First notice from TD Ameritrade said we owed $44k. My CPA said that was an accounting mistake and we should not owe anything. I called TDA's tax department and said we weren't paying this and not to file the 990-T until they figured out what PWC, Foresight's accounting firm, did wrong. They sent it back to be reviewed. Just got a corrected 990-T saying we now owe $8k. Still not paying. Will have to go back to CPA and call TDA again. What a hassle...
