I inherited stock from my dad, who passed away on a Saturday in 2010. I sold the shares in 2014, and I am trying to figure out the cost basis for my taxes. When stepping up the cost basis, do I use the price from the Friday before he died or the Monday afterward?
Ordinarily, you take the average of the highest and lowest quoted selling prices on the date the original owner died to come up with the cost basis for inherited stock. But if the owner died on a weekend, you do that calculation for Friday and Monday and average those two numbers, says Jerry Love, a certified public accountant in Abilene, Texas.
To track down the high and low figure for an old date, Love uses BigCharts.com. Click on “historical quotes” and enter the stock symbol and date to get the high, low and closing price and a chart of the stock’s performance on that date.
