What Should I Do With My 401(k) When I Change Jobs?
Last reviewed: July 2026
When you change jobs, you have four 401k rollover options: leave the money in your old plan, roll it into your new employer's plan, roll it into an IRA, or cash it out. Most people pick the IRA rollover on autopilot, and for a meaningful share of high earners that single choice quietly creates a tax problem that twenty minutes of analysis could have prevented. The right answer is situational, but the wrong answer tends to stick around for decades.
Key Takeaways
- Your four 401k rollover options at a job change are leaving it, rolling to the new plan, rolling to an IRA, or cashing out.
- Cashing out under age 59½ usually adds a 10% early withdrawal penalty on top of ordinary income tax, per the IRS.
- Rolling pre-tax 401(k) money into an IRA can trigger the pro-rata rule and complicate a clean backdoor Roth for years.
- ERISA 401(k)s carry broad federal creditor protection, while IRA bankruptcy protection is capped at $1,711,975 for 2026.
About the Author: Jeff Judge, CFP®, AEP®, ChFC®, CLU® is Managing Partner of Chesapeake Financial Planners in Forest Hill, Maryland. He has been helping families and business owners in Harford County and the Baltimore metro area navigate 401(k) rollover decisions at job changes since earning his CFP® certification in 2013, by using Chesapeake's signature process, the R.U.D.D.E.R. Method™. "The rollover notice shows up, something needs to be done with it, and people make a thirty-year decision in ten minutes," Jeff says. "That's the mistake, not which box they check."
The old 401(k) sends you a notice with four boxes to check. The form makes it feel like a paperwork chore. It isn't. The decision touches your future tax bill, your access to the money, and your legal protection, and a couple of those effects are close to permanent. Here is how to think through each option before you sign anything.
What Are My Four 401k Rollover Options When I Leave a Job?
You have exactly four choices for an old 401(k), and three of them are reasonable depending on your situation. The fourth is almost always a mistake. Here is the full menu.
- Leave it in the old employer's plan. If the plan permits it, the money stays exactly where it is, with the same investments and the same plan rules.
- Roll it into your new employer's 401(k). This consolidates the account and keeps the balance inside an employer plan.
- Roll it into an IRA. The most flexible option, with the broadest investment menu and your own custodian.
- Cash it out. Take the money now, pay the tax, and usually a penalty. Rarely the right move.
Leaving it put can be the right call when the old plan has unusually good institutional-class funds, or when you are between 55 and 59½ and may need penalty-free access. Under current IRS rules, employer plans allow penalty-free distributions as early as age 55 if you separate from service that year or later. IRAs make you wait until 59½. That two-year gap matters in your mid-50s, and it is the heart of the Rule of 55 that an IRA rollover would throw away.
Cashing out is the trap. If you are under 59½, the IRS treats the distribution as ordinary income and adds a 10% penalty. On a $150,000 balance taxed in the 32% bracket, that is roughly $63,000 surrendered to taxes and penalties before you touch a dollar. Jeff Judge often tells clients that a cash-out in your thirties is never a one-year decision. It is a six-figure decision once you count the decades of compounding you walked away from.
How Does Rolling to an IRA Affect a Backdoor Roth?
Rolling pre-tax 401(k) money into a traditional IRA can sabotage a clean backdoor Roth, because it dumps a large pre-tax balance into the same pool the IRS uses to tax conversions. This is the single most expensive oversight I see with high earners who change jobs, and almost nobody warns them about it on the rollover form.
Start with why high earners need the backdoor in the first place. Direct Roth IRA contributions phase out above certain income levels. For 2026, the IRS sets the married-filing-jointly phase-out at $242,000 to $252,000 of modified AGI, with eligibility gone entirely above the top. Plenty of dual-income households, physicians, attorneys, and tech professionals sit in or above that range. The backdoor Roth is the legal workaround: contribute to a traditional IRA on a non-deductible basis, then convert it to Roth. The 2026 traditional IRA contribution limit is $7,500, or $8,600 with the age-50 catch-up.
The pro-rata rule is where the rollover decision bites. The IRS treats all your traditional IRA money as one combined pool. If you hold $200,000 in a pre-tax IRA and add a $7,500 non-deductible contribution, only about 3.6% of any conversion counts as after-tax. The rest is taxed as ordinary income. Roll your old 401(k) into a traditional IRA and you have just stuffed that pool with pre-tax money, which can wreck a clean backdoor Roth for years.
"The clients most excited about a backdoor Roth are often the ones carrying a big rollover IRA that quietly poisons the whole strategy. The fix is usually mechanical, but only if you catch it before the money moves." Jeff Judge, CFP®, AEP®, ChFC®, CLU®
The fix is to roll the pre-tax 401(k) into your new employer's plan instead of an IRA, when the plan accepts incoming rollovers. Many modern plans do. That keeps the pre-tax balance inside the employer plan and out of the IRA pool, which preserves a clean backdoor Roth. For a high earner planning annual backdoor contributions for the next 15 to 20 years, the difference between a clean conversion and a pro-rata mess can mean tens of thousands of dollars in after-tax Roth accumulation. This is exactly the kind of sequencing the R.U.D.D.E.R. Method™, Chesapeake's six-step planning process of Review and Recognize, Uncover and Understand, Design and Develop, Discuss and Decide, Execute and Empower, and Reassess and Refine, is built to catch before anything is signed.
What About Creditor Protection and Company Stock (NUA)?
Two quieter factors can flip the rollover decision: how well each account shields you from creditors, and whether your old 401(k) holds appreciated company stock. Both surprise people because the rollover form never mentions either one.
