A 401(k) rollover is the process of moving your retirement savings from a previous employer's plan into an IRA or your new employer's plan. This is typically done when you change jobs or retire. Rolling over can give you more investment options, consolidate your accounts, and provide more flexibility in managing distributions. However, rollover decisions involve tax, fee, and investment considerations that vary based on your individual situation. It is important to evaluate whether a rollover is in your best interest before making a decision. A direct rollover — where funds move directly between accounts — avoids mandatory withholding and potential tax consequences.
