What Should You Do With an Old 401(k)? Understanding Your Options

Changing jobs or retiring often means making a decision about your old retirement plan. Whether you have a 401(k), 403(b), or 457 plan, the money doesn't automatically follow you when you leave your employer.

For many people, an old workplace retirement account is one of their largest financial assets. Deciding what to do with it isn't simply administrative—it can affect your taxes, investment options, retirement income strategy, and even creditor protection.

Fortunately, you generally have several options. The right choice depends on your financial situation, your new employer's retirement plan, and your long-term goals.

Option 1: Leave the Money in Your Former Employer's Plan

If your former employer's retirement plan allows it, you may be able to leave your account where it is after you leave the company. While you generally won't be able to make additional contributions, keeping your savings in the existing plan may be worth considering depending on your circumstances.

PROS:

If you leave your job during or after the year you turn age 55, you may be able to take penalty-free withdrawals under the IRS age-55 rule, though ordinary income taxes may still apply.
If your account includes employer stock, you may qualify for favorable tax treatment under the Net Unrealized Appreciation (NUA) rules.
Employer-sponsored retirement plans generally provide federal creditor protections, and some plans may offer additional features that aren't available in other retirement accounts.

CONS:

Managing retirement savings across multiple employer plans can make it harder to keep track of your investments.
Your ability to leave your retirement savings in your former employer's plan depends on the plan's rules. Under federal law, plans may require accounts with vested balances of $7,000 or less to be moved out of the plan.
Your former employer may change investment options or other plan features over time.
Withdrawal options may be more limited than those available through other retirement accounts.
Your investment choices are limited to the options offered by the plan.
The plan's fees, investment options, or distribution features may no longer align with your retirement goals.

How to Execute: Contact your former employer's plan administrator to confirm that you're eligible to keep your account in the plan. Ask whether there are any balance requirements, fees, or restrictions that apply to former employees.

Before Making Your Decision: Leaving your retirement savings with a former employer can be a practical choice in some situations. Before deciding, compare this option with the alternatives by considering factors such as investment choices, fees, withdrawal flexibility, creditor protections, and how the account fits into your overall retirement strategy.

Option 2: Roll It Into Your New Employer's Plan

If you've started a new job, your new employer may allow you to transfer your old retirement plan into its workplace retirement plan. Not every employer accepts rollovers, so you'll need to check whether this option is available.

PROS:

Consolidating retirement savings into one workplace plan can make your accounts easier to manage.
A direct rollover generally isn't a taxable event when completed correctly.
You'll continue to benefit from the features, creditor protections, and investment options offered by your new employer's retirement plan.

CONS:

Your new employer may not accept rollovers from a previous employer's plan.
Your investment choices will be limited to those offered by the new plan.
You may need to wait until you're eligible to participate before completing the rollover.
The fees, investment options, or plan features may be different from those in your previous plan.

How to Execute: Contact the HR department at your new employer and ask them to put you in touch with the plan administrator. If the transfer is possible, they may give you instructions on how to complete the move.

Before Making Your Decision: To decide if this is the right option for you, you'll need to evaluate factors like fees, investment availability, enrollment periods, and your personal goals.

Option 3: Cash Out Your Account

You generally have the option to withdraw the money from your old employer retirement plan instead of leaving it in a retirement account. While this provides immediate access to your savings, it can also trigger taxes, penalties, and reduce the money available for your future retirement.

PROS:

You'll receive immediate access to your retirement savings.
This option may help if you have an immediate financial need and no better alternatives.

CONS:

The distribution is generally subject to ordinary income taxes.
If the payment is made directly to you and is eligible for rollover, the plan is generally required to withhold 20% for federal income taxes.
If you're under age 59½ and don't qualify for an exception, you may also owe a 10% additional tax on early withdrawals.
Cashing out reduces the amount of retirement savings that can continue growing on a tax-advantaged basis.
Once the money is spent, it may be difficult to replace those retirement savings.

