He will have to wait till April 15, 2015, to open his Solo 401k account.

  • In the case of C-Corporation, the deadline is April 15 which is extendable to October 15.
  • If the entity is an LLC taxed as a Sole Proprietorship, the final date is the same as in case of C-Corporation.
  • If the entity is an S-Corporation, the deadline is the same as in case of the entity type of LLC taxed as a partnership.
  • If the entity type is a Sole Proprietorship, the deadline is also April 15 and extendable to October 15 if you file a tax return.
  • In case of an LLC taxed as an S-Corporation, the deadline is also March 15 which is extendable to September 15.
