What to Do With Your 401(k) When You Leave a Job
A Direct Rollover Is the Default Right Answer
For most people leaving a job, a direct rollover into an IRA or the new employer’s plan is the best move. It avoids the 20% withholding, the 60-day deadline and the 10% additional tax. Leaving the money where it is also works if the old plan is cheap. Cashing out is the one choice that reliably costs thousands.
The exceptions are narrow but real. If you leave during or after the year you turn 55, keeping the money in that plan can let you withdraw without the 10% penalty. If you have an unpaid 401(k) loan, the timing rules change too.
The Four Doors Out of an Old Plan
- ● Leave it with the old employer
- ● Roll it into the new employer plan
- ● Roll it into an IRA
- ● Cash it out
Every 401(k) gives a departing employee roughly the same four options. The differences are in tax treatment, deadlines and how much control you keep.
You can leave the account with your former employer, if the balance is above the plan’s cash-out limit. You can roll it into your new employer’s plan, if that plan accepts rollovers. You can roll it into an IRA you open yourself. Or you can take the cash.
None of the first three triggers tax when done correctly. The fourth is treated as income in the year you take it.
How the Options Compare on Cost and Flexibility
The table below uses the IRS rules in force as of October 2026. Plan fees and fund menus vary, so check your own plan documents before deciding.
| Option | Tax when you move it | Deadline | Age 55 exception kept | Best for |
|---|---|---|---|---|
| Leave it in the old plan | None | None, if above the cash-out limit | Yes | Good, cheap plan or age 55+ |
| Direct rollover to new plan | None | None | Only for the new employer once you leave it | Keeping everything in one place |
| Direct rollover to IRA | None | None | No, the exception does not apply to IRAs | Wider fund choice, lower fees |
| Indirect rollover (check to you) | 20% withheld up front | 60 days to redeposit | Depends on where it lands | Rarely the best choice |
| Cash out | Income tax plus 10% if under 59 and a half | Not applicable | Only if separated at 55+ | True emergencies only |
When Leaving It Alone Makes Sense
Doing nothing is a legitimate choice when the old plan has low-cost index funds. Large employers often negotiate institutional fund classes with lower fees than you can get alone.
There is a size limit, though. A plan may cash out small balances without your consent, and SECURE 2.0 let plans raise that limit from $5,000 to $7,000 from 2024. Balances above $1,000 that are forced out must go to an IRA automatically unless you choose otherwise.
The quiet cost of leaving accounts behind is paperwork. People who change jobs every few years can end up with four or five small plans, each with its own login and address to keep updated.
Rolling Into the New Plan or an IRA
A direct rollover means the old plan sends the money straight to the new account. The IRS confirms that nothing is withheld when the payment goes directly to another plan or IRA.
An IRA usually wins on choice. You pick the provider and can hold almost any fund, often with lower expense ratios than a small employer plan. If you are weighing account types, our guide to a Roth IRA versus a traditional IRA explains the tax trade-off.
The new employer’s plan wins on simplicity and sometimes on protection. It keeps the age 55 exception available for later, and it keeps pre-tax money out of an IRA, which matters if you ever plan a backdoor Roth contribution.
How a 60-Day Rollover Goes Wrong
- ● The plan withholds 20 percent
- ● You must replace that 20 percent yourself
- ● Miss day 60 and it becomes taxable
If the old plan sends you a check instead, it must withhold 20% for federal tax. That happens even if you tell them you will roll it over.
Here is the trap. On a $20,000 balance, you receive $16,000. To roll over the full $20,000 within 60 days, you must find the missing $4,000 from your own savings. Whatever you do not redeposit is treated as a taxable distribution.
Suppose you only redeposit the $16,000. The $4,000 gap becomes income, and if you are under 59 and a half, a 10% additional tax adds another $400. You get the withheld $4,000 back as a credit at tax time, but only after waiting months.
The IRS can waive the 60-day deadline for circumstances beyond your control. Relying on that is a poor plan when a direct rollover avoids the problem entirely.
What Cashing Out Really Costs
Cashing out feels like found money, but the tax bill arrives in stages. The plan withholds 20% immediately, and the rest of your income tax and any penalty arrive when you file.
