Deferred Compensation Stock Sale Basis
While working, I received stock over multiple years as part of a deferred compensation plan. Now retired, I sold some of the stock. On the 1099-B it is listed as "Non-Covered". What do I report as the tax basis? a) the stock value when it was awarded? b) the stock value when I retired? c) $0 because I actually paid nothing out of pocket for the stock?
