This is a little complicated.
Forty years ago I purchased AT&T stock under the employees stock purchase plan. The stock was put in my name and joint with my daughter. I have all records of dividend reinvestments, etc, so I have a good handle on the total price paid per share. It is considerably less than the current price per share.
My question is on transferring the stock to the revocable declaration of trust of my daughter and her husband. Who has to pay the capital gains on the current price of the stock vs what is the cost basis. Does my daughter have to declare half of the capital gains and I report the other half of the capital gains? Or, could either one of us declare the total capital gains?
