Starting a new job? Don't forget your 401(k) at your old one

  • When changing jobs, don't forget about the money you've stashed in your former employer's 401(k) plan.
  • Savers can keep their old 401(k) account, roll funds into a new 401(k) or an IRA, or cash out.
  • Cashing out is rarely a good idea, as savers under age 59½ pay a 10 percent penalty on top of any taxes owed.

In the middle of all the excitement that comes with landing that new job, make sure you don't forget about the retirement money you already socked away in your former employer's 401(k) plan.

That's the advice offered by Rianka Dorsainvil, a millennial certified financial planner and owner of Your Greatest Contribution.

Dorsainvil says it's important for everyone to understand all the options available to when it comes to 401(k) plans. There are four ways to go: Roll the money into a new employer's 401(k) plan, move it into an individual retirement account, keep it in your former employer's 401(k) plan, or cash out your old account.

Almost all 401(k) plans now accept rollovers from other retirement plans. And consolidating your retirement money does make it easier to manage, Dorsainvil admits.

When rolling the 401(k) money into an IRA, it's important to check all of the fees and expenses that may be associated with that move, she said. This choice does give you more control and flexibility.

Keeping your money in your former employer's plan is your legal right if you have at least $5,000 in your account. Dorsainvil suggests you ask how long you have to decide. In most cases, you get 30 to 90 days.

The last option is cashing out the 401(k) plan. "It's an option, but not the best option," she said. She urges anyone weighing this decision to think long and hard before doing this. It's almost never the best choice, she said.

Dorsainvil points out that, in addition to paying the federal and state income tax owed when anyone cashes out a 401(k), investors younger than 59½ have to pay an additional 10 percent early withdrawal penalty.

There are obviously many factors to consider when it comes to a 401(k) rollover, and they are based on personal circumstances. Dorsainvil urges that everyone do their homework and seek a financial expert to help them make a smart decision.
