This survey was actually specific to plans accessed through an employer. But what do you do if you are or you are self-employed? If you own a business with just yourself (or you and a spouse), a Solo 401k plan may be an even better solution for you!
401Ks are similar to IRA plans. However, IRA plans are set up on an individual basis and not set-up by an employer. A 401K is set up by an employer.
