The disadvantages of rolling over a 401(k) to an IRA include weaker protection from lawsuits, the loss of penalty-free withdrawals available to workers who leave a job at 55 or later, no ability to borrow against the balance, the forfeiture of a valuable tax break on appreciated company stock, interference with backdoor Roth conversions, potentially higher investment fees, and a withholding trap if the transfer is handled the wrong way. An IRA gives you broader investment choices, but the move takes your savings out of a legal framework built specifically to protect employer retirement plans.
Weaker Protection From Creditors and Lawsuits
A 401(k) is shielded by a federal anti-alienation rule under the Employee Retirement Income Security Act, which bars creditors from reaching plan benefits.1Office of the Law Revision Counsel. 29 U.S. Code 1056 – Form and Payment of Benefits Because ERISA is federal, the rule works the same in every state. Lawsuits, debt collectors, and most civil judgments cannot touch the balance, with narrow exceptions for qualified domestic relations orders and certain federal tax levies.
Once the money is in an IRA, ERISA no longer applies. In a federal bankruptcy filing, amounts you originally rolled over from a qualified employer plan stay fully protected with no dollar limit. Contributions you made directly to the IRA and their earnings are capped at $1,711,975 in combined bankruptcy protection across all your IRAs.2Office of the Law Revision Counsel. 11 U.S. Code 522 – Exemptions
The bigger exposure sits outside bankruptcy. If a creditor wins a civil judgment against you for personal liability, professional negligence, or unpaid debts, your IRA’s protection depends entirely on state law. Some states fully shield traditional IRAs from civil judgments. Others protect only what a court deems necessary for your retirement support, and a few impose specific dollar caps. The same balance can be fully protected in one state and partially exposed in another. If you work in a profession with significant lawsuit risk, a 401(k) provides more predictable protection.
One nuance for self-employed savers: a solo 401(k) with no employees other than the owner may not qualify for the same broad ERISA protections that cover larger employer plans. Coverage for a solo plan depends on how it is structured and on state law.
Losing Penalty-Free Withdrawals Under the Rule of 55
If you leave your job during or after the year you turn 55, you can take money from that employer’s 401(k) without the usual 10% early withdrawal penalty.3Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Ordinary income tax still applies, but skipping the extra 10% can save thousands on a large distribution. The Rule of 55 is a safety net for people who retire early, get laid off, or otherwise stop working before 59½.
Rolling the funds into an IRA permanently closes that door. From an IRA, you generally must wait until 59½ to withdraw without a penalty.4Internal Revenue Service. Retirement Plans FAQs Regarding IRAs Distributions (Withdrawals) A 56-year-old who rolls over and then needs cash a few months later would face a 10% penalty on any IRA withdrawal, even though the same withdrawal from the 401(k) would have been penalty-free. If there is any chance you will tap retirement savings between 55 and 59½, keeping money in the 401(k) preserves that flexibility.
Public safety employees get an earlier threshold. Law enforcement officers, firefighters, corrections officers, customs and border protection officers, and air traffic controllers can take penalty-free 401(k) distributions after separating from service at age 50, provided the money comes from a governmental plan.3Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions A rollover ends that access too.
Losing the Still-Working Delay on Required Distributions
At age 73, the IRS generally requires you to start taking required minimum distributions from retirement accounts each year.5Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs If you are still working and participating in your employer’s 401(k), you can delay RMDs from that plan until the year you actually retire, provided you do not own 5% or more of the business.6Internal Revenue Service. RMD Comparison Chart (IRAs vs. Defined Contribution Plans)
Traditional IRAs have no equivalent exception. RMDs start at 73 whether or not you are still employed.5Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs Rolling into an IRA and continuing to work past 73 forces you to withdraw and pay tax on a minimum amount each year, even if you do not need the money. On a large balance, those forced distributions can push you into a higher bracket and cut into long-term tax-deferred growth.
No Loans From an IRA
Most 401(k) plans let participants borrow against the account. Federal law allows loans up to the lesser of 50% of your vested balance or $50,000, repaid through payroll deductions with interest going back into your own account.7Office of the Law Revision Counsel. 26 U.S.C. 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts Repaid on schedule, a plan loan triggers no taxes or penalties.
IRAs allow no borrowing at all. Using IRA funds as loan collateral, or attempting to borrow from the account, causes the IRS to treat the entire account as distributed. The full balance becomes taxable income for that year, plus a 10% early withdrawal penalty if you are under 59½.8Office of the Law Revision Counsel. 26 U.S.C. 408 – Individual Retirement Accounts
There is a related timing wrinkle for people with an outstanding 401(k) loan when they leave a job. Most plans require repayment by the due date of your federal tax return, including extensions, for the year the loan is treated as a distribution. Miss that, and the unpaid balance becomes taxable income.9Internal Revenue Service. Retirement Topics – Plan Loans You can offset the tax hit by rolling the unpaid loan amount into an IRA or another eligible plan before that deadline, but you would need cash from other sources to fund the rollover.
