Working remotely from Mexico: how to get your tax and visa status right

Every year tens of thousands of foreigners move to Mexico: digital nomads drawn by the cost of living and the weather, executives relocated by their employers, retirees, European and Latin American entrepreneurs. Quality of life is excellent. The tax system, however, is a minefield for anyone who does not know its rules.

The most common mistake

The most frequent — and most expensive — mistake is assuming that "because I'm paid from abroad, I owe nothing in Mexico". Mexico taxes on the basis of tax residency, not on where the money comes from. If you are a Mexican tax resident, your worldwide income is in scope, including the salary or fees paid into your home-country account.

When are you a Mexican tax resident?

Article 9 of the Federal Tax Code sets the test, and it does not start with 183 days:

1. You are a resident if you have established your home (casa habitación) in Mexico. A place you actually live in, owned or rented.
2. If you also have a home in another country, you are a Mexican resident when your centre of vital interests is in Mexico — meaning either:
   • more than 50% of your annual income comes from Mexican sources, or
   • Mexico is the main centre of your professional activities.

For a remote worker with foreign clients who keeps a home elsewhere, the first income test is usually not met. The second test — where you actually work from — is where the argument happens, and it gets harder to win the longer Mexico is where you live and work. We explain the mechanics in detail in our tax residency guide.

Immigration status: which one you need

1. Visitor (FMM)

Up to 180 days, at the officer's discretion. It does not allow you to work for Mexican employers or be paid for activities in Mexico. Occasional remote work for a foreign employer is generally tolerated, but if you are living here habitually, it is the wrong status.

2. Temporary residency

One to four years, renewable. The standard status for digital nomads, relocated executives and retirees. It gives you a CURP, lets you get an RFC and open bank accounts, and can be extended to include work authorisation.

For remote workers it is usually obtained by economic solvency: steady monthly income over the last six months, or average savings over the last twelve, above thresholds each consulate sets from the Mexican minimum wage. Those figures change every January and differ between consulates, so check the one with jurisdiction over you. The application starts at a Mexican consulate abroad, and on arrival you have 30 days to exchange the visa for your card at the INM. Our residency service covers the process.

3. Permanent residency

Indefinite. Usually reached after four years of temporary residency, through family ties to Mexicans, or directly for retirees with sufficient pension income.

Getting an RFC as a foreigner

Once you have a CURP, which comes with temporary residency, you register with the SAT: book an appointment, bring your resident card, CURP and proof of Mexican address no older than three months, and the RFC is issued the same day. The full process, and why the appointment is the hard part, is in our RFC guide.

Which tax regime applies

A. Paid from abroad for services performed from Mexico

The typical digital nomad. If you are a tax resident, you declare in Mexico. The regime is usually the general business and professional activities regime, or RESICO for individuals if you qualify (see our RESICO guide).

B. Employed and paid locally in Mexico

Your employer withholds income tax and pays it to the SAT under the salaries regime. If you also have foreign income, you declare it in your annual return.

C. Passive income from abroad (rent, dividends, interest)

Declared in your Mexican annual return. If tax was paid in the source country, the relevant treaty lets you credit it against Mexican income tax, up to the Mexican tax on that income.

Double taxation treaties

Mexico has treaties with dozens of countries, including the United States, Canada, the United Kingdom, Spain, Germany, France, Italy, the Netherlands and most of Latin America. In broad terms:

1. You declare the income where the rules require it — country of residence and, where applicable, country of source.
2. The source country may tax first, sometimes only up to a capped rate.
3. Your country of residence credits what was paid in the other country.
4. You pay the difference, if any.

Applying treaties correctly is technical. Get it wrong and you can pay twice, or have the credit rejected.

A typical case: an American remote worker in Mexico City

Sarah, 32, UX designer. Works remotely for a San Francisco start-up. Moved to Mexico City in January on a visitor permit, leaving for Guatemala every six months to re-enter. Rents an apartment here, no longer has a home in the US, keeps filing with the IRS and assumed that was enough.

What is missing:

• Mexican tax residency: very likely. Her only home is here and she works from here.
• Immigration: irregular in substance. She lives here on a status meant for visits.
• United States: she remains taxable as a US citizen wherever she lives.

The fix:

1. Apply for temporary residency at a Mexican consulate.
2. Get a CURP and RFC on return.
3. Register under the professional activities regime or RESICO, depending on her exact income.
4. File monthly with the SAT on the income paid from abroad.
5. In the Mexican annual return, apply the US–Mexico treaty.
6. On her US Form 1040, use the Foreign Earned Income Exclusion or the Foreign Tax Credit — the exclusion ceiling is updated every year, so her preparer should use the current figure.

Structured properly, Sarah may end up paying less total tax than filing only in the US, before even counting the lower cost of living.

Mistakes that can cost you your status

• Working locally on a visitor permit. Serving Mexican clients without the right status can lead to cancellation and a ban on re-entry.
• Not filing with the SAT while a tax resident. Tax compliance can come up at residency renewal, and omissions complicate it.
• Getting paid in crypto or cash with no trail. Anti-money-laundering rules require documenting the origin of funds, and undocumented income can undermine the solvency you need to renew.

Bottom line: set it up at the start

Living in Mexico as a foreigner is a great decision. But the first months are critical for your immigration and tax position to be structured properly. What is done wrong at the start costs many times more to fix later, once penalties, surcharges and legal costs are added. The SAT can review up to five years back.
