Buying Cabo Property Through a US Trust or Family LLC: What Actually Works

A US revocable trust or family LLC can be named as the beneficiary of a Mexican fideicomiso — and when done correctly, it is one of the smartest estate planning moves you can make for your Cabo property. I have walked three clients through this exact structure in the last year, and I will tell you right now: the setup is not complicated, but the reporting requirements are real, and the bank selection matters more than most buyers realize.

This is not the same as forming a Mexican SA de CV to hold property. That is a completely different ownership vehicle with different tax implications, different annual costs, and different use cases. What we are talking about here is keeping your existing US estate plan intact while owning Mexican real estate — so your heirs do not have to navigate ancillary probate in a foreign country.

How the Structure Actually Works

In a standard fideicomiso, a Mexican bank holds title to the property as trustee, and you — the individual foreign buyer — are named as the beneficiary. You control the property, receive the income, and can sell it at any time. The bank is just the legal titleholder required by Mexico's Ministry of Foreign Affairs (SRE) for properties in the restricted zone (within 50 km of the coast).

When you name a US trust or LLC as the beneficiary instead of yourself individually, the mechanics are identical. The Mexican bank still holds title. The fideicomiso still works the same way. The only difference is that the beneficiary line reads "The Smith Family Revocable Trust" or "Smith Holdings LLC" instead of "John Smith."

Why does this matter? Because when John Smith dies, his individual fideicomiso beneficiary interest must go through a Mexican probate proceeding — a separate legal process from whatever happens with his US estate. That process takes 6 to 18 months, costs $5,000 to $15,000 in legal fees, and requires his heirs to navigate the Mexican court system. With a trust as beneficiary, the trust continues to exist after John dies. The successor trustee steps in, and the property transfers according to the trust document — no Mexican probate required.

Revocable Trust vs. LLC: Which Structure

I have seen both work. The choice depends on your existing estate plan and your tax situation.

Revocable Living Trust: This is the most common structure I see with Querencia and Palmilla buyers. If you already have a revocable trust as part of your US estate plan, naming it as the fideicomiso beneficiary is straightforward. The trust is a disregarded entity for US tax purposes — meaning the IRS treats you and the trust as the same taxpayer. Rental income flows through to your personal return. Capital gains on sale are taxed at your individual rates. There is no separate entity-level tax return.

Family LLC: If you co-own property with partners, siblings, or children, an LLC offers more flexibility for ownership percentages and management roles. However, a multi-member LLC is not a disregarded entity — it files its own partnership return (Form 1065), and each member gets a K-1. Single-member LLCs are disregarded like trusts, which simplifies things.

The critical difference: some Mexican banks are more comfortable with trusts than with LLCs. In my experience, this is because Mexican banking compliance officers understand trust structures — Mexico has its own robust trust law — but are less familiar with the LLC concept, which does not have a direct Mexican equivalent.

Which Mexican Banks Accept Entity Beneficiaries

This is where the rubber meets the road. Not every fideicomiso trustee bank will accept a US entity as beneficiary. Here is what I have seen in practice:

• Monex: Generally the most receptive to US trust and LLC beneficiaries. Their compliance team has processed enough of these that the documentation requirements are well-established. Expect to provide the full trust instrument or LLC operating agreement, articles of organization, EIN letter, and a certificate of good standing
• Banorte: Accepts trust beneficiaries and most LLC structures. Processing time is slightly longer than Monex — budget an extra 2 to 3 weeks for the additional compliance review
• BBVA Mexico: Will accept revocable trusts in most cases. LLCs are case-by-case and depend on the local branch's compliance comfort level
• Scotiabank: The largest fideicomiso trustee bank in Mexico, but some branches still refuse entity beneficiaries entirely. The Cabo San Lucas branch has historically been more receptive than the San Jose del Cabo branch, but this changes with personnel. Always confirm before committing
• HSBC Mexico: Accepts both structures in theory, but the documentation requirements are the most extensive. Budget extra time and patience

My recommendation: start with Monex or Banorte. If your notario suggests a different bank, ask specifically whether that bank has processed US entity beneficiaries in the last 12 months. A bank that has never done it will make your closing miserable.

IRS Reporting Requirements: Forms 3520 and 3520-A

This is the part most buyers skip past and later regret. When a US person is a beneficiary of a foreign trust — which is exactly what a fideicomiso is under IRS classification — certain reporting obligations kick in.

Form 3520 (Annual Return to Report Transactions With Foreign Trusts): Required if you receive distributions from the fideicomiso (which includes rental income) or make transfers to the trust (your purchase payment). Due with your tax return, including extensions. Penalty for late filing: the greater of $10,000 or 35% of the gross reportable amount.

Form 3520-A (Annual Information Return of Foreign Trust With a US Owner): Required if you are treated as the owner of the foreign trust for US tax purposes. Due March 15 (for calendar year trusts), with a 6-month extension available. Same penalty structure as 3520.

Now here is the good news: the IRS has historically taken the position that a fideicomiso used solely for property ownership (not as an investment vehicle) may not require 3520-A filing. But the guidance is not crystal clear, and the penalties are severe enough that most cross-border tax advisors recommend filing to be safe. The cost to prepare these forms is $500 to $1,500 per year through a qualified CPA.

