The property's FMV is included in decedent's Estate to the extent of the percentage that the decedent contributed toward the purchase.
Since Fred contributed 20% of the land,
So 20% of its $300,000 = $60,000
(+) Ethel's basis of land = $80,000
Total = $140,000
The requirement is to determine Ethel’s basis for the property after the death of the joint tenant (Fred).
When property is held in joint tenancy by other than spouses, the property’s FMV is included in a decedent’s estate to the extent of the percentage that the decedent contributed toward the purchase.
Since Fred furnished 20% of the land’s purchase price, 20% of its $300,000 fair market value, or $60,000 is included in Ethel’s estate.
Thus, Ethel’s basis is $60,000 plus the $80,000 of purchase price that she furnished, a total of $140,000.
