Your 401(k) Does Not Move Itself
Four options for an old 401(k), and two costly mistakes people often make without realizing they made a choice.
When you leave a job, your retirement money does not move, or reinvest itself. You can leave it in the former employer’s plan, move it to a new employer’s plan, roll it into an IRA, or take a taxable distribution.
Two decisions people often make by default
Cashing out and leaving an old account unattended can both affect your long-term retirement savings, even when neither feels like an active decision.

Four options for an old 401(k)
Each option has potential advantages and disadvantages. Compare costs, investment choices, services, withdrawal rules, tax treatment, and legal protections before deciding.
Leave it in your former employer's plan
Leaving the account in your former employer's plan can be a deliberate and appropriate choice, particularly when the plan offers competitive costs or valuable features. The important distinction is whether you reviewed the option or simply forgot about the account.
Things to consider
It stays tax-deferred with no action needed, in a plan you already know, often with institutionally priced funds. If you left that job at 55 or later, the plan may allow penalty-free withdrawals an IRA would not. And there is one situation where it is clearly stronger, covered below.
What to watch
You can’t contribute anymore, you are locked to that menu, and withdrawals follow the plan's rules rather than yours. Service usually thins out once you are no longer an employee, and small balances, often under $7,000, can be pushed out automatically.
Move it to your new employer's plan
Combining retirement savings in your new employer's plan may simplify administration and preserve certain workplace-plan features. Whether it is attractive depends on the plan's costs, investment choices, services, and rules.
Things to consider
You keep contributing, you may keep access to plan loans, and you preserve the Rule of 55 for that employer. If the new plan is genuinely good, with low-cost institutional funds and a menu you would actually pick from, this is a strong option and not a consolation prize.
What to watch
Not every plan accepts incoming rollovers, and some impose a waiting period. You are back inside someone else's menu. Confirm the plan can accept and separately track Roth and after-tax dollars before you start, then put the two menus side by side. That five-minute comparison is the one almost nobody makes.
Roll it into an IRA
An IRA may provide broader investment choices, account consolidation, and access to professional advice. Compare those potential benefits with the fees, services, protections, and withdrawal features available through your employer plans.
Things to consider
A 401(k) menu is a list somebody else picked, often with a target date default quietly making the risk decision for you. An IRA lets you choose what you own, pull scattered accounts from old jobs into one place, and attach real advice to the money if you want it.
What to watch
You generally give up the Rule of 55 if you left at 55 or later and might need the money before 59½, and IRAs offer no loans. If you use a backdoor Roth, pre-tax money landing in a traditional IRA may cause a portion of future Roth conversions to be taxable under the pro-rata rule. And a rollover is two steps, not one: see below.
Take a taxable distribution
Taking a distribution provides immediate access to the money, but it may trigger mandatory withholding, ordinary income taxes, and an additional 10% federal tax if you are under age 59½ and no exception applies.
Things to consider
It puts cash in hand right away, which is the whole of its appeal. If you have an urgent need, it is worth asking whether a partial distribution solves it instead of the full balance.
What to watch
The plan withholds 20% before you see a dollar, the taxable amount is ordinary income, and an additional 10% federal tax may apply under age 59½. Then state tax. Once the rollover period has passed, the distribution generally cannot be returned through a rollover.
Whether you are working with a broker-dealer, which is paid commissions, or a registered investment adviser, which is paid fees, a firm can earn more when money moves into accounts it manages. That is worth knowing when you read anything written about rollovers, including this page.