How to Execute: Contact your former employer's plan administrator and request a distribution. Before moving forward, make sure you understand the potential tax consequences and any withholding requirements that may apply.

Before Making Your Decision: Cashing out your retirement savings may be appropriate in limited circumstances, but it's often the option with the greatest long-term cost. Before taking a distribution, consider whether another option could help preserve the tax advantages of your retirement savings while still meeting your financial needs.

Option 4: Complete an Indirect IRA Rollover

With an indirect rollover, your former employer's retirement plan sends the distribution to you instead of directly to your new IRA. To avoid taxes and potential penalties, you generally must deposit the full amount into an eligible retirement account within 60 days. Because there are several IRS rules and deadlines to follow, this option requires careful attention to timing and paperwork.

PROS:

If completed correctly, you'll receive the same potential long-term benefits as moving your retirement savings into an IRA through a direct rollover.
An IRA may provide access to a broader range of investment options than many employer-sponsored retirement plans.
Depending on the IRA you choose, you may have additional flexibility when developing your retirement income strategy.

CONS:

You must deposit the full distribution into an eligible retirement account within 60 days or the taxable portion may become subject to income taxes and possible penalties.
If you're under age 59½ and the rollover isn't completed correctly, you may also owe a 10% additional tax unless an exception applies.
Eligible rollover distributions paid directly to you generally require 20% federal income tax withholding, so you'll need to replace the withheld amount from other funds to complete a full rollover.
Certain withdrawal rules differ between employer-sponsored plans and IRAs, including some early withdrawal exceptions.
Depending on the IRA you choose, fees, investment options, services, and creditor protections may differ from those offered by your employer's plan.

How to Execute: Request a distribution from your former employer's retirement plan. Once you receive the funds, deposit the full amount into an eligible IRA or other qualified retirement plan within 60 days. If taxes were withheld from the distribution, you'll generally need to replace that amount from other funds to complete a full rollover.

Before Making Your Decision: An indirect rollover can accomplish the same goal as a direct rollover, but it involves additional paperwork, strict deadlines, and mandatory withholding rules. Before choosing this option, consider whether a direct rollover could provide a simpler way to move your retirement savings while avoiding unnecessary complications.

Option 5: Roll Your Savings Directly Into an IRA

A direct rollover moves your retirement savings directly from your former employer's retirement plan to an IRA without the money passing through your hands. Because the transfer is completed between financial institutions, it generally avoids the mandatory withholding requirements and strict deadlines associated with indirect rollovers.

PROS:

A properly completed direct rollover generally isn't a taxable event.
Mandatory 20% federal withholding generally doesn't apply because the distribution isn't paid directly to you.
An IRA may provide access to a broader range of investment choices than many employer-sponsored retirement plans.
An IRA can offer additional flexibility as you build your retirement income strategy.
This option reduces the risk of missing the 60-day deadline that applies to indirect rollovers.

CONS:

You'll need to complete paperwork with your former employer's plan administrator and your new IRA provider.
IRA fees and available services vary by financial institution.
Certain withdrawal rules differ between employer-sponsored plans and IRAs, including some early withdrawal exceptions.
Employer-sponsored retirement plans may provide different creditor protections than IRAs; IRA protections are generally governed by state law and vary by state.

How to Execute: Contact your former employer's retirement plan administrator and request a direct rollover to an IRA. They'll provide instructions for transferring the funds directly to your new IRA custodian.

Before Making Your Decision: A direct rollover can simplify the process of moving retirement savings, but it's also a good opportunity to think about how your retirement accounts fit into your long-term plan. For example, moving money to a traditional IRA may change how Required Minimum Distribution (RMD) rules apply in retirement, while Roth IRAs and Roth employer plans now have different RMD rules than they did in the past. If you're unsure how these rules affect your situation, a financial professional can help you compare your options before making a move.
