A Roth solo 401k plan
is excellent for self-employed individuals and is an excellent way to build towards retirement whilst minimizing taxes. With this plan, you can make your investments tax-free, and at the age of 59 and a half, you can start living off your investments. Those investments could include precious metals, real estate, private business investments, options, and currencies. You either declare your investments as "after-tax" or convert the funds that are already in your traditional plan to a Roth plan.
