This question could go in either Entreprenurship or Investor Alley.
Those of us who do freelance work or have small businesses can shield our income from taxes, either now or in the future, by shoving it into 401(k) plans. Unfortunately, this can get complicated.
Solo 401(k)s can be had for minimal fees, but cause difficulties if you add an employee. They also don't have fully creditor protection and produce moderately heavy paperwork/compliance requirements.
Small business 401(k)s can be had for moderate prices, are designed to let you add an employee, and have full creditor protection. Unfortunately, they produce heavy paperwork/compliance requirements.
Enter multi-employer 401(k)s. They are run for groups of companies. They can be cheap due to economies of scale, it is easy to add an employee, they have full creditor protection, and the operator of the MEP does all of the paperwork.
The trick is finding one with an organization that you can join easily. Does anyone know of any decent MEPs with broad bases of membership?
