Solo 401k and the Self-Directed IRA are the well-known types of self-directed retirement accounts. Pre-tax and Roth after-tax contributions can be made to these accounts.

Differences between Self-Directed IRA and Solo 401k

On the other hand, transfers or rollovers to self-directed IRAs are reported annually on Form 5498 by the receiving self-directed custodian by May of the year following the rollover. Rollovers from IRA to a Solo 401k or self-directed IRA are reported on lines 15a and 15b of Form 1040.

  12. At termination, Solo 401k file Final Form 5500-EZ and 1099-R, self-directed IRA only files Form 1099-R.
