A shareholder of an S corp has a $100 basis and owns 50% of the S corp. The S corp has the following balances: AAA $34 AEP $100 OAA $100 prior to making a distribution. The S corp makes a $200 distribution. What is the shareholder's basis after the distribution. From what I gather distributions that come out of AAA will reduce basis but I m not sure if this is the case when there is a balance is AAA, AEP and OAA as well. Also I show an OAA balance of $34 after the distribution. Does this have any impact on basis? Please show calculations.
