Can my mom sell her house, and transfer all the proceeds to me, $300k, (to build her a new house) without being taxed as a gift?

I am trying to avoid paying taxes on the transfer of funds, which would be wired to me at the closing of the sale.  I will be using the funds to build her a new home.

Your mom is not giving you the money. She is hiring you to build her a new house, is that correct?

The gift tax has high limits and your mom probably would not pay a gift tax, depending on prior gifts. The lifetime exclusion is over $11 million. If your mom has passed that mark and is giving you the money, then it would be taxable. See About Form 709, United States Gift (and Generation-Skipping Transfer) Tax Return.

IRS definition of a gift:

You make a gift if you give property (including money), or the use of or income from property, without expecting to receive something of at least equal value in return.