Does an IRA protect my savings the same way a 401(k) does? Not quite. ERISA-covered employer plans, including 401(k)s, carry broad federal creditor protection regardless of balance or state. Traditional and Roth IRAs get protection in bankruptcy too, but it is capped. As of April 2025, under 11 U.S.C. §522(n), the federal bankruptcy exemption for IRAs is $1,711,975, and amounts above that can be reachable by bankruptcy creditors. Outside of bankruptcy, IRA protection depends on state law and varies widely. For most people this is theoretical. For physicians, business owners, and executives with real liability exposure whose savings approach that federal threshold, keeping the balance inside an ERISA plan preserves the broader federal shield. It is not a blanket rule: if the new plan has high-cost funds, the investment drag over 20 years can outweigh the protection, so it has to be modeled.
The other factor is Net Unrealized Appreciation, and it applies only if your old 401(k) holds employer stock that has appreciated a lot. NUA lets you take that stock out as an in-kind distribution. You pay ordinary income tax on the original cost basis, but the appreciation is taxed at long-term capital gains rates of 0%, 15%, or up to 20% when you sell, per IRS Publication 575. Roll the stock into an IRA instead and the NUA treatment is gone permanently; every future dollar comes out as ordinary income. For someone who spent 15 years at a company and watched their stock triple inside the plan, that is a costly and irreversible miss. The window closes the moment the shares hit the IRA, and most people never knew it existed.
How Does This Rollover Decision Play Out for Maryland Job-Changers?
For job-changers in Maryland, the rollover decision carries an extra tax layer national guides skip: Maryland taxes traditional 401(k) and IRA withdrawals as income, but qualified Roth distributions come out free of Maryland tax. That sharpens the case for protecting backdoor Roth access, because the Roth dollars you build now pay off twice later, at the federal level and again on your Maryland return.
There is a regional wrinkle too. Around Aberdeen Proving Ground, plenty of federal employees and contractors hold a Thrift Savings Plan alongside a private 401(k), and the TSP follows the same logic: moving it into an IRA can forfeit Rule of 55 access and complicate later Roth conversions. We see this constantly at Chesapeake Financial Planners. Based in Forest Hill, we work with families and business owners across Harford County juggling an old corporate 401(k), a new employer plan, and sometimes a government account at once, and the sequencing of those moves is where the real dollars hide.
Jeff Judge has watched local clients roll an old plan to an IRA the month before they meant to start a backdoor Roth, then spend two years untangling it. His standard move is to inventory every retirement account first, map the Maryland and federal tax effects, then decide what moves where. A rollover looks like one decision. It is really four questions stacked on top of each other.
Before the money moves, answer four questions. Do you run, or plan to run, backdoor Roth conversions? Is your total retirement balance approaching the federal IRA bankruptcy exemption while you carry liability exposure? Does the old plan hold appreciated employer stock? Are you between 55 and 59½ and likely to need early access? If you are unsure on any of them, that is the conversation worth having before you sign. For the related question of whether to leave an old plan untouched, see our guide on whether you should roll over your old 401(k) or leave it where it is.
Frequently Asked Questions
What should I do with my 401(k) when I change jobs?
Compare four options before deciding: leave the money in the old plan, roll it into your new employer's 401(k), roll it into an IRA, or cash it out. For most people, rolling to a new plan or an IRA wins on simplicity and flexibility, but high earners using a backdoor Roth often should keep pre-tax money inside an employer plan. Cashing out is almost always the most expensive choice.
Will I owe taxes if I roll over my 401(k)?
No, a direct rollover from a traditional 401(k) into a traditional IRA or another 401(k) is not taxable, because the money stays tax-deferred. Taxes apply only if you cash out, miss the 60-day window on an indirect rollover, or convert pre-tax dollars to a Roth account. With a Roth conversion, you owe ordinary income tax on the converted amount in that year.
How does rolling my 401(k) to an IRA affect a backdoor Roth?
Rolling pre-tax 401(k) money into a traditional IRA adds to the combined IRA balance the IRS uses for the pro-rata rule, which can make future backdoor Roth conversions largely taxable. Keeping that pre-tax money inside an employer 401(k) instead avoids the problem. High earners planning annual backdoor contributions should confirm whether the new plan accepts incoming rollovers first.
What is NUA and why does it matter at a job change?
Net Unrealized Appreciation lets you move appreciated company stock out of a 401(k) and pay long-term capital gains rates on the growth, instead of ordinary income tax. You pay ordinary income only on the cost basis at distribution. Rolling the stock into an IRA cancels NUA permanently, so check for appreciated employer shares before any rollover.
Is my 401(k) better protected from creditors than an IRA?
Generally yes. ERISA-covered 401(k) plans carry broad federal creditor protection regardless of balance or state. IRA protection in bankruptcy is capped at $1,711,975 for 2026, and outside bankruptcy it depends on your state's law. If you carry real liability exposure and large balances, keeping money inside an employer plan preserves the stronger federal shield.
Do Maryland taxes change my 401(k) rollover decision?
They can. Maryland taxes traditional 401(k) and IRA withdrawals as income, while qualified Roth distributions are not taxed by the state. That makes protecting clean backdoor Roth access more valuable for Maryland residents, because Roth dollars escape both federal and Maryland tax later. Federal employees near Aberdeen Proving Ground should apply the same logic to a Thrift Savings Plan.

Contributions to a traditional IRA may be tax deductible in the contribution year, with current income tax due at withdrawal. Withdrawals prior to age 59 ½ may result in a 10% IRS penalty tax in addition to current income tax.
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.
