Look, you are very confused and you need to consult with a tax professional.
They know about it. Why do you think that they are asking for the tax? What they don't know about is the cost basis because you did not file a return. Therefore, they assume that the whole enchilada is taxable income.Not exactly, the are asking me to pay $2700 based solely on the $45K that was reported as income rec'd in 2003. They do not know anything about the sale of the house yet.
