Selling property in Cabo as an American comes with tax rules that surprise most owners at the closing table. Mexico applies its own capital gains tax. The IRS still wants its piece too. Between these two systems, a poorly planned sale can shave hundreds of thousands of dollars off your profit. Fortunately, with the right structure on day one—and a few smart moves before you list—you can legally minimize what you owe on both sides of the border.
This guide on selling property in Cabo as an American walks through every lever owners can pull, from how you take title to how Mexican residency unlocks the biggest single exemption available. Whether you are buying a turnkey villa in Pedregal, building from scratch in the East Cape, or holding a branded residence at Chileno Bay Resort and Residences, the principles below apply across the Los Cabos market.
The Tax Reality When You Sell in Los Cabos
Selling property in Cabo as an American means navigating two tax systems at once. Mexico treats the sale of real estate as taxable income. The local term is ISR, short for Impuesto Sobre la Renta. Despite the casual use of the phrase “capital gains tax,” this is technically an income tax on the gain you realize when you sell.
For Americans, two tax systems run in parallel. First, Mexico taxes the Mexican-source gain. Second, the United States taxes you on worldwide income, including foreign property sales. Therefore, planning matters from the moment you sign your first purchase agreement—not the day you decide to list.
The Notary Public, known locally as the Notario, calculates and withholds the Mexican tax at closing. Because the Notario is personally liable for the tax owed, expect strict documentation requirements. Sloppy records can cost you the right to deduct legitimate expenses.
Mexico’s Capital Gains Tax: The Two Options
When selling property in Cabo as an American, you face two ways to calculate Mexican capital gains tax. Each path produces dramatically different results depending on your documentation.
Option 1 — Flat 25% on the Gross Sale Price
The first option is simple. Apply 25% to the entire gross sale price. No deductions. No exemptions. This rarely benefits sellers and is almost never the right choice for foreign owners with proper paperwork.
Option 2 — Up to 35% on the Net Gain
The second option is the net-basis calculation. Here, you subtract your adjusted cost basis and qualifying deductions from the sale price. The remaining gain is taxed on a sliding scale from 1.92% to 35%. For most luxury Cabo sales, assume the top 35% rate applies once your gain exceeds 250,000 pesos.
Choosing between the two options depends entirely on documentation. Without strong receipts, the flat 25% can sometimes be lower. With proper paperwork, Option 2 typically wins—often by a wide margin. Your Notario should run both calculations and use the more favorable result.
Buying Smart: How Day-One Decisions Shape Your Future Tax Bill
The biggest tax mistakes for Americans selling property in Cabo happen at the purchase, not the sale. Once your deed is recorded, the numbers on it are locked in. Therefore, plan ahead before you ever close on a Los Cabos home.
Insist on the CFDI at Closing
After December 31, 2013, Mexican tax law requires a digital tax receipt called a CFDI to prove what you paid. Without it, your cost basis can default to zero—even if your deed clearly shows the purchase price. A zero basis means you pay tax on the entire sale price years later, which is the worst possible outcome when selling property in Cabo as an American. Therefore, confirm in writing with your Notario that a proper CFDI is issued in your name and attached to the deed.
Don’t Underdeclare the Purchase Price
Some buyers ask their Notario to record a lower value on the deed to save on the 3% acquisition tax in Baja California Sur. This shortcut is tempting—and dangerously shortsighted. Your future capital gain is calculated against the recorded purchase value, not the actual amount you paid. Saving a few thousand dollars on transfer tax today can cost you tens or even hundreds of thousands when you eventually sell.
Save Every Receipt — And Make Sure They’re Facturas
Mexico recognizes only one form of receipt for tax deductions: the factura. A regular nota or handwritten invoice will not count. Every contractor, supplier, designer, and landscaper must issue a factura in the name of the title holder, referencing the property. Casual workers and small builders often skip facturas; you may pay more by using licensed providers, but that 16% IVA tax pays for itself many times over when you sell.
Building a Home in Los Cabos: Why You Must Manifest Your Construction
Many Americans buy a lot in Los Cabos and build their dream home—or extensively remodel an existing one. If that’s your path, one Spanish word should burn itself into your brain: manifestación. Manifesting your construction is the formal process of registering what you spent so it officially becomes part of your cost basis.
