Solo 401k Age Limitations

[Todd Goedeke]

When contributing to a Solo 401k it is mandatory that all employee contributions cease before age 70 1/2, employer contributions may continue as long as self employment earnings continue.Comments please?

The employer contribution can continue to be maximized up to Solo401k limits?

When taking the RMD from a Solo401k , a mandatory 20% is required to be withheld and sent in by the 15th of the month following in which the RMD took place. If a person makes quarterly estimated tax deposits, can the 20% withheld from the RMD be considered as part of one's quarterly deposit?

If a Solo401k owner wants to continue receiving the benefits of leverage with real estate after age 70 1/2 , no UFI, and yet avoid 20% withholding on the RMD, does it make sense to transfer to an IRA those assets not invested in leveraged real estate?

Can you transfer assets from a 401k to a Solo401k after age 70 1/2 for the purpose of avoiding limitations of an IRA?
