Moving to Mexico as a U.S. citizen offers an exciting opportunity to embrace a vibrant culture, warm climate, and a lower cost of living. However, navigating the tax obligations as a U.S. expat in Mexico can feel overwhelming due to the complexities of complying with both U.S. and Mexican tax systems. The good news? The U.S.-Mexico Income Tax Convention, signed in 1992, helps prevent double taxation, ensuring you’re not unfairly taxed on the same income by both countries. At Beacon Hill Wealth Management, we specialize in guiding U.S. expats through cross-border tax and investment challenges, and we’re here to make this process clear and manageable.

This comprehensive guide breaks down how U.S. expats living permanently in Mexico are taxed, covering key considerations, tax obligations, and strategies to optimize your financial situation. Whether you’re a retiree enjoying the beaches of Puerto Vallarta or a professional working in Mexico City, understanding these rules will help you stay compliant and make informed financial decisions.

Understanding U.S. Tax Obligations for Expats in Mexico

As a U.S. citizen or green card holder, you’re subject to worldwide income taxation, regardless of where you live. This means you must report all income—whether earned in the U.S., Mexico, or elsewhere—to the IRS. Here’s what you need to know:

1. Filing U.S. Tax Returns

• Who Must File: If you meet the IRS income thresholds (e.g., $13,850 for single filers or $27,700 for married filing jointly in 2024), you must file a U.S. tax return (Form 1040). Even if your income is below these thresholds, you may need to file to claim refunds or comply with reporting requirements.

• Deadlines: Expats receive an automatic two-month extension, moving the filing deadline to June 15. However, any taxes owed are due by April 15 (automatic extensions may apply) unless you file for an extension (Form 4868), which extends the filing deadline to October 15.

• Key Forms:

  • Form 1040: Your main U.S. tax return.

  • Form 2555: To claim the Foreign Earned Income Exclusion (FEIE) or Foreign Housing Exclusion.

  • Form 1116: To claim the Foreign Tax Credit (FTC) for taxes paid to Mexico.

2. Foreign Earned Income Exclusion (FEIE)

The FEIE allows you to exclude a portion of your foreign-earned income from U.S. taxation. For 2024, the exclusion amount is $126,500 per person. To qualify, you must meet one of two tests:

• Physical Presence Test: Spend at least 330 full days outside the U.S. in a 12-month period.

• Bona Fide Residence Test: Establish that you’re a resident of Mexico for an uninterrupted period that includes an entire tax year.

Note: The FEIE only applies to earned income (e.g., wages, self-employment income), not passive income like investments, pensions, or Social Security.

3. Foreign Tax Credit (FTC)

The FTC allows you to offset U.S. taxes with taxes paid to Mexico on the same income, preventing double taxation. Per the U.S.-Mexico Tax Treaty (Article 24), you can claim a credit for Mexican income taxes paid, ensuring you don’t pay twice on the same income. The FTC is often more beneficial than the FEIE for expats with high income or passive income sources, as it applies to all types of income.

4. Foreign Bank Account Reporting (FBAR)

If you have foreign financial accounts (e.g., Mexican bank accounts, investments) with an aggregate value exceeding $10,000 at any point during the year, you must file an FBAR (FinCEN Form 114). The deadline is April 15, with an automatic extension to October 15. Failure to file can result in penalties up to $10,000 or more for non-willful violations.

5. FATCA Reporting

Under the Foreign Account Tax Compliance Act (FATCA), you must report foreign financial assets exceeding certain thresholds (e.g., $200,000 for single filers living abroad at year-end or $300,000 at any point during the year) on Form 8938. This requirement overlaps with FBAR but has different thresholds and details.

