11.3 Consequences of Prohibited Transactions: Account Disqualification, Deemed Distributions, and Excise Taxes

Dual Statutory Enforcement Paths: Owner Disqualification vs. Non-Owner Excise Taxes

The consequences of committing a prohibited transaction under Internal Revenue Code (IRC) Section 4975 depend entirely on the identity of the disqualified person involved. Congress established two starkly divergent statutory enforcement mechanisms:

1. Transactions by the IRA Owner or Beneficiary (IRC § 408(e)(2)): If the individual for whose benefit the IRA is maintained (or their designated beneficiary) participates in a prohibited transaction, the penalty is total, catastrophic account disqualification;
2. Transactions by Non-Owner Disqualified Persons (IRC § 4975(a)–(b)): If a prohibited transaction is committed by a fiduciary, custodian, broker, or service provider without the participation of the IRA owner or beneficiary, the IRA maintains its tax-exempt status, and the offending party is personally subjected to a punitive two-tier excise tax.

Total Account Disqualification under IRC § 408(e)(2)

Under IRC § 408(e)(2)(A), if an IRA owner or beneficiary engages in any transaction prohibited by IRC § 4975 with respect to their account, the statutory mandate is unequivocal: the account ceases to be an individual retirement account.

The Retroactive Disqualification Date: January 1

A critical and heavily tested technical rule is the timing of disqualification. Under IRC § 408(e)(2)(A), the account ceases to be an IRA as of the first day of the taxable year in which the prohibited transaction occurred.

• Example: An IRA owner maintains an IRA with a balance of $800,000 on January 1, 2025. On November 14, 2025, the owner borrows $10,000 from the IRA for two weeks. Although the transaction occurred in mid-November and was repaid immediately, the account ceased to be an IRA on January 1, 2025.

Mechanics of the Deemed Distribution (IRC § 408(e)(2)(B))

Under IRC § 408(e)(2)(B), upon disqualification, the account is treated as having distributed all of its assets on the first day of that taxable year (January 1) at their Fair Market Value (FMV):

1. Full Ordinary Income Inclusion: The entire fair market value of all account assets as of January 1 must be included in the IRA owner's gross taxable ordinary income for that tax year (less any documented non-deductible basis tracked on Form 8606);
2. The 10% Premature Penalty (IRC § 72(t)): If the IRA owner has not attained age 59 1/2 and does not qualify for an exception, the entire taxable deemed distribution is assessed the 10% early distribution penalty under IRC § 72(t);
3. Immediate Loss of Tax Shield: Because the account ceased to be an IRA as of January 1, all dividends, interest, rent, and capital gains realized throughout that entire calendar year and all subsequent years are fully taxable to the owner as ordinary individual income on Form 1040;
4. No Correction Window: Unlike excise tax rules, IRC § 408(e)(2) contains no statutory correction mechanism or grace period. Reversing the transaction, returning the funds, or paying back the loan does not cure the violation or resurrect the IRA.

The Single-Account Quarantine Rule

A vital safeguard for retirement savers is the single-account quarantine principle. Disqualification under IRC § 408(e)(2) applies exclusively to the specific IRA trust or custodial account that engaged in the prohibited transaction.

• If a taxpayer owns three separate accounts—Traditional IRA A ($200,000), Traditional IRA B ($500,000), and Roth IRA C ($300,000)—and executes a prohibited transaction solely within Traditional IRA A, only Traditional IRA A is disqualified.
• Traditional IRA B and Roth IRA C retain their tax-exempt status, provided assets from IRA A were not commingled or transferred into them.

Pledging IRA Assets as Collateral: IRC § 408(e)(4) vs. § 408(e)(2)

Candidates must distinguish between a general prohibited transaction and pledging an IRA as loan collateral:

Pledging an IRA Custodial Account (IRC § 408(e)(4))

If an IRA owner uses their IRA (or any portion thereof) as collateral or security for a personal loan:

• The entire account is not disqualified;
• Instead, under IRC § 408(e)(4), only the portion pledged is treated as a deemed distribution to the account owner;
• The deemed distribution occurs on the date of the pledge, is included in gross income, and is subject to the 10% Section 72(t) penalty if under age 59 1/2;
• The remaining unpledged portion of the IRA maintains its tax-deferred status.

