A checkbook IRA hands you direct control of retirement money through an LLC, and the problems with a checkbook IRA all trace back to that control: one prohibited transaction, one commingled payment, or one missed filing can strip the entire account of its tax-advantaged status as of January 1 of that year. The IRS then treats every dollar in the account as distributed to you, taxable at ordinary rates, with a 10 percent early withdrawal penalty on top if you’re under 59½.1Internal Revenue Service. Topic No. 557, Additional Tax on Early Distributions From Traditional and Roth IRAs There’s no partial penalty, no fine limited to the bad transaction. The whole account goes.
Prohibited Transactions Can Destroy the Account
Federal tax law bars certain dealings between your IRA (including any LLC it owns) and you or anyone closely connected to you. The rules target self-dealing, where retirement money benefits someone now rather than growing for retirement. Common violations include lending IRA funds to yourself, staying overnight at IRA-owned real estate, and paying yourself a salary or management fee for running the LLC.2Internal Revenue Service. Retirement Topics – Prohibited Transactions
If you commit a prohibited transaction, the account stops being an IRA on January 1 of that year. The IRS treats the full balance as distributed to you on that date, at fair market value.3Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts Someone with $400,000 in a checkbook IRA who slips up once could face a six-figure tax bill in a single year. It is the complete loss of tax-deferred status on every dollar, and it is not reversible.
The Sweat Equity Problem With Real Estate
If your IRA LLC owns a rental property, you cannot perform physical work on it. No painting, no mowing, no fixing a leaky faucet, no bathroom renovation. The IRS treats your labor as a non-cash contribution to the IRA from a disqualified person, which is a prohibited transaction with all the consequences above.
The dividing line runs between desk work and physical work. Paperwork, hiring contractors, negotiating leases, and managing LLC finances are all fine. Picking up a paintbrush is not. Many investors set up a checkbook IRA specifically to buy rental property and learn this rule only after they’ve already started fixing up a house. Every repair, improvement, and bit of routine maintenance on IRA-owned property has to be outsourced to unrelated third parties.
Who Counts as a Disqualified Person
Prohibited transactions aren’t limited to what you do personally. They cover a defined circle of people, and the IRA cannot transact with any of them regardless of whether the deal is fair.
- You, the IRA owner, and your beneficiaries
- Your spouse
- Your parents and grandparents
- Your children, grandchildren, and their spouses
- Any fiduciary of the IRA, including the custodian
- Any entity where you and other disqualified persons collectively hold 50 percent or more ownership
Family ownership percentages combine. If you own 30 percent of a company and your daughter owns 25 percent, the company is disqualified because the family stake exceeds 50 percent.2Internal Revenue Service. Retirement Topics – Prohibited Transactions
Indirect benefits trigger the rules just as directly. Your IRA cannot buy a house your son plans to rent, even at full market rate. It cannot hire your spouse’s contracting business to renovate an investment property, even if her bid comes in lowest. It cannot be used as collateral for a personal loan. If a disqualified person is anywhere in the transaction, it’s a violation, whether or not anyone actually benefited.4Office of the Law Revision Counsel. 26 USC 4975 – Tax on Prohibited Transactions
Commingling Personal and LLC Money
The LLC bank account has to operate as a completely separate financial life from your personal accounts. This is where small mistakes snowball. Using a personal credit card to cover a repair on IRA-owned property, planning to reimburse yourself later, is a commingling event. Depositing personal funds into the LLC account, even briefly, looks like an excess contribution. Paying a personal bill from the LLC checkbook looks like a distribution.
Intent doesn’t help you. Once personal and plan money mix, the IRS can argue the account is no longer a legitimate retirement vehicle, and the result is the same disqualification and deemed distribution that follows any other prohibited transaction. If an IRA-owned property needs an emergency repair and the LLC doesn’t have enough cash, the only compliant path is to make a regular IRA contribution within annual limits and let the LLC pay from its own funds.
