this is from reg 1-83-2(a)
In computing the gain or loss from the subsequent sale or exchange of such property, its basis shall be the amount paid for the property increased by the amount included in gross income under section 83(b). If property for which a section 83(b) election is in effect is forfeited while substantially nonvested, such forfeiture shall be treated as a sale or exchange upon which there is realized a loss equal to the excess (if any) of—
(1) The amount paid (if any) for such property, over,
(2) The amount realized (if any) upon such forfeiture.
If such property is a capital asset in the hands of the taxpayer, such loss shall be a capital loss. A sale or other disposition of the property that is in substance a forfeiture, or is made in contemplation of a forfeiture, shall be treated as a forfeiture under the two immediately preceding sentences.
thus if not substantially vested, you cannot take a loss deduction for the amount of income included in your w-2.
