Dear Tax Talk,
I need to find the cost basis for an inherited family house that I sold. It was jointly inherited by my brother and me in 2001. I inherited his half when he died in 2011. Is there a formula for calculating the cost basis of an inherited home to report capital gains?

Dear Jean,
To calculate your basis in the family home you are selling, you will need to know the value of the home when you inherited it with your brother in 2001 and also the value of the home when your brother died in 2011.

When real estate is inherited, it receives a step up in basis to the date-of-death value. Your situation is especially complicated by the fact that you inherited 50 percent of the property in 2001 and then the other 50 percent in 2011. So let’s say in 2001, the family house had a fair market value of \$200,000 when you and your brother inherited it. Your 50 percent share at that time had a basis of \$100,000. Now let’s say that when your brother died in 2011, the fair market value of the house was \$300,000. You then inherited his 50 percent share and your basis for this portion of the property was \$150,000.

You now own 100 percent of the property and your basis is \$250,000 (\$100,000 from 2001 and \$150,000 from 2011). When you sell the property, you will take the gross amount realized from the sale less the selling costs and your “basis” to arrive at your gain or loss that will be reported on your tax return.

Thanks for the great question and all the best to you.
