You can transfer old traditional IRAs, and any old 401(k) money (traditional OR Roth). You cannot transfer Roth IRAs into a solo 401(k). Contributions must come from self-employment income in the business the plan was opened for.
How do I initiate a transfer or Rollover to fund my Solo 401(k)?
You will email our support team to get a transfer process started. Login to your dashboard to find our support email. You can include an attached statement of the account you wish to roll over, whether that is a Traditional IRA, or an old traditional or Roth 401(k).
Remember that you cannot transfer in a ROTH IRA
What about if I have an old Solo 401(k) I want to roll into Rocket Dollar?
Please inform support right after purchasing a solo 401(k) into Rocket Dollar. You can see your support options in your client dashboard after purchasing. There are some additional steps to take over a Solo 401(k) that is already operational.
