When you change jobs, you have four things you can do with your 401(k) when switching jobs: leave it in the old plan, roll it into your new employer’s plan, roll it into an IRA, or cash it out. Which one is right depends on how much is vested, how old you are, whether you have a loan against the account, and whether any of the money is Roth or employer stock. Picking wrong can cost you thousands in taxes and penalties that were entirely avoidable.
Start With Your Vested Balance
Before you weigh any option, find out how much of the account is actually yours. Every dollar you contributed from your paycheck is yours from day one. Employer matching and profit-sharing dollars follow a vesting schedule, and anything unvested stays behind when you leave.1Internal Revenue Service. Retirement Topics – Vesting
Your quarterly statement or plan portal shows both a total balance and a vested balance. If you haven’t been at the company long, those two numbers can be very different. The vested balance is the one that governs everything below.
Your Four Options
Leave It in the Old Plan
If your vested balance is more than $7,000, your former employer generally can’t force you out. You can leave the money invested in the same funds indefinitely; you just can’t add to it. This is fine if the plan has low fees and decent investment options. The downsides are that you now have an account to keep track of, and some plans charge higher administrative fees to former employees.
Roll It Into Your New Employer’s Plan
If your new job’s 401(k) accepts incoming rollovers, you can consolidate everything into one place. That makes your investments easier to manage. Employer plans also carry stronger creditor protection than IRAs do in most states. You’re limited, though, to whatever investment menu the new plan offers.
Roll It Into an IRA
Moving the money to an IRA at a brokerage of your choice preserves the tax-deferred status and opens up the widest range of investments — individual stocks, bonds, ETFs, and nearly any mutual fund. That flexibility is the main draw. Before you do this, though, read the section below on the Rule of 55, because rolling into an IRA can permanently close off a penalty-free withdrawal option that only exists inside employer plans.
Cash It Out
Taking the money in cash is almost always the worst option if you’re under 59½. The whole distribution counts as ordinary income for the year, and you’ll owe a 10% early withdrawal penalty on top of that.2Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions The plan is also required by law to withhold 20% for federal taxes before it sends you the check, so you don’t even get the full amount.3Office of the Law Revision Counsel. 26 USC 3405 – Special Rules for Pensions, Annuities, and Certain Other Deferred Income On a $50,000 balance, that’s $10,000 withheld right away and potentially another $7,000 to $12,000 owed at tax time depending on your bracket. This is where most people’s retirement savings disappear during job changes.
If Your Balance Is Under $7,000
Small balances get pushed out whether you act or not. Under SECURE 2.0, effective for distributions after December 31, 2023, your former employer’s plan can force out any vested balance below $7,000.4Internal Revenue Service. 401k Resource Guide Plan Participants General Distribution Rules
- Under $1,000: the plan can cut you a check automatically. The usual taxes and penalties apply.
- $1,000 to $7,000: if you don’t say where the money should go, the plan must roll it into an IRA in your name at an institution the plan sponsor picks.
- Over $7,000: the plan needs your consent before distributing anything.
Do nothing with a small balance and you can end up with an IRA at an institution you didn’t choose, sitting in something conservative like a money market fund. Handle the rollover yourself so you control where it lands.
Ask for a Direct Rollover, Not an Indirect One
This distinction is where the expensive mistakes happen. A direct rollover means the plan sends the money straight to your new account. The check is made payable to the receiving institution “for the benefit of” you. Because you never touch the funds, nothing gets withheld and no clock starts ticking.5Internal Revenue Service. Topic No. 413, Rollovers From Retirement Plans Ask for this in almost every situation.
An indirect rollover sends the check to you. The plan withholds 20% off the top, and you then have 60 days to deposit the full original amount into a qualifying retirement account.6Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust That means you have to come up with the withheld 20% out of pocket and deposit it alongside the check you received. On a $40,000 balance, you’d receive $32,000 but need to deposit $40,000 within 60 days, covering the $8,000 gap yourself. The withheld amount comes back as a tax refund, but not in time to help.
Miss the 60-day window and the whole distribution becomes taxable, plus the 10% penalty if you’re under 59½. The IRS can waive the deadline in limited hardship cases, but counting on a waiver is not a plan.7Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
If You Have Roth Money in the Account
Roth 401(k) contributions follow different rollover rules than your pre-tax money. Roth 401(k) funds can only go to a Roth IRA or another plan’s designated Roth account. They cannot be rolled into a traditional IRA, SEP-IRA, or SIMPLE IRA.8Internal Revenue Service. Rollover Chart If your account holds both types, split the rollover and send each portion to the right kind of account.
