My wife sold shares that were provided to her from 2016 through 2019 as part of an annual employee performance incentive program. The shares were valued at various processes and awarded over 5 years. They were sole in 2021 so they would be long-term gain. My question relates to the cost basis for calculating the gain. She paid $0 but at the time she was awarded the stock its cost basis was 42.58 in one instance (other prices in other instances). Should the stock cost basis be $0 or the cost basis of $42.58?
Thanks David
