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.
