When you change jobs, your 401(k) stays yours, but it stops moving forward on its own. Contributions and employer matches end, and you pick from four options for the balance: leave it with the former employer, roll it into your new employer’s plan, roll it into an IRA, or cash it out. Which one fits depends on fees, investment choices, tax consequences, your age, and whether you have an outstanding loan against the account.
Check Your Vesting First
Every dollar you contributed from your own paycheck is yours the day you leave. Employer contributions through matching or profit-sharing follow a vesting schedule tied to your years of service.1Internal Revenue Service. Retirement Topics – Vesting
Federal law caps those schedules two ways. Cliff vesting gives you nothing until three years of service, when you become 100% vested at once. Graded vesting builds ownership in steps, starting at 20% after year two and reaching 100% after year six.2Internal Revenue Service. Issue Snapshot – Vesting Schedules for Matching Contributions Many plans vest faster, and some vest immediately. Anything unvested when you leave gets forfeited back to the plan. Look at your summary plan description or call HR before you make a move, so you know the actual balance you control.
Leave It with Your Former Employer
Doing nothing is a real choice. The money keeps growing tax-deferred, and you avoid paperwork and any tax hit. You give up the ability to contribute, and you now have an account to track apart from your current savings.
Small balances can be pushed out without your say-so. Under the SECURE 2.0 Act, plans can force out accounts under $7,000. Balances between $1,000 and $7,000 can be automatically rolled into an IRA on your behalf. Balances under $1,000 can be mailed to you as a check, which triggers taxes.3Internal Revenue Service. 401(k) Resource Guide – Plan Participants – General Distribution Rules Above $7,000, the plan needs your permission before distributing anything.
Watch for fees. Administrative costs your employer once covered may start coming out of your balance. Fee disclosures vary widely by plan, so review yours. Leaving small orphaned accounts scattered across old employers is a common and expensive habit over a career.
Roll It Into Your New Employer’s Plan
If your new job offers a 401(k), consolidating there keeps the money tax-deferred and puts everything in one place. Employer plans often give you access to institutional-class funds with lower expenses than a retail IRA.
Not every plan accepts incoming rollovers, and no federal rule requires them to.4Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions Ask the new plan administrator before starting. Some plans make new hires wait before rolling money in. Once the transfer lands, your balance lives inside the new plan’s investment menu and fee structure, so compare those first. A narrow, high-cost fund lineup is a reason to look elsewhere.
Roll It Into an IRA
An IRA opens up the widest range of investments: stocks, bonds, ETFs, and other holdings across any brokerage. Fees are often lower at major custodians offering commission-free index funds.
A traditional 401(k) rolled into a traditional IRA keeps its tax treatment. The money stays tax-deferred, and you owe nothing until you withdraw in retirement.5Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts
Rolling a traditional 401(k) into a Roth IRA is a different calculation. The IRS treats the converted amount as taxable income for the year you make the move, so the tax bill can be significant depending on your bracket. The trade is that qualified withdrawals from the Roth later come out tax-free. Conversions tend to make sense when you expect to be in a higher bracket in retirement, or during a low-income year such as the gap between jobs.
If you already have a Roth 401(k), rolling it into a Roth IRA is straightforward and tax-free, since both hold after-tax money. One catch: the Roth IRA’s five-year clock for tax-free earnings starts when you first contribute to any Roth IRA. If you have never held one, that clock begins with the rollover.
Creditor Protection Trade-Off
A 401(k) has strong federal creditor protection under ERISA. Creditors generally cannot reach funds inside an employer-sponsored plan.6U.S. Department of Labor. FAQs about Retirement Plans and ERISA Roll the money to an IRA and the ERISA shield no longer applies. In bankruptcy, rolled-over IRA funds still receive substantial federal protection. Outside bankruptcy, protection varies by state. Most states fully exempt IRAs from civil creditors; a handful offer limited or no protection for certain IRA types. If you have real liability exposure, weigh this before rolling out of the plan.
Cash It Out
This is almost always the worst option, and it helps to see the arithmetic. On a cash distribution, the plan withholds 20% for federal income tax before you see a dollar.3Internal Revenue Service. 401(k) Resource Guide – Plan Participants – General Distribution Rules A $50,000 account gets you a $40,000 check.
Under age 59½, the IRS adds a 10% early withdrawal penalty on the full taxable amount when you file.7Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts Add your marginal federal rate and any state tax and the total hit easily clears 30%. That $50,000 can shrink to $32,000 or less, and you permanently give up the decades of tax-deferred compounding the money would have earned.
The Rule of 55
One penalty exception is built for job changes. If you leave your employer during or after the calendar year you turn 55, you can take distributions from that employer’s 401(k) without the 10% early withdrawal penalty.8Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Regular income tax still applies, but skipping the penalty is worth thousands. The exception only covers the plan at the employer you separated from. Roll the balance into an IRA first and you lose access to it on those funds. For public safety employees of state or local governments, the age drops to 50.
If You Have an Outstanding 401(k) Loan
Leaving a job with a loan balance starts a clock. Most plans give you 60 to 90 days to repay in full. Miss it and the unpaid balance is treated as a distribution, meaning income tax on the full amount and the 10% penalty if you are under 59½.
The IRS gives more runway for what it calls a qualified plan loan offset. When the plan reduces your account balance to settle the unpaid loan, you have until your tax filing deadline for that year, including extensions, to roll the offset amount into an IRA or another eligible plan.9Internal Revenue Service. Plan Loan Offsets If your offset happens in 2026 and you file an extension, that runs to October 15, 2027. You would fund the rollover from savings or other sources, since the plan already kept the money.
Direct vs. Indirect Rollovers
The mechanics of moving the money matter. The IRS recognizes two rollover methods, and choosing the wrong one is expensive.
Direct Rollover
In a direct rollover, your old plan sends the funds straight to your new plan or IRA custodian. You never handle the money. Nothing is withheld, no 60-day deadline applies, and the IRS sees no taxable event.10Internal Revenue Service. Topic No. 413, Rollovers from Retirement Plans Contact your old plan administrator, give them the receiving account details, and the check or wire goes directly to the new custodian.
Indirect Rollover
In an indirect rollover, the plan sends the check to you. The plan must withhold 20% for federal tax first. You then have 60 days to deposit the full original amount into a new retirement account.4Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
This is where people get burned. If your account held $50,000, the check is $40,000 because $10,000 was withheld. To complete a tax-free rollover, you have to deposit $50,000 in the new account within 60 days, not $40,000. That means covering the missing $10,000 from your own pocket. You get the $10,000 back as a refund when you file, but you need the cash up front. Deposit only the $40,000 and the IRS treats the $10,000 shortfall as a taxable distribution, with the early withdrawal penalty on top if you are under 59½.4Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
Miss the 60 days entirely and the whole distribution becomes taxable income.10Internal Revenue Service. Topic No. 413, Rollovers from Retirement Plans Hardship waivers exist in limited circumstances, but relying on them is not a plan. A direct rollover avoids the whole problem.
