Should You Roll a 401(k) to an IRA or Leave It? (w/Examples) + FAQs

This article reflects federal rules as of June 2026 and covers tax years 2025 and 2026. State rules vary and are noted where relevant. Tax law changes — confirm current figures before you act. This guide is educational and is not a substitute for advice from a licensed CPA, tax attorney, or fee-only financial advisor for your specific situation.

Quick Answer

It depends. For tax year 2025, roll a 401(k) to an IRA when you want lower fees, more investment choices, and simpler management. Leave it in the 401(k) when you value strong creditor protection, the Rule of 55, company stock with built-in gains, or a future backdoor Roth.

The Decision in Plain English

You just left a job, retired, or finally noticed an old 401(k) sitting with a former employer, and now you must decide what to do with that money. The wrong move can cost you thousands in taxes, a 10% penalty, lost lawsuit protection, or a blocked tax strategy — and some of those mistakes cannot be undone after 60 days.

This is one of the most common money decisions Americans face. Fidelity reports that millions of workers change jobs each year and leave retirement money behind, and the U.S. Government Accountability Office has found that billions of dollars sit in forgotten or unclaimed retirement accounts. Whoever you are and whatever your age, the goal is the same: keep the money tax-deferred, avoid penalties, and pick the home that fits your life.

Your Four Real Choices

When you leave a job, your old 401(k) does not have to move, but it can. You have four options, and each one carries its own tax result, cost, and trade-off. Picking the right one starts with knowing what each one actually does.

Option 1 — Leave it in the old 401(k). Your money stays in the former employer’s plan. It keeps growing tax-deferred, and you change nothing today. Most plans let you keep the account if your balance is above $7,000; balances of $1,000 to $7,000 may be force-rolled to an IRA by the plan, and balances under $1,000 may be cashed out to you under the IRS automatic rollover rules. The downside is you now juggle an extra account with whatever fees and limited fund menu that plan has.

Option 2 — Roll it to a Traditional IRA. You move the pre-tax money to an IRA you control at a brokerage like Fidelity, Schwab, or Vanguard. There is no tax if you do it as a direct rollover. You gain thousands of investment choices and often lower fees, but you may lose some creditor protection and certain 401(k)-only perks.

Option 3 — Roll it to your new employer’s 401(k). You consolidate the old plan into your current job’s plan. This keeps everything under one roof, preserves strong 401(k) creditor protection, and keeps the door open for a backdoor Roth. The catch is your new plan must accept rollovers, and its fund menu may be narrow.

Option 4 — Cash it out. You take the money as cash. This is almost always the worst choice before age 59½: the distribution is taxed as ordinary income and usually hit with a 10% early-withdrawal penalty under IRC Section 72(t). A $50,000 cash-out could lose $15,000 or more to taxes and penalties in a single year.

Direct vs. Indirect Rollover: The 20% Trap

How you move the money matters as much as where it goes. There are two mechanics, and one of them sets a trap that catches people every year.

A direct rollover (also called a trustee-to-trustee transfer) sends the money straight from the 401(k) to the IRA. You never touch it, no tax is withheld, and nothing is reported as income. This is the safe path, and it is the one to use almost every time.

An indirect rollover pays the money to you first, and then you have 60 days to deposit it into an IRA. Here is the trap: the plan must withhold 20% for federal taxes, even when you fully intend to roll it over, under IRS Publication 590-A. To complete a full tax-free rollover, you must replace that withheld 20% out of your own pocket within the 60 days. If you cannot, the missing 20% becomes a taxable distribution — and a penalty if you are under 59½.

Miss the 60-day deadline entirely and the whole amount becomes taxable income, plus the 10% penalty if you are under 59½. The consequence is real money: on a $100,000 indirect rollover, $20,000 is withheld, and if you do not add $20,000 from savings, that $20,000 is taxed and may carry a $2,000 penalty.

A common misconception is that the 60-day rule and the once-per-year rollover limit apply to direct rollovers. They do not — the one-rollover-per-12-months limit only applies to indirect IRA-to-IRA rollovers, not to direct trustee-to-trustee transfers. What to do: always ask for a direct rollover and have the check made payable to the new custodian “for the benefit of” you, not to you personally.

Which Situation Applies to You?

The right answer is not the same for a 26-year-old job-hopper and a 57-year-old early retiree. Find yourself below, then read the section that fits.

You are under 55 and changing jobs: an IRA or your new 401(k) both work well. Lean IRA for choice and low fees; lean new-401(k) if you earn too much for a regular Roth and want a backdoor Roth later.
You are 55 to 59½ and leaving or retiring: strongly consider leaving money in the old 401(k) to keep the Rule of 55 alive (explained below).
You hold a lot of company stock in the plan: stop before you roll anything — the NUA strategy below could save you thousands.
You are a high earner who does backdoor Roths: rolling pre-tax 401(k) money into a Traditional IRA can poison your backdoor Roth via the pro-rata rule.
You are worried about lawsuits or creditors: the 401(k) generally gives stronger protection than an IRA.

