Am I a tax resident of Mexico?

Mexico does not use a simple day count — residency turns on where your home and economic life actually are. Here is the test, and what it means once it applies.

The residency test in Mexico

Mexico does not test residency by a fixed day count. Instead the test looks at where your permanent home, family, and economic interests actually sit — a facts-and-circumstances test rather than a number to count against.

Residency home test
Primary Mexican individual tax-residency test: having a home in Mexico makes a person resident. Only if the individual also maintains a home in another country does the analysis move to the centre-of-vital-interests test (see residency_center_of_vital_interests_test). Mexico's test is not a standalone day-count rule.

Residency deregistration notice requirement
Relevant for remote workers/expats leaving Mexico: residency does not lapse automatically on departure. Without filing the deregistration notice with the tax authority, an individual who otherwise meets the departure conditions remains a Mexican tax resident on paper. [source]PwC Tax Summaries“When individuals (or corporations) omit to submit such notice, they will not lose their status as Mexican residents.”View source · accessed 2026-08-20
Residency tax haven relocation rule
Anti-avoidance rule aimed at citizens (not all residents) who move to low-tax jurisdictions: residency is deemed to continue for the year the deregistration notice is filed plus the following five years, unless an information-sharing treaty with that jurisdiction is in effect. [source]PwC Tax Summaries“A Mexican citizen who moves to a country that is considered a tax haven by Mexico will remain a tax resident of Mexico for the year in which the change of tax residency suspension notice is filed and the following five years”View source · accessed 2026-08-20
Residency center of vital interests test
Alternative (either/or) test applied when a home exists both in Mexico and abroad. Mexico is treated as the centre of vital interests if either more than 50% of the person's income is Mexican-sourced in a calendar year, or Mexico is the primary place of the person's professional activities. This is the closest Mexico has to a quantitative residency threshold; there is no separate physical-presence/day-count rule in the general test.

If your situation is borderline

With no day count to fall back on, Mexico weighs facts a calendar can’t: where your home actually is, where your family lives, and where your economic life is centred. Two people with identical travel patterns can land on opposite sides of this test depending on those ties — a day-counter would not help either of them.

What residency actually changes

Once you are tax resident, Mexico generally taxes your worldwide income, topping out at 35%PwC Tax Summaries“35.00”View source · accessed 2026-08-20. Mexico's personal income tax is progressive with 11 marginal brackets (1.92% to 35%), not flat. The top rate of 35% applies to taxable income above MXN 5,107,703.93 for calendar year 2026 (see pit_income_brackets for the full scale). Stay a non-resident, and Mexico typically taxes only income sourced there.

When to talk to an advisor

This page maps Mexico’s general residency test. It cannot weigh your treaty position, your specific ties, or the timing of a move. If meaningful money depends on the answer, have a qualified advisor in Mexico (and in your home country) review your situation before you act.
