Moving to Mexico from the US

Mexico hosts the largest community of US citizens living outside the United States, and the reasons are structural rather than sentimental: a shared land border, direct flights from almost every US hub, and a residency system that lets a foreigner qualify on passive income alone, with no job offer, no language test and no investment requirement.

About 131.9 million people live in Mexico. The country you actually move to depends heavily on where you land. Mexico City and Monterrey are large, expensive by Mexican standards, and full of formal-sector work. Guadalajara, Queretaro and Puebla are the middle ground, with good hospitals and lower rents. Merida, San Miguel de Allende, Puerto Vallarta, Lake Chapala and parts of Baja hold established American and Canadian communities where English will carry you further than it should.

The headline finance number: OECD's comparative price levels put Mexican household consumer prices including rent at 62 against the United States at 100 in July 2026, so roughly 38% below. That gap has narrowed. The peso averaged 19.24 to the dollar across 2025 and sat at 16.956 on 3 September 2026 on the Banxico FIX rate, so a fixed dollar income now buys about 12% fewer pesos than it did on the 2025 average. Mexico is still substantially cheaper than the United States, but anyone budgeting from 2023 numbers will be short.

Anchor everything to the exchange rate, because that is the variable that actually moves. A metropolitan one-bedroom runs roughly USD 765 a month in a city centre and USD 495 further out, but treat both figures as indicative: no Mexican statistical agency publishes advertised rents by dwelling size, so those two dollar amounts are the rent index of 45 applied to an assumed US metropolitan one-bedroom, not a survey result. The checkable number behind them is the price level, not the listing.

The official comparison is less flattering than the crowd-sourced ones. OECD's comparative price levels put Mexican household consumption including rent at 62 against the United States at 100 in July 2026, so about 38% below, not the near-half you will read elsewhere. Rebasing OECD's 2024 price level indices onto that same July 2026 footing, using Mexican and US category inflation and the current peso, gives groceries at 93, restaurants at 73, transport at 84 and housing rentals at 45. At the 3 September rate each of those is about 3% higher again.

Food is the surprise, and it is the number most likely to break your budget. Measured on a like-for-like basket, Mexican grocery prices are within a tenth of US ones, and both OECD in 2024 and the World Bank's 2021 ICP round say the same thing. What is genuinely cheap in Mexico is anything with a large domestic labour or land component: rent, restaurant meals, haircuts, domestic help, dentistry. Not the contents of a shopping trolley.

Utilities are the standout saving, and the reason is consumption rather than price. Electricity, LP gas, water and refuse for a normal dwelling on CFE's subsidised domestic tariff come to an estimated USD 57 a month against about USD 210 for the same basket in the United States, because Mexican homes have no central heating, smaller floor areas and a fraction of US household electricity use. That USD 57 is an estimate rather than a measured statistic, so budget a margin. Be careful in hot coastal cities: CFE's residential subsidy disappears once consumption crosses a threshold, and the resulting DAC tariff can multiply a summer bill several times over.

Transport does not follow the pattern at all. Regular gasoline averaged MXN 23.67 a litre across the 13,794 Mexican service stations posting a regular price on 4 September 2026, about USD 5.28 a US gallon against the EIA national average of USD 4.07, and vehicles are traded goods priced close to US levels. If you drive a lot, Mexico is the more expensive country.

Americans do not need a visa to visit. You get a passport stamp at the border for up to 180 days, but the number of days is at the officer's discretion and 30 to 90 days is now routine, particularly for people who have already spent long stretches in Mexico. The permit cannot be extended from inside the country, and living permanently on tourist stamps is the single most common way Americans get into trouble at the border.

The real route is the Temporary Resident Visa, applied for in person at a Mexican consulate in the United States and never from inside Mexico. You qualify on money alone. The 2026 thresholds are multiples of the UMA, currently MXN 117.31 a day: 680 UMA of monthly net income over the past six months, MXN 79,771 or roughly USD 4,300 to USD 4,700, or an average monthly balance of 11,460 UMA over twelve months, MXN 1,344,373 or roughly USD 73,000 to USD 79,000. Each dependent adds 220 UMA, about MXN 25,808. Because each consulate applies its own exchange rate, the dollar figure genuinely differs between San Francisco and Houston.

