A single prohibited transaction inside a self-directed IRA can trigger an ordinary income bill on the entire account balance — $500,000 taxable in one year if you violated the rules with a $500,000 IRA. That's the downside. The upside is that a self-directed IRA (SDIRA) can hold foreign real estate, physical gold, private notes, and startup equity — investments that standard custodians won't touch. For US expats building portable wealth across borders, that flexibility is real. Three traps are especially costly for expats: the UBIT leverage charge, the PFIC problem inside the IRA, and the prohibited transaction rule itself. This guide explains all three, along with custodian fees and how contribution limits interact with the Foreign Earned Income Exclusion.

For context on how standard IRAs and 401(k) plans behave while you're abroad, see the expat retirement account guide. For the full framework on avoiding Passive Foreign Investment Companies, see the PFIC guide for US expats.

What Makes an IRA Self-Directed

All IRAs — traditional, Roth, SEP, and SIMPLE — allow you to invest in alternative assets in theory. In practice, custodians like Fidelity, Vanguard, and Charles Schwab limit you to stocks, bonds, ETFs, and mutual funds. A self-directed IRA (SDIRA) is an IRA held at a specialized custodian that does not restrict you to those assets and instead holds and administers whatever you direct it to hold.

The custodian's role in an SDIRA is administrative, not advisory. They process transactions, hold assets in the name of the IRA, prepare the annual fair market value statement (Form 5498), and keep your account legally compliant. They do not tell you whether an investment is a good idea. The IRS allows this structure, and the same annual contribution limits, deduction rules, and required minimum distribution rules apply as with any other IRA.

Standard IRA vs. SDIRA: The Key Difference

The main difference is not the tax treatment — that is identical. The difference is the asset universe and the compliance burden. SDIRAs require investors to understand the prohibited transaction rules and UBIT rules themselves because the custodian won't catch violations. Mistakes inside an SDIRA can be expensive in ways that never arise with a standard brokerage IRA.

What an SDIRA Can and Cannot Hold

The IRS prohibits three specific asset classes in any IRA: life insurance policies, collectibles (art, antiques, rugs, most coins), and S-corporation stock. Everything else is technically allowed, including assets that standard brokerages refuse to custody.

Asset Class	Allowed in SDIRA?	Expat Considerations
US real estate (cash purchase)	Yes	No UBIT if purchased with cash. Prohibited transaction risk if you personally use the property.
Foreign real estate (cash purchase)	Yes	Allowed, but foreign taxes paid on IRA property cannot be taken as a personal foreign tax credit. Foreign currency gains also exist.
Physical gold and silver	Yes (IRS-approved coins and bars only)	Must be held by an IRS-approved depository — cannot be stored at home or abroad in a personal safe.
Cryptocurrency	Yes (via compliant custodian or LLC)	Taxed as property inside the IRA; gains sheltered from current taxation. Roth SDIRA is ideal for high-growth crypto positions.
Private loans (promissory notes)	Yes	Cannot lend to disqualified persons (yourself, spouse, parents, children). Interest income grows tax-deferred.
Private company equity	Yes, if C-corp or LLC (not S-corp)	Active business income may trigger UBIT. Foreign corporations can create PFIC issues.
US-domiciled ETFs/mutual funds	Yes — no PFIC issue	Vanguard VTI, iShares IVV, and similar US-registered funds are NOT PFICs even if they invest globally.
Foreign-domiciled ETFs/mutual funds	Technically yes — but PFIC rules apply	A UCITS ETF registered in Ireland is a PFIC inside your IRA. The tax deferral advantage may be partially offset by PFIC reporting obligations.
Life insurance, collectibles, S-corp stock	No	Prohibited by IRC Section 408(m) and related rules.

UBIT and UDFI: The Leverage Trap

The IRA tax shelter protects passive income — dividends, interest, rents from unleveraged property, and capital gains. When an IRA earns income from an active business or from leveraged investments, the shelter breaks down under two related rules.

