ABC Corporation has always been a calendar C Corp until 1/1/08, when it made the election to switch to S Corp. It wants to engage in tax loss selling at the end of 2008, realizing $50,000 in capital losses. The same stocks had an unrealized loss of $20,000 on 1/1/08. There are no stocks with capital gains. No other assets were sold during the year. Will the capital loss realized now be C Corp loss eligible for capital loss carryback, or a K-1 capital loss pass-through, or both? Thank You.