The four options, side by side
Ten factors worth checking before you move anything. Scroll sideways on a phone.
| Decision factor | Roll to an IRA | New employer's plan | Leave it in the old plan | Cash it out |
|---|---|---|---|---|
| Stays tax-deferred | Yes, with a properly completed rollover | Yes, if the plan accepts it | Yes | No, for any taxable amount not rolled over |
| What you can invest in | Broad, varies by provider | The new plan's menu | The old plan's menu | Not applicable once it is out |
| Can you keep contributing | Yes, subject to IRA rules and limits | Yes, through payroll | No | No |
| Advice attached to the money | Yes, if you choose it | Whatever the plan offers | Often thins out once you leave | Not applicable |
| Getting money out | IRA rules, generally flexible | The new plan's rules | The old plan's rules | Immediate, after withholding |
| Loans | Not permitted | Sometimes, under plan terms | Depends on the plan | Not applicable |
| Rule of 55 | Generally lost | Tied to leaving that employer | May apply to that employer's plan | May apply if the distribution qualifies |
| Protection from creditors | Unlimited in bankruptcy for rolled-over money. Outside bankruptcy it depends on your state | Strong federal protection | Strong federal protection | Generally none once distributed |
| Costs to compare | Investment, account, platform and advisory fees | Plan and investment expenses, employer may cover some | Plan and investment expenses, employer may cover some | Taxes and any penalty |
| Required minimum distributions | IRA rules apply | Plan rules, may be delayed while still working there | Plan rules apply | Not applicable after a full distribution |

How the money moves matters
A rollover happens one of two ways. The difference decides whether taxes are withheld and whether a deadline applies, and it is where most costly mistakes happen.
Direct rollover
Trustee-to-trustee
- Your old plan sends the money straight to the receiving account (trustee-to-trustee).
- Nothing is withheld for taxes, and there is no 60-day clock to beat.
- The full eligible amount remains tax-deferred. After the transfer is completed, confirm how the money is invested in the receiving account.
Indirect rollover
Paid to you first
- The plan pays the money to you, withholding 20% for federal taxes first.
- You now have 60 days to deposit the FULL amount into another retirement account.
- To avoid tax, you must replace that withheld 20% from your own cash. The amount withheld is credited when you file your federal income-tax return, but it is not necessarily refunded.
- Miss the 60 days, or fail to replace the 20%, and the shortfall is taxed. An additional 10% federal tax may apply if you are under age 59½ and no exception applies.
A rollover involves two decisions
Step one
Move the money
Complete the rollover into the receiving retirement account.
Step two
Invest the money
A completed rollover does not necessarily mean the money is invested. Until investments are selected, some or all of the balance may remain in cash or a money market fund.
Vanguard found that many rollover investors holding cash did not know how their money was allocated. After any rollover, confirm that the account is invested consistently with your objectives, time horizon, and risk tolerance.
Make the rollover decision deliberately
Each option has different tradeoffs involving costs, investments, services, access, taxes, and legal protections. Reviewing them together can help you make an informed choice.
If you leave it, leave it on purpose
Leaving the money in your old plan can be a sound choice. Leaving it because you never got around to deciding is a different thing entirely, and it’s far more common.

If you leave the money in your former employer’s plan, review it periodically. Confirm your investments, beneficiaries, contact information, fees, and available plan features.
What cashing out could cost
The number on the check isn’t the number you keep. Withholding is a prepayment toward your tax bill, not the bill itself, and the two are constantly confused.
Still yoursGone to tax
- You start with$20,000
The full balance, before anything comes out.
- After 20% is withheld, you receive$16,000
−$4,000 withheld
The plan sends $4,000 straight to the IRS before paying you. That is a prepayment toward your tax bill, not the bill itself, and it is often not the whole bill.
- After the rest of the federal income tax, you keep$15,000
−$1,000 more tax
At a 25% federal rate the income tax on $20,000 is $5,000. The $4,000 withheld covers most of it, leaving $1,000 still owed at filing. At a higher rate you would owe more, because withholding is a flat 20% and your actual rate is not.
- After the 10% additional federal tax, you keep$13,000
−$2,000 penalty
Applies to distributions before age 59½ unless an exception fits your situation. Any state or local income tax comes out of what is left after this.
Hypothetical illustration only, for education. It assumes a fully taxable $20,000 distribution, a 25% federal income-tax rate, and that the 10% additional federal tax applies. It excludes state and local taxes, which may also be owed. Withholding is a flat 20% prepayment and is not the same as the tax you finally owe, which can be more. Your own result depends on your circumstances and on current tax law. See IRS.gov.
