Retiring Abroad in 2026: Taxes, Healthcare & Social Security

More Americans than ever are exploring the idea of retiring outside the United States. The appeal is easy to understand: lower costs in many countries, access to different cultures, and the possibility of a more comfortable lifestyle on a fixed income. But retiring abroad is not simply a matter of packing your bags and forwarding your Social Security check.

The US has some of the most far-reaching tax laws in the world when it comes to citizens living overseas. Healthcare requires entirely different planning once you step outside Medicare's coverage area. And while Social Security generally follows you across borders, there are rules worth knowing before you assume your monthly benefit will arrive without issue.

This guide focuses on the big financial questions of expat retirement in 2026, covering US tax obligations, healthcare planning, Social Security mechanics, and how to think about cost-of-living differences in a practical, numbers-grounded way. It is not a destination ranking. Think of it as the financial framework you need before any destination decision makes sense.

One of the most common misconceptions about retiring abroad is the belief that leaving the US means leaving US taxes behind. In reality, the United States is one of only two countries in the world (the other being Eritrea) that taxes its citizens based on citizenship rather than residency. This means that as a US citizen or green card holder living abroad, you are generally still required to file a US federal tax return and report your worldwide income to the IRS each year.

This applies to income from most sources you might have in retirement:

• Traditional IRA and 401(k) withdrawals are taxable as ordinary income
• Roth IRA withdrawals are generally tax-free at the federal level, as they would be domestically
• Social Security benefits may be partially taxable depending on your total income
• Investment income from dividends, interest, and capital gains is reportable
• Rental income from any US properties you retain

There are two main mechanisms the IRS provides to reduce the risk of being taxed twice on the same income.

The Foreign Tax Credit (Form 1116) allows you to offset US taxes with taxes you have paid to a foreign government on the same income. For retirees drawing primarily from US-based accounts like IRAs and Social Security, this credit may offer limited relief, since those income sources are typically taxed only by the US.

The Foreign Earned Income Exclusion (FEIE, Form 2555) allows qualifying individuals to exclude a portion of foreign-earned income from US taxation. For 2024, the IRS set this exclusion at $126,500 (adjusted annually for inflation). However, this exclusion applies to earned income, meaning wages or self-employment income generated abroad. It does not apply to passive income sources like retirement account withdrawals, Social Security, dividends, or interest. For most retirees, the FEIE provides little direct benefit.

The practical takeaway is that expat retirees often carry a meaningful US tax filing obligation for life, regardless of where they reside. Many expats work with a tax professional who specializes in international taxation and US expat returns, since the rules are genuinely complex and vary depending on the tax treaty (if any) between the US and the country of residence.

The IRS maintains a list of US tax treaties with foreign countries on irs.gov, and these treaties can significantly affect how retirement income is taxed in your country of residence. Some treaties reduce or eliminate withholding on certain income types. Reviewing the relevant treaty with a qualified adviser is an important part of expat retirement planning.

One additional filing requirement worth knowing: US citizens abroad with foreign financial accounts exceeding $10,000 at any point during the year are generally required to file a FinCEN Form 114 (commonly called the FBAR) with the Financial Crimes Enforcement Network. Separately, certain foreign assets above thresholds defined by the IRS must be reported on Form 8938 under the Foreign Account Tax Compliance Act (FATCA). These are reporting requirements, not additional taxes, but the penalties for non-compliance can be significant. More detail is available at irs.gov.

Healthcare is arguably the most consequential financial variable in expat retirement planning, and the reality of Medicare abroad is not what many people hope it will be.

In most circumstances, Medicare does not cover healthcare services received outside the United States. This applies to Original Medicare (Parts A and B) and, in almost all cases, to Medicare Advantage plans as well. There are a very small number of limited exceptions, primarily involving situations where a foreign hospital is the closest available facility to a US border, but these do not apply to someone living full-time in another country. Medicare.gov outlines these exceptions in detail.

