Understanding Social Security in the US: For Nationals & Expats

Navigating the US Social Security system is vital for both nationals and expatriates. This guide covers eligibility (work credits, age), benefit calculations, and the impact of the Social Security Fairness Act, which eliminates WEP and GPO. It also details benefit types (retirement, disability, survivor) and crucial information for expats, including international eligibility, restricted countries, payment methods, and Totalization Agreements. Essential administrative, healthcare, and tax considerations for Americans living abroad are discussed, along with financial planning strategies for a secure retirement.

Introduction to social security in the us

The United States Social Security system operates as a federal social insurance program administered by the Social Security Administration (SSA), serving as a cornerstone of retirement security for millions of Americans. The system functions on a pay-as-you-go basis, where current workers contribute through payroll taxes to fund benefits for current retirees, disabled individuals, and survivors of deceased workers.

The program encompasses three primary types of benefits: retirement benefits for workers who have reached eligible ages and contributed to the system, disability benefits for those unable to work due to qualifying medical conditions, and survivor benefits for spouses, children, and dependents of deceased workers. Understanding this system is crucial for both U.S. nationals and expatriates for effective financial planning and ensuring access to earned benefits.

Eligibility Requirements

Work Credits

The foundation of Social Security eligibility rests on earning work credits through employment or self-employment. To qualify for benefits, you must earn 40 work credits, with a maximum of four credits available per year. In 2025, you earn one credit for every $1,810 in covered earnings, meaning you need to earn at least $7,240 annually to receive the maximum four credits.

These work credits represent your contribution to the Social Security system and serve as the basic qualification measure for all Social Security benefits. The credit system ensures that only those who have participated in the workforce and contributed to the system can receive benefits, maintaining the program’s insurance-based structure.

For younger workers, the credit requirement for disability benefits is lower, reflecting the reality that they may not have had sufficient time to accumulate 40 credits before becoming disabled. However, retirement benefits consistently require the full 40 credits, representing approximately 10 years of substantial work activity.

Age Requirements

Social Security retirement benefits become available as early as age 62, though claiming benefits at this age results in permanently reduced monthly payments. Your full retirement age (FRA) depends on your birth year and ranges from 65 for those born before 1938 to 67 for those born in 1960 or later.

For people born in 1958, the FRA is 66 years and 8 months, and for those born in 1959, it’s 66 years and 10 months. This gradual increase in retirement age reflects demographic changes and the system’s need to maintain long-term sustainability.

Delaying retirement beyond your FRA can significantly increase your monthly benefits through delayed retirement credits. These credits accumulate until age 70, at which point there’s no further advantage to delaying benefit claims.

Benefit Calculations

Primary Insurance Amount (PIA)

Social Security benefits are calculated using a formula that considers your highest 35 years of earnings, adjusted for inflation. The Social Security Administration uses these earnings to determine your Average Indexed Monthly Earnings (AIME), which then factors into calculating your Primary Insurance Amount (PIA).

The PIA represents the monthly benefit you would receive if you claim Social Security at your full retirement age. This calculation involves applying a progressive benefit formula to your AIME, which provides higher replacement rates for lower-income workers while still rewarding higher earners with larger absolute benefit amounts.

Benefit Adjustments

The timing of your benefit claim significantly impacts your monthly payment amount. Claiming benefits before your FRA reduces your monthly payment permanently, with reductions ranging from approximately 25% to 30% depending on how early you claim and your birth year.

Conversely, delaying benefits beyond your FRA increases your monthly payment through delayed retirement credits. These credits are worth 8% per year until age 70, meaning someone with an FRA of 67 who waits until 70 to claim benefits would receive 124% of their PIA.

Cost-of-living adjustments (COLA) help protect Social Security benefits from inflation, with adjustments made annually based on changes in the Consumer Price Index.

Recent Legislative Changes: The Social Security Fairness Act

Overview of Changes

The Social Security Fairness Act was signed into law on January 5, 2025, eliminating two provisions that had reduced benefits for millions of Americans: the Windfall Elimination Provision (WEP) and the Government Pension Offset (GPO).

The WEP had reduced Social Security benefits for individuals who received pensions from jobs not covered by Social Security, including many government positions and foreign employment. The GPO was even more restrictive, reducing Social Security spousal or survivor benefits by two-thirds of any non-covered pension amount.

Impact and Implementation

The amendments made by this Act apply with respect to monthly insurance benefits payable for months after December 2023, meaning the changes are retroactive to January 2024. This change affects approximately 3 million Social Security recipients who had been subject to these reductions.

The Act affects certain individuals who are eligible for Social Security benefits, but who also receive pensions from work that did not require the payment of Social Security payroll taxes. Examples of those affected include teachers, police officers, firefighters, and other public servants who had seen their Social Security benefits reduced despite paying into the system.

The SSA expects all beneficiary records to be updated by November 2025, and most affected beneficiaries will begin receiving their new monthly benefit amount in April 2025 (for their March 2025 benefit).