Mexican Tax Obligations for U.S. Expats

Mexico taxes residents on their worldwide income, similar to the U.S. If you’re a permanent resident in Mexico (e.g., holding a residente permanente visa or spending more than 183 days in the country annually), you’re considered a tax resident. Here’s how Mexico’s tax system applies to U.S. expats:

1. Determining Tax Residency

Per Article 4 of the U.S.-Mexico Tax Treaty, you’re a Mexican tax resident if you have a permanent home in Mexico, stronger personal and economic ties (center of vital interests), or spend more than 183 days in Mexico annually. If you’re a resident of both countries, the treaty provides tie-breaker rules to determine your primary tax residency.

2. Mexican Income Tax Rates

Mexico’s income tax is progressive, with rates ranging from 1.92% to 35% in 2024, depending on your income level. For example:

• Income up to MXN 8,952.49: 1.92%

• Income from MXN 103,550.45 to MXN 1,235,243.24: 30%

• Income above MXN 1,235,243.24: 35%

Non-residents are taxed only on Mexican-sourced income at flat rates (e.g., 25% on rental income or 30% on capital gains, unless treaty provisions apply).

3. Types of Income Taxed

• Earned Income: Wages, salaries, and self-employment income are taxed at progressive rates.

• Investment Income: Dividends, interest, and capital gains are taxable, but the U.S.-Mexico Tax Treaty (Articles 10-13) limits Mexico’s taxing rights. For example:

  • Dividends: Mexico can impose a withholding tax of 10% (or 5% if you own at least 10% of the paying company’s voting stock).

  • Interest: Mexico can tax interest at rates from 4.9% to 15%, depending on the source (e.g., bank loans, bonds).

  • Royalties: Mexico imposes a 10% withholding tax, but certain royalties may be exempt.

• Rental Income: Income from renting property in Mexico is taxed at 25% for non-residents, but residents can deduct expenses and are taxed at progressive rates.

• Pensions and Social Security: Per Article 19, U.S. pensions and Social Security benefits are generally taxable only in the U.S., protecting retirees from Mexican taxation.

4. Mexican Assets Tax

Mexico’s assets tax (impuesto sobre activos) may apply to U.S. expats who own significant assets in Mexico (e.g., real estate, business assets). However, the U.S.-Mexico Tax Treaty (Protocol 1, Paragraph 3) ensures that this tax is waived or credited if it negates treaty benefits, such as exemptions on U.S.-sourced income.

The U.S.-Mexico Tax Treaty: Preventing Double Taxation

The U.S.-Mexico Income Tax Convention, effective since January 1, 1994, is designed to avoid double taxation and prevent tax evasion. Key provisions include:

• Relief from Double Taxation (Article 24): The U.S. allows a Foreign Tax Credit for Mexican taxes paid, and Mexico may exempt or credit U.S.-sourced income to avoid taxing it twice.

• Reduced Withholding Rates: The treaty lowers withholding taxes on dividends (5-10%), interest (4.9-15%), and royalties (10%), compared to Mexico’s domestic rates.

• Permanent Establishment (Article 5): U.S. businesses operating in Mexico are taxed only on profits attributable to a “permanent establishment” (e.g., a fixed place of business), reducing tax exposure for remote workers or small operations.

• Exchange of Information (Article 27): The U.S. and Mexico share tax information to ensure compliance, expanded by the 1994 Additional Protocol to cover all levels of government.

By leveraging the treaty, you can minimize your tax burden and ensure compliance with both countries’ laws. Consulting a cross-border tax professional is essential to maximize these benefits.

Key Tax Planning Strategies for U.S. Expats in Mexico

To optimize your tax situation, consider these strategies tailored for U.S. expats in Mexico:

1. Maximize Tax Credits and Exclusions

• Use the Foreign Tax Credit to offset U.S. taxes with Mexican taxes paid, especially for investment or rental income.

• Claim the Foreign Earned Income Exclusion if you earn wages or self-employment income in Mexico, but evaluate whether the FTC is more beneficial for your situation.

• Combine the Foreign Housing Exclusion with the FEIE to exclude housing costs (up to $39,360 in 2024 for high-cost areas like Mexico City).

