A deemed IRA is a separate individual retirement account held inside your employer’s retirement plan, funded through payroll deduction but treated as a regular IRA for every tax purpose. It uses the administrative plumbing of your 401(k), 403(b), or similar plan, yet the contribution limits, withdrawal rules, and tax treatment are the ones that apply to any IRA you might open at a brokerage. 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
How a Deemed IRA Works
Think of the employer plan as a shell. Your contributions flow in from your paycheck the same way your 401(k) elective deferrals do, but once they land, they sit in a separate trust or custodial account and follow IRA law from that point forward. That means lower contribution limits than a 401(k), no participant loans, no qualified-plan vesting schedule, and none of the qualified-plan distribution rules.
The appeal is friction. For workers who like the idea of an IRA but never get around to opening one and funding it, a deemed IRA removes the step of setting up an outside account and remembering to transfer money. The employer plan acts as conduit and custodian; the account itself is yours in the ordinary IRA sense.
Traditional or Roth, and How Much You Can Put In
At enrollment you choose whether the deemed IRA is traditional or Roth, the same choice you would make opening an IRA on your own. Traditional contributions may be deductible, with the deduction phased out at higher incomes because contributing through a workplace plan generally makes you an active participant for deductibility purposes.2Internal Revenue Service. COLA Increases for Dollar Limitations on Benefits and Contributions Roth contributions go in after tax and are subject to the regular Roth income phase-outs: for 2026, single filers lose eligibility between $153,000 and $168,000 of modified adjusted gross income, and joint filers between $242,000 and $252,000.
For 2026, you can contribute up to $7,500 across your IRAs, or $8,600 if you’re 50 or older (the $7,500 base plus an $1,100 catch-up).3Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026; IRA Limit Increases to $7,500 That cap is the single most important number to understand about a deemed IRA, because it is shared with every other IRA you own. If you also contribute to a Roth IRA at a brokerage, the two accounts together cannot exceed the annual limit.
How Withdrawals Are Taxed
Distributions follow IRA rules, not the rules that govern your 401(k) or 403(b) balance. Traditional deemed IRA withdrawals are taxed as ordinary income. Qualified Roth deemed IRA withdrawals come out tax-free, including earnings, provided the account has been open at least five tax years and you are at least 59½, permanently disabled, or deceased (with the money going to your beneficiary).4Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Your own Roth contributions, as opposed to earnings, can come out any time without tax or penalty.
Withdrawals before 59½ generally trigger a 10% early distribution tax on top of income tax. The exceptions you can use are the IRA exceptions. That cuts both ways. In your favor: IRA owners can withdraw penalty-free for qualified higher education expenses or up to $10,000 toward a first home, neither of which a 401(k) allows.4Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Against you: the rule that lets workers who separate from service at 55 or later tap their 401(k) penalty-free does not reach the deemed IRA.
Required Minimum Distributions
RMDs for a deemed traditional IRA follow the standard IRA schedule and are calculated separately from any RMDs on your qualified plan 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 75.5Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs
A deemed Roth IRA has no lifetime RMDs, so the account can keep growing tax-free for as long as you live. Beneficiaries who inherit the account follow the inherited IRA rules after your death.
Watch for Excess Contributions
Because payroll deductions don’t talk to your outside brokerage, it’s easy to blow past the shared annual limit without noticing. Excess contributions left in the account past your tax-filing deadline, including extensions, are hit with a 6% excise tax, and the penalty repeats every year the excess remains.6Office of the Law Revision Counsel. 26 U.S. Code 4973 – Tax on Excess Contributions to Certain Tax-Favored Accounts and Annuities
To avoid the penalty entirely, pull the excess amount plus any attributable earnings out before the filing deadline. You can also recharacterize the contribution (switching Roth to traditional or the reverse) or apply it to the next year’s limit, though the 6% applies for the year the excess sat in the account.
Why You Probably Won’t Find One
Deemed IRAs have been authorized since 2003 and never caught on. Running an IRA program next to a qualified plan means separate recordkeeping, separate reporting, separate fiduciary duties, and separate trust or custodial arrangements, all for contributions capped well below what the plan already permits. Most employers decided it wasn’t worth it. If this feature matters to you, check your plan documents, but expect to open an IRA at a brokerage instead.
What Else Changes Because It’s an IRA
Three practical consequences follow from the account being an IRA rather than part of the qualified plan.
Creditor protection is weaker. Your 401(k) balance gets broad ERISA protection; a deemed IRA gets the protection any IRA gets. In bankruptcy that’s an inflation-adjusted cap, currently above $1.5 million for traditional and Roth IRA assets combined. Outside bankruptcy, protection depends on state law.
Portability works like any IRA. When you leave the employer, you can roll a deemed traditional IRA into another traditional IRA, or a deemed Roth into another Roth, at a brokerage of your choosing. You aren’t tied to the old plan.
