FBAR & FATCA: US Tax Reporting Rules Every Cabo Property Owner Must Know

Your Cabo property is not reported on FBAR or FATCA. But the Mexican bank account you opened to pay HOA fees, utilities, and property taxes? That triggers both filings the moment your aggregate foreign accounts hit $10,000. Miss the filing and the IRS penalty starts at $10,000 per year — per form. Here is exactly what you owe and when.

The Big Relief: Your Property Is NOT Reported

Let me start with the good news because I have watched too many Cabo buyers panic over this: real estate held directly in your name (or through a fideicomiso bank trust) is not a reportable asset on either FBAR or FATCA Form 8938. The IRS does not consider foreign real estate a "financial account" or a "specified foreign financial asset" for purposes of these filings.

That $1.5 million condo in Pedregal? Not on your FBAR. That $3 million villa in Palmilla? Not on your Form 8938. The property itself is invisible to both filings.

But — and this is the "but" that gets people in trouble — the moment you open a Mexican bank account to manage that property, the reporting clock starts ticking. And almost every Cabo property owner opens a Mexican bank account.

FBAR: The $10,000 Tripwire

FBAR stands for Foreign Bank Account Report, officially FinCEN Form 114. It is filed with the Financial Crimes Enforcement Network (FinCEN), not the IRS — though the IRS enforces the penalties.

The rule is simple: if you are a US person (citizen, green card holder, or resident alien) and the aggregate value of all your foreign financial accounts exceeds $10,000 at any point during the calendar year, you must file an FBAR.

Key details that trip up Cabo property owners:

• Aggregate means combined. If you have a Banorte checking account with $6,000 and a BBVA savings account with $5,000, your aggregate is $11,000. You file. It does not matter that neither account individually exceeds $10,000.
• "At any point" means peak balance. Even if your account held $10,001 for a single day — say, when you received a rental payment before transferring it to the US — you are over the threshold for the entire year.
• Signature authority counts. If you have signature authority over a property management company's Mexican bank account (even if it is not your money), that account is reportable on your FBAR.
• Fideicomiso bank accounts. If your fideicomiso trust holds financial assets beyond the real estate itself (rare, but it happens), those assets may be reportable. The real estate is not, but cash or investments held inside the trust structure could be.

FATCA Form 8938: The Higher Threshold

FATCA (the Foreign Account Tax Compliance Act) requires reporting on Form 8938, which is filed with your annual tax return — not separately like the FBAR.

The thresholds are higher and depend on your filing status and where you live:

• Single, living in the US: File if total foreign financial assets exceed $50,000 on the last day of the year, or $75,000 at any point during the year
• Married filing jointly, living in the US: $100,000 on the last day, or $150,000 at any point
• Single, living abroad: $200,000 on the last day, or $300,000 at any point
• Married filing jointly, living abroad: $400,000 on the last day, or $600,000 at any point

Most Cabo vacation-home owners living in the US will not hit the $50,000 FATCA threshold with a single property management bank account. But full-time expats with Mexican investment accounts, or owners who collect substantial rental income through Mexican accounts, can cross the line quickly.

Remember: FBAR and FATCA are separate filings with separate thresholds. You can owe one without owing the other, or you can owe both. They overlap but are not identical.

Mexican Bank Accounts That Trigger Reporting for Cabo Owners

Here are the specific accounts that most commonly push Cabo property owners over the FBAR threshold:

1. HOA and utility payment accounts. Many developments require or recommend a Mexican bank account for automatic debit of HOA fees, CFE (electricity), OOMSAPAS (water), and internet. Even if balances are small, they count toward the aggregate.
2. Rental income accounts. If you rent your property and receive pesos into a Mexican account — whether you manage it yourself or through a property manager — that account is reportable. See our vacation rental income guide for the revenue side of this equation.
3. Property management company accounts. If your property manager holds funds in a pooled Mexican bank account and you have signature authority, it hits your FBAR. Clarify the account structure with your manager before signing.
4. Joint accounts with a Mexican spouse or partner. Common in expat households. Both parties' names on the account means it appears on both parties' FBARs.
5. Mexican investment or brokerage accounts. Less common for vacation-home owners but typical for full-time expats who invest locally. GBM, Kuspit, or BBVA investment accounts are all reportable.

The Penalty Structure: Why This Matters

The penalties for non-compliance are where this gets serious:

FBAR penalties:

• Non-willful violation: up to $16,536 per account per year (2026 inflation-adjusted)
• Willful violation: up to the greater of $100,000 or 50% of the account balance
• Criminal penalties for willful violations: up to $250,000 fine and 5 years imprisonment

FATCA Form 8938 penalties:

• Failure to file: $10,000 per year
• Continued failure after IRS notice: additional $10,000 for each 30-day period, up to $50,000 maximum
• Frozen statute of limitations: the IRS can audit your entire return for any year with an unfiled 8938 — there is no time limit until you file

The frozen statute of limitations is the sleeper penalty. Normally the IRS has three years to audit your return. Miss a Form 8938 and that three-year clock never starts. Your return stays open for audit indefinitely. I have seen this bite Cabo owners who did not realize they had a filing obligation until five years after purchase — and then faced potential audit exposure on every return going back to the year they opened the account.

