What Happens to Your 401(k) When You Change Jobs: 4 Options

When you change jobs, your 401(k) doesn’t move automatically. You have four options for what happens to your 401(k) when you change jobs: leave the money in your former employer’s plan, roll it into your new employer’s plan, roll it into an individual retirement account, or cash it out. Every dollar you contributed from your own paycheck is yours no matter which you pick. What differs is the tax bill, the investment choices, the creditor protection, and how much of the balance actually survives the transition.

Confirm What You Actually Own

Your own contributions are 100% vested from day one. Employer contributions — matching funds, profit-sharing — follow a vesting schedule set by your plan.

Federal law allows two structures. Cliff vesting means you own nothing of the employer’s contributions until you hit a set number of years of service (up to three), at which point you jump to 100%. Graded vesting increases your ownership percentage each year over a period of two to six years.¹

Any employer contributions that aren’t vested when you leave are forfeited back to the plan. Your plan’s summary plan description spells out the schedule, so pull it before you make any moves.¹

Leave It in Your Former Employer’s Plan

If your vested balance is above $7,000, federal law lets you keep it there indefinitely, and the money continues to grow tax-deferred.²

Smaller balances get pushed out. If your vested balance is between $1,000 and $7,000 and you don’t give the plan instructions, the administrator will roll it into an IRA chosen by the plan sponsor. Under $1,000, the plan can simply mail you a check.³

Staying put preserves the strong federal creditor protections that come with an ERISA-governed plan, which generally has unlimited bankruptcy protection.⁴ The tradeoffs: you can’t make new contributions, some plans limit former employees’ investment changes or loan access, and keeping accounts scattered across old employers is how retirement savings get lost.

One point for older workers. If you’re still working past age 73, you can delay required minimum distributions from your current employer’s plan. That delay doesn’t extend to plans you left behind, which follow the standard RMD timeline.⁵

Roll It Into Your New Employer’s Plan

Moving the balance into your new plan consolidates your retirement money in one place and keeps the ERISA-level creditor protection. Not every plan accepts rollovers, and some accept only certain contribution types (pre-tax but not Roth, for example), so call the new plan administrator first.

To start the transfer, you’ll need three things from the receiving plan:

The official plan name and your participant account number.
The plan administrator’s or recordkeeper’s contact information.
A Letter of Acceptance confirming the plan will take the rollover. Most providers generate this through their online portal.

Ask for a direct rollover — the mechanics of that choice matter enough to have their own section below.

Roll It Into an IRA

An IRA rollover gives you the widest range of investments (individual stocks, bonds, ETFs, mutual funds) and full control over fees. You open the IRA with a custodian — a bank, brokerage, or other financial institution — and the account type has to match the tax treatment of your 401(k) money.

Match the Account Type to the Money

Traditional pre-tax 401(k) funds roll into a Traditional IRA. Roth 401(k) funds can only go into a Roth IRA or another designated Roth account; federal law prohibits rolling them into a Traditional IRA.⁶ If your 401(k) contains both, you may need to open two IRAs to receive each type. The IRS rollover chart confirms which accounts can receive which funds.⁷

Know the Creditor-Protection Tradeoff

ERISA-governed 401(k) plans carry virtually unlimited federal bankruptcy protection.⁴ IRAs also get federal bankruptcy protection, but standard IRA contributions are subject to an inflation-adjusted cap. Funds rolled over from a qualified employer plan into an IRA generally get unlimited bankruptcy protection separate from that cap. State-level creditor protection for IRAs outside of bankruptcy varies widely.

Cash It Out

Cashing out is the most expensive option and should generally be a last resort. Two layers of cost apply.

20% Mandatory Withholding

The plan administrator must withhold 20% of any eligible rollover distribution that’s paid directly to you rather than rolled over.⁸ On a $50,000 balance, the administrator sends $10,000 to the IRS and you receive $40,000. That 20% is a prepayment; your actual tax bill depends on your total income for the year, so you may owe more or get some back at filing.

10% Early Withdrawal Penalty

If you’re under 59½, the IRS adds a 10% penalty on the full distribution amount.⁹ The penalty is calculated on the gross amount, not the cash you actually received. On that $50,000 distribution, the penalty is $5,000 on top of ordinary income taxes. Between the two, cashing out can cost 30% to 40% or more of the balance.

The plan reports the full distribution on Form 1099-R, and you include it as income on that year’s tax return.¹⁰

The Rule of 55

One notable exception to the 10% penalty. If you leave your job during or after the calendar year you turn 55, distributions from that employer’s 401(k) plan are penalty-free.¹¹ It only applies to the plan of the employer you separated from, not to IRAs and not to plans from earlier jobs. Certain public safety employees with qualifying service may be eligible starting at age 50. You still owe regular income taxes; only the penalty is waived.

Direct vs. Indirect Rollovers

How the money physically moves matters as much as where it goes. There are two methods, and one is significantly safer.

Direct Rollover

In a direct rollover (also called a trustee-to-trustee transfer), your old plan sends the funds straight to your new plan or IRA custodian. The check is typically made payable to the receiving institution “for the benefit of” you. Because the money never passes through your hands, nothing is withheld and there’s no deadline to miss. Processing usually takes two to four weeks.

Indirect (60-Day) Rollover

In an indirect rollover, the plan sends the money to you. You then have 60 calendar days to deposit the full amount into another qualified plan or IRA.¹² Here’s the catch: even though you intend to roll it over, the administrator still withholds 20%.⁸ To complete the rollover tax-free, you have to deposit the entire original balance, including the withheld amount, using your own money to cover the gap. You get the withheld amount back when you file your return.³

Anything you don’t redeposit within 60 days is treated as a taxable distribution and may trigger the 10% penalty if you’re under 59½.¹² The 60-day clock is strict, with no automatic extension for administrative delays. Direct rollovers avoid all of this, which is why they’re almost always the better move.

If You Have an Outstanding 401(k) Loan

Borrowed against your 401(k) and still carrying a balance? Most plans require full repayment within 60 to 90 days of your departure. If you can’t pay it off, the unpaid balance is treated as a taxable distribution, and if you’re under 59½ the 10% early withdrawal penalty applies too.¹³

There’s a workaround. When the unpaid loan reduces your account balance (called a “plan loan offset”), that offset amount can be rolled over. If the offset happens because you left the job or the plan terminated, you have until your tax filing deadline for that year, including extensions, to complete the rollover and avoid taxes on the offset.¹⁴

If the loan is instead classified as a “deemed distribution” — the default happens while you’re still technically a plan participant and the account balance isn’t reduced — that amount cannot be rolled over at all.¹³ Talk to your plan administrator before your last day of work to nail down the repayment timeline and how your plan treats unpaid balances.

If Your 401(k) Holds Employer Stock

If your account contains company stock that has appreciated substantially, rolling everything into an IRA may not be your best option. A strategy called net unrealized appreciation lets you distribute the company stock to a regular taxable brokerage account. You pay ordinary income tax only on the stock’s original cost basis (what the plan paid for the shares); the appreciation is taxed at the lower long-term capital gains rate when you sell.¹⁵

Roll the same stock into a Traditional IRA and the entire value, cost basis plus all appreciation, eventually gets taxed as ordinary income when you withdraw it. The net unrealized appreciation strategy only makes sense when the stock has appreciated enough that the capital gains savings beat the immediate tax on the cost basis. It’s worth running the numbers with a tax professional before you initiate the rollover, because once the shares go into an IRA, the option is gone.
