Answer:
$500 short-term capital gain
Step-by-step explanation:
Henrietta's gain = selling price - stock's basis = $13,500 - $13,000 = $500
Since Henrietta received the stocks on June 1, 2015, and sold them on January 1, 2016, only 7 months had passed, therefore, this transaction would be considered a short term capital gain.
When a gift is sold (in this case the stocks), a taxpayer can use the basis for computing gains. If the stocks were sold at a loss, Henrietta should use the lower value (at the moment of the gift) to determine her loss.