You also need to continue filing FBAR (FinCEN 114) if you have signature authority over a Mexican bank account with a balance exceeding $10,000 at any point during the year. And if your trust or LLC is the account holder, the entity's EIN triggers the filing — not just your SSN.

The Estate Planning Advantages

The biggest reason buyers use this structure is estate planning. Here is the math:

Without a trust as beneficiary: When you die, your heirs must open a sucesión (probate proceeding) in Mexico. This requires hiring a Mexican attorney, petitioning a Mexican court, obtaining an apostilled death certificate, potentially getting a Mexican will probated (or worse, navigating intestacy rules if you have no Mexican will), and waiting 6 to 18 months. Cost: $5,000 to $15,000. During this time, the property sits in limbo — it cannot be sold, refinanced, or transferred.

With a trust as beneficiary: When you die, the successor trustee named in your trust document steps into your role as the beneficiary of the fideicomiso. The Mexican bank updates its records. No Mexican court proceeding. No separate Mexican probate. Total cost: the bank's administrative fee for the beneficiary change, typically $500 to $1,000. Timeline: 30 to 60 days for the bank paperwork.

That is a $10,000+ savings and a year of headaches avoided. For properties in Pedregal, Chileno Bay, and other high-value communities, where the estate tax implications alone can run into six figures, the structure is even more compelling.

Common Pitfalls I Have Seen

In my experience advising buyers across Diamante, Querencia, and the broader Los Cabos market, these are the mistakes that come up repeatedly:

• Not verifying bank acceptance before signing the purchase agreement: The worst scenario is discovering your chosen bank will not accept an LLC beneficiary after you have already committed to the purchase. Verify first, then sign
• Using an LLC that is not in good standing: If your LLC's annual report is delinquent in its home state, the Mexican bank will not accept it. Get your entity current before you start the purchase process
• Forgetting that LLC operating agreements must be apostilled: Mexico requires an apostille on any foreign legal document used in a real estate transaction. Budget 2 to 4 weeks for this
• Ignoring the tax reporting: I have seen buyers assume that because their CPA handles their US return, Forms 3520/3520-A are automatically filed. They are not — these are specialized international forms that many domestic CPAs are unfamiliar with
• Using an irrevocable trust when a revocable trust would suffice: Irrevocable trusts add complexity without benefit for most Cabo buyers. The asset protection advantage is minimal for Mexican property because the fideicomiso itself provides substantial protection from US creditor claims

Cost Comparison: Individual vs. Trust vs. LLC

Here is the all-in cost comparison I give clients for a $1 million Cabo property purchase:

Item	Individual	Rev. Trust	LLC
Fideicomiso setup	$2,500	$2,500	$2,500
Additional legal (US attorney)	$0	$1,500–$2,500	$2,000–$3,000
Annual fideicomiso fee	$600–$1,000	$600–$1,000	$600–$1,000
Annual IRS form prep (3520/3520-A)	$500–$1,000	$500–$1,500	$1,000–$2,000
Probate cost at death	$5,000–$15,000	$500–$1,000	$500–$1,000

The math is clear. The trust or LLC structure costs a bit more upfront and annually, but saves your heirs significant money, time, and stress. For properties above $500,000, I recommend the structure to virtually every buyer.

How This Differs From a Mexican SA de CV

I get this question constantly: "Should I just form a Mexican corporation instead?" The answer depends on your goals.

A Mexican SA de CV (corporation) holds property directly — no fideicomiso required. This eliminates the annual bank trust fee. But it introduces Mexican corporate tax obligations, annual audits, SAT (Mexican IRS) compliance, and a 30% corporate tax rate on rental income versus the graduated individual rates you would pay through a fideicomiso. It also complicates the US tax picture because you now own shares in a Controlled Foreign Corporation (CFC), triggering Form 5471 reporting.

For most individual buyers purchasing one or two properties for personal use and rental income, the fideicomiso with a US trust or LLC beneficiary is simpler and cheaper. The SA de CV makes more sense for investors with three or more properties, commercial real estate, or development projects.

Steps to Set Up the Structure

1. Confirm your US trust or LLC is current and in good standing. Get a certificate of good standing from your state, dated within 90 days
2. Obtain an apostille on your trust instrument or LLC operating agreement. This goes through your state's Secretary of State office
3. Select a fideicomiso trustee bank that accepts entity beneficiaries. Confirm in writing before proceeding. See our bank comparison guide
4. Engage a Mexican notario and a US cross-border attorney. The notario handles the Mexican side; the US attorney reviews the trust/LLC structure for tax implications
5. Provide the bank with all entity documentation: trust instrument or operating agreement, EIN letter, certificate of good standing, apostilled copies, certified English-to-Spanish translations
6. Close as normal. The notario prepares the escritura naming the trust or LLC as beneficiary. The SRE permit is obtained. The bank records the fideicomiso. Closing takes the standard 40 to 45 days
7. Set up your IRS reporting. Engage a CPA experienced in international tax reporting for Forms 3520, 3520-A, and FBAR filing
