What Is a Section 83(b) Election?

A Section 83(b) election is a letter you send to the IRS within 30 days of receiving restricted stock or equity that hasn’t vested yet. It tells the IRS you want to pay all your ordinary income taxes on the shares right now based on their current value, instead of waiting to pay taxes as the shares vest in the future.

1. Meaning of “Section 83(b) Election”

In plain English, a Section 83(b) election is like “pre-paying” your taxes to lock in a lower bill. Normally, the IRS waits until your stock “vests” (becomes truly yours to keep) before they tax you. By filing this election, you are choosing to be taxed on the grant date instead of the vesting date.

Why would anyone want to pay taxes early? Because if you expect the stock price to go up significantly, paying taxes while the price is very low can save you a fortune later. It also “starts the clock” for long-term capital gains, which are taxed at a lower rate than regular income.

2. Why “Section 83(b) Election” Matters

Taxpayers should care about this term because it is a powerful wealth-building tool, but it comes with a “drop-dead” deadline. If you miss the 30-day window to file, you lose the option entirely. For startup founders or early employees, this election can mean the difference between paying a few hundred dollars in taxes today versus hundreds of thousands of dollars in taxes a few years from now.

3. How “Section 83(b) Election” Works

The process is manual and requires a bit of old-school effort. Once you are granted restricted stock, you have exactly 30 days to mail a physical letter to the IRS. In this letter, you provide details about the stock you received and its current fair market value.

Once filed, you report the value of that stock as income on your tax return for that year. From that point on, the IRS ignores the vesting schedule for tax purposes. When you eventually sell the shares years later, the entire growth from the day you received them is treated as a capital gain, rather than regular salary.

4. Simple Example of “Section 83(b) Election”

Imagine you are a founder and receive 100,000 shares worth $0.01 each ($1,000 total). You file an 83(b) election and pay ordinary income tax on that $1,000 immediately.

Four years later, the shares vest, and the price has jumped to $10.00 each.

With an 83(b) election: You owe $0 in taxes when they vest. You already paid your dues at the $0.01 price.
Without an 83(b) election: You would owe ordinary income tax on $1,000,000 the moment they vest, even if you don’t sell the shares for cash.

5. Who Is Affected by “Section 83(b) Election”?

Startup Founders: Almost always filed when a company is first formed and stock is worth nearly zero.
Early Employees: Those receiving restricted stock awards (RSA) as part of their hiring package.
Investors: Specifically those who receive stock that is subject to a “reverse vesting” schedule.

Note: This generally does not apply to Restricted Stock Units (RSUs), as the IRS rules for RSUs are different.

6. Common Mistakes Related to “Section 83(b) Election”

Missing the 30-day deadline: There are no extensions and no “do-overs.” If you are on day 31, you are too late.
Not using Certified Mail: If the IRS loses your letter and you can’t prove you sent it, they will assume you never filed. Always get a postmarked receipt.
Forgetting to give a copy to your employer: Your company needs a copy so they can accurately report your income on your W-2.
Filing for RSUs: Many people try to file an 83(b) for RSUs, but it typically doesn’t work and provides no benefit because you don’t legally “own” the units yet.

7. Forms Related to “Section 83(b) Election”

Interestingly, there is no official, numbered IRS “form” like a 1040. Instead, it is a written statement that must contain specific information required by the IRS. You can find templates online or through your company’s lawyers. You mail this statement to the same IRS office where you file your individual tax return.

8. “Section 83(b) Election” vs. Related Terms

83(b) vs. Standard Vesting (83(a)): Standard rules (83(a)) tax you as you vest at the future price. 83(b) taxes you once at the start at the current price.
83(b) vs. 83(i): 83(i) is a newer, rarer election for private company employees to defer taxes, while 83(b) is about paying immediately.

10. FAQs About “Section 83(b) Election”

Can I undo an 83(b) election?
No. Once filed, it is almost impossible to revoke. You are committed to that tax path.

What if the stock price goes down or the company fails?
This is the risk. If you pay taxes upfront and the stock becomes worthless, you cannot get a refund from the IRS for the taxes you already paid.

Do I have to file it every year?
No. You file it once for each specific grant or purchase of restricted stock within the 30-day window of receiving it.

Is an 83(b) election only for startups?
While most common in startups, it can be used for any stock grant that is “subject to a substantial risk of forfeiture” (meaning it hasn’t vested yet).

11. Final Takeaway

A Section 83(b) election is a gamble that pays off if your company grows. By choosing to pay a small amount of tax today on a low stock value, you protect yourself from a massive tax bill in the future. It turns your hard work into an investment rather than just a salary. Just remember the golden rule: mark your calendar, check it twice, and get that letter in the mail before the 30-day clock runs out.
