US Tax Considerations for Americans Buying Property in Mexico

Buying a home in Mexico doesn't, by itself, create a new US tax obligation. But once that property starts generating rental income, or once you look closely at how it's actually held, a few genuinely important reporting rules come into play — and getting them wrong is more about paperwork than money owed.

Owning the Property: No Special Filing Just for That

Simply owning Mexican real estate in your own name does not require you to file anything extra with the IRS. Direct ownership of foreign real estate is not, by itself, a "specified foreign financial asset" for Form 8938 purposes, and it doesn't trigger FBAR (Report of Foreign Bank and Financial Accounts) reporting either. A personal vacation home you never rent out generally sits outside these reporting regimes entirely.

The Fideicomiso Question, Settled

For years, US buyers and even some advisors worried that a fideicomiso — the bank trust structure required to buy in Mexico's restricted zone — might count as a "foreign trust," triggering the notoriously punishing Form 3520 and 3520-A filings (and their steep penalties for getting it wrong). The IRS settled this in Revenue Ruling 2013-14: a standard Mexican land trust used to hold a personal residence is not considered a trust for US tax purposes at all. No trust, no Form 3520, no Form 3520-A. This is one of the most useful pieces of clarity available to American buyers, and it's worth confirming your specific trust deed fits the standard pattern with a cross-border tax preparer — but for the overwhelming majority of residential fideicomisos, this exemption applies cleanly.

Once You Rent It Out

This is where real reporting obligations begin. The IRS taxes US citizens and green card holders on worldwide income, so rental income from your Mexican property must be reported on Schedule E of your US return, just like a domestic rental. The good news is that the same deductions apply: mortgage interest, property management fees, maintenance, depreciation, and — importantly — Mexican taxes paid on that same income can generally be claimed as a foreign tax credit, reducing double taxation.

FBAR and Form 8938: When They Actually Apply

• FBAR is triggered by foreign financial accounts — a Mexican bank account you open to handle predial, HOA payments, or rental proceeds — once the aggregate balance across all foreign accounts exceeds $10,000 at any point in the year. The real estate itself doesn't trigger it; the bank account might.
• Form 8938 has its own, generally higher thresholds and applies to specified foreign financial assets. Directly held real estate is excluded, but if the property is held through a foreign corporation, partnership, or (non-exempt) trust structure, the entity becomes reportable — and by extension so is the property inside it.

Selling the Property

When you sell, any gain is reportable on your US return, with a foreign tax credit available for Mexican capital gains tax paid on the same sale (Mexico's rules on this are covered in a separate article, including the exemptions available for a primary residence).

State Taxes

Depending on which US state you're domiciled in, state tax treatment of foreign rental income and capital gains can differ from federal treatment — this matters most for owners relocating from high-tax states, which we cover in its own article.

FAQ

Q: Do I need to report the fideicomiso itself on my tax return?

A: Under Revenue Ruling 2013-14, a standard residential fideicomiso is not treated as a foreign trust, so it generally does not require Form 3520/3520-A reporting. This doesn't mean zero reporting ever applies to your situation — confirm with a preparer familiar with Mexican property specifically.

Q: What if I only rent occasionally, like a few weeks a year?

A: Any rental income is reportable, regardless of how occasional it is. The reporting obligation isn't tied to a minimum number of rental days.

Q: Does buying property in Mexico affect my US tax residency?

A: No — US citizens and green card holders remain taxable on worldwide income regardless of where they own property, unless they take the separate, significant step of formally expatriating.

Q: Should I use a US accountant or a Mexican one?

A: Ideally both, coordinating with each other — a Mexican accountant (contador) for local filings and a US preparer experienced in cross-border property for the US side. Few generalist preparers on either side handle this combination well by default.