This creates what is sometimes called the Medicare overseas gap: you may be paying Medicare Part B premiums (which continue even while living abroad, if you want to preserve coverage for future US visits) while simultaneously needing to pay separately for healthcare in your country of residence.

Common approaches expat retirees explore to address this gap include:

• International private health insurance: Plans designed specifically for expats that provide coverage in the country of residence and often globally. Premiums vary significantly by age, health status, coverage level, and country.
• Local public health systems: Some countries allow long-term residents to access their national health systems, either free or at low cost. Eligibility and quality vary widely by country.
• Local private health insurance: In many countries, private insurance purchased locally is considerably less expensive than comparable US coverage.
• Self-funding: In countries with very low healthcare costs, some retirees absorb out-of-pocket medical expenses directly, particularly for routine care.

Healthcare costs are one of the major reasons retirees find certain countries financially attractive. In many popular expat destinations, high-quality private hospital care costs a fraction of equivalent US prices. But this advantage varies enormously by country and by individual health needs.

An important planning consideration: if you plan to return to the US for part of each year, maintaining Medicare Part B (and potentially a supplement) may still make sense for the coverage it provides during those periods. Letting Medicare Part B lapse and re-enrolling later typically results in a late enrollment penalty of 10% per year for each 12-month period you were eligible but not enrolled, as described on medicare.gov.

Our article on estimating total healthcare costs in retirement provides a useful framework for thinking about lifetime healthcare expenses, which applies whether you retire at home or abroad.

The good news for expat retirees is that Social Security generally follows you across borders. The Social Security Administration (SSA) can send payments to most foreign countries, either by direct deposit to a US bank account (which many expats maintain) or, where available, to a foreign bank account. The SSA publishes a comprehensive resource called Your Payments While You Are Outside the United States on ssa.gov, which lists every country where payments can and cannot be sent.

Currently, the SSA cannot send payments to a small number of countries, including Cuba and North Korea. Citizens of certain other countries may face restrictions depending on their status. Checking ssa.gov for the most current list is advisable before making location decisions that hinge on receiving Social Security abroad.

For most retirees in most countries, however, Social Security payments arrive reliably. The SSA also has totalization agreements with more than 30 countries as of 2025. These agreements are designed to prevent double taxation of Social Security taxes and to help workers who have split careers between the US and another country qualify for benefits from both systems. A full list of totalization agreement countries is available at ssa.gov.

Tax treatment of Social Security abroad is worth examining carefully. At the federal level, up to 85% of Social Security benefits may be subject to US income tax depending on your combined income, following the same rules that apply to US-based retirees. Some foreign countries also tax Social Security income received by their residents. Whether a US tax treaty reduces or eliminates that foreign taxation depends on the specific treaty. This is an area where a tax professional familiar with both US expat taxation and the laws of the destination country is genuinely valuable.

One additional point: the decision of when to claim Social Security does not change because you live abroad. The same tradeoffs between claiming early (as early as 62, at a reduced benefit) and delaying (up to age 70, for a higher benefit) apply regardless of your country of residence. If you are thinking through the timing question, our overview of the real math behind taking Social Security at 62 walks through the breakeven analysis in plain terms.

The financial case for retiring abroad often centers on cost-of-living arbitrage: using US dollar-denominated income (Social Security, retirement account withdrawals) to fund a lifestyle in a country where the dollar stretches further. This concept is sometimes called geoarbitrage, and when it works well, it can meaningfully change your retirement math.

To make this concrete, consider two illustrative hypothetical scenarios. These are educational examples only and do not reflect any specific individual's situation.

Hypothetical Scenario A: Retiring in a mid-cost US city
A retiree drawing $3,200 per month in income (combined Social Security and IRA withdrawals) might face monthly expenses of approximately $3,000 to $3,800 in a mid-tier US city, covering housing, food, transportation, healthcare, and discretionary spending. The margin for savings or unexpected expenses is narrow.

Hypothetical Scenario B: Retiring in a lower-cost country
That same $3,200 per month income in a country with significantly lower costs might cover a comfortable lifestyle at $1,800 to $2,500 per month, depending on the country, city, and individual lifestyle. The retiree now has a monthly surplus that could go toward travel, building an emergency fund, or reducing withdrawals from retirement accounts to allow more tax-deferred growth.

