What should I do with my 401(k) when I leave my job?
It is one of the most common questions people ask at a major career or life transition. And it’s an important one to get right. Whether you left for a new job, received an unexpected layoff notice, or are finally crossing the finish line into retirement, you need to answer the same question: what happens to the money you have been building in your 401(k)?
Your situation should shape what the right answer is. A 42-year-old who just landed a better opportunity at a new company has different options and priorities than a 58-year-old who was unexpectedly laid off, or a 64-year-old who just retired after 30 years with the same employer. All three face an important decision, however, the stakes, timeline, and path forward are different.
Here in Iowa and across the Midwest, this is one of the most important conversations we have with clients at RetireRight. Getting this decision right can protect your savings, reduce your taxes, and set your retirement income strategy up for success. Getting it wrong can trigger unnecessary taxes, penalties, and missed opportunities that are hard to recover from. Here is how to think about it.
Why This Decision Matters More Than Most People Realize
For most people, their 401(k) represents one of the two or three largest financial assets they own. It has been growing, compounding, and building over years or decades of contributions and employer matches. The decision about what to do with it at a job transition is not just an administrative task. It is a financial planning decision with long-term consequences.
The wrong move can trigger an avoidable tax bill. A cash-out of a 401(k) before age 59 and a half results in ordinary income taxes plus a 10% early withdrawal penalty. This means someone in a moderate tax bracket can lose 30% or more of the balance to taxes and penalties with a single decision. Even for those past 59 and a half, a lump-sum withdrawal can push you into a higher tax bracket and affect Medicare premiums two years down the road.
The right move keeps the money working, preserves the tax advantages you built, and positions the account to support your retirement income strategy efficiently. That is a very different outcome and one that is within reach with a little planning.
Your Four Options and When Each One Makes Sense
Regardless of why you are leaving, the same four options are available for your 401(k). Each has advantages and trade-offs worth understanding before you decide.
1. Roll it over to an IRA
For some people, rolling the account into an IRA is the right move. It keeps the money tax-deferred, gives you more investment flexibility and control, consolidates your retirement savings in one place, and removes the account from a former employer's plan where fees, investment options, and administrative support may not be in your best interest going forward.
A direct rollover, where the funds move directly from the 401(k) to the IRA without passing through your hands, also avoids any tax withholding and is the cleanest way to make the transition. This is where most of the planning conversation happens: what type of IRA, how it is invested, and how it fits into your broader retirement income strategy.
2. Roll it into your new employer's 401(k)
If you are moving to a new job, rolling your old 401(k) into your new employer's plan can make sense in specific situations, particularly if the new plan has strong investment options, low fees, and features like creditor protection that are important to you. It also has one advantage that an IRA does not: if you are still working past age 73, 401(k) accounts allow you to delay required minimum distributions, while IRAs do not.
The downside is that you are subject to whatever investment menu and plan rules the new employer has chosen, which may or may not serve your interests as well as a self-directed IRA would. Always evaluate the new plan carefully before consolidating into it.
3. Leave it in your former employer's plan
If you have more than $7,000 in the account, you generally have the option to leave it where it is. This can make sense if the plan has strong investment options and low institutional pricing that you would lose by rolling out. But it comes with trade-offs: you are no longer an active employee, which can mean reduced access to plan features, potential fee changes, and one more account to track and manage.
Over time, forgotten or neglected former employer accounts are one of the most common retirement planning mistakes we see. If you leave it, have a clear reason for doing so and a plan for eventually moving it.
4. Cash it out
This is almost always the wrong move, and yet it is the one many people make when they are under financial pressure or simply do not know the other options. Cashing out triggers immediate income taxes on the full balance, plus a 10% early withdrawal penalty if you are under 59 and a half. For someone with $80,000 in their 401(k), that can mean a tax bill of $25,000 or more in the year of withdrawal. The long-term cost of losing that compounding growth is even greater.
There are very limited circumstances where a cash-out makes sense, such as extreme financial hardship with no other options being the clearest case. For most people, one of the first three options is the right path. If you are considering a cash-out because you are not sure what else to do, we recommend talking to an advisor first.

