No, your 401(k) does not follow you from job to job automatically. When you leave an employer, the account stays put in that employer’s plan until you take action. You have four choices: leave it where it is, roll it into your new employer’s plan, roll it into an Individual Retirement Account, or cash it out and accept the taxes and penalties that come with that. Which one fits depends on your balance, your vesting status, and whether the new plan will accept a transfer in.
If You Do Nothing, the Money Stays Behind
After you leave, your old 401(k) keeps operating under the former employer’s plan rules and investment lineup. You can generally leave it there as long as your vested balance is more than $7,000.1Office of the Law Revision Counsel. 26 USC 411 – Minimum Vesting Standards That threshold was $5,000 before 2024, when the SECURE 2.0 Act raised it. Fall below $7,000 and the plan can force a distribution without asking you. If you don’t direct that money into another retirement account in time, it becomes taxable, and you can be hit with an early withdrawal penalty on top.
Leaving the money in place is not automatically a bad choice. Your investments keep growing tax-deferred and the fund lineup stays the same. But you can no longer contribute, and some plans charge former employees higher recordkeeping or administrative fees than active workers pay.2U.S. Department of Labor. Understanding Retirement Plan Fees and Expenses On a smaller balance, those fees quietly eat into your return.
Confirm What’s Actually Yours First
Before you move anything, find out how much of the balance you can actually take. Every dollar you contributed from your own paycheck is 100% yours from day one. Employer contributions like matching funds vest on a schedule set by the plan.3Internal Revenue Service. Retirement Topics – Vesting Leave before you’re fully vested and you forfeit the unvested portion.
Federal law permits two vesting schedules for employer contributions to a defined contribution plan like a 401(k):3Internal Revenue Service. Retirement Topics – Vesting
- Cliff vesting: you own none of the employer contributions until you complete three years of service, then jump to 100% at once.
- Graded vesting: you earn 20% after two years and another 20% each year until you’re fully vested after six years.
Your plan’s Summary Plan Description says which schedule applies. If you’re close to a milestone, the timing of your departure can be worth thousands.
Rolling Into Your New Employer’s Plan
If your new job offers a 401(k) or another qualified plan, you may be able to move your old balance directly into it. Consolidating keeps your retirement savings in one place and can give you access to institutional-class funds with lower fees. Federal law does not require an employer to accept incoming rollovers, though.4Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust Check the new plan’s Summary Plan Description or ask the administrator before you start.
The transfer moves between qualified plans, so the money keeps its tax-deferred status and isn’t treated as taxable income.5eCFR. 26 CFR 1.402(c)-2 – Eligible Rollover Distributions If your old 401(k) holds both pre-tax and after-tax contributions, any distribution takes a proportional share of each. IRS guidance lets you split it: send the pre-tax portion to the new plan or a traditional IRA and the after-tax portion to a Roth IRA, as long as both transfers happen at the same time.6Internal Revenue Service. Rollovers of After-Tax Contributions in Retirement Plans
Rolling Into an IRA
An IRA rollover gives you full control over investments and typically a much wider selection than an employer plan offers. You’ll choose between a traditional IRA and a Roth IRA, and the tax consequences differ.
Traditional IRA
Rolling pre-tax 401(k) money into a traditional IRA preserves the tax deferral. No tax is due at the time of the transfer, and the funds keep growing untaxed until you take withdrawals in retirement.4Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust
Roth IRA Conversion
Moving pre-tax 401(k) funds into a Roth IRA is a conversion. The entire converted amount is included in your gross income for the year, and you’ll owe income tax on it. In exchange, qualified withdrawals in retirement come out tax-free. The 10% early withdrawal penalty does not apply to a Roth conversion, even if you’re under 59½.7Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs If you already have a designated Roth 401(k), those dollars roll into a Roth IRA without additional tax, because the contributions were already after-tax.
Two Factors That Change the IRA Math
Required minimum distributions work differently. If you’re 73 or older and still working, keeping money in your current employer’s 401(k) lets you delay RMDs on that plan until the year you actually retire, provided you don’t own 5% or more of the business.8Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs That still-working exception does not exist for IRAs; once you hit 73, you must start taking distributions from a traditional IRA whether you’re working or not.
