S Corp converted to SMLLC - 401K Plan

[David]

Single shareholder S Corp is considering changing to a SMLLC. I know the S Corp will have to be dissolved and there could be a taxable event for fixed assets transferred to the SMLLC.

 

Since payroll will not be processed how is the full 401K contributions/deferred salary issue handled on Sch C and the 1040 for the SMLLC? The TP also gets the catch up contributions. She has maxed the 401K benefits in past years.

 

Since the TP is now a SMLLC is the only option available a SEP, SIMPLE or other retirement plan except a 401K?

 

Thanks.
