Found it? Your options
| Leave it | Often allowed if your balance is over $7,000. You keep the plan's investments and fees. |
| Move it to your new job's plan | If the new plan accepts roll-ins. Ask the new plan's recordkeeper. |
| Roll it into an IRA | More investment choices, and you control it. A direct rollover avoids withholding and penalties. |
| Cash out | Usually taxed, plus a 10% penalty if you are under 59½. |
