Here's what you need to know if you sell a house that a parent gave you while he or she was still living. By Kimberly Lankford, Contributing Editor November 28, 2011 Our mother, who is still alive, transferred the deed of her house to her children in 2006. We are now selling the home. Will we be taxed on the proceeds?Because your mom gave you and your siblings the house during her lifetime, you will have to use her basis -- what she paid for the house plus any improvements she made -- to calculate the gain. So if she bought the house in 1970 for $50,000 and made $25,000 in improvements, and you net $600,000 on the sale, then the $525,000 difference could be taxable. Had she left you the house in her will, the tax implications would be quite different. The cost basis of an inherited property is based on the fair-market value of the home at the time of death -- which would probably be much higher, resulting in a smaller taxable gain.
