Introduction

If you receive stock, equity, or other property in exchange for services—especially in startups or closely held businesses—you may have heard about the “83(b) election.” This obscure tax filing can dramatically change how and when you are taxed.

But here’s the problem:
Most taxpayers either miss the deadline or don’t understand the risk.

This article breaks down Internal Revenue Code § 83(b), the governing Treasury Regulations, and the real-world consequences—good and bad—of making this election.

The Default Rule: Taxation of Property for Services

Under IRC § 83(a), property transferred in connection with services is taxed when it becomes vested:

“The excess of the fair market value of such property… over the amount (if any) paid for such property shall be included in the gross income of the person who performed such services…”
— IRC § 83(a)

Critically, this applies when the property is no longer subject to a substantial risk of forfeiture.

Treasury Regulation Clarification

The regulations define this timing clearly:

“Property is includible in gross income… when it is either transferable or not subject to a substantial risk of forfeiture.”
— Treas. Reg. § 1.83-1(a)

What Is an § 83(b) Election?

Section 83(b) allows you to accelerate taxation to the time of transfer—even if the property is not yet vested.

“If a person who performs services… elects to include in gross income… the excess of the fair market value of the property at the time of transfer… then subsection (a) shall not apply…”
— IRC § 83(b)(1)

In plain English:
You choose to pay tax now instead of later.

Why Would Anyone Do This?

Because early-stage equity is often worth very little at grant—but potentially much more later.

Example

• You receive founder shares worth $1,000 today
• They vest over 4 years
• After vesting, they’re worth $500,000

Without § 83(b):

• You pay ordinary income tax on $500,000

With § 83(b):

• You pay tax on $1,000 today
• Future growth is taxed as capital gains

The Strict 30-Day Deadline

This is where most people mess up.

“An election… must be filed… not later than 30 days after the date of transfer of the property.”
— Treas. Reg. § 1.83-2(c)

There are no extensions. No exceptions for ignorance. No equitable relief in most cases.

Miss it, and you’re stuck with default treatment.

The Major Risk: You Might Pay Tax on Something You Lose

The downside is real.

If you make an 83(b) election and then:

• Leave the company
• Forfeit unvested shares
• The company fails

You do not get your tax back.

The Code is explicit:

“No deduction shall be allowed… for the amount previously included in gross income.”
— IRC § 83(b)(1)

When an 83(b) Election Makes Sense

Generally favorable when:

• The current value is very low
• The upside potential is high
• The risk of forfeiture is low to moderate
• You can afford the upfront tax

When It Does NOT Make Sense

Be cautious when:

• The valuation is already high
• The company is unstable
• You’re unsure you’ll stay long enough to vest
• You lack liquidity to pay the tax

Practical Filing Requirements

To be valid, the election must:

• Be filed with the IRS within 30 days
• Include:
  • Taxpayer information
  • Description of property
  • Date of transfer
  • Fair market value
  • Amount paid
• Be sent to the appropriate IRS service center

Failure to comply strictly can invalidate the election.

Common Mistakes

1. Missing the 30-day deadline
2. Using incorrect valuation
3. Forgetting to mail (certified is best practice)
4. Assuming RSUs qualify (they generally do not until settled)
5. Not coordinating with legal and tax advisors

Final Thoughts

The § 83(b) election is one of the most powerful—and dangerous—tools in the tax code for equity compensation.

Handled correctly, it can convert ordinary income into long-term capital gain.
Handled poorly, it can create a tax bill on wealth that never materializes.

As with most tax strategies:
Timing, documentation, and risk tolerance matter more than the rule itself.
