What this means if you relocate to Mexico
The first thing that matters is tax residency: permanent home / centre of vital interests (over 50% income or main professional base in Mexico). Because Mexico has no simple day count, residency turns on where your real home and life are, which is harder to plan around than a day rule.
Once resident, Mexico taxes your worldwide income, so income earned abroad is in scope unless a treaty or special regime says otherwise. The top 35% rate only bites at the highest income band — an average earner pays less.
Foreign pensions and investments
Foreign pension: Taxable as income in the annual return (treaty/FTC relief may apply). Foreign capital gains and dividends: Worldwide capital gains taxable; foreign dividends taxable with an additional 10% tax on dividends. These outcomes can be overridden by a double-tax treaty, which decides whether the source country or Mexico taxes each stream — a key reason retirees should map their specific income against the relevant treaty.
US citizens and social security in Mexico
| Question | Mexico |
|---|---|
| US income tax treaty? | Yes |
| US social-security totalization agreement? | No |
| Tax basis for residents | Worldwide |
| Top personal income tax | 35% |
A US tax treaty with Mexico helps reassign taxing rights and reduce withholding, and US citizens lean on the Foreign Earned Income Exclusion and Foreign Tax Credit to avoid double income tax. With no totalization agreement, you can be exposed to social-security-type charges in both the US and Mexico. See our guides on FEIE vs the Foreign Tax Credit and totalization agreements.

Frequently asked questions
When do you become a tax resident of Mexico?
Permanent home / centre of vital interests (over 50% income or main professional base in Mexico). There is no simple day count — residency turns on facts and circumstances such as your home and centre of life. Once resident, Mexico taxes you on your worldwide income. This is general information for 2026, not tax advice — verify with the official authority.
How does Mexico tax a foreign pension?
Taxable as income in the annual return (treaty/FTC relief may apply). Tax treaties can reassign who taxes a pension, so the outcome depends on your nationality and the source country. Confirm with a cross-border adviser before relying on this.
Does Mexico have a special expat tax regime?
No. Mexico has no dedicated expat, non-dom or retiree income-tax regime in our dataset — a mover is taxed under the ordinary rules (worldwide basis, top rate 35%).
Is Mexico good for US citizens or retirees?
Mexico has a US income tax treaty and does not have a US social-security totalization agreement. Without a totalization agreement, you can owe social-security-type contributions in both the US and here. US citizens are taxed on worldwide income wherever they live, but the Foreign Earned Income Exclusion and Foreign Tax Credit usually prevent double income tax. Not tax advice.
