Don’t forget profit sharing as well. As a small business owner I researched the difference between a defined benefits plan verses a 401k and profit sharing. You actually can do better with a defined benefits program but there are some potential risks due to the obligatory contributions. Anyways at least for my a 401k plus a profit sharing plan worked out best. I spoke with Rob Butterfield (part of the braintrust from Ray Lucia’s show)about it, he was quite helpful.
