Can a Self-Directed IRA Own a Business? Rules, Taxes, and How It Works (2026)

TL;DR

Yes, a self-directed IRA can own a business, but only as a passive, arms-length investor, and self-directed IRA business ownership comes with four hard limits: you and your family (disqualified persons) cannot transact with or work for the business, the account must avoid prohibited transactions under IRC Section 4975, an active business held through a pass-through entity owes UBIT, and an IRA cannot own S corporation stock. If your goal is to fund and actively run your own business and draw a salary, a self-directed IRA is the wrong tool; that is what ROBS is for. This guide covers how it works, which entities qualify, the taxes, the rules you cannot break, and the alternatives. New to these accounts? Start with what a self-directed IRA is and how it works.

Can a Self-Directed IRA Own a Business? The Short Answer

Yes, but the answer splits into two very different paths, and confusing them is the most expensive mistake in this area.

• Passive investing (allowed): Your IRA can invest in a private business it does not control, run by people who are not you or your family. The IRA is a hands-off shareholder, and all profits flow back into the account.
• Funding your own active business (not allowed via an SDIRA): You cannot use your IRA to start, run, or draw a salary from a business you control. That triggers prohibited transactions and can disqualify the entire account. The legitimate route for that goal is ROBS (Rollover as Business Startup), covered below.

So the real question is not “can my IRA own a business,” it is “am I a passive investor or an active operator.” Get that straight first; everything else follows from it.

How Self-Directed IRA Business Ownership Actually Works

Self-directed IRA business ownership works through an arms-length investment held in the name of your IRA, usually as private stock, an LLC membership interest, or a limited partnership stake. The custodian holds the investment for the IRA, and you make the decision, but you cannot benefit personally before retirement.

Three mechanics define a compliant structure:

• The IRA is the owner, not you. The investment is titled to the IRA (for example, “Custodian FBO Your Name IRA”), and all income and gains return to the IRA tax-deferred or tax-free.
• You take no compensation. If a checkbook-control self-directed IRA LLC is used, you can serve as a non-compensated manager, but you cannot draw a salary, fees, or any personal benefit.
• No mixing of funds. You cannot co-invest personal money alongside the IRA in the same deal, and you cannot already own a stake in the business outside the IRA.

The IRA behaves like a silent, passive shareholder. The moment you treat it like your own checkbook, you have a problem.

What Businesses Can a Self-Directed IRA Invest In?

A self-directed IRA can invest in most private business structures, with two firm exceptions: S corporations and sole proprietorships. The entity type matters because it drives both eligibility and the tax bill.

An IRA cannot hold S corporation stock because S-corp shareholders must be individuals or certain trusts, and an IRA is neither, per the IRS. For an operating business, the C corporation is often the cleanest structure, for the tax reason explained next.

UBIT: The Tax Your IRA Owes on Active Business Income

Your IRA can owe tax even though it is tax-advantaged. When an IRA owns part of an active operating business through a pass-through entity (an LLC or limited partnership), its share of that business income is Unrelated Business Taxable Income (UBTI) and is subject to UBIT, filed on IRS Form 990-T.

The key facts:

• The trigger: active trade-or-business income that flows through to the IRA. Passive income (dividends, most interest, rent) is generally exempt, per the IRS.
• The rate: UBIT follows compressed trust tax rates, which reach 37% quickly, so it can take a large bite.
• The C corporation blocker: if the IRA holds C-corp stock instead of a pass-through interest, the corporation pays corporate tax and the dividends to the IRA are passive, so no UBIT applies. This is why operating businesses are often held as C corporations inside an IRA.
• Filing: a 990-T is generally required once UBTI exceeds $1,000, and your IRA may need its own EIN to file. See our self-directed IRA tax filing guide.

UBIT does not make business ownership a bad idea; it just means you must model the after-tax return, especially for active pass-throughs.

The Rules You Cannot Break: Disqualified Persons and the 50% Rule

The fastest way to lose the entire account is a prohibited transaction under IRC Section 4975, and business deals create more of these traps than any other asset. A prohibited transaction can disqualify the whole IRA, which is then treated as distributed, triggering income tax plus a 10% penalty if you are under 59.5.

The two concepts that catch people:

• Disqualified persons. You, your spouse, your parents and grandparents, your children and grandchildren, and their spouses are disqualified. Your IRA cannot buy from, sell to, lend to, or work for a business connected to them.
• The 50% rule. A business owned 50% or more (combined) by disqualified persons is itself a disqualified entity, so your IRA cannot invest in it. Minority, arms-length stakes in businesses run by unrelated people are where SDIRA business investing lives.

You also cannot personally guarantee the business’s debt, receive any compensation, or take any current personal benefit. For the full framework, see our self-directed IRA prohibited transactions guide and the IRS rules.

