An employer has no obligation to pay employment taxes or to withhold federal income taxes upon the grant of NQSOs, unless the plan fails to place itself in the desired exception to Section 409A. In that case, Section 409A taxation, reporting, and withholding would be required. Under Section 83 (assuming exception from Section 409A coverage), on exercise, the employer must treat the excess of the market value of shares received over the grant price as wages subject to FICA, FUTA, and federal income tax withholding in the pay period in which the income arises. The employer has no obligation to withhold or pay federal income or employment taxes on the sale of shares purchased by option.
Employers are to use code “V” in Box 12 on Form W-2 to identify the amount of compensation to be included in an employee’s wages in connection with the exercise of an employer-provided NQSO. Completion of code V is addressed in the instructions for Forms W-2 and W-3. Employers must report the excess of the fair market value of the stock received on exercise of the option over the amount paid for that stock on Form W-2 in boxes 1, 3 (up to the Social Security wage base), 5, and 12 (using code V) when an employee (or former employee) exercises his or her options.
1 If an employer were to fail to claim the exception to 409A and violate Section 409A, it would follow reporting and withholding required for Section 409A plans ( Q
3541).