Temporary residency runs one year and renews inside Mexico to four years total, after which you can apply for permanent residence with no test. Property ownership, investment in a Mexican company, scientific research and family ties are separate qualifying categories listed by the SRE. Budget for the INM card fees, which changed on 1 January 2026.

Two tax systems will look at you, and they use different tests.

The United States taxes citizens on worldwide income wherever they live, so you keep filing a 1040. For 2026 the Foreign Earned Income Exclusion is USD 132,900 per qualifying person, but it covers earned income only, not pensions, Social Security, dividends or capital gains. Many Americans in Mexico do better with the Foreign Tax Credit once Mexican tax has actually been paid, because Mexican rates on middle incomes are not trivial. Add an FBAR if your foreign accounts together exceed USD 10,000 at any point in the year, and Form 8938 above higher thresholds.

Mexico does not use a 183-day test. Under Article 9 of the Codigo Fiscal de la Federacion you become a Mexican tax resident once you establish a casa habitacion, a permanent home, in Mexico. If you also keep a home in the US, the tiebreaker is your centre of vital interests: Mexico wins if more than half your calendar-year income comes from Mexican sources, or if Mexico is the principal place of your professional activity. Immigration status and tax residency are separate questions.

Resident rates run from 1.92% to 35%, with the top bracket starting above MXN 5,107,703.93 of annual taxable income. IVA is 16%, reduced to an effective 8% in designated northern border municipalities. The 1992 treaty and its 2003 protocol are in force. There is no totalization agreement, so self-employed Americans owe the full 15.3% US self-employment tax regardless.

Verify the Mexican half with SAT, the Servicio de Administracion Tributaria, and not with the IRS. The legal basis is Article 9 of the Codigo Fiscal de la Federacion, and SAT's portal carries the current rules, the RFC procedures and the forms; the IRS can tell you what the treaty says but has no authority over whether Mexico considers you resident.

Mexico runs three parallel systems. IMSS covers private-sector employees, ISSSTE covers federal workers, and IMSS-Bienestar covers people without social security. The OECD puts core-service coverage at 78% of the population, health spending at USD 1,588 per person in PPP terms against an OECD average of USD 5,967, and 2.7 practising physicians per 1,000 people against an OECD average of 3.9. Out-of-pocket payments make up 41% of all health spending in Mexico against 11% in the US, the highest share in the OECD. That single number tells you how the system really works: people pay cash.

Legal residents can buy into IMSS voluntarily through the Seguro de Salud para la Familia, known as Modalidad 33. It is one annual premium priced by age, and for 2026 it runs MXN 12,350 at ages 30 to 39, MXN 14,850 at 50 to 59 and MXN 20,600 at 60 to 69, so roughly USD 730 to USD 1,215 a year. IMSS screens for pre-existing conditions and applies waiting periods before some treatments, so confirm the current rules before you count on it for a condition you already have.

Most Americans instead buy a Mexican major-medical policy and pay cash for routine visits. Premiums are not published centrally; brokers commonly quote something in the range of USD 100 to USD 200 a month for a healthy person in their forties or fifties, and considerably more past 60. Medicare pays nothing in Mexico.

Get a CURP, the national identity number, as soon as your residence card is issued. Very little works without it: bank accounts, phone contracts, IMSS registration, utility accounts. If you will earn or invoice inside Mexico you also need an RFC from SAT.

Banking is the standard friction point. Mexican banks want your residence card and proof of address, and US banks increasingly close accounts held by customers with a foreign mailing address, so keep a US address and settle your brokerage relationships before you leave. Multi-currency transfer services generally beat wire fees on peso conversions.

Bringing a car is a decision, not a formality. Foreign-plated vehicles need a Temporary Import Permit from Banjercito to travel beyond the border zone, and permanent residents cannot hold one at all, so people who go permanent usually sell the US car and buy locally, where prices sit close to US levels.

Where you live matters more in Mexico than in most countries. The State Department issues advisories state by state rather than nationally, and the gap between the safest and least safe Mexican states is enormous. Read the advisory for the specific state you are considering, not the country.

Finally, learn Spanish. Merida, San Miguel and Chapala will let you get by without it, but bank disputes, immigration renewals, medical appointments and landlord problems all happen in Spanish, and the residency system offers no language accommodation.