Self-Directed IRA Business Ownership vs ROBS vs Solo 401(k)

If a self-directed IRA cannot fund a business you run, what can? It depends on whether you want to be passive, active, or just borrow. Here is the honest comparison so you choose the right structure the first time.

ROBS is a real, IRS-recognized structure, not a loophole, but the agency scrutinizes it, so compliance must be exact (see the IRS ROBS compliance project). The simple rule: invest passively through a self-directed IRA, operate your own business through ROBS, and borrow small amounts through a Solo 401(k) loan.

Setting Up a Self-Directed IRA LLC (Checkbook Control)
Can a self-directed IRA own an LLC? Yes, and it is one of the most common ways people hold private investments in these accounts. The IRA buys 100% of a newly formed LLC, and the LLC holds the actual investments. This is called checkbook control, because you act as the manager and can write checks or move on a deal without asking the custodian to sign off each time.

The structure still lives under the same rules as the IRA itself. The self-directed IRA LLC rules that trip people up are the ones already covered above: no dealing with disqualified persons, no personal use, no salary to you. Checkbook control buys you speed, not a way around Section 4975.

Setting one up takes about four steps:

Open the IRA with a custodian and fund it by transfer or rollover.
Form the LLC as a single-member entity where the IRA is the only member and you are listed as manager.
Have the custodian send IRA cash to buy the membership interest, so the company is owned by the IRA, not by you.
Open a bank account in the LLC’s name and invest from there.
Some people handle this themselves. A do-it-yourself setup is possible if you are comfortable with the state filing and an operating agreement that keeps the account compliant, but one bad clause in that agreement can create a prohibited transaction, so many hand the formation to a custodian or facilitator.

One version of the question comes up backwards: can an LLC own an IRA? No. An IRA is a personal retirement account and can only belong to an individual. The company can be owned by the IRA, never the reverse.

Does a Self-Directed IRA LLC Need Its Own EIN?
Yes. Once the IRA owns an LLC, that LLC is its own legal entity and needs an EIN to open a bank account and, if it owes UBIT, to file Form 990-T. The self-directed IRA EIN belongs to the LLC or to the IRA trust, not to you personally, and you should never use your own Social Security number for it. It sounds like minor paperwork, but using the wrong number blurs the line between you and the account, which is the exact line these rules exist to protect.

Can a Self-Directed IRA Loan Money to a Business?
Yes. A self-directed IRA loan to a business is a debt investment instead of an equity one: the IRA lends money to a company and collects the interest, which flows back into the account. For a lot of investors this is cleaner than owning a piece of an operating business, because loan interest is passive income and usually sidesteps the UBIT that active pass-through ownership creates.

The same guardrails apply. The borrower cannot be you, your family, or any business you control, the note has to be a real arms-length loan on market terms, and you cannot personally guarantee it. Put the terms in writing, title the note to the IRA, and let the payments go back to the account.

Can a Roth IRA Own a Business, and Should It?
Everything above works with a Roth the same way it works with a Traditional account, so yes, a Roth IRA can own a business. The appeal for a Roth IRA business owner is what happens on the way out: qualified withdrawals are tax-free, so if the stake grows a lot, none of that gain is ever taxed. That makes a Roth worth a look for an investment you expect to appreciate.

Two caveats. UBIT does not care which type of IRA you use, so active pass-through income owes the tax in a Roth just like a Traditional account. And “own” still means passive and arms-length. A Roth does not let you run the company or pay yourself, so the same wall between you and the business stays up.

Can a Self-Directed IRA Invest in a Small Business or Startup?
Yes. A self-directed IRA can invest in a small business or a startup as long as the stake stays passive and arms-length. You put IRA money into a private company run by people unrelated to you, and the returns go back to the account. What you cannot do is buy into a business you or your family already control, or one where you plan to work or draw a paycheck.

Two things decide whether it works. The 50% rule bars the IRA from any company that disqualified persons own half or more of, and the entity type sets the tax bill. If the business is an active pass-through, expect UBIT on your share. A stake in that same company set up as a C corporation avoids it.

Key Takeaways

• A self-directed IRA can own a business only as a passive, arms-length investor. To run your own business and draw a salary, use ROBS instead.
• Self-directed IRA business ownership requires the IRA to be the titled owner, you to take no compensation, and no mixing of personal funds.
• An IRA can invest in C corporations, multi-member LLCs, and limited partnerships, but not S corporations or sole proprietorships.
• Active business income from a pass-through is UBTI and owes UBIT on Form 990-T; holding C-corp stock blocks UBIT because the corporation pays its own tax.
• Disqualified persons (you and close family) cannot transact with or work for the business, and the 50% rule bars investing in entities they largely own.
• A prohibited transaction under IRC Section 4975 can disqualify the whole account, so arms-length minority stakes in unrelated businesses are the safe zone.
