US Expats in Mexico: FEIE, Rental Properties, and Cross-Border Tax Planning

Mexico has become one of the fastest-growing destinations for American expats. The proximity to the US, overlapping time zones, lower cost of living, and the rise of remote work have created a wave of Americans settling in Mexico City, Guadalajara, San Miguel de Allende, Puerto Vallarta, Mérida, and dozens of other cities.

The tax situations I see from Mexico-based clients are often the most complex in my practice — not because Mexico is inherently complicated, but because these clients tend to have multiple income streams spanning both countries. A W-2 from a US employer. Freelance clients paying 1099. A rental property back in California or Austin. Maybe a 401k distribution or California unemployment from a prior job.

Let me walk through how all of this fits together.

A Real Client Case Study

To ground this in reality, here's a composite case based on actual client situations (details anonymized):

Client profile: Single, moved from California, CA to Mexico City in early 2024. Working remotely for a US tech company (W-2), doing freelance design work on the side (Schedule C), maintaining an California rental property (Schedule E), received California unemployment early in the year (1099-G), and took a small 401k distribution from a previous employer (1099-R).

The result after proper tax planning:

• Federal refund: $7,417
• California refund: $3,536

Without claiming the FEIE and structuring deductions properly, this client would have owed approximately $4,800 federal and received only a small California refund. The FEIE alone accounted for over $10,000 in savings.

FEIE from Mexico: The Foundation

The FEIE works the same from Mexico as from any other foreign country. Your eligibility depends on two things:

1. Your Tax Home Must Be in Mexico

Your tax home is where you regularly work — not where you maintain a family home or where your employer is. If you live and work in Mexico City, your tax home is Mexico City. The IRS looks at:

• Where is your principal place of business?
• Where do you regularly live?
• Do you have a closer connection to Mexico than to the US?

Proof points: Mexican temporary or permanent residency card, lease agreement, utility bills, RFC (Registro Federal de Contribuyentes — Mexico's taxpayer ID), Mexican bank account.

2. Meet the Bona Fide Residence or Physical Presence Test

Physical Presence Test: Be outside the US for 330 full days in any 12-month period. With Mexico's proximity, this test requires discipline. A quick weekend in Texas or a week-long family visit eats into your 35-day allowance fast.

Bona Fide Residence Test: Establish genuine residence in Mexico for an uninterrupted period that includes a full calendar year. This is often the better test for Mexico-based expats because:

• Cross-border trips to the US are common (family, shopping, medical)
• You may exceed 35 US days easily
• Mexican residency documentation is strong (INM residency card, RFC, CURP)

FEIE Exclusion Amounts

For our client earning $95,000 W-2 + $22,000 freelance = $117,000 in earned income — the entire amount is excluded via FEIE.

The Foreign Housing Exclusion: Mexico City Rent

If you're paying rent in Mexico (or a mortgage on a home you own there), the Foreign Housing Exclusion can exclude additional income beyond the base FEIE amount.

How It Works

The exclusion covers "qualified housing expenses" above a base amount:

Mexico City Example

That's an additional $4,220 excluded from taxable income — on top of the standard FEIE limit. At a 22% marginal rate, that's roughly $930 in additional savings.

Note: Mortgage principal and furniture purchases don't count. Rent, utilities, and renter's insurance do.

Freelance and Contract Income from Mexico

If you do freelance or contract work while living in Mexico, that income goes on Schedule C and is subject to:

1. Federal income tax — but excluded via FEIE (it's earned income)
2. Self-employment tax — 15.3% on net income, and FEIE does NOT exclude this

The SE Tax Reality

For our client with $22,000 in freelance income:

The FEIE eliminates federal income tax on this income but the $3,109 in SE tax is still owed. This is unavoidable unless Mexico and the US had a totalization agreement (they do — the US-Mexico totalization agreement took effect in 2005). If you're contributing to IMSS (Mexico's social security system) through your Mexican employer or voluntarily, you may be able to claim exemption from US SE tax using Form 8854 or Certificate of Coverage. This is worth investigating if you have significant self-employment income.

Deducting Business Expenses

Don't forget to deduct legitimate business expenses on Schedule C before calculating SE tax:

• Computer and software
• Internet (business portion)
• Coworking space membership
• Professional development
• Travel for client meetings
• Home office deduction (if you work from home in Mexico)

US Rental Property While Living Abroad

This is where Mexico expat returns get interesting. Many of my clients kept their US home and converted it to a rental when they moved. Here's what you need to know.

Schedule E Reporting

Rental income and expenses are reported on Schedule E. This includes:

Depreciation: Claim It or Lose It

Residential rental property is depreciated over 27.5 years using straight-line depreciation. This is not optional.

Example: You purchased an California condo for $550,000. The land is worth $150,000, so the depreciable basis is $400,000.

