Sheila had been an audit manager at a large CPA firm. She accepted a job at one of her clients, a start-up company, and began work on February 15, 2021. On the day she started, as part of her compensation package, she received 500 shares of start-up company stock. The stock is restricted stock in that it is subject to a 5-year cliff vesting period, i.e. the stock will not legally be Sheilas unless she is still employed by the Company on February 14, 2026. The stock, on February 15, 2021, was valued at $1.00 per share. Assume that the stock will be worth $51.00 per share on February 14, 2026. Assuming Sheila does nothing with respect to the stock grant, must she recognize any income? If so, when and how much? Are there any options available to Sheila as to how much income must be recognized and when? Assuming there are options—which option might Sheila choose and why?
