I recently left my employer to RE at age of 49. My original plan was to keep all my money in my 401(k) (managed by Vanguard), instead of rolling it over into an IRA for the following reasons:
The problem is now that I was engaging in a megabackdoor-Roth and I still have about 12500 USD in after-tax contributions in my account. Before I left my company I called the 401(k) provider, and asked about partial transfers after end of service, in particular, if I still could transfer the after-tax money out after end-of-service. While they told me "no" about partial transfers in general, they told me "yes" about the transfer of after-tax money. Now that I've left, they tell me that no partial transfer is possible and that there was a "misunderstanding" in that phone call.
So I am wondering, if there is any alternative to rolling the entire account over to an IRA.
One alternative I looked at is to open a Solo 401(k). I won't have any self-employment income (for the foreseeable time), so I can't make any contributions, but that apparently doesn't prohibit me from opening one and rolling my 401(k) in. However this unfortunately only solves problem 1 (backdoor IRA). It doesn't solve the asset protection problem, since Solo 401(k)s are apparently not subject to ERISA either and have the same (in my case weak) assets protections as IRAs.
Does anyone know any other options?