Unrelated Business Income Tax (UBIT)

If your SDIRA holds an investment that generates "unrelated business taxable income" (UBTI), the IRA owes tax on that income at trust tax rates — currently up to 37%. UBTI typically arises when:

• The IRA owns a working business (a restaurant, a retail operation, an active rental managed by an LLC that is treated as a partnership)
• The IRA is a limited partner in a private equity or real estate fund that generates UBTI
• The IRA holds debt-financed property (the UDFI rule below)

Passive income — unleveraged rental income, dividends, interest from notes, capital gains on real estate — is generally exempt from UBIT. Confirm with a tax advisor before investing IRA funds in any structure that involves an operating business or a partnership with active operations.

Unrelated Debt-Financed Income (UDFI) and the Mortgage Problem

UDFI is the portion of income attributable to debt financing inside the IRA. If your SDIRA buys a $300,000 property using $150,000 of IRA cash and a $150,000 non-recourse loan, 50% of the rental income and 50% of the eventual sale gain is UDFI — taxable at trust rates. The UDFI fraction is calculated as the average acquisition indebtedness divided by the average adjusted basis of the property.

Per IRS guidance on unrelated business income tax, the IRA (or its checkbook LLC) files Form 990-T if UBTI exceeds $1,000 in a year. The tax is paid from IRA assets — reducing the tax-sheltered pool. Many expat investors find that all-cash SDIRA purchases avoid UBIT entirely and are simpler to manage.

Prohibited Transactions: The Landmine That Voids Your IRA

A single prohibited transaction ends the IRA's tax-exempt status as of January 1 of the year the violation occurred. The entire IRA balance is treated as a taxable distribution on that date. For a $500,000 IRA, that means a $500,000 ordinary income hit — in one year, regardless of your age or the size of the transaction that triggered it.

Per IRS rules on prohibited transactions, the six categories of prohibited transaction all involve dealings between the IRA and a "disqualified person" — broadly defined as you, your spouse, your lineal descendants, and entities you or they control. Specifically, you cannot:

1. Sell or lease property to the IRA that you currently own
2. Use IRA-owned property yourself — including staying overnight in an IRA-owned rental, even for "inspection"
3. Hire yourself or a disqualified family member to manage IRA-owned real estate
4. Personally guarantee a loan the IRA takes (non-recourse financing only)
5. Pay yourself a management fee from the IRA
6. Lend IRA funds to yourself or a disqualified person

Foreign Investments Inside Your SDIRA: The Expat Angle

SDIRAs can hold foreign assets, including real estate located outside the US and foreign company stock. But two complications are specific to international investments.

The PFIC Problem for Foreign-Registered Funds

If your SDIRA holds a foreign-domiciled ETF or mutual fund — a UCITS ETF based in Ireland, a locally-listed fund in the country where you live — that fund is almost certainly a Passive Foreign Investment Company (PFIC). The IRS PFIC rules don't disappear inside an IRA; they still apply.

Holding a PFIC inside an IRA doesn't trigger the punitive excess-distribution tax during accumulation (because the IRA doesn't pay tax currently anyway). But when you distribute from the IRA and include the income on your personal return, the IRS may expect Form 8621 reporting for PFICs held in the account during the period. The practical interaction is complex enough that most SDIRA specialists recommend sticking to US-domiciled funds — even funds that invest internationally, like VEA or VXUS — inside an IRA, and buying foreign-registered funds in taxable accounts where the QEF or mark-to-market election can be cleanly applied.

See the full PFIC treatment analysis in the PFIC guide for US expats before buying any foreign-registered fund inside any US retirement account.

Foreign Real Estate in an SDIRA

SDIRAs can legally hold foreign real estate, and many custodians do handle it. The IRA title typically holds the property through a single-member LLC (a "checkbook IRA" structure) to manage the operational complexity of a foreign transaction.