Taxes are only part of the potential cost. Money removed from the account also loses the opportunity for future tax-advantaged growth. Once the rollover period has passed, the distribution generally cannot be returned through a rollover. Consider whether the entire distribution is necessary and review the available alternatives first.
Rules and special situations to review before moving money
The once-per-year indirect rollover rule
- The once-per-year limit generally applies to indirect IRA-to-IRA rollovers, counted across all of your IRAs. It does not apply to rollovers from an employer plan into an IRA, to direct trustee-to-trustee transfers, or to Roth conversions. People confuse the two and trigger an excess-contribution penalty. See IRS.gov.
Matching the tax character of the money
- Pre-tax 401(k) dollars roll into a traditional IRA (or a pre-tax plan) with no tax due. Roth 401(k) dollars roll into a Roth IRA. Moving pre-tax dollars into a Roth IRA is a conversion, generally taxable in the year you do it, in exchange for tax-free qualified withdrawals later. See IRS.gov.
The pro-rata rule and backdoor Roth
- If you use (or plan to use) a backdoor Roth, rolling pre-tax plan assets into a traditional IRA may cause a portion of future Roth conversions to be taxable, because the IRS looks at all your traditional IRA dollars together (the pro-rata rule). For some people that is a reason to roll into a new employer's 401(k) instead of an IRA. This is genuinely intricate, so consider tax advice. See IRS.gov.
The Rule of 55
- If you separate from an employer in or after the year you turn 55, you can generally take penalty-free withdrawals from THAT employer's 401(k). Rolling the money into an IRA gives that up, because the exception applies to workplace plans, not IRAs. If you may need the money before 59½, the account it sits in matters. See IRS.gov.
Creditor protections differ
- Money inside a 401(k) is shielded by federal law from most creditors, in every state, whether or not you file for bankruptcy. A rollover IRA gets that same unlimited protection in bankruptcy, because the money is traced back to an employer plan. Outside bankruptcy it does not, and what protects it then depends entirely on your state. If you are facing a lawsuit or think one is coming, that difference is worth a conversation. For most people it never comes up.
RMD timing
- Once you reach the age when required minimum distributions (RMDs) begin, that year's RMD generally cannot be rolled over and must be taken first. If you are near that age, the order of operations matters. See IRS.gov for the current RMD age and rules.
Employer stock and net unrealized appreciation (NUA)
- If your 401(k) holds appreciated company stock, a net unrealized appreciation (NUA) election may let you pay long-term capital-gains rates on the growth rather than ordinary income. The rules are specific and easy to forfeit by rolling the stock into an IRA. Get professional and tax guidance before acting. See IRS.gov.
Compare the total cost, not one fee
Some employer plans provide low-cost institutional investments, while others may be more expensive. An IRA may cost less or more depending on its investments, account charges, platform costs, and advisory services.
Compare the complete cost of each option with the investments, services, planning, access, and protections you receive. Even small differences can compound over time.
FAQ
What are my options for an old 401(k)?
Four, generally: roll it into an IRA, roll it into your new employer's plan, leave it in the former plan, or cash out. Each has real tradeoffs around cost, investment choice, control, and taxes. This page explains them and does not recommend one for you.
What actually happens to most old 401(k) accounts?
A lot of them go nowhere. Capitalize, working with the Center for Retirement Research, counted 31.9 million forgotten or left-behind 401(k) accounts holding $2.13 trillion as of September 2025, with an average balance of $66,691. Separately, Vanguard reports that roughly a third of participants cash out savings when they leave a job. Both outcomes are usually the result of not deciding rather than deciding.
Is rolling my 401(k) into an IRA a good idea?
It depends on your situation, and this page will not decide it for you. An IRA generally offers the widest investment choice, consolidation, and the ability to attach advice to the money. You may give up the Rule of 55, plan loans, and simple backdoor Roth conversions, and an IRA is not automatically cheaper than a large employer plan. Compare the actual accounts available to you.
