@Edward MccrackenLikely your only option is to contribute to your employer plan.A Solo 401k plan is designed for someone who is self employed, and any contributions to such a plan would have to come from your self-employment income - not from your W-2 income from your employer.If your intention is to leave that money in the plan and have it grow tax-deferred, then contributing and reducing your taxes makes sense.If you think there is a higher than 50% likelihood that you will borrow the funds back out of the plan, then you may as well just not contribute in the first place.