Key complications for expat investors:

• Foreign taxes: Rental income from IRA-owned foreign property is still subject to local taxes in the country where the property is located. Those foreign taxes cannot be claimed as a personal foreign tax credit on your US return because the income belongs to the IRA, not to you.
• Foreign currency: If the property is denominated in a non-dollar currency, gains and losses are subject to Section 988 currency rules when the property is sold and proceeds converted to USD. This can create taxable events inside the IRA.
• Local legal requirements: Many countries restrict foreign ownership of real estate, or require specific legal structures. The IRA LLC must comply with local property law, which adds both legal cost and complexity.
• No personal benefit: You cannot live in, use, or rent the property to family members at below-market rates. The property must function as a pure investment at arm's length at all times.

Can You Contribute If You're Using the FEIE?

Yes — but only if you have US-taxable earned income remaining after the FEIE exclusion. The 2026 FEIE amount is approximately $132,900. If your total foreign earned income is $132,900 or less and you exclude all of it, your compensation base for IRA contributions is zero, and you cannot make an IRA contribution that year.

If your earned income exceeds $132,900, the excess above the FEIE can support an IRA contribution. The 2026 contribution limit is $7,500 ($8,600 if age 50 or older under SECURE 2.0's increased catch-up provision). You can contribute up to the lesser of your taxable earned income or the $7,500 limit.

SEP-IRA and SOLO 401(k) contributions also reduce to the extent earned income is excluded by the FEIE. Self-employed expats using the full FEIE often find that a taxable investment account or a Roth conversion ladder (converting pre-existing IRA funds rather than making new contributions) is more practical in zero-income years. For more on Roth strategy before and during expatriation, see the Roth IRA guide for US expats.

Choosing an SDIRA Custodian

Major brokerage firms don't offer SDIRA custody for alternative assets. You'll need a specialized custodian. Several are available with meaningfully different fee structures.

Custodian	Annual Fee (approx.)	Best For
IRA Financial	$495/year flat (all accounts)	Checkbook IRA LLC structure; flat fee makes it cost-effective for high-value accounts
Equity Trust	Tiered — scales with account value	One of the oldest and largest SDIRA custodians; broad asset support
Entrust Group	From $199/year for small accounts	Lower-cost entry point for smaller SDIRA balances
Alto IRA	Low flat fee; crypto-focused plans available	Crypto, startup, and alternative investment access through curated platforms
Directed IRA	Annual fee varies by asset type	Strong support for checkbook LLC and real estate-focused investors

All SDIRA custodians are passive — they do not validate whether your investment is legal, fair-valued, or a good decision. The due diligence is entirely yours. See how Charles Schwab and Interactive Brokers compare for standard expat brokerage access (outside the SDIRA context) in the expat brokerage guide.

Data note: Annual fees sourced from publicly posted custodian fee schedules as of mid-2026 and subject to change. IRA contribution limit of $7,500 and catch-up limit of $8,600 reflect 2026 figures. FEIE exclusion of approximately $132,900 for 2026. Verify all current figures at IRS.gov before contributing. As of July 2026.

SDIRAs Are Powerful — and Unforgiving

A self-directed IRA is one of the few tools that lets a US expat shelter gains from foreign real estate, gold, and private investments inside a tax-deferred or tax-free wrapper. The case for using one is real. So is the case for being careful: the prohibited transaction rule, the UBIT trap on leveraged real estate, and the PFIC complexity for foreign-registered funds are all genuine costs that don't apply to standard IRAs.

The expat investors who benefit most from SDIRAs are those who: (1) buy US or foreign real estate all-cash (no UDFI), (2) hold US-domiciled funds rather than foreign ETFs inside the account, and (3) maintain strict separation between personal use and IRA-owned assets. A US-qualified tax professional experienced with both SDIRA rules and expat taxation is worth consulting before your first transaction.