Unexpected Tax Bills From UBTI and Debt-Financed Income
IRAs are generally tax-exempt, but the exemption has limits. When your IRA LLC earns income from an active trade or business rather than passive investments, that income is subject to unrelated business income tax. Running a restaurant, operating a retail business, or flipping houses through your IRA LLC can all generate this tax.5Office of the Law Revision Counsel. 26 USC 512 – Unrelated Business Taxable Income
A related trap hits investors who borrow to buy property. When the LLC takes out a mortgage, a portion of the rental income and any eventual sale proceeds become unrelated debt-financed income, taxed in proportion to the debt used to acquire the property.6Office of the Law Revision Counsel. 26 USC 514 – Unrelated Debt-Financed Income Many real estate investors assume their IRA’s tax-exempt status shelters all rental income. It doesn’t.
Both types of income are taxed at trust rates, which hit 37 percent at just $16,000 of taxable income in 2026.7Internal Revenue Service. 2026 Form 1041-ES – Estimated Income Tax for Estates and Trusts Even modest business income or leveraged rental income can end up at the top rate. The IRA must file Form 990-T and pay the tax from retirement funds whenever gross unrelated business income reaches $1,000 in a year.8Internal Revenue Service. Unrelated Business Income Tax
Required Minimum Distributions Meet Illiquid Assets
A traditional checkbook IRA follows the same required minimum distribution rules as any other traditional IRA. Starting at age 73, you have to withdraw a calculated amount each year, and the IRS makes no exception for illiquid assets. If your LLC holds a rental property and a small stake in a private company, you still have to produce the cash.
You can’t easily carve off 4 percent of a rental house. The options are to sell (possibly at a bad time or a discount), distribute the property in-kind with a current appraisal, or keep enough liquid cash in the LLC to cover annual distributions. Investors focused on acquiring assets often forget to build a cash reserve for future RMDs.
Missing an RMD carries a 25 percent excise tax on the amount you should have withdrawn. Correct the mistake within two years and the penalty drops to 10 percent.9Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs Either way, it’s a steep price for a liquidity problem you could have seen coming.
Annual Valuations Are Your Job
Every checkbook IRA owner has to provide an accurate fair market value for all LLC assets as of December 31 each year. The custodian needs this number to file Form 5498, which reports account value and contribution activity to the IRS.10Internal Revenue Service. Form 5498 – IRA Contribution Information A brokerage account updates automatically. Here the burden of producing a defensible valuation is on you.
The valuation has to come from a qualified, independent third party: a licensed real estate professional, a certified appraiser, a CPA, an independent valuation firm, or a county property tax assessment. The valuer cannot be a disqualified person. If the valuation carries a fee, the IRA itself must pay it, because paying from personal funds creates a commingling problem.
Understating values creates its own risks. It can make the IRA appear within contribution or distribution limits when it isn’t, and if the IRS decides the valuation was deliberately deflated, an audit and penalties can follow. This is an annual obligation for the life of the account, and for private business interests or undeveloped land, reliable valuations are both expensive and slow.
Setup and Ongoing Costs
A checkbook IRA costs more to establish and maintain than a conventional IRA. At minimum you need to form an LLC (state filing fees typically $70 to $400), draft an operating agreement with IRS-compliant language on prohibited transactions and disqualified persons, and pay a self-directed IRA custodian’s annual fee. Attorney fees for the operating agreement average around $790. Annual state fees and franchise taxes to keep the LLC in good standing can add several hundred dollars a year depending on the state.
The administrative time is the bigger cost. You maintain the LLC’s books, arrange annual valuations, file Form 990-T if UBTI exceeds $1,000, and keep records showing every transaction was arm’s length and free of disqualified persons. A standard IRA custodian handles most of this work. With a checkbook IRA, you’re the custodian in practice, even if a passive custodian holds the account on paper. That passive custodian typically does not review your investments. The quality and legality of every decision rests with you.
No Safety Net When the IRS Looks
Checkbook IRAs have drawn increasing IRS attention. In McNulty v. Commissioner, a 2021 Tax Court case, the court found that an IRA owner who used IRA funds to buy a condominium and coins through an LLC had engaged in prohibited transactions. The case shows how quickly the structure collapses once the line between personal benefit and IRA investment blurs.
Standard IRA custodians at large brokerage firms limit investments to publicly traded securities, which makes prohibited transactions nearly impossible. A self-directed IRA custodian holds alternative assets and at least reviews transactions for obvious compliance failures. A checkbook IRA removes even that thin layer. The flexibility that makes the structure attractive is the same feature that makes it dangerous. If you’re considering one, the cost of a tax attorney who specializes in self-directed retirement plans is the only real safeguard the structure has.