Types of Social Security Benefits

Retirement Benefits

Retirement benefits represent the most common type of Social Security benefit, providing monthly payments to eligible workers who have reached at least age 62 and earned sufficient work credits. The amount you receive depends on your earnings history, the age at which you claim benefits, and various other factors.

The earnings test affects those who claim benefits before their FRA and continue working. Benefits may be reduced if earnings exceed certain thresholds, though these reductions are not permanent and benefits are recalculated at full retirement age.

Disability Benefits

Social Security Disability Insurance (SSDI) provides benefits to workers who become disabled and cannot work. The disability must be expected to last at least one year or result in death, and applicants must meet both medical and work credit requirements.

The work credit requirements for disability benefits vary by age, with younger workers needing fewer credits than older workers. SSDI benefits are calculated using the same formula as retirement benefits, and recipients may also be eligible for Medicare coverage after receiving SSDI benefits for 24 months.

Survivor Benefits

Survivor benefits provide crucial financial support to the families of deceased workers. These benefits can go to surviving spouses, children, and in some cases, dependent parents. The amount depends on the deceased worker’s earnings record and the relationship to the survivor.

Survivor benefits can begin as early as age 60 for surviving spouses, or earlier if they are caring for the deceased worker’s children. The benefit amount varies based on the survivor’s age when they claim benefits and their relationship to the deceased worker.

Social Security for Expatriates

Eligibility While Living Abroad

Over 700,000 Social Security recipients currently live outside the United States, and U.S. citizens can typically receive their benefits while residing abroad. The Social Security Administration defines living outside the U.S. as residing outside the District of Columbia, Puerto Rico, U.S. Virgin Islands, Guam, Northern Mariana Islands, or American Samoa for at least 30 consecutive days.

For expatriates, maintaining Social Security benefits while living abroad requires understanding specific rules and requirements. The SSA periodically sends questionnaires to verify that beneficiaries remain eligible for their benefits.

Restricted Countries

While most countries allow Social Security payments, there are important exceptions. The U.S. Department of the Treasury generally prohibits payments to residents of Cuba and North Korea. Additionally, payments generally cannot be made to those residing in several former Soviet republics, including Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan.

If you find yourself in a restricted country, your payments will be withheld until you leave and go to a country where payments can be made. The SSA provides screening tools to check if you can collect benefits in your chosen overseas destination.

Payment Methods

Most recipients abroad receive benefits electronically via direct deposit, either to a U.S. bank account or to a financial institution in a country with a direct-deposit agreement with the United States. The Social Security Administration no longer issues paper checks for benefit payments as of September 30, 2025.

Using a bank outside the U.S. may incur international transaction fees, so many expatriates choose to deposit payments into their U.S. account and then transfer funds overseas based on favorable exchange rates.

Totalization Agreements

Understanding International Agreements

Totalization agreements are bilateral agreements between the U.S. and currently 30 other countries, including major destinations like Australia, Canada, France, Germany, Japan, and the United Kingdom. These agreements serve three primary purposes: preventing dual taxation on Social Security benefits, helping individuals combine work credits earned in both the U.S. and a treaty country to meet eligibility thresholds, and ensuring unrestricted payment of benefits to residents of both countries.

How Totalization Works

The process typically involves obtaining a Certificate of Coverage, which serves as proof that you’re covered by the host country’s social security system. This certificate exempts you from paying U.S. Social Security taxes on income earned in that country, preventing double taxation.

Self-employed expatriates can avoid paying U.S. self-employment tax on worldwide income if a totalization agreement exists with their country of residence. Retirees benefit by being able to combine work credits from both countries to qualify for retirement benefits if their careers were split between nations.

Administrative Considerations for Expatriates

Maintaining Eligibility

The Social Security Administration requires periodic verification that beneficiaries remain eligible for their benefits. When moving abroad, you should contact the SSA immediately with your new address before you move. You’ll need to update pertinent information including your address, email, direct deposit information, and tax information.

Maintaining accurate records and responding promptly to SSA communications is crucial for uninterrupted benefit payments. The administrative burden may be greater for expatriates, but staying organized and proactive can prevent payment interruptions.

Special Rules for Non-Citizens

The rules are more restrictive for non-U.S. citizens receiving Social Security benefits. If you are not a U.S. citizen and fail to meet certain conditions for continued payments, and you spend six full calendar months outside the U.S., your payments will stop.

To restart benefits after this interruption, non-citizens must return to the U.S. for a minimum of a full calendar month. This makes obtaining U.S. citizenship particularly valuable for long-term residents who may want to retire abroad while maintaining their Social Security benefits.

Healthcare and Medicare Considerations

Medicare Coverage Limitations

One of the most significant challenges for American expatriates is healthcare coverage. Traditional Medicare does not provide coverage for hospital or medical costs outside the United States, creating a significant gap in healthcare protection for expatriates.

For full-time expatriates, enrolling in Medicare Part B may not make financial sense, as it provides no coverage abroad and requires monthly premiums. However, expatriates should be aware of potential late enrollment penalties if they decide to return to the U.S. later.