Nontaxable amounts from a Roth 401(k) have to move through a direct trustee-to-trustee rollover. If you’re not sure which contributions are Roth and which are pre-tax, your plan statement will break it down. Getting this wrong can trigger an unexpected tax bill.
If You Have an Outstanding 401(k) Loan
If you borrowed from your 401(k) and still owe a balance when you leave, most plans require full repayment shortly after separation. If you can’t repay, the unpaid balance is treated as a distribution, so you owe income tax on it and potentially the 10% early withdrawal penalty.9Internal Revenue Service. Plan Loan Offsets
There is a way out. When a loan balance is offset because you left the job, it counts as a “qualified plan loan offset” with an extended rollover deadline. Instead of 60 days, you have until your tax filing deadline for that year, including extensions, to roll that amount into an IRA or another eligible plan.6Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust Separate in March 2026 and you’d have until October 15, 2027, if you file an extension. The catch is that you need actual cash to deposit, since the loan balance is no longer in the plan. You’re replacing money you already spent. If the alternative is a five-figure tax bill, it’s worth finding a way.
If You’re 55 or Older: Think Twice Before Rolling to an IRA
Leave your job during or after the year you turn 55, and you can take withdrawals from that employer’s 401(k) without paying the 10% early withdrawal penalty. This is the Rule of 55.2Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions You still owe ordinary income tax on the withdrawals, but the penalty goes away.
Here is the trap. The Rule of 55 only applies to the plan of the employer you separated from. The moment you roll that money into an IRA, the exception is gone. IRA withdrawals before 59½ carry the 10% penalty regardless of when you left your job. If you’re 56, just separated, and might need to touch that money before 59½, leaving it in the old 401(k) can save you a real penalty. Certain qualifying public safety workers get the same treatment starting at age 50 or after 25 years of service, whichever comes first.
If You Hold Employer Stock: Look at NUA First
Skip this section if your 401(k) doesn’t hold shares of your employer’s stock. If it does, there’s a tax move called net unrealized appreciation (NUA) worth understanding before you roll anything anywhere.
Normally, everything coming out of a pre-tax 401(k) is taxed as ordinary income. If you take a lump-sum distribution of the entire account and move the employer stock “in kind” to a regular taxable brokerage account rather than an IRA, only the stock’s original cost basis is taxed as ordinary income. The appreciation gets taxed at the long-term capital gains rate when you eventually sell. On highly appreciated stock, the savings can be substantial.
The requirements are strict: a complete distribution within a single tax year, the stock moves in kind to a taxable account, and the distribution follows a qualifying event like separation from service or reaching age 59½. Non-stock assets in the plan can be rolled to an IRA normally. This is one of the few situations where paying a tax advisor before you act is genuinely worth it, because the decision is irreversible and the dollar amounts tend to be large.
How to Actually Move the Money
Open the receiving account first. If it’s an IRA, set it up at your chosen brokerage. If it’s your new employer’s plan, confirm it accepts rollovers. Get the account number, the institution’s legal name, and the mailing address for incoming rollovers. Many institutions have a specific “for the benefit of” format they want on the check.
Then contact your old plan’s administrator through the benefits portal or the number on your statement. Ask for a direct rollover and give them the receiving account details. Some administrators need a letter of acceptance from the receiving institution; ask about this at the start so you’re not scrambling later.
The administrator will liquidate your investments and issue the transfer, usually within seven to fourteen business days. When the money lands, pick investments. The funds typically arrive in a default cash or money market position and stay there until you choose otherwise. Leaving rolled-over money in cash for months is one of the most common and costly oversights in this whole process.
The following January, your former plan will issue a Form 1099-R reporting the distribution.10Internal Revenue Service. About Form 1099-R, Distributions From Pensions, Annuities, Retirement or Profit-Sharing Plans, IRAs, Insurance Contracts, etc. If you did a direct rollover, it should show as non-taxable. Keep the paperwork in case the IRS asks.
Compare Fees Before You Move Anything
Taxes get the attention, but fees quietly cost people more over time. Employer plans often offer institutional share classes of mutual funds with lower expense ratios than the retail versions available in most IRAs. On a large balance held for a couple of decades, that gap can cost tens of thousands of dollars in lost growth.
Some older 401(k) plans, though, use expensive fund lineups or charge administrative fees to former employees that wipe out the share-class advantage. And some IRA providers offer institutional-class funds or commission-free ETFs cheaper than many employer plans. There’s no universal answer. Before you move anything, compare the specific expense ratios of the funds you’d hold in each option, check for annual account maintenance fees, and look for any surrender or transaction charges on the old plan. Five minutes with a calculator here can be worth more than any other five minutes of the process.
