Every year, more Americans decide to retire in Mexico. The reasons are easy to understand: a lower cost of living, warmer weather, and a slower pace of life within a few hours' flight of family back home.
What's less understood is how much planning it takes to make that move work financially. Retiring abroad isn't just a lifestyle change. It changes how your money is taxed, how your accounts are managed, and how your estate plan holds up. Here's what to think through before you go.
Your US Tax Obligations Don't Disappear
A common misconception is that moving to Mexico means leaving the US tax system behind. It doesn't. The US taxes citizens on their worldwide income, no matter where they live. If you retire in Mexico, you'll likely still need to file a US tax return every year.
Mexico may also tax you, depending on where you maintain your home and whether you become a Mexican tax resident. The two countries have a tax treaty designed to prevent double taxation, but applying it correctly takes care. This is an area where getting it wrong is expensive, and it's worth working with professionals who understand both systems.
Your US Accounts May Not Travel With You
Many people are surprised to learn that some US brokerage firms and banks restrict or close accounts once they find out the account holder lives outside the US. This varies by institution, but it's common enough that it deserves attention before you move, not after.
Before relocating, it's worth checking with your custodian directly about their policy for non-US residents, and having a plan for where your accounts will be held going forward.
Retirement Account Rules Get More Complicated
IRAs, 401(k)s, and Social Security all continue to work while you live abroad, but the details matter. Required minimum distributions still apply. Withholding rules can change. And depending on your visa and residency status in Mexico, you may need to report foreign accounts or income there too.
None of this makes retiring abroad impractical. It just means your withdrawal strategy needs to account for both countries, not just the one you're leaving.
Your Estate Plan May Not Work the Way You Think
A will or trust drafted under US law doesn't automatically apply the way you'd expect if you own property or hold assets in Mexico. Property law in Mexico works differently, especially around real estate, and a plan that works cleanly in California may create complications for your heirs south of the border.
If you own or plan to buy property in Mexico, this is worth addressing directly with an estate attorney familiar with both systems, ideally before you buy.
Healthcare and Insurance Need a Real Plan, Not an Assumption
Medicare generally doesn't cover care outside the US. Many retirees in Mexico rely on private insurance, Mexico's public IMSS system, or a mix of both. This is a separate decision from your financial plan, but it affects your budget significantly enough that it belongs in the same conversation.
The Bottom Line
Retiring in Mexico can be a great decision. But it works best when it's treated as a financial plan, not just a move. Taxes, accounts, estate planning, and healthcare all need to be looked at together, ideally with advisors who understand both sides of the border.
If you're considering this move, or you've already made it and want a second look at how everything fits together, I'd welcome the conversation.

US and Mexican tax, residency, property, and healthcare rules are complex, change over time, and depend on your specific circumstances. Consult qualified tax, legal, and immigration professionals in both countries before making decisions about retiring abroad.
