[URSpider94]

You’re still taxed on all of the gain. The initial taxation upon vesting would reset the basis. Any additional gains would be taxed when you sell the underlying shares. It would have done two things: a. Pull in revenue to an earlier date (a key factor in this tax plan, since all of the gain/loss calculations are on a 10-year timeline) and b. Lock in gains, even if the shares are later worthless. Yes, you can theoretically write off the losses, but only a few thousand dollars at a time if you don’t have offsetting gains.