Fideicomiso Trust Reporting: The Gray Area

The fideicomiso (bank trust) used to hold coastal property in Mexico creates a reporting question that has no definitive IRS ruling. Here is the issue: the IRS has not clearly stated whether a Mexican fideicomiso constitutes a "foreign trust" for purposes of Form 3520 and Form 3520-A reporting.

Some tax practitioners take the position that the fideicomiso is a trust and must be reported annually. Others argue that because the beneficiary (you) retains all economic rights and the bank is simply a title holder, it is not a trust in the US tax sense. Both positions have merit and neither has been definitively settled by the IRS or the courts.

My advice: talk to your cross-border CPA before closing and agree on a reporting position. If they recommend filing Form 3520/3520-A, the cost is typically $500-$1,500 per year in additional preparation fees. If they recommend not filing, document the reasoning in writing so you have a "reasonable cause" defense if the IRS ever challenges the position. What you do not want is to discover this question three years after closing and have no documentation of your analysis.

Rental Income: The Double-Reporting Obligation

If you rent your Cabo property — even occasionally — you have tax obligations in both countries. This is separate from FBAR and FATCA, but it catches the same pool of Cabo property owners:

• Mexico: Rental income from Mexican property is subject to Mexican income tax (ISR). You must register with SAT (Mexico's IRS equivalent) and file monthly or quarterly returns. The tax rate is typically 25% on gross rental income for non-residents, or you can elect to deduct expenses and pay on net income.
• United States: As a US citizen or resident, you report worldwide income including Mexican rental income on your US tax return. You can claim a foreign tax credit for Mexican taxes paid, which typically offsets most or all of the US tax liability on the same income.
• Rental bank accounts: The Mexican bank account receiving rental income counts toward your FBAR aggregate. If rental deposits push your aggregate foreign accounts above $10,000 at any point during the year, you file.

The interaction between Mexican ISR, US income tax, foreign tax credits, FBAR, and potentially FATCA is exactly why a cross-border CPA is not optional — it is a requirement. Budget for it from day one of ownership.

The US-Mexico Tax Treaty: What It Does and Does Not Do

The US-Mexico tax treaty is useful but widely misunderstood. Here is the reality:

What the treaty DOES:

• Prevents double taxation on rental income, capital gains, and other income sourced in Mexico
• Allows you to claim foreign tax credits on your US return for Mexican taxes paid (predial, ISR on rental income, capital gains tax)
• Establishes residency tie-breaker rules if you could be considered a tax resident of both countries

What the treaty does NOT do:

• Eliminate FBAR reporting obligations
• Eliminate FATCA Form 8938 reporting obligations
• Exempt you from US worldwide income reporting
• Override FinCEN filing requirements

The treaty is about taxation — how much you pay and to whom. FBAR and FATCA are about reporting — telling the US government your accounts exist. These are separate legal frameworks and the treaty does not bridge them.

Filing Deadlines and How to File

Here are the deadlines you need in your calendar:

• FBAR (FinCEN 114): Due April 15 with automatic extension to October 15. Filed electronically through the BSA E-Filing system. This is a separate filing from your tax return — do not assume your CPA handles it automatically.
• FATCA (Form 8938): Filed with your annual tax return. Due April 15 (or October 15 with an extension). This one is part of your return, so your CPA should handle it — but you need to give them the account information.
• Form 3520/3520-A: If your fideicomiso is classified as a foreign trust (the IRS position is evolving), you may owe annual trust reporting. Due with your return. This is a gray area — get professional advice.

Practical Steps for Cabo Property Owners

Here is the action plan I give every buyer who closes on a Cabo property:

1. Document every Mexican bank account. Bank name, account number, account type, and maximum balance during the year. Do this from day one — reconstructing balances years later is painful.
2. Track peak balances monthly. The FBAR threshold is based on the highest aggregate value at any point during the year. A one-day spike above $10,000 triggers the filing for the entire year.
3. Hire a cross-border CPA before your first tax season as an owner. Not a regular CPA — one who does Mexico-US compliance regularly. Budget $500-$2,000 annually above your normal tax prep costs.
4. File proactively. If you discover you missed prior-year FBARs, use the IRS Streamlined Filing Compliance Procedures to come into compliance with reduced penalties. The program exists specifically for taxpayers who were non-willfully non-compliant. Do not wait for the IRS to find you.
5. Keep your Mexican bank account structure simple. One account for property expenses, one for rental income if applicable. The fewer accounts, the simpler the reporting.
