1 Moving your money (USD → MXN)
USD→MXN is a high-volume corridor; spreads vary widely between banks, remittance apps, and mid-market specialists.

2 Banking as an American in Mexico
Practically, you need temporary or permanent residency plus a CURP to open most Mexican bank accounts. Tourists can sometimes open limited accounts, but residency makes it routine.
Local banks generally accept US persons under the FATCA agreement, though some are cautious about the extra reporting.
3 Taxes — the part everyone gets wrong
The US side (you still file)
- You file a US return on worldwide income. FEIE or the Foreign Tax Credit usually prevents true double taxation — which one wins depends on your income and local rates.
- FBAR (FinCEN 114) if your foreign accounts top $10,000 combined at any point in the year.
- FATCA (Form 8938) may also apply above higher thresholds.
The Mexico side
Mexico has no special expat tax regime. Note the US–Mexico totalization (Social Security) agreement was signed but is not in force, so double Social Security coverage can apply to the self-employed — verify current status.
Where this gets people
- Cross the 183-day residency line and Mexico can tax your worldwide income — not just Mexican-source income — on top of your US return.
- No Social Security totalization agreement — the self-employed can face double Social Security coverage. Plan for it.
- You generally can't open a local bank account until residency is sorted — arrange a transfer/multi-currency account for the gap.
- A "special regime" headline rate is not your effective rate — eligibility and exclusions matter a lot.
- State taxes can follow you abroad depending on the US state you left — don't assume you're done with them.
Cross-border tax is fact-specific and the penalties are real. A US-expat tax specialist handles FEIE/FTC, FBAR, and FATCA correctly.

US brokers sometimes drop customers with a non-US address. A broker that explicitly supports non-resident Americans is the standard fallback. Beware buying local (non-US) funds — PFIC (Passive Foreign Investment Company) rules make them a US tax nightmare.

Legal residents generally gain access to Mexico's public health system, but there's usually a gap before residency and coverage kick in. Many new arrivals and nomads bridge the gap with international coverage.

Your residency route determines your tax residency and bank access — they're connected.
Frequently asked questions
Do Americans living in Mexico still have to file US taxes?
Yes. US citizens file with the IRS on worldwide income no matter where they live. The US–Mexico tax treaty and tools like the Foreign Earned Income Exclusion (FEIE) or the Foreign Tax Credit usually prevent true double taxation, but you still must file. This is general information, not tax advice.
Do I need to file an FBAR if I move to Mexico?
If your foreign financial accounts add up to more than $10,000 at any point in the year, you generally must file an FBAR (FinCEN Form 114). Many expats also have FATCA (Form 8938) obligations. Penalties for missing these are steep — confirm your situation with a cross-border professional.
What's the cheapest way to move money to Mexico?
For a relocation lump sum, the cost is almost entirely the exchange-rate spread, not the visible fee. Banks commonly bury 1–3% in the rate. Compare your specific amount with the transfer cost tool before sending.
Can I keep my US brokerage account after moving to Mexico?
Some US brokers restrict or close accounts once you have a non-US address. A broker that explicitly supports non-resident Americans is the common fallback. Don't change your address until you've confirmed your broker's policy.
