<human>: What is the difference between a 401k and a 401a?
<bot>: The main difference between a 401(k) and a 401a plan is that a 401(k) plan allows employees to save for retirement through an employer-sponsored plan, while a 401a plan does not. A 401a plan may be more beneficial than a 401(k) plan if it offers higher contributions, lower fees, or other benefits.
