What Is an 83(b) Election?
A powerful IRS election that can save early employees hundreds of thousands in taxes. Here's how it works in plain English.
83(b) = pay taxes on your stock NOW (low value) instead of later (high value).
You have 30 days from your grant date to file. Miss it = no do-overs.
The Math That Changes Everything
WITHOUT 83(b)
You get 50,000 shares at $0.10 each
Company exits at $50/share
WITH 83(b)
Tax now on $5,000 value (50k x $0.10)
Company exits at $50/share
Your savings with 83(b)
$661,000
That's 52% less in taxes
File Early = Pay Less
Earlier filing = lower stock value = less tax now. Most successful filers act within the first week.
The Risk-Reward Tradeoff
The Risk
Leave early or company fails = you paid tax on shares you'll never own. The IRS allows no deduction — that tax is gone.
The Reward
Company succeeds = pay 23.8% instead of 50%+. Save $100K-$500K.
