U.S. Expat Investing Abroad: Why “Going Local” Is Often the Wrong Move

For many Americans, the decision to move abroad begins as a lifestyle conversation. Better weather, lower costs, a slower pace, more freedom. Popular destinations like Portugal, Spain, Mexico, Costa Rica, and Thailand continue drawing retirees and remote workers who are ready for a different version of daily life.

The mistake most people make is treating the move primarily as a travel decision rather than a financial planning decision. Your U.S. financial life does not pause when you leave the country. And if the structure is wrong before you go, the cleanup afterward can be expensive and complicated in ways that were entirely avoidable.

The biggest misconception about moving abroad

A surprising number of Americans assume that leaving the United States means stepping outside the U.S. financial and tax system. That is not how it works.

The United States taxes its citizens on worldwide income regardless of where they live. That means you still file U.S. taxes while living abroad, your investment accounts still fall under U.S. rules, and certain foreign investments can create severe and largely avoidable tax problems for Americans who do not know what to look for.

Foreign bank account reporting requirements may also apply depending on the balances held, and retirement account contribution eligibility can become more nuanced depending on how foreign income exclusions interact with your overall tax picture. These are not obscure edge cases. They affect a significant number of Americans living abroad who simply were not told about them before they left.

The investing mistake that catches expats off guard

After relocating, many Americans eventually get approached by a local bank, insurance company, or financial advisor offering investment products. Foreign mutual funds, local retirement vehicles, insurance-based investment plans, and unit trusts may all be presented as straightforward options for building wealth in your new country of residence.

For Americans, this is where serious problems often begin.

Many foreign investment vehicles are classified by the IRS as Passive Foreign Investment Companies, or PFICs. The tax treatment on PFICs is punitive by design, and the reporting requirements are burdensome enough that they can create ongoing accounting costs that far exceed any benefit the investment itself might offer.

This is not about being inflexible or ignoring local options. It is about understanding that the U.S. tax code was not designed with expat investors in mind, and that the default assumptions embedded in foreign financial products can create problems that take years and significant professional fees to unwind.

Why your choice of custodian matters more abroad

Many Americans do not think carefully about their financial custodian until they are already abroad and starting to encounter friction. By then, the options for making changes without disruption are more limited.

For Americans living internationally, Charles Schwab is frequently one of the strongest custodial options available, for several reasons that compound over time.

Schwab reimburses ATM fees worldwide on certain accounts. For someone living abroad and regularly accessing local currency, this eliminates a persistent and irritating friction point that adds up meaningfully over months and years.

Schwab also maintains a stable U.S.-based brokerage infrastructure that functions well for internationally mobile clients. Many traditional U.S. financial institutions become restrictive once a client establishes foreign residency, in some cases closing accounts or refusing to service them entirely. Schwab has historically been more accommodating for clients who maintain a U.S. address while living abroad.

For retirees and pre-retirees specifically, maintaining continuity between investment management, retirement account withdrawals, tax planning, and cash flow becomes increasingly important once international living enters the picture. The objective is stability and simplicity, not rebuilding financial infrastructure every time your location changes.

How international living changes retirement planning

One of the more counterintuitive aspects of moving abroad is that it tends to increase financial planning complexity rather than reduce it. The lifestyle may simplify. The financial picture often does not.

Coordinating retirement account withdrawals across international tax residency rules requires understanding how your country of residence treats U.S.-sourced income, whether a tax treaty exists between the U.S. and that country, and how that treaty interacts with your specific account types. Getting this wrong can mean paying taxes in two jurisdictions on the same income.

Roth conversion opportunities, which can be powerful tools for managing long-term tax exposure, may become more or less attractive depending on your foreign tax situation. Sequence of returns risk, the danger of experiencing poor market performance early in retirement, does not diminish when you move abroad. It becomes more consequential when your withdrawal needs are fixed in a foreign currency and your assets are denominated in U.S. dollars.

Healthcare is another dimension that requires explicit planning. Access to quality English-speaking providers, private insurance availability, and the cost of that insurance vary enormously by country. Medicare does not cover care received outside the United States, which means retirees living abroad need a separate insurance structure entirely.

What to address before you leave

The Americans who tend to transition abroad most successfully are usually not the ones who found the cheapest destination. They are the ones who did the financial planning work before the move, not after.

Tax residency rules deserve early attention. Different countries determine tax residency by different criteria, some based on days present, others on domicile or intention, and dual tax exposure can become complicated quickly if you do not understand where you stand before you establish a new residency.

Estate planning documents may need to be updated or supplemented. International living can create additional complications around wills, beneficiary designations, and asset titling that a standard U.S.-focused estate plan does not address. Some countries have forced heirship rules or other legal structures that interact with U.S. estate plans in unexpected ways.

Banking access should be confirmed before departure, not assumed. Some U.S. institutions will restrict or close accounts once they become aware a client has established foreign residency. Identifying which institutions will continue to serve you, and setting up the right relationships in advance, is significantly easier to do before you leave.

Currency risk is worth explicit consideration. If your living expenses will be denominated in a foreign currency while your retirement assets remain invested in U.S. dollars, a shift in exchange rates can meaningfully affect your purchasing power in ways that a purely domestic retirement plan would not encounter.

The connection to retirement income planning

International living does not change the fundamental principles of sound retirement income planning. It adds a layer of complexity on top of them.

A well-structured retirement income plan, one that coordinates withdrawals across account types, manages sequence of returns risk, optimizes for tax efficiency over time, and maintains flexibility as circumstances change, is arguably more important for someone living abroad than for someone staying in the United States. The margin for error is smaller when you are operating across multiple tax systems, currencies, and healthcare structures simultaneously.

Working with a fee-only fiduciary advisor who understands the intersection of international living and U.S. retirement planning is one of the highest-value steps an expat or prospective expat can take. The complexity involved requires someone whose incentive is the quality of your outcome, not the sale of a product.

If this was useful, consider sharing it with someone planning an international move who has not yet thought through the financial side.