Annual depreciation: $400,000 / 27.5 = $14,545 per year

This is a powerful deduction. On a property generating $36,000 in gross rent with $24,000 in expenses, the $14,545 depreciation deduction creates a paper loss — even though you're cash-flow positive.

Critical point: Even if you don't claim depreciation, the IRS will tax you on it at sale as if you did. This is the "allowed or allowable" rule. Always claim your depreciation. Not claiming it gives you the worst of both worlds — no current deduction, but full recapture at sale.

Rental Income Does NOT Qualify for FEIE

This catches people off guard. Rental income is passive income, not earned income. It cannot be excluded via the FEIE.

However, between mortgage interest, property taxes, management fees, insurance, and depreciation, many rental properties show a net loss for tax purposes — meaning no additional tax owed on the rental.

State Tax Obligations: The California Problem

If you moved from California, pay close attention. California is one of the most aggressive states for taxing former residents and California-source income.

California-Source Income

If you have any income sourced to California, you must file a California nonresident return (Form 540NR) regardless of where you live. California-source income includes:

• Rental income from California property
• Wages from a California employer (even if you work remotely)
• California unemployment (1099-G)
• Capital gains from selling California property
• Income from a California-based business

California Does NOT Recognize the FEIE

This is a major point. California does not follow the federal FEIE for California-source income. If your employer is in California and you're performing services for them remotely from Mexico, California may argue that income is California-source and tax it — even if you've excluded it on your federal return.

The analysis depends on whether the income is truly California-source or assigned to your new location. If you're working remotely and never set foot in California, there's a strong argument that the income is Mexico-source. But California's Franchise Tax Board (FTB) is known to push back.

Severing California Residency

To stop California from taxing your worldwide income, you need to establish that you're no longer a California resident. The FTB looks at:

• Did you change your driver's license?
• Did you update your voter registration?
• Where is your bank account?
• Where do you receive mail?
• Do you maintain a home in California available for your use?
• Where are your professional licenses registered?
• Where is your church, gym, doctor?

Having a rental property in California doesn't automatically make you a resident — but if you keep a room available for your own use, or maintain too many California connections, the FTB can challenge your residency departure.

Our Client's California Situation

For the client earning $95,000 (W-2) + $22,000 (freelance) + $8,400 (California rental) + $4,200 (CA unemployment):

The California tax was limited to the rental income and unemployment — resulting in a refund of $3,536 compared to the estimated taxes paid.

401k Distributions While Abroad

Our client also took a $6,500 distribution from a former employer's 401k. Here's how this plays:

• 401k distributions are taxable income but are NOT earned income
• They do not qualify for the FEIE
• They are subject to federal income tax at ordinary rates
• If taken before age 59.5, an additional 10% early withdrawal penalty applies
• The custodian typically withholds 20% for federal tax

However, if your total taxable income after the FEIE is low, the 401k distribution may fall into the 10% or 12% bracket — much better than if you were also paying tax on your earned income.

Practical Tips for Mexico-Based Expats

Document Everything

1. Keep a travel log — every time you cross the border, log the date, direction, and purpose
2. Save your INM residency card — proof of legal status in Mexico
3. Keep your lease and utility bills as proof of foreign residence
4. Track your RFC — Mexico's taxpayer ID shows you're engaged in the Mexican system
5. Save flight and border crossing records — CBP records are available at i94.cbp.dhs.gov

Watch Your US Days

Mexico's proximity makes it easy to pop over the border. If you're using the Physical Presence Test (330 days), every day trip to Texas, Arizona, or California counts as a US day. Those weekend shopping trips to McAllen add up fast.

Even under the Bona Fide Residence Test, excessive US presence can undermine your claim. My general guidance: keep US visits under 60 days per year if possible, and always have a clear reason for each trip.

Consider Mexican Tax Obligations

Mexico taxes residents on worldwide income. If you've been in Mexico long enough to be considered a tax resident (generally 183 days in a calendar year, or if your center of vital interests is in Mexico), you may owe Mexican taxes too.

The US-Mexico tax treaty and the Foreign Tax Credit (Form 1116) prevent double taxation. If you pay Mexican ISR (income tax), you can credit that amount against your US tax liability dollar-for-dollar.

This is a two-country tax planning exercise. Getting it wrong means paying more tax than necessary in one country or the other — or both.

The Bottom Line

Mexico-based expats have enormous tax savings opportunities, but the complexity is real. Between the FEIE, rental properties, state tax obligations, self-employment tax, and cross-border considerations, your return isn't something TurboTax is equipped to handle.

Every component of your tax picture interacts with every other component. The FEIE affects your bracket for rental income. The rental loss may offset 401k income. California taxes operate on completely different rules than the federal return. The Foreign Housing Exclusion adds another layer.

This is exactly the kind of multi-jurisdiction, multi-income-source return that FileAbroad handles every day.