Most retirees should consider automatically enrolling in Medicare Part A (hospital coverage) at age 65, regardless of their residency plans. Part A typically has no premium for those who have worked and paid Medicare taxes for at least 10 years.

International Healthcare Planning

When retiring abroad, you’ll need to understand and become comfortable with different healthcare systems. Many expatriates purchase international health insurance or rely on their host country’s healthcare system. Some countries offer national health services that cover residents, while others require private insurance.

The lack of Medicare coverage abroad makes healthcare planning one of the most critical aspects of expatriate retirement planning. Consider both routine medical care and potential emergency situations when evaluating international healthcare options.

Tax Implications

U.S. Tax Obligations

All U.S. citizens and Green Card holders are subject to U.S. income tax laws regardless of where they live. This means that your income, including up to 85% of your Social Security benefits, may be subject to federal income tax even while living abroad.

The situation becomes more complex because many foreign governments also tax U.S. Social Security benefits, potentially creating double taxation. However, tax treaties with some countries can limit U.S. income tax or provide exemptions for foreign income.

International Tax Planning

Given the complexity of international tax law, consulting with an international tax expert during your planning process is highly beneficial. These professionals can help you understand the tax implications of your specific situation and ensure compliance with both U.S. and foreign tax requirements.

The Foreign Account Tax Compliance Act (FATCA) and Report of Foreign Bank and Financial Accounts (FBAR) requirements add additional complexity for expatriates. Proper tax planning can help minimize your overall tax burden while ensuring compliance with all applicable laws.

Financial Planning Strategies

Retirement Income Planning

Social Security alone is unlikely to provide sufficient income for a comfortable retirement. The program is designed to replace approximately 40% of pre-retirement income for average earners, making additional savings crucial through IRAs, 401(k)s, and personal investments.

For expatriates, retirement planning becomes more complex due to currency fluctuations, different cost-of-living levels, and varying tax treatments. Consider these factors when projecting your retirement income needs and planning your savings strategy.

Building Financial Resilience

Financial planners typically recommend saving at least two years’ worth of living expenses for emergencies. This emergency fund becomes even more important for expatriates who may face additional unexpected expenses.

Pay down all outstanding debts, including your mortgage, loans, and credit cards, before retiring to reduce your monthly expenses. Debt reduction is particularly important for expatriates who may face currency fluctuations that could affect their ability to service dollar-denominated debts.

Banking and Investment Considerations

International Banking

Choose financial institutions that can accommodate your international lifestyle. Consider banks with international presence or strong correspondent relationships that can facilitate overseas transactions. Direct deposit for Social Security benefits is strongly recommended due to potential mail delivery issues overseas.

Many expatriates maintain both U.S. and foreign bank accounts to facilitate currency management and local transactions. Understanding the tax reporting requirements for foreign accounts is crucial for compliance with U.S. tax laws.

Investment Portability

Some retirement accounts may not be as portable as others when moving abroad. Work with a financial advisor who understands international investing to ensure your portfolio remains appropriate for your new circumstances and tax situation.

U.S. tax law includes specific provisions affecting expatriates’ investment choices. Passive Foreign Investment Company (PFIC) rules can create significant tax complications for expatriates investing in foreign mutual funds or similar investments.

Future Considerations

System Sustainability

The Social Security system faces long-term financial challenges due to demographic changes and increasing life expectancy. The Social Security Trustees project that the trust fund reserves will be depleted by 2034 if no changes are made to the system.

Understanding these challenges is important for retirement planning, particularly for younger workers who may face benefit reductions or tax increases to maintain system solvency. However, even if the trust fund is depleted, incoming payroll taxes would still fund approximately 80% of scheduled benefits.

Technology and Modernization

The SSA continues to improve its online services and digital capabilities, making it easier for beneficiaries to manage their benefits regardless of their location. These improvements are particularly beneficial for expatriates who may have limited access to SSA offices.

Future technological improvements may include enhanced online services, improved mobile applications, and better integration with international banking systems.

Conclusion

Understanding Social Security requires navigating a complex system that has evolved significantly over nearly 90 years. The recent passage of the Social Security Fairness Act represents a major improvement in the system’s fairness and accessibility, particularly benefiting expatriates and those with diverse work histories spanning multiple countries or pension systems.

Successful Social Security planning requires understanding eligibility requirements, benefit calculations, and the various factors that can affect your benefits. For expatriates, additional considerations include payment methods, tax implications, administrative requirements, and healthcare planning.

The key to maximizing your Social Security benefits lies in early and comprehensive planning. Whether you plan to remain in the United States or retire abroad, understanding the system’s rules and staying informed about changes will help ensure you receive the full benefits you’ve earned through years of work and contributions.

Given the complexity of Social Security rules and their interaction with international tax and financial planning considerations, consulting with qualified professionals is often advisable. Social Security represents just one component of a comprehensive retirement plan and should be supplemented with other savings and investments to ensure a comfortable retirement, particularly for expatriates who face additional complexities of international living.
