Leaving Mexico

Leaving physically may not end residence

Federal Tax Code article 9 contains specific rules for people and entities ceasing Mexican tax residence. Failing to provide the required notice or evidence of the new tax residence can preserve Mexican residence. This is different from a tax on a deemed asset sale.

The current code also addresses moves into preferential-tax regimes. Subject to its exceptions, residence can continue for the departure fiscal year and five following fiscal years. This needs destination-specific analysis, not a generic statement that Mexico has no departure issue.

The information-exchange exception is specific

The code describes an exception involving a broad tax-information-exchange agreement and an international instrument enabling administrative assistance in notification, collection and recovery. Do not assume that any treaty, a residence permit or a general reputation for cooperation satisfies those conditions.

Evidence of actual new tax residence must also be considered. An investment visa without the required tax-residence facts may not solve the Mexican side of the move.

Plan the filing sequence

Article 9 requires a notice in advance of the residence change, using the period specified in the code. The practical process, required forms and supporting documents should be confirmed before the proposed date.

Coordinate home and family arrangements, the new-country residence basis, expected income, asset disposals and any changes in company management. If there is a dual-residence period, analyse treaty rules and the available evidence rather than assume the later permit controls.

Corporate departure can trigger a deemed liquidation

Income Tax Law article 12 treats a Mexican-resident legal entity as liquidated when it ceases residence under the code or an applicable treaty. Its Mexican and foreign assets are treated as disposed of at market value. Moving the owner and migrating the company therefore need separate calculations.

Business owners have an additional workstream

• Will any company’s principal administration or effective management remain in Mexico?
• Will local employees, agents or operations continue?
• Are corporate migration, transfer, liquidation or withholding rules relevant?
• Which foreign entities and information reports remain within scope?
• Who will receive authority notices and maintain records after departure?

Document the transition

Retain the notice, new-residence evidence, relevant contracts, management records and final or continuing returns. Update banks and service providers accurately. We can help coordinate the departure and arrival as one project and review whether the business structure still matches the new operating reality.

Use the fifteen-day notice rule as a planning constraint

The current code describes the notice as due within the fifteen days immediately preceding the residence change. A destination visa approval several months earlier is not that notice, and updating a bank’s address does not replace it. Confirm the current SAT filing mechanics and required proof before entering that period.

Build a timeline for the new home, professional activities and qualifying new tax residence. Where the destination grants a permit with minimal presence, investigate what additional facts establish tax residence there. The evidence should support the real change and the representations in the Mexican filing.

A low-tax move can create several years of overlap

The continued-residence rule for a move into a preferential regime covers the fiscal year of the notice and the five following fiscal years. The code describes an exception requiring both broad tax-information exchange and an international instrument allowing administrative assistance with notification, collection and recovery.

Test the specific destination and legal instruments rather than infer the answer from its general treaty count. If the rule applies, model the retained Mexican tax obligations alongside the destination’s rules. The question is continued residence and taxation, not merely whether the individual faces a one-time departure charge.

Keep the company migration decision separate

Article 12 treats a legal entity as liquidated when it stops being Mexican-resident under the code or a treaty, and applies market values to assets in Mexico and abroad. An entity that owns valuable goodwill, intellectual property or investments can therefore need valuations and a substantial migration calculation.

The founder may be able to move while leaving a genuinely Mexican company resident and compliant, or may establish separate foreign operations without migrating it. The choice depends on commercial authority, employees, contracts and tax consequences. Document the selected arrangement and continuing Mexican filings rather than assume every component must leave together.
