Retirement Abroad? Key Costs Merck Employees Should Consider Before You Go

Healthcare Provider Update: Healthcare Provider for Merck Merck & Co., Inc., commonly known as Merck, is a global leader in the healthcare sector, renowned for its innovative pharmaceuticals, vaccines, and biologic therapies. As a prominent healthcare provider, Merck delivers a wide array of health solutions targeting various health conditions, particularly in areas such as immunology, oncology, and infectious diseases. Potential Healthcare Cost Increases in 2026 In 2026, healthcare costs are projected to rise significantly, primarily driven by the anticipated expiration of enhanced federal premium subsidies associated with the Affordable Care Act (ACA) and growing medical expenses. Faced with an average premium increase of 18%, healthcare consumers may experience out-of-pocket costs climbing by over 75%. This situation is exacerbated by surging medical care prices, as hospitals and providers seek to balance inflationary pressures while maintaining profitability. As a result, many individuals may find themselves priced out of adequate health coverage, prompting essential discussions on the need for policy interventions. Click here to learn more

For decades, many Americans have dreamed about retiring abroad—whether for lifestyle reasons, proximity to family, or simply a change of scenery. For many Merck employees, the idea of enjoying retirement overseas after years of dedication can feel especially rewarding.

For individuals over 55 with substantial invested assets, retiring abroad may be possible. However, it requires careful planning. Moving overseas does not automatically simplify finances and, in some cases, it can increase complexity—particularly when retirement income includes employer-sponsored plans.

Before making a decision, there are several important financial considerations.

1. The U.S. Tax System Follows You

The United States generally taxes U.S. citizens on their worldwide income, regardless of where they live. This remains true even if a Merck employee establishes residency in another country.

That means:

- Traditional IRA and many employer-sponsored retirement plan withdrawals are generally taxable for U.S. purposes.

- Required Minimum Distribution (RMD) rules apply to most tax-deferred retirement accounts, such as traditional IRAs and many employer plans (though not to Roth IRAs for original owners).

- Social Security benefits may be taxable depending on income levels.

- Capital gains must continue to be reported.

- Depending on thresholds, foreign financial accounts and assets may need to be reported, including potential FBAR (FinCEN Form 114) and/or FATCA Form 8938 filings.

International tax compliance requirements remain in place after moving abroad, and penalties for noncompliance can be significant. U.S. citizens residing overseas typically continue to have federal filing obligations.

2. Medicare and Health Care Outside the United States

Medicare generally does not cover health care services received outside the United States, except in limited circumstances. Some Medigap policies may provide limited emergency coverage abroad, but traditional Medicare coverage is largely restricted to care received within the U.S. ¹

As a result, retirees living overseas often evaluate alternative health care arrangements, which may include purchasing additional coverage. For Merck employees accustomed to employer-sponsored health care benefits, this transition requires thoughtful comparison of costs and coverage.

Health care planning for retirees—including income-related Medicare premium considerations and broader long-term planning—can become more complex when residency changes.

3. Currency Risk

If retirement income is denominated in U.S. dollars but expenses are paid in another currency, exchange-rate fluctuations can affect purchasing power. This may be particularly relevant for Merck retirees relying on distributions from U.S.-based retirement accounts.

For example, a significant change in currency exchange rates can increase or decrease the effective cost of living when converting dollars into foreign currency. This exposure introduces additional variability that should be evaluated in long-term income planning.

4. Estate Planning Across Borders

Estate planning can become more complex when assets or beneficiaries span multiple jurisdictions. Merck employees who accumulate assets across different states or countries during their careers may already have layered estate considerations.

Many countries have forced heirship rules. Some impose inheritance taxes on local assets. Legal treatment of trusts may differ from U.S. law, and foreign real estate may require additional planning to align with U.S. estate documents.

When individuals own property or financial accounts outside the United States, coordination between U.S. estate planning documents and local legal requirements is often necessary.

Evaluating the Decision Carefully

Retiring abroad can be appealing for lifestyle and personal reasons. However, U.S. taxation of worldwide income, limited Medicare coverage outside the country, currency exposure, and cross-border estate planning considerations are important financial factors for Merck employees to evaluate before making a long-term move.

A thoughtful analysis should consider how relocation may affect income planning, tax obligations, health care arrangements, and legacy goals over the coming decades.
