What contributions can be made to a 401(k)/Profit Sharing Plan?
First realize that a 401(k) plan is really a profit sharing plan that may or may not utilize a profit sharing component in addition to the 401(k) salary deferrals. You might think of the plan as a double-decker bus in that you can use either tier (profit sharing or 401(k) feature), or both tiers (profit sharing and 401(k) features).