Skip this step, and Mexican tax law treats your construction value as zero. Your bank statements, cancelled checks, and stack of facturas mean nothing without manifestation. This single oversight has cost American owners millions over the years.
How Construction Manifestation Works
The process happens in three stages. First, your contractor submits a Letter of Termination of Works—Aviso de Terminación de Obra—to the local Public Works Department once construction wraps. Second, you take that letter to the Catastro (the cadastral office) to officially register the construction value. Third, the manifested value is added to your land cost shown in the trust deed.
Together, the land plus manifested construction equals your new cost basis. When you eventually sell, this is what gets subtracted from the sale price. Without it, only the original land value counts—and everything else becomes taxable gain.
Fixed Bid vs. Cost-Plus Contracts
Your contract structure also affects your taxes. A fixed-bid contract typically shields you from paying IVA on labor for a personal residence, since Mexican law exempts personal-home construction. A cost-plus contract requires you to track each payment, each factura, and each IVA charge separately. Either way, demand facturas in your name for every payment you make.
Why the Entity Holding Title Matters
When selling property in Cabo as an American, the structure that holds your home is not just a legal formality. It directly determines how—and how much—you pay in tax when you sell.
Americans buying in Los Cabos cannot hold direct title in their personal name because the entire region sits inside Mexico’s “Restricted Zone” (within 50 kilometers of the coast). Two structures unlock ownership for foreigners selling property in Cabo as Americans: a fideicomiso (bank trust) or a Mexican corporation.
The Fideicomiso: Best for Personal Use
A fideicomiso is a 50-year trust held by a Mexican bank acting as trustee. You remain the full beneficial owner with rights to use, lease, modify, sell, and pass the property to heirs. The trust renews for another 50 years and is widely recognized as the standard ownership structure across Los Cabos.
Critically, the IRS issued Revenue Ruling 2013-14 confirming that a standard residential fideicomiso is not a foreign trust for U.S. tax purposes. Therefore, you do not file Form 3520 or Form 3520-A. Setup typically runs $2,000 to $2,500, with annual fees of roughly $500 to $700.
For most American buyers in Cabo, the fideicomiso is the right choice. It preserves your ability to qualify for Mexico’s principal residence exemption—an opportunity a corporation cannot offer.
A Step Further: Naming a U.S. LLC as Your Fideicomiso Beneficiary
Some buyers go further. Instead of being named personally as the beneficiary of the fideicomiso, they form a U.S. LLC—often in Delaware, Wyoming, or Nevada—and name that entity as the beneficiary. When selling property in Cabo as an American, this added layer changes several aspects of how you operate, sell, and report.
Why owners choose this route. The main drivers are asset protection and streamlined U.S. estate planning. The LLC creates a liability shield between the Cabo property and your personal assets. It also simplifies inheritance: ownership transfers through the LLC’s operating agreement, often bypassing Mexican probate entirely. Families with multiple heirs and investors holding more than one Mexican property frequently use this structure.
Does the LLC need U.S. income? No. A U.S. LLC does not need any U.S. income to exist or to hold foreign assets. Single-member LLCs are disregarded for federal tax purposes, which means no separate federal return is required when there is no income. Multi-member LLCs default to partnership treatment and file Form 1065 only when there is activity to report. The LLC simply needs to comply with its state of formation—usually an annual fee between $50 and $800, a registered agent, and basic recordkeeping to preserve the liability shield. Delaware, Wyoming, and Nevada remain popular precisely because their fees and reporting burdens stay low.
How this affects your Mexican capital gains. Here’s where the structure gets nuanced. Mexico generally does not treat a U.S. LLC as a flow-through entity. Instead, Mexico often views the LLC as the actual owner of the fideicomiso beneficial interest—not the individual member behind it. That distinction matters most when you try to claim the principal residence exemption. The 700,000 UDI exemption requires individual ownership by a Mexican tax resident with an RFC. An LLC cannot qualify.
Therefore, Americans who plan to relocate, obtain residency, and use the property as a primary home should think carefully before titling through an LLC. You may be trading the most valuable Mexican exemption for U.S. asset protection. For pure vacation homes or rental investments where the residency exemption was never on the table, the trade is often worth it.
