When you leave an employer, an old 401(k) can usually stay where it is, move to a new employer plan, roll into an IRA, or be handled another way depending on the situation. The best choice depends on costs, investment options, tax treatment, creditor protections, and how much guidance you need.
Start with fees and investment choices. Some employer plans are cost-effective and simple. Others are limited or hard to manage alongside the rest of your financial life. Also review whether the plan offers features that matter to you, such as loan access, stable value options, or institutional share classes.
Tax details matter. Traditional, Roth, and after-tax balances should be reviewed carefully before anything moves. If you feel rushed, pause and ask for a second opinion before signing transfer paperwork.