Losing the Tax Break on Appreciated Company Stock
If your 401(k) holds employer stock that has grown significantly in value, a tax strategy called Net Unrealized Appreciation (NUA) may apply. You take a lump-sum distribution of the shares into a regular taxable brokerage account and pay ordinary income tax only on the stock’s original cost basis, meaning what the shares were worth when contributed to or purchased inside the plan. The growth above that basis is taxed at long-term capital gains rates when you eventually sell, which tops out at 20% for the highest earners, plus a potential 3.8% net investment income tax.10Office of the Law Revision Counsel. 26 U.S.C. 402 – Taxability of Beneficiary of Employees Trust
NUA has strict conditions. The distribution must be a lump sum, with the entire plan balance distributed in a single tax year, and must be triggered by separation from service, reaching 59½, disability, or death.11Office of the Law Revision Counsel. 26 U.S. Code 402 – Taxability of Beneficiary of Employees Trust You can roll the non-stock portion into an IRA while sending only the company stock to a taxable account, as long as the full balance leaves the 401(k) in one tax year.
Rolling the company stock into an IRA erases the option entirely. All future IRA withdrawals are taxed as ordinary income, which can reach 37% for 2026.12Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 On $500,000 in appreciated stock with a low cost basis, the gap between 20% capital gains and 37% ordinary income on the appreciation is substantial.
Interference With Backdoor Roth Conversions
High-income savers who exceed the income limits for direct Roth IRA contributions often use a backdoor Roth: contribute to a non-deductible traditional IRA, then convert those funds to a Roth. In theory, the conversion is tax-free because the contribution was after-tax dollars. Rolling a 401(k) into a traditional IRA can make that strategy far more expensive.
The IRS applies a pro-rata rule that treats all your traditional IRA accounts as a single pool when calculating the taxable portion of a conversion. Say you have $95,000 of pre-tax rollover money in a traditional IRA and add a $5,000 non-deductible contribution. Your total IRA balance is $100,000, and 95% of it is pre-tax. Convert $5,000, and the IRS taxes 95% of it, or $4,750, no matter which dollars you meant to convert.13Office of the Law Revision Counsel. 26 U.S. Code 408 – Individual Retirement Accounts
Keeping pre-tax retirement money in a 401(k) sidesteps this because employer plans are not counted in the pro-rata calculation. Only traditional, SEP, and SIMPLE IRA balances are included. Rolling a large 401(k) into a traditional IRA can effectively shut down the backdoor Roth until the rollover money is dealt with, either by converting the entire balance and paying the tax or by rolling the pre-tax IRA money into a new employer’s 401(k) if one is available. You would also need to file Form 8606 each year to track after-tax basis in your IRAs.14Internal Revenue Service. Instructions for Form 8606
Higher Fees and Expenses
Large employer plans negotiate access to institutional-class funds with lower expense ratios than an individual can get retail. Pooled assets from thousands of employees unlock pricing tiers a single IRA holder cannot reach. The gap on the same underlying fund often runs 0.20% to 0.50% a year. On a $500,000 balance, a 0.25% fee increase adds $1,250 in annual costs, and those costs compound over decades.
Retail IRAs may also carry charges that many corporate plans do not, including annual maintenance fees and per-trade transaction costs. Some 401(k) plans absorb administrative expenses at the employer level, so participants pay nothing beyond fund expense ratios. A rollover shifts those costs to you. Compare the specific fund expense ratios and account fees in your current 401(k) against what an IRA would charge before deciding whether the added investment flexibility is worth the price.
The Withholding Trap on Indirect Rollovers
How you move the money matters as much as whether you move it. A direct rollover sends funds straight from the 401(k) administrator to the IRA custodian, and no taxes are withheld.15Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions If the plan cuts a check payable to you instead, that indirect rollover forces the administrator to withhold 20% for federal income tax, even if you intend to deposit every dollar into an IRA.
You then have 60 days to deposit the full original distribution amount, including replacing the 20% withheld, to avoid taxes and penalties.16Internal Revenue Service. Rollovers From Retirement Plans On a $100,000 distribution with $20,000 withheld, you must deposit $100,000 into the IRA within 60 days. Deposit only the $80,000 you received, and the missing $20,000 counts as a taxable distribution, subject to the 10% early withdrawal penalty if you are under 59½. You would recover the withheld amount as a tax credit when you file, but the short-term cash flow burden catches many people off guard. Request a direct rollover to avoid the problem entirely.
