The solo 401(k) plan – often termed the single 401(k), individual 401(k) plans, or solo(k) – is for business owners without full-time employees (with the exception of a business partner or spouse).

How Does a Single(k)® Plan Work?

One of Ubiquity’s solo 401(k) plan offerings, Single(k), offers a unique path for self-employed professionals to secure their future retirement.

The plan allows business owners to set aside more money for retirement compared to other individual retirement savings plan options, like a traditional or Roth IRA.

It combines the features of a group 401(k) and a profit-sharing plan, enabling business owners to act both as the employee and employer.

This plan is an exceptional alternative to other retirement-investing avenues for sole proprietors, consultants, freelancers, and any business owner operating without full-time staff.
