Working from a café in Roma Norte doesn't make your income tax-free. If you're an American working remotely from Mexico, you likely owe taxes to the IRS — and potentially to Mexico too. Here's how it actually works.
It depends on how long you stay. Mexico uses the 183-day rule: if you spend 183+ days in Mexico in a calendar year, you become a tax resident and owe Mexican taxes on worldwide income. Under 183 days, Mexico generally doesn't tax your remote income — but the US still does. Many digital nomads try to stay under 183 days, but if you're based in Mexico year-round, you're likely a tax resident whether you've registered or not.
Mexico's tourist visa (FMM/FMN) technically doesn't authorize "work" in Mexico. However, the legal grey area for remote workers earning foreign income is widely tolerated. Immigration enforcement has focused on people working for Mexican employers without a work permit, not on Americans working remotely for US clients. That said, there's no formal digital nomad visa in Mexico as of 2026. The guide covers the practical reality and the risk factors.
If you're a freelancer or contractor, you owe 15.3% US self-employment tax (Social Security + Medicare) on net earnings — even if you qualify for the Foreign Earned Income Exclusion. The FEIE does not exempt you from self-employment tax. This is the #1 surprise for digital nomads in Mexico. On $100,000 of freelance income, that's $15,300 you still owe the IRS regardless of where you live.
If you're under 183 days in Mexico (not a Mexican tax resident), FEIE is usually your best option — it excludes up to $130,000 of earned income from US tax. If you're over 183 days and paying Mexican taxes, the Foreign Tax Credit may save more because Mexico's rates can exceed your US rate. The guide runs scenarios for both situations with 2026 numbers.
If you're a Mexican tax resident (183+ days), RESICO offers tax rates of 1-2.5% on gross income up to MXN 3.5M. It's designed for freelancers and small business owners. The low rate sounds amazing, but it means less Foreign Tax Credit to offset your US taxes. The guide calculates whether RESICO actually saves you money after both countries take their cut.

This depends on your former state. California, New York, and a few others are aggressive about claiming you're still a resident even after you move abroad. If you didn't properly establish non-residency before leaving, your state may still tax your income. The guide covers which states are problematic and the steps to cleanly sever state tax residency.
If you exceed 183 days, technically yes — you should register with SAT and get an RFC. In practice, many digital nomads don't, but this creates compliance risk. If you plan to stay long-term, register properly. The guide covers the RFC registration process step-by-step and what it means for your tax obligations. Read about visa options →
Coworking spaces in CDMX (WeWork, Selina, Homework) run $100-250/month. In Mérida and Oaxaca, $50-150/month. If you're self-employed, these may be deductible business expenses on your US return. The guide covers which Mexico-related expenses are deductible for US tax purposes. Full cost of living breakdown →
