Mexico has become one of the most popular destinations for American expats and digital nomads, with cities like Mexico City, Oaxaca, Playa del Carmen, and San Miguel de Allende attracting hundreds of thousands of US residents. Mexico’s proximity, relatively low cost of living, and growing digital nomad infrastructure make it an attractive first international move — but the tax implications on both sides of the border require careful attention.
This guide covers the Mexican 183-day tax residency rule, Mexican income tax (ISR) rates for expats, visa options and the RFC tax registration requirement, the US-Mexico 1992 tax treaty, and FBAR obligations for Mexican bank accounts. Whether you’re retiring, working remotely, or relocating for business, understanding both your US and Mexican obligations is essential before the 183-day clock starts ticking.
US citizens must file Form 1040 every year reporting worldwide income, regardless of where they live. Moving to Mexico — whether for retirement, remote work, or business — does not end your US tax obligations. The key tools Americans in Mexico use to avoid double taxation are: the Foreign Earned Income Exclusion (FEIE) and the Foreign Tax Credit (FTC).
The FEIE (Form 2555) allows you to exclude up to $126,500 of foreign earned income (wages, self-employment, freelance) from US taxation in 2024. To qualify, you must meet either the Physical Presence Test (330 days outside the US in a 12-month period) or the Bona Fide Residence Test (established a bona fide residence in a foreign country for a full tax year). Many Americans in Mexico who spend 11+ months there annually qualify easily under the Physical Presence Test. The FEIE covers earned income only — not passive income like dividends, interest, or capital gains. Self-employment tax (15.3%) still applies to self-employment income even with FEIE — this is a common surprise for US freelancers in Mexico.
If you pay Mexican income tax (ISR), you can use Form 1116 to credit those taxes against your US liability. For many lower-income expats in Mexico, Mexican ISR rates may be lower than US rates, making the FEIE more advantageous. For higher earners in Mexico’s top bracket (35%), the FTC may eliminate more US tax. Your CPA should model both options for your specific income level and composition. Note: you cannot use FEIE and FTC on the same income in the same year, though you can use FEIE for earned income and FTC for passive income.
The US-Mexico Income Tax Treaty (1992) prevents double taxation on most income types. Key provisions: salaries taxed primarily in country of work (Mexico taxes wages earned while physically in Mexico); business profits taxed in Mexico if permanent establishment exists there; dividends reduced withholding rates; US pensions generally taxable in US. The treaty includes a Savings Clause preserving US taxing rights over its citizens, so treaty benefits are limited for US citizens versus non-citizen residents, but the treaty’s FTC mechanism still prevents practical double taxation.
Mexico applies a 183-day rule for tax residency: if you spend 183 or more days in Mexico in a calendar year (consecutive or non-consecutive), you become a Mexican tax resident. From that point, Mexico taxes your worldwide income — not just Mexican-source income. Days are counted for the calendar year (January 1 – December 31). Before 183 days: you are a Mexican non-resident, taxed only on Mexican-source income (wages paid by a Mexican employer, rental income from Mexican property, etc.) at flat withholding rates (typically 25–30%).
Mexico’s income tax (ISR) uses a progressive rate structure for residents: effectively 1.92% on the lowest bracket rising to 35% on annual income above approximately MXN 3,000,000 (approximately $175,000). Middle brackets: ~30% on income above MXN 500,000 (~$29,000); ~32% above MXN 750,000 (~$44,000); ~34% above MXN 1,000,000 (~$59,000). For most digital nomads and retirees earning US-source income (remote work for US employer, US pension, US Social Security): the question is whether Mexico can tax that income once you become a Mexican tax resident. Under the US-Mexico treaty and general rules: Mexico as your country of residence can tax worldwide income once you establish residency. Remote work income for a US employer paid to a Mexican resident may be taxable in Mexico. This is a common compliance gap for digital nomads who assume their US-source income is invisible to the Mexican tax authority (SAT).
Servicio de Administración Tributaria (SAT) is Mexico’s tax authority, equivalent to the IRS. Mexican tax returns (Declaración Anual) are due April 30 for individuals. Filing is electronic via the SAT portal using your RFC number. Mexico has been increasing enforcement on foreign residents who fail to declare worldwide income — particularly targeting digital nomads with high foreign income who register for RFC but do not file annual returns.
Americans can enter Mexico visa-free for up to 180 days as a tourist (FMM — Forma Migratoria Múltiple). Beyond 180 days, a legal residency status is required: Residente Temporal (Temporary Resident): 1–4 years; requires proof of financial solvency (minimum approximately MXN 21,500/month ~$1,270/month in current income, or approximately MXN 300,000 ~$17,600 in savings/investments); can be renewed; allows working for Mexican employers with additional work authorization (Residente Temporal con permiso para trabajar). Residente Permanente (Permanent Resident): after 4 years of Temporary Residency, or immediately for those meeting higher income thresholds (approximately MXN 43,000/month ~$2,540/month) or with Mexican family ties. Note: having a Temporary or Permanent Resident status is not itself a tax trigger — the 183-day presence rule controls tax residency. However, Permanent Residents who have their “center of vital interests” (main home, family) in Mexico may be considered residents regardless of day count.