U.S. reporting stays manageable. On the U.S. side, the LLC layer adds little complexity. The fideicomiso itself remains a nominee arrangement under IRS Revenue Ruling 2013-14, so no Form 3520 is triggered. The LLC obtains an EIN. FBAR and Form 8938 thresholds still apply to the individual member based on the value of Mexican accounts and assets the LLC holds.
Bottom line. Use the LLC-beneficiary structure for investment properties where asset protection or multi-owner clarity matters more than the Mexican residence exemption. Hold the fideicomiso personally when residency planning and the 700,000 UDI exemption are central to your strategy. When selling property in Cabo as an American, the right title decision flows directly from what you intend to do with the home.
The Mexican Corporation: For Commercial Use
A Mexican corporation can hold property anywhere in Mexico, including the Restricted Zone, when the use is commercial rather than residential. This route makes sense for serious rental businesses, hotel operators, or investors holding multiple income-producing properties.
However, a corporation cannot claim the personal residence capital gains exemption. It also requires monthly accounting, annual filings, and roughly $2,000 to $5,000 a year in compliance costs. For a single vacation home, the math rarely works in the corporation’s favor.
A Word on Self-Directed IRAs
Some sophisticated investors use a U.S. self-directed IRA to fund a U.S. LLC, which then capitalizes a Mexican corporation to hold the property. This advanced structure can offer tax-deferred growth on rental income for the right investor. However, the complexity and ongoing costs are substantial. Pursue this only with experienced cross-border counsel.
The Power of Mexican Residency for Reducing Capital Gains
Of every tax-saving lever available when selling property in Cabo as an American, Mexican residency is the most powerful. The reason is simple: only Mexican tax residents can claim the principal residence exemption that can wipe out capital gains on a qualifying sale.
How the Exemption Works
Article 92, Fraction XIX of Mexico’s Income Tax Law exempts up to 700,000 UDIs of gain from the sale of your primary residence. UDIs are inflation-indexed investment units; as of late 2025, 700,000 UDIs equal roughly $313,000 USD. To qualify, all of the following must be true:
- You hold legal Mexican residency (temporal or permanente)
- You have a Mexican tax ID (RFC)
- The property is your primary residence
- You can prove residency through utility bills, bank statements, or tax filings in your name at the address
- The land does not exceed three times the size of the construction (in square meters)
- You have not used the exemption in the past three years
Co-titling with a spouse who also holds Mexican residency and an RFC can effectively double the exemption to roughly $626,000 USD. For families, this single planning move can eliminate Mexican capital gains tax on a substantial Cabo sale.
Temporal vs. Permanente Residency
Mexico’s tax law does not explicitly specify whether temporal or permanent residency is required for the exemption. In practice, Notarios apply their own discretion. Some recognize residente temporal status; others require residente permanente. Therefore, if your Notario refuses, another may approve—shopping among Notarios is legitimate and common in Los Cabos.
How to Qualify Financially for Residency
Mexico offers residency through several financial pathways, including income, savings, or property ownership above set thresholds. As of 2026, a property investment of roughly $300,000 USD in Mexico is one route. Specifically, the financial bar shifts annually with the UMA (Mexico’s official measurement unit), so always check current rules through a Mexican consulate or immigration advisor before applying.
Importantly, simply owning a Cabo home above the threshold can be enough to qualify—turning your purchase into both a lifestyle move and a tax-planning move.
The U.S. Side: How to Avoid Double Taxation
Here’s the part most American sellers miss until the day they file their U.S. return. Selling property in Cabo as an American means you must also report the gain to the IRS. Because the United States taxes citizens and green card holders on worldwide income, your Cabo sale appears on Form 1040, Schedule D, and Form 8949—regardless of whether you also pay Mexican tax.
The Foreign Tax Credit Is Your Best Friend
Article 24 of the U.S.-Mexico Income Tax Convention requires both countries to provide relief from double taxation. In practice, you claim a dollar-for-dollar Foreign Tax Credit on IRS Form 1116 for Mexican ISR paid at closing. If your Mexican tax exceeds your U.S. liability, the excess generally carries back one year and forward up to ten years.
