When you quit a job, your 401(k) doesn’t disappear or automatically transfer anywhere. Every dollar you contributed from your paycheck stays yours, along with any vested employer match, and you generally have four choices for what happens to your 401(k) when you quit a job: leave it in the former employer’s plan, roll it into your new employer’s plan, roll it into an individual retirement account, or cash it out. Each path carries different tax consequences, and a few specific situations—an outstanding loan, company stock in the account, a small balance, a spouse—can change the calculus.
How Much of the Balance Is Actually Yours
Your own salary deferrals are always 100% yours the day you walk out. Employer contributions like matching funds and profit-sharing follow a vesting schedule set by the plan, and anything not yet vested is forfeited when you leave.
Federal law limits how slow a vesting schedule can be: cliff vesting can require up to three years of service before you own any employer contributions, and graded vesting reaches 100% no later than six years.1Office of the Law Revision Counsel. 26 USC 411 – Minimum Vesting Standards Plans can be more generous than that, and many vest immediately. Before you make any decisions, check your most recent account statement or request a Summary Plan Description from your former employer to confirm your vested balance.2Internal Revenue Service. Retirement Topics – Vesting
Leaving the Money in the Old Plan
If your vested balance is more than $7,000, the former employer cannot push you out.3Office of the Law Revision Counsel. 26 USC 411 – Minimum Vesting Standards The account keeps growing tax-deferred, and this can be a sensible holding pattern if the plan’s institutional funds are cheap or you haven’t figured out where the money should go next.
What changes is that you can no longer contribute or receive a match, and some plans charge former employees higher administrative fees. Federal law requires plan fees to be reasonable but sets no dollar cap, so read the fee disclosure before deciding to stay.4U.S. Department of Labor. A Look at 401(k) Plan Fees
Rolling the Balance Into a New Employer’s 401(k)
First, confirm the new plan accepts incoming rollovers. Most do, but it isn’t automatic. Then give the new plan’s payee name and mailing address to your old plan administrator and ask for a direct rollover. The old plan issues a check made out to the new plan “for the benefit of” you, so the money never touches your bank account.5Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
Because it’s a direct transfer, nothing is withheld and nothing is reported as taxable income for the year.6Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust If you hold Roth 401(k) contributions, those need to move into a Roth account in the new plan (or a Roth IRA) so the earnings don’t become taxable. Ask both administrators to confirm the Roth portion is tracked separately during the transfer.
Rolling the Balance Into an IRA
The same direct-rollover mechanics work with an IRA at any brokerage you choose. Open the IRA first, then hand the account details to your old plan administrator. Traditional 401(k) money goes into a traditional IRA; Roth 401(k) money goes into a Roth IRA.
You can also request an indirect rollover, where the check is made out to you. If you do, 20% is withheld upfront, and you have 60 days from receipt to deposit the full original amount into an eligible retirement account. Miss the 60 days and the whole distribution becomes taxable income, plus a 10% penalty if you’re under 59½.5Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions Direct transfers avoid all of that and are almost always the better choice.
A Note on Creditor Protection
ERISA-covered 401(k) assets have unlimited protection in bankruptcy and against most creditor claims outside bankruptcy. IRAs have a federal bankruptcy exemption capped at $1,711,975 (adjusted for inflation through 2028), and creditor protection outside of bankruptcy for IRAs varies by state. Money rolled from a 401(k) into an IRA generally keeps its original unlimited protection and doesn’t count against the IRA cap, but you’ll need to track the rollover amount carefully. If you have significant creditor exposure, that’s a point in favor of leaving the money in an employer plan.
Cashing Out and What It Costs
Taking the balance as cash is the most expensive option. On any eligible rollover distribution not sent directly to another plan, the old plan must withhold 20% for federal income tax.7Office of the Law Revision Counsel. 26 U.S. Code 3405 – Special Rules for Pensions, Annuities, and Certain Other Deferred Income On a $100,000 payout, $20,000 goes to the IRS and $80,000 arrives in your account. That 20% is a prepayment, not the final bill; your actual tax depends on your total income for the year.
If you’re under 59½, the IRS adds a 10% early withdrawal penalty on the taxable portion.8Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts On the same $100,000, that’s another $10,000. State income tax often applies too. It’s not unusual to lose a third of the balance before the money settles.
The Age-55 Exception
If you separate from service in or after the year you turn 55 (age 50 for certain public safety workers), distributions from that employer’s 401(k) are exempt from the 10% early withdrawal penalty, though ordinary income tax still applies.8Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts Rolling the money into an IRA first forfeits that exception. If you’re in that age band and expect to draw on the money before 59½, think twice before rolling out of the plan.
Other penalty exceptions include total and permanent disability, a qualified domestic relations order, and certain medical expenses.
If You Have an Outstanding 401(k) Loan
Quitting accelerates the repayment clock. Most plans require the outstanding loan balance to be repaid within 60 to 90 days of your last day. If you can’t repay in time, the balance becomes a “plan loan offset”—treated as a distribution, subject to income tax and, if you’re under 59½, the 10% penalty.
There’s a specific relief window when the offset happens because you left the job (rather than defaulting while still employed). This is a “qualified plan loan offset amount,” and you have until your tax filing deadline for that year, including extensions, to roll an equivalent amount into an IRA or another eligible plan and avoid the tax.9Internal Revenue Service. Plan Loan Offsets Leave the job in 2026 and the offset generally has to be rolled by April 15, 2027, or October 15, 2027 with an extension.10eCFR. 26 CFR 1.402(c)-2 Eligible Rollover Distributions The catch: you’ll have to fund the rollover from other savings, because the loan balance was already netted against your account.
If Your Account Holds Company Stock
Company stock inside a 401(k) opens the door to net unrealized appreciation (NUA) treatment. Rather than roll the stock into an IRA, you take a lump-sum distribution of the entire account balance and move the shares into a taxable brokerage account. You pay ordinary income tax only on the plan’s original cost basis in the shares; the appreciation that built up inside the plan is taxed at long-term capital gains rates when you eventually sell.6Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust
To qualify, the entire account balance must be distributed within a single tax year, triggered by separation from service, reaching 59½, disability, or death. Non-stock assets in the account can be rolled to an IRA in the same transaction. NUA can save meaningful tax when the stock has appreciated significantly on a low basis, but the mechanics are unforgiving. Talk to a tax professional before electing it.
Small Balances, Forced Distributions, and Spousal Consent
If your vested balance is $7,000 or less, the plan can distribute the money without your permission. SECURE 2.0 raised this threshold from $5,000, and the change is now in the tax code.3Office of the Law Revision Counsel. 26 USC 411 – Minimum Vesting Standards You must get at least 30 days’ notice of your options first, though you can waive the wait.11Internal Revenue Service. Retirement Plans FAQs Regarding Plan Terminations
- Balances from $1,001 to $7,000 can be automatically rolled into an IRA opened in your name. You can then manage it, move it, or cash it out.
- Balances of $1,000 or less can simply be mailed to you as a check. That check is taxable income, and the 10% penalty applies if you’re under 59½ unless you deposit it into an eligible retirement account within 60 days.
If you’re married, federal law may require your spouse’s written consent, witnessed by a plan representative or notary, before you can take a lump-sum distribution or name someone other than your spouse as beneficiary.12Office of the Law Revision Counsel. 26 U.S. Code 417 – Definitions and Special Rules for Purposes of Minimum Survivor Annuity Requirements Plans can waive this for balances of $7,000 or less if the plan document allows. For anything larger, missing the consent form can stop a distribution cold, so ask the plan administrator early whether it’s required.