What is the difference between a direct and an indirect rollover?
In a direct (trustee-to-trustee) rollover, the money goes straight from your old plan to the receiving account and nothing is withheld. In an indirect rollover, the plan pays you first, withholding 20%, and you have 60 days to deposit the full amount, including replacing that 20% from your own cash. A direct rollover avoids the withholding and the deadline entirely. See IRS.gov.
Why was 20% withheld from my rollover check?
When an employer plan pays retirement money directly to you (an indirect rollover), it is generally required to withhold 20% for federal taxes. To complete a full rollover without owing tax, you have to deposit the entire original amount within 60 days and make up that withheld 20% from other funds, then recover it when you file. A direct rollover avoids this. See IRS.gov.
What is the 60-day rollover rule?
With an indirect rollover, the clock starts when you receive the money, and you have 60 days to deposit it into another retirement account. Miss it and the IRS generally treats it as a taxable distribution, and an additional 10% federal tax may apply if you are under age 59½ and no exception applies. Limited waivers exist. A direct rollover avoids the deadline. See IRS.gov.
Does the money get invested automatically when I roll it over?
Not necessarily, and this catches people out. A rollover is two steps: the money has to arrive, and it has to be invested. Vanguard surveyed its own rollover clients who ended up holding cash and found two thirds did not know how their assets were allocated, while 46% did not realize the money had defaulted to a money market fund. Check what your balance is actually invested in after the transfer settles.
Will I owe taxes or penalties on a rollover?
A direct rollover between like-taxed retirement accounts is generally not taxable. Cashing out is typically taxed as ordinary income, and an additional 10% federal tax may apply before age 59½ if no exception applies. Rolling pre-tax money into a Roth IRA is a conversion and is generally taxable. Tax treatment depends on your situation, so see IRS.gov. This is not tax advice.
How much do I actually lose if I cash out my 401(k)?
More than the check suggests. The plan withholds 20% up front, the taxable amount is ordinary income, and a 10% additional federal tax usually applies before age 59½. On a fully taxable $20,000 balance at a 25% federal rate with the penalty applying, roughly $13,000 would remain before any state tax. Withholding is a prepayment, not your final bill. The larger cost is that the money leaves a retirement account permanently.
Can I roll a 401(k) into a Roth IRA?
Yes, and that is a Roth conversion. Pre-tax 401(k) dollars converted to a Roth IRA are generally taxable in the year of the conversion, in exchange for tax-free qualified withdrawals later. Roth 401(k) dollars roll into a Roth IRA without a new tax bill. Whether a conversion makes sense depends on your situation. See IRS.gov.
Does rolling my 401(k) into an IRA affect a backdoor Roth?
It can. If you have pre-tax money in a traditional IRA, the pro-rata rule makes backdoor Roth conversions partly taxable, because the IRS counts all your traditional IRA dollars together. Someone who uses the backdoor Roth may prefer to roll an old 401(k) into a new employer's plan rather than into an IRA. Consider tax advice. See IRS.gov.
Is my 401(k) better protected from creditors than an IRA?
In one specific way, yes. A 401(k) is shielded by federal law from most creditors in every state, in or out of bankruptcy. A rollover IRA keeps that unlimited protection in bankruptcy because the money came from an employer plan, but outside bankruptcy it is governed by state law, which varies widely. If you are facing litigation or expect to be, that difference matters. For most people it never arises.
I left my job at 55. Does that change things?
It might. Separating from an employer in or after the year you turn 55 generally lets you take penalty-free withdrawals from that employer's 401(k), an exception that does not apply to IRAs. If you might need the money before 59½, rolling it into an IRA could forfeit that access. This is education, not a recommendation. See IRS.gov.
Are rollovers or IRAs free?
Not necessarily. IRAs and their investments can carry account, platform, advisory, and fund fees, and a plan's institutional funds are sometimes cheaper than comparable retail options in an IRA. The honest comparison is the all-in cost on both sides, and what you receive for it. Be cautious of anything described as simply free.