Critically, the credit is per-country and per-category. Capital gains have their own basket, so credits from Mexican wages or rental income don’t combine with property-sale credits. Work with a cross-border CPA to structure the claim correctly and capture every dollar of available credit.
The Section 121 Exclusion for U.S. Tax
If your Cabo home was also your primary residence under U.S. tax rules—two of the last five years, per the IRS facts-and-circumstances test—you may still claim the U.S. Section 121 exclusion. That exclusion shields up to $250,000 of gain for single filers and $500,000 for married couples filing jointly, even though the home sits in Mexico.
Combine Section 121 with the Foreign Tax Credit and Mexico’s residency exemption, and many American sellers walk away with little or no tax owed on either side of the border.
What About a 1031 Exchange?
A common question. Unfortunately, the answer is no. Section 1031 like-kind exchanges only work between U.S.-situated properties. You cannot 1031 a Cabo property into a U.S. one, or vice versa. Treat cross-border deferral as off the table.
Required IRS Forms to Remember
- FBAR (FinCEN 114): Required if any Mexican bank account, including escrow tied to the sale, exceeds $10,000 USD at any point in the year.
- Form 8938: Required if foreign financial assets cross certain higher thresholds (varies by filing status and residency).
- Form 8833: Required when you take certain treaty-based positions on your return.
- Form 1116: Required to claim the Foreign Tax Credit for Mexican ISR paid.
- Form 8949 and Schedule D: Required to report the sale itself.
Skipping FBAR triggers some of the steepest penalties in U.S. tax law. Do not gamble on this one.
The Currency Game: How Pesos Affect Your Cabo Sale
One often-overlooked wrinkle of selling property in Cabo as an American is the currency conversion. Most Cabo transactions are quoted in U.S. dollars. Mexico, however, calculates capital gains exclusively in pesos. Your purchase price is converted to pesos at the closing-date exchange rate; your sale price is converted at a different rate years later. Therefore, a stable dollar value can still produce a large peso gain—or vice versa.
When the peso weakens against the dollar over your ownership period, your peso-denominated gain grows even if your dollar gain stays flat. Conversely, peso strength can shrink your taxable Mexican gain. Sellers who time their exit during periods of peso strength sometimes save substantially. This is one reason the right local agent matters: market timing in Cabo is partly a currency play.
Top Tips for Maximizing Savings When Selling Property in Cabo as an American
The following moves separate well-planned American sellers from those who leave money on the table.
- Lock in your CFDI at purchase. No CFDI, no cost basis. Confirm this requirement in writing with your Notario before closing.
- Record the full purchase price. Resist temptations to lower the deed value to save on acquisition tax. The future capital gains hit dwarfs the savings.
- Pull every factura. No factura, no deduction. This applies to construction, remodels, agent commissions, legal fees, and most closing costs.
- Manifest your construction. If you build or remodel, file the Aviso de Terminación de Obra and update the Catastro. Otherwise, your construction value disappears from your cost basis.
- Apply for an RFC early. Without a Mexican tax ID, the primary residence exemption is unavailable—even if you otherwise qualify as a resident.
- Pursue residency before you sell. Temporal residency at minimum unlocks the exemption pathway and access to RFC issuance.
- Co-title with your spouse when both can qualify as residents. Two exemptions are better than one, and the combined shield can exceed $600,000 USD of gain.
- Choose your Notario carefully. Some are conservative on deductions and exemptions; others apply the rules more liberally. The choice directly affects your bottom line.
- Track facturas and CFDIs in both USD and pesos. Cross-border CPAs need both figures to coordinate Mexican and U.S. reporting.
- Time your exit thoughtfully. Peso strength reduces your Mexican peso-denominated gain. Residency status reduces the rate. Combine both when possible.
- File every required U.S. form. FBAR, Form 8938, Form 1116, Form 8949, and Schedule D each matter. The penalties for skipping are often worse than the tax itself.
- Engage cross-border professionals. A Mexican Notario, a Mexican accountant, and a U.S. CPA experienced with the U.S.-Mexico treaty form your essential team. Add a local real estate specialist to coordinate everything.
Plan the Sale Before You Buy the Property
Here’s the single most important takeaway from this guide on selling property in Cabo as an American. Every smart move described above is easier—and cheaper—when made at the purchase stage.
