Over the past few years, more and more workers have become gig workers. In reality, they are just sole proprietors, that make a living, project to project.
Their retirement savings usually revolve around SEPs, SIMPLE-IRAs, and Solo 401(k)s. I once worked on a multiple-employer plan, made up of this gig, freelance workers. The only problem is way too expensive and not very good. I think if you have the distribution channel, a solo 401(k) PEP can be successful. It has the opportunity to offer assistance to gig workers when those other small plans give absolutely no investment help when they open an account at one of the brokerage firms.
