Making an IRS Section 83B election

While speaking to a friend that is starting a company I realized that I haven’t written about filing an 83b Election. The election is a very important step in new company formation and if forgotten can have painful tax consequences.

I use stock vesting to refer to both traditional options vesting agreements and the buy-back restrictions on granted stock. In practice the two approaches generally serve the same purpose: to grant stock rights to an employee over time.

What is an IRS Section 83B Election?

The Section 83B election allows employees to change the tax treatment of a restricted stock grant. Normally, employees pay regular income tax when the stock vests (the restrictions lapse) and no tax when the restricted stock is granted.

The 83B election allows employees to pay income tax on the initial grant instead of paying tax when the stock vests. More specifically, they pay tax on the difference between the amount they paid and the Fair Market Value (FMV) of the stock.

Since the FMV of a brand new enterprise is generally close to zero, most founders purchase their stock at FMV. If the founders file an 83B, they end up paying no tax at purchase and no tax when the stock vests. They will only need to pay capital gains tax when the stock is sold.

The 83B election only applies to restricted stock – it only deals with the recognition of income on stock that has restrictions that lapse.

Let’s use an example to illustrate the effect of making (or not making) the election. We’ll consider a founder that is subject to a 4 year annual vesting schedule:


At formation, the company stock is determined to have a FMV of $0.001 per share and he is granted 100,000 shares. The firm grows and the FMV increases to $.10 in Y1, $1.00 in Y2, $10 in Y3, $100 in Y4 (nice growth curve). Assume a 40% regular income tax.

Initial Stock Purchase: $100
Value of stock that vests in Y1: $2,500
Value of stock that vests in Y2: $25,000
Value of stock that vests in Y3: $250,000
Value of stock that vests in Y4: $2,500,000

83b election filed
Taxes Due at Purchase: $0
Taxes Due at Vesting Intervals: $0
At the end of the 4 years, the founder owns all of his stock outright and has paid no taxes on it. Should he sell the stock, he would be subject to long-term capital gains taxes.

No election made
Taxes Due at Purchase: $0
Taxes Due at Vesting Intervals: Y1: $1000, Y2: $10,000, Y3: $100,000, Y4: $1,000,000
Total taxes paid: $1,111,000

And these taxes had to be paid before the company ever had a liquidating event (the founder never received cash for his stock).

Even worse, if the company collapses in Y5 the founder will have paid over $1M in taxes and never received any cash for his stock.

When do you need to make an 83B Election?

Within 30 days of assuming stock ownership. This rule is notoriously inflexible. The election form must be sent to the IRS within 30 days of the grant.

83B applied to startups

The 83B is typically relevant in two scenarios:

  1. Restricted stock agreements for founders. The most common scenario is the restricted stock agreements of founders. Founders should usually draft and sign restricted stock agreements at the same time that they purchase their initial shares.

    A common scenario is one where founders don’t draft vesting agreements when they form the company. Some time later, the company takes investment and the investors require that the founders accept restrictions on their existing stock.
    Since the stock in question was granted more than 30-days ago, filing an 83b might not be an option.

    I’ve received distinctly opposing views from lawyers on this scenario, and a recent ruling (Revenue Ruling 2007-49) by the IRS provides some, but not necessarily full guidance.

    Creating stock vesting agreements after the 30-day 83B window is tricky and can require new stock grants that dilute the initial holdings. Altering existing vesting agreements is much more straightforward and is directly addressed by the IRS ruling mentioned above (and typically allows the original 83b filing to remain in effect).

    In my opinion, founders should always draft vesting agreements when the company is incorporated (for a multitude of reasons). This has an important benefit of giving them the opportunity to file their 83b election within the 30-day window. This significantly lowers the risk that they find themselves owing tax as shares vest if they are required to accept vesting agreements in the future.

  2. Early option exercise plans. Some option plans allow employees to exercise their options prior to vesting. This provides the employees the tax advantage of starting the clock on long-term capital gains early. Once the options are exercised, they typically become subject to a stock restriction agreement and the employees would need to file an 83B after they exercise.

How to make an 83B election
The IRS doesn’t provide a form for the 83B election, but the process is straightforward. From IRS publication 525:


How to make the choice. You make the choice by filing a written statement with the Internal Revenue Service Center where you file your return. You must file this statement no later than 30 days after the date the property was transferred. A copy of the statement must be attached to your tax return for the year the property was transferred. You also must give a copy of this statement to the person for whom you performed the services and, if someone other than you received the property, to that person.

You must sign the statement and indicate on it that you are making the choice under section 83(b) of the Internal Revenue Code. The statement must contain all of the following information.

  • Your name, address, and taxpayer identification number.
  • A description of each property for which you are making the choice.
  • The date or dates on which the property was transferred and the tax year for which you are making the choice.
  • The nature of any restrictions on the property.
  • The fair market value at the time of transfer (ignoring restrictions except those that will never lapse) of each property for which you are making the choice.
  • Any amount that you paid for the property.
  • A statement that you have provided copies to the appropriate persons.

The form we used to file our 83B elections at BrandVerity is here. Most lawyers will recommend that this notice be sent via certified mail.

An important building block for understanding startup stock options is understanding the differences between Incentive Stock Options (ISOs) and NonIncentive Stock Options (NSOs). This post looks at the tax implications of both types of options as well as the situations when you might receive (or use) one or the other.
