can i open a solo 401(k) if i am an independent contractor but also work part-time as an employee?
user
if you have self-employment income you can open a solo 401k.  your question is unclear as to what your employment status is.  if you are self-employed as an independent contractor, you can open a solo 401k.  you can still do this even if you also earn non-self-employment income (i.e., you are an employee and receive a w-2).  however, the limits for contributions to a solo 401k are based on your self-mployment income, not your total income, so if you have only a small amount of self-employment income, you won't be able to contribute much to the solo 401k.  you may be able to reduce your taxes somewhat, but it's not like you can earn $1000 of self-employment income, open a solo 401k, and dump $5000 into it; the limits don't work that way.
