The tax effect to Steven from the payment of the cash distribution on December 31 by Wildhorse Inc. is Dividend Income.
The cash distribution of $6,900 by Wildhorse Inc. above its current year's earnings of $3,900 does not reduce Steven's basis of stock and does not create a short-term capital gain.
Steven's ownership of Wildhorse Inc. = 100%
The purchase price of the stock on March 31 = $2,800
Cash distributed by Wildhorse Inc. on December 31 = $6,900
Earnings and profits for the year = $3,900
Thus, the tax effect shows that the cash distribution will be treated as dividend income to Steven.