Creditor Protection: 401(k) vs. IRA

If you are a business owner, a doctor, or anyone with lawsuit risk, this section can outweigh fees and fund choice. Where your money sits changes how safe it is from creditors.

Money in a 401(k) is protected by federal ERISA law, which shields it from creditors and from bankruptcy with no dollar cap. This is among the strongest protections in the tax code, and it is why high-risk professionals often keep money in the plan.

IRAs are different. In bankruptcy, federal law (BAPCPA) protects contributory Traditional and Roth IRAs only up to an inflation-adjusted cap of $1,711,975 for the period running from April 1, 2025 through March 31, 2028. Importantly, money you rolled over from a 401(k) into an IRA is protected without regard to that dollar cap, but protection outside of bankruptcy — an ordinary lawsuit or judgment — depends entirely on your state’s law and varies widely.

The consequence is concrete: a Texas physician sued for malpractice may find a 401(k) fully shielded while an IRA’s protection hinges on state statutes. What to do: if creditor protection is a real concern, keep funds in the 401(k) or roll into the new employer’s plan, and confirm your state’s IRA protection with a local attorney before moving anything.

Protection feature	Where it stands
401(k) creditor protection	Unlimited under federal ERISA, in and out of bankruptcy
IRA bankruptcy protection	Capped at $1,711,975 (2025–2028) for contributions; rollover money uncapped
IRA protection in a lawsuit	Depends on your state — ranges from full to weak

The Rule of 55: Why Age Can Change Everything

If you are leaving a job at 55 or later, this single rule can be the deciding factor — and rolling to an IRA destroys it.

The Rule of 55 lets you take penalty-free withdrawals from your current employer’s 401(k) if you leave that job in the calendar year you turn 55 or later, per IRS guidance on early distributions. For qualified public-safety workers like police, firefighters, and air traffic controllers, the age is 50. You still owe ordinary income tax, but you skip the 10% penalty.

Here is the critical part: the rule applies only to 401(k)-type plans, not to IRAs, and only to the plan of the employer you just left. Roll that 401(k) into an IRA and you lose the Rule of 55 — now you must wait until 59½ to avoid the penalty.

A common misconception is that the Rule of 55 covers all your old 401(k)s. It does not — it only covers the plan tied to the job you separated from at 55 or later. What to do: if you retire early and may need this money before 59½, leave it in the 401(k), and roll the rest you do not need to an IRA after you turn 59½.

Net Unrealized Appreciation (NUA): The Company-Stock Move

If your 401(k) holds shares of your employer’s stock that have grown a lot, the single worst thing you can do may be a routine rollover. A special rule rewards keeping that stock out of the IRA.

Net Unrealized Appreciation (NUA) is the growth on employer stock inside your plan — the gap between what the plan paid for the shares (the cost basis) and their value today. Under IRS Notice 98-24, if you take the stock as a lump-sum, in-kind distribution after a triggering event such as separating from service, you pay ordinary income tax only on the cost basis in that year. The appreciation is then taxed at lower long-term capital gains rates whenever you sell the shares.

Roll that same stock into an IRA and you forfeit NUA forever — every dollar you later withdraw becomes ordinary income, often a much higher rate. The NUA election requires a qualifying lump-sum distribution of your entire plan balance in one tax year; the cash and other funds can still be rolled to an IRA in that same year.

The consequence can be enormous. What to do: if you hold appreciated employer stock, talk to a CPA before you move anything, because once the stock lands in an IRA the NUA election is gone for good.

Worked NUA Example

Maria retires from a manufacturer at 60 with company stock in her 401(k). The plan paid $40,000 for those shares (her cost basis), and they are now worth $200,000. The NUA is $160,000.

Using NUA, Maria takes the stock in-kind and pays ordinary income tax on only the $40,000 basis. At a 22% rate, that is $8,800 now. When she later sells the shares, the $160,000 of appreciation is taxed at the long-term capital gains rate of 15%, or $24,000 — a total of $32,800. Had she instead rolled the stock to an IRA and later withdrawn the full $200,000 at a 24% ordinary rate, she would owe $48,000. NUA saves Maria about $15,200.

The Backdoor Roth Trap: The Pro-Rata Rule

High earners who use the backdoor Roth strategy have a special reason to be careful, because rolling pre-tax 401(k) money into a Traditional IRA can wreck it.

A backdoor Roth lets people above the income limits (MAGI over $165,000 single or $246,000 married for 2025) fund a Roth indirectly. But the IRS pro-rata rule treats all your Traditional, SEP, and SIMPLE IRAs as one pool when you convert. If most of that pool is pre-tax money, most of your conversion is taxable.

