The company offers 401(k) but doesn't match your contribution at all. In this case, it worth investing in 401(k)? For what reasons might a 401(k) be preferred over an IRA if there is no match?

However, 401(k) plans also have downsides. Inside a 401(k), you are generally limited to a handful of investment fund options selected by your employer. With some plans, you might find that your only investment options come with high expenses. With an IRA, you can invest in almost anything you want.
