# Residence and cross-border personal income

Mexican tax residence is based principally on home and vital interests, with special nationality-related presumptions. Residents face worldwide income taxation; nonresidents generally face Mexican-source or establishment-attributable taxation.

Scope: Federal personal income-tax residence and cross-border scope, without tax-rate, special-regime or individual treaty calculations.

Jurisdiction: Mexico — federal income tax. Sources reviewed 2026-09-22; review due 2026-12-21.

General information, not personal tax advice. Nationality, tax residence and source of income are different questions. Consult the tax authority or a qualified adviser for your circumstances.

## Home and vital interests

A home in Mexico establishes residence. With homes in Mexico and another country, the centre of vital interests controls; examples include more than half of annual income coming from Mexican sources or the principal professional-activity centre being in Mexico.

Evidence: conditional. [Cámara de Diputados: Federal Fiscal Code — last amendment 9 April 2026](https://www.diputados.gob.mx/LeyesBiblio/pdf/CFF.pdf). Source location: Federal Fiscal Code Article 9(I)(a) (printed p.5)..

## Nationality is not the whole test

Mexican nationality creates a rebuttable residence presumption. Mexican-national state officials and workers remain resident even with vital interests abroad; this is not a universal citizenship-based tax rule.

Evidence: conditional. [Cámara de Diputados: Federal Fiscal Code — last amendment 9 April 2026](https://www.diputados.gob.mx/LeyesBiblio/pdf/CFF.pdf). Source location: Federal Fiscal Code Article 9(I)(b) and following paragraph (printed p.5)..

## Worldwide versus source-based taxation

Residents are taxable on income regardless of source. Nonresidents are taxable on income attributable to a Mexican permanent establishment and on Mexican-source income without such an establishment or not attributable to it.

Evidence: documented. [Cámara de Diputados: Income Tax Law — last amendment 1 April 2024](https://www.diputados.gob.mx/LeyesBiblio/pdf/LISR.pdf). Source location: Income Tax Law Article 1(I)–(III) (printed p.1)..

## Residence does not end just by leaving

Failure to prove new foreign tax residence, or moving to a preferential regime, can retain Mexican residence for the notice year and five following fiscal years. The foreign-residence exception requires both broad information exchange and the specified mutual-assistance treaty. Departure notice is required within the 15 days immediately before the change; omitting it retains residence.

Evidence: conditional. [Cámara de Diputados: Federal Fiscal Code — last amendment 9 April 2026](https://www.diputados.gob.mx/LeyesBiblio/pdf/CFF.pdf). Source location: Federal Fiscal Code Article 9, final three paragraphs (printed pp.5–6)..

## Treaties and foreign-tax credits

Treaty benefits require residence evidence and satisfaction of treaty and procedural conditions. Foreign income tax on income also taxable in Mexico may be credited subject to statutory limits, including country-by-country limits for individuals and supporting payment evidence; the full foreign bill is not automatically creditable.

Evidence: conditional. [Cámara de Diputados: Income Tax Law — last amendment 1 April 2024](https://www.diputados.gob.mx/LeyesBiblio/pdf/LISR.pdf). Source location: Income Tax Law Article 4 and Article 5, opening paragraph, individual-credit limits and payment-evidence paragraphs (printed pp.4, 6, 9–10)..

## Scope and limitations

- Immigration status or a passport alone does not resolve tax residence; Article 9 is not a general 183-day test.
- This is an income-tax scope summary, not a total tax-burden or social-security calculation.
- Treaty residence, income classification, credit restrictions and departure evidence require case-specific review.
