US Expats in Mexico
~1,500,000 US citizens Americans live in Mexico. Here's what you need to know about managing your finances, staying compliant, and making the most of the US-Mexico tax treaty.
The US-Mexico relationship is anchored by a tax treaty ratified in 1994 and a totalization agreement that prevents double Social Security taxation. American residents in Mexico typically face an effective tax rate of 1.9-35%, with Mexican Peso (MXN) as the local currency. The largest US expat communities are concentrated in Mexico City, Guadalajara, Monterrey, Cancun and Puerto Vallarta.
Beyond US obligations like Form 1040, FBAR, and Form 8938, US persons in Mexico must navigate 1 country-specific filing (detailed below) alongside the PFIC rules that affect most local mutual funds. The keys to staying compliant: track every MXN account against the $10,000 FBAR threshold, avoid local pooled investment products unless they qualify as QEFs, and reconcile foreign tax credits against the treaty rules.
