Get your taxes done using TurboTax

@wistful  If you buy one share of stock for a dollar and then it splits the basis is $0.50.  

 

If you sell one share and use one dollar for the basis on that sale then the basis on the remaining share is zero.  

 

So you are going to multiply the basis by the percentage of shares that you sold in this transaction.  If it doubled you should make sure that the percentage of shares that you have keeps that in mind.
