I believe you can set up an installment plan for the Sale of a closely held S-corp.   Client sold their S-corp via installment sale, the note was transferred to each shareholder individually.     The K-1 arrived with  the entire gain from the sale in box 8 of the K-1.  Client is receiving proceeds over the next 5 years.  I was hoping to fill out the form 6252 for this gain.   Does anyone know how to create an installment sale on the individual return using the K-1 information.   Do I need to contact the accountant that did the K-1 for additional information?