How Your Situation Shapes the Decision
The four options above apply to everyone, but the right choice looks different depending on where you are in your career and what triggered the transition.
Leaving a Job Voluntarily
This is the most straightforward version of the decision. You have time to plan, you are not under financial pressure, and you can think through the options carefully. The questions to focus on are whether your new employer's plan is worth rolling into, and whether an IRA gives you more flexibility and control over your investment strategy going forward. This is also a good time to review your investment allocation. Remember, the portfolio that made sense at your last job may need adjustments as you move into a new role or closer to retirement.
Getting Laid Off
A layoff creates the same 401(k) decision under much more stressful circumstances. The immediate temptation is to cash out to cover expenses, and that is precisely the decision most likely to hurt you long term. If you are facing a gap in income, explore every other option first: severance, unemployment benefits, emergency savings, and if needed, a 401(k) loan rather than a withdrawal. The 60-day window to complete a rollover without tax consequences gives you time to make a thoughtful decision rather than a reactive one. Use it. A layoff is also a good time to talk to an advisor about how your retirement timeline may need to shift and what adjustments the plan requires.
Retiring
Retirement is where the stakes are highest, and the options are most nuanced. Your 401(k) is likely one of your largest assets, and how it moves into retirement, which account it lives in, how it is invested, and how it coordinates with Social Security and your other income sources can shape your retirement income strategy for decades. Rolling into an IRA gives you the most flexibility for tax management, Roth conversions, and withdrawal sequencing.
The Roth Conversion Opportunity Most People Miss
A job transition, particularly one that involves a gap in employment or an early retirement, can create an unexpected Roth conversion opportunity.
If you leave a job and your income drops significantly for a year or more, you may find yourself in a lower tax bracket than you have been in for years. That lower-income window is often the best possible time to convert some or all of a traditional 401(k) or IRA into a Roth account. You pay taxes on the converted amount at your current lower rate, and the money then grows tax-free and is withdrawn tax-free in retirement with no required minimum distributions on the Roth IRA.
For Iowa families, this opportunity is particularly meaningful. Iowa does not tax retirement income for residents 55 and older, which changes the federal tax math significantly. And for families near our Dubuque office in the tri-state area, the state tax treatment of a Roth conversion varies depending on whether you are in Iowa, Wisconsin, or Illinois worth understanding before you act.

What Iowa and Midwest Families Should Know
The 401(k) decision plays out a little differently here in Iowa than in much of the country and generally in your favor.
Iowa does not tax retirement income for residents 55 and older. That means once you reach 55, withdrawals from a traditional IRA or 401(k) are exempt from Iowa state income tax. For someone doing a rollover and planning their retirement income strategy, that exemption reduces the effective tax burden on distributions and makes the federal tax planning conversation even more impactful.
For families in Des Moines, West Des Moines, and across Iowa making this decision, the combination of Iowa's tax advantage, reasonable cost of living, and the right rollover strategy can make your retirement savings stretch further than national averages suggest. We work through this with clients regularly from our offices in West Des Moines and Dubuque and the numbers consistently look more favorable for Iowa families than they expect.
Frequently Asked Questions
The 401(k) decision raises questions that deserve clear answers. Below are the ones we hear most often from families across Iowa and the Midwest.
What should I do with my 401(k) when I leave a job?
In some cases, rolling the account into an IRA is the right move. It keeps the money tax-deferred, gives you more investment flexibility, and removes the account from a former employer's plan. A direct rollover avoids any tax withholding and is the cleanest way to make the transition. Before you decide, consider the other three options and whether a Roth conversion opportunity exists if your income will be lower this year than usual.
How long do I have to roll over my 401(k) after leaving a job?
If you receive a check from your former employer rather than a direct transfer, you have 60 days to deposit the funds into an IRA or new retirement account to avoid taxes and penalties. If your employer withholds 20% for taxes on an indirect rollover, you must replace that amount out of pocket to roll over the full balance. A direct rollover — where the funds transfer directly between institutions — avoids the 60-day rule and the withholding issue entirely and is the recommended approach for most people.
What happens to my 401(k) when I retire?
When you retire, your 401(k) does not automatically go anywhere; you need to make a decision about what to do with it. Generally, you have four options: roll it into an IRA, leave it in your former employer's plan, begin taking distributions directly, or a combination of these approaches. Rolling into an IRA typically provides the most flexibility for investment choices, withdrawal timing, and tax planning strategies like Roth conversions. Leaving it in your former employer's plan may make sense if the plan offers strong investment options or unique protections. Taking distributions directly is also an option, though the tax implications are worth understanding before you act. Required minimum distributions begin at age 73 regardless of which option you choose. The right path depends on your specific situation and is worth discussing with an advisor before you decide.

Traditional IRA account owners have considerations to make before performing a Roth IRA conversion. These primarily include income tax consequences on the converted amount in the year of conversion, withdrawal limitations from a Roth IRA, and income limitations for future contributions to a Roth IRA. In addition, if you are required to take a required minimum distribution (RMD) in the year you convert, you must do so before converting to a Roth IRA.
A Roth IRA offers tax deferral on any earnings in the account. Qualified withdrawals of earnings from the account are tax-free. Withdrawals of earnings prior to age 59 ½ or prior to the account being opened for 5 years, whichever is later, may result in a 10% IRS penalty tax. Limitations and restrictions may apply.
