I am currently the sole proprietor of a very small business (it's just me, and I won't ever have employees), but my CPA has advised me to transition to an S Corp. I will be consulting an attorney to do this shortly. But I'm looking to know more about my options for opening a Solo 401k. I would like something simple, with electronic deposits, and ideally low fees. Fidelity looks like one good option, and possibly Vanguard. Can anyone give some advice? Previously, I have been putting money into a SEP IRA through Betterment which has been easy and convenient but the fees aren't great.
Thanks in advance for any assistance.
