Mexico Taxes for Digital Nomads

Mexican tax on digital nomads is structurally simple but has two important wrinkles: a stricter-than-headline residency test (days alone are not enough), and a progressive ISR rate that rises quickly into mid-30s for six-figure earners. The key decision is whether to become a tax resident at all — many nomads structure their first years in Mexico to stay under the threshold.

When does Mexico tax you?

Mexican tax residency under the Código Fiscal de la Federación (CFF) turns on the center of vital interests test, not just days. You are a Mexican tax resident if:

• You have a primary home in Mexico and your center of vital interests is in Mexico (more than 50% of your income comes from Mexican sources, or your main professional activity is in Mexico), or
• You stay more than 183 days in a year and cannot demonstrate your center of vital interests is abroad.

Practically: a nomad who spends 9 months in Mexico but whose income comes entirely from a US employer, who maintains a US address/bank/health coverage, often successfully argues non-resident status. The SAT allows rebuttal, but the paperwork trail must be consistent.

Non-resident taxation

Non-residents pay Mexican tax only on Mexican-source income. For a remote worker paid by a foreign employer into a foreign bank, that is typically zero. Mexican rental income, capital gains on Mexican property, and Mexican-employer salary are taxed even for non-residents, at flat rates ranging 15–35%.

Resident taxation — 2026 ISR progressive scale

At an exchange rate near 20 MXN/USD, the 30% bracket starts around $29,500 USD/year taxable; the 35% top rate applies above ~$225,000 USD/year. The SAT does not allow a foreign-earned-income exclusion equivalent to the US FEIE, so resident nomads pay tax from the first peso of worldwide income.

The US-citizen wrinkle

The US–Mexico tax treaty and FTC prevent double taxation in practice:

• US citizens remain liable for US tax on worldwide income regardless of Mexican residency.
• If Mexican-resident, file Mexican annual return (Declaración Anual) by April 30. Mexican tax paid becomes a Foreign Tax Credit on the US return.
• FEIE (~$126,500 for 2025) can exclude a chunk of income from US tax if you meet the physical-presence or bona-fide-residence test.
• If non-resident in Mexico (under the 183-day + center-of-interests test), only US tax applies — the simpler path for short-to-medium stays.

Many US nomads structure their first year or two in Mexico to stay under tax residency by splitting time with another country. After that, if Mexico is "home" in a real sense, tax residency often follows naturally and the planning shifts to FTC/FEIE optimization.

IVA (VAT) and business activity

Mexico imposes IVA (Impuesto al Valor Agregado) at 16% on most goods and services. If you register as a freelancer in Mexico (Persona Física con Actividad Empresarial) and invoice Mexican clients, you charge and remit IVA. Foreign-client invoices from a Mexican-registered freelancer are zero-rated. Most nomads with only foreign clients avoid Mexican business registration and remain non-residents, sidestepping IVA entirely.

Social security

Temporary Resident visa holders are not automatically enrolled in IMSS (Mexican social security). Private health insurance is the typical route — see cost-of-living for typical pricing. Enrolment in IMSS is voluntary for non-employed residents (annual fee ~$350–800 USD depending on age).

Double-tax treaties

Mexico has treaties with over 60 countries including the US, Canada, UK, Spain, Germany, and all major Latin American economies. Treaties define source-country taxing rights and usually include a tie-breaker article for individuals resident in both countries. Before filing the first Mexican annual return, confirm treaty residence via a tax advisor.