The consequence: roll a $200,000 pre-tax 401(k) into a Traditional IRA, then try a $7,000 backdoor Roth, and the bulk of that $7,000 conversion becomes taxable instead of tax-free. Notably, 401(k) balances are not counted in the pro-rata math — only IRA balances are.

What to do: if you do backdoor Roths, keep pre-tax money inside a 401(k), not a Traditional IRA. If you have already created the problem, you can often fix it by rolling the pre-tax IRA money into your current employer’s 401(k) before December 31 of the conversion year.

Fees, Investment Choices, and Convenience

For most ordinary savers without lawsuit risk or company stock, this everyday category decides the matter. Small differences compound into large numbers over decades.

A 401(k) usually offers a short menu of funds chosen by the employer, and fees can be higher in small-company plans. An IRA opens the entire market — index funds, ETFs, individual stocks, and bonds — often at rock-bottom cost. Over 30 years, paying 0.30% instead of 1.00% in fees on a $200,000 balance can mean tens of thousands of extra dollars.

Convenience cuts both ways. Consolidating old 401(k)s into one IRA makes tracking and required withdrawals simpler. But a 401(k) may offer institutional share classes, stable-value funds, and a loan option that IRAs cannot match.

Three Common Scenarios

Scenario A — Young job-hopper, no special needs. Rolling to a low-cost IRA usually wins here on fees and choice.

Your move	What happens
Roll to a Traditional IRA	Lower fees, more funds, simple consolidation, no tax on a direct rollover
Leave in old 401(k)	Extra account to track, possibly higher fees, narrow fund menu

Scenario B — Early retiree at 56. The Rule of 55 makes leaving the money the strong play if you need access before 59½.

Your move	What happens
Leave in old 401(k)	Penalty-free access at 56 via Rule of 55; income tax still due
Roll to an IRA	Rule of 55 lost; 10% penalty applies until 59½

Scenario C — High-earning physician with lawsuit risk. Keeping money in a 401(k) preserves unlimited federal creditor protection.

Your move	What happens
Leave in 401(k) or roll to new 401(k)	Unlimited ERISA creditor protection; backdoor Roth stays clean
Roll to a Traditional IRA	Protection becomes state-dependent; backdoor Roth may be poisoned

Named Examples

David, 34, software engineer. David left a startup with $48,000 in its 401(k) and a clunky fund menu charging 0.95%. He does a direct rollover into a Vanguard Traditional IRA, picks a 0.04% index fund, and keeps the money tax-deferred. His goal — lower fees and one account — is met, and he owes no tax.

Susan, 57, recently laid off. Susan needs about $30,000 a year to bridge to Social Security. Because she left her employer at 57, the Rule of 55 lets her pull from that 401(k) penalty-free. She leaves the money in the plan instead of rolling it to an IRA, saving the 10% penalty she would have owed until 59½.

James, 61, longtime utility employee. James holds $250,000 of company stock with a $50,000 basis. Instead of rolling everything to an IRA, he uses the NUA strategy, pays ordinary tax on the $50,000 now, and defers the $200,000 gain to long-term capital gains rates — cutting his lifetime tax bill substantially.

Deadlines, Costs, and Timing

Timing mistakes are expensive, so put these dates on your calendar. The 60-day rule is the big one: an indirect rollover not redeposited within 60 days becomes a taxable distribution, with a 10% penalty if you are under 59½.

A direct rollover typically takes one to three weeks and costs nothing at major custodians. There is usually no fee to leave money in a 401(k) beyond the plan’s normal expenses. Cashing out is the costly choice — ordinary income tax plus a 10% penalty under IRC Section 72(t) if you are under 59½. Once you turn 73, required minimum distributions (RMDs) begin under SECURE 2.0; rolling old 401(k)s into one IRA can make RMDs easier to manage.

Mistakes to Avoid

Choosing an indirect rollover when you do not have to. The 20% withholding can trigger taxes and a penalty if you cannot replace it within 60 days.
Missing the 60-day deadline. The entire amount becomes taxable income plus a possible 10% penalty.
Rolling to an IRA before age 59½ when you may need the money. You lose the Rule of 55 and face a 10% penalty.
Rolling appreciated company stock to an IRA. You permanently forfeit NUA and convert capital gains into higher-taxed ordinary income.
Rolling pre-tax 401(k) money to a Traditional IRA while doing backdoor Roths. The pro-rata rule makes your conversions taxable.
Cashing out a small balance. A $20,000 cash-out at 35 can cost roughly $6,000 in tax and penalty and decades of lost growth.
Ignoring state creditor law. An IRA may be poorly protected from lawsuits in your state even though a 401(k) is fully shielded.
Forgetting an old 401(k) entirely. Lost accounts can be force-cashed-out or eroded by fees for years.