Pledging an Individual Retirement Annuity (IRC § 408(e)(3))

In sharp contrast to custodial accounts, if an individual borrows any money under, or pledges as collateral, an individual retirement annuity contract, the contract ceases to be an individual retirement annuity under IRC § 408(e)(3). The entire fair market value of the contract is deemed distributed as of the first day of that tax year.

The IRC § 4975 Two-Tier Excise Tax for Non-Owner Disqualified Persons

When a prohibited transaction is committed by a disqualified person other than the IRA owner or beneficiary (such as an independent trustee, corporate custodian, investment manager, or broker):

• The innocent IRA owner's account is not disqualified;
• The IRA retains its tax-exempt status;
• Instead, IRC § 4975(a) and (b) impose a strict two-tier excise tax directly on the offending disqualified person.

First-Tier Excise Tax: 15% Annual Assessment (IRC § 4975(a))

An initial excise tax of 15% of the amount involved is imposed on the disqualified person for each taxable year (or partial year) in the taxable period:

• The "amount involved" is generally the greater of the amount of money and fair market value of property given, or the money and property received (for loans and leases, it is the fair market rental value or interest paid/accrued);
• The tax accrues annually until the transaction is fully corrected or the IRS issues a statutory notice of deficiency.

Second-Tier Excise Tax: 100% Punitive Assessment (IRC § 4975(b))

If the prohibited transaction is not fully corrected within the statutory taxable period (the window ending on the date the IRS mails a notice of deficiency or assesses the first-tier tax), the disqualified person is assessed a second-tier excise tax equal to 100% of the amount involved.

Reporting and Correction on IRS Form 5330

• The non-owner disqualified person must file IRS Form 5330 (Return of Excise Taxes Related to Employee Benefit Plans) and remit the excise tax;
• The excise tax must be paid from the disqualified person's personal funds; it cannot be paid or reimbursed from IRA assets;
• Statutory Correction: Correction requires placing the IRA in a financial position no worse than it would have been if the disqualified person had acted under the highest fiduciary standards, including disgorging all illicit profits and restoring lost earnings.

Prohibited Transaction Exemptions

Not every transaction between an IRA and a disqualified person is prohibited. IRC § 4975(d) lists statutory exemptions (for example, reasonable compensation paid to a disqualified person for services necessary to operate the arrangement), and the Department of Labor grants administrative class and individual exemptions. Two class exemptions matter most to bank IRA administrators, and Pub. 590-A summarizes both:

• PTE 93-1 (gifts and premiums for opening or adding to an IRA): A trustee's cash or property payment to an owner is not a prohibited transaction if it is for establishing a traditional IRA or making additional contributions, the IRA benefits only the owner, spouse, and their beneficiaries, and the total value of payments in the year is no more than $10 for deposits under $5,000 or $20 for deposits of $5,000 or more.
• PTE 93-33 (services at reduced or no cost): A bank may provide free or reduced-cost services (such as free checking) when the IRA balance counts toward the qualifying balance, provided the IRA is for the owner, spouse, and beneficiaries, the bank can legally offer the services, the services are offered on the same terms to non-IRA customers, and the IRA deposit used to qualify is not larger than the non-IRA amount another customer would need.

Fiduciaries who give investment advice for a fee, including rollover recommendations, rely on other class exemptions such as PTE 2020-02. Courts vacated the 2024 Retirement Security Rule amendments to those exemptions, and the DOL published notice of the vacatur on March 20, 2026, so the earlier versions continue to apply.

IRA Fee Administration: Permissible Direct Payments vs. Constructive Contributions

A critical operational responsibility for bank IRA specialists is auditing how account fees are settled. IRA owners frequently inquire whether they can pay account charges from outside personal funds.

