The 83(b) election: the 30-day window founders miss

Key Takeaways

• An 83(b) election lets you pay taxes on your stock's current value instead of its future value when it vests.
• You have 30 days from the date you get the stock to file. Miss it and you're done. No extensions. No exceptions.
• For early-stage founders getting stock at fractions of a penny per share, filing an 83(b) can mean a much smaller tax bill later.
• Most people file by mailing a signed election to the IRS, by certified mail so there's proof of the date.
• If your company fails, you can't get the taxes back. For founders getting stock at near-zero value, that tax is usually small.

Why This Matters More Than You Think

Most founders I talk to have never heard of an 83(b) election until someone casually mentions it. And by then, it's sometimes too late.

Here's the situation. You start a company or join one early. You receive restricted stock, meaning shares that vest over time, usually 4 years with a 1-year cliff. Under normal tax rules, you'd pay income tax on those shares as they vest, based on whatever the shares are worth at the time of vesting.

If the company is worth nothing when you get the shares but worth $10 million by year two, you're paying taxes on $10 million worth of stock. Even though you haven't sold anything. Even though you might not be able to sell for years.

The 83(b) election lets you short-circuit that. You pay taxes on the shares right now, at their current value, which for an early-stage startup might be $0.001 per share. Your tax bill could literally be a few dollars instead of hundreds of thousands.

How It Actually Works

Let's say you co-found a company and receive 1,000,000 shares of restricted stock at $0.001 per share. Total value: $1,000.

Without an 83(b): you pay income tax as shares vest. If the company is worth $5 per share when your shares vest over years 1 through 4, you're paying ordinary income tax on $5,000,000 worth of stock. At a 37% federal rate, that's $1,850,000 in taxes. On stock you haven't sold.

With an 83(b): you pay income tax now on the $1,000 value. Your tax bill is roughly $370. When you eventually sell the shares for $5,000,000, the gain is taxed as long-term capital gains (assuming you held for over a year), which maxes out at 20%. That's $999,800 in gains taxed at 20%, or about $199,960.

The difference: $1,850,000 vs $200,330. In this example, that's roughly $1.65 million less in tax.

These numbers are simplified, but the principle is real. IRS Revenue Procedure 2012-29 walks through examples of how the election works.

The 30-day rule

This is where people mess up. You have 30 calendar days from the date you receive your restricted stock to file the 83(b) election with the IRS. Not 30 business days. Calendar days. Including weekends and holidays.

The usual way to file is a signed election mailed to the IRS. You also send a copy to your company and keep one for your records. If you mail it, use certified mail so you have proof of the postmark date.

If you miss the 30-day window, there is no remedy. No late filing. No appeal. It's gone.

Founders miss this because they didn't know about the deadline, or they knew but figured they'd get to it later. Don't be that person.

When You Should Not File an 83(b)

It's not always a slam dunk. There are situations where filing doesn't make sense.

If you're receiving stock that already has significant value and you'd owe a large tax bill upfront, you need to think carefully. Paying $50,000 in taxes today on stock that might be worthless in two years is a real risk.

If you're joining a later-stage company where the stock price is already high, the 83(b) math changes. The gap between current value and future value is smaller, so the tax savings are smaller.

And here's the big one: if the company fails and the stock becomes worthless, you don't get your taxes back. The IRS considers it a capital loss, which you can deduct, but only up to $3,000 per year against ordinary income. If you paid $50,000 in taxes on an 83(b) for stock that went to zero, it takes a long time to recover that through capital loss deductions.

For early-stage founders getting stock at near-zero valuations, though, the tax you pay up front is usually small compared to what you could owe at vesting without it.

Step by Step: How to File

Here's what you need to do:

Write a letter that includes your name, address, Social Security number, the company name, a description of the stock, the date you received it, the fair market value on that date, the amount you paid for it, and a statement that you're making an election under Section 83(b).

Mail the letter to the IRS service center where you file your return, via certified mail with return receipt requested. Keep the green card when it comes back.

Send a copy to your company (they need it for their records).

Attach a copy to your tax return for the year you received the stock.

The whole thing takes about 30 minutes if you know what you're doing. Your accountant or tax advisor can handle it. If you don't have one, this is a good reason to get one.

The Takeaway

The 83(b) election is one of those rare tax strategies that's simple, powerful, and available to anyone who receives restricted stock. The catch is the 30-day deadline and the fact that most people don't know it exists.

If you've recently received restricted stock in a startup, ask your tax advisor about it today. Not next week. Today. Because 30 days goes by faster than you think.

Summary

The 83(b) election lets founders pay taxes on stock at its current low value instead of its potentially much higher future value. You have 30 days from the date you get the stock to file. For early-stage founders, the difference in tax can be large. The risk is that if the company fails, you don't get the taxes back, but for stock valued at fractions of a penny, the downside is tiny. File it, keep proof, and move on to building your company.
