Tax Obligations for US Citizens Owning Property in Mexico
Tax Obligations for US Citizens Owning Property in Mexico
Owning property in Mexico is a rewarding investment — but it comes with a set of tax obligations that stretch across two countries. Many US citizens focus entirely on Mexican requirements and overlook what they owe the IRS. Others do the opposite. Getting both sides right is essential to staying compliant and avoiding penalties that can dwarf the original tax liability.
This guide covers the key obligations on both sides of the border as of 2026.
Your US Tax Obligations: The Long Arm of the IRS
The United States taxes its citizens on worldwide income, regardless of where they live or where the income is earned. Owning property in Mexico does not exempt you from US reporting.
FBAR: Report of Foreign Bank and Financial Accounts
If your Mexican bank account balance exceeds $10,000 USD at any point during the calendar year, you are required to file a FinCEN Form 114 (commonly called the FBAR) with the Financial Crimes Enforcement Network. This is separate from your tax return and is filed electronically by April 15 (with an automatic extension to October 15).
The penalties for willful non-filing are severe — up to $100,000 or 50% of the account balance per violation. Even non-willful violations can cost $10,000 per year.
Form 8938: FATCA Reporting
Under the Foreign Account Tax Compliance Act (FATCA), US taxpayers with significant foreign financial assets must file Form 8938 with their federal tax return. The thresholds vary:
- Single filers living in the US: Foreign assets exceeding $50,000 at year-end or $75,000 at any point during the year
- Married filing jointly, US residents: $100,000 / $150,000
- Taxpayers living abroad: Thresholds are higher ($200,000 / $300,000 for single filers)
A Mexican fideicomiso (bank trust) holding your property may constitute a foreign financial asset for FATCA purposes. This is an area where professional guidance is critical, as the rules have significant gray areas.
Rental Income
If you rent your Mexican property — even occasionally on platforms like Airbnb or VRBO — that income must be reported on your US federal return. You can deduct eligible expenses (mortgage interest, property management fees, maintenance, depreciation) to offset the income. Keep careful records in both USD and MXN.
Mexican Tax Obligations
ISR: Impuesto Sobre la Renta (Income Tax)
Mexico’s federal income tax applies to income generated in Mexico, including rental income from Mexican property. Non-resident owners have two options for calculating tax on rental income:
- Option 1: Flat 25% tax on gross rental income (no deductions)
- Option 2: 35% on net income after authorized deductions
Most property managers will withhold Mexican tax on rental payments to foreign owners. You must ensure this is being done correctly and that you receive tax receipts (constancias de retención).
Predial: Property Tax
Mexico’s annual property tax (predial) is assessed by the municipality where the property is located. Rates are low by North American standards — typically 0.1–0.3% of the assessed (catastral) value, which is often significantly below market value. Most municipalities offer discounts (10–20%) for early payment in January.
Keeping predial current is important: unpaid taxes accrue interest and can eventually result in a lien on the property.
Capital Gains on the Sale of Your Property
When you eventually sell, you will face capital gains obligations in both countries.
Mexican Capital Gains (ISR por Enajenación)
Mexico taxes capital gains on real estate sales to non-residents at 25% of the gross sale price or 35% of the net gain (your choice). A notary public calculates and withholds the tax at closing.
However, if you have Mexican residency and the property was your primary residence, you may qualify for an exemption up to approximately 700,000 UDIs (roughly $5.5–6 million MXN as of 2026). This exemption is subject to conditions and must be properly documented.
US Capital Gains
The IRS will tax your gain on the sale as well. Your cost basis is generally your original purchase price plus documented improvements, converted to USD at the historical exchange rates. Any Mexican tax paid on the sale can be claimed as a foreign tax credit on your US return to offset what you owe the IRS.
The US-Mexico Tax Treaty: Avoiding Double Taxation
The United States-Mexico Income Tax Treaty provides mechanisms to avoid being taxed twice on the same income. Key provisions include:
- Foreign tax credits allow you to offset US tax liability with taxes already paid to Mexico
- Reduced withholding rates on certain income categories
- Tie-breaker rules for determining tax residency
The treaty is a valuable tool, but applying it correctly — especially at the intersection of rental income, capital gains, and entity structures — requires expertise in both tax systems.
Canadian Citizens: Similar but Different
Canadian property owners in Mexico face parallel obligations under the Canada Revenue Agency (CRA) rules. Canada also taxes residents on worldwide income. FINTRAC reporting requirements apply to certain financial accounts, and the Canada-Mexico Tax Convention provides similar protections against double taxation. The specifics differ from US rules, so Canadian owners should seek advice from professionals familiar with both CRA requirements and Mexican tax law.
Practical Steps to Stay Compliant
- Open a Mexican RFC (Registro Federal de Contribuyentes) — Mexico’s tax ID. This is required for many property-related transactions.
- Work with a bilingual accountant who files in both jurisdictions.
- Maintain meticulous records: all purchase documents in both currencies, improvement receipts, rental income records, and tax payment confirmations.
- Review your obligations annually — tax rules in both countries evolve.
