No, your 401k is not an IRA. They are two separate types of retirement accounts governed by different sections of the federal tax code: a 401k is an employer-sponsored plan under 26 U.S.C. § 401(k), while an Individual Retirement Account (IRA) is a personal savings arrangement under 26 U.S.C. § 408.1Office of the Law Revision Counsel. 26 USC 408 Individual Retirement Accounts Both offer tax-advantaged retirement savings, but they differ in who sets them up, how much you can contribute, how you get at the money, and how well the money is shielded from creditors.
The confusion is understandable. Both accounts grow tax-deferred, both come in traditional and Roth versions, and you can move money from one into the other. But legally and practically, they are not interchangeable.
Who Opens the Account and Who Runs It
A 401k exists because your employer sets it up. You can only contribute if your workplace sponsors a plan, contributions come out of your paycheck through payroll deduction, and the employer picks the menu of investment options you get to choose from. A plan administrator and one or more fiduciaries appointed by the employer manage the plan, and those fiduciaries have a legal duty to act solely in the interest of participants and to invest prudently.2U.S. Department of Labor. Fiduciary Responsibilities Many employers also match a portion of what you contribute, though vesting schedules can delay when you fully own those matched dollars.3Internal Revenue Service. Retirement Topics – Vesting
An IRA is yours alone. You open it directly at a bank, credit union, or brokerage firm without any employer involvement, and federal law requires a qualified trustee or custodian to hold the account.1Office of the Law Revision Counsel. 26 USC 408 Individual Retirement Accounts You need earned income to contribute, but you decide when to fund it and what to buy inside it. Choices are usually much broader than a workplace plan’s fund menu, though certain assets are off-limits: IRAs cannot hold life insurance contracts or collectibles like artwork, antiques, gems, stamps, coins, or alcoholic beverages, and buying one with IRA funds triggers a taxable distribution equal to the purchase price.
The trade-off is responsibility. In a 401k, someone else is legally on the hook for running the plan well. In an IRA, that someone is you.
How Much You Can Contribute
The contribution ceilings are one of the clearest signs these are not the same account. A 401k lets you save several times more each year than an IRA does.
For 2026, you can defer up to $24,500 of your salary into a 401k. If you are 50 or older, a catch-up contribution of $8,000 raises the total to $32,500. Under the SECURE 2.0 Act, participants aged 60 through 63 get an even higher catch-up of $11,250, allowing total deferrals of up to $35,750.4Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Employer matching contributions sit on top of these limits, pushing the combined total higher.
The 2026 IRA limit is $7,500, or $8,600 if you are 50 or older, and that cap covers your combined contributions across every traditional and Roth IRA you own.5Internal Revenue Service. Retirement Topics – IRA Contribution Limits Your contribution also cannot exceed your taxable compensation for the year.
Income can further restrict what you put into an IRA. If a workplace plan covers you, the traditional IRA deduction phases out for single filers with income between $81,000 and $91,000 in 2026, and for married couples filing jointly (contributing spouse covered) between $129,000 and $149,000. Roth IRAs phase out for single filers between $153,000 and $168,000, and for joint filers between $242,000 and $252,000.4Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Roth 401k contributions have no income limit at all.
Traditional and Roth Apply to Both
Both accounts come in traditional and Roth versions. Traditional contributions are pre-tax (or deductible for IRAs), and you pay ordinary income tax on withdrawals in retirement. Roth contributions are made with after-tax dollars, and qualified withdrawals — generally those made after age 59½ and at least five years after the first Roth contribution — come out tax-free, including all earnings.6Internal Revenue Service.

Getting to Your Money
Loans are only possible with a 401k, and only if the plan allows them. Federal law caps a 401k loan at the lesser of $50,000 or 50% of your vested balance, though some plans let you borrow up to $10,000 when half the vested balance is less than that.7Internal Revenue Service. Retirement Topics – Plan Loans You repay yourself with interest.
IRAs do not allow loans. Any money you pull out before age 59½ is a distribution, and you will owe income tax plus a likely 10% early withdrawal penalty.
The 10% early withdrawal penalty applies to both accounts, but the exceptions differ. The most notable is the Rule of 55: if you leave your job during or after the year you turn 55, you can take penalty-free withdrawals from that employer’s 401k. The exception does not apply to IRAs. For qualifying public safety employees of a state or local government, the age drops to 50.8Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
Once you hit 73, both 401k plans and traditional IRAs require you to start taking required minimum distributions (RMDs).9Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs) One useful difference: if you are still working past 73 and do not own 5% or more of the business, your current employer’s 401k can let you delay RMDs until you actually retire. Traditional IRAs give you no such option — you must start at 73 regardless of employment status.10Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs Roth IRAs, unlike Roth 401ks and traditional accounts, require no RMDs during the account owner’s lifetime.
Miss an RMD and the IRS imposes an excise tax of 25% on the shortfall, dropping to 10% if you correct the mistake within a designated correction window.11Office of the Law Revision Counsel. 26 USC 4974 Excise Tax on Certain Accumulations in Qualified Retirement Plans
Protection From Creditors
This is the difference most people overlook. A 401k benefits from ERISA’s anti-alienation rule under 26 U.S.C. § 401(a)(13), which bars creditors from assigning or seizing plan benefits.12Office of the Law Revision Counsel. 26 USC 401 Qualified Pension, Profit-Sharing, and Stock Bonus Plans The protection has no dollar cap and applies both inside and outside of bankruptcy. The main exception is a qualified domestic relations order dividing benefits in a divorce.
IRAs are also protected in bankruptcy, but with a ceiling. As of April 2025, the combined value of your traditional and Roth IRAs is protected up to $1,711,975 in federal bankruptcy, an amount adjusted for inflation every three years.13Office of the Law Revision Counsel. 11 US Code 522 – Exemptions Money you rolled over from a 401k or other qualified plan does not count against that cap and keeps unlimited protection. Outside of bankruptcy — say, in a lawsuit judgment — IRA protection depends on state law and varies widely.
Rolling a 401k Into an IRA
Moving 401k money into an IRA is common after you leave a job, and it might be what has you asking whether the two accounts are the same thing. They are not; a rollover changes which account holds the money, and some legal features change with it.
You have two ways to do it. A direct rollover sends the funds straight from your plan administrator to your IRA custodian, with no tax withholding and no risk of the money passing through your hands.14Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions An indirect (60-day) rollover sends you a check with 20% withheld for federal taxes, and you have 60 days to deposit the full original distribution amount into an IRA, replacing the withheld portion from your own pocket. Miss the deadline and the whole amount becomes taxable income, plus the 10% penalty if you are under 59½.
A direct rollover is almost always the safer choice. Just remember what changes: once the money is in an IRA, the Rule of 55 no longer applies, and the ERISA anti-alienation shield is gone. Rolled-over amounts do keep unlimited protection in federal bankruptcy, but state-law protection outside bankruptcy may be weaker than what you had under the employer plan. Consolidating old 401ks into one IRA can simplify things; weigh what you give up before you do it.
