purchase price) is taxable as ordinary income and subject to withholding, and your cost basis in the shares is the FMV on the vesting date. When you sell, the growth from the vesting price to the sale price is eligible for long-term capital gains treatment if the shares are held for at least a year after vesting and the other applicable requirements are met.

RSAs with an 83(b) election

If you file an 83(b) election within 30 days of the RSA grant, you pay tax on the spread at the time of the grant. This amount is treated as ordinary income and subject to withholding. The cost basis becomes the FMV on the grant date, and no additional tax is due at vesting. When you sell the shares, any gain from the FMV at grant to the sale price is taxed as a long-term capital gain after holding for a year, assuming the applicable holding-period requirement and other requirements are met.

Who should consider this option? Filing an 83(b) election for RSAs may be beneficial if you anticipate the shares could potentially appreciate, and you plan to stay with the company until vesting. If there’s a high risk of forfeiture or decline in value, or if the upfront tax payment is a burden, it might be better to avoid filing.

Risks of Filing an 83(b) Election

An 83(b) election can be beneficial, but it also carries significant risks, such as:

• Forfeiture of shares – If the shares are forfeited — for example, if you leave the company before vesting — your deduction is limited to the amount you actually paid for the shares (i.e., your cost basis), not the ordinary income you previously recognized. The taxes paid at the time of the 83(b) election can’t be recovered.
• Price risk – If you ultimately sell the shares for less than your cost basis, the loss is a capital loss, which can only offset capital gains plus up to $3,000 of ordinary income per year (if single or married filing jointly). You may have prepaid tax on value that never materializes.
• Liquidity risk – Private company shares generally can’t be sold to cover the upfront tax bill or exercise cost. If you’d need to borrow to fund an early exercise, the strategy may not be worth the financial strain.
• Filing risk – The election is only valid if it’s filed correctly and on time. Miss the 30-day window or make an error, and the default tax treatment applies.

How and When to File: The 30-Day Deadline, Form 15620 and the 2025 Mailing Rule Change

The single most important rule is timing. The election generally must be filed within 30 days after the transfer of the restricted property — typically the grant date for restricted stock, or the early-exercise date when options are converted into unvested shares. Because this is a short statutory filing period, act promptly and confirm the applicable deadline with a qualified tax professional; special timing rules may apply when the final day falls on a weekend or legal holiday.

There are two ways to file:

Paper filing – Mail the election to the IRS office where you file your tax return. Best practice is to send it via certified mail with return receipt and include a copy with a self-addressed stamped envelope so that the IRS can return a date-stamped copy for your records.

Electronic filing with Form 15620 – The IRS now allows taxpayers to complete and submit Form 15620, the standardized 83(b) election form, online through its website using an IRS online account. E-filing provides an electronic confirmation of submission and a downloadable copy of the filed form rather than leaving you to wonder whether your election arrived in the mail.

Use one method only, not both.

A recent change makes the electronic route even more attractive. Effective December 24, 2025, under a new USPS rule, mail is postmarked when it’s processed at a postal facility, not when you drop it in a mailbox. A paper election deposited close to day 30 could receive a postmark after the deadline and be invalid. If you must file on paper near the deadline, get a hand-stamped postmark at a retail counter; otherwise, e-filing this IRS form is the safer option.

Whichever route you choose, you’re still required to provide a copy of the filed election to your employer (or the company issuing the shares) so that it can report and withhold correctly. You’ll also want to keep a copy for your own records.

How Does This Affect Qualified Small Business Stock?

For startup founders and early employees, an 83(b) election can carry a second, less obvious benefit: it can start the qualified small business stock (QSBS) holding-period clock. Under the Section 1202 QSBS exclusion, eligible shareholders may be able to exclude some or all of their eligible federal gain, subject to Section 1202 requirements and applicable limitations. Because an 83(b) election can move your acquisition date to grant or early exercise rather than vesting, it can start that clock years earlier in some cases.

QSBS treatment isn’t automatic. The stock must meet specific criteria under the Internal Revenue Code, including requirements around the issuing company’s structure, gross assets and active business use, and the exclusion generally requires holding the shares for at least three or five years, depending on the acquisition date. For a founder or early employee at a fast-growing startup, starting this five-year clock at grant rather than at final vest can determine whether an eventual sale qualifies. An 83(b) election is best viewed as one piece of a broader tax planning strategy for qualified small business stock, alongside concentrated stock strategies for managing the position your equity may grow into.

Need Help Implementing an 83(b) Election?

83(b) elections sit at the intersection of equity compensation, tax law and long-term financial planning, which is why they’re particularly relevant for tech professionals, founders and corporate executives receiving restricted stock, early-exercised options and other restricted equity as part of compensation. The decision to file involves judgment calls about your company’s prospects, your career plans and your capacity to pay tax today for a benefit that arrives years from now.

And the decision rarely stands alone. A well-considered election typically sits within a wider set of decisions: whether early exercising makes sense in the first place, how the election interacts with AMT if you hold incentive stock options, whether your shares might qualify for QSBS treatment down the road, and how to fund the exercise cost and any upfront tax without straining your cash flow.

Even the logistics matter, such as meeting the 30-day deadline, choosing between paper filing and Form 15620, providing the required copy to your employer and keeping clean records for the year you eventually sell. And once your equity appreciates, it often becomes the next planning challenge: managing a concentrated company stock position that may represent an outsized share of your net worth.

Frequently Asked Questions About 83(b) Elections

What is an 83(b) election, and how does it work?

An 83(b) election is a written election filed with the IRS that lets you include the value of restricted stock in income at grant or early exercise, when the spread is typically low, rather than at vesting. Future appreciation may then receive capital gains treatment, and the holding period for the shares may begin at that point rather than at vesting.

What are the pros and cons of filing an 83(b) election?

Potential benefits include lower ordinary income at the time of transfer when the spread is small, an earlier holding-period start and the possibility that future appreciation receives capital gains treatment. The outcome depends on the equity award, future value, the holding period and your individual tax situation. The trade-off is paying taxes upfront on shares you could still forfeit or that could lose value, and those taxes generally can’t be recovered.

What’s the deadline for filing an 83(b) election?

Generally, 30 days after the transfer of the restricted property — the grant date for restricted stock awards or the early-exercise date for options. Special timing rules may apply if the final day falls on a weekend or legal holiday, so confirm your deadline with a qualified tax professional. Filing Form 15620 electronically provides an electronic confirmation of submission.

Does an 83(b) election apply to RSUs?

No. Restricted stock units aren’t property under Section 83 at grant — they’re a promise to deliver shares later — so no election is available. RSUs are taxed as ordinary income when shares are delivered at vesting. The election applies only to restricted stock, including shares from early-exercised options.
