I should probably ask these on the retirement plan forum but here goes:
(1) Can a traditional 401(k) still with an ex-employer be rolled over into an existing Solo 401(k) (assuming the latter plan permits rollovers)?
(2) What about an IRA, all of whose funds had one time originated in a former employer's 401(k)? Can it roll into the solo 401(k)?
(3) Can a solo 401(k) be restated as a 401(a) qualified plan? Are there implications to this other than paperwork and future contribution levels/formulas? (One I can think of is you could then have employees.)
Thanks,
Steve