Do’s and Don’ts

Do’s – Do request a direct trustee-to-trustee rollover, because it avoids withholding and the 60-day risk. – Do compare fees and fund menus before moving, because small fee gaps compound into large sums. – Do check the Rule of 55 if you are 55 or older, because it can save the 10% penalty. – Do consult a CPA before touching appreciated employer stock, because NUA is lost once rolled to an IRA. – Do keep pre-tax money in a 401(k) if you do backdoor Roths, because IRAs trigger the pro-rata rule.

Don’ts – Don’t take a check made payable to you, because that forces 20% withholding. – Don’t cash out before 59½ unless you must, because taxes and the 10% penalty gut the balance. – Don’t roll to an IRA at 56 if you need early access, because you forfeit the Rule of 55. – Don’t assume your state protects IRAs from lawsuits, because protection varies widely. – Don’t ignore RMD planning at 73, because missed RMDs once carried a steep excise tax.

Pros and Cons

Rolling to an IRA — Pros – More investment choices than almost any 401(k), giving you control. – Often lower fees, which compound over decades. – Easier consolidation and simpler RMD management later. – Access to features like Roth conversions on your timeline. – One account to monitor instead of several scattered plans.

Rolling to an IRA — Cons – You lose the Rule of 55 for penalty-free access before 59½. – Weaker, state-dependent creditor protection outside bankruptcy. – You can permanently forfeit the NUA break on company stock. – Pre-tax IRA money can poison a backdoor Roth via the pro-rata rule. – No loan option, which some 401(k)s allow.

What to Do Next

Locate your 401(k) balance, fee disclosure, and fund list from the plan administrator.
Check your age and separation date against the Rule of 55 if you are 55 or older.
Look for employer stock in the plan; if present, call a CPA before moving anything to weigh NUA.
If you do backdoor Roths, plan to keep pre-tax money in a 401(k), not a Traditional IRA.
Choose your destination, then request a direct rollover with the check payable to the new custodian.
Keep Form 1099-R from the plan and report the rollover on your tax return — a direct rollover shows as non-taxable.
Call a fee-only advisor or CPA if you have company stock, lawsuit risk, a large balance, or backdoor Roth plans.

FAQs

Is rolling a 401(k) to an IRA a taxable event? No. A direct rollover of pre-tax 401(k) money to a Traditional IRA is not taxable for 2025. It stays tax-deferred. Taxes apply only if you cash out or roll pre-tax money into a Roth IRA.

How long do I have to complete a rollover? 60 days. With an indirect rollover you must redeposit the full amount, including the 20% withheld, within 60 days of receiving it, or it becomes a taxable distribution with a possible 10% penalty if you are under 59½.

Why was 20% withheld from my 401(k) check? Mandatory federal withholding. Any eligible rollover distribution paid directly to you triggers a required 20% withholding for 2025, even if you plan to roll it over. A direct trustee-to-trustee rollover avoids it entirely.

Will I lose the Rule of 55 if I roll to an IRA? Yes. The Rule of 55 applies only to 401(k)-type plans, not IRAs. Roll the money to an IRA and you must wait until age 59½ to avoid the 10% early-withdrawal penalty.

Can I roll my old 401(k) into my new employer’s plan? Yes, if the new plan accepts rollovers. This preserves unlimited ERISA creditor protection and keeps backdoor Roths clean, though the new plan’s fund menu may be limited.

What is the IRA contribution limit for 2025? $7,000, or $8,000 if you are 50 or older. Note that rollovers do not count toward this annual limit; only new contributions do.

Does rolling to an IRA hurt my backdoor Roth? Yes, it can. Pre-tax IRA money triggers the pro-rata rule, making future backdoor Roth conversions partly taxable. Keeping pre-tax money in a 401(k) avoids this because plan balances are not counted.

Are IRAs protected from creditors like 401(k)s? Not fully. 401(k)s have unlimited ERISA protection. IRA bankruptcy protection is capped at $1,711,975 for 2025–2028 on contributions, and lawsuit protection outside bankruptcy depends on your state.

What is NUA and why does it matter? Net Unrealized Appreciation. It lets you tax employer-stock growth at lower capital gains rates instead of ordinary rates, but only if you take the stock in-kind rather than rolling it to an IRA.

At what age do required withdrawals start? Age 73. Under SECURE 2.0, RMDs begin at 73 for those reaching that age in 2025. Rolling multiple old 401(k)s into one IRA can make managing these withdrawals simpler.

Should I ever cash out my 401(k) when changing jobs? Rarely. Cashing out before 59½ triggers ordinary income tax plus a 10% penalty and erases decades of tax-deferred growth. A rollover almost always beats it.

Can I split my 401(k) between options? Yes. You can leave part in the plan, roll part to an IRA, and take company stock in-kind for NUA — all in the same year, as long as each piece follows its own rules.