Take the same $20,000 balance for someone under 55. The withdrawal is added to that year’s income, and a 10% additional tax of $2,000 applies on top. In a 22% bracket, total federal tax would be about $6,400, before any state tax.
That money also stops compounding. Twenty thousand dollars left invested for 25 years matters far more than the same sum spent this month.
The Age 55 Rule Changes the Math
The IRS exempts plan withdrawals from the 10% additional tax if you separate from service during or after the year you turn 55. Public safety employees in qualifying government plans get the same treatment from age 50.
This exception applies to the employer plan, not to IRAs. Roll the money into an IRA at 56 and later withdrawals before 59 and a half can face the penalty again.
So for early retirees, the order matters. Leave enough in the old plan to cover the years until 59 and a half, and roll the rest if you want lower fees.
Outstanding Loans and Partial Vesting
An unpaid 401(k) loan usually becomes due when you leave. If you cannot repay it, the plan offsets the balance against your account, which counts as a distribution.
The rollover window for a qualified plan loan offset is longer than 60 days. If the offset happens within 12 months of leaving, you have until your tax return due date, including extensions. That can stretch to October 15 of the following year, but you must use outside money to replace the offset amount. Our comparison of a 401(k) loan versus a hardship withdrawal covers how those loans work before you leave.
Check your vesting too. Employer contributions that are not yet vested stay with the plan when you go, so read what vested means in your 401(k) before choosing a leaving date.
Which Move Fits Your Situation
Changing jobs in your twenties or thirties: Direct rollover into an IRA or the new plan. Cashing out a small balance feels harmless but loses the most compounding time.
Leaving at 55 or later and planning to retire early: Keep at least part of the money in the old plan. The age 55 exception is worth more than slightly lower fees.
Old employer plan has low-cost index funds: Leaving it in place is fine. Update your contact details and note the login somewhere safe.
Unpaid loan and no cash to repay it: Expect an offset, and plan to replace that amount before your tax filing deadline. That keeps the offset from becoming taxable income.
Genuine emergency with no other savings: A partial withdrawal may be unavoidable. Take only what you need and roll the rest directly, so the 20% withholding applies to the smaller amount.
Steps for the Week You Hand In Notice
- ● Check your vested balance
- ● Ask about any outstanding loan
- ● Request a direct rollover in writing
Before your last day, log in and record your vested balance, any loan balance and the plan’s rollover form. Some plans make you call rather than click.
Open the receiving account first, whether an IRA or the new plan. Ask the old plan to pay the receiving custodian directly, and confirm the check or transfer is not made out to you personally.
Keep the final statements and the Form 1099-R you receive in January. A direct rollover still produces a 1099-R, coded to show it was not taxable.
Bottom Line on Old 401(k) Money
A direct rollover is the default answer because it keeps every dollar invested and avoids all three tax traps. Leave the money in place when the old plan is cheap or when you left at 55 or later.
Cashing out on a $20,000 balance can cost around $6,400 in federal tax alone. Treat it as the last option, not the convenient one.
FAQ
Can I leave my 401(k) with my old employer?
You can usually leave it if the balance is above your plan's cash-out limit. Since 2024 plans may set that limit as high as $7,000. Below it, the plan can pay you out or move the money into an IRA without asking.
What is the safest way to move a 401(k) after leaving a job?
Ask your old plan for a direct rollover, where the money goes straight to the IRA or new plan. Nothing is withheld and there is no 60-day deadline to meet. A check made out to you triggers 20% mandatory withholding instead.
How much tax do I pay if I cash out my 401(k) when I quit?
Expect ordinary income tax on the whole amount, plus a 10% additional tax if you are under 59 and a half and no exception applies. The plan also withholds 20% up front, which may not cover the final bill.
Does the age 55 rule matter if I roll my 401(k) into an IRA?
If you leave a job during or after the year you turn 55, withdrawals from that employer's plan avoid the 10% additional tax. The exception does not follow the money into an IRA, so rolling it over can remove the benefit.
What happens to my 401(k) loan when I leave my job?
The plan usually offsets the unpaid balance against your account, which counts as a distribution. If the offset happens within 12 months of leaving, you have until your tax return due date, including extensions, to roll that amount over.
