Meaning
An election under the United States tax code allows an employee or founder to pay income tax on the fair market value of restricted stock at the grant date rather than when it vests. This filing under section 83(b) must be submitted to the Internal Revenue Service within thirty days of the stock transfer. It converts future appreciation of the stock from high-rate ordinary income into lower-rate long-term capital gains when the shares are eventually sold.
The election protects the shareholder from a massive tax bill in the future if the company’s valuation rises before the shares vest.
Filing Deadline
The thirty-day submission window is absolute and cannot be extended for any reason, making it one of the most time-sensitive steps in the startup incorporation process. Founders must send the election via certified mail to prove the filing date. A copy of the form must also be provided to the employer.
Tax Exposure
By making the election, the shareholder pays tax on the current value of the stock, which is often negligible at the time of company formation. If the election is not filed, the taxpayer faces ordinary income tax on the value of each tranche of stock as it vests in the future. This difference can lead to substantial tax liability on illiquid shares if the startup’s valuation has increased.
In extreme scenarios, the employee could be forced to sell other assets to pay taxes on vesting stock that cannot be traded on any public exchange.
Forfeiture Risk
The primary risk of this election is that the taxpayer pays taxes on stock that may later be forfeited or decline in value. If the employee leaves the company before the restricted stock vests, the shares are returned, but the taxes paid at the grant date cannot be recovered. This risk is usually acceptable to founders because the initial stock value is extremely low.
