Five events end the deferral, and only one of them is the employee's own choice. Inclusion happens in the taxable year containing the earliest of: the first date the qualified stock becomes transferable, including transferable to the employer; the date the employee first becomes an excluded employee; the first date any stock of the issuing corporation becomes readily tradable on an established securities market; the date five years after the rights first became transferable or ceased to be subject to a substantial risk of forfeiture; or the date the employee revokes the election. A promotion into the corner office, an initial public offering, or an acquisition that makes the shares transferable will all end the deferral early.
The excluded-employee test bars the people most likely to want this. Under 83(i)(3)(B), an excluded employee is anyone who is or has been at any time during the calendar year, or in the 10 preceding calendar years, a 1-percent owner of the corporation within the meaning of section 416(i)(1)(B)(ii), the key employee provision. It also captures anyone who is or has ever been the chief executive officer or chief financial officer, or who acted in either capacity; anyone bearing a family relationship described in section 318(a)(1) to such a person, which reaches spouses, children, grandchildren and parents; and anyone who is one of the four highest compensated officers of the corporation for the taxable year or was for any of the 10 preceding years, determined using the shareholder disclosure rules under the Securities Exchange Act of 1934 as if they applied to a private company. This is a look-back test, so a person who has left an executive role does not become eligible by doing so.
Two further limitations sit in 83(i)(4)(B), and the third is unusual. No election may be made if the employee has already made an 83(b) election on the same stock, or if any stock of the corporation was readily tradable at any time before the election is made. The third is a company-level anti-abuse rule aimed at tender offers: if the corporation purchased any of its own outstanding stock in the calendar year before the year containing the vesting date, no new election may be made unless at least 25 percent of the total dollar amount of stock so purchased was deferral stock, meaning stock already covered by an 83(i) election, and the choice of whose deferral stock was bought was made on a reasonable basis. The requirement is treated as met if the purchase swept up all the outstanding deferral stock. A corporation with deferral stock outstanding that buys back any of its shares during a year must report the total dollar amount purchased on its own return.
The value is fixed at vesting, and that is the risk the election creates. Section 83(i)(6) requires the corporation to certify that the stock is qualified stock and to notify the employee that the election is available, and it specifies what the notice must say. Among the required warnings: that the amount of income recognized at the end of the deferral period will be based on the value of the stock at the time the employee's rights first became transferable or ceased to be subject to a substantial risk of forfeiture, "notwithstanding whether the value of the stock has declined during the deferral period," and that the income will be subject to withholding at the rate determined under section 3402(t). The deferral is of the timing, not of the measurement. An employee who elects and then watches the company's valuation fall will be taxed on a number the shares no longer support, on shares that may still be unsellable.
Two narrower points. Stock is not qualified stock if the employee may sell it back to the corporation, or otherwise take cash instead of stock from the corporation, at the time their rights first become transferable or cease to be subject to a substantial risk of forfeiture, since in that case the liquidity problem the provision addresses does not exist. And all members of a controlled group under section 414(b) are treated as one corporation for the whole subsection, so the 80-percent plan test and the excluded-employee test cannot be managed by splitting a business into entities.
