Mexico Tax Guide for Expats: What Residente Temporal Holders Actually Pay

Tax Residency in Mexico

Mexico considers you a tax resident if you have a permanent home in the country or if your center of vital interests is in Mexico. For most expats holding a Residente Temporal visa and living in Mexico full-time, tax residency is established quickly — often from the date of arrival if you set up a permanent home.

Tax residents are taxed on worldwide income, while non-residents are taxed only on Mexico-sourced income at rates that vary by income type. Understanding your residency status is critical because it determines not only what income is taxable but also which deductions and treaty benefits you can access.

Progressive Tax Brackets

Mexico's personal income tax (ISR — Impuesto sobre la Renta) operates on a progressive scale with rates from 1.92% to 35%. The brackets for annual income in 2026 are approximately:

• MXN 0 - 8,952: 1.92%
• MXN 8,953 - 75,984: 6.4%
• MXN 75,985 - 133,536: 10.88%
• MXN 133,537 - 155,229: 16%
• MXN 155,230 - 185,852: 17.92%
• MXN 185,853 - 374,837: 21.36%
• MXN 374,838 - 590,796: 23.52%
• MXN 590,797 - 1,127,926: 30%
• MXN 1,127,927 - 1,503,902: 32%
• MXN 1,503,903 - 4,511,707: 34%
• Above MXN 4,511,707: 35%

For a digital nomad earning the equivalent of USD 60,000 (approximately MXN 1,080,000), the effective tax rate would be roughly 22-25% before deductions.

Social Security Contributions

If employed by a Mexican company, both employer and employee contribute to IMSS (Instituto Mexicano del Seguro Social). Employee contributions are relatively modest — approximately 2.8% of salary — covering healthcare, disability, retirement, and housing (INFONAVIT). Employer contributions are significantly higher, around 20-25% of payroll.

Self-employed expats and freelancers may opt into IMSS voluntarily or arrange private health coverage, which is common among the international community.

The Regime de Incorporacion Fiscal

Small businesses and freelancers earning under certain thresholds may qualify for the Regimen Simplificado de Confianza (RESICO), which offers flat tax rates of 1-2.5% on gross income. This regime could be remarkably advantageous for expat freelancers and small business owners, though it comes with limitations on deductions and is subject to specific eligibility criteria.

Deductions for Expats

Mexican tax law allows several personal deductions that can meaningfully reduce your tax burden:

• Medical and dental expenses: For yourself, spouse, and dependents
• Hospital expenses: Including insurance premiums for medical coverage
• Mortgage interest: On your primary residence in Mexico
• Charitable donations: To authorized Mexican institutions
• School transportation: For children attending school
• Retirement account contributions: Voluntary contributions to Afore accounts

The total deduction is capped at approximately 15% of gross income or five times the annual UMA (Unidad de Medida y Actualizacion), whichever is lower. For 2026, this cap is approximately MXN 198,000.

Double Taxation Treaties

Mexico has an extensive network of double taxation agreements with over 60 countries, including the US, UK, Canada, Germany, France, and Spain. These treaties prevent the same income from being taxed in both Mexico and your home country, typically through tax credits or exemptions.

For US citizens living in Mexico (who must file US taxes regardless of residency), the Foreign Earned Income Exclusion (FEIE) and Foreign Tax Credit (FTC) provide relief. The FTC is often more beneficial for high earners, as it allows dollar-for-dollar credit for Mexican taxes paid against US tax liability.

Property and Capital Gains

Capital gains on property sales in Mexico are taxed at rates up to 35%, but there is an exemption for the sale of a primary residence (once every three years, up to a value of approximately 700,000 UDIs). Investment income, including dividends and interest, is subject to withholding taxes that vary by source and residency status.

Practical Considerations

Mexico's tax year runs from January to December, with annual returns due by April 30. Monthly provisional payments are required for self-employed individuals and businesses. The SAT (Servicio de Administracion Tributaria) has modernized significantly, and most filings can be done electronically.

One important note: Mexico requires electronic invoicing (CFDI) for all business transactions. If you are freelancing or running a business, you will need to obtain your e-firma (electronic signature) and generate CFDIs for every invoice. This process can be navigated with the help of a local contador (accountant).
