US Social Security retirement benefits are paid to eligible recipients regardless of where they live, with very few country exceptions (Portugal is not one of them). If you have earned sufficient work credits to qualify for Social Security retirement benefits and you relocate to Portugal, your monthly benefit continues to be deposited into your US bank account on the same schedule as if you remained in the United States. There is no reduction in benefit amount based on foreign residency.

Direct deposit into a US bank account is the standard payment method for Americans living abroad. The Social Security Administration (SSA) can also arrange direct deposit into a bank account in certain foreign countries, though processing through a US account and then transferring to Portugal is typically more reliable and provides better exchange rate control. You should notify the SSA of your change of address when you relocate to Portugal, as the agency sends periodic correspondence about benefit adjustments, financial documentation, and eligibility verification.

Spousal benefits, survivor benefits, and disability benefits also continue during foreign residency under the same rules. If your spouse receives benefits based on your work record, those payments continue when either or both of you live in Portugal. The US-Portugal totalization agreement (discussed below) may also affect benefit calculations for Americans who have worked in both countries.

The United States and Portugal have a bilateral totalization agreement (Social Security Agreement) that serves two purposes: preventing double social security regulation for Americans working in Portugal, and allowing workers to combine work credits from both countries to qualify for benefits in either system. If you work in Portugal through the fund investment Golden Visa route, this agreement determines whether your Social Security contributions are paid to the US system (SSA) or the Portuguese system (Seguranca Social), and how credits from both systems are counted toward benefit eligibility.

Under the agreement, an American employee or self-employed worker sent to Portugal by a US employer for up to 5 years continues to pay US Social Security finances and is exempt from Portuguese social security contributions. This avoids double regulation on the same employment income. If your assignment exceeds 5 years or if you are locally employed in Portugal, you pay into the Portuguese system. The totalization agreement then allows you to combine US and Portuguese work credits to meet eligibility thresholds in either country — for example, if you need 40 quarters of US coverage but only have 30 from US employment, your Portuguese contributions can fill the gap.

For Golden Visa holders who do not work in Portugal (the majority of optionality and fund-route investors), the totalization agreement has minimal practical impact because there is no Portuguese employment generating social security contributions. The agreement becomes relevant primarily for business route investors who are actively employed or self-employed in Portugal, and for American retirees who take part-time work in Portugal after relocating.

Americans who delay Medicare Part B enrollment beyond their initial eligibility period (typically age 65 or the end of employer coverage, whichever is later) face a late enrollment penalty that permanently increases their Part B premium by 10 percent for each full 12-month period they could have had Part B but did not enroll. This penalty applies for the rest of the beneficiary's life. For Americans living in Portugal who do not need Medicare because they are using Portuguese healthcare, the question is whether to maintain Part B enrollment to avoid future penalties or to let it lapse and accept the penalty if they later return to the United States.

There is no exception to the late enrollment penalty for Americans living abroad. Unlike employer coverage, which provides a Special Enrollment Period when it ends, living outside the US and using foreign healthcare does not create a qualifying exception. If you are 65, live in Portugal, and choose not to enroll in Part B because you do not need it, you will face a permanent 10 percent penalty per year of non-enrollment if you later return to the United States and need Part B coverage.

The planning decision depends on your long-term outlook. If you plan to return to the US eventually (even years in the future), maintaining Part B enrollment preserves your premium rate and avoids the penalty. If you have obtained Portuguese citizenship and plan to remain in Europe permanently, the Part B premium may be an unnecessary expense. Most American retirees in Portugal maintain Part B enrollment as insurance against the possibility of future return, treating the monthly premium ($174.70 per month for standard income levels in 2026) as a relatively inexpensive hedge against a potentially significant future penalty.
