Q&A: Here’s why two 401(k) accounts aren’t better than one

Dear Liz: I changed jobs more than three years ago and did not roll over my 401(k) when I started a 401(k) account with my new employer. I’m perfectly happy having separate accounts. However, I’ve read some IRS rules that I cannot understand about being penalized for not contributing to a 401(k) for five years. So my question: After turning 59½, will I face any sort of penalty or loss when I begin withdrawing funds from a 401(k) account that has been sitting idle?

Answer: There’s no penalty for not contributing to an old 401(k). In fact, you cannot contribute to an old 401(k). Once you leave the employer that sponsored the plan, you generally can’t put any more money into it.

What you may have stumbled upon are IRS rules that apply to employers who sponsor 401(k) plans that have a profit-sharing component.

Employers aren’t required to make contributions to these plans every year — there may be years when there’s no profit to share — but their contributions have to be “recurring and substantial.” If the employer hasn’t made contributions in three of the past five consecutive years, the plan could be terminated, said Mark Luscombe, principal analyst for Wolters Kluwer Tax & Accounting.

That obviously doesn’t apply to your situation, and if you want to continue managing two 401(k) accounts, you’re welcome to do so. But consider rolling the money into your new employer’s plan, if it’s a good one and accepts such transfers. That would mean one fewer account you need to track and also could give you access to more money if you wanted to take out a loan.
