Retiring in Mexico: residency, Social Security and taxes

Getting the immigration part right

Mexico has no visa called a retirement visa. What retirees use is temporary residency by economic solvency: you demonstrate pension income or savings sufficient to support yourself without working in the Mexican job market. The amount is calculated on a government reference unit and each consulate publishes its own figure, so the number you read in a Facebook group is probably from a different consulate and a different year.

Two things trip retirees up specifically:

• You start at a consulate abroad, not from inside Mexico. Coming down as a tourist to "look around and sort it later" usually means flying back to the US to apply.
• The 30-day exchange. The visa stamped in your passport only gets you in. Once you land you have 30 calendar days to exchange it at the immigration institute for the actual resident card. Missing that window collapses the whole process.

After four years of temporary residency you can apply for permanent residency, which does not expire and does not need renewing. Some consulates grant permanent status directly to older applicants with sufficient income — worth asking about, because it saves four years of renewals. The full detail is in our residency guide.

The tax question that actually decides the budget

Social Security

Under article 19 of the US–Mexico income tax treaty, Social Security benefits paid by one country to a resident of the other, or to a citizen of the paying country, are taxable only in the paying country. In plain terms: Mexico does not tax your US Social Security, even if you are a Mexican tax resident. It remains taxable in the US under the usual rules, where up to 85% of the benefit can be included depending on your combined income.

That one provision is a bigger part of Mexico's appeal to American retirees than most people realise, and it is why a retiree living mainly on Social Security often owes nothing at all in Mexico.

Private pensions, IRAs and 401(k)s

Here we are going to be honest rather than confident: this is a contested area. The treaty addresses pensions, the saving clause preserves US taxing rights over US citizens, and US domestic rules on distributions from retirement accounts interact with both. Different well-qualified advisers reach different conclusions on the same facts, and the right treatment depends on the type of payment and its source.

What we can tell you is what not to do: do not assume that because Social Security is protected, everything else is. And do not let your Mexican adviser and your US preparer work from different assumptions, which is where the real damage happens.

Are you even a Mexican tax resident?

Retirees often assume they automatically become one on arrival. Mexican domestic law is about where your home and your centre of vital interests are, not a day count — the mechanics are in our tax residency guide. If you are a Mexican tax resident, your worldwide income is in scope in Mexico and you file an annual return by 30 April, even where the treaty means little or nothing is actually payable here.

Healthcare, planned properly

Medicare does not follow you. Outside a handful of narrow exceptions it does not pay for care received abroad. Many retirees keep Part B active for trips back to the US and build a separate plan for Mexico.

Your options here are, roughly:

• IMSS voluntary enrolment. Residents can join the social security institute for an annual premium that is remarkably low by US standards. The catches are waiting periods and exclusions for pre-existing conditions, so it works as a backstop, not as a like-for-like replacement.
• Private Mexican insurance. Considerably cheaper than US equivalents, with the usual underwriting on pre-existing conditions and, typically, an upper age limit for new policies. Get in earlier rather than later.
• Paying privately. A great deal of routine and specialist care in Mexico costs a fraction of US prices, and plenty of retirees simply budget for it and insure only against catastrophic events.

The paperwork that makes daily life work

• CURP and RFC. Even with no Mexican income, you will be asked for them constantly — banks, insurers, landlords, utilities. See the RFC guide.
• A Mexican bank account. Much easier with a resident card, and it removes years of foreign transaction fees.
• A Mexican will for assets located here. It does not replace your US estate plan; it sits alongside it and spares your heirs a cross-border probate they will not enjoy.
• Property held sensibly. If you are buying, read the property guide first — particularly if one of your parents was Mexican, because that changes the structure entirely.
