• Keep your money in your former employer's plan
  • Roll the money over into a new 401(k) plan or IRA You do have the option of cashing out, but unless you are 59.5 you will have to pay the tax and the 10-percent penalty to the IRS.

    If you decide to roll it over into another 401(k) or IRA, MAKE SURE you don't let the check be written to you. The check has to be written to go directly into the new account. There is no grace period for putting the money into the new account. If it does come to you rather than the new account, you'll be charged the tax and the 10-percent fine.

    If you choose to keep your money in your former employer's plan, then there are also a couple of requirements. First, you have to have a fully vested total of at least $5,000 in your account, and second, you have to be under the plan's normal retirement age (usually 65).
