Dear Liz: I have just retired. I have a 401(k) from work. Do I keep it as is or do I roll it over into an IRA?

Answer: Investment companies and their representatives like to push the idea of rollovers as the best option, but that may profit them more than it does you.

Leaving your money in your employer’s 401(k) has several potential advantages. Many 401(k)s offer access to institutional funds, which can be much cheaper than the retail funds available to IRA investors. Workplace retirement plans also offer unlimited protection from creditors if you’re sued or forced to file bankruptcy. An IRA’s bankruptcy exemption is limited to $1,283,025, and protection from creditors’ claims varies by state. (In California, for example, only amounts “necessary for support” are out of reach of creditors.)

If you retired early, you can access your 401(k) without penalty at age 55. The typical age to avoid penalties from IRA withdrawals is 59½.

You may opt for a rollover if your 401(k) offers only expensive or poorly performing options. Even if you decide to roll over the rest of your 401(k), though, get a tax pro’s advice before you roll over any company stock. You may be better off transferring the stock to a taxable account now so you can let future appreciation qualify for capital gains rates. Ask your tax pro how best to take advantage of this “net unrealized appreciation.”
