There are approximately 15 million accounts like this, which have been left behind by ex-employees. This is primarily due to confusion or inertia over strict rules for moving money. You don’t have 60 days to make a decision. The IRS won’t allow you to procrastinate on a crucial decision.

* Option No. 1: Cash Out

This is not a good idea unless you are in serious financial trouble and absolutely need the money to live on.

“Cashing out comes with an immediate price, both in terms of giving up potential future gains in your portfolio and in the IRS taxes the company handling your 401(k) for your former employer is legally obliged to withhold,”Nupur Bahal (Vice President for Retirement at Fidelity Investments), explains. “That’s money you won’t have for retirement.”

IRAs not only offer more investment options than the traditional 401(k), but also allow you to withdraw penalty-free for qualified education expenses and up to $10,000 for a home purchase.

“Especially if you already have other, non-401(k) accounts elsewhere, it may be simpler and more effective to consolidate everything under one roof,”Bahal.

* Option No. 4: Leave It With Your Ex-Employer

People who are 55 or older can withdraw their funds without penalty. IRAs — or unique investment options might just be worth letting things roll. Some people forget that the account is still there after the passing of time. Further contributions are not allowed.

No matter what you do, the clock is ticking to remind you to call your old 401k administrator if you want to withdraw even a dime.
