Does Son Impact Eligibility QUESTION

I own a business and my son is a non-owner full time employee. Can I still open a solo 401k for both of us? Or just me?

Unless your son is under age 21you won’t be able to open a solo 401k plan because he is a full-time employee (i.e., he works over 1,000 or more hours per year) in your business. 
The solo 401k rules allow for the exclusion of W-2 employees under age 21 regardless if they work 1,000 or more hours per year in the business.
