Moving to Mexico from the US: The US-Specific Checklist Most Guides Skip

Every general “how to move to Mexico” guide covers the same ground: visas, banking, housing. What almost none of them cover is the handful of things that are specific to being a US citizen, obligations that don’t disappear just because you’ve relocated. This is the checklist Paul walks US clients through separately from the general relocation sequence.

Pair this with the 180 day checklist.

For the visa side of this checklist specifically, a Visa Strategy Call catches the US-specific timing issues before they become a problem.

Your US Bank Accounts: Keep Them Open, Don’t Close Them

Closing US accounts before you move is one of the most common early mistakes. Keep at least one US checking account and one US-based card active, you’ll need them for Social Security deposits, US tax payments, and any US-based income. Notify your bank of your move (an address change to a Mexican address can trigger a fraud freeze if they’re not expecting it), and set up a US mailing address you actually control before you leave, not after.

US Mail Doesn’t Stop Existing: Route It Before You Leave

A USPS forwarding order is not a long-term solution; it expires and Mexican delivery isn’t reliable enough to depend on for anything official. Most of Paul’s clients set up a US-based virtual mailbox service (scans and forwards mail digitally) before departure, and use that address for banks, the IRS, and any account that still requires a US mailing address on file.

US Taxes Follow You: Residency Doesn’t Change That

The US taxes citizens on worldwide income regardless of where they live. Moving to Mexico does not end your US federal filing obligation. Two things catch people off guard: FBAR reporting (required once your combined foreign account balances exceed $10,000 at any point in the year) and FATCA reporting on the same accounts. Neither is optional, and penalties for missing them are disproportionate to the paperwork involved. If your home state has an income tax (California and a few others are notoriously aggressive about this), you may also need to formally establish non-residency, simply moving isn’t always enough on its own. This is a conversation for a cross-border accountant, not a Google search.

Social Security Keeps Paying: Medicare Doesn’t Follow You

Social Security direct deposit continues uninterrupted to a US bank account (Wise or a direct-to-Mexico deposit are both workable, but most clients keep the US account as the landing point and move funds from there). Medicare is the opposite story: it does not cover care received in Mexico, full stop. Budget for IMSS Voluntario or private insurance from day one, don’t assume Medicare has your back once you’re outside the US.

You Can Still Vote

US citizens living abroad remain eligible to vote in federal elections via the Federal Voting Assistance Program (FVAP.gov). Register before you leave or from Mexico, most states accept an emailed or faxed absentee ballot request from overseas citizens.

Your US Driver’s License Still Matters

A valid US license plus an International Driving Permit (available from AAA before you leave, valid for one year) covers most situations while you sort out a Mexican license. Renew your US license before departure if it’s close to expiring, renewing it later from Mexico is possible in most states but adds friction you don’t need in your first year.

Passport Runway: 18 Months, Not 6

Mexican immigration and most Mexican bureaucratic processes want to see meaningful passport validity, not the bare minimum. Renew before you go if you’re inside 18 months of expiration, doing it from Mexico through a US consulate is possible but adds weeks you don’t want to lose mid-process.

The One-Sentence Version

Nothing about being American pauses when you cross the border, taxes, Social Security, voting rights, and banking relationships all continue, and the moves that go smoothly are the ones where these were set up correctly before departure, not patched together after a problem shows up.

State Residency: The Loose End That Bites Hardest

Your federal taxes follow you forever, but your STATE is a choice, and an expensive one to leave unmade. High-tax states like California can continue treating you as a resident (and taxing you) if you keep enough ties: a driver's license, voter registration, property, even a storage unit can factor in. Before you leave, deliberately establish domicile in your final US state, many expats use the mail-forwarding-plus-domicile services built for RVers in states with no income tax like Florida, Texas, or South Dakota, then sever the old state's markers methodically. One afternoon of paperwork now versus a residency audit later: easy trade.

The full US-departure sequence, state domicile, mail, banking, Social Security, and the timing that makes them interlock, is built into the 180-Day Action System, and if your situation has moving parts (a house sale, a business, a pension), a Visa & Immigration Strategy Call gets the order of operations right the first time.

Frequently Asked Questions

Do I still have to file US taxes after moving to Mexico?

Yes, US citizens are taxed on worldwide income wherever they live. You may also need to file an FBAR if combined foreign account balances exceed $10,000 at any point in the year. Confirm details with a cross border tax professional.

Should I close my US bank accounts before moving to Mexico?

No. Keep at least one US checking account and one US card active for Social Security deposits, US tax payments and any US income. Tell your bank about your move so it does not freeze the account for unusual activity.

Can I still vote in US elections while living in Mexico?

Yes, US citizens abroad can vote in federal elections through the Federal Voting Assistance Program. Register before you leave or from Mexico. Most states accept an emailed or faxed absentee ballot request, but rules vary by state.

How long should my US passport be valid before I move to Mexico?

I advise renewing if you are within 18 months of expiration, since renewing from Mexico adds weeks mid process. Consulates often ask for six months of validity as a minimum, so confirm the requirement for your appointment.

Can my old US state still tax me after I move to Mexico?

Possibly. High tax states like California can keep treating you as a resident if you keep ties such as a driver's license, voter registration, property or even a storage unit. Confirm your state's rules with a tax professional.