Creditor protection also shifts. Assets in an employer-sponsored plan covered by ERISA have unlimited federal protection from creditors and bankruptcy claims. IRAs are protected in bankruptcy only up to an inflation-adjusted cap, currently $1,711,975 as of April 2025.9Office of the Law Revision Counsel. 11 USC 522 – Exemptions Outside bankruptcy, IRA protection from lawsuits and judgments depends on your state and varies widely. If asset protection matters to you, an employer plan tends to offer stronger coverage.
Direct vs. Indirect Rollover
How the money moves matters as much as where it goes. There are two mechanics, with very different tax exposure.
Direct Rollover
In a direct rollover, the former plan administrator sends the funds straight to the new account. The check is made payable to the new custodian “for the benefit of” you, and the money never touches your bank account. Nothing is withheld and there is no deadline risk.10Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions Federal law requires every qualified plan to offer this option.11Office of the Law Revision Counsel. 26 USC 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans
Indirect (60-Day) Rollover
In an indirect rollover, the check comes to you. Your former employer must withhold 20% of the taxable amount for federal income tax before cutting it.12Office of the Law Revision Counsel. 26 USC 3405 – Special Rules for Pensions, Annuities, and Certain Other Deferred Income You then have 60 days from the date you receive the money to deposit the full original amount into a new qualified plan or IRA.13Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust To replace the withheld 20% and make yourself whole, you’ll have to use other cash. You claim the withholding back as a credit when you file your return.
Miss the 60 days and the whole distribution turns into taxable income. If you’re under 59½, add a 10% early withdrawal penalty.14Office of the Law Revision Counsel. 26 USC 72 – Annuities, Certain Proceeds of Endowment and Life Insurance Contracts The IRS allows self-certification to waive the deadline in narrow circumstances such as serious illness, a financial institution error, or a natural disaster.15Internal Revenue Service. Revenue Procedure 2020-46 Direct rollovers avoid all of this, which is why they’re the standard recommendation.
Partial Rollovers
You aren’t locked in to moving everything. Federal rules let you roll over all or part of an eligible distribution and keep the rest as cash.10Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions Whatever you keep is ordinary income, and the 10% early withdrawal penalty can apply if you’re under 59½.
If You Have an Outstanding 401(k) Loan
An outstanding loan against your 401(k) complicates things when you leave. The plan can require you to repay the full balance, and if you can’t, the unpaid amount is treated as a distribution, reported to the IRS as taxable income, and potentially hit with the 10% penalty if you’re under 59½.16Internal Revenue Service. Retirement Topics – Plan Loans
You can head off those consequences by rolling an amount equal to the unpaid loan into an IRA or another eligible plan. The deadline depends on the type of offset. For a qualified plan loan offset, meaning the loan becomes a distribution specifically because you left the job or the plan terminated, you have until your federal tax filing deadline, including extensions, to complete the rollover.17Internal Revenue Service. Plan Loan Offsets With an extension, that runs to mid-October of the following year. A general plan loan offset falls under the ordinary 60-day rollover window.
How to Start the Rollover
Once you’ve decided where the money is going, contact the plan administrator on your most recent 401(k) statement and request the distribution paperwork. Before you send it back, open and confirm the receiving account at the new employer’s plan or IRA custodian, and gather the new account number, the custodian’s mailing address, and any routing information the old plan needs.
For a direct rollover, the check is written to the new custodian “for the benefit of” you, formatted like “Fidelity Investments FBO Jane Smith.” That payee line is what keeps the transfer tax-free.10Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions Many custodians now handle direct rollovers electronically, shortening the process from weeks to days.
Your former plan administrator also has to send you a written notice before releasing any eligible rollover distribution. It explains your right to a direct rollover, the withholding that applies if you take the money in hand, and the 60-day window.4Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust Read it before you sign anything. It confirms exactly how your specific distribution will be taxed.