1. Custodial and Administrative Fees: Permissible External Payment

Under Revenue Ruling 84-146 (trustee administrative fees billed separately and paid outside the IRA are not contributions):

• An IRA owner may pay ordinary and necessary custodial maintenance fees, annual account administration fees, setup fees, and trustee fees directly from personal non-IRA funds (such as personal checking or credit cards);
• Direct personal payment of administrative fees does not count toward the annual IRA contribution limit under IRC § 219;
• Tax Deductibility Note: Prior to 2018, IRA custodial fees paid personally could be claimed as miscellaneous itemized deductions subject to the 2% Adjusted Gross Income (AGI) floor under IRC § 212. Section 11045 of the Tax Cuts and Jobs Act of 2017 (TCJA) suspended all miscellaneous 2% itemized deductions under IRC § 67(g) for tax years 2018 through 2025, and the 2025 reconciliation law (P.L. 119-21) made that disallowance permanent. Consequently, while paying these fees externally remains completely legal and avoids depleting retirement savings, the owner cannot deduct the payment on Schedule A.

2. Brokerage Commissions and Transaction Fees: Impermissible External Payment

In contrast to administrative maintenance fees, the IRS strictly prohibits IRA owners from paying trading commissions, brokerage execution fees, sales loads, and transaction costs from personal non-IRA funds:

• Brokerage commissions are intrinsic to the acquisition or disposition cost of the underlying investment asset;
• If an IRA owner pays brokerage trading commissions or execution charges out of personal funds, the IRS treats that payment as an indirect or constructive contribution to the IRA;
• Excise Tax Penalty: If the IRA owner has already contributed their annual statutory maximum (for 2026, $7,500 plus a $1,100 catch-up), this constructive contribution creates an excess contribution under IRC § 4973;
• Excess contributions are subject to a 6% annual excise tax on IRS Form 5329 for every year the excess remains uncorrected in the account.

3. Investment Advisory and Management Fees

Wrap-fee and investment advisory fees paid to a registered investment adviser (RIA) may be paid directly by the IRA owner from personal funds only if the fee is strictly an advisory/management charge and does not bundle execution commissions. However, standard industry best practice is to debit investment advisory fees directly from the IRA to eliminate any potential IRS constructive contribution challenge.

Bank Operational Scenario: Audit Discovery, Disqualification Processing, and Form 1099-R Reporting

During an annual comprehensive risk audit of self-directed accounts, a regional bank's trust compliance team discovers an irregularity in the account of a client who maintains a $500,000 self-directed Traditional IRA. On August 18, 2025, the IRA owner wired $45,000 from the IRA into their personal business operating account to cover emergency payroll, wiring the $45,000 back into the IRA with 5% interest on October 2, 2025.

The bank's CISP operations specialist evaluates the statutory ramifications:

1. Violation Identified: Under IRC § 4975(c)(1)(B), lending money or extending credit between an IRA and the account owner (a fiduciary) is a per se prohibited transaction. Repaying the loan with interest within 45 days does not cure the violation;
2. Statutory Sanction: Under IRC § 408(e)(2), because the prohibited transaction was committed by the IRA owner, the account ceased to be an IRA on January 1, 2025;
3. Deemed Distribution Valuation: The bank's trust accounting division determines the fair market value of all assets in the IRA as of January 1, 2025, which was $480,000;
4. Tax Form Reporting: The bank is legally required to close the IRA tax status and issue a 2025 IRS Form 1099-R reporting a gross distribution of $480,000 in Box 1 and taxable amount in Box 2a. The bank enters Code 5 (Prohibited transaction), which the 1099-R instructions use to show that the account is no longer an IRA. Because the owner is 52 years old, the client also faces ordinary income tax on $480,000 plus a $48,000 early withdrawal tax (10% under IRC § 72(t)), which the client reports on Form 5329;
5. Post-Disqualification Reclassification: The bank retitles the account from "ABC Bank Custodian FBO [Client] IRA" to a taxable custodial agency account. All dividends, interest, and capital gains realized after January 1, 2025 are reported on Form 1099-DIV, 1099-INT, and 1099-B under the client's individual Social Security Number.

The specialist documents the audit file, issues written notification to the client regarding the statutory disqualification, and alerts the executive trust committee to ensure institutional compliance with IRS reporting mandates.