2. Manage Investment Accounts

• U.S. Brokerage Accounts: Most U.S. brokers cannot service non-residents, so consider transferring investments to a cross-border advisor that can help. Avoid using a U.S. relative’s address to maintain accounts, as this violates securities laws.

• Capital Gains: Per Article 13, gains from selling Mexican real estate or significant shares in Mexican companies are taxable in Mexico. Plan sales strategically to minimize tax liability, and use the FTC to offset U.S. taxes.

• Mexican Investments: Be cautious with Mexican mutual funds (fondos de inversión), as they may be treated as Passive Foreign Investment Companies (PFICs) by the IRS, triggering complex reporting and high taxes.

3. Retirement Accounts

• Traditional IRAs: You can keep your IRA in the U.S., but withdrawals are taxable in the U.S. and potentially in Mexico unless exempt under the treaty. Consider transferring to a Mexican-compliant account with a cross-border advisor to simplify management.

• Roth IRAs: Roth withdrawals are generally tax-free in the U.S., but Mexico may tax them unless you file a treaty-based election. Consult a professional to ensure compliance.

• Social Security: Per Article 19, U.S. Social Security benefits are taxable only in the U.S., protecting retirees from Mexican taxation.

4. Real Estate Ownership

• Primary Residence: Mexico offers a capital gains exemption for selling your primary residence if held for at least three years. For non-residents, a 25% withholding tax applies unless you elect to be taxed at progressive rates.

• Rental Properties: Deduct expenses (e.g., maintenance, property taxes) to reduce taxable rental income in Mexico. Use the FTC to offset U.S. taxes on the same income.

5. Business and Self-Employment

• Self-Employment: Self-employed expats pay Mexican income tax at progressive rates and may owe self-employment tax in the U.S. (15.3% on net earnings). The U.S.-Mexico Totalization Agreement may exempt you from U.S. self-employment tax if you contribute to Mexico’s social security system.

• U.S. LLCs: LLCs are not tax-efficient for Mexican residents due to mismatched tax treatment. Consider restructuring into a Mexican entity or winding up the LLC before moving.

• Permanent Establishment: If you operate a business in Mexico, ensure it doesn’t create a permanent establishment to avoid additional taxation (Article 5).

6. Trusts and Estate Planning

• U.S. Trusts: Trusts are common in the U.S. but complex in Mexico. Mexican tax authorities may treat trust income as taxable, even if it’s not distributed. Plan trust distributions before moving to minimize tax exposure.

• Mexican Fideicomisos: Foreigners owning coastal or border property in Mexico often use a fideicomiso (trust). These are not taxable in Mexico but must be reported on FBAR and FATCA forms if they meet thresholds.

Common Tax Pitfalls to Avoid

Navigating dual tax systems can lead to costly mistakes. Here are pitfalls to watch out for:

• Missing FBAR or FATCA Deadlines: Failure to report foreign accounts can result in severe penalties, even if no tax is owed.

• Misapplying the FEIE: Claiming the FEIE on passive income (e.g., dividends, pensions) is incorrect and can trigger IRS audits.

• Ignoring Treaty Benefits: Not leveraging the U.S.-Mexico Tax Treaty can result in overpaying taxes. For example, failing to claim reduced withholding rates on dividends or interest.

• Improper Trust Reporting: U.S. trusts or Mexican fideicomisos must be reported correctly to avoid penalties.

• Assuming Tax-Free Withdrawals: Roth IRA or pension withdrawals may be taxable in Mexico without proper treaty elections.

3. Plan Before Moving: Review your investments, retirement accounts, and business structures before relocating to minimize tax complexity.

4. Monitor Exchange Rates: Use the correct year-end exchange rates for FBAR reporting (e.g., 2024 rates are available at www.beaconhillwm.ca/fbar-exchange-rates).
