I have a similar question. I don't know for sure what the cost basis is. My W2 has the amount of the RSU sale lumped into the total amount for gross pay. I can look at my paycheck when the RSU sale happened but I don't know if that is the cost basis or adjusted cost basis. I received a value of $10,000 but $2,800 were taken out and reported for taxes on the 1099-B in 1d. The net I received was $7,200. What is the cost basis I should report?