The RFC is Mexico’s tax identification number — equivalent to a US Social Security Number or EIN for tax purposes. RFC is required to: open a Mexican bank account as a resident; issue invoices (facturas) for business or freelance services; file Mexican tax returns; make certain large transactions. Americans with Residente Temporal or Permanente status can obtain an RFC at the local SAT office. The process requires your resident visa, passport, proof of address, and completed form. Getting RFC is not optional for legal residents — it’s a compliance requirement, not a choice. Once you have RFC, SAT expects annual tax returns if your income is above the minimum threshold.
Opening a Mexican bank account is practical for daily life (BBVA Mexico, Banamex/Citibanamex, Santander Mexico, Banorte, HSBC Mexico are common). All Mexican bank accounts must be reported on FBAR (FinCEN Form 114) if the aggregate maximum value of all foreign accounts exceeds $10,000 at any point. For most expats with a local operating account, this threshold is often reached quickly. FBAR is due June 15 (extended to October 15 automatically) and filed free via FinCEN’s BSA E-Filing System. Additionally, FATCA Form 8938 applies if total foreign financial assets exceed $200,000 at year-end or $300,000 at any point (single filers abroad).
Mexico’s diversity means the tax and cost implications vary significantly by location. Here is a brief overview of the most popular American expat destinations:
Latin America’s largest metropolis with a thriving digital nomad scene (Roma Norte, Condesa, Polanco neighbourhoods). Monthly cost for a comfortable single expat lifestyle: approximately $1,500–2,500/month. RFC registration: straightforward at SAT offices in CDMX. Growing US expat community with English-speaking accountants and lawyers familiar with dual US-Mexico tax obligations.
Growing arts and food scene; lower cost than CDMX (approximately $1,000–1,800/month). Smaller expat tax professional community — may need to work with Mexico City-based professionals or US expat CPA firms remotely.
Beach lifestyle, large international community. Costs higher than Oaxaca (approximately $1,500–2,500/month in Playa). Popular for retirees and remote workers. Quintana Roo has no state income tax (Mexico’s income tax ISR is federal-only — there is no additional state income tax layer like in the US).
Large established American retiree community; colonial architecture; year-round mild climate. Strong English-speaking professional services community. Costs approximately $1,500–2,200/month for comfortable living. Well-developed network of US expat CPAs and local accountants familiar with US-Mexico filing. An excellent base for retirees wanting established expat infrastructure and proximity to US (3-hour flight to most US hubs).

Transfer Money USA ↔ Mexico →Potentially yes, once you become a Mexican tax resident (after 183 days in a calendar year). As a Mexican tax resident, Mexico taxes your worldwide income — including wages paid by a US employer for work physically performed in Mexico. Under the US-Mexico treaty, wages are generally taxable in the country where the work is performed. If you are physically in Mexico working for a US employer, Mexico may claim the right to tax those wages once you establish residency. Most digital nomads who stay under 183 days avoid this issue. Those staying longer should get RFC and consult a tax professional about ISR obligations on their US salary or freelance income.
Yes, if you qualify. The FEIE (Form 2555) allows you to exclude up to $126,500 of foreign earned income in 2024. To qualify from Mexico, you typically use the Physical Presence Test (330 days outside the US in any consecutive 12-month period), which most full-time Mexico residents meet easily. The FEIE covers only earned income (wages, self-employment) — not US dividends, interest, capital gains, or Social Security. Important: self-employment tax (15.3%) is not eliminated by the FEIE — US freelancers and sole proprietors still owe SE tax on excluded income.
RFC (Registro Federal de Contribuyentes) is Mexico’s federal taxpayer identification number. You need it to open a Mexican bank account as a resident, issue business invoices, file Mexican tax returns, and make certain transactions. Legal residents of Mexico (Residente Temporal or Permanente) are expected to register for RFC. Without RFC, you’re limited in what financial and business activities you can conduct in Mexico. Getting RFC triggers an expectation from SAT (Mexico’s tax authority) that you will file annual tax returns if your income exceeds minimum thresholds.
Americans can stay in Mexico visa-free for up to 180 days on a tourist permit (FMM). For longer stays, Residente Temporal (1–4 years, renewable) is the most common route for expats. Requirements include proof of income (~MXN 21,500/month or ~$1,270/month) or savings (~MXN 300,000 or ~$17,600). After 4 years of Temporary Residency, you can apply for Permanent Residency. There is no specific digital nomad visa in Mexico, but the tourist permit and Residente Temporal visa serve most remote workers’ needs. Note: your visa status and tax residency are separate — even a tourist overstaying beyond 183 days is a Mexican tax resident for that year.
Yes, if the aggregate maximum balance of all your foreign financial accounts (not just Mexican) exceeds $10,000 at any point during the calendar year. You must file FinCEN Form 114 (FBAR) by June 15 each year (automatic extension to October 15). This covers BBVA Mexico, Banamex, Santander Mexico, and any other Mexican bank accounts. If total foreign assets exceed $200,000 at year-end or $300,000 at any point (single filers abroad), also file Form 8938 (FATCA) with your tax return. FBAR penalties for wilful non-filing can be 50% of account balance per year — this is not optional compliance.
