Should You Leave Your 401(k) With Your Former Employer or Roll It Over?

After leaving a job, you may have several options for your 401(k), including leaving it in the former employer’s plan, rolling it into an eligible retirement account, or considering another permitted option. The available choices and tradeoffs depend on the plan, fees, investment options, tax rules, and your circumstances.

So, you left your job.

Now you have an old 401(k).

The question is: Do you leave it there, or roll it over?

There isn't one answer that applies to everyone. The decision is about understanding your options and how each one fits into your retirement plan.

What are your options?

Depending on your plan and circumstances, you may be able to:

Leave the money in your former employer’s plan.

Roll eligible assets into an IRA.

Roll eligible assets into a new employer’s retirement plan, if the plan accepts rollovers.

Take a distribution, understanding that taxes and possible penalties may apply.

Not every option is available in every situation. Your plan’s rules and the type of account or assets involved matter.

What should you compare before deciding?

Start with the former plan's investment options and fees.

Then compare those with the available options in a potential destination account or plan.

Look beyond the investment menu. Consider account services, withdrawal rules, creditor protections, loan provisions, and other features that may apply. These can differ between employer plans and IRAs.

A rollover can change more than where the account is held.

How can fees and investment options affect the decision?

Different plans and accounts may have different administrative fees, investment expenses, and available investments.

But comparing fees alone may not tell the whole story. You also need to understand the services and features associated with those costs.

Likewise, a larger investment menu does not automatically mean a better outcome. What matters is whether the available choices fit your needs and how you plan to manage the account.

What tax issues should you understand?

A properly completed direct rollover of eligible assets to an eligible retirement account generally can avoid current taxation.

But the details matter.

An indirect rollover, a distribution paid to you, a rollover involving Roth and pre-tax assets, or a transaction involving employer stock may have different tax consequences or requirements.

Before moving money, confirm the account types, eligible assets, receiving account, and applicable rollover rules. A mistake can create an unexpected tax bill or other consequences.

Could leaving the money in the plan have advantages?

It may.

Some employer plans offer features that are not identical to those available in an IRA. Depending on the plan and your circumstances, those features may include particular investment options, withdrawal provisions, or creditor protections.

On the other hand, keeping an old account may mean managing another account with its own rules and fees.

The details of the specific plan matter.

How does the account fit into your retirement plan?

Here's the thing.

An old 401(k) is one part of your overall financial picture.

You may have other retirement accounts, taxable investments, cash, or income sources. How the 401(k) fits with those resources can affect how you think about account structure, withdrawals, and investment management.

The question isn't simply, “Should I always roll over an old 401(k)?”

A more useful question is:

“What are the available options, and what are the tradeoffs for my situation?”

That’s where the decision starts.
