Section 83(b) Election: Pay Tax Early on Equity

Key Takeaways

• A Section 83(b) election taxes restricted stock at grant value, not at the higher vesting value.
• You must file within 30 calendar days of the grant, a deadline the IRS will not extend.
• The main risk is paying tax on stock that later becomes worthless, with no refund.
• It starts the capital gains holding period at grant, helping future gains qualify for long-term rates.

What a Section 83(b) Election Is

Under Internal Revenue Code section 83, when you receive stock for your services that is still subject to vesting, the default rule taxes you as the stock vests. You owe ordinary income tax on the difference between the value at vesting and what you paid. If the stock climbs while it vests, your taxable income climbs with it.

A Section 83(b) election flips the timing. You elect to be taxed at grant on the spread between the grant value and your purchase price. For founders who buy stock at a nominal price when the company is worth almost nothing, that spread is often zero or close to it.

The Intuition

The election makes sense when you expect the stock to rise a lot before it fully vests. Paying a small tax now, while the value is low, can be far cheaper than paying ordinary income tax later on a much larger spread.

It also changes the character of future gains. Once you have included the value in income, later appreciation is a capital gain rather than ordinary compensation income. Holding the shares long enough can make that gain long-term, taxed at lower rates.

How It Works

The mechanics are simple but unforgiving on timing. You sign the election and file it with the IRS within 30 calendar days of the grant date. The clock starts the day of transfer and cannot be extended for any reason. Courts have rejected late filings.

Default (no 83(b)):  tax at vesting on (value at vesting - price paid)
With 83(b):          tax at grant on (value at grant - price paid)

You also send a copy to your company and keep one for your records. The election starts your capital gains holding period at the grant date. If you later forfeit the unvested stock, you get no deduction for the tax you already paid, which is the central downside.

Worked Example

Suppose a founder buys 1,000,000 shares of restricted stock at 0.001 dollars each, a total of 1,000 dollars, when the fair value equals the price. The stock vests over 4 years and rises to 5.00 dollars per share by full vesting.

With 83(b) at grant:
  Spread at grant = (0.001 - 0.001) x 1,000,000 = 0 ordinary income now
  Future gain when sold is capital gain

Without 83(b), taxed at vesting:
  Spread = (5.00 - 0.001) x 1,000,000 = ~4,999,000 ordinary income

By filing the 83(b), the founder reports essentially no income now and converts roughly 5 million dollars of future value into capital gain rather than ordinary income. The election cost almost nothing because grant value equaled the purchase price.

Common Mistakes

1. Missing the 30-day deadline. This is the most common and most costly error. The window is strict, and there is no late-filing relief.

2. Filing when the spread is large. If grant value far exceeds what you pay, the election creates a real tax bill now. The benefit shrinks when there is little appreciation left to defer.

3. Electing on stock that may be forfeited. If you leave before vesting and forfeit the shares, the tax you prepaid is gone. There is no refund or deduction.

4. Forgetting to keep proof of filing. A paper election is treated as filed when mailed, so certified mail with a receipt protects you if the IRS questions timing.

5. Confusing 83(b) with vesting itself. The election does not change the vesting schedule or your service obligation. You still must vest to keep the shares.

Frequently Asked Questions

What is a Section 83(b) election in simple terms? A Section 83(b) election tells the IRS you want to pay tax on restricted stock now, at its low grant value, rather than later when it vests at a higher value. You file it within 30 days of getting the stock.

How does a Section 83(b) election affect investment decisions? It is most valuable when you expect the stock to appreciate sharply before vesting, because it locks in a small tax bill and converts future gains to capital gains. Employees weigh that benefit against the risk of paying tax on stock that might never pay off.

What is a real-world example of a Section 83(b) election? A founder buys 1,000,000 shares at 0.001 dollars each when value equals price, files an 83(b), and reports zero income now. Future appreciation to 5.00 dollars per share is taxed as capital gain instead of ordinary income.

How can investors use a Section 83(b) election effectively? File within 30 days, use certified mail, and elect mainly when the grant spread is small and you are confident in the company. Confirm your vesting terms so you understand the forfeiture risk.

How is a Section 83(b) election different from a Section 83(i) deferral? An 83(b) election accelerates tax to the grant date to capture low value, while an 83(i) deferral postpones tax on private company equity for up to 5 years. One pays early on purpose, the other delays.
