A deemed IRA is a separate individual retirement account held inside your employer’s retirement plan, funded through payroll deduction but treated for tax purposes as a standalone IRA rather than as part of the 401(k) or 403(b) it sits within. Internal Revenue Code Section 408(q) authorizes the arrangement and says the account “shall be treated for purposes of this title in the same manner as an individual retirement plan and not as a qualified employer plan.”1Office of the Law Revision Counsel. 26 U.S. Code 408 – Individual Retirement Accounts So the employer plan is the shell; the IRA rules do the work.
That legal distinction shapes everything else. The deemed IRA uses the IRA contribution limit rather than the 401(k) limit. It follows IRA distribution rules, IRA required minimum distribution rules, and IRA reporting. It cannot offer participant loans, and it isn’t governed by the qualified plan’s vesting schedule. The payroll-deduction convenience is the whole point: your contributions flow from your paycheck to the IRA automatically, without a separate brokerage account to open and fund on your own.
The statute reaches a broad set of workplace plans, including 401(k)s, 403(b)s, pension and profit-sharing plans, and governmental 457(b) plans.1Office of the Law Revision Counsel. 26 U.S. Code 408 – Individual Retirement Accounts Adding the feature does not put the underlying plan’s qualified status at risk.
Traditional or Roth, and What You Can Contribute
You pick at enrollment whether your deemed IRA is a traditional or Roth account, exactly the choice you would make at a brokerage. Contributions are capped at the IRA limit, not the 401(k) limit. For 2026, that means up to $7,500, plus a $1,100 catch-up if you’re 50 or older, for a total of $8,600.2Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026; IRA Limit Increases to $7,500 That cap is shared with every other IRA you own. Add up your deemed IRA payroll contributions and any deposits into an outside IRA, and the total can’t exceed the annual limit.
Roth Income Phase-Outs
A deemed Roth IRA follows the standard Roth modified adjusted gross income phase-outs. For 2026, single filers phase out between $153,000 and $168,000 of MAGI, and married couples filing jointly phase out between $242,000 and $252,000. Above the top of the range, you can’t contribute.
Traditional Deductibility
A deemed traditional IRA contribution may be deductible, but because you’re contributing through an employer plan, you’re almost certainly an “active participant” for deduction purposes, and the income-based phase-outs will apply.3Internal Revenue Service. COLA Increases for Dollar Limitations on Benefits and Contributions Nondeductible contributions still grow tax-deferred, and you track basis the same way you would for any traditional IRA.
How Distributions Work
Withdrawals follow IRA rules, not the qualified plan rules that govern the 401(k) balance sitting next door. That creates real differences in when penalty-free access is available.
Before Age 59½
Early withdrawals trigger a 10% additional tax on top of ordinary income tax, subject to the IRA list of exceptions. Some of those exceptions help you here: IRA owners can take penalty-free withdrawals for qualified higher education expenses, or up to $10,000 for a first-time home purchase, and neither is available from a 401(k).4Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Cutting the other way, the age-55 separation-from-service exception that applies to 401(k)s does not apply to a deemed IRA.
Traditional Deemed IRA Withdrawals
Distributions from a deemed traditional IRA are taxed as ordinary income at your marginal rate. If you made any nondeductible contributions, the standard IRA basis rules determine the taxable portion of each distribution.
Roth Deemed IRA Withdrawals
Qualified distributions from a deemed Roth IRA, including earnings, come out entirely tax-free. To qualify, the account must have been open for at least five tax years and you must be at least 59½, permanently disabled, or the distribution must go to your beneficiary after your death.4Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Your own Roth contributions (not earnings) can be withdrawn at any time without tax or penalty.
Required Minimum Distributions
RMDs on a deemed traditional IRA are calculated separately from anything owed on your 401(k) or 403(b) balance. If you were born between 1951 and 1959, RMDs start at age 73. If you were born in 1960 or later, they start at age 75. A deemed Roth IRA has no lifetime RMDs at all.5Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs Inherited accounts follow the usual inherited IRA rules.
Watch the Shared Contribution Limit
Because payroll deductions don’t coordinate with anything happening at your outside brokerage, over-contributing is easy if you’re funding both a deemed IRA and a personal IRA. You have to track the combined total yourself.
Excess contributions left in the account past your tax-filing deadline, including extensions, are hit with a 6% excise tax each year they remain.6Office of the Law Revision Counsel. 26 U.S. Code 4973 – Tax on Excess Contributions to Certain Tax-Favored Accounts and Annuities The 6% repeats every year the excess is still there. To avoid the penalty, withdraw the excess plus attributable earnings before the filing deadline. Recharacterizing the contribution or applying it to the next year’s limit is possible, but the 6% still applies for any year the excess sat in the account.
What’s Different From Your 401(k)
Three practical differences are worth knowing before you rely on a deemed IRA as if it were part of your workplace plan.
Creditor Protection
The broad ERISA protections that shield your 401(k) from creditors don’t extend to the deemed IRA, because it’s legally an IRA. It receives the same bankruptcy protection as any other IRA, capped at an inflation-adjusted amount currently above $1.5 million for combined traditional and Roth IRA assets. Outside bankruptcy, creditor protection depends on your state’s law.
Portability When You Leave
If you leave the employer, you can roll a deemed IRA into another IRA of the same type at any brokerage you choose, using the ordinary IRA rollover rules. You are not tied to the plan after separation.
Saver’s Credit
Deemed IRA contributions can qualify for the Retirement Savings Contributions Credit. For 2026, it’s available to married couples filing jointly with AGI up to $80,500, heads of household up to $60,375, and single filers up to $40,250.2Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026; IRA Limit Increases to $7,500 The credit reduces your tax bill by up to $1,000 (up to $2,000 for married joint filers).
Why You Probably Won’t Find One
Deemed IRAs have been available since 2003 and never caught on with employers. Running a separate IRA program alongside the qualified plan means distinct recordkeeping, distinct reporting, and separate fiduciary obligations, and for most plan sponsors that cost has outweighed the benefit. If your employer doesn’t offer the feature, opening a traditional or Roth IRA on your own at a brokerage gets you the same tax treatment and the same contribution limits. The only thing you give up is the payroll-deduction convenience.
