Fideicomiso Guide for U.S. Citizens

U.S. citizens are by far the largest group of foreign property buyers in Mexico. This page covers what's specific to American buyers — IRS reporting (FBAR / Form 8938), how the fideicomiso interacts with U.S. estate planning, currency strategy, and what to expect from the cross-border process.

Estimates only. Every fee, tax, cost and total on this page is an estimate for general information, based on the 2026 published government tables and typical quotes from banks, notaries and appraisers. What you actually pay is set by each office, bank, notary or provider when you pay it, and changes with the exchange rate, the appraisal and the details of your property. Mexico Trust Services confirms figures only in a written quote.

The basics

As a U.S. citizen, you can buy property anywhere in Mexico with the same legal rights as any other foreign national. Inside the restricted zone (most coastal and border areas), you use a fideicomiso — a 50-year renewable bank trust where a Mexican fiduciary bank holds legal title and you are the named beneficiary. The setup, cost, and timeline are identical for U.S. and Canadian buyers.

IRS reporting for U.S. owners

FBAR (FinCEN Form 114): The fideicomiso is generally NOT a foreign financial account requiring FBAR reporting (the IRS guidance treats it as foreign real-estate ownership, not a foreign account). However, if you have a Mexican BANK ACCOUNT with more than $10,000 USD aggregate balance at any point in the year, FBAR is required separately.
Form 8938 (FATCA): The IRS has historically NOT treated the fideicomiso itself as a foreign trust requiring Form 8938 reporting (Rev. Rul. 2013-14 and earlier guidance), but practice has varied. Confirm with a U.S. tax professional familiar with Mexican fideicomisos.
Form 3520/3520-A (foreign trust reporting): The IRS specifically issued Revenue Ruling 2013-14 stating that Mexican fideicomisos for residential real-estate ownership are NOT trusts for U.S. tax purposes, so Forms 3520/3520-A are NOT required. This was a major clarification — earlier ambiguity caused significant overreporting.
Annual income tax: If you rent the property, U.S. tax on the rental income is required (you can usually credit foreign tax paid in Mexico). If it's a personal residence or vacation home, no annual U.S. tax is owed beyond your usual filings.
Capital gains on sale: When you sell, U.S. capital gains tax applies (with foreign tax credit for Mexican capital gains tax paid). The U.S. cost basis includes purchase price + all closing costs (including fideicomiso setup).

U.S. estate planning interaction

A fideicomiso names successor beneficiaries directly in the trust contract. When you die, your Mexican property passes to those named heirs without going through Mexican probate. However, the U.S. side still applies — your worldwide estate (including the fideicomiso interest) is included in your U.S. estate-tax calculation if your total estate exceeds the federal exemption (currently ~$13.6M per person, so most owners are unaffected). For U.S. owners, a living trust or a U.S. will does not by itself transfer the fideicomiso rights: name substitute beneficiaries in the trust, and consider a Mexican will for property in Mexico.

Currency strategy for U.S. buyers

Most fideicomiso fees split into USD-denominated charges (the Mexico Trust Services fee, paid to Galarza Legal in Mexico) and MXN-denominated charges (notary, SRE permit, bank, predial, transfer tax — all paid to Mexican parties). For the MXN charges, Wise (formerly TransferWise) typically saves 1–3% versus a US bank wire. See our Wise payment guide for the step-by-step. Closing-day cash needs are typically pre-funded by wire or Wise to the closing notary.

Border-zone considerations for U.S. buyers

If your property is in northern Baja (Tijuana, Rosarito, Ensenada) or San Felipe, you can drive a U.S.-plated car without a temporary import permit (the entire Baja California peninsula is in the vehicle "free zone"). For property elsewhere — Cabo, Mayan Riviera, mainland Mexico — you'll need a TIP if driving a U.S. car. Mexican car insurance is required regardless and costs $150–$400 USD/year.

Frequently Asked Questions

Will buying a fideicomiso affect my U.S. tax filing complexity?

Slightly. You'll add foreign-property reporting to your annual Schedule E if you rent it out, and you may need to report a Mexican bank account on FBAR if you maintain one. But the fideicomiso itself does NOT trigger Form 3520 (foreign trust) reporting per IRS Rev. Rul. 2013-14 — that was a key clarification several years ago.

Can I use my U.S. retirement funds (IRA, 401k) to buy Mexican property?

Only through a self-directed IRA structure, which has strict rules and tax implications. Most U.S. tax professionals recommend cash purchase from after-tax savings rather than retirement funds — talk to a U.S. CPA before structuring this way.

Does my U.S. mortgage carry over to Mexico?

No. U.S. mortgages do not work for Mexican property purchases. Some Mexican banks (BBVA, BIM) offer dollar-denominated mortgages to U.S. buyers, but rates are typically 8–12% and approval is conservative. Most U.S. buyers pay cash. These figures are estimates; the final amounts are set by each office, bank, notary or provider when you pay them.

What about my Medicare and Social Security if I move to Mexico full-time?

Social Security is paid worldwide. Medicare does NOT cover medical care in Mexico — most U.S. retirees in Mexico carry Mexican private insurance (IMSS or private) for medical needs. We can refer you to bilingual insurance brokers in Baja.
