Does Mexico tax U.S. retirement income? It depends on whether you become a Mexican tax resident. If you keep your main home in the U.S. and spend winters in Los Cabos, Mexico generally doesn’t tax your U.S. retirement income. If Mexico becomes your home, you’re taxed on worldwide income, with two big protections: under the U.S.–Mexico tax treaty, U.S. Social Security is taxable only in the U.S., and any Mexican tax on pensions or IRA withdrawals can be credited against your U.S. tax. Either way, U.S. citizens still file a U.S. return. This guide is for retirees from California, Texas and Arizona.

| U.S. only Where Social Security is taxed (treaty) |
Home What decides Mexican tax residency |
| Always U.S. citizens file a U.S. return |
Credit Mexican tax offsets U.S. tax on the same income |
Mexico doesn’t use a simple day count. Under the Federal Tax Code, you’re a tax resident if you establish your home in Mexico. If you have a home in both countries, Mexico looks at your center of vital interests: where most of your income comes from or where your main activities are.
Your immigration status doesn’t decide it by itself. A temporary or permanent resident card is not the same as tax residency, although living in Mexico full time usually makes you a tax resident.
| Your Situation | Likely Mexican Tax Status |
|---|---|
| Main home in the U.S., winters in Los Cabos | Not a Mexican tax resident |
| Sold your U.S. home and live in Los Cabos full time | Mexican tax resident |
| Homes in both countries | Depends on your center of vital interests; get advice |
| Income | Not a Mexican Tax Resident | Mexican Tax Resident |
|---|---|---|
| U.S. Social Security | U.S. only | U.S. only (treaty, Article 19) |
| Private pension, 401(k), IRA | U.S. only | Mexico can tax it; the U.S. also taxes it, with a foreign tax credit to avoid paying twice |
| Rent from your Cabo home | Taxed in Mexico | Taxed in Mexico |
| Sale of your Cabo home | Taxed in Mexico | Taxed in Mexico, with possible exemption for your residence |
U.S. citizens report all of this on their U.S. return too; the foreign tax credit prevents double taxation. For selling, see Do I Pay Taxes in the US if I Sell My House in Mexico?

No. Under Article 19 of the U.S.–Mexico tax treaty, U.S. Social Security is taxable only in the United States, even if you’re a Mexican tax resident.
Only if you’re a Mexican tax resident. Then Mexico can tax them, and you can use a foreign tax credit on your U.S. return.
Not by itself. Mexico decides based on where you have your home and, if you have homes in both countries, your center of vital interests.
Yes. U.S. citizens file a U.S. return on their worldwide income no matter where they live.
Not automatically. Immigration status and tax residency are separate, but living in Mexico full time usually makes you a tax resident.
