I just sold some ESPP stock for the first time and I'm unsure about the cost basis calculation. The stock was not bought at a discounted price. However, the company did offer a 15 cent on the dollar match. I'm not sure if or how the company contribution affects the cost basis. I received a 1099-B however there is no cost basis on it.
There is a purchase information attachment that includes sale date, proceeds, a from and to date of when the shares were purchased and a purchase basis column.
I think that the purchase basis column would be my cost basis. However, in the turbo tax screen where the ESPP sale details are entered there is a box for "Adjusted cost basis" and another for "Amount of compensation income for the sale" and I am unsure as to whether those boxes woud apply to my situation.
