Most relocation guides to Mexico stop at the question of which visa you need. The really important question comes afterwards: when do you become tax resident in Mexico, and is that even what you want? This distinction can easily mean a five-figure difference in tax each year, depending on how your income sources are structured. I am a realist, not a salesman, and this distinction between residence permit and tax residence is exactly where most one-size-fits-all relocation guides stop, even though it is the most important point in the whole process for your actual tax bill.
The residence permit in detail
For tourist stays of up to 180 days, if you hold a passport from the EU, the UK, the US, Canada or most other Western countries, you do not need a visa, only a passport with at least six months' remaining validity and the digital entry card FMM (Forma Migratoria Múltiple). Since 2022 it has gradually gone paperless and works fully digitally as a QR code at major airports such as Cancún, Mexico City, Guadalajara, Monterrey and Mérida. If you enter by land or sea, you still have to apply for the FMM online in advance. The length of stay is set at the border by the immigration officer at their discretion, between 30 and 180 days. There is no legal right to the full six months, although in practice this rarely becomes a problem.
For a longer stay there are two stages. Since a resolution of 25 July 2025, the Residente Temporal requires either net income of 680 UMA days per month, roughly EUR 3,550, over the last six months, or an average account balance of about EUR 60,000 over twelve months. The switch from the old link to the minimum wage to the UMA is more than a formality: the Mexican minimum wage rose by around 200% between 2018 and 2026, the UMA by only just under a third in the same period, which gives future applicants far more predictable and lower thresholds than a few years ago. After arriving on the visa, you have 30 calendar days to apply at the INM for the physical Tarjeta de Residente Temporal with biometric data. After four years you can switch to the indefinite Residente Permanente without proving your means again; the fee for this is around MXN 13,579. Retirees with income funded from abroad of around 500 UMA days, roughly EUR 2,610 a month, can skip the temporary stage and apply directly for permanent residence.
For employees: if you have a job offer with salary paid from Mexico, you do not need your own proof of means, because the future employer files the application directly with the national migration institute, the INM. Remote work for a foreign employer with salary paid into a foreign account is expressly allowed under the Residente Temporal, without a separate Mexican work permit, a point many digital nomads discover, with relief, only late in the process.
The consulate appointment and documents: what is really required
The application for Residente Temporal or Permanente goes through the Mexican consulate in your country of residence, not through an authority in Mexico itself. You need a valid passport, full proof of means for the last six or twelve months as bank statements or an income certificate, a recent passport photo and the completed application form, and at most consulates now an appointment booked online in advance through the relevant portal. Once you have attended the appointment, the visa itself is usually processed within a few working days. The visa issued is then valid for 180 days and allows a single entry into Mexico. Travel health insurance for the transition period until you have your own Mexican cover is not formally a requirement in every case, but in practice it is strongly recommended, because the Mexican public health system is not a practical first port of call for newly arrived foreigners without a social security number.
The decisive difference: a residence permit is not tax residence
This is where planning separates the wheat from the chaff. A Mexican residence permit does not automatically make you tax resident in Mexico, and conversely you can become tax resident without a formal residence permit. Unlike many other countries, Mexico has no 183-day rule. Tax residence is triggered instead as soon as you maintain a home in Mexico. If you also have a home abroad at the same time, the centre of vital interests decides: it lies in Mexico only if more than 50% of your total income comes from Mexican sources, or if Mexico is the main place of your professional activity, as the PwC summary of Mexican residence rules sets out.
This opens up legal room for planning that is simply missing from many relocation guides. If you earn no Mexican-source income and can show that your centre of life remains abroad, for example through a second home you genuinely use and economic activity carried on mainly there, you can legally keep your foreign income outside Mexican taxation, even with a valid Residente Temporal or Permanente in your pocket. A mere letterbox or a formally registered second home without real substance is not enough: the Mexican authorities and, if in doubt, the tax authority in your home country look at your actual living circumstances, not at paperwork.
Checklist: how to steer Mexican tax residence deliberately
If you want a Mexican residence permit without automatically becoming tax resident there, it pays to document deliberately from the start. That means a home outside Mexico that you genuinely use and can prove, no Mexican-source income or at least a share well below 50% of your total income, professional activity carried on mainly outside Mexico, and bank statements, leases, utility bills and travel records that prove your actual centre of life, should the SAT or another tax authority ever ask. If, on the other hand, you deliberately want to become a Mexican tax resident, for example because RESICO is more attractive for your business than taxation in your home country, you should do exactly the opposite and document your Mexican home, your Mexican income and your place of management clearly and verifiably. Both routes are legal, but both require real substance rather than mere paperwork, and both should be planned with your overall situation in mind, not for Mexico in isolation.
RESICO: the most interesting regime for the self-employed and small businesses
If, on the other hand, you actually earn Mexican income, for example from local clients, rentals or a small business based in Mexico, you should take a close look at the Régimen Simplificado de Confianza, RESICO for short. With annual turnover of up to MXN 3.5 million, roughly EUR 165,000, you pay effectively only between 1% and 2.5% income tax on the amounts received, instead of slipping into the regular progressive income tax scale with eleven brackets from 1.92% to 35%. For tax residents with Mexican business income below the turnover cap, RESICO is one of the cheapest regimes for entrepreneurs anywhere in the world, combined with the fact that Mexico has no wealth tax and no inheritance or estate tax; gifts above certain allowances are merely treated as taxable income for the recipient. For employees working on a salary for a Mexican employer, RESICO does not apply: regular income tax plus social security contributions apply here, which together can quickly exceed 40%. Where the line runs: RESICO covers income from self-employment, professional work and smaller businesses, not employment income, and the legal form does not matter as long as the turnover cap is respected and the activity is genuinely self-employed, not merely declared as such. What the proposed 2027 changes to the cap would mean is covered in the article on the RESICO 2027 threshold.
Leaving your home country: what to watch
Mexico is not a low-tax country: its top personal income tax rate is 35%, combined with a corporate tax rate of 30%. Moving there does not, on its own, end your tax residence at home. Whether it ends, whether an exit tax applies to shareholdings in companies, and how a tax treaty between your home country and Mexico divides the taxing rights depends on where you come from. What is true everywhere: a properly documented departure, including deregistration where your country has it and a genuine giving up of your home, should always be planned separately from the question of whether and how you become taxable in Mexico. Dual-residence arrangements with larger company holdings deserve particular care.
Practical steps after arrival
As soon as your residence card has arrived, you quickly need two numbers that are a prerequisite for almost every further step: the CURP, your population register number, which is issued automatically with the residence card, and the RFC, your tax number with the SAT, which you have to apply for separately. Since 2026 Mexico has also been rolling out a biometric CURP with fingerprints, iris scan and facial photo, which is intended to become the central identity feature for dealings with authorities and banks. As of 2026, however, it is only available in some states, and the classic CURP remains valid. Only once you have your CURP and RFC does the next step, the Mexican bank account, make sense. And only once you have a clear answer on your tax residence should you decide whether you want an RFC at all: if you earn no Mexican income and deliberately avoid tax residence, you may not need it in full.
Two decisions, not one
In the end, the whole residence question for Mexico comes down to two separate decisions that many people relocating mistake for one: which residence permit you apply for, and where you actually want to be tax resident. Both decisions can be made independently, but only if you consciously keep them apart from the start, instead of having a tax adviser sort them out after the fact when the first tax return is due, or worse, when an authority at home asks of its own accord where your centre of life actually is.
If you want to find out whether your particular mix of income would make you tax resident in Mexico, how RESICO works out for your situation and what a proper departure from your home country looks like, get an individual review before you file your application at the consulate.
