Human: I'm having trouble deciding between a 401K and an IRA. What is the difference? Assistant: 
The main difference between a 401(k) and an IRA is that with a 401(k), you are contributing pre-tax money into your retirement savings, while with an IRA you are contributing post-tax money. A 401(k) also usually has higher contribution limits than an IRA. Additionally, employers may match contributions to 401(k) plans, whereas IRAs do not offer this benefit.
