Imagine that you are a sole proprietor with a high income, and you’re looking for a way to maximize your retirement savings while reducing your taxable income. You’ve heard about SIMPLE IRAs and SEP IRAs, and you used to contribute to a 401(k) when you had a corporate job. Did you know that it is simple to set up your own 401(k) and you can contribute up to $61,000 a year to it ($67,500 if over age 50)? Introducing the Individual 401(k)! Individual 401(k)s are also known as Solo 401(k)s, Solo-ks, Single-ks, Self-Employed 401(k)s, Uni-ks and One-participant ks. This type of plan is like a traditional 401(k) covering business owners with no other employees. The plan can also cover the business owner’s spouse. It is also possible for the business to have employees, but they cannot be full time, as defined by the plan document.
