Human: What are the benefits of a 401K retirement plan? Assistant: 
The primary benefit of a 401(k) retirement plan is that it allows you to save for retirement while deferring taxes. You can also make contributions pre-tax, meaning your savings are tax-deferred until you withdraw them in retirement. Additionally, employers may match some or all of your contributions, which can significantly increase your savings potential. Finally, 401(k) plans offer many investment options and professional advice, so they provide an opportunity to maximize returns on your retirement savings.
