Mexico tax residency: temporary and permanent resident implications

Mexico uses a center-of-vital-interests test rather than a simple day-count rule. You are Mexican tax-resident if your permanent home is in Mexico, or — if you have permanent homes in multiple countries — if your center of vital interests (defined as 50%+ of your income from Mexican sources, or your principal center of professional activity) is in Mexico. Holding a Temporary or Permanent Resident visa does not by itself make you Mexican tax-resident, but it strongly raises the question. Mexican tax residents are taxed on worldwide income at progressive rates up to 35%.

The Mexican residency test

Under Article 9 of the Código Fiscal de la Federación, you are Mexican tax-resident if:

1. You have a permanent home in Mexico. A residence available to you year-round.
2. If you have permanent homes in both Mexico and another country, you are still Mexican tax-resident if either:
   • More than 50% of your total income in the calendar year comes from Mexican sources, OR
   • Your principal center of professional activities is in Mexico.

There is no explicit 183-day day-count rule in Mexican law (unlike most other countries). Day-counts feed into the “permanent home” and “principal center” tests indirectly, but they don’t trigger residency on their own.

What “permanent home” means in practice

The Mexican concept of permanent home (casa habitación) is broader than tourist accommodation:

• Owned or long-term rented residence. Year-round availability is the key factor.
• Address registered with SAT (the tax authority) — registering for an RFC (taxpayer ID) at a Mexican address creates a presumption of Mexican residence.
• Family residence. Mexican-resident spouse + minor children at a Mexican address creates strong residence indicators even if you personally travel.

A 4-month rental for a winter stay is generally not a permanent home. A year-round lease that you renew is.

The Resident-visa connection

Mexico’s main long-stay visas don’t directly trigger tax residency, but they affect the analysis:

• Tourist FMM (up to 180 days, per officer’s discretion — increasingly less than 180): generally non-resident.
• Temporary Resident Visa (1 year initially, renewable up to 4 years): designed for people who will spend significant time in Mexico. Implies — but doesn’t prove — Mexican residence.
• Permanent Resident Visa (indefinite): strongly implies Mexican residence, especially combined with a Mexican home.

Holding the visa is necessary for long-stay legal presence, but it’s the center-of-vital-interests + permanent home combination that determines tax residency. A Temporary Resident who spends 4 months in Mexico annually with no Mexican home and all foreign income is not automatically a Mexican tax resident.

That said: SAT and the Mexican immigration system are increasingly cross-referenced. Holding a Temporary or Permanent Resident card while denying tax residence requires solid documentation.

What’s taxed under Mexican residency

A Mexican tax resident is taxed on:

• Worldwide income at progressive ISR rates: 1.92% to 35% (top rate at MXN 4.5m+ annual income — roughly USD $225k+).
• Capital gains at ordinary rates (no separate capital-gains regime; some exemptions for personal residence sale).
• Dividends at an additional 10% (on top of corporate tax already paid).
• Interest at progressive rates, with withholding rates on financial-institution interest.
• IVA (VAT) at 16% on most goods and services.

Mexican residents must also file annual declarations to SAT and may need to declare foreign accounts and assets above thresholds.

What’s taxed for non-residents

Non-residents are taxed only on Mexican-source income, generally via withholding:

• Mexican real estate rentals: 25% withholding on gross (or net rate via election).
• Mexican-employment income: progressive rates up to 30% (lower top rate than residents).
• Capital gains on Mexican-sourced assets: 25% withholding on gross or 35% on net.
• Dividends from Mexican companies: 10% withholding.

For most expats with all-foreign income who stay non-resident, the Mexican tax burden is effectively zero.

When Mexican tax residency starts and ends

Residency starts the day you meet the test (typically the date you establish a permanent home in Mexico that becomes your center of life). It ends when:

• You abandon your permanent Mexican home AND
• Your center of vital interests moves elsewhere.

Critically: Mexican law presumes you remain Mexican-resident for 5 years after departure if you move to a jurisdiction Mexico classifies as a “preferential tax regime” (REFIPRE — Mexico’s blacklist of low-tax jurisdictions, includes UAE, several Caribbean countries, parts of the Channel Islands, etc.). To defeat the presumption, you must prove genuine residence elsewhere.

The clean exit requires:

1. Cancel your RFC residence with SAT (notify of departure).
2. Terminate your Mexican lease or sell your home.
3. Move family, if applicable.
4. File a final return as Mexican-resident for the partial departure year (or fully if departure is mid-year).
5. Obtain tax residency certificate from your new country.

Special considerations for US citizens

US citizens are notable in the Mexican context because:

• The US-Mexico tax treaty is broadly favourable.
• US citizens remain US-taxed regardless of Mexican residence (citizenship-based taxation).
• Mexican tax paid generates US foreign tax credits, often reducing US liability significantly.
• For most US-citizen retirees in Mexico, properly-coordinated planning leaves them paying primarily Mexican rates (when resident) with US credits reducing US tax.

The most common Mexico residency mistakes

1. Assuming the visa = tax residency. A Temporary or Permanent Resident card is necessary for legal presence, but not by itself the trigger.
2. Renting year-round while claiming to be a tourist. A year-round Mexican lease creates a “permanent home,” even if you spend only 6 months physically there.
3. The 50%-of-income test. If a significant portion of your income comes from Mexican sources (consulting for Mexican clients, Mexican rental income), you can hit the center-of-vital-interests test even with moderate physical presence.
4. Forgetting the 5-year REFIPRE presumption. Moving from Mexico to UAE or the Caribbean without solid new-country residence documentation can leave you presumptively Mexican-resident.
5. Not properly canceling RFC residence. Just leaving Mexico doesn’t update SAT’s records.
6. Mixing immigration and tax timelines. Visa renewal years and tax years are independent.

Practical patterns

Pattern A: Snowbird (winter-only). 4 months in Mexico, short-term Airbnb, no Mexican home maintained, all income foreign. Mexican non-resident. Tourist FMM may be granted at officer’s discretion (now often less than 180 days).

Pattern B: Full retiree. Year-round in Mexico, Permanent Resident visa, owned home. Mexican tax resident. Worldwide income taxed; US-Mexico treaty and foreign tax credits reduce double-tax exposure for US retirees.

Pattern C: Cross-border worker. Mexican client base, frequent Mexico travel, US residence. Likely Mexican non-resident but careful documentation needed if Mexican-source income approaches 50% of total.

Pattern D: Digital nomad on Temporary Resident visa. 7-8 months in Mexico, foreign-only income, Mexican apartment rented year-round. High residency risk — the Mexican apartment + extended time + Temporary Resident card collectively look like residence.

Mexican residency hinges on permanent-home and center-of-life tests, not just days. But day counts feed every supporting argument when SAT asks. DaysAbroad keeps that evidence base intact.