The scenarios above are purely illustrative. Actual costs vary dramatically depending on the country, the city within that country, lifestyle preferences, healthcare needs, and currency fluctuations. The US dollar's strength relative to local currencies is a real variable that can shift meaningfully over a multi-decade retirement.

Factors that reduce the cost savings of retiring abroad include:

• International health insurance premiums, which can be substantial for older retirees
• Travel costs to visit family and friends in the US
• Maintaining a US bank account and possibly a US mailing address
• US tax filing costs (expat tax preparation is typically more expensive than a standard US return)
• Currency risk: if your retirement country's currency strengthens against the dollar over time, your purchasing power in that country decreases
• Import costs for goods you prefer from the US

Factors that can amplify the savings include:

• Lower housing costs, particularly if renting rather than owning
• Lower food costs in markets and local restaurants
• Reduced or eliminated car expenses in walkable or transit-rich areas
• Lower out-of-pocket healthcare costs in countries with lower medical prices
• Reduced or eliminated state income taxes (since most US states do not tax non-residents on retirement income, though this varies - see our guide on state taxes in retirement for 2026 for more detail)

A useful exercise is to build a side-by-side monthly budget: your projected US retirement budget versus a projected budget in the country you are considering. Expatriate community forums, cost-of-living databases like Numbeo, and conversations with people already living in prospective destinations can provide grounded estimates to work from.

Beyond taxes, healthcare, and Social Security, several other financial and legal areas come into play for expat retirees.

Estate planning across borders. US estate and gift tax rules apply to US citizens regardless of where they live. The federal estate tax exemption is approximately $13.61 million per individual for 2024 (IRS Rev. Proc. 2023-34), but this is scheduled to revert to a lower level after 2025 unless Congress acts. In addition, the country where you reside may have its own inheritance or estate taxes. Having an estate planning attorney review your documents for cross-border compatibility is a step many expat retirees find valuable.

Required Minimum Distributions (RMDs). If you have traditional IRA or 401(k) accounts, RMDs generally begin at age 73 under current rules established by the SECURE 2.0 Act. Living abroad does not change this obligation. The IRS requires these distributions regardless of your country of residence, and they are taxable income in the year taken.

Banking access. FATCA has led some foreign banks to decline US citizen customers due to the compliance burden it imposes on them. This is a practical challenge some expats encounter when trying to open local bank accounts. Maintaining a US bank account with good international access features is something many expats prioritize.

Visa and residency requirements. Most countries require some form of visa or residency permit for long-term stays. Some have created specific retirement visas with financial requirements (proof of minimum income or assets). These are legal and immigration considerations that sit outside financial planning but directly affect the feasibility of any given destination.

Currency and withdrawal strategy. Retirees drawing from US-based accounts need a practical system for accessing money abroad. Wire transfer fees, foreign transaction fees, and exchange rate spreads can add up over time. Some retirees use accounts at banks or credit unions that reimburse foreign ATM fees and charge no foreign transaction fees. This is a small but practical detail that affects day-to-day life as an expat.

For retirees who are self-employed or running a small business while abroad, the tax and retirement account picture becomes more complex still. Our overview of self-employed retirement plans in 2026 covers the main account types worth understanding in that context.

Retiring abroad is a genuinely exciting possibility for many Americans, and for some it represents a path to a more comfortable, engaged, and financially sustainable retirement. But it rewards careful advance planning more than almost any other retirement decision. The US tax system does not switch off when you cross a border, Medicare coverage largely does not travel with you, and the cost-of-living savings can look different in practice than on a spreadsheet.

The good news is that millions of Americans live abroad in retirement successfully, and the financial mechanics are well understood once you dig into them. Working with professionals who have real experience in expat taxation, international health coverage, and cross-border estate planning can make an enormous difference in both the planning process and in the peace of mind you carry into retirement.
